铁路机车销轴类零件磁粉检测工艺编制 学生专业：机械制造与自动化/商务英语 学生姓名：邵丽华 指导老师：史建华 摘 要 随着铁路机车的提速，对机车走行部分零件的质量要求越来越高，而零件材料在锻打、热处理和机加工过程中往往会产生各种各样的缺陷，在使用的过程中可靠性差，存在安全隐患，很可能导致安全事故。因此在重要工件的检测过程中增添了无损检测工序，加强零件的质量控制，防患于未然。 磁粉检测方便可靠，尤其检测零件的表面或近表面缺陷的灵敏度很高，是无损检测中的一种重要检测方法，被广泛采用。 本设计通过对影响磁粉检测的因素的分析，针对具体零件编制了合理的工艺规程，保证检测的有效性。 关键词：磁粉检测 工艺规程 Abstract With the speed railway locomotives, locomotive running on the quality of parts increasingly high demand for materials and parts in the forging, heat treatment and machining process tends to produce a wide range of defects in the process of using the reliability poor, the existence of security risks, it could lead to security incidents. Important parts in the process of testing the addition of non-destructive testing procedures, to strengthen the quality control of parts and take preventive measures. Convenient and reliable magnetic particle testing, in particular parts of the surface detection of near surface defects or high sensitivity, nondestructive testing is an important detection methods, are widely used. Through the design factors that affect the magnetic particle testing analysis of specific parts of the process produced a reasonable point of order to ensure the effectiveness of testing.
