Abstract

本实用新型涉及煤矿采掘机组上使用的抗磨损激光强化截齿，它是在截齿本体锥面上加工有激光强化层。本实用新型利用激光能量束对截齿的锥面进行激光熔覆、表面合金化或激光淬火进行强化，从而提高截齿端部锥形位置的硬度和耐磨性能，延缓磨损速度，有效保护硬质合金刀头，延长截齿的使用寿命。

Description

抗磨损激光强化截齿
技术领域
本实用新型涉及煤矿采掘机组上使用的截齿。
背景技术
截齿是采掘机组上直接切割煤岩的关键零件，它是一个锥面体，在锥尖部镶嵌有硬质合金头。其失效方式主要是磨损失效，磨损失效的主要形式为截齿端部基体磨损，最终导致合金头剥落。使用寿命较短。因此，提高截齿端部的耐磨性，是延长使用寿命的关键。
实用新型内容
本实用新型的目的解决截齿的耐磨性问题，提供一种抗磨损激光强化截齿。
一种抗磨损激光强化截齿，它包括截齿本体和硬质合金头，其特征是，截齿本体锥面上加工有一层激光强化层。
本实用新型经在煤矿井下半煤岩巷道试验，与普通截齿相比，激光熔覆后的截齿寿命延长了3-4倍，表面合金化后的截齿寿命延长了5-6倍，表面淬火后的截齿寿命延长了3-4倍。
因此，激光技术在截齿表面工程技术上的应用，是利用激光束能量高度集中、方向高度集中的特性，在大气环境下进行无污染操作，在廉价金属材料表面形成一层硬度高、无裂纹，且与基体呈冶金结合的高性能涂层，将金属良好的坚韧性和涂层材料的高硬度、高化学稳定性、高耐磨性结合起来，创新了高性能耐磨层的生产工艺。
附图说明
图1是抗磨损激光强化截齿的主视图。
