Description
技术领域
本发明属于煤矿综采工作面液压支架立柱领域，具体涉及一种导向套熔覆防腐工艺。
背景技术
煤矿综采工作面液压支架的重要部件是立柱，立柱主要由外缸、中缸、活柱、大小导向套和密封组成，其中大、小导向套目前采用的防腐工艺为镀铜、镀锌，但这种防腐工艺镀层和基体是物理结合，再加上镀层无法避免的空隙率从而极易造成锈蚀、点蚀使导向套过早报废。
发明内容
本发明为了解决传统防腐工艺容易造成锈蚀、点蚀，使导向套过早报废的问题，进而提供了一种导向套熔覆防腐工艺。
本发明采用如下技术方案：
一种导向套熔覆防腐工艺，采用熔覆铜合金工艺代替现行电镀工艺对导向套进行熔覆防腐，熔覆层的参数为：
熔覆层厚度：0.5mm；
熔覆层硬度：HB167—200；
熔覆层与基体为冶金结合；
熔覆层表面粗糙度：≤1.6。
导向套的熔覆部位包括导向套内侧的防尘密封槽、导向带槽和密封圈槽。
本发明通过采用熔覆铜合金工艺可以使报废的导向套重新被利用，解决了传统镀锌、镀铜方式存在的锈蚀、点蚀等问题，能有效使用寿命可再延长3—5倍。
附图说明
图1为立柱的组成；
图2为导向套的结构示意图；
图中：1-外缸、2-中缸、3-活柱、4-大导向套、5-小导向套、6-A面、7-防尘密封槽、8-导向带槽、9-螺纹、10-密封圈槽。
具体实施方式
导向套结构如图2所示，通常包括防尘密封槽、导向带槽、密封槽、螺纹部分以及外侧凸台（图示中的A面）等，用锰合金钢制作。为了使报废的导向套重新被利用，本发明采用熔覆铜合金工艺对报废导向套进行修复，具体的熔覆层参数为：
熔覆层厚度：0.5mm
熔覆层硬度：HB167—200
熔覆层与基体为冶金结合
熔覆层表面粗糙度：≤1.6。
