锻造用模具一般都设计成整体的。但是整体结构的模具制造周期长,模具材料消耗多,热处理工艺复杂,不仅制造费用贵,而且模具保管困难,对品种多、批量小的模锻件是非常不合适的。为适应多品种小批量生产的需要,一般可采用镶块结构的锻模。镶块模具有模具制造周期短,能节约模具材料和换模快等优点。我厂的生产实践证明,镶块模座容易在斜楔紧固凹口的根部产生疲劳裂纹。这就直接影
Forging molds are generally designed as a whole. However, the overall structure of the mold manufacturing cycle is long, mold material consumption, heat treatment process is complex, not only expensive to manufacture, but also difficult to maintain the mold, for more varieties, small quantities of forging is very inappropriate. In order to meet the needs of many varieties of small batch production, the general inlay structure can be used forging die. Insert mold has a mold manufacturing cycle is short, mold material can be saved and mold change faster. The production practice of our factory proves that the insert block seat is easy to produce the fatigue crack in the root of the wedge fastening recess. This is a direct shadow
