Further, it is understood. The positioning column 32 is conical, and when the upper die plate 4 presses the material strip 7 in the third step 3, the product 8 originally sleeved on the positioning column 32 can be separated from the conical positioning column 32.
Further, a limiting frame 34 is further arranged on the third step 3, the limiting frame 34 is arranged on the upstream of the positioning column 32 and the positioning block 33, and the limiting frame 34 is arranged above the second bending insert 31.
It can be understood that the limiting frame 34 can effectively prevent the stamping punch from sticking and taking away the stamped product 8 due to oil stains on the stamping punch.
Further, it is understood that, referring to fig. 2, the third step 3 of the lower template 6 does not have the corresponding middle template 5.
