摘要
拉刀是一种高生产率的多齿刀具,利用其后一个刀齿高出前一个刀齿来切削金属,从而得到所需工件形状。拉刀工作时,同时参加工作的刀刃长度较长,一次通过工件表面即能完成工作,时间短,生产效率高。本文针对某型气动凿岩机中转动套花键的加工工艺,介绍了拉刀设计的全过程。
the broach,a multi-toothed tool of high productivity,has its teeth arranged in a way that the front tooth is located higher than the one after it,through which a desired part shape is abstained.The spline broach has a long cutting edge so that the cutting can be finished within one go on the part surface.As a result,this process features less time and higher productivity.The paper covers the complete design procedure of a broach based on the process of the rotary sleeve＇s splines of a type of pneumatic rock drill.
