摘要:

 针对托架连接条零件生产效率低及产品合格率低的问题,对其结构进行了分析,设计了1套级进模具。针对产品上有向上和向下2个不同的<折弯+卷圆>结构特征,设计了2组不同的<折弯+卷圆>工序模具。为了克服回弹现象,使折弯角度为90°,设置了预折弯和折弯2道工序。为了保证卷圆的形状,设置了预卷圆①、预卷圆②和卷圆3道工序。为了保证工序件折弯后能够顺利脱模,将凸模设计为滑块结构,可以通过滑块侧向移动实现脱模。最终,使用该级进模具生产的产品质量稳定,并实现批量生产。

 For the problems of low production efficiency and product qualification rate for bracket connecting strip parts, its structure was analyzed, and a set of progressive die was designed. Then, two sets of <bending+coiling> process dies were designed,aiming at two different <bending+coiling> structural features, such as upward and downward. In order to overcome the spingback phenomenon and the bending angle of 90°, two processes of pre-bending and bending were set up. In order to ensure the shape of coil, three processes, namely, pre-coiling ①, pre-coiling ② and coiling, were set up. In order to ensure that the process parts were smoothly demolded after bending, the die was designed as a slider structure, and the demolding was achieved by the lateral movement of slider. Ultimately, the products produced using this progressive die have stable quality and realize the mass production
