我段段修车辆中,木体敞车维修量较大,需更换的门板、墙板、端板也比较多。如按工艺分解就必须把紧固螺栓松掉,然后把旧板取下,而大部分螺栓已锈死,没有锈死的螺栓也因螺栓头部的四方体与压铁方孔配合不好,随之转动,造成分解困难。以往我们分解车辆上部门板、墙板、端板时,采用气焊切割的方法,把旧螺栓一切两段。这样不仅氧气用量大,效率低,而且旧螺栓全部要报废。气焊切割时,螺栓周围的木板出现烧着和烤焦的现象,直接影响了修车质 I paragraph paragraph repair vehicles, wooden body gondola maintenance, need to replace the door, wall panels, end plates are also more. If the decomposition according to the process must loose the fastening bolts, and then remove the old board, and most of the bolts have been rusty, rust-free bolts also because of the head of the bolt body square and the pressure with the square hole with the poor, with The rotation, resulting in decomposition difficulties. In the past we break down the vehicle door panels, wall panels, end plates, the use of gas welding cutting method, the old bolt all two. This not only the amount of oxygen, low efficiency, and all the old bolts to be scrapped. Gas welding cutting, the wood around the bolt burned and burned phenomenon, a direct impact on the quality of car repair
