A method for peeling the surface of a traction motor rotor guide bar

Abstract

The invention discloses a method for scalping the surface of a rotor guide bar of a traction motor, and specifically relates to the technical field of rail transit rotor guide bars. According to the principle of metal cutting, surface defects such as inclusions, peeling and foaming on material surfaces are removed by drawing with a die parallel to a blade of a rotor guide bar. The method comprisesthe specific steps of die drawing and matching, die making, material stabilizing, and drawing and scalping, wherein the die making step is completed by the three steps of (1) die core processing, (2)die sleeve processing and (3) die assembly. Compared with the existing surface treatment, the method has the advantages that (1) equipment production replaces manual grinding, the productivity is liberated, the production efficiency is improved, and the operating environment of workers is improved; (2) more effective and rapid removal of surface defects is realized, the surface quality of the guide bar is improved, and high surface consistency is achieved; and (3) manual repair of finished products is reduced, the waste rate caused by surface quality problems is lowered, the production cost is lowered, and the market competitiveness of products is improved.

Description

technical field [0001] The invention relates to the technical field of rail transit rotor guide bars, in particular to a method for peeling the surface of a traction motor rotor guide bar. Background technique [0002] With the development of rail transit and high-speed rail, the requirements for its traction power-asynchronous traction motor are getting higher and higher. The motor rotor is the core component of the asynchronous traction motor. ) to provide power. Generally, the rotor of a high-speed asynchronous traction motor is embedded on the iron core with guide bars, and welded together with the end ring. Therefore, the performance and quality of the guide bar are directly related to the performance of the asynchronous traction motor. [0003] At present, the surface treatment method of the rotor guide bar is mainly to remove surface defects by manual grinding. There are the following problems: ① manual production, low production efficiency, long production cycle, ...

AI Technical Summary

Problems solved by technology

There are the following problems: ① manual production, low production efficiency, long production cycle, affecting product delivery; ② low product quality, often need to be polished and reworked; ③ final product surface quality consistency is poor, rework maintenance intensity is high, and the qualified rate of finished products is low

[0004] Production by manual grinding not only has a long production cycle, low production efficiency, poor product surface consistency, and high later repair rate, it has become a bottleneck affecting production.
