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 ,具有独特的优点因而具有广阔的应用前景
With the development of technology, more and more sheet metal parts made of ultra-thin sheet of high-strength and difficult-to-deformable material are increasingly complicated. The three-dimensional profile of forming parts is increasingly complicated. The dimensional accuracy and surface quality of these parts, especially the thickness uniformity Higher and higher requirements, which put forward higher requirements for forming technology. However, conventional soft-mold forming techniques and conventional stamping, due to their respective characteristics, constitute a corresponding scope of application, there are still many deficiencies. The Viscous Pressure Forming (VPF) process has broad application prospects due to its unique advantages due to the use of viscous materials as the force transmission medium in the forming process
