[0002] Sheet metal refers to metal parts or products made through sheet metal processing technology. It is mainly formed by cutting, bending, stamping, welding and other processing methods on metal sheets. Sheet metal is widely used in modern manufacturing. Its flexibility and economy make it an indispensable part of industrial design. Sheet metal processing requires the use of processing equipment, and stamping equipment will be used in the stamping process to process sheet metal parts.

[0003] When the stamping equipment is working, the sheet metal to be processed needs to be placed on top of the stamping die, and then the stamping equipment is started. The stamping equipment will punch the sheet metal into shape. After stamping, the sheet metal parts need to be removed and a new sheet metal needs to be placed on top of the die to continue stamping.

[0004] However, when using existing stamping equipment, the processed sheet metal is placed on top of the mold manually. When placing the sheet metal manually, the sheet metal needs to be placed in the center of the mold to avoid the problem of unqualified products during stamping.

[0058] In the above embodiment, please refer to Figure 1 and Figure 2A limiting rod 10 is fixed on one side of the stamping equipment body 1, and an oblique rod 11 is fixed on the top of the limiting rod 10. The limiting rod 10, the oblique rod 11 and the stamping equipment body 1 form a triangular structure. A card slot 13 is provided at the bottom of the limiting rod 10. The limiting rod 10 can limit the end of the shift rod 74. The setting of the oblique rod 11 can make the limiting rod 10 bear the force better, and the limiting rod 10 will not be deformed.

[0059] When the present invention is in operation, the plate 17 is roughly laid flat on the top of the top rod 41, and then the hydraulic rod 2 is started. The hydraulic rod 2 drives the punching head 21 to move downward. When the punching head 21 moves downward, it drives the fixed rod 22 to move downward, thereby driving the first gear rod 23 and the second gear rod 24 to move downward. The first gear rod 23 slides on the inner wall of the first vertical groove 12, and the second gear rod 24 slides downward on the inner wall of the second vertical groove 18. When the first gear rod 23 slides downward, it drives the first gear 82 to rotate. When the first gear 82 rotates, it drives the third rotating rod 81 to rotate. When the third rotating rod 81 rotates, it drives the first pulley 83 to rotate. The rotation of the first pulley 83 will pass The first belt 85 drives the second pulley 86 to rotate. When the second pulley 86 rotates, it drives the input end of the speed change gear box 84 to rotate, so that the speed change gear box 84 drives the transmission rod 71 to rotate. When the transmission rod 71 rotates, it drives the sprocket 72 to rotate. When the sprocket 72 rotates, it drives the chain 73 to rotate. The chain 73 drives the shift rod 74 to move. The limit slider 75 at the end of the shift rod 74 slides on the inner wall of the slot 13. The shift rod 74 is slightly higher than the top of the cross plate 51. Therefore, the shift rod 74 does not contact the plate 17, and the punch head 21 continues to move downward. When the first toothed rod 23 is no longer in contact with the first gear 82, the shift rod 74 moves to the other end of the mold 3.

[0060] Then the punch head 21 continues to move downward by 5CM. At this time, the second gear rod 24 contacts the second gear 91, and the punch head 21 drives the second gear rod 24 to move downward. The second gear rod 24 drives the second gear 91 to rotate. The rotation of the second gear 91 drives the fourth rotating rod 9 to rotate. When the fourth rotating rod 9 rotates, it will drive the third pulley 92. The rotation of the third pulley 92 will drive the fourth pulley 93 to rotate through the second belt 94. When the fourth pulley 93 rotates, it drives the first rotating rod 6 to rotate. When the first rotating rod 6 rotates, it drives the first screw 62, the second screw 63 and the first bevel gear 64 to rotate at the same time. When the first bevel gear 64 rotates, it drives the third screw 62, the second screw 63 and the first bevel gear 64 engaged therewith. When the second bevel gear 65 rotates, the second bevel gear 65 drives the second rotating rod 61 to rotate. When the second rotating rod 61 rotates, it also drives the second screw 63 at its end to rotate. When the first screw 62 and the second screw 63 rotate at the same time, according to the screw principle, when the first screw 62 rotates, it drives the two sets of sliders 43 to slide to both sides. When the sliders 43 slide, they drive the ends of the connecting rods 42 to move. When one end of the connecting rod 42 moves, the other end will move downward. When the top plate 4 moves downward, it drives the ejector rod 41 to move downward. After the ejector rod 41 moves downward a certain distance, the bottom of the plate 17 contacts the top of the mold 3. At this time, the top plate 4 continues to move downward.

[0061] The rotation of the second screw 63 drives the clamping plate 5 to slide on the inner wall of the slide groove 31. When the clamping plate 5 moves, it drives the cross plate 51 to move. The four sets of cross plates 51 slide toward the middle of the mold 3 at the same time. Therefore, the cross plate 51 corrects the offset sheet 17 so that the sheet 17 is exactly in the center of the mold 3. When the second gear rod 24 is no longer in contact with the second gear 91, the first rotating rod 6 and the second rotating rod 61 stop rotating, and the punching head 21 continues to move downward by 5CM. At this time, the bottom of the punching head 21 contacts the top plate of the sheet, punching the sheet 17, and the sheet is squeezed into the punching groove 34 to form a sheet metal part.

[0062] Then the hydraulic rod 2 drives the punching head 21 to reset. At this time, the punching head 21 moves upward. When the second rack 24 contacts the second gear 91, it will drive the first rotating rod 6 and the second rotating rod 61 to reverse. When the first rotating rod 6 and the second rotating rod 61 rotate, they will drive the splint 5 to reset. The reversal of the first rotating rod 6 will drive the first screw 62 to reverse. The reversal of the first screw 62 will drive the slider 43 to move. When the slider 43 moves, it will drive the end of the connecting rod 42 to move. Therefore, the other end of the connection 42 will drive the top plate 4 to move upward. When the top plate 4 moves upward, it will drive the ejector rod 41 to slide on the inner wall of the top hole 33. The ejector rod 41 moves upward to eject the sheet metal part inside the stamping groove 34. When the second rack 24 is no longer in contact with the second gear 91, the first rotating rod 6 and the second rotating rod 61 stop rotating.

[0063] The punch head 21 continues to move upward. When the first gear rod 23 contacts the first gear 82, it will drive the third rotating rod 81 to reverse. When the third rotating rod 81 reverses, it will drive the transmission rod 71 to reverse. When the transmission rod 71 reverses, it will drive the lever 74 to reset. When the lever 74 resets, it will contact the sheet metal in its stroke. The lever 74 pushes the sheet metal to one side. Due to the arc-shaped setting of the top of the push rod 41, the sheet metal can reduce the friction between the push rod 41 when moving.
