摘要
分析了汽车前保险杠托架的工艺特点,制定了合理工艺方案,采用板料三维成形分析软件PAM-STAMP对其拉深成形工序进行了数值模拟仿真,通过对FLD图和成形结果的分析得到了合理的拉深凹模型面。设计了经济合理的模具结构,制造了汽车前保险杠托架的全套模具,并在校形模中加了限位块,有效控制了成品件与立柱装配的尺寸精度,最终生产出合格产品。该工艺方案极大地提高了材料的利用率和劳动生产率,节约了生产成本和有效提高了模具设计质量及效率。
The processing characteristics of the front bumper bracket are analyzed, and a reasonable process scheme is worked out. The three-dimensional sheet metal forming analysis software PAM-STAMP are adopted to simulate the bracket＇ s drawing process. Then the surface of die is proved fine through analyzing the FLD diagrams and the forming results. An economical and optimized die structure is decided, and a complete set of dies of the bracket is designed. The spacing block is added in the sizing mold,which control the size precision of end products and assembling columns actively, and finally the certified products. The material utility and the labor productivity are raised, the production cost is saved, and the mold design quality and the efficiency are improved effectively.
