Abstract

The utility model discloses a puncher pin rapidly replacing device which comprises a punch die handle (1), a fastening nut (2) and a puncher pin (3). Outer threads are arranged at the end, connected with the puncher pin (3), of the punch die handle (1). Outer threads are arranged at the end, connected with the punch die handle (1), of the puncher pin (3). The fastening nut (2) is arranged at the connecting position of the puncher pin (3) and the punch die handle (1). The punch die handle (1) is connected with the upper end of the fastening nut (2) in a threaded mode. The puncher pin (3) is connected with the lower end of the fastening nut (2) in a threaded mode. The lower end of the fastening nut (2) is arranged to be an inner conical step with the small outside and the large inside, and an outer cone matched with the inner conical step of the fastening nut (2) is arranged at the top of the puncher pin (3). A rapid replacing assembly is composed of the three parts, punch dies in different sizes can be rapidly replaced in use, and the puncher pin rapidly replacing device is simple in structure, saves the die adjusting time to the maximum degree, is safe and reliable, greatly reduces the machining cost and improves the machining efficiency.
