研究了不同压边力加载模式对盒形件拉深成形的影响。以汽车承载底板为研究对象,将其三维模型导入Dynaform软件进行冲压成形模拟,设置了前处理相应的一些工艺参数并得到初步模拟结果。通过设定典型分析数据,分析了整体压边圈及分区压边圈在不同加载模式下的相关结果。研究结果表明:传统的整体压边圈恒定压边力加载模式,结构简单易于实现生产;采取了分区压边圈后,其板料在拉深过程中厚度变化更均匀;整体压边圈变压边力如果采用合适的值对提升零件拉深质量有较显著的改善作用。
The influence of different blank holder force loading modes on the deep drawing forming of box parts was studied. Taking the car bearing floor as the research object, the three-dimensional model was imported into Dynaform software to carry out the stamping forming simulation, the corresponding preprocessing parameters were set and the preliminary simulation results were obtained. By setting the typical analysis data, the overall results of the blank holder and the partition blanker under different loading modes were analyzed. The results show that the traditional blank holder constant blank holder force loading mode has the advantages of simple structure and easy production; after the blank holder is partitioned, the thickness of the blank sheet is more uniform during the drawing process; If the use of appropriate value of the edge force to improve the quality of parts has a more significant improvement.
