冲头和冲模是用工具钢还是用硬质合金制造,两者有不同的利弊和经济效益,此问题十分重要。在作出抉择以前,应该考虑哪些因素呢? 1.待加工零件的批量; 2.冲头和冲模的成率,以及全套模具的成本; 3.材料准备时间、模具的设计和制造总时间; 4.重磨成本和压力机停机时间; 5.最后,重要的是每一个零件的成本。 It is important that the punch and die be made of tool steel or carbide, both of which have different pros and cons and different economic benefits. What factors should be considered before making a decision? 1. The lot size of the parts to be machined; 2. The percentage of punches and dies, and the cost of a full set of dies; 3. The material preparation time, the total time of mold design and manufacturing; 4 . Refurbishment costs and press downtime; 5. Lastly, what matters is the cost per part.
