目前电子工业引进生产线对冷轧带材的剪切提出一系列的要求:剪切带材的侧弯≤1mm/m,边部基本上无毛刺,宽度公差在±0.1 mm。目前国内纵剪机一般存在的问题:直度不能符合要求,根据冶金部标,冷轧带材的侧弯≤3mm/m;剪切后带材边部有毛刺;剪切宽度公差大;分条后卷得不紧、不齐、尤其不能适应大卷重的要求;软态料无法剪
At present, the introduction of production lines in the electronics industry puts forward a series of requirements for the shearing of the cold rolled strip: the side strip of the sheared strip is ≤1mm / m, the edge is essentially free from burrs and the width tolerance is within ± 0.1mm. The current domestic slitting machine the general problems: straightness can not meet the requirements, according to the Ministry of Metallurgical standard, cold-rolled strip scoliosis ≤ 3mm / m; after cutting the strip edge burr; cutting width tolerance; points After the article is not tight, missing, in particular, can not meet the requirements of heavy volume; soft material can not be cut
