摘　　要：随着技术的发展 ,采用高强度难变形材料超薄板制成的板金零件越来越多 ,而且成形件的三维型面日趋复杂 ,对这些零件的尺寸精度及表面质量 ,尤其是厚度均匀性的要求越来越高 ,这就对成形技术提出更高的要求。而通常的软模成形技术以及常规冲压由于各自的特点构成了相应的适用范围 ,仍存在许多不足。而粘性介质压力成形 (ViscousPressureForming ,VPF)工艺由于采用粘性物质作为成形过程传力介质 。Development with the technology, more sheet metal parts with very complex three-dimensional shape are made with high strength, difficult\|to\|deform and super thin\|sheet materials. The requirement to these parts in dimensional accuracy and surface quality, especially wall\|thickness uniformity, becomes higher and higher. So the more advanced the forming technology is needed. The usually flexible die forming technology and conventional stamping method has its own application range. But because of its good characteristics, viscous pressure forming (VPF), which uses a kind of viscous material as pressure carrying medium, has good perspective.
