我們車間大批生产万能銑床、牛头刨床等鑄件,过去除了部分小件采用单称、漏模造型外,中、大件都用一般模型造型。这样,不但工时消耗多,而且鑄件尺寸精度也很难提高,模型也容易損坏,直接影响着鑄件产量和質量的提高。在这次技术革新运动中,我厂将大批生产的万能銑鑄件改为单称型板造型,并对中、大件采用一箱多模的造型方法,这样改进后显著地节省了工时,在很大程度上解决了我們 Our workshop mass production of universal milling machines, shaper and other castings, in the past in addition to some small pieces of single-name, leak-casting model, the large and medium-sized models are used in general. In this way, not only the working hours are more consumed, but also the casting dimensional accuracy is difficult to be improved, and the model is also easily damaged, which directly affects the improvement of the output and the quality of the castings. In this technological innovation campaign, I plant will be a large number of production of universal milling castings changed to single-name plate modeling, and the medium and large pieces of a box using multi-mode modeling methods, so that the significant savings after the improvement of working hours, in To a large extent, solved us
