Experimental Research on Metal Deformation during Cone Roll Piercing

摘要: 为研究菌式穿孔机穿孔时轧件金属的变形规律,进行了穿孔轧卡试验及变形区各断面轧件壁厚测量,计算分析了壁厚变化规律。在穿孔过程中,金属存在明显的管壁增厚现象。提出了在工具设计、调整参数方面应遵循的原则。

Abstract: To get the law of metal deformation of the work piece being rolled with the cone roll piercing mill,rolling jamming experiment and measurements of wall thickness of different work-piece sizes were conducted,based on which law of the wall thickness variation is calculated and analyzed.It is observed that during piercing,wall thickness of the work-piece being rolled is getting increased obviously.Principles con cerning tool design and parameter setting of the mill are also emphasized.
