瓦形垫圈是机床电器和低压电器元件上的接线零件,广泛地使用在交流接触器、继电器和各种控制电器上。我厂参考了国外各种不同的瓦形垫圈结构,结合本厂产品的具体使用要求,对瓦形垫圈进行了改进设计,改进后的结构见图一。我们设计了瓦形垫圈一次成形级进模,其排样如图二所示。这付模具的特点是:利用凸模的斜刃形式,同时 Watt-shaped washers are wiring components for machine and low-voltage electrical components and are widely used in AC contactors, relays and various control electronics. I refer to a variety of foreign plants watt-shaped washer structure, with the specific use of our products, the design of the washer-shaped washers, the improved structure shown in Figure 1. We designed a washer-shaped washer progressive die, the layout shown in Figure 2. This pay mold is characterized by: the use of punch oblique form, at the same time
