摘要: 穿孔頂頭尺寸精度對(duì)穿孔毛管的壁厚精度,表面質(zhì)量,成材率以及工模具的消耗影響很大。介紹了七種穿孔頂頭的制造工藝及其特點(diǎn),以及優(yōu)選的頂頭最佳制造工藝的特點(diǎn)和效果。Abstract: The geometric accuracy of piercing-plug gives great effects on the wall-thickness accutacy. surface quality and yield of the pierced shell as well as tooling consumption. The article introduces seven plug-manufacturing processes and their features, and merits of the best therein.
