货车轮对轮缘焊修是恢复车轮外部形状,延长车轮使用寿命,提高利用率的一项重要工艺措施。 我厂已开展了轮缘焊修工艺多年,节约了大量车轮,缓解了车轮原材料短缺的矛盾,取得了明显的经济效益和社会效益。 我厂轮缘焊修采用的是一台EP—2×300型双头自动堆焊机,其工作特点是轮对直立不动,焊机绕轮转动,立式焊接,但辅助时间长,操作不便,效率低。为此,我们改进焊机结构,并设计制作一套工艺装备(见图)。
Wagon wheel flange repair is to restore the external shape of the wheel, to extend wheel life and improve utilization of an important process measures. I plant has carried out the rim welding repair process for many years, saving a lot of wheels, to alleviate the contradiction between the wheel of raw materials shortage, and achieved significant economic and social benefits. Our factory flange welding is using an EP-2 × 300 double automatic welding machine, its work is characterized by wheel upright, the welder around the wheel rotation, vertical welding, but aided a long time, the operation Inconvenient, inefficient. To this end, we improve the welding machine structure, and design and manufacture of a set of technology and equipment (see photo).
