[0027] As a technical optimization scheme of the utility model, by setting a rotating mechanism 10, when the workpiece is processed, the operator rotates the fixed screw 8 to drive the clamping mechanism 9 to no longer fix the workpiece, and the operator starts the brake motor 102, so that the output end of the brake motor 102 drives the driving tooth 103 to rotate, and then the rotating driving tooth 103 drives the driven tooth 101 to rotate, and then the rotating driven tooth 101 drives the movable rod 6 to rotate, so that the rotating movable rod 6 drives the mounting plate 7, the fixed screw 8 and the clamping mechanism 9 to rotate and move away from the current position, so as to avoid the clamping mechanism 9 affecting the normal operation of the discharge device 3.

[0028] refer to Figure 3 The limiting assembly 94 includes a limiting hole 941, which is opened on the front and rear sides of the top of the connecting block 91.

[0033] As a technical optimization solution of the utility model, by providing an anti-skid pad 12, the anti-skid pad 12 can increase the friction between the pressing plate 93 and the workpiece, thereby preventing the pressing plate 93 from slipping when pressing against a smooth workpiece surface.

[0034] refer to Figure 3 The top of the limiting rod 942 is fixedly connected with a truncated cone block 13.

[0035] As a technical optimization solution of the utility model, the truncated cone block 13 is provided to fix the truncated cone block 13 and the limiting rod 942, so that the truncated cone block 13 can limit the limiting rod 942 to avoid the limiting rod 942 from being separated from the limiting hole 941.

[0036] The working principle and use process of the utility model are as follows: when in use, the fixed screw 8 is away from the workpiece position, so that the operator places the workpiece on the inner side of the push block 2 and the bending block 4, and makes the workpiece and the bending block 4 stick together, and the operator starts the brake motor 102, so that the output end of the brake motor 102 drives the driving tooth 103 to rotate in the opposite direction, and then the rotating driving tooth 103 drives the driven tooth 101 to rotate, and then the rotating driven tooth 101 drives the movable rod 6 to rotate, so that the rotating movable rod 6 drives the mounting plate 7, the fixed screw 8, the connecting block 91, the spring 92, and the clamping plate 93 to rotate and move to the workpiece position, and then the operator rotates the fixed screw 8 in the forward direction, so that the fixed screw 8 drives the connecting block 91 to move, and while moving, the clamping plate 93 will first contact with the workpiece, and then the fixed screw 8 will be fixed to the workpiece. The fixed screw 8 drives the connecting block 91 to move downward continuously, so that the spring 92 is compressed through the connecting block 91, and the bottom of the spring 92 releases the pressure to the clamping plate 93, so that the clamping plate 93 clamps the workpiece through the compression force of the spring 92, thereby ensuring the stability of the processing, and then the operator starts the cylinder 1 to drive the push block 2 to move toward the workpiece, so that the push block 2 is bent through the bending block 4. After the bending is completed, the output end of the brake motor 102 drives the driving tooth 103 to rotate forward, and then the rotating driving tooth 103 drives the driven tooth 101 to rotate, and then the rotating driven tooth 101 drives the movable rod 6 to rotate, so that the rotating movable rod 6 drives the mounting plate 7, the fixed screw 8 and the clamping mechanism 9 to rotate and move away from the current position, so as to prevent the clamping plate 93 and other parts from affecting the normal operation of the discharge device 3.

[0037] To sum up: this bending device for metal product processing, by setting a movable rod 6, a mounting plate 7, a fixed screw 8, a clamping mechanism 9 and a rotating mechanism 10, when the workpiece needs to be bent, the fixed screw 8 drives the clamping mechanism 9 to clamp the workpiece to prevent the workpiece from shaking. When the bending is completed, the rotating mechanism 10 drives the movable rod 6 to rotate and drives the mounting plate 7, the fixed screw 8 and the clamping mechanism 9 to rotate and move away from the current position to prevent the clamping mechanism 9 from affecting the normal operation of the discharge device 3. This solves the problem that when the above-mentioned equipment is bent by the bending block, there is no structure for fixing the workpiece, and when the cylinder pushes the push block to bend the workpiece, displacement is likely to occur, resulting in inaccurate positioning. Moreover, the workpiece is not fixed, and when the push block pushes, one end will slightly tilt up, affecting the processing quality, and the increase in rework and scrap directly leads to the problem of increased production costs.
