    [0001] The invention relates to a press to discharge a end of oblong parts, knowing that the press to present at least two longitudinally divided matrices, comprising at least two parts of matrix. The invention also relates to a method for discharging an end of oblong pieces in a press to be repressed which has at least two longitudinally divided matrices, comprising at least two parts of matrix. Pressing presses and corresponding methods for discharging an end of oblong pieces are for example known from DE 32 40 689 A1, JP 60-3938 A and WO 2012/150564 A1. DE 32 40 689 A1 describes in particular a loading device for handling tubes on a pressing machine having vertically divided dies, wherein the dies comprise two opposite etchings. In order to introduce into the upper etching a tube whose end has to be subjected to a roughing back, the respective die is opened, so that the tube can be moved in a free space between the two die halves. Then, the die halves close and a pushback operation can be performed. As a result, the two die halves open again and the rough-edged tube is moved into the lower engraving for finishing discharge, while a new tube can be moved into the die. upper engraving for roughing back. The reprocessing machine known from JP 60-3938 A 25 comprises at least two two-part matrices, knowing that two halves of the two-part die can be respectively displaced, to open and close said die, along two surfaces. sliding of a die frame which are arranged obliquely and conically relative to each other. The closure and opening of the die is effected by means of clamping jacks disposed on the die frame which, by means of a suitable design mechanism, are operatively connected to the two halves of the die in two. respective parts so that the two die halves can be moved in translation along the sliding surfaces. In the case of the press to be discharged known from WO 2012/150564 A1, intended to repress an end of a metal tube, dies provided for this purpose consist of two movable halves. These halves are respectively held in a rotating arm, the two rotating arms having a common hinge point. The die halves are rotatable around this point, so that the two halves of the dies can be respectively open or closed. However, for design reasons, known generic presses are generally generally of an excessive size, and / or they have a vulnerable opening and closing mechanism, and / or their opening. and their closure takes too much time. It is an object of the present invention to provide a discharge press and a method for discharging an end of oblong pieces which operate in a more efficient and energy efficient manner. The object of the invention is achieved by a press of the type mentioned in the introduction which is characterized in that a first of the two die parts is disposed on a first turret-matrix holder, and a second of the two parts The die is disposed on a second die holder turret. The fixed object is also achieved by a method of the type mentioned in the introduction which is characterized in that the respective die portions of the two dies are alternately moved in a discharge position and a delivery position. A press for discharging an end of oblong pieces, which press has at least two longitudinally divided matrices comprising at least two die portions, thus functions more efficiently and energetically better if a first of the two die portions is disposed on a first die holder turret and a second of the two die portions is disposed on a second die holder turret. In that a first one of the two die parts is arranged on a first die holder turret and a second one of the two die parts is disposed on a second die turret, it is possible, with an appropriate configuration, to design an opening and closing mechanism for the matrix of a very simple structure and remarkable operational safety. In addition, with a suitable configuration, the matrix parts of several matrices can be integrated in a very small space inside the press, so that the press thus equipped can be operated from a much more efficient way. By means of the press or its dies can be machined end a large number of different oblong parts. This is for example here, tubes, bars or the like. Particularly note here are the drill rods, which can be machined or repressed only on presses to repress very large, with matrices of a corresponding configuration. The present invention therefore particularly relates also presses to discharge for drill rods of appropriate configuration, so large presses of a corresponding design.
    [0002] The matrix here preferably consists of two die halves movable relative to each other. However, with a corresponding configuration, it may also consist of more matrix parts, which then make up a matrix. In the latter case, therefore, in the presence of several matrix parts per die, several matrix turrets may also be provided, however, that more stringent requirements are placed on the mechanism of movement and advancement for the individual matrices. In addition, on the basis of the present advantageous design, the respective die can, with a suitable configuration, be opened and closed in a very simple manner in terms of process. A method for discharging an end of elongate pieces in a blow-molding press having at least two longitudinally divided dies comprising at least two die portions also functions more efficiently and energetically better if parts of the die respective die of the two dies are alternately moved in a discharge position and a delivery position. Advantageously, the respectively alternately displaced die portions of the two dies are moved in mutual synchronism, so that the different dies can be opened and closed significantly faster. This applies to both the die-associated die portions, which may optionally be simultaneously rotated by means of two die-holder turrets, the die portions which are carried or alternatively displaced by the respective die-holder turret.
    [0003] In this case, a particularly simple control can be obtained if two first die portions of the two dies and / or two second die portions of the two dies are respectively simultaneously moved between the delivery position and the delivery position. Preferably, the simultaneous displacement is carried out respectively with an identical trajectory, which can be implemented in a particularly compact and simple manner from the point of view of the construction. Here it is possible to obtain in a simple manner an identical trajectory if the two die parts are arranged on a rigid body, for example on a matrix turret, knowing, however, that a separate servocontrol can also be envisaged. It is furthermore advantageous that the displacement between the discharge position and the delivery position takes place during a single heating and that a discharge operation is carried out with each of the dies in the discharge position. This allows a very energy efficient multi-stage reprocessing operation, which optimally takes advantage of the rapid matrix change. For the purposes of the invention, the expression "during a (single) heating" means that the part, between two delivery operations, must not be or is not heated again or repositioned. In particular, repositioning the workpiece from a workpiece position thus becomes redundant, so that the present feed back process can be performed in a shorter and more energy efficient manner. An improved variant of the method provides that the displacement is effected by a rotation in the same direction and / or in opposite directions of the matrix turrets. A rotation in itself already has the advantage that it can in general be carried out quickly and reliably even for heavy elements, and therefore also for the heavy die of a large press. Rotation in the same direction allows, for example, with a suitable configuration, a very fast change between two matrices - 5 - whose matrix parts are mutually facing each other, since they then come directly to one another. other, or move away directly from each other. Conversely, rotation in opposite directions makes it possible, with an appropriate configuration, for mutual engagement of respective protrusions which are formed, for example, by the die parts, so that they can move along each other, knowing that this last displacement can also be made possible, in particular for very complex matrix turrets and in particular cases, for example when three or more matrix portions are arranged on a matrix turret, by a displacement of at least one of the matrix turrets of a working position in a displacement position in which the matrix turrets do not interfere. It is furthermore advantageous if the first two die portions on the first die holder turret, and the two second die portions on the second die holder turret are disposed respectively opening towards each other. The two matrix-forming die parts can thus be opened or closed in a constructively simple and fast manner.
    [0004] If the matrix portions of a matrix are, in a delivery position of the two matrix-bearing turrets which is associated with this matrix, turned towards each other, each of the matrices can be respectively closed or opened by a simple way. A very advantageous embodiment provides that the longitudinal division of the dies takes place in a plane which does not intersect the axes of rotation of the respective die-bearing turrets. If the longitudinal division of the dies takes place in a plane which does not intersect the axes of rotation of the respective die turrets, the working forces acting on the respective die can be considerably better compensated. It is therefore advantageous for the axis of rotation of the respective matrix-bearing turret to be disposed outside a partition plane formed by the longitudinal division of this turret. If, in addition, the respective die portion is disposed on the same side of the plane as the associated axis of rotation of the associated die-holder turret, the risk of the die portions protruding to such an extent can be minimized. that the directly adjoining matrix turrets interfere with each other when the matrix is changed. This provides a closure and opening of the matrices constructively simple and reliable. Both the construction structure and the conduct of the method 5 can be simplified here if the two matrix turrets are arranged on axes of rotation parallel to each other. It is appropriate that at least one die portion of a third longitudinally divided die is respectively disposed on the two die turrets. The advantage of a much faster and more accurate matrix change to a third matrix is thus obtained, although it may last a little longer than the direct change between the first and the second matrix, or even if Matrix change to this third matrix can no longer take place during a warm-up. It will be understood that additional die portions of further longitudinally divided matrices may optionally also be provided on the die turrets, as long as there is sufficient room for it. A corresponding matrix change may be implemented with a simple constructional structure if open-to-the-die pairs of die portions are respectively provided on both die-holder turrets. It is furthermore advantageous that at least one of the two, preferably the two matrix turrets, is axially and / or radially movable between a working position and a moving position. Advantageously, the different matrices can be arranged free from each other in the displacement position, whereas in the working position, the matrix turrets interfere with each other and a completely free rotation should not occur. 30 not be possible. Moreover, with a suitable configuration, it is possible to obtain a free rotation while the two matrix turrets rotate in opposite directions, for example by the fact that - in a manner similar to gears - the projections formed by the parts of respective die and the recesses left between the die portions engage each other. However, this seems to work only to the extent that no part is in its working position, thereby preventing rotation. A displacement position is possibly also judicious for such a change of matrix. Particularly in the context of large presses, it is advantageous that the press to be discharged is horizontal, and / or that a workpiece passes through a cross member, preferably a free cross member, of the press to be repressed during the pressing or in a pressing position. The present press can be advantageously improved by the fact that it has a central tube clamping with preferably at least three clamping jaws can be clamped against each other, which are or can be clamped by means of particular a keying system. By means of this central tube clamping, the oblong parts can be so well positioned that the two matrix-forming die portions can, by means of the die-holder turrets, be advantageously rotated along curved paths on either side. an oblong piece. These curved paths are preferably intersected in the region of the pressing position or the repressing position. It will be understood that the features of the solutions described above may be optionally also combined, in order to be able to implement the advantages in a corresponding cumulative manner. Other advantages, objectives and properties of the present invention will be explained with the aid of the following description of exemplary embodiments, which are in particular also shown in the accompanying drawings in which: FIG. schematic side view of a press to be repressed with a first matrix portion associated with a matrix and fixed on a first matrix-bearing turret, and with a second matrix portion associated with this matrix and fixed on a second matrix turret ; Figure 2 is a schematic representation of the arrangement of Figure 1 according to section A-A of Figure 1; Figure 3 shows an arrangement similar to Figure 1 of another press to repress, in a representation similar to Figure 2; and FIG. 4 shows another press to be discharged in a representation similar to FIGS. 2 and 3. The press 1 represented by way of example in FIGS. 1 and 2 is suitable for discharging oblong pieces 2, such as 3 of the tubes 4 consist of tubes 4. The press 1 has a ground support unit 5 with elements 7 of transverse beam (referenced by way of example) inserted in the ground 6, so that the press 1 to be discharged is generally fixedly assembled to the ground 6. This ground support unit 5 carries, on the one hand, a fixed crossmember 8 and, on the other hand, a free crossmember 9, between which are placed four tie rods 10 in total ( referenced by way of example only). The fixed cross member 8 and the free cross member 9 are thus assembled together by means of these tie rods 10. On the side 11 of the free cross member 9 is a central tube clamping unit 16, intended to clamp the oblong parts 2, which 15 comprises three clamping jaws 17 that can be clamped against each other, which can themselves be clamped with the oblong piece 2 by means of a keying device 18. The clamping tube 16 allows in particular to tighten and maintain reliably during the discharge of the large tubes 4 of drill rods 3 or the like. In addition, a set of dies 20, which comprises a total of four longitudinally divided dies 21 (see FIG. 2 by way of example), is still on the side 11. To open or close these dies 21, two door turrets 22 and 23 are provided on the array 20, with the first array turret 22 rotating about a first axis of rotation 24, and the second turret supporting matrix 23 about a second axis In this exemplary embodiment, the two axes of rotation 24 and 25 are mutually aligned, knowing that the two axes of rotation 24 and 30 can also be arranged in a different manner. These two matrix turrets 22 and 23 are driven by means of a drive motor 26 which, by a synchronization mechanism 27, is functionally connected to the two matrix turrets 22 and 23 or to their axes of rotation 24 and so that the two matrix turrets 22 and 23 can rotate asynchronously or synchronously with respect to each other, in order to open or close the respective matrix 21 in the region (pressing position 45) of the oblong piece 2. Each of the longitudinally divided matrices 21 is respectively composed of two discharge shells (not specifically referenced) or die portions 22.1 and 23.1, respectively 22.2 and 23.2, respectively 22.3 and 23.3 respectively 22.4 and 23.4 (see FIG. 2), knowing that the first respective matrix portions 22.1, 22.2, 22.3 and 22.4 are formed by a body of revolution (not specifically referenced) of the first tower the matrix holder 22, and the respective second die portions 23.1 and 23.2, 23.3 and 23.4 also by the revolution body of the second die holder turret 23. In other words: the first of the four dies 21 of the array of dies 20 consists of a first pair of dies made of matrix portions 22.1 and 23.1. In a corresponding manner, the second of the four matrices 21 of the array of matrices 20 consists of a second pair of matrices consisting of the array portions 22.2 and 23.2. The third of the four matrices 21 of the matrix set 20 consists of a third pair of matrices consisting of the matrix portions 22.3 and 23.3. And the fourth of the four matrices 21 of the array of matrices 20 consists of a fourth pair of matrices consisting of the array portions 22.4 and 23.4. The respective first die portion 22.1, 22.2, 22.3 and 22.4 is thus disposed on the first die holder 22, and the respective second die portion 23.1, 23.2, 23.3 and 23.4 on the second die holder 23.
    [0005] That being so, while the die assembly 20 with its components, the drive motor 26, the elongated member 2 and the tube clamping unit 16 therefor are substantially disposed on the first side 11. a die frame assembly 36 comprising at least one die frame 37 and a die mount ram 38 therefor, and further a press mandrel 39 and a press ram unit 40 therefor are disposed on the side 35 of the fixed beam 8. By means of the die frame ram 38, the die frame 37 can be moved in the feed direction 41 to the die set 20, or back.
    [0006] The die frame 37 receives the closed die 21 located respectively in the press-and-discharge position 45 (see FIG. 2), in which matrix is disposed an end (2A) of the piece 2 located in the position 46, and it encloses this matrix so that, during a discharge operation, the two pairs of respective matrices remain fixedly assembled together. In this pressing or discharge position 45, the corresponding discharge forces acting on the matrix portions 22.1-23.1, 22.2-23.2, 22.3-23.3 or 22.4-23.4 are therefore correctly absorbed by the die frame 37, so that that the set of dies 20 is all the less solicited. The actual discharge operation is effected in a manner known per se by means of the pressing ram unit 40, which presses the pressing mandrel 39 through the die frame 37 into the oblong piece 2 in the pressing position 45 and driving the die frame 37 together with the die frame jacks 38 in the feed direction 41, to push the end of the clamped piece 2 into the tube clamping unit 16 . It will be understood that alternative embodiments of the invention may also be envisaged here, in particular possibly also without a pressing mandrel 39. The components of the matrix frame assembly 36 are mounted on a crossmember 47 in this embodiment, these matrix turrets 22, 23 respectively receive the four discharge matrices called matrices 21, as shown in particular in FIG. FIG. 2. By rotation of the matrix turrets 22, 23 around their respective axes of rotation 24, 25, the discharge shells or conveyed matrix parts 22.1, 22.2, 22.3, 22.4, respectively 23.1, 23.2, 23.3, 23.4 can be combined into a closed matrix 21. The respective longitudinal division of the matrices 21 located respectively in the pressing position 45 or the discharge position 30 is effected here in a lan 50 which does not intersect the axes of rotation 24 and 25 of the respective die turrets 22 and 23. In addition, the respective die portion 22.1, 22.2, 22.3, 22.4, being in the pressing position 45 or starting, the first turret carrier 22 is disposed on a side 51 of the plane 50 35 on which is the axis of rotation 24 of the first turret-matrix 22. In a corresponding manner, the respective die portion 23.1, 23.2, 23.3, 23.4 being in the pressing position 45 is on the side 52 of the plane 50 on which is disposed the associated axis of rotation 25 of the associated die holder turret 23. By the arrangement counter-rotating or alternatively opening the matrix parts 22.1-22.2, 22.3-22.4 or 23.1-23.2, 23.3-23.4 respectively to each other, the medium of the tube 4 to be repressed is not cut when the first delivery is changed. at the second repression. Advantageously, this directly allows a double backflow during a warming. For the change between the different matrices 21, the matrix turrets 22 and 23 are rotated in the same direction around the respective axis of rotation 24, 25. By a rotation in the same direction of the turrets holder-matrix 22 23, a change can be made between the two dies 21 formed by the die portions 22.1, 23.1 and 22.2-23.2, and the two dies 21 formed by the die portions 22.3, 23.3 and 22.4, 23.4, which is then possible only without piece 2 or in a corresponding position of displacement, since the projections of the turrets holder-matrix 22, 23, which carry the parts of matrix 22.1, 22.2, 22.3, 22.4, 23.1, 23.2, 23.3 23.4, in mutual engagement in the manner of gears, must be passed along each other and along the position in which the workpiece is clamped. It is necessary here to pay attention to a corresponding servocontrol of the turrets holder matrix 22 and 23, so that they do not touch undesirably during a rotation.
    [0007] If this is not possible in one embodiment, or if a matrix change must take place between the dies 21 while a tube 4 is already in its working position 46, the turrets holder 22 and 22 23, if necessary, with a corresponding configuration of the set of dies 20, can also be moved into a displacement position (not shown here), whereas then, for example, at least one of the turret holders 22, 23 is axially movable in the direction of the axis of rotation 24, 25. Optionally, this can also be obtained by means of an overall displacement of one of the axes of rotation 24 or 25.
    [0008] With a corresponding configuration, it is also possible here that the two matrix turrets 22 and 23 or the two axes of rotation 24 and 25 are mounted in axial translation in the longitudinal extent of the press to be discharged, in a manner similar to the die frame relative to the advancing direction 41, or vice versa. While in FIG. 2, to form or close a die 21, the two die portions 22.1 and 23.1 are already in the pressing or pushing position 45 (see die portion 23.1) or shortly before this position (see matrix part 22.1), the other matrix parts 22.2, 22.3, 22.4 and 23.2, 23.3, 23.4 are arranged in provisioning positions 53 (referenced by way of example only). This gives a very fast matrix change.
    [0009] The variant of the rotary press 101 shown in cross-section in FIG. 3 has the same structure, with the exception of the other matrix-bearing turrets 122 and 123, which is essentially the same as the press 1 shown in FIGS. and 2, so that in order to avoid repetition, reference will be made to the above description with respect to construction and operation. For the same components, therefore, identical reference numerals have been used. The two matrix turrets 122 and 123 here also have bodies of revolution (not specifically referenced), which respectively form or carry only two die portions 122.1 and 122.2, respectively 123.1 and 123.2. The matrix portions 122.1, 123.1 and 122.2, 123.2 here can, by appropriate rotation of the matrix turrets 122 and 123, again form respectively a matrix 121 in the pressing position 45 or discharge. However, in this embodiment also, attention must be paid to a corresponding servocontrol of the die-holder turrets 122 and 123 so that they do not undesirably contact each other during rotation. The matrix portions 122.1 and 122.2 as well as 123.1 and 123.2 are respectively characterized by a counter-rotating arrangement or opening respectively towards one another. The two axes of rotation 24 and 25 of the two matrix turrets 122 and 123 are here vertically superimposed, and not horizontally juxtaposed. In a similar manner to the two presses 1 and 101 respectively shown in FIGS. 1 and 2 and in FIG. 3, the other pressing press 201 shown in cross-section in FIG. 4 is essentially characterized by the same structure - again with the exception of matrix turrets 222 and 223, of different configuration -. We will therefore refer to the description above. The matrix turrets 222 and 223 carry or form here two die portions 222.1 and 222.2, respectively 223.1 and 223.2; however, these matrix turrets 222 and 223 have a symmetrical structure of revolution, so that with regard to the opening and closing of the matrices 221 (referenced by way of example only), a servo-control is obtained. complex of the two matrix turrets 222 and 223 and the change of matrix is not possible during a heating, or is only possible in a position of displacement in which the turrets holder 222, 223 matrix are displaced and then shot in an appropriate manner. Similarly, the matrix turrets 222, 223, which are in themselves of a very simple structure, can not be simply turned in synchronism, but must be slaved in a complex way in order to be able to undertake a matrix change, unless, by means of at least one displacement position, they are separated from each other so that they can rotate independently of one another. In this embodiment also, the die portions 222.1, 223.1 and 222.2, 223.2, by appropriate rotation of the die holder turrets 222 and 223 in the pressing or discharge position 45, respectively form a die 221 again. The displacement position can for example be defined by an axial displacement of the two turret holders 22, 23, 122, 123, 222, 223 or only one of these turrets. Likewise, the displacement position can optionally be defined by the fact that the rotation axes 24, 25 are displaced radially, therefore perpendicularly to their extent, in order to avoid, in particular, mutual engagement of the matrix turrets 22, 23, 122, 123, 222, 223 during rotation. If complex rotational movements are possible, a distinct displacement position can be dispensed with.
    [0010] The presses to be discharged 1, 101 and 201 shown in FIGS. 1 to 4 all serve in particular to push the end of drill rods out. These repressing presses 1, 101 and 201 may thus also, in a preferred manner, be considered in particular as presses to discharge for drill rods.
