[0035] refer to Figures 1 to 5 A side punching die of a shell according to an embodiment of the utility model is described.

[0036] like Figures 1 to 5As shown, the side punching die of the shell includes a lower die base 100; an upper die base 200, which can be lifted and lowered on the lower die base 100; a punching assembly 300, which includes a punch push plate 310 and a plurality of convex modules 320. The punch push plate 310 is arranged at one end of the upper die base 200 close to the lower die base 100, and the plurality of convex modules 320 are movably connected to the lower die base 100. The plurality of convex modules 320 are in a circular array, and the workpiece 10 is integrally sleeved on the outside of all the convex modules 320. The plurality of convex modules 320 are enclosed to form a groove, and each convex module 320 can move radially along the groove. The groove is coaxially arranged with the punch push plate 310 and is located directly below the punch push plate 310. The punch push plate 310 penetrates into the groove and horizontally pushes the convex module 320 along the radial direction of the groove to drive the convex module 320 to punch the workpiece 10 radially outward along the groove.

[0037] like Figure 1 and Figure 3 As shown, the upper die base 200 is located at the upper end of the lower die base 100, and the upper die base 200 can be lifted and lowered above the lower die base 100.

As a result, the upper die base 200 moves downward to drive the punch push plate 310 to penetrate the groove. The punch push plate 310 penetrates into the groove and abuts against all the convex modules 320. The upper die base 200 continues to drive the punch push plate 310 to move downward. At the same time, the punch push plate 310 horizontally pushes all the convex modules 320, so that all the convex modules 320 move horizontally outward along the corresponding radial direction of the groove, thereby penetrating the workpiece 10 from the inside to the outside one by one, and leaving the burrs on the outside of the workpiece 10 while completing the stamping of the oil hole, so as to reduce the difficulty of burr removal and improve the production quality and production efficiency of the product.

[0038] In some specific embodiments of the present invention, the punching assembly 300 also includes a concave module 330, which is fixedly arranged on the lower die base 100.
