195柴油机主轴承冲压翻边工艺,是目前轴瓦行业普遍采用的工艺,它较之摩擦焊边、冲压镶边、压铸铝边等工艺,具有效率高,成本低,废品率低等优点.用AlSn20Cu—钢材料,采用冲压成型的方法,整体制作195主轴承,碰到的最大难题是止推边达不到要求厚度,边沿合金层变薄.这是由于冲压翻边的特殊工艺造成的,翻边时在翻边力的作用下,止推边产生弯曲变形,上表面存在拉应力,下表面存在压应力,同时在周向拉力的作用下,还
195 Diesel main bearing stamping flanging process is the commonly used technology in the bearing industry at present, which has the advantages of high efficiency, low cost and low rejection rate compared with friction welding edge, stamping and edge-pressing, aluminum scrap casting, etc. With AlSn20Cu - Steel materials, the use of stamping method, the overall production 195 main bearing, the biggest problem encountered is the thrust side can not reach the required thickness, the edge of the alloy layer thinning.This is due to the special process of stamping flange caused, turn Under the action of the flange force, the edge of the thrust bending deformation occurs, there is tensile stress on the upper surface, the lower surface of the existence of compressive stress, while the role of circumferential tension, but also
