我厂采用双头铰链卷制模具(图1)加工锁扣(图2c)。这套模具的特点是利用下模的往复运动来自动送料,单个的工件在级进模每个工步上相互保持间隔,象在单个工序模具上压制一样。
I plant double-headed hinge rolling mold (Figure 1) processing lock (Figure 2c). The mold is characterized by the use of reciprocating motion to automatically feed the lower mold, a single workpiece in the progressive die each step to maintain the spacing of each other, as in a single mold on the same process.
