By setting the spring 204, when a new component needs to be replaced for positioning and clamping, the positioning plate 205 is pulled backward, and the new component is placed between the positioning plate 205 and the rectangular plate 203, and the positioning plate 205 is released. Under the action of the spring 204, the positioning plate 205 will automatically position and clamp the new component. A positioning plate 205 is installed at one end of the spring 204. By setting the positioning plate 205, the positioning plate 205 is mainly used to position and clamp the component. A limiting plate 206 is installed at the top of the bottom plate 1 on the rear surface of the bending mold 101. By setting the limiting plate 206, the limiting plate 206 is mainly used to support the rear surface of the component.

[0020] Specifically, a pressure plate 3 is installed in the inner cavity of the rectangular plate 203 outside the spring 204, a screw 301 is installed at one end of the pressure plate 3, and a knob 302 is installed at one end of the screw 301. By setting the knob 302, the knob 302 can be rotated when positioning and clamping the parts. The rotation of the knob 302 drives the screw 301 to rotate, and the rotation of the screw 301 drives the pressure plate 3 to move and squeeze the surface of the positioning plate 205 to fine-tune the clamping degree of the positioning plate 205.

[0021] Furthermore, a limiting column 4 is installed in the inner cavity of the rectangular plate 203 outside the pressure plate 3, and one end of the limiting column 4 is connected to the surface of the positioning plate 205. By setting the limiting column 4, the limiting column 4 is mainly used to guide the positioning plate 205 and improve the stability of the positioning plate 205.

[0023] Furthermore, the rear surface of the positioning plate 205 and the surface of the limiting plate 206 are both installed with an anti-skid plate 6. By setting the anti-skid plate 6, the anti-skid plate 6 is mainly used to play an anti-skid role when positioning and clamping parts.

[0024] Furthermore, a plurality of connecting plates 7 are installed on both sides of the base plate 1. By providing the connecting plates 7, the inner cavity of the connecting plates 7 is mainly used for installing bolts for fixing the base plate 1.

[0025] The method of using this embodiment is as follows: first, place the part to be processed on the top of the bending mold 101, and make the rear surface of the part to be processed flat with the surface of the limit plate 206, then rotate the rocker 5, the rocker 5 drives the threaded rod 201 to rotate, thereby driving the sliding block 202, the rectangular plate 203 and the positioning plate 205 to move, so that the surface of the positioning plate 205 squeezes the surface of the part to be processed and performs positioning clamping, and at the same time, the knob 302 can be rotated, the rotation of the knob 302 drives the screw 301 to rotate, and the rotation of the screw 301 drives the pressing plate 3 to move and squeeze the surface of the positioning plate 205, thereby adjusting the clamping degree of the positioning plate 205. The degree of processing is fine-tuned. At this time, the bending knife is used to squeeze the part to be processed so that the part enters the inner cavity of the bending mold 101, thereby bending the part. After the bent part is taken out, when a new part to be processed needs to be installed, the positioning plate 205 is pulled backward, and the new part is placed between the positioning plate 205 and the rectangular plate 203, and the positioning plate 205 is released. Under the action of the spring 204, the positioning plate 205 will automatically position and clamp the new part to be processed, so there is no need to move the rectangular plate 203 and the positioning plate 205 as a whole before positioning and clamping the new part to be processed.
