[0046] In a specific application scenario, when stamping the stamping sheet 5, the lower die 418 is first placed above the stamping platform 2, and then the winding motor 425 is started, and the winding rope 427 is wound by the winding disk 426 on the winding motor 425.

[0055] Step 2: Start the hydraulic driver 3, which drives the lifting tooling plate 433 to descend. At this time, the cutting pressure rod 416 on the upper mold 410 is compressed, so that the cutting blade 417 on the cutting pressure rod 416 passes through the cutting groove 423 to cut the stamped sheet 5;

[0056] Step 3: At the same time, the upper mold 410 continues to descend, and the lifting bending plate 422 descends, and the stamping plate 5 is bent by the lifting bending plate 422. When the support column 420 below the lifting bending plate 422 descends to abut against the notch 419, the punching pressure rod 413 on the upper mold 410 punches the bent stamping plate 5;

[0057] Step 4. During the descent of the lifting tooling plate 433, the guide cylinder 407 slides in the limiting circular tube 406, thereby stamping and limiting the upper mold 410 below the lifting tooling plate 433. The ball 408 on the guide cylinder 407 abuts against the inner wall of the limiting circular tube 406, thereby reducing the friction on the limiting circular tube 406.

Positioning columns are slidably connected to the inside of the two smooth holes. One end of the two positioning columns is fixedly connected to a tooling frame. One side of the two tooling frames is movably connected to a guide roller. The positioning column and the opposite side of the support rod are fixedly connected with the same telescopic spring. A stamping plate is placed on the lower mold, and the stamping plate passes through the guide roller.

6. The one-step stamping and forming equipment for bus duct connection bars according to claim 1, characterized in that: One side of the limiting round rod is fixedly connected to the second tooling block, and the second tooling block and one side of the installation rod are both connected to a rotating shaft through a bearing, and the adjusting pressure plate is movably connected to the outside of the two rotating shafts.

7. The one-step stamping and forming equipment for bus duct connection bars according to claim 6, characterized in that: A conveying support rod is fixedly connected to one side of the stamping platform, and a conveying roller is provided on the conveying support rod.

8. A method for using a busbar duct connection bar one-step stamping and forming device, using the busbar duct connection bar one-step stamping and forming device according to claim 7, characterized in that: The steps include: Step 1: When stamping the stamping sheet, the lower mold is clamped and fixed by the movable clamping seat on the opening and closing rod on the support arm, and then the stamping sheet is passed through the guide roller and placed on the lower mold; Step 2: Start the hydraulic drive, which drives the lifting tooling plate to descend. At this time, the cutting pressure rod on the upper mold is compressed, so that the cutting blade on the cutting pressure rod passes through the cutting groove to cut the stamped sheet; Step 3: At the same time, the upper mold continues to descend, and the lifting bending plate descends, and the stamping plate is bent by the lifting bending plate. When the support column below the lifting bending plate descends to abut against the notch, the punching pressure rod on the upper mold punches the bent stamping plate; Step 4: During the descent of the lifting tooling plate, the guide cylinder slides in the limiting circular tube, thereby stamping and limiting the upper mold below the lifting tooling plate. The balls on the guide cylinder abut against the inner wall of the limiting circular tube, thereby reducing the friction on the limiting circular tube.
