酚醛层压布板调整垫片落料冲孔复合模设计

Design of Blanking-Piercing Compound Die for the Phenolic Laminated Cloth Plate Adjustment Gasket

由于现有冲压技术资料对调整垫片所用材料酚醛层压布板冲压性能没有详细介绍,本文通过对酚醛层压布板进行了冲裁工艺试验,分析了两种结构类型不同的模具冲裁零件断面质量的不同,提出了采用外形和内孔都压边落料冲孔复合模,并详细介绍了模具结构特点,并采取有效措施,保证了调整垫片断面质量要求。

Because of existing stamping technology data to adjust gasket materials for phenohc laminated cloth plate stamping performance in detail, this article through to the phenolic laminated cloth plate blanking process test, analyses the two different types of structure of die blanking part the different cross section quality, puts forward the shape and inner hole are all pressure edge blanking piercing compound die, and introduced the die structure characteristics, and take effective measures to ensure the quality of the adjusting shim sections.
