在机械传动中,凸轮类零件起着重要的作用。一般凸轮精度、粗糙度以及硬度、强度等技术要求较高,加工方法也较多。常用在线切割机床上加工的方法,从下料、锻压、铣平面、钻穿钢丝小孔,经热处理至切割加工内孔及外轮廓共有10多工序,按照此工艺流程,工作效率低,一个凸轮件的加工需经过穿钼丝、取钼丝往返两次,十分麻烦;凸轮加工时需留有装夹余量,造成材料浪费。
In mechanical transmission, cam parts play an important role. General cam accuracy, roughness and hardness, strength and other technical requirements, processing methods are more. Commonly used on-line cutting machine processing methods, from the blanking, forging, milling plane, drill through the wire hole, the heat treatment to the cutting hole and the outer contour of a total of more than 10 processes, in accordance with this process, the work efficiency is low, a cam Parts of the need to go through the wear molybdenum wire, take molybdenum wire from two times, very troublesome; cam processing need to leave the clamping margin, resulting in material waste.
