Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Examples

Referring to fig. 1-3, a stamping die with a replaceable stamping die head comprises a base 1, a top plate 2 is arranged on the upper side of the base 1, a loop bar 3 and a pressure-bearing bar 4 are fixedly connected between the base 1 and the top plate 2, the loop bar 3 and the pressure-bearing bar 4 are respectively arranged on the left side and the right side, a hydraulic cylinder 5 is fixedly connected to the lower end of the top plate 2, the hydraulic cylinder 5 is PY497-100/70 in type, a bottom table 6 is rotatably connected to the outside of the loop bar 3, the bottom table 6 is in a slat type, at least two groups of stamping mechanisms are arranged on the bottom table 6, each stamping mechanism is composed of a stamping table 7 and a tool bit 8 fixedly connected to the lower end of the stamping table 7, the tool bits 8 are different in type, two sides of the stamping table 7 are both connected with the bottom table 6 through a reset piece, and the reset piece can.

More specifically, the reset piece comprises slide bar 10 and reset spring 11, and the lower extreme fixed connection of slide bar 10 is in the upper end of base frame 6, and the upper end of slide bar 10 runs through to slide and sets up on moulding-die platform 7, is equipped with the slip hole 15 that matches with the slide bar on moulding-die platform 7, and reset spring 11 cover is established outside slide bar 10, and slide bar 10 can adopt cylindricly still can adopt square pole, and reset spring 11's both ends respectively with base frame 6 and moulding-die platform 7 fixed connection.
