摘要
介绍链条弯链板产品的结构特点及工艺要求,通过新旧工艺分析,决定采用连续送料、斜(滑)楔结构、冲孔+挤孔的自动连续冲挤新工艺,以达到弯链板4孔加工的尺寸精度及粗糙度值的要求。
Introduced the structure characteristics and technological requirements of bend sidebar of chain, and through analyzing new ＆ old technology, to use a new technology of automatically continuous punching ＆ extruding of continuous feed, wedged structure, punching-hole and extruding-hole, reaching the requirements of dimensional accuracy and finish of the four-hole processing of bend sidebar.
