Preferably, a rotating ring is rotatably sleeved between the through groove and the sliding rod, and a first insertion rod that can extend to the inside of the rotating ring is movably inserted on the outer end surface of the through groove. The inner end surface of the ring is integrally formed with a limiting slide block that can be slidably connected to the inside of the limiting through groove.

A three-hole stamping die proposed by the utility model that replaces the drilling process has the beneficial effects of:

Through the adjustment assembly, the contact height between the abutment plate and the part to be processed can be changed by adjusting the position of the first slider on the adjustment assembly, and the elastic member can be changed by adjusting the position of the second slider on the adjustment assembly. Compared with the existing single structure, the telescopic length can be better adjusted according to the needs and the flexibility of use can be improved.
