用于机器制造,以板材冲压方式生产的弯曲件的形状是多种多样的(农业机器中所有的弯曲件占零件总数的50％)。这就大大地加重了生产工艺准备工作的复杂性和繁重性。为了提高弯曲件的质量和合理地利用材料、设备和模具,必须在有科学依据的、最佳的(例如成本最低的)、统一的、适用于大批量生产的、弯曲件冲压工艺设计的基础上,开发出自动设计系统,现有技术参考资料中那些在零件加工典型解决和分类方法基础上作出的有关冲压工艺设计的建议,基本上只适用于小批量生产。对于大批量生产来说,这些建议就显得不全
For machine construction, the shape of the bent parts produced by sheet stamping is varied (all bending parts in agricultural machines account for 50% of the total number of parts). This greatly aggravated the complexity and complexity of the production process preparation. In order to improve the quality of bending parts and the rational use of materials, equipment and molds, it is necessary to base them on scientifically based, best (for example, lowest cost), uniform, flexural stamping process design suitable for mass production , An automatic design system has been developed. The proposals in the prior art references for stamping process design, which are based on typical solution and classification methods for part machining, are basically applicable only to small batch production. For high volume production, these suggestions seem incomplete
