武建工业安装加工厂在车轮轮箍工程中,曾接受了七千多平方米钢模板的制作任务。每平方米各种规格钢材有约150个孔眼,钻孔的工作量很大。初期,我们所用的方法是:型钢按需要长度下料后,在一个专用的画线盘上分十五根为一组画线,并打洋冲。这一方法虽比以前的用薄铁皮作样板,在型钢上画线,打洋 Wu Jian Industrial’s installation and processing plant has accepted more than 7,000 square meters of steel formwork in the wheel hub engineering. There are about 150 holes per square meter of steel of various specifications, and the drilling work is very heavy. In the early days, the method we used was: After the steel was cut to the required length, it was divided into a set of 15 drawing lines on a dedicated drawing line and hit the ocean. Although this method is more than the previous model with a thin iron sheet, draw lines on the steel, hit the ocean
