内容简介：

摘要模具与压力是决定冲压质量、精度和生产效率的两大关键因素。先进的压力机只有配备先进的模具，才能充分发挥作用，取得良好效益。模具的发展方向为：充分运用IT技术发展模具设计、制造。网络技术的广泛应用提供了可靠的信息载体，实现了异地设计和异地制造。同时，虚拟制造等IT 技术的应用，也将推动模具工业的发展；缩短金属成形模具的试模时间。当前，发展液压高速试验压力和拉伸机械压力机，特别是机械压力机上的模具试验时间可减少80%，具有巨大的节省潜力；车身制造中的级进冲模发展迅速。近年来，级进组合冲裁模在车身制造中开始得到越来越广泛的应用。但是，级进组合冲模技术的应用受拉伸深度、导向和传输的带材边缘材料表面硬化的限制，主要用于拉伸深度比较前的简单内零件。 关键词：压力、质量、精度、生产效率AbstractDie pressure and decided to ram the quality, accuracy and efficiency of the two key factors.Only advanced presses equipped with advanced mold, can fully play its role and achieved good results.Die direction of development: full use of IT technology development die design, manufacture. The extensive application of network technology provides a reliable information carrier, achieved a tele-design and manufacture different places.At the same time, virtual manufacturing, and other IT technology applications, will also promote the development of industries die; shorten the trial metal forming die-time.At present, the development of high-speed hydraulic test pressure and tensile mechanical press, in particular on the mechanical press die test of time can be reduced by 80%, with huge savings potential in the body manufacture the rapid development of progressive die.In recent years, the composition of the Progressive Die in manufacturing in the body began to be more widely used.However, the composition of the Progressive Die technology applications by drawing depth, direction and transmission edge of the strip surface hardening of the restrictions, mainly used for drawing a simple
