拉延模具板料定位设计

Sheet Positioning Design of Drawing Die

根据实际生产中板料的多样性,为了降低生产成本,合理利用汽车板料,准确地定位板料,需要多种挡料杆来满足对不同姿态板料的需求。结合车间现场模具调试,通过对现有结构设计的分析,基于自动化传输冲压线,总结了拉延模具压料面在不同状态下的板料定位设计问题。设计初期确定板料状态,根据不同状态下的生产过程,确定挡料杆以及板料定位方式。

According to the diversity of sheet metal in actual production,a variety of keep-off rods are needed to meet the needs of sheet metal with different postures,in order to reduce production cost,make rational use of automobile sheet metal and accurately position sheet metal.Based on the analysis of the existing structure design and the automatic transmission stamping line,the sheet positioning design of the pressing surface of the drawing die in different states is summarized.At the early design stage,the sheet metal state is determined.According to the production process under different states,the keep-off rod and sheet metal positioning mode are determined.
