剪切,是使材料分离的加工方法。日本东京大学生产技术研究所最近研究成功了一种利用剪切实现两块薄板接合在一起的剪切压焊法。把两块薄板叠在一起,进行冲剪。当冲头与模子的间隙较小时,使材料产生局部变形,并沿剪切线产生很高的热量;另外,冲剪时,冲头与材料之间产生压力,不断地把材料从冲剪一侧向挤压的一侧产生压力。冲头反复上 Shearing, is the processing method to separate the material. The Institute of Production Technology, University of Tokyo, Japan, has recently succeeded in developing a shear-pressure bonding method using shear to join two sheets together. Stack two sheets together for punching. When the gap between the punch and the mold is small, the material is locally deformed and generates a high amount of heat along the cutting line. In addition, when the punch is cut, pressure is generated between the punch and the material, Lateral pressure side of the pressure. Punch repeatedly
