图1所示是一种铝制品旅行梳。采用一般冲孔模结构型式冲制齿形凹模容易损坏,且零件质量差。我们设计了一付冲齿模(图2),冲次近10万,刃口完好,冲制零件质量好。 一、模具结构 模具结构与一般冲孔模相似,现仅将主要不同之点简述如下。 Figure 1 shows a travel aluminum comb. Punching die with a general structure of the punch-shaped concave die easily damaged, and poor quality parts. We designed a pair of punching die (Figure 2), the red nearly 100,000, cutting edge intact, punched parts of good quality. First, the mold structure Die structure similar to the general punch, now only the main differences are as follows.
