Ultrasonic metal surface treatment method for steel rail welded joint
An ultrasonic metal surface treatment method for a steel rail welded joint comprises the following steps: (1) determining a to-be-machined surface, wherein the to-be-machined surface is a semi-n-shaped curved surface where a locomotive wheel makes contact with a steel rail, and the cross section of the to-be-machined surface is a semi-n-shaped curve; (2) selecting a machining starting position ofthe to-be-machined surface of the steel rail, and setting an ultrasonic tool bit of an ultrasonic metal surface treatment device at the starting position; and (3) simultaneously machining the ultrasonic tool bit in the longitudinal direction and the transverse direction of the to-be-machined surface, wherein the ultrasonic tool bit walks in a straight line in the longitudinal direction, and the ultrasonic tool bit walks in the semi-n-shaped curve of steel rail profiling in the transverse direction. According to the ultrasonic metal surface treatment method for the steel rail welded joint, ultrasonic surface treatment is conducted on the non-rotating-surface semi-n-shaped curved surfaces of the heat affected zones on the two sides of the locomotive steel rail welded joint in use, the machining method is simple and accurate, and the machining efficiency is high.
钢轨焊接接头超声波金属表面处理方法，包括如下步骤：(1)确定待加工面，所述待加工面是机车车轮与钢轨接触的半n形曲面，所述待加工面的横断面是半n形曲线；(2)选择钢轨待加工面的加工起始位置，将超声波金属表面处理装置的超声波刀头设定在所述起始位置；(3)所述超声波刀头在所述待加工面的纵向上和横向上同时进行加工，所述超声波刀头在纵向上走直线，所述超声波刀头在横向上走所述钢轨仿形的半n形曲线。本发明提供的钢轨焊接接头超声波金属表面处理方法，针对正在使用中的机车钢轨焊接接头两侧热影响区的非回转面半n形曲面进行超声波表面处理，加工方法简单，准确，加工效率高。
