内桶件是洗衣中较重要的一个大型零件。以往,由于洗衣机厂没有双动拉伸压力机,只能在通用压力机上采用分段拉伸、然后对焊成一体的工艺方案来制造。产品结构如图1所示。这种制造方法不仅浪费原材料、工序多、工时多、成本高,而且影响了产品的美观。我们经过多次试验,把内桶件改在双动拉伸压力机上进行整体拉伸,获得了成功。这种制造工艺方法,不仅大大简化了工艺过程,节约了原材料,提高了生产率,降低了成本,而且产品美观,深受群众欢迎,现已投入生产。下面就概略介绍一下内桶件的整体拉伸工艺。
Inside the barrel is a laundry more important a large parts. In the past, because the washing machine factory does not have double-acting stretch press, it can only be manufactured by using the sectional stretch on the universal press and then welding the integrated process. Product structure shown in Figure 1. This manufacturing method not only waste raw materials, processes and more, working hours, high cost, but also affect the appearance of the product. After many tests, we changed the inner barrel to a double-tensioned stretch press to achieve overall success. This manufacturing process, not only greatly simplifies the process, saving raw materials, improve productivity and reduce costs, but also beautiful products, welcomed by the masses, is now put into production. Here’s a brief overview of the overall stretch of the barrel pieces.
