Description

Technical Field

[0001] This utility model relates to the field of bending machines, and in particular to a mechanical compensation device for a bending machine worktable. Background Technology

[0002] Mechanical compensation for bending machines is a mechanical means of "pre-deformation to offset working deformation". It is the core solution to the elastic deformation problem in large and high-precision bending and is a key technology to ensure bending quality. In practical applications, hydraulic, mechanical or electric compensation schemes should be selected according to the type of bending machine and the requirements of the workpiece, and long-term stability should be ensured through regular maintenance.

[0003] The existing mechanical compensation devices for bending machines have a simple structure and the mechanical compensation process is not obvious, resulting in uneven pre-deformation, which greatly affects the bending accuracy and efficiency of the bending machine.

[0004] Therefore, it is necessary to provide a mechanical compensation device for the worktable of a bending machine to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model provides a mechanical compensation device for the worktable of a bending machine, which solves the problems of existing mechanical compensation devices for bending machines having a simple structure and an indistinct mechanical compensation process, resulting in uneven pre-deformation and greatly affecting the bending accuracy and efficiency of the bending machine.

[0006] To solve the above-mentioned technical problems, this utility model provides a mechanical compensation device for a bending machine workbench, including a workbench, a connecting seat fixed on the top of the workbench, a connecting platform slidably disposed on the connecting seat, a motor fixed on the connecting seat, and a threaded rod fixed on the output end of the motor, the threaded rod being threadedly connected to the connecting platform. A fixing plate is fixed on the connecting platform, an inclined block is fixed on the fixing plate, and a matching slider is slidably arranged on the inclined block. A connecting plate is fixed on the slider, and a lower mold is fixed on the connecting plate. A mold groove is provided on the lower mold. A top plate is fixed to the workbench via a connecting column. An upper mold is fixed to the bottom of the top plate via a hydraulic rod. A support frame is fixed to the connecting column, and the support frame is fixed to the lower mold via bolts.

[0007] Preferably, a stabilizing block is fixed on the workbench, and the stabilizing block is rotatably connected to one end of the threaded rod.

[0008] Preferably, the connecting seat is provided with a sliding groove adapted to the connecting platform.

[0009] Preferably, an operation box is provided on the workbench.

[0010] Preferably, a stop block is fixed to the bottom of the top plate, and the stop block is provided with a stabilizing groove that is compatible with the upper mold.

[0011] Preferably, a limiting rod is fixed at the bottom of the top plate, and a limiting groove adapted to the limiting rod is provided on the upper mold.

[0012] Compared with related technologies, the mechanical compensation device for the bending machine workbench provided by this utility model has the following beneficial effects: This utility model provides a mechanical compensation device for a bending machine worktable. By controlling a motor to drive a threaded rod to rotate, the connecting table moves, which in turn moves the inclined blocks on the fixed plate. Each inclined block has an inclined surface with a different angle, which applies different stresses to the corresponding sliders, causing the lower die on the connecting plate to undergo elastic pre-deformation of the material. This solves the problem that existing mechanical compensation devices for bending machines have a simple structure and the mechanical compensation process is not obvious, resulting in uneven pre-deformation, which greatly affects the bending accuracy and efficiency of the bending machine.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Please refer to the following: Figure 1-3 As shown, a mechanical compensation device for a bending machine workbench includes a workbench 1, a connecting seat 2 fixed on the top of the workbench 1, a connecting platform 3 slidably disposed on the connecting seat 2, a motor 4 fixed on the connecting seat 2, and a threaded rod 5 fixed to the output end of the motor 4, the threaded rod 5 being threadedly connected to the connecting platform 3. The present invention has a fixed plate 6 fixed on the connecting platform 3, a wedge 7 fixed on the fixed plate 6, and a matching slider 8 slidably arranged on the wedge 7. There are seven wedges 7, and the seven wedges 7 are provided with inclined surfaces at different angles. A connecting plate 9 is fixed on the slider 8, and a lower mold 10 is fixed on the connecting plate 9. The lower mold 10 is provided with a mold groove 11, and the workpiece is bent through the mold groove 11. The workbench 1 of this utility model is fixed with a top plate 13 by a connecting column 12. The bottom of the top plate 13 is fixed with an upper mold 15 by a hydraulic rod 14. A support frame 16 is fixed on the connecting column 12, and the support frame 16 is fixed with the lower mold 10 by bolts, so that the operation is stable. The workbench 1 of this utility model is fixed with a stabilizing block 17, and the stabilizing block 17 is rotatably connected to one end of the threaded rod 5. The connecting seat 2 is provided with a sliding groove that is compatible with the connecting table 3, which serves as a limit. The workbench 1 of this utility model is provided with an operation box 22, and a stop block 18 is fixed at the bottom of the top plate 13. The stop block 18 is provided with a stabilizing groove 19 that is compatible with the upper mold 15, which serves to limit the position. The bottom of the top plate 13 of this utility model is fixed with a limiting rod 20, and the upper mold 15 is provided with a limiting groove 21 that matches the limiting rod 20, so that the upper mold 15 can operate stably.
