冲压加工用于小批量生产的障碍,除了模具的调整和安装很费时间外,还在于金属模具一般较贵,模具费用在冲压成本中所占的比例很高。 为了减少模具的制造费用,研制了各种简易冲模和通用模,有了相当程度的推广。但是在简易冲裁模方面,过去对它的优点虽已作了某种程度的强调,目前却使用得还不很广泛。 Stamping For the small-scale production of the obstacles, in addition to mold adjustment and installation is time-consuming, but also in the metal mold is generally more expensive, the cost of stamping die in a high proportion of cost. In order to reduce the cost of mold manufacturing, developed a variety of simple die and universal mold, with a considerable degree of promotion. However, in terms of simple blanking, although its advantages have been somewhat emphasized in the past, it has not been widely used at present.
