我厂50年代从前苏联进口的K366A-400闭式双点大台面(1400×2500mm)压力机,已使用30多年。由于零件尺寸较大,有的模具无法装到压力机的工作台面中心,因此模具受力一般都偏离滑块中心,造成滑块工作受力时往往倾斜偏移,原铸铁镶条一旦间隙调整得不均匀,镶条就断裂,每年单台机床更换断裂镶条数达8～10根,维修费用在万元以上。 1989年我们对铸铁镶条进行维修改进,其方法如下: 1.把原铸铁镶条本体改为ZG35铸钢,即镶条的形状尺寸不变,其本体强度增加了3倍多。避免和减少
I plant 50 years ago from the former Soviet Union imported K366A-400 closed two-point large table (1400 × 2500mm) press, has been used for more than 30 years. Due to the larger size of the part, some molds can not be fitted to the center of the workbench of the press, so the mold force generally deviates from the center of the slider, causing the slider to tend to tilt when subjected to force. Once the gap of the original cast iron is adjusted Inhomogeneous, inlaid on the fracture, the annual replacement of a single machine to insert the number of broken up to 8 to 10, the maintenance costs in more than 10,000 yuan. In 1989, we made improvements to the cast iron strip. The method is as follows: 1. The original cast iron strip body was changed to ZG35 cast steel, that is, the shape of the strip was unchanged, and its body strength increased more than 3 times. Avoid and reduce
