多年来,我厂生产的汽车翻斗车及装载机中都有多件液压高压软管接头。软管接头是一个多台阶而各角度不同的零件(见图1)。在车床上用一般内圆车刀加工,无法保证工件的尺寸和角度,生产效率低,成本高。利用高速钢车刀(白钢车刀)改制成多台阶成型车刀,见图2。使用效果良好,工效比普通加工方法提高十几倍以上,有着明显的经济效益。一、刀具制作多台阶成型车刀关键在制作这一关。用白钢车刀改制,首先,要校正。再按工件各台阶(有5个台阶和4个台阶)尺寸划线。然后在工具磨床上刃磨各尺寸和角度。磨削过程中,注意刃口不得烧伤和退火,各刃面粗糙度为Ra0.63。R角可用小型半边圆油石修磨。
Over the years, I plant the dump truck and loader have a number of hydraulic high-pressure hose connector. Hose connector is a multi-step and different angles of the parts (see Figure 1). In the lathe machining with a general inner turning tool, can not guarantee the size and angle of the workpiece, low productivity, high cost. The use of high-speed steel turning tool (white steel turning tool) into a multi-step molding turning tool, shown in Figure 2. The use of good results, the efficiency of more than ten times more than ordinary processing methods, has obvious economic benefits. First, the tool making multi-step forming turning the key in the production of this off. With white steel turning system, first of all, to be corrected. Then press the workpiece each step (with 5 steps and 4 steps) dimension crossed. Sharpen each size and angle on a tool grinder. Grinding process, pay attention to the edge can not be burned and annealed, the razor surface roughness Ra0.63. R angle can be small semi-round round stone grinding.
