[0002] Stamping dies are essential process equipment for stamping production and are technology-intensive products. The quality, production efficiency and production cost of stamping dies are directly related to the design and manufacturing of stamping dies. The level of stamping die manufacturing and design is one of the important indicators to measure the level of a country's product manufacturing industry, and to a large extent determines the new product development capabilities and product quality and benefits.

[0003] When the existing side-push stamping die is used, it can generally only realize one process for the workpiece during the stamping process. When some special workpieces are bent, they are usually sent to the next process to remove the excess edge material, which has low work efficiency. Therefore, it is urgent to design a side-push stamping die to solve the above problems. Utility Model Content

When the pressing plate 2 moves downward with the fixing piece 6, the moving piece 10 contacts the oblique extrusion piece 15 when it moves to a certain extent, and the punching plate 13 bends the workpiece when passing through the oblique extrusion piece 15, and the edge material is cut off through the cutter 11 after bending, which effectively reduces the process of the workpiece and improves the work efficiency.

[0024] The utility model provides a side-push stamping forming die, through the slide groove 7 on the fixed part 6, so that the moving part 10 cooperates with the oblique extrusion part 15 when descending, so that the stamping plate 13 bends the workpiece. When the bending reaches a certain degree, the fixed block 6 continues to press down to make the cutter 11 cut off the excess material of the workpiece, which effectively reduces the process of the workpiece and improves the work efficiency.

[0025] In an embodiment provided by the utility model, a slide groove 7 is provided on the lower surface of the fixing member 6, and a slider 8 is provided inside the slide groove 7, a first spring 9 is fixedly connected to the outer surface of one side of the slider 8, one end of the first spring 9 is fixedly connected to the slider 8, and the other end is fixedly connected to the inner wall of one side of the slide groove 7, the slider 8 is adapted to the slide groove 7, and the slider 8 can slide inside the slide groove 7.

[0026] In another embodiment provided by the utility model, the slider 8 is a convex structure, and the protruding end of the slider 8 is fixedly connected to the moving member 10. The moving member 10 is slidably connected to the fixed member 6 through the slider 8, and the moving member 10 can be moved along the slide groove 7 through the slider 8.

The cutter 11 can be maintained and replaced through the groove on the movable part 11, avoiding the need to replace the entire mold due to damage of the cutter 11, and also avoiding waste of resources.

[0028] In an embodiment provided by the utility model, a square groove is opened in the middle of the die 16, and two hollow rods 17 are fixedly connected inside the square groove, guide rods 18 are movably inserted inside the two hollow rods 17, and a second spring 22 is arranged between the two guide rods 18, one end of the second spring 22 is fixedly connected to the inner wall of the square groove, and the other end of the second spring 22 is fixedly connected to a support plate 19, the guide rod 18 can move inside the hollow rod 17, the support plate 19 is adapted to the square groove, and a part of the support plate 19 extends out of the square groove, and the support plate 19 is supported by the second spring 22.

The friction between the guide sleeves 20 and the guide pillars 21 is relatively large. During the continuous operation of the mold, the guide pillars 21 will be severely worn, resulting in damage to the mold. The guide sleeves 20 play a role in protecting the guide pillars 21 and reducing wear, thereby extending the service life of the mold.

[0030] Working principle: The die handle 3 cooperates with the upper die seat 1 to make the pressure plate 2 move downward. When the punch 5 contacts the workpiece on the punch 14, the first elastic element 4 continues to extrude the workpiece to ensure that the workpiece does not shake. At the same time, when pressing down, the moving part 10 cooperates with the oblique extrusion part 15 to make the moving part 10 move along the direction of the slide groove 7 driven by the slider 8, thereby bending the workpiece. After the bending is completed, continue to press down, and the excess edge material is cut off through the cooperation of the second elastic element 12 and the cutter 11. The support plate 19 can move in the square groove in the middle of the die 16 through the support of the second spring 22. It can be quickly demoulded by passing through the support plate 19 in the middle of the die 16 to avoid the workpiece sticking to the die 16, reducing the process of the workpiece and improving work efficiency.
