前言在金属线生产中,拉丝模(简称线模)的消耗在生产成本中占有很大的比例,因此,提高线模的利用率,历来是拉丝生产中的一项重要和迫切任务。为了减少配模计算工作和节约线模的储备数量,国内外都曾在等延伸拉丝机上采用 Introduction In the production of metal wire, the consumption of wire drawing dies (referred to as wire die) occupies a large proportion of the production costs, therefore, to improve the utilization of wire dies has always been an important and urgent task in wire drawing production. In order to reduce the number of mold work and save the amount of reserve mold line, both at home and abroad have been used in the drawing machine extension
