【摘要】：随着工业的快速发展,中厚板钢材消费量逐年提高。从2003年开始,我国掀起了宽厚板轧线建设高潮;随着轧线设备的大型化及自动化程度的提高,精整线设备的剪切能力也随之进行了升级;由于外商的技术保密,国内对轧线设备的主体设备结构研究较少,国内在这些设备的使用维护方面的经验也很欠缺;但随着技术的引进和多年的使用,国内很多企业加强了轧钢设备技术的消化和吸收,很多厂家具备了自主研发的能力,具备了设备关键部位备品、备件的加工制造及改造能力;与此同时,随着设备的使用和对主体设备构造和工作原理的了解,国内各个设备使用厂家也在设备维护方面积累了很多宝贵的经验;这对于我国钢铁业具有积极的意义。本文以秦皇岛首秦金属材料有限公司4300mm滚切式双边剪和定尺剪为研究对象,对多轴多偏心滚动式剪运动原理进行了分析。文中介绍了滚切式双边剪的设备规格参数、传送、移动、夹送、剪切等主要功能;介绍了定尺剪的设备规格参数、夹送、剪切等主要功能。分析了它们各主要机构的基本参数和工作原理;最后,对双边剪和定尺剪在设备使用和维护过程中的出现的比较典型的设备问题进行了分析,重点讨论了双边剪主滑板的磨损问题,定尺剪剪刃机构调整及滑块键的问题,以及由此引起剪切质量问题;通过材料晶相组织和受力分析,找到问题原因,提出了相应改进措施;后期设备的运行情况表明,经改进后,减少了设备维护的费用,减少了设备故障率,产品的质量也得到了改善。
[Abstract]:With the rapid development of industry, the consumption of plate steel is increasing year by year. Since 2003, there has been a high tide of wide and thick plate rolling line construction in our country. With the improvement of large-scale rolling equipment and automation degree, the shear ability of finishing line equipment has also been upgraded. The domestic research on the main equipment structure of rolling line equipment is less, and the domestic experience in the use and maintenance of these equipment is also very short; however, with the introduction of technology and the use of the equipment for many years, Many domestic enterprises have strengthened the digestion and absorption of steel rolling equipment technology, and many manufacturers have the ability of independent research and development, and have the ability to process and manufacture spare parts and spare parts in key parts of the equipment; at the same time, With the use of the equipment and the understanding of the construction and working principle of the main equipment, the domestic equipment manufacturers have accumulated a lot of valuable experience in the maintenance of the equipment, which has a positive significance for the steel industry of our country. In this paper, the motion principle of multi-axis and multi-eccentric rolling shear is analyzed with 4300mm rolling shear and fixed scale shear of Qinhuangdao Shouqin Metal material Co., Ltd. This paper introduces the equipment specification parameters, transmission, movement, clip, shear and other main functions of the rolling bilateral shear, and introduces the main functions of the gauge shear, such as the equipment specification parameter, the clip, the shear and so on. The basic parameters and working principles of their main mechanisms are analyzed. Finally, the typical equipment problems in the process of equipment use and maintenance are analyzed. In this paper, the wear problem of the main slide plate, the adjustment of the shear blade mechanism and the slider key are discussed, and the shearing quality problems are also discussed, and the reason of the problem is found through the analysis of the structure and force of the material crystal phase. The operation of the equipment in the later period shows that the cost of maintenance is reduced, the failure rate of the equipment is reduced, and the quality of the product is improved.
