摘　　要：根据穿孔机工具中的轧辊的设计特点,系统地探讨了锥形辊穿孔机的轧辊参数设计原则,分析主要参数的计算公式和设计中应注意的问题。分析认为:科学合理地设计锥形辊穿孔机轧辊,可以使减径量最小,却不影响咬入,对穿孔工序极为有利;此外,还能减少轧制缺陷,尤其在生产难轧钢种时,其优势更明显。设计合理的锥形辊穿孔机可以提高产品质量、降低轧制能耗和工具消耗。According to the design characteristics of the roll used as one of the piercing tools,the design principle for the CTP roll parameters is systematically discussed here in the paper,and the calculation formula for the major para-meters and the issues as need to be focused on during the design process are analyzed.The analysis leads to such a con-clusion as follows.Scientific and reasonable design of the CTP roll will minimize the reduction amount without any negative effect on the bite,which is very helpful for the piercing step;moreover rolling-caused defects will also be reduced;particularly when producing steels which are normally rather hard to be managed,the said roll shows obvious advantages.Generally speaking,the properly-designed cone type piercer(CTP)will bring about such advantages as better product quality,lower energy consumption for rolling and lower tools consumption as well.
