When the bottom mold 31 moves, the positioning slide groove 32 cooperates with the stabilizing bar 39 to improve the stability of the bottom mold 31 when moving. The structural design of the guide block 34 can guide debris to move to the waste channel 2 while blocking the slide groove 11.

[0038] After completing the first step of stamping, the plate enters the bending groove 14. During this process, another set of hydraulic cylinders is started to drive the folding top block 81 to operate. During the lifting process, the pressure block 84 first cooperates with the middle block 23 to limit the plate, and then the hydraulic cylinder continues to move downward, cooperating with the limit column 82 and the No. 3 spring 83 provided in the groove. The limit column 82 slides in the limit groove 85, and the No. 3 spring 83 plays a buffering role. During this downward movement, the folding block 86 at the bottom of the folding top block 81 continues to move downward to bend the plate, so that the plate is transformed from a straight shape to a U shape. After completion, the hydraulic cylinder here is reset to start the motors of the grinding assembly 40 and the cleaning assembly 50.

[0039] In the process of the folding top block 81 moving downward, the folding top block 81 is provided with an extension block on the outer wall. The extension block first presses the block 84 against the lifting rack 49, and the lifting rack 49 moves downward in the contraction groove 18 and squeezes the telescopic rod 48. The teeth on the lifting rack 49 mesh with the second gear 47, driving the second gear 47 to rotate. The rotating second gear 47 drives the coaxial first gear 46 to rotate. Then the rotating first gear 46 drives the slide bar 42 to move outward through the ring teeth on the outer wall of the slide bar 42. 42 moves in the circular groove 171 of the grinding groove 17. This process causes the grinding block 41 at the end of the slide rod 42 to leave a certain distance from the plate (the slide rod 42 slides on the limiting drive rod 45 through the limiting slide groove 43 and squeezes the No. 1 spring 44 located in the limiting slide groove 43). Therefore, after the folding top block 81 is reset, this section of the structure is automatically reset under the action of the telescopic rod 48, so that the grinding block 41 is re-attached to the teeth of the plate, and then the motor is started. During the conveying process of the plate, the teeth are polished.

[0040] The motor of the grinding assembly 40 is started, driving the synchronous wheel 57 to rotate. The rotating synchronous wheel 57 drives another set of synchronous wheels 57 to rotate through the synchronous belt 58. Then the two sets of rotating synchronous wheels 57 drive two sets of No. 1 worm gears 56 to rotate. The two sets of threaded segments with opposite rotation directions on the No. 1 worm gear 56 drive two sets of No. 1 worm wheels 55 to rotate. The rotating No. 1 worm wheel 55 drives the coaxial rotating rod 54 to rotate in the through hole 5 and the placement hole 4. The top surface of the rotating rod 54 is provided with a connecting seat 53. The connecting seat 53 cooperates with the hexagonal block at the bottom of the rotating rod 52 through the hexagonal groove on the top, driving the rotating rod 52 to rotate in the through hole 15. The rotating rotating rod 52 cleans the bent plate through the cleaning member 51 provided on the top.

[0041] After completing the bending task of the previous step, the teeth of the plate pass through the aisle 20 and enter the folding groove 19, and then the motor of the inner folding component 60 is started. The motor drives the No. 4 bevel gear 66 in the driving groove 22 to rotate, and the rotating No. 4 bevel gear 66 drives the No. 3 bevel gear 65 meshing therewith to rotate, so that the coaxially arranged synchronization rod 63 rotates in the driving groove 22, and the rotating synchronization rod 63 rotates through the two coaxially arranged No. 2 worm gears 64, driving the No. 2 worm gear 62 meshing therewith to rotate, and the rotating No. 2 worm gear 62 drives the coaxial inner folding part 61 to rotate in the folding groove 19, and the teeth of the plate are folded inwardly. Through the structure of the support beam 74, the teeth of the plate can be easily folded inwardly by the inner folding part 61. During this process, the pressure strip block 70 moves downward with the cooperation of the No. 2 spring 72 and the adjusting bolt 73, and the pressure strip block 70 cooperates with the support beam 74 to fix the plate to avoid shaking of the plate when the teeth of the plate are folded inwardly.
