    The invention relates to an assembly of a rolling mill. In particular, the invention relates, as a particular embodiment of an assembly of a rolling mill, to a scaffolding station of a rolling block. The invention likewise relates to a method for rolling rod or tubular rolling stock.
    From practice, different types of rolling stands are known for rolling bar or tubular rolling. On the one hand rolling mills are known in which the rolling rod or tubular rolling rolling over bearings with respect to radial movements are fixedly mounted in the rolling stand and possibly can learn about an arrangement of the bearing in eccentrically running discs employment. In these designs, the reaction force (rolling force) received by the rolls during rolling is introduced into the framework base body of the lattice stand. In an alternative design used in the present invention, the roll stand has a framework main body and at least one chock or rocker movable relative to the framework body, the chock having a roll. The chock is linearly movable relative to the framework body. In this design of a roll stand, an adjusting device is provided outside of the roll stand, which can act on the chock and hold the chock against the rolling force occurring in its position. The forces occurring during rolling are not absorbed in such scaffolding from the housing of the mill stand, but forwarded via the chock to the adjustment. Likewise, designs are known in which instead of the chock swing can be used. The wings are not like the chocks linearly displaceable, but rotatably mounted about a pivot axis in the frame housing. The pivot axis is either parallel to the roll axis, at a distance from the center plane of the roll, or arranged at right angles to the roll axis and parallel to the roll axis. In the case of storage of the roller in such a rocker, the roller strictly speaking describes a circular path around the pivot axis during the adjustment movement. However, in practice this is not significant at all because of the low deflection. The wings are also brought to their operating position with a hiring unit.
    In the construction of a roll stand with chock and / or rocker, which is essential for the present invention, the reaction forces (the rolling force) transmitted to the adjusting device are in turn passed on by the adjusting device into a supporting structure of the rolling mill or of the rolling block surrounding the rolling stand. Since the support structure is the actual rolling stand I ·· «t« · * «
    I -2 - surrounds the outside and therefore has considerable dimensions, resulting from the strains necessarily occurring under load elastic displacements of the Anstelleinheiten are also of considerable size. In the known from the prior art designs, the supporting structure to reduce these elastic displacements is made very solid, whereby the elastic strains occurring and the resulting deformations are reduced. However, this is only partially successful despite the considerable cost. For example, it is possible for the radial displacement of the attachment surface of a hydraulic adjustment unit, that is to say the surface on which the hydraulic adjustment unit is connected to the supporting structure, to be at full rolling force, based on the ideal roller center of the installation, of the order of magnitude of approx mm is located. If one observes that, for example, a target wall thickness of, for example, 8 mm is to be produced for rolled tube blanks, it can be seen that the radial displacement of the mounting surface of a hydraulic adjusting unit can significantly influence the dimensional stability of the product to be rolled. The considerable displacement of the hydraulic adjusting unit complicates the precise compliance of the
    Wall thickness tolerances of the finished product considerably, it can even make impossible in certain operating situations.
    The above-described construction principle of the relevant here rolling mills with chock have the further disadvantage that in a rolling mill several such rolling mills are often arranged at successive scaffolding sites. This results in an influence of the elastic springing on a scaffolding site by the rolling forces occurring at the adjacent scaffolding sites. This further complicates the compensation of the occurring displacement by the control of the hydraulic adjusting unit considerably.
    Another complication of the compensation of the elastic springing results from the fact that the entire supporting structure can be excited by the forces occurring in the operation to considerable vibrations in very complicated forms of vibration.
    Against this background, the invention has for its object to propose an assembly of a rolling mill, or a method for rolling rod or tubular rolling, in which the forces introduced into the chock during rolling forces can be better absorbed.
    The object is achieved by the assembly of a roll stand according to claim 1 and by a method for rolling rod or tubular rolling stock according to claim 6. Advantageous embodiments are given in the subclaims and the following description. • * * 4 • * * 4 ♦ ♦ * * -3-
    The invention is based on the basic idea to press the adjusting unit for the chock, or the rocker with a biasing unit from the outside with a compressive force against the framework body, or - which is technically equivalent - between the adjusting unit for the chock, or the Rocker and the framework body to provide a bias unit that generates a spreading force with which the main body of the adjusting unit and the framework body are pressed apart. In this way, mechanical-form-fitting connections between the body of the adjusting unit and the framework body can be avoided. Either the basic body of the adjusting unit can be pressed by means of pressure force against the framework main body without any further connecting element. Or it is a biasing force generating bias unit is used, which is indeed designed more complex in relation to the first alternative, but it makes it possible to simplify the connection of the rolling stand and the Ansteileinheit with a supporting structure, such as a roll stand.
    Starting from the assembly according to the invention, the method according to the invention is based on the basic idea of producing a compressive force or spreading force by means of the force-generating unit which is greater than the maximum expected rolling force occurring during operation. According to this basic idea, therefore, the main body of the adjusting unit is pressed with a higher force against the framework main body, or pressed on the use of an expanding force of this, as the force acting on the adjusting unit or the rocker of the rollers on the Anstelleinheit force. This ensures that the radial displacement of the adjusting unit is significantly lower than in the known from the prior art assemblies. In addition, it is possible not to make the width of the rolling stands larger than in the prior art embodiments in which the reaction force of the hydraulic adjusting unit is absorbed by the surrounding supporting structure. In the design of the assembly according to the invention for carrying out the method according to the invention, namely, the support structure can namely be designed comparatively easily. Finally, in the implementation of the method according to the invention mentioned above mutual interference of the scaffolding places can be avoided.
    In a preferred embodiment, the assembly according to the invention and the method according to the invention can still be carried out in such a way that the reaction forces (the weaving forces) are absorbed by an outer structure (supporting structure). The principle of pretensioning the adjusting unit from the outside against the skeleton body (be it by means of pressure or by means of spreading) allows the force-carrying external structure to be comparatively light and thus "... 4 * * II * * * * * * * ···· »*» · * · -4 - cheap and energy efficient to build. Nevertheless, cause in this design, thereby inevitably resulting in the outer structure higher elastic deformations no large, depending on the actual effective rolling force displacements of the adjusting unit. Also, the disturbing mutual influence of the individual scaffolding places is avoided.
    The assembly of a rolling mill according to the invention has a rolling stand which has a framework body and at least one relative to the framework body movable chock or a relative to the framework body movable rocker, wherein the chock or the rocker has a roller. To simplify the following description of the invention, the following description of the invention is based only on the design of the module with a chock, without limiting the embodiments and advantages described below to this design with chock. The embodiments and advantages described below can also be realized with a rocker (s).
    In a preferred embodiment, the rolling stand has at least two rollers having chocks, particularly preferably, the rolling mill has three relative to the skeleton body movable chocks, each having rollers. It is also possible that the rolling stand has four or more chocks relative to the framework body, each having rollers. The chock is formed in a preferred embodiment linearly relative to the framework body or in an alternative embodiment along a circular arc relative to the framework body. The roller provided in the respective chock can have a roller shaft, which is rotatably mounted in a base body of the chock relative to the installation body.
    The assembly of a rolling mill according to the invention has an adjusting unit with a base body, an adjusting unit and a first connecting part which, at least in the operating situation, are suitable for receiving the force introduced by the roller via the built-in piece. In a preferred embodiment, the adjusting unit is designed as a hydraulically acting force generating unit with a cylinder and a piston arranged in the cylinder, wherein the force is generated by means of a pressurized hydraulic fluid disposed between the piston and the cylinder. In such a design, it is conceivable to carry out the cylinder as the base body of the adjusting unit and to form the piston, or a further component connected to the piston as the first connecting part, which acts in a preferred design directly on the body of the chock and in this way a can exert force generated by the hydraulic piston-cylinder unit as a rolling force on the roller. Alternatively, it is conceivable to form the adjustment pneumatically or electrically.
    In a first alternative, the assembly of a rolling mill according to the invention provides a prestressing unit with a force generating unit and a second connecting part which, at least in the operating situation, is suitable for exerting a force generated by the force generating unit on the base body of the adjusting unit and the basic body of the adjusting unit with a compressive force to press against the framework body. The force acting on the adjusting unit by the roller via the chock and the first connecting part is transmitted by the latter into the basic body of the adjusting unit. According to the invention, this rolling force acting on the base body by the adjusting unit now counteracts a force which is generated by the force-generating unit and likewise acts on the base body. As a result, when the force generated by the force generating unit is larger than the respective rolling force acting on the base body by the adjusting unit, the base body of the adjusting unit is applied to the skeleton main body with the differential force (resulting rolling force and biasing force generated from the outside by the force generating unit) pressed. As a result, the adjusting unit does not change its position relative to the framework main body independently of the respective prevailing rolling force, and the force generated by the force-generating unit constantly acts in the outer supporting structure.
    Even in the case that the force generated by the force generating unit is smaller than the rolling force occurring during operation, an advantage according to the invention results: in this case, on the one hand, the full rolling force acts on the outer support structure during the rolling operation, and on the other hand, in the situations in where the rolling force is smaller in magnitude than the biasing force generated by the force generating unit, the outer support structure is still subjected to the biasing force. The occurring maximum displacement of the adjusting units corresponds in this case therefore only the difference between maximum rolling force and biasing force and not, as in the prior art, the full rolling force. Preferably, the biasing force is in magnitude but greater than the maximum occurring rolling force.
    In order to generate the force with which the main body of the adjusting unit can be pressed against the framework body, a hydraulic piston-Zyiindereinheit is also preferably used as a force-generating unit. Particularly preferably, the cylinder of such a piston-cylinder unit can be connected to a support structure and the piston can be used with such a piston-cylinder unit as a second connecting part, which acts on the basic body of the adjusting unit at least in the operating situation and is suitable for one of the force-generating unit generated force on the main body of the • ·· t I it * * * * * * · ** * t 1 * ittit * ··· »« -6-
    Exercise adjuster and press the body of the adjusting unit with a compressive force against the framework body. Alternatively, it is also conceivable to form the force generating unit as a pneumatic unit or electrical unit.
    In an alternative embodiment of the assembly according to the invention, a biasing unit may be provided with a force generating unit capable of generating a spreading force and configured with a first component arranged to exert the spreading force generated by the force generating unit as a compressive force on the framework main body , Further, this second alternative, a second component of the bias unit, which is arranged so that it can exert the spreading force generated by the force generating unit as a compressive force on the body of the Anstelleinheit, so that the framework body and the body of the Anstelleinheit in the operating state with that of
    Force generating unit generated spreading force are pressed apart. The force generating unit has an inner longitudinal stop and thereby brings the main body of the adjusting unit to a defined distance from the framework main body. Those in this condition, i. When force applied to the inner longitudinal stop force generating unit, prevailing contact pressure between the force generating unit and between the force generating unit and the body of the Anstelleinheit is determined in size by the elasticity of the outer support structure. In a preferred embodiment, the extension path of the force-generating unit is determined so that the self-adjusting biasing force is greater than the maximum occurring during rolling operation of the stand rolling force. In this case, the advantage already described above for the first device according to the invention results that the adjusting units do not change their position relative to the framework main body independently of the respective prevailing rolling force, and that a constant prestressing force acts in the outer supporting structure.
    As a force-generating unit of such an alternative biasing unit can also be provided a hydraulic piston-cylinder unit. Depending on the design, it is advantageous to design such an alternative prestressing unit with a plurality of force-generating units, in particular preferably with a plurality of hydraulic piston-cylinder units. The use of multiple force generating units can be e.g. allow the entire Anstelleinheit seen in the rolling direction of the block narrower form and thereby allow a particularly close distance to the frame. Likewise, cylinder and piston may be annular and, for example, the first connecting part of the adjusting unit may be formed annularly surrounding.
    In preferred embodiments of the assembly according to the invention, the second connecting part of the biasing unit acts only on the main body of
    Anstelleinheit, but is not firmly connected to the body of the Anstelleinheit. This embodiment makes it possible to rapidly expand the rolling stand from a supporting structure. The connection of the first connecting part with the base body of the chock can be designed as a solid, detachable connection. Thus, for example, in overhead chocks in the rolling breaks between two tubes or rods, the chocks remain in position and do not fall below its own weight but there are also conceivable embodiments in which the chocks (or in this case: swing) by Spring packs that just overcome the weight, are pushed outward, and thus can be held by the first connecting parts by pure pressure force over area investment in their position.
    In a preferred embodiment, in the alternative, in which the biasing unit is listed with a force generating unit and a second connecting part, which is suitable at least in the operating situation, to exert a force generated by the force generating unit on the body of the Anstelleinheit and the body of the Anstelleinheit with To press a compressive force against the framework body, provided a support structure on which the bias unit is supported. Such a support structure can be, for example, as a rolling mill, the Anstelleinheit or the Anstelleinheiten (if multiple chocks are provided on the rolling stand) and the bias unit, or the biasing units (if multiple Anstelleinheiten provided) spanning structure, for example as an annular, closed Structure be formed. Likewise, such a structure may be C-shaped, for example. In this supporting structure, the constant forces are introduced, which arise in the bias unit when generating the compressive force with which the main body of the adjusting unit is pressed against the framework body. As a result, the supporting structure is elastically deformed, for example stretched. However, upon reaching the operating condition where the constant compressive force is generated, no further change in the state of deformation of the supporting structure occurs when the rolling forces are below the compressive forces. Since the load-bearing structure no longer needs to absorb alternating stresses, it can be made easier.
    In an alternative, likewise preferred embodiment of a construction in which the biasing unit is designed with a force-generating unit and a second connecting part which, at least in the operating situation, is suitable for exerting a force generated by the force-generating unit on the basic body of the adjusting unit and the basic body of the adjusting unit with a compressive force against the framework body, it is provided that the bias unit itself is formed as a complex structure and forms a structure with a first and a second end, wherein the first and the second end are connected to each other via the force generating unit the bias unit forms a closed structure surrounding the rolling stand. The force generating unit contracts the first end and the second end in the operating state with a contraction force. In this embodiment, the second connecting part is designed such that it can derive a pressure force acting radially on the base body of the adjusting unit from the prestressing of the closed structure caused by the generation of the contraction force. Within the closed structure, in a preferred embodiment further force generating units may be provided to produce a particularly good contractive force. In the preferred embodiment described herein, in which the biasing unit itself is formed as a structure surrounding the rolling mill and within which the biasing force (the compressive force acting on the main body of the pitching unit by the second connecting member) is generated, the rolling stand and the adjusting unit can be made In particular, the connection of the adjusting unit with the biasing unit are made particularly simple, which may allow a rapid change of the rolling stands.
    In a preferred embodiment, wherein the biasing unit includes a force generating unit capable of generating an expanding force and a first member arranged to be capable of performing the spreading force generated by the second force generating unit as a pressing force on the skeleton body; a second component is provided, which is arranged so that it can exert the spreading force generated by the force generating unit as a compressive force on the body of the Anstelleinheit so that the framework body and the body of the Anstelleinheit is pressed apart in the operating state with the spreading force generated by the second force generating device , A support structure is provided, on which the base body of the adjusting unit is supported.
    The inventive method for rolling rod or tubular rolling in an assembly of a rolling mill according to the invention described above provides that the pressure force generated by the force generating unit, or generated spreading force is greater than the maximum expected rolling force occurring during operation. The implementation of such a method makes it possible-as described above-to reduce the reaction forces resulting from the generation of the rolling force in the setting unit to 0 by the pressure force or the spreading force and to prevent these reaction forces from being introduced into a possibly present supporting structure. The supporting structure is thus burdened solely by the constant biasing force that arises when generating the compressive force, or the spreading force. 4 * * * * «*» -9-
    The assembly of the invention and the inventive method are particularly preferably used for rolling rod or tubular rolling. Particularly preferred for rolling of so-called tube blanks, in which a tube blank on an internal tool, for example a dome, is stretched by longitudinal rollers.
    The invention will be explained in more detail with reference to a drawing illustrating only embodiments.

    The assembly according to the prior art shown in FIG. 1 shows a rolling stand 1 which has a framework body 2 and in each case mounting chocks 3, 4, 5 movable linearly relative to the framework body. Each chock 3, 4, 5 has a roller 6, 7, 8. The chocks 3, 4, 5 are arranged in the framework body 2 such that the rollers 6, 7, 8 carried by them are arranged in a star shape relative to one another and form a rolling caliber. * «Ft * • 4 10
    The known from the prior art assembly according to Figure 1 has three Anstelieinheiten 9, 10, 11. Each adjusting unit 9, 10, 11 has a hydraulic piston-cylinder unit, the cylinder 12 is connected to a supporting structure 13 and the piston 14 is formed as a first connecting part, which is connected in the illustrated operating situation with the main body of the chock and suitable is to change the position of the chock and thus the roller (6) in relation to rolling axis depending on the position of the piston of the Verstublleinheit and to absorb the resulting rolling rolling force. The Ansteileinheiten 10 and 11 are performed the Anstelleinheit 9 comparable.
    When rolling arise radially acting reaction forces Fw, which are introduced from the roller 6 via the chock and the piston 14, and the cylinder 12 of the Anstelleinheit 9, or the cylinders of the Anstelleinheiten 10 and 11 in the supporting structure 13. Depending on the control, as well as on the parameters of the incoming rolling stock (such as dimensional and temperature deviations), the force curve of this rolling force Fw is dynamic and thus leads to a dynamic loading of the support structure 13. Further, the reaction forces Fw cause considerable due to the size of the construction Displacements of the supporting structure 13 facing the end of the cylinder 12 of the starting unit 9, which may be in practice on the order of about 1 mm,
    In the case of the assembly shown in FIG. 2, the components that remained unchanged in relation to the assembly of the prior art are identified by the same reference numerals. The adjusting unit 19 of the embodiment of the invention shown in FIG. 2 has, in addition to the cylinder 22 of the piston-cylinder unit, a base body 23. Furthermore, the adjusting unit 19 has a piston 24 acting as a first connecting part, which in the illustrated operating situation is connected to the main body of the chock 3 and is suitable for exerting a force generated by the adjusting unit designed as a piston-cylinder unit as a rolling force on the roller 6 , In addition to the starting unit 19, a biasing unit 30 is provided with a force generating unit in the assembly according to the invention, which is formed as a cylinder 31 and a second connecting part formed as a piston 32 having the piston-cylinder unit. The cylinder 31 of the force generating unit is connected to the supporting structure 13. In the illustrated operating situation, the piston 32 of the biasing unit 30, which is designed as a second connecting member, presses this basic body of the starting unit against the framework body 2 with a compressive force F0 generated by the force generating unit. During rolling, the outward rolling force Fw acts on the actuating unit 19. If the pressure force FD is present greater than the occurring rolling force Fw, the difference between the compressive force FD and the rolling force Fw as the pressure force from the main body 23 becomes "* * *» * I »'* * Ψ 9 * · Μ * ** * *» "i". - »·· *» f · I · * ··· ♦ As a result, the load-bearing structure is always acted upon by the reaction force of the constant pressure force Fd independently of the actually acting rolling force Fw. in the embodiment shown as Figure 3, the bias unit is formed as a closed, the rolling stand 1 surrounding structure. The thus executed bias unit 39 has a first end 40 and a second end 41. The first end 40 and the second end 41 are connected to one another via a second force-generating unit designed as a piston-cylinder unit 42 such that the pretensioning unit 39 forms a closed structure surrounding the rolling stand 1. In the embodiment shown in FIG. 3, two further piston-cylinder units 43 and 44 are provided within the structure forming the biasing unit 39. The piston-cylinder unit 42 contracts the first end 40 and the second end 41 in the operating state with a contraction force. Likewise, the piston-cylinder units 43 and 44 contract the ends of the structure connected by them with contraction forces. The arc-shaped second connecting parts 45, 46 and 47 are designed such that they derive from the bias caused by the generation of the contraction forces in the closed structure a radially acting on the main body of the Anstelleinheit 19 pressing force F0.
    The preload unit 39 formed as a closed structure is supported on the substrate 50 by supporting structures 48 and 49.
    The embodiment shown in FIG. 4 has a prestressing unit which, in its basic construction, resembles the prestressing unit shown in FIG. 3 in the form of a closed structure surrounding the rolling mill stand. In the embodiment shown in Figure 4, however, the closed structure is formed by a Zugmittei, for example a cable 60 having a first end 61 and a second end 62. In this embodiment, the first end 61 and the second end 62 are connected to each other via a force-generating unit formed as a piston-cylinder unit 63 such that the biasing unit 59 forms a closed structure surrounding the rolling stand. The force generating unit contracts the first end 61 and the first end 62 in the operating state with a contraction force. The second connection part 64 is designed in such a way that it can derive a pressure force FD acting radially on the base body of the adjustment unit from the prestressing of the closed structure caused by the generation of the contraction force.
    The biasing unit in the embodiment shown in FIG. 4 is held in a supporting structure 65. I «- 12 -
    The embodiment shown in Figure 5 shows an embodiment of the second alternative of the assembly according to the invention. In this alternative, a biasing unit 70 is designed with a force-generating unit designed as a piston-cylinder unit 71. This piston-cylinder unit has an annular piston 76 and an annular cylinder 72, which surrounds the first connecting part 74 of the adjusting device 69. Furthermore, the biasing unit 70 has an inner longitudinal stop 75. The piston-cylinder unit 71 can generate a spreading force. The cylinder 72 formed as a first component is arranged such that it can exert the spreading force generated by the force-generating unit as a compressive force on the base body 73 of the adjusting unit 69. The annular piston 76 embodied as a first component is designed such that, when the spreading force is applied, it moves against the inner longitudinal stop 76 and thereby brings the main body 73 of the adjusting unit to a defined distance from the framework main body 2. The pretensioning force acting between the adjusting unit 69 and the pretensioning unit 70 and between the pretensioning unit 70 and the framework main body 2 results in consequence of the applied displacement of the adjusting device 69 in conjunction with the elasticity of the outer supporting structure 13.
    The embodiment shown in FIG. 6 is comparable in its basic structure to the embodiment shown in FIG. However, in the embodiment shown in Figure 6, the supporting structure 83 is formed as a C-shaped arc. The use of such a C-shaped supporting structure 83 makes it easy to change the rolling stand. The biasing unit 80 and the adjusting unit 89 can be pivoted as shown in FIG. 6 by dashed lines, thereby releasing a space through which the rolling stand 1 can be removed from the supporting structure 83.
    The embodiment shown in Figure 7 represents an alternative to the embodiment shown in Figure 6. As shown in Figure 7, it is possible to form the supporting structure 93 as a C-shaped arch, but at its open end with further, with the supporting Structure biased but releasably biased biasing means 94 and thereby realize the technical advantages of a ring-closed supporting structure.
