多工步连续模是一种高效率、高质量、长寿命的先进模具,应用于大量生产小型冲压件,可以获得显著的经济效益,因而国内外都重视其设计和制造技术的研究。本文介绍国外一种新型设计系统——VSD(Versatile System of Design)的部分资料,可供研制多工步连续模的参考。一、VSD的实质多工步连续模VSD可应用于各种异形平片或成形冲压件。图1是一个例子。无论凸模、凹模用于冲裁或成形工序,也无论其工作部分形状是圆形还是非圆形,凸模、凹模的外形固定部分都加工成圆形。采用这种新型结构,凸模固定板、脱料板和凹模固定板均只需加工圆形安装孔,保证孔距与孔径精度,使加工难度大为降低。这样,高精度多工步连续模的制造难度就集中在
Multi-step continuous die is a kind of advanced mold with high efficiency, high quality and long life. It can be used in mass production of small-sized stamping parts, and can obtain significant economic benefits. Therefore, both domestic and foreign enterprises pay attention to the research of their design and manufacturing technology. This article introduces a new foreign design system - VSD (Versatile System of Design) part of the information for the development of multi-step continuous mode reference. First, the real multi-step VSD Continuous mode VSD can be applied to a variety of shaped flat sheet or forming stamping parts. Figure 1 is an example. Regardless of the punch, die for punching or forming process, and regardless of the shape of the working part is circular or non-circular shape, punch, die fixed part of the shape are processed into a circle. With the new structure, the punch fixing plate, the stripper plate and the die fixing plate only need to process the round mounting hole to ensure the hole pitch and the hole diameter precision, so that the processing difficulty is greatly reduced. In this way, the difficulty of manufacturing high-precision multi-step continuous mode is concentrated
