洗衣机内桶属于高盒形零件,它的成型过程比较复杂。我们对XPB2-1型洗衣机结构的特点进行了分析,选择了合理的加工方法,采用锌基合金和铸铁材料制做模具。经过试验和批量生产,取得了较满意的效果。整体拉深成型的内桶质量好,表面光洁平整,无缺陷,桶底变薄量在0.1毫米左右,成品率高(试拉深1200件,废品低于10％),成本低(降低1/3～1/2)。 Washing machine barrel belongs to a high box-shaped parts, and its forming process is more complicated. We analyzed the characteristics of XPB2-1 washing machine structure, choose a reasonable processing method, the use of zinc-based alloy and cast iron mold material. After testing and mass production, and achieved more satisfactory results. The integral deep drawing inner barrel has good quality, smooth and smooth surface, no defect, the bottom of the barrel is thinned by about 0.1mm, the finished product rate is high (1200 pieces are tested and the waste is less than 10%), the cost is low ~ 1/2).
