AI Technical Summary

Technical Problem

The existing quick-change structure for fastener cold heading forming dies cannot achieve rapid replacement, resulting in poor die stability, low efficiency, and easy displacement after replacement, which affects the forming accuracy.

Method used

The mold quick-change structure adopts components including a base, support plate, telescopic column, sliding column, and clamping mechanism. The design of telescopic column and rotating shaft enables quick disassembly and precise positioning of mold. Springs and buffer plates reduce vibration and ensure that the mold can still be stably positioned after multiple changes.

Benefits of technology

It enables rapid mold replacement and stable positioning, improves production efficiency, reduces downtime, and ensures molding accuracy and mold lifespan.

Abstract

The utility model relates to the technical field of die quick replacement structures, and discloses a fastener cold heading forming die quick replacement structure which comprises a base, a supporting plate is fixedly connected to the top of the base, second telescopic columns are fixedly connected to the front side and the rear side of the supporting plate, and a plurality of long blocks are fixedly connected to the tops of the second telescopic columns. A plurality of moving columns are slidably connected to the front sides and the rear sides of the long blocks, sleeve plates are slidably connected to the middles of the outer walls of the moving columns, a plurality of screws are connected to the front sides and the rear sides of the moving columns in a threaded mode, and a plurality of sliding columns are fixedly connected to the top of the periphery of the supporting plate. According to the utility model, the lower die, the die block and the push plate slide downwards along the sliding column by retracting the telescopic column II, after the die is formed, the spring and the springing column are extruded to push away residues falling on the push plate, and when the die is replaced, the screw is far away from the moving column and is pulled out of the moving column, so that the die structure can be rapidly replaced, and the product stability is ensured.
