Through the synergistic effect of the first positioning member 30 and the second positioning member 40, the punching die can continuously punch and position the sheet metal part 60 in a two-dimensional space. This design improves the production efficiency and punching accuracy of the sheet metal part 60, while reducing the skill requirements for the operator. In addition, the punching die has a simple structure and low processing cost.

[0025] It should be further explained that the first positioning member 30 and the second positioning member 40 can be moved by manual drive or electric drive. In a specific embodiment, the first positioning member 30 and the second positioning member 40 are both controlled by servo motor drive, and the operator can input instructions through the digital display screen, and the system will control the moving distance of the first positioning member 30 in the second direction and the moving distance of the second positioning member 40 in the first direction to achieve more accurate positioning.

When an external force is applied to make the slider 41 slide in the slide groove 31, the second positioning member 40 will move along with the slider 41 along the first direction, thereby realizing continuous punching and positioning of the sheet metal part 60 in the first direction.

[0027] In a specific embodiment, the slide groove 31 is designed as a T-shaped groove, which has good load-bearing capacity and sliding stability.

[0028] In some optional embodiments, the second positioning member 40 is provided with a moving member 42, and the moving member 42 is arranged on the same side as the slider 41, and the lower surface of the moving member 42 is pressed against the top of the first positioning member 30, and the first positioning member 30 is provided with a first scale, and the moving member 42 is provided with a second scale, and the configuration of the first scale and the second scale forms a vernier caliper structure. Specifically, the first scale and the second scale are arranged relative to each other, the first scale is a millimeter scale, and the second scale is a subdivision scale, and the second scale is finer than the first scale. Exemplarily, the interval between two adjacent scale lines of the first scale is 1 mm, and the 10 scale lines on the second scale correspond to 1 mm of the first scale. In this embodiment, through the setting of the vernier caliper structure, the second positioning member 40 is more accurately positioned, the processing error is effectively reduced, the accuracy of punching is improved, and the quality of the final product is ensured.

[0029] In some optional embodiments, when the moving member 42 moves to the target position, the moving member 42 is fastened to the first positioning member 30 by a screw. Specifically, a limit hole is provided on the moving member 42. When the moving member 42 reaches the target position, the operator can tighten the screw into the limit hole, thereby fastening the moving member 42 to the first positioning member 30, so that the second positioning member 40 limits the position of the sheet metal part 60 in the first direction. The target position refers to a specific position that the moving member 42 needs to reach during the adjustment process. This specific position ensures that the position to be punched of the sheet metal part 60 is accurately aligned with the punching opening of the punching die 20.
