我厂YB32-300型四柱万能液压机,由于润滑不良和超负荷使用,立柱圆柱面的1/3被研伤,研伤深0.5～2.1mm,长800～1200mm。为了缩短修复时间,我们在现场不卸拆的情况下采用胶粘法修复,其工艺如下。 1.准备工作用φ168×9.5×650mm钢管两根。将其内径加工至α150_(+0.1)~(+0.2)mm,然后从轴向切开作覆衬模待用。将原衬套(瓦)未被研伤的1/2做研磨瓦。 2.表面处理先用汽油或无水乙醇清洗立柱表面,后用钢丝刷反复洗刷研伤沟槽(顺着沟槽刷),用小锯条或刮刀清除积瘤和氧化皮,使其表面露出金属光泽。接着用丙
I plant YB32-300 four-cylinder universal hydraulic press, due to poor lubrication and overload, column cylindrical surface 1/3 was injured, research injury depth 0.5 ~ 2.1mm, length 800 ~ 1200mm. In order to shorten the repair time, we use adhesive method to repair the case without demolition on site, the process is as follows. 1. Preparatory work with two φ168 × 9.5 × 650mm steel. The diameter of its processing to α150 _ (+0.1) ~ (+0.2) mm, and then cut from the axial lining for stand-by mode. The original bushing (tile) was not grind 1/2 grinding tiles. 2. Surface treatment First clean the column surface with gasoline or ethanol, and then use a wire brush to repeatedly wash the grinding groove (along the groove brush). Use a small saw blade or a scraper to remove the tumor and scale to expose the surface of the column luster. Then use C
