根据支撑板的技术要求,对支撑板进行了工艺分析,介绍了支撑板弯曲模具的主要工作原理,然后针对支撑板弯曲模在弯曲时易出现的弯曲回弹、弯裂等质量问题,研究了解决办法,确定了改进措施;特别分析了弯曲高度较小的厚板料在弯曲时因受凸模的挤压力作用,会在工件表面产生压痕的问题,从而阐述了所采取的工艺方法;针对性地描述了如何对模具的弯曲凸模、弯曲凹模等主要工作部件进行结构改进,从而解决了支撑板弯曲的先后顺序问题,保证了支撑板的表面质量。
According to the technical requirements of the support plate, the process of the support plate is analyzed, the main working principle of the support plate bending die is introduced, and then the quality problems such as bending rebound and bending which are easy to appear when the bending plate of the support plate flexes are studied. Solution, and determine the improvement measures; In particular, the analysis of the bending height of the smaller plate material in the bending due to the impact of the punch pressure, the workpiece surface will have indentation problems, and thus elaborated on the process adopted ; How to improve the structure of the main working parts such as the bending punch and the bending die of the mold in order to solve the order of the bending of the support plate and ensure the surface quality of the support plate.
