Abstract
Description
Technical Field
[0001] This utility model belongs to the field of piercing equipment technology, and in particular relates to a piercing equipment for the production of metal parts. Background Technology
[0002] Punching in metal parts production is a process that uses pressure to cause plastic deformation of metal materials to create holes. Punching equipment is classified by power source into hydraulic, pneumatic, and electric drive types, and by automation level into manual, semi-automatic, and fully automatic punching machines. The core of the punching machine consists of a frame, power system, mold, positioning mechanism, and control system, and is used for batch processing of holes in various metal parts.
[0003] In existing methods of pressing holes in tubular metal fittings, the outer wall is often clamped for processing. However, due to the hollow structure of the tubular fittings and the tendency of the wall to become unbalanced under stress, the area around the hole often experiences radial shrinkage due to the lack of inner wall support under the external pressing force. This can lead to deformation problems such as dents and pipe wall twisting, affecting the dimensional accuracy of the hole. Therefore, an improvement is needed. To address this, a pressing device for the production of metal fittings is proposed. Utility Model Content
