Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0032] An embodiment of the present utility model provides a lower die device 100, which is applied to a bending machine 1000. As Figures 1 to 3 shown, the bending machine 1000 includes a frame body 200 and a lower die holder 300. The lower die holder 300 can be connected to the frame body 200, and the lower die device 100 can be arranged on the frame body 200, specifically, it can be arranged on one side of the frame body 200 (that is, one end of the frame body 200 in the left-right direction). The lower die device 100 includes an adjustment component 20 and a driving component 10. The adjustment component 20 can be connected to the lower die holder 300, specifically, the adjustment component 20 is connected to the end of the lower die holder 300. The driving component 10 can be connected to the adjustment component 20, and the driving component 10 is used to drive the adjustment component 20 to move, so that when the adjustment component 20 moves, it can drive the lower die holder 300 to move along the front-back direction of the frame body 200.

[0033] It can be understood that the working principle of the lower die device 100 is generally as follows:

[0034] When it is necessary to replace the lower die part 34, the driving component 10 drives the adjustment component 20 to move, so that the adjustment component 20 moves and drives the lower die holder 300 to move away from the frame body 200, so that the operator can conveniently and safely replace the lower die part 34.

[0035] When the lower die part 34 is replaced and the workpiece is ready to be processed, the driving component 10 drives the adjustment component 20 to move, so that the adjustment component 20 moves and drives the lower die holder 300 to move towards the frame body 200, so as to start bending the workpiece.

[0036] In summary, compared with the prior art, the lower die device 100 has at least the following beneficial effects:

[0037] When the driving component 10 of the lower die device 100 drives the adjustment component 20 to move, the adjustment component 20 moves and can drive the lower die holder 300 to move along the front-back direction of the frame body 200, so that when the lower die holder 300 moves away from the frame body 200, the disassembly and installation of the lower die part 34 can be conveniently and quickly completed. This not only simplifies the operation process, improves the replacement efficiency, optimizes production, but also reduces the risk factors brought by the operator during the replacement of the lower die part 34.

[0038] To enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0039] In some embodiments, as Figure 2 shown, the lower die device 100 further includes a first outer cover 31 and a second outer cover 32, and the second outer cover 32 can be disposed on the first outer cover 31. At least part of the driving assembly 10 can be disposed in the first outer cover 31, and the adjusting assembly 20 can be disposed in the second outer cover 32.

[0040] In some embodiments, as Figure 2 shown, the driving assembly 10 includes a driving motor 11, a driving wheel 12, a driven wheel 13, and a transmission belt 14. The driving motor 11 can be disposed in the first outer cover 31. The driving motor 11 can be connected to the driving wheel 12, the driving wheel 12 and the driven wheel 13 can be drivingly connected through the transmission belt 14, and the driven wheel 13 can be connected to the adjusting assembly 20. It can be understood that the driving motor 11 can drive the driving wheel 12 to rotate, the driving wheel 12 drives the driven wheel 13 to rotate through the transmission belt 14, and the rotation of the driven wheel 13 drives the adjusting assembly 20 to move.

[0041] In some embodiments, as Figure 2 shown, the driving assembly 10 further includes a reduction motor 15. The reduction motor 15 can be disposed in the first outer cover 31, and the reduction motor 15 can be disposed between the driving motor 11 and the driving wheel 12 to reduce the rotation speed of the driving motor 11 while increasing the output torque.

[0042] In some embodiments, as Figure 2 shown, the lower die device 100 further includes a third outer cover 33. The third outer cover 33 can be disposed close to the first outer cover 31 and the second outer cover 32. The driving wheel 12, the driven wheel 13, and the transmission belt 14 can all be disposed in the third outer cover 33.

[0043] In some embodiments, as Figure 2 shown, the adjusting assembly 20 includes a ball screw 21, a screw nut seat 22, and a screw push block 23. One end of the ball screw 21 can be fixedly connected to the driven wheel 13, and the other end can pass through part of the screw push block 23. The screw push block 23 can be fixedly connected to the screw nut seat 22, and the screw push block 23 can be used to connect to the lower die holder 300. The ball screw 21 can pass through the screw nut seat 22 and be rotatably connected to the screw nut seat 22 so that when the ball screw 21 rotates, it can drive the screw nut seat 22 to move along the axial direction of the ball screw 21.

[0044] Understandably, the axial direction of the ball screw 21 is consistent with the front and rear directions of the frame body 200. When the ball screw 21 rotates, the screw nut seat 22 and the screw pusher block 23 fixedly connected to the screw nut seat 22 move along the axial direction of the ball screw 21, thereby driving the lower die holder 300 connected to the screw pusher block 23 to move along the front and rear directions of the frame body 200. Specifically, when the ball screw 21 rotates forward, the lower die holder 300 moves in the direction approaching the frame body 200; when the ball screw 21 rotates reversely, the lower die holder 300 moves in the direction away from the frame body 200. Vice versa.

[0045] In some embodiments, as Figure 2 shown, the adjusting assembly 20 further includes a guide rail 24 and a guide block 25 both located in the second outer cover 32. The guide block 25 is slidably connected to the guide rail 24. The guide rail 24 can be disposed on the first outer cover 31, and the length direction of the guide rail 24 is consistent with the front and rear directions of the frame body 200. The screw nut seat 22 is fixedly connected to the guide block 25. The cooperation between the guide rail 24 and the guide block 25 improves the accuracy and stability of the movement of the lower die holder 300 in the front and rear directions of the frame body 200.

[0046] In some embodiments, as Figure 2 shown, the adjusting assembly 20 further includes a bearing 26 and a bearing seat 27 both located in the second outer cover 32. The bearing 26 is connected to the bearing seat 27. The bearing 26 is fixed to the ball screw 21 and is disposed close to the driven wheel 13. The bearing seat 27 is disposed on the first outer cover 31.

[0047] In some embodiments, the first outer cover 31 and / or the second outer cover 32 may be provided with a connecting member (not shown in the figure) for mounting the lower die device 100 on the frame body 200. Optionally, the connecting member may be disposed on the first outer cover 31; or, the connecting member may be disposed on the second outer cover 32; or, the connecting member may be disposed on both the first outer cover 31 and the second outer cover 32 at the same time.

[0048] Based on the above lower die device, an embodiment of the present invention further provides a bending machine 1000, including a frame body 200 and a lower die holder 300 connected to the frame body 200. The bending machine 1000 further includes at least one of the above lower die devices 100, and the lower die device 100 is fixed to the frame body 200 and connected to the lower die holder 300.
