Figure 5 shows a partial cycle of the sheet processed by the continuous folding mechanism. When the sheet is fed from the lower end of the continuous folding mechanism, it first passes between the upper die 5 and the lower die 6. When passing through the stamping mechanism, the sheet is first cut, stamped and flattened by the stamping mechanism. After the sheet is stamped into the shape of a battery connector, the connector is processed and stamped in sequence through a 45° bending step, a 90° bending step, a reverse 25° bending step, a reverse 45° bending step and a flattening and folding step. As the sheet moves and the upper die 5 moves up and down, the sheet can be processed accordingly. Finally, after the flattening and folding step is completed, the sheet can be cut and blanked, thereby completing the folding process of the battery connector. This design enables the sheet to be gradually folded during movement, thereby improving processing efficiency and reducing manual effort and labor output.

[0021] like Figure 3As shown, the lower ends of both sides of the punch 2 are fixedly connected with sleeve rods 7, and the upper ends of both sides of the blanking bracket 4 are fixedly connected with guide rods 8, and springs 9 are sleeved on the guide rods 8.

The end face of the stop block 20 is an inclined surface and is set corresponding to the product; the first pressing block 12 corresponds to the first positioning block 13. The sheet is first bent 45° by the first pressing block 12 and the first positioning block 13, and then moved to the lower end of the second pressing block 14 and bent 90° by the positioning limit of the second positioning block 15. The first guide roller 16 rotating at the end of the second positioning block 15 plays a rolling role, thereby improving the bending efficiency and avoiding damage to the sheet surface. , the sheet moves to the lower end of the third pressing block 19, the guide block 17 first contacts the third positioning block 18 slidingly set at the lower end, and then the third positioning block 18 pushes the sheet to be fixed against the block 20, and then the third pressing block 19 moves downward to bend the sheet in the opposite direction by 25 degrees. When the sheet moves to the lower end of the fourth pressing block 21, it is directly bent and pressed at 45 degrees in the opposite direction. When the sheet moves to the lower end of the fifth pressing block 22, the sheet is flattened by pressing at the right angle end, thereby completing the processing of the connecting piece, and then cutting and blanking are completed.
