Working Principle Analysis And Equipment Problems Of Heavy Plate Rolling Shear

In recent years, with the fast development of industry, the production and consumption of heavy plate increased year by year. From 2003, China set off a heavy plate rolling line construction climax. Along with the large scale and the improvement of the automation of rolling equipment, the shear capacity of finishing line equipment was upgraded. Because of foreign technology security, the research on the structure of the rolling line equipment is few, The maintenance experience of these devices is also few; But with the introduction of technology and use for many years, Many enterprises have carried out the digestion and absorption of equipment technology;many manufacturers have the ability of independent research and development, with the manufacturing of key parts and spare parts of the equipment; At the same time, with the use and understanding of the equipment structure and working principle, Domestic steel plants have accumulated a lot of experience in the maintenance of equipment; Has a positive meaning to the iron and steel industry of our countryThis paper takes Qinhuangdao Shouqin metal material Co. Ltd. 4300 mm double side trimming shear and dividing shear as the research object, the multi axis multi eccentric rolling shear movement principle was analyzed. This paper introduces in detail the rolling equipment specifications, bilateral shear transfer, move, pinch, shear and other major functions; introduces the specifications of the equipment parameters, dividing shear pinch and shearing functions. The basic parameters and working principle of the main equipment was analyzed. Finally, The typical problems of the equipment during operation and maintenance were analyzed. The discussion is focused on the main slide wear problem of DSS and the slide button problem of the DS, and puts forward the corresponding improvement measures; The operation of equipment in the later period shows that after improvement, the cost of equipment maintenance is reduced, equipment failure rate is reduced, and the quality of the product is improved.
