锥形罩是我厂新产品的重要零件之一,见图1。该零件工艺较复杂,难度较大。我们经过了长时期的反复试验,终于试制成功。并已成批投入生产,现将锥形罩加工工艺加以总结,以供兄弟单位参考。一、工艺分析 1.工件的外形基本为一锥台型的薄壁旋转件,见图2。根据h/d及半锥角α的数值,工件属于低锥形工件。这类工件加工通常采取在压力机上拉伸。但是在拉伸时,由于模具凸模的压力通过工件 Cone cover is my factory new products, one of the important parts, shown in Figure 1. The parts process is more complex and difficult. After a long period of trial and error, we finally succeeded in trial production. And has been put into mass production, cone processing technology is now summarized, for the fraternal unit for reference. First, the process analysis 1. The basic shape of the workpiece is a cone-shaped thin-walled rotating parts, shown in Figure 2. According to the value of h / d and half cone angle α, the workpiece belongs to low taper workpiece. This kind of work piece is usually taken on the press machine stretching. However, due to the die punch punch pressure through the workpiece
