轮式起重机轮辐圆周分布的8个孔通常需要多次冲压成形,采用自动分度装置则可以一次装夹冲出。介绍了一种轮式起重机轮辐自动分度冲孔模。论述了模具结构特点和工作原理。在转盘转动和复位时,其分度装置采用了两组斜销限位机构带动和限制了工件的转动。模具避免了多次冲压时定位困难、精度低的问题,零件质量好,生产效率高。
The eight holes distributed circumferentially on the wheel crane spokes usually require several times of stamping, and the automatic indexing device can be used to clamp out once. A kind of wheel crane automatic index punching die is introduced. Discussed the mold structure and working principle. In the turntable rotation and reset, the indexing device uses two sets of oblique pin limit mechanism to drive and limit the rotation of the workpiece. Mold to avoid multiple punching positioning difficulties, low accuracy problems, parts of good quality, high production efficiency.
