弹顶冲模,其弹顶元件——弹簧或者橡皮等,在整个冲压过程中起着非常重要的作用。除了退料和压边之外,还有预成形的作用。使冲压工序的复合加工和冲模数量减少,经济效益是很明显的。 1.盘形零件成形下料模 图1所示一盘形零件,若按习惯做法采用先下料后引伸成形复合冲模加工,往往由于毛坯材料性能的差异和引伸时金属流动的 Ejector die, the elastic element - spring or rubber, etc., plays a very important role in the entire stamping process. In addition to material removal and blanketing, there is a preforming effect. The stamping process to reduce the number of composite processing and die, the economic benefits are obvious. 1. Disc-shaped parts formed blanking Figure 1 shows a disc-shaped parts, according to the practice of using the first blanking after the extension forming composite die processing, often due to differences in the performance of the blank material and the extension of the metal flow
