[冲制]是大量生产方法之一。为增加效率计,设计冲模时应用自动定步装置(Automatic stop)倘能获得成卷来料,则更须有自动进料装置,始能发挥[冲]的最大效能。冲模上应用的自动定步器方法很多,每因工作品的形状而异,本文只介绍一种比较可靠,制造方便,且合於一般人工进料之用者。此点在我国目前环境中最为适合。图一表示一付冲垫圈的简单冲模;当冲头 [Punching] is one of the mass production methods. In order to increase the efficiency meter, the application of automatic stop in the design of the die can achieve the maximum performance of the [red] if an automatic feeding device is needed to obtain the incoming roll. There are many ways to use the auto-pacer on the die. Due to the shape of the work piece, this article only describes a more reliable, easy to manufacture, and suitable for general artificial feeding. This point in our current environment is the most suitable. Figure 1 shows a simple punch punched washer; when the punch
