[0025] In a specific application scenario, when stamping the stamping sheet 5, first place the lower die 418 above the stamping platform 2, and then start the winding motor 425.

At this time, the opposing slider 428 moves oppositely above the stamping platform 2, and the lower die 418 is clamped and fixed by the movable clamping seat 432 on the opening and closing rod 431 of the support arm 430. Then, the stamping sheet 5 is passed through the guide roller 403 and placed on the lower die 418. Start the hydraulic driver 3, and the hydraulic driver 3 drives the lifting tooling plate 433 to descend. At this time, the cutting pressure rod 416 on the upper die 410 is compressed, so that the cutting knife 417 on the cutting pressure rod 416 passes through the cutting groove 423 to cut the stamping sheet 5. At the same time, the upper die 410 continues to descend, and the lifting bending plate 422 descends, and the stamping sheet 5 is bent by the lifting bending plate 422. When the abutting column 420 below the lifting bending plate 422 descends to abut against the notch 419, at this time, the punching pressure rod 413 on the upper die 410 punches the bent stamping sheet 5. During the descent of the lifting tooling plate 433, the guide cylinder 407 slides in the limit circular tube 406, so as to perform stamping limit on the upper die 410 below the lifting tooling plate 433.

A same third telescopic spring 614 is fixedly connected between the sliding column 611 and one side of the limiting circular rod 610. One side of the sliding column 611 is respectively movably connected to a first U-shaped rod 612 and a second U-shaped rod 613. One side of one of the tooling blocks 602 is movably connected to an electric telescopic rod 609, and the driving end of the electric telescopic rod 609 is fixedly connected to one side of the first U-shaped rod 612. One side of the second U-shaped rod 613 is fixedly connected to a mounting rod 616.

An adjusting pressing plate 618 is movably connected to the outside of the two rotating shafts 617.

[0029] In a specific application scenario, after the lower die 418 is initially fixed, the electric telescopic rod 609 is started at this time. The electric telescopic rod 609 drives the sliding column 611 to slide on the outside of the limiting circular rod 610, so as to drive one end of the adjusting pressing plate 618 to press down through the mounting rod 616, so that the lower pressing clamping seat 619 provides a downward clamping force on the lower die 418. At the same time, the rotating column 605 on the clamping plate 608 moves oppositely on both sides of the lower die 418 through adaptive adjustment on the pressure rod 604 to form clamping. Through the stamping auxiliary module 6, by clamping different surfaces of the lower die 418, the stability of the lower die 418 during the stamping operation is improved.

[0030] It should be noted that the sliding column 611 slides on the outside of the limiting circular rod 610, and the rotating column 605 on the clamping plate 608 is stretched by the second telescopic spring 607 to perform adaptive angle adjustment on the pressure rod 604, so that the clamping plate 608 fits the outer wall of the lower die 418.

The hydraulic actuator 3 drives the lifting tooling plate 433 to descend. At this time, the cutting pressure rod 416 on the upper die 410 is compressed, so that the cutting knife 417 on the cutting pressure rod 416 passes through the cutting slot 423 to cut the stamping sheet 5. Step 3: At the same time, the upper die 410 continues to descend, and the lifting bending plate 422 descends. The stamping sheet 5 is bent by the lifting bending plate 422. When the abutting column 420 below the lifting bending plate 422 descends to abut against the notch 419, at this time, the punching pressure rod 413 on the upper die 410 punches the bent stamping sheet 5. During the descent of the lifting tooling plate 433, the guiding cylinder 407 slides in the limiting circular tube 406, so as to perform stamping limit on the upper die 410 below the lifting tooling plate 433. The ball 408 on the guiding cylinder 407 abuts against the inner wall of the limiting circular tube 406, thereby reducing the friction on the limiting circular tube 406.

10. A method of using an apparatus for one-time stamping of a busbar connection bar, using an apparatus for one-time stamping of a busbar connection bar according to claim 9, characterized in that, It includes the following steps: Step 1: When stamping the stamping sheet (5), the lower die (418) is clamped and fixed by the movable clamping seat (432) on the opening and closing rod (431) of the support arm (430), and then the stamping sheet (5) is passed through the guide roller (403) and placed on the lower die (418). Step 2: Start the hydraulic driver (3), and the hydraulic driver (3) drives the lifting tooling plate (433) to descend. At this time, the cutting pressing rod (416) on the upper die (410) is compressed, so that the cutting knife (417) on the cutting pressing rod (416) passes through the cutting groove (423) to cut the stamping sheet (5). Step 3: At the same time, the upper die (410) continues to descend, and the lifting bending plate (422) descends. The stamping sheet (5) is bent by the lifting bending plate (422). When the abutting column (420) below the lifting bending plate (422) descends to abut against the notch (419), at this time, the punching pressing rod (413) on the upper die (410) punches the bent stamping sheet (5). Step 4: During the descent of the lifting tooling plate (433), the guiding cylinder (407) slides within the limiting circular tube (406), thereby performing stamping limit on the upper die (410) below the lifting tooling plate (433). The ball (408) on the guiding cylinder (407) abuts against the inner wall of the limiting circular tube (406), thereby reducing the friction on the limiting circular tube (406).
