我厂轧四分厂系开坯分厂,是炼钢和成材分厂之间必不可少的中间工序。因一次意外事故,使升降台(一台主要工艺设备)曲轴断裂了。该分厂是我厂唯一的开坯厂,每停产一天,将少创利润10万元以上。经商量,我们采用了如下修复措施,只花了两天功夫,就圆满地解决了这个难题,达到了预期效果。一、确定方案曲轴形状尺寸如图1所示,成品净重约为250kg。因意外事故,在图1所示的地方断裂。该机系水压机锻件,限于我厂锻造能力,厂内无此毛坯。观察曲轴,我们发现除曲轴腹板断裂外,其余表面均尚良好。为了增加曲轴薄弱部分的承载能力,我
I plant rolling fourth sub-plant Bilubian plant, steelmaking and ready-made plant essential intermediate process. The crankshaft of the lift (a major process equipment) broke due to an accident. The factory is the only factory in our plant to open a billet, stop production for one day, will create less profits more than 100,000 yuan. After consultation, we used the following repair measures, it took only two days Kung Fu, it satisfactorily solved this problem, to achieve the desired results. First, determine the program Camshaft shape and size shown in Figure 1, finished net weight of about 250kg. Due to an accident, break at the place shown in FIG. 1. The machine hydraulic forgings, limited to our forging capacity, the factory without this rough. Observing the crankshaft, we found that except for the crankshaft web fracture, the remaining surfaces were still good. In order to increase the carrying capacity of the crankshaft weak part, I
