辽宁科技大学本科生毕业设计 第  PAGE 32 页 中厚板矫正机压下机构设计 摘要 轧钢生产已经成为冶金生产行业中把钢坯轧制成钢材的重要生产环节，具有产量大、品种齐全，生产过程机械化自动化程度高等许多优点，是满足国民生产需要的重要技术。并且随着科学的发展，轧钢生产行业与传统机械业进一步紧密的结合在一起。利用轧钢生产技术，提高轧制产品的质量，减少轧制生产时间，提高成材率，降低生产成本和材料的利用率已经成为轧钢机械设计的主要目标。而矫直技术是提高板带钢产品表面质量和平坦度的重要环节。本文介绍了中厚板产生不平直度的原因，中厚板矫直机的种类，中厚板矫直机基本参数、力能参数的确定，中厚板矫直技术的发展。依据板带矫直机的生产过程和工作原理，经过现场实习，首先从中板矫直机的总体方案评述开始???依次进行了压下电机的选择计算,压下螺丝、压下螺母的的设计及校核，蜗轮蜗杆的设计及校核，轴承的设计及寿命校核，并且研究了矫直机的发展方向。 关键词：压下系统;矫正力 ;矫正机; Type Plate Straightening Machine Pressure System Design Abstract The product of steeling has become an important tache of rolling billet to be steels in the metallurgy produce industry. The strongpoint of this industry is have great output of the production is the variety production. and the produce process is very mechanization and automatization.The steeling is a important technology to fulfill the country need.Also with the development of steeling industry the industry integrate very well with the traditional mechanism industry. How to make use of the steeling manufacture technology, enhance the rolling quality of the production, decrease the product of rolling time,enhance the rate of product useful rolled steel .The straighting technology is a important tache to enhance the surface quality and flatness of the production .This article describes the reasons inflatedness occurred on medium and heavy plate．The type of levelers，the determination of basic parameters，energetic date for 2600 plate leveler,the decision for complete structure and design，the development of plate leveling technology .This article design basis on the board-strip straighting machine produce process and the working principle in the steel metallurgy. This article first begin with the scheme review of the energetic date for 2600. Then go along with choice of the pressure electromotor, the design and checking of pressing the nut and the pressure screw, Worm and worm gear equipment.than design and checking the life
