In the idle stage, the driving cylinder at the top inner side of the bending machine body 1 drives the guide rod 205 inside the traction bracket 204 to drive the guide sleeve 206 to move, and the guide sleeve 206 drives the adjusting slide 207 to move forward. The guide slide 208 on the adjusting slide 207 moves outside the two movable parts 202, and the cleaning teeth 209 of appropriate specifications at the bottom of the adjusting slide 207 match the bending slot on the lower die 1010. The driving motor on one side of the bending machine body 1 drives the rotating screw 2 2 to rotate, and the outer end of the rotating screw 2 2 drives the rotating screw 3 201 to rotate synchronously through the pulley. The rotating screw 2 2 and the rotating screw 3 201 respectively drive the movable part 202 to move, and the limiting bumps at both ends of the movable part 202 drive the adjusting slide 207 to move horizontally. The cleaning teeth 209 at the bottom of the adjusting slide 207 are slidably installed in the bending slot on the lower die 1010 to scrape and clean the extruded impurities to ensure the bending accuracy of the stainless steel plate.
