水平试车架中的弹簧片,属于大型薄板,为关键零件。其材料是60Si2Mn,零件的精度要求较高,在加工过程中变形大,欲达到图纸要求的精度十分困难。本文经实践验证,效果较好,现介绍大型薄板零件的加工工艺,供参考。一、机械加工工艺过程图1所示为大型薄板弹簧零件,根据我厂的生产条件,制订了如下工艺: ①备料,②粗刨,③钻孔,④半精刨,⑤划线,⑥铣成形,⑦钻孔,⑧刨槽,⑨钳工,⑩热处理,(11)磨两侧平面,(12)时效,(13)平磨侧面,(14)时效,(15)平磨,
Horizontal test frame in the spring, belonging to a large sheet, a key component. The material is 60Si2Mn, high precision parts, deformation in the process of large, to achieve the accuracy of the drawings required is very difficult. This paper has been verified by practice, the effect is better, now introduces the processing of large thin-plate parts for reference. First, the machining process Figure 1 shows a large sheet spring parts, according to our factory production conditions, developed the following process: ① preparation, ② rough plane, ③ drilling, ④ fine planing, ⑤ crossed, ⑥ milling Forming, ⑦ drilling, ⑧ planing groove, ⑨ fitter, ⑩ heat treatment, (11) grinding both sides of the plane, (12) aging, (13) flat grinding side,
