冷滚压是一种无屑精加工工艺。它比切削方法精加工效率高,且起光整及强化加工表面作用,增加了表面的耐磨性。我厂生产的 YG 110油缸缸简,材料为40铬无缝薄壁短缸筒(长314毫米)。原采用珩磨工艺,效率低、光洁度差、为提高强度,还需热处理。去年在学习兄弟单位经验的基础上,我们组织了以老工人为主体的三结合技术革新小组,设计制造了如图1所示的滚压头。这种滚压头的最大特点是既保证了加工精度和光洁度(达9)又可以采用大进给量,因而效率高。
Cold rolling is a no-crumb finishing process. It is more efficient than the cutting method of finishing, and the role of finishing and strengthening the surface, an increase of wear resistance of the surface. The YG 110 oil cylinder produced by our factory is simple in material and is made of 40 chrome seamless thin-wall short cylinder (length 314 mm). The original honing process, low efficiency, poor finish, in order to improve the strength, but also heat treatment. Last year, on the basis of learning the experience of our brother units, we organized a three-pronged technical innovation team with old workers as the main body and designed and manufactured the rolling head as shown in Figure 1. The most important feature of this rolling head is that it guarantees both machining accuracy and finish (up to 9) and large feed rates for high efficiency.
