DETAILED DESCRIPTION
[0026] Clearly, the described embodiments are merely a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.
[0027] Referring to Figures 1 to 5 The D-shaped drainage hole forming die has a lower die base 1, an upper die base 2 capable of moving up and down relative to the lower die base 1, an upper mounting plate 5 mounted on the upper die base 2, an upper punch 8 with a first end fixedly mounted on the upper mounting plate 5, an upper step 81 provided on a second end of the upper punch 8, an upper pressure plate 6 slidingly sleeved on the upper punch 8, the upper pressure plate 6 being connected to the upper mounting plate 5 through a damping mechanism, a lower die 10 mounted on the lower die base 1, the lower die 10 being provided with a lower die hole 11 matched with the upper punch 8, and the lower die hole 11 being provided with a lower step 111 matched with the upper step 81. In operation, the upper die base 2 moves downward, the upper pressure plate 6 contacts the workpiece and then compresses the workpiece together with the lower die 10, then the upper die base 2 continues to move downward, the upper punch 8 extends out to cooperate with the lower die 10 to form a D-shaped hole of the workpiece, and the upper punch 8 and the lower die hole 11 are both provided with steps to form the steps of the D-shaped hole.
