一、J31-100压力机导轨拉伤情况: 1)拉伤长度:500mmm 2)拉伤宽度:32mm 3)拉伤条数:固定导轨在全长上拉通。滑块导 轨也是全长拉伤,但两端均有若 干细条。 4)最大深度:1.2mm 二、修理方法:钎焊与粘补 根据固定导轨与滑块导轨拉伤面积较大的情况,考虑到如果采用单一材料进行修补,就会出现大面积相同硬度的软材料对软材料的摩擦,很快便会产生粘接剥落。为此决定在固定导轨上采用锡铋合金修补,而在滑块导轨上采用“氧化铜粉+ 502瞬间粘合剂”修补。两种不同硬度的耐磨材料用于大面积拉伤的修补,在运动和力的作用下,避免了相互的粘接剥落。
First, J31-100 press rail strain: 1) strain length: 500mmm 2) width of strain: 32mm 3) Number of strain: the fixed rail is pulled through the whole length. The slider rail is also full-length strain, but both ends have a few strips. 4) The maximum depth: 1.2mm Second, the repair method: Brazing and sticking According to the rail and rail slide fixed rail larger area, taking into account if the use of a single material repair, there will be a large area of the same hardness of the soft Friction of the material on the soft material, it will soon produce adhesive spalling. To this end decided to fix the rail with tin bismuth alloy repair, and in the slider rail using “copper oxide powder + 502 instantaneous adhesive” repair. Two different hardness of the wear-resistant materials used for large-scale repair of tension in the exercise and force to avoid mutual bonding spalling.
