摘要
针对保险座原进口模具无法满足产品要求,通过分析、计算,对冲压加工工艺进行了改进,有效的解决了冲孔尺寸变化和拉裂、掉底问题.在保证产品质量的同时,解决了科研、生产的急需.
The stamping process is improved because the original imported die for the safe cover can not meet the product requirements, which resolves the issues including stamping hole size changing,leakage and bottom dropping. The design will guarantee the product quality and meet the research and production needs.
