AI Technical Summary
Technical Problem
The high production cost of gearbox connectors in the prior art is mainly due to the significant material waste during the processing and forming of cylindrical bars.
Method used
The cold heading production line for gearbox connectors includes forming components, shrinking rod components, drilling components, opening components, stretching components, and extrusion components. Through the cold heading process, the fixing part, positioning part, connecting part, and stepped groove are gradually formed, reducing material waste.
Benefits of technology
Near-net-shape forming of gearbox connectors was achieved, reducing production costs and improving processing quality and stability.

Abstract
The application relates to the field of cold upsetting equipment, in particular to a gearbox connecting piece cold upsetting forming production line which comprises a seat body, a shaping assembly, a rod shortening assembly, a punching assembly, a hole opening assembly, a stretching assembly and an extruding assembly; the shaping assembly, the rod shortening assembly, the punching assembly, the hole opening assembly, the stretching assembly and the extruding assembly are sequentially and spacedly connected to the surface of the seat body; and a circular bar is sequentially subjected to the shaping assembly, the rod shortening assembly, the punching assembly, the hole opening assembly, the stretching assembly and the extruding assembly. In the application, the shaping assembly, the rod shortening assembly, the punching assembly, the hole opening assembly, the stretching assembly and the extruding assembly are arranged, cylindrical bar material is sequentially subjected to cold upsetting extrusion to form a gearbox connecting piece, near-net forming is realized, the material loss is reduced, and therefore the production cost of the gearbox connecting piece is reduced.
