Metal products backbone enterprises in our country, most is five, 60 s were completed and put into operation, the equipment, technological level, production capacity, product quality, etc., lags far behind developed countries; Although in the late seventy s and early eighty s, some enterprises introduced various types of high-speed wire drawing machine, stranding, cabling machine, all kinds of production lines, etc., but the industry of silk machine equipment level is still relatively backward. According to concerning sectional statistic, wire drawing machine equipment level in our country at present: belongs to the level of equipment in the eighty s about the I. 15%, 60 s and seventy s equipment accounted for about 30%, the level of 40 to 50 s level of equipment accounted for about 55-60%. Many manufacturers dominated by ordinary pulley wire drawing machine wire drawing machine, this is largely limits the quality of products, improve the yield and variety increase; After entering the eighty s, various products manufacturers in order to improve product quality, yield, increase product variety, from the developed countries the introduction of various types of wire drawing machine
