    A shearing machine for severing parallel longitudinal members of grids or gratings has a horizontal guide-beam (9) which is stationary during the cut and upon which are provided counterbutts (17) in the manner of comb teeth; and a cutter-beam (10) which is movable parallel to and alongside the guide-beam during the cut and upon which blades (18) are provided in the manner of comb teeth, the blades cooperating with the counterbutts on the guide-beam to shear longitudinal members extending through notches (19,20) formed between adjacent counterbutts of the guide-beam and between adjacent blades of the cutter-beam. The guide-beam and the cutter-beam are guided in a machine frame for vertical movement into and out of a working position in engagement with a grid or grating and are associated for common motion in the vertical direction. Opposite to each of the two end faces of the guide-beam a respective stop-face (13,14) is provided; and opposite to each of the two end faces of the cutter-beam is arranged a respective single-acting fluid pressure-operated cylinder (5,6) which is fixed to the machine frame and has a piston (3,4 ) with a piston rod (15,16) formed at its end a thrust face for the respective end face of the cutter-beam for imparting to the cutter-beam a stroke parallel to the guide-beam and away from that cylinder to which fluid pressure is applied at that time.

    专利说明:

    The invention relates to the processing of metals by pressure, in particular to equipment for cutting, and can be used for cutting rods of gratings.
    Known scissors for cutting parallel longitudinal elements of the lattice containing a bed, a movable and a guide beam, of which the movable is mounted with the possibility of reciprocating movement by means of a power cylinder along the guide beam, and knives placed on the beam. The knives are placed on the traverses so that the longitudinal elements of the lattice are cut sequentially one after another one by one or in groups. This arrangement of knives reduces the “drive power [1].
    However, with this arrangement of knives, the quality of the cut worsens. Longitudinal elements, which are initially cut off under the influence of knives cutting them, are bent, since the elements are connected with the lattice elements that have not yet been cut. Since the knives take effect one after another, 5 then the deformation of the elements is different.
    In addition, it takes a lot of time to replace traverses with knives after they are blunt, which reduces the performance of the scissors.

    The disadvantage is the difficulty of changing knives when they are dull or when changing the size of the cut gratings. If necessary, you have to individually remove the knives and (or) replace them with new ones or rearrange them to other places along the traverse. This takes a lot of time, resulting in reduced productivity of scissors. Changing the traverse block with knives will require even more time than changing only knives.
    The purpose of the invention is to facilitate the change of traverses with knives.
    The goal is achieved in that scissors for cutting parallel longitudinal elements of the grating, mainly the grate, containing a bed, a movable and a guide beam, of which a movable beam is installed with the possibility of reciprocating movement along the guide beam, knives placed on both traverses at an equal distance from each other , the working power cylinder located at one end of the movable crosshead, and the knot installation unit in the working position in the form of a body and power cylinder, add They are provided with guides fixed on the bed and located parallel to the traverse on both sides, with stops placed coaxially to the ends of the traverse guide, an additional working cylinder mounted diametrically opposite to the working cylinder, and the rods of both working cylinders are aligned with the ends of the movable beam with it, and an additional power cylinder associated with the installation site of the knives in the working position, the body of which is made in the form of two connectors frames covering the ends of both traverses and connected to the power cylinders.

    The scissors contain a bed 1, a movable 2 and a guide 3 of the traverse, knives 4 and 5, placed on the traverses at an equal distance from each other, a working slave cylinder 6 and an additional working slider 7 installed diametrically opposite to each other from both ends of the movable beam 2 , stops 8 and 9, placed coaxially to the ends of the guide beam 3, guides 10 and 5 11, located parallel to the traverses 2 and 3 on both sides of them, and the node 12 for setting the knives in working position. The movable traverse 2 is installed with the possibility of reciprocating movement along the guide traverse 3 by interacting with the rods 13 and 14 of the working cylinders 6 and 7 mounted coaxially to the ends of the movable traverse 2. This arrangement of the rods allows the movable traverse 2 to move freely in the vertical direction. Knives 4 and 5 can be made in the form of combs 20 with cutting edges 15 and with troughs 16. The combs are rigidly connected with traverses 2 and 3 (Fig. 3 and 4). Each working power cylinder 6 and 7 is made in the form of a housing 17 ,. of the cover 25 18 and the piston 19 with the rod and is located on the base plate 20, mounted on the frame 1.

    The disadvantage is the difficulty of changing when they are blunt or when the dimensions of the gratings being cut are changed. If necessary, it is necessary to take out the knives separately and (or) to replace them with new ones or to move them to other places along the cross beams. This takes a lot of time, as a result of which the performance of the scissors decreases. Changing the traverse block with knives will require even more time than changing only knives. The purpose of the invention is to facilitate the traverse shift with knives. The goal is achieved by the fact that scissors for cutting parallel longitudinal lattice elements, mainly a grate, containing flat, movable and guiding crossbars, - from which the mobile cross bar is installed with the possibility of reciprocating movement along the guide bar, knives placed on both crossbars at equal distances from each other, the working power cylinder, located at one end of the movable cross member, and the knives installation unit in the working position in the form of the body and power cylinder, up to Locally fitted with guides fixed on the frame and parallel to the cross-arms of both sides, stops placed coaxially to the ends of the guide bar, an additional working power cylinder, installed diametrically opposite to the working power cylinder, and the rods of both working power cylinders arranged coaxially to the ends of the mobile beam with interoperability with it, and the additional power cylinder connected with the knives installation unit into the working position, the body of which is made in the form of two detachable framework covering both ends of the traverse and coupled to the actuators of Fig. 1 shows scissors, general view; in fig. 2 - the same, top view; figs, 3 and 4 - traverses with knives in two projections. The shears contain a bed 1, a movable 2 and a guide 3, traverses, knives t and 5, placed on traverses at an equal distance from each other, a working power cylinder 6 and an additional working power cylinder 7 installed diametrically opposed to each other at both ends of the movable traverse 2 stops 8 and 9, aligned coaxially with the ends of the guide bar 3, guides 10 and 11, parallel to the cross bars 2 and 3 on both their sides, and the unit 12 for setting the blades into working position. The mobile yoke 2 is installed with the possibility of reciprocating movement along the yoke 3 through interaction with the rods 13 and 14 of the working ram 6 and 7 mounted coaxially with the ends of the moving yoke 2. Such an arrangement of the rods allows the mobile yoke 2 to move freely in the vertical direction. The knives t and 5 can be made in the form of combs with cutting edges 15 and with hollows 16, Combs): they are firmly connected to the pulleys 2 and 3 (Fig. 3 and 4J. Each working power cylinder 6 and 7 is made in the form of body 17, The cover 13 and the piston 19 with the rod and is located on the base plate 20 mounted on the frame 1. The stops 8 and 9 are fixed on the covers 18 and prevent the guide yoke 3 from moving it in the longitudinal horizontal direction, not preventing its vertical movement. Guides 10 and 11 are fixed on frame 1. Assembly 12 for installing knives into working floor The housing is made in the form of a housing and power cylinders .1 and 22. The housing is made in the form of two detachable frames 23 and 2, covering the ends of the cross-arms 2 and 3. The split frame 23 is connected to the power cylinder 21, and the split frame 2h is connected to the additional power cylinder 22 The scissors work as follows. In the initial position, the cross members 2 and 3 are in the position. Above the crossbars 2 and 3, do not touch them, place the incoming grid in such a way that its longitudinal elements are located above the depressions 16. Then turn on the power cylinders 2 and 22, yoke 2 and 3 are raised and the longitudinal elements of the lattice are located in the valleys 16. Then one of the working power cylinders 6 or 7, for example 6, is turned on, and the rod 13 or T4, for example 13, interacting with the movement cross member 2 moves it along the guide bar 3 The movement of the mobile beam 2 relative to guide bar 3 takes place until all longitudinal lattice elements are cut. Then, the working ram cylinder, to which the movement of the traverse 2, for example, 7, moves, and its rod 14, interact with the movable traverse 2, moves it in the opposite direction, the section is again fed longitudinal lattice elements. The cutting edges 15 of the knives are loaded alternately when cutting. If the movable cross bar 2 has the number of knives or teeth of the combs one more than the guide cross bar 3, then the idle motion of the mobile bar is eliminated. The cross bars necessary for aligning the valleys 16 for laying the longitudinal lattice elements in them for changing the blades raise the cross bars 2 and 3, by means of the power cylinders 21 and 22, the frames 23 and 24 are easily separated and the block is removed, the cross member. Then insert a new traverse unit, connect frames 23 and 2 and the scissors are ready for use. Such an embodiment of the shears allows for a quick change of the knives, as a result of which their productivity is increased.
