在冷挤压生产过程中,为了提高工件表面质量和模具使用寿命,减少挤压过程中的摩擦力,采用了将模具或毛坯工件进行磷化处理(磷酸盐处理)的方法。经过一年多时期的生产实践证明效果良好,使轴碗模具的使用寿命由原来每套平均挤压1200件提高到4500件,工件的表面质量也大大提高。(一)磷化处理的特性磷化处理是使金属表面形成一层不溶性金属的磷酸盐薄层,约0.06～0.1毫米。根据处理温度及成分的不同,磷酸盐
In the cold extrusion production process, in order to improve the surface quality of the workpiece and the life of the mold to reduce the friction during the extrusion process, the mold or blank workpiece phosphating (phosphate treatment) method. After more than a year of production practice has proved effective, so that the life of the shaft bowl mold from the original 1200 per set of extrusion to improve to 4500, the workpiece surface quality is also greatly improved. (A) the characteristics of phosphating Phosphating treatment is to make the metal surface layer of insoluble phosphate metal layer, about 0.06 ~ 0.1 mm. According to the treatment temperature and composition of the different phosphate
