Hydraulic lifting rods 2 are installed on both sides of the upper part of the base 1, and a workbench 3 is fixed above the hydraulic lifting rods 2. A bending assembly 6 is installed on the upper rear side of the base 1. The bending assembly 6 includes an upper frame 601, an electric telescopic rod 602 and a bending upper die 603. The electric telescopic rod 602 is installed on the lower front side of the upper frame 601, and the bending upper die 603 is fixed at the bottom of the electric telescopic rod 602; a bending lower die 5 is fixed in the middle of the workbench 3, and the position of the bending lower die 5 corresponds to that of the bending upper die 603;

[0021] The specific operation is as follows: the electric telescopic rod 602 is used to facilitate the lifting and adjustment of the height of the bending upper mold 603, and the hydraulic lifting rod 2 is used to facilitate the lifting and lowering of the workbench 3, thereby driving the lifting and lowering of the bending lower mold 5 and the metal sheet placed on its surface, so that the bending lower mold 5 cooperates with the bending upper mold 603 to bend the metal sheet, and different bending lower molds 5 and bending upper molds 603 can be replaced to perform different bending processes.

[0022] like Figure 1-Figure 2As shown, anti-bias limit assembly 4 is installed on the lower sides of both sides of the workbench 3, and the anti-bias limit assembly 4 includes a mounting frame 401, a drive motor 402, a bidirectional screw rod 403, a movable sleeve 404 and an outer mounting plate 405. The mounting frame 401 is fixedly connected to the workbench 3, and a drive motor 402 is installed on one side of the outer side of the mounting frame 401. A bidirectional screw rod 403 is rotatably arranged on the inner side of the mounting frame 401, and two movable sleeves 404 are symmetrically arranged on the outer side of the bidirectional screw rod 403. The upper side of the movable sleeve 404 is fixed with an outer mounting plate 405. The anti-bias limit assembly 4 also includes a fixed connecting plate 406, Sliding connecting plate 407 and limiting clamping plate 408, both sides of the outer mounting plate 405 are fixed with fixed connecting plates 406, and one side of the fixed connecting plate 406 is installed with sliding connecting plate 407, and one side of the sliding connecting plate 407 is fixed with limiting clamping plate 408; the sliding connecting plate 407 and the fixed connecting plate 406 are slidably connected, and the sliding connecting plate 407 and the fixed connecting plate 406 are fixed by bolts; the limiting clamping plate 408 and the outer mounting plate 405 are parallel to each other, and the limiting clamping plate 408 is located on the upper side of the workbench 3, and the limiting clamping plates 408 on the front and rear sides are symmetrically distributed about the transverse center line of the workbench 3;

[0023] The specific operation is as follows: the driving motor 402 is used to drive the rotation of the bidirectional screw rod 403, which can then drive the relative movement of the movable sleeve 404, the outer mounting plate 405 and the limit clamp 408 on the front and rear sides, so that the limit clamps 408 on the front and rear sides can limit the front and rear sides of the metal sheet on the workbench 3 and the bending lower mold 5 to prevent the workpiece from shifting and falling off during the bending process.

In this process, the driving motor 402 can be used to drive the rotation of the bidirectional screw rod 403, thereby driving the front and rear sides. The relative movement of the movable sleeve 404, the outer mounting plate 405 and the limiting clamping plate 408 enables the limiting clamping plates 408 on the front and rear sides to limit the front and rear sides of the metal sheet on the workbench 3 and the bending lower mold 5 to prevent the workpiece from shifting and falling off during the bending process. The connection position of the fixed connecting plate 406 and the sliding connecting plate 407 can be adjusted by sliding, and then the distance between the limiting clamping plate 408 and the outer mounting plate 405 can be adjusted by tightening the bolts to adjust the limitable range of the limiting clamping plate 408, thereby completing the use process of the anti-falling sheet metal bending equipment.
