本科毕业设计题目：φ100mm热轧无缝钢管定径机设计PAGE \* MERGEFORMATII摘 要在城市建设和机械产品生产制造过程中热轧无缝钢管发挥了关键作用，因此在广泛的市场需求驱动下，热轧无缝钢管生产加工技术得到快速发展。热轧无缝钢管生产工艺是指管坯在结晶温度以上时进行轧制定径的生产过程，在这个过程中，由于其耗能低，产品性能特点较好，已被广泛应用。热轧无缝钢管生产技术经过这么多年的发展已经逐渐成熟，应用也比较广，目前在国内外大多数无缝钢管生产厂家都采用热轧工艺。 随着时代的发展和技术的进步，一些新设备逐渐发展并运用到热轧无缝钢管生产过程中来，提高无缝钢管轧制质量，推动其工艺的不断发展。热轧轧制无缝钢管生产流程主要包括圆管坯、环形加热、二辊斜轧穿孔、连轧或挤压、脱管、定(减)径、冷却、矫直。热轧无缝钢管生产过程中以穿孔、轧管、定径（减径）为主要变形工序。三个工序所用的设备分别为穿孔机、轧管机、定（减）径机。本设计主要是对定（减）径机作设计、计算。主要内容：传动轴的设计计算、直齿锥齿轮的设计计算、轧辊的设计计算、其他零件的选取。关键词：三辊定径机；轧制；设计计算全套图纸加153893706AbstractHot-rolled seamless steel pipe in the city construction and machinery products in the production and manufacturing process have played a pivotal role, so in the broad market demand driven, hot-rolled seamless steel pipe production and processing technology has been rapid development. Hot-rolled seamless steel pipe production process is the metal above the crystallization temperature of the rolling sizing production process, because of its low energy consumption, product performance characteristics of a variety of good and has been widely used.Hot-rolled seamless steel pipe production technology after years of development has gradually matured, has also been widely promoted and applied, at home and abroad a number of seamless steel pipe manufacturers, most of the use of hot-rolled process. With the development of the times and the progress of technology, some new equipment gradually developed and applied to the hot-rolled seamless steel pipe production process to improve the quality of seamless steel pipe rolling, and promote the continuous development of its technology.Hot rolling rolling pipe production process mainly includes round tube, heating, perforation, three rolling, rolling or extrusion, detaching, sizing (reducing), cooling, straightening, water pressure test. Generally in the production process to perforation, rolling, sizing (reducing diameter) as the main deformation process. The design is mainly for the set (minus) diameter machine for the design,
