管件在焊接时,焊口需加工出圆弧形状,采用铣床加工,难以满足大批量生产要求。通过对骑式摩托车上悬管零件成形工艺分析,采用具有工艺简单、成本低、效率高、质量好等优点的冲压切口成形。设计了两套切口模具,并提供冲切凸模和凹模图形与尺寸,对冲切过程中管壁变形情况进行了简要分析。通过多年实践检验,该工艺及模具应用情况良好,产量稳定。 Pipe welding, welding mouth to be machined arc shape, the use of milling machine processing, it is difficult to meet the requirements of mass production. Through the analysis of the forming process of the suspended parts on the riding motorcycle, the stamping with the advantages of simple process, low cost, high efficiency and good quality is adopted. Two sets of incision molds were designed, and the shape and size of punch and die were provided. The deformation of tube wall during punching was analyzed briefly. After many years of practical testing, the process and die application is good, the output is stable.
