The factors affecting the service life of mould

The influence of the stamping process and die design and measures to improve die life. ( 1) With the influence of raw material with cold stamping. For example: raw material thickness tolerance is not in conformity with the requirements, material performance fluctuation, surface quality is poor and not clean A. Stamping before dealing with the grades of raw materials, thickness, surface quality, strict inspection B. Ensure the quality of material surface and clean ( 2) Layout and layout method and the influence of a boundary value impact on the die life is very large, unnecessary reciprocating feed layout method and too little on value is often caused by mould wear and intensive sharply on injury of important reasons. ( 3) The influence of the mold structure and the guidance precision is necessary and reliable guidance, to reduce the wear work parts, avoid intensive face injury is very effective. ( 4) Die geometric parameters influence the shape of the intensive, clearance and fillet radius on stamping forming not only affects greatly, and has a very big influence on mold wear. Die mould for the material properties and the influence of the influence of heat treatment of die life quality is one of the most important factors in the various factors affecting the service life of mould. Mold processing after the influence of mould processing mold surface roughness had a great influence on the life of the mould, so according to the parts, the choice of reasonable processing technology. The use of mould, preventive maintenance and the correct use, maintenance, and the influence of mould is a important aspect to improve die life. It includes the mold correct installation and adjustment; Pay attention to keep the mold cleaning and reasonable lubrication; By feeding, double; Strictly control punch into the depth of the concave die, control of calibration curve, processes such as plastic upperpunch bottom dead center position; In time of grinding, polishing, etc.
