Blanking die

Edge mode is the use of die edge repair, so that the workpiece has a certain height, diameter and shape of the stamping die.The edge-cutting type is mainly to trim the edge of the drawing parts to make the end face clean and convenient for the next step assembly.Edge model is widely used in mechanical manufacturing, auto parts production, beverage bottle processing, tightening die matching and other fields.Hexagon trim model standard fastener is an important basic part with large quantity and wide area.Mass production of standard compact parts in addition to high efficiency, high precision multi-fenghua edge cutting die station cold payment machine, 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.The microstructure of complex phase matrix with high toughness and the microstructure of fine homogeneous round excess carbides were obtained by adopting a variety of new toughening techniques such as low temperature heating and graded cooling.At the same time, the fujian edge cutting die into the structure of the mold design, improve the strength and stress of the orifice.The wear and fatigue failure of the hexagonal edge cutting mode is mainly caused by the fracture of the traditional splitting edge, which greatly improves the life of the hexagonal edge cutting mode.
