摘要
对管座、管壳的拉伸工艺进行了详细地分析,原工艺为两副连续拉伸模和一道攻螺纹工序,现改为1副连续拉伸套冲带自动攻螺纹的多工位级进模来冲压,实现了多工位级进模的自动化生产,介绍了该制件的排样设计及模具结构设计的特点,并解决了拉伸件与攻螺纹工序"整合"在一起的难题。实践证明,改进后的模具结构精简、可靠,生产出的制件质量合格、稳定性好。减少了机床的投资及工人的劳动强度,大大提高了生产效率,降低了生产成本。
Through the drawing process of pipe header and shell are analyzed in detail, for two pairs of the original process continuous drawing die and a tapping screw, incumbent deputy continuous drawing into 1 set of blunt with automatic tapping screw thread of multi-station progressive die stamping, automate the multi-station progressive die production, introduces the parts of the characteristics of the layout design and die structure design, and solved the drawing and tapping screw thread process the problem of ＂integration＂ together. Practice has proved that the improved die structure compact, reliable, produce the qualified product quality and stability is good, also reduced the investment of machine tool and the labor intensity of workers, greatly improving the production efficiency, reduce the production cost.
