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.

This article take the ramming mold as the object of study, mainly is takes the breakthrough point by the ramming mold expiration form, has with emphasis analyzed following several ramming mold: If the punching die, the drawing mold, the swaging die under each kind of different working condition, formed the reason which the mold expired and introduced the punching die, the drawing mold, the swaging die main expiration form in detail.Summarized the punching die expiration form to divide into the initial period attrition stage, the normal wear stage, wears suddenly the stage; The drawing mold expiration form is divided the adherency attrition and the abrasive attrition; The impact extrusion raised mold expiration form mainly for breaks off, the attrition, the upsetting, the endurance failure and the longitudinal dehiscence; The swaging denting mold expires the form mainly has the expansion crack and the attrition.This article penetrated to the mold expiration has carried on the analysis, discussed the mold material, the mold structure, the mold manufacture craft, the mold working condition and the use maintenance is affects the mold life the primary factor, thus proposed designed the mold, the correct choice mold material, uses mold tenacious processing and superficial strengthening processing, the reasonable use maintenance mold is reasonably improves the ramming mold the main measure, achieved enhanced the ramming mold the life.-------------仅供参考
