摘　　要：冲压件生产过程中影响因素复杂,而网格试验的正确使用,可以有效地从定性、定量2方面指导冲压件缩颈、拉裂问题的优化,使冲压件在冲压成形过程中拥有更大的“安全裕度”,从而加快问题的解决速度。通过成形极限曲线(FLC)分析、Comsmart设备测量,从而生产指导性数据,可以量化和反应模具实际状态,进而做出针对性的模具裕度调整,以及对调整后的模具裕度进行验证。The factors affecting stamping parts in the production process are complex,and the correct use of grid test can effectively guide the optimization of necking and tearing of stamping parts qualitatively and quantitatively,can make stamping parts have a greater“Safety margin”in the stamping process,thus speeding up the speed of problem solving.Through Forming Limit Curve(FLC)analysis and Comsmart equipment measurement,the production guidance data can quantify and reflect the actual status of the mould,and then make specific mould margin adjustment and verify the adjusted mould margin.
