Zhang studied in this paper to die, the die is the main form as the point of failure. analyzed as follows : Die Die, Die deep, cold extrusion die in a variety of working conditions, form and detail the reasons for the failure Die Die, drawing module, the main failure mode of cold extrusion die. -- Failure of the Die wear into the early stages of normal wear stage, rapid wear stage; Failure deep sub-scale adhesion wear and abrasive wear; The main form of cold extrusion punch failure to break, wear, upsetting, Vertical fracture and fatigue cracking; Cold extrusion die Expansion and wear mainly in the form of failure. In this paper, the failure to conduct a thorough analysis of the mold, a mold study materials, mold structure, mold manufacturing, Die working conditions and the use of life to safeguard the main factors affecting the mold, and make reasonable design dies Die correct choice of materials, processing and surface hardening Toughening die, Die Mold is to improve the rational use of the safeguard measures to improve the life of stamping die.
