硬质合金冷镦组合凹模的设计

Design of Combination Matrix for the Hard Alloy Cold Forging Die

针对标准件生产中冷镦凹模寿命低的问题,采用了硬质合金组合凹模,文章叙述了硬质合金材料的选择原则,介绍了硬质合金组合凹模模套的设计方法,确定了镶套过盈量的确定方法,从而保证了硬质合金组合凹模具有较高的使用寿命。

In view of the standard production of cold forging matrix life is low, the author used the hard alloy combination matrix, the article describes principle of selecting hard alloy materials, this paper introduces the design method of die set of hard alloy combination matrix, determines the set of determination method of the over surplus quantity, thus ensuring the service life of the hard alloy combination matrix have higher.
