The sliding block 28 is fixedly connected to the outer side of the bottom end of the bottom plate 27. The second sliding groove 29 is arranged at the upper end of the workbench 11 on both sides.

[0031] The first sliding groove 21 is used for guiding the movable column 22. The movable column 22 is used for driving the second connecting rod 25 to move. The first connecting rod 23 is used for driving the movable column 22 to move. The first fixed column 24 is used for driving the first connecting rod 23 to move.

The bottom plate 27 is used for supporting the lower die 15. The sliding block 28 is used for supporting the bottom plate 27. The second sliding groove 29 is used for guiding the sliding block 28.

[0032] The bending assembly further comprises a hydraulic tank 13, an upper die 14 and a lower die 15. The hydraulic tank 13 is fixedly connected to the top end of the support frame 12. The upper die 14 is fixedly connected to the bottom end of the hydraulic tank 13. The lower die 15 is fixedly connected to the upper end of the bottom plate 27.

[0035] The first fixed column 24 can move up and down under the driving of the upper die 14. The movement of the first fixed column 24 through the first connecting rod 23 can drive the movable column 22 to slide along the inner part of the first sliding groove 21.

[0036] The first connecting rod 23 is located at the outer side of the second connecting rod 25. The sliding block 28 is slidingly connected to the inner position of the second sliding groove 29.

[0037] When the bottom plate 27 moves under the drive of the second fixed column 26, the sliding block 28 moves with the bottom plate 27 and drives the bottom plate 27 to move along the direction of the second sliding groove 29.

[0038] Working principle: when the metal piece is bent, the hydraulic tank 13 drives the upper die 14 to move downward, the first fixed column 24 is driven by the upper die 14 to move downward, the first connecting rod 23 is driven by the first fixed column 24 to move outward, the movable column 22 is driven by the first connecting rod 23 to move outward along the first sliding groove 21, the second connecting rod 25 is driven by the movable column 22 to move inward, the second fixed column 26 is driven by the second connecting rod 25 to move inward, and the bottom plate 27 is driven by the second fixed column 26 to move inward, so that the bottom plate 27 moves linearly under the limiting of the sliding block 28 and the second sliding groove 29, and the lower die 15 is driven by the bottom plate 27 to move inward to the position directly below the upper die 14 to bend the metal piece. When the bending is completed, the hydraulic tank 13 drives the upper die 14 to move upward, so that the movable assembly is reset. When the reset is completed, the bottom plate 27 drives the lower die 15 to move to the outside of the workbench 11, that is, to the position outside the lower side of the upper die 14, so that the operator can operate on the upper end of the lower die 15 while being located outside the lower side of the upper die 14.

[0039] Please refer to Figure 4 The embodiment is based on the above-mentioned embodiment, and further includes:

[0040] The linkage assembly includes a placing groove 31, a supporting shaft 32, a movable plate 33 and a torsional spring 34. The placing groove 31 is arranged on one side of the upper end of the workbench 11. The supporting shaft 32 is fixedly connected to one side of the inside of the placing groove 31. The movable plate 33 is sleeved on the outer surface of the supporting shaft 32. The torsional spring 34 is fixedly connected to both sides of the movable plate 33.

[0041] The placing groove 31 is used for placing the movable plate 33. The supporting shaft 32 is used for supporting and guiding the movable plate 33. The movable plate 33 is used for shielding the outside of the bottom plate 27 and the lower die 15. The torsional spring 34 is used for resetting the movable plate 33.

[0042] The movable plate 33 is located at one end of the inside of the second sliding groove 29, and the top end of the movable plate 33 is flush with the upper end of the workbench 11.

[0043] The movable plate 33 can rotate along the supporting shaft 32. When the movable plate 33 is flush with the workbench 11, the bottom plate 27 is located at the upper end of the movable plate 33.

[0044] The torsional spring 34 surrounds the outer surface of the supporting shaft 32, and the outer end of the torsional spring 34 is fixedly connected to the inside of the placing groove 31.

[0045] When the movable plate 33 is aligned with the workbench 11, the movable plate 33 drives the torsion spring 34 to deform and generate elastic force.

[0046] Working principle: when the bottom plate 27 drives the lower die 15 to move inward to bend the metal piece, the bottom plate 27 does not block the movable plate 33, and the movable plate 33 moves outward to be perpendicular to the workbench 11 under the elastic force of the torsion spring 34, at this time, the movable plate 33 can shield the outside of the bottom plate 27 and the lower die 15, avoiding the operator to move in the direction of the inside of the lower die 15, when the bending is completed, the bottom plate 27 drives the lower die 15 to exert a pushing force on the movable plate 33, so that the movable plate 33 rotates along the supporting shaft 32 to the inside of the placing groove 31, thereby operating the metal piece on the upper end of the lower die 15.

[0047] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications.
