滚压加工一般都是利用金属在常温中的冷塑性的特点,通过运用滚压加工工具对加工部件的表面增加压力,使得工件表面产生塑性流动,最后填入到原始残留的波谷中去,减低工件表面的粗糙程度,形成致密的纤维状,最后形成残余应力层,同时有效的提高了工件的硬度和强度,对工件表面的配合性和耐磨性得到提高。本文主要分析起重机支撑液压缸缸体内孔加工工艺及加工过程中出现的影响加工质量的若干问题。 Rolling is generally the use of metal at room temperature in the cold plastic characteristics, by using the rolling tool to increase the pressure on the surface of the workpiece, making the workpiece surface plastic flow, and finally filled into the original residual trough in to reduce The surface roughness of the workpiece to form a dense fibrous, and finally the formation of residual stress layer, while effectively improving the hardness and strength of the workpiece, the workpiece surface with improved wear resistance. This article mainly analyzes some problems that affect the processing quality that occur in the process of the inner hole of the cylinder supporting the hydraulic cylinder of the crane.
