Cold heading Plus workpiece is to use the plasticity of metal, choose thermodynamics for pressure or cold drawing, to achieve the purpose of solid metal deformation. In terms of surface, cold heading goods look better than hot heading goods, smoothness is good, use level hot heading nuts are generally stronger than cold heading goods, strength to be higher, for the provision of strong customers, there is a big difference in the material.
CNC centering machine processing factory will be the top of the bar or wire at room temperature plus calcined forming. Manufacturing bolts, nuts, nails, rivets, steel balls and other parts is the key to cold heading. Forging billet materials can be copper, aluminum, carbon steel, carbon steel, stainless steel and titanium alloy ~ 90%.
Hydraulic CNC machining is mostly performed on special cold heading machines, which facilitate continuous, multi-station, automated production. The processes of cutting, heading, gathering, forming, chamfering, thread rolling, shrinking and edge cutting can be completed in sequence. The production efficiency is high, up to 300 pieces/min or more, and the diameter of large cold heading workpiece is 48mm.
The schematic diagram of cold heading bolt process is a typical process of cold headed bolt. Multi-station nut automatic cold heading machine is multi-station nut automatic cold heading machine. The bar is automatically fed into a certain length by the feeding mechanism, and the disconnecting tissue cuts it into blanks, and then the jig conveys the tissue to the agglomeration pressing and punching station for forming.
