不锈钢垫圈冲模的选材与复合强化处理研究

Study on Material Determination of Stainless Steel Washer Cool Punching Die and Compound Intensifying Processing

为改变Cr12型电炉钢制不锈钢垫圈冷冲模使用寿命短、早期失效等现象,选用DGJW45钢结硬质合金新型模具材料和采用硼-钒(B-V)复合强化处理,模具寿命提高20￣25倍。

In order to change lower service life and falure of Cr12 stainless steel gasket cold punching die, using DGJW45 steel-bonded hard alloy and B-V compound intensifying processing, die life was enhanced 20-25 times.
