Blanking die

Standard compact parts are important basic parts in large quantity.Mass production of standard compact parts in addition to high efficiency, high precision multi-station cold pay machine, but also need high quality, long life of the mold.In the case that production demand cannot be met, the high quality hexagonal edge cutting model developed successfully has a service life of 213t#j compared with the current domestic mold, which is equivalent to the same kind of imported mold, and the price is only 18?L / 1.Based on the working conditions and failure analysis of the die, the material selection, hot and cold processing technology and structural design of the die were systematically studied.This study improved the inner quality of the mould.It takes W6Mo5Cr4VZ steel as the edging model.The microstructure of multiphase matrix with high toughness and the microstructure of fine, homogeneous and round excess carbide were obtained by adopting several new techniques such as low temperature heating and graded cooling.At the same time, the structure design of the die is improved, and the strength and stress of the measuring port are improved.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.
