Blanking die

Edge mode is the use of die repair edge, so that the workpiece has a certain height, diameter and shape of the stamping die.The edge cutting die is mainly used to trim the edge of the throttle parts to make the end face clean and convenient for the next assembly.Edge model is widely used in mechanical manufacturing, auto parts production, beverage bottle processing, fastener shaping and other fields.Six-sided model standard fastener is an important base part in large quantity.Changsha nut punch bar mass production of standard compact clothing, in addition to high efficiency, high precision multi-station air conditioner, but also need high quality, long life of the mold.Starting from the working condition and failure analysis of the mould, the paper systematically studies the material selection of the mould, the hot and cold processing technology and the structure design of the mould.This study improved the inner quality of the mould.By adopting new toughening techniques such as low temperature heating and graded cooling, the microstructure of complex phase matrix with high toughness and the micromicrostructure of super carbide with fine uniform circle were obtained.At the same time, the structure design of the mould, the strength of the measuring port and the stress condition are improved.The main reason of shaoxing nut punch rod is the wear and fatigue failure of the previous broken blade, which greatly improves the life of the hexagon model.
