A study of crease problems for terminal plate

针对端子冲件在冲模调试过程中出现的弯曲折痕问题,采用理论分析,在进行力学计算和分析后,并利用有限元软件LS-DYNA对其弯曲变形过程进行进一步数值模拟分析,并最终给出最优解决方案。利用该解决方案设计和制造的端子冲模在生产上已获成功,不但解决了端子冲件在冲压过程中出现的折痕问题,还大大缩短了冲压模具的设计制造周期,降低了成本。生产实践表明给出的解决方案是有效和可行的。

For the crease problems of terminal plate in stamping process,the solution is proposed based on the theoretical analysis and the numerical analysis of the deformation process using the finite element program（LS-DYNA）.According to the solution,not only solved the crease problems for terminal plate in stamping process,but also greatly shorten the design and manufacture cycle of stamping die,the stamping die is manufactured and has been successful in production,which shows that the proposed solution is effective and feasible.
