Z12-16型自动双击冷镦机原来底模的顶芯细长,垫块和模座必须随着顶芯直径的大小而变化,同时顶芯细长,在热处理中还容易变形,在生产中又易折断。另外,由于底模垫块与模座只能专用,不适应多品种生产的需要,所以我们用活动组合及通用件的办法将原底模改为图2所示的形式。 Z12-16 automatic double-headed cold heading machine The bottom core of the original mold slender, pad and mold base with the size of the top core diameter changes, while the top core slender, heat treatment is also easy to deformation, in production And easy to break. In addition, because the bottom mold pad and the mold base can only be used, does not meet the needs of multi-species production, so we use the combination of activities and common parts approach to the original model as shown in Figure 2.
