摘要
截齿作为采煤机重要刃具,具有易损、数量多、成本大等特性。为了获得使用寿命长的采煤机截齿,对截齿材料、成形工艺方法进行分析,研究了一种热处理及钎焊一体的新型截齿成形工艺,对实现该工艺的自动化生产设备进行分析,对提高截齿使用寿命的表面处理技术进行研究。为采煤机截齿使用寿命的提高、生产成本的降低、采掘效率的提升等方面提供参考及技术支持。
As an important cutting tool for shearers,the picks have the characteristics of being vulnerable,large in quantity and large in cost.In order to obtain shearer pick with long service life,the pick materials and forming process methods have been analyzed.A new type of pick forming process that integrates heat treatment and brazing has been studied.The automatic production equipment that realizes the process has been analyzed and the surface treatment technology to improve the service life of the pick has been researched.The research provides references and technical support for increasing service life of shearer pick,reducing production costs and improving mining efficiency.
