我厂设有支农车间,多年来,支农车间接收到各县、公社农机具使用部门要求维修的零件特点是:种类多,同类件数少,任务紧,时间短,没有生产准备时间,难于制备专用设备和工艺装备。针对上述情况,我们设计制造了加工箱体和法兰盘、端盖等类零件的简易通用钻模。长期使用后证明,这些钻模有如下优点: 1.一模多用,应用范围广。孔径不同的箱体和直径不同的法兰盘上的等分孔均可在其上加工; 2.加工质量好。一般精度孔要求的圆周直径公差
I plant with support for agriculture, over the years, support farm received counties, communes, agricultural machinery used by the maintenance department requirements of the parts are: more types, the same number of pieces less, the task is tight, time is short, no production preparation time, difficult Preparation of special equipment and process equipment. In response to the above situation, we have designed and manufactured a simple general-purpose drilling die for machining cases, flanges and end caps. After long-term use proved that these models have the following advantages: 1. A multi-purpose, wide range of applications. Different diameter of the box and the diameter of the flange on the equally divided hole can be processed on it; 2. Processing quality. General requirements for precision hole diameter of the circle diameter tolerance
