[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-Figure 4 The shearing machine's pushing mechanism provides two technical solutions:

[0025] The first embodiment includes a workbench 1 and a shearing machine body 2. A stable pushing mechanism is provided above the workbench 1. The stable pushing mechanism includes:

[0026] The pressing assembly 4 is used to press down the upper surface of the plate. The pressing assembly 4 includes two left and right fixed seats 41, and the two fixed seats 41 are fixedly connected to the top of the workbench 1. An intermediate rod 42 is rotatably connected between the opposite sides of the two fixed seats 41. A plurality of extension plates 43 are fixedly connected to the surface of the intermediate rod 42 at equal distances. A roller 44 is rotatably connected to one side of the extension plate 43. The intermediate rod 42 passes through the right fixed seat 41 and extends to one end on the right side of the fixed seat 41 and is fixedly connected to a swing rod 45. The right side of the swing rod 45 is rotatably connected to the first T-block 4 6. The right side of the workbench 1 is rotatably connected to the second T-block 47, and a limit spring 48 is fixedly connected between the first T-block 46 and the opposite side of the second T-block 47. The intermediate rod 42 passes through the left fixed seat 41 and extends to one end on the left side of the fixed seat 41 and is fixedly connected to a fixed block 49. An arc-shaped groove 410 is provided inside the fixed block 49. The left side of the workbench 1 is rotatably connected to the second hydraulic cylinder 411, and the telescopic end of the second hydraulic cylinder 411 is fixedly connected to an L-shaped rod 412, and the bent part of the L-shaped rod 412 is located inside the arc-shaped groove 410.

[0027] When pushing the plate, the plate is pressed down by the pressing component 4, thereby ensuring the stability of the plate during movement, and when shearing the plate, the roller 44 is pressed against the plate by starting the second hydraulic cylinder 411, thereby ensuring the stability of the plate during shearing, thereby improving the practicality of the device when used.

[0028] The second embodiment is mainly different from the first embodiment in that: the pushing component 3 is used to push the plate and clamp the plate for centering. The pushing component 3 includes two left and right slide grooves 31 opened on the top of the workbench 1. The inner surfaces of the two slide grooves 31 are slidably connected to the U-shaped plate 32 through sliders. The right side of the U-shaped plate 32 is fixedly connected to the driving motor 33. The output end of the driving motor 33 is fixedly connected to a bidirectional threaded rod 34, and the other end of the bidirectional threaded rod 34 is rotatably connected to the left side of the inner wall of the U-shaped plate 32. The surface of the bidirectional threaded rod 34 is threadedly connected to two left and right T-shaped plates 35, and the T-shaped plate 35 is slidably connected to the front of the inner wall of the U-shaped plate 32. The top of the workbench 1 is fixedly connected to a first hydraulic cylinder 36, and the telescopic end of the first hydraulic cylinder 36 is fixedly connected to the front of the U-shaped plate 32.

[0029] Before pushing the plate, the driving motor 33 is started to rotate the bidirectional threaded rod 34, so that the two T-plates 35 clamp and center the plate, ensuring the accuracy of the position of the plate when entering the shearing machine.

[0030] When in use, the plate is placed on the top of the workbench 1, and the drive motor 33 is started to rotate the bidirectional threaded rod 34. The rotation of the bidirectional threaded rod 34 causes the two T-shaped plates 35 to approach each other. The T-shaped plates 35 approach each other and clamp on both sides of the plate, thereby aligning the position of the plate. Then the first hydraulic cylinder 36 is started to move the U-shaped plate 32, and then the plate is pushed through the T-shaped plate 35, and the plate enters under the roller 44, causing the intermediate rod 42 to rotate. The intermediate rod 42 rotates and compresses the limit spring 48, so that the roller 44 maintains a contact and downward pressure relationship with the plate through the elastic force of the limit spring 48. When the plate is moved to the shearing machine body 2 for shearing, the second hydraulic cylinder 411 is started to move the L-shaped rod 412, and when the L-shaped rod 412 contacts the tail of the arc groove 410, the fixed block 49 is rotated, thereby driving the intermediate rod 42 to rotate, so that multiple rollers 44 are pressed tightly against the top of the plate, thereby ensuring the stability of the plate during shearing.
