设计简介
摘要
液压剪板机自动生产线中第一道工序就是开卷。这就用到了开卷机,开卷机是用来支撑钢卷、回转钢卷的。随着对开卷机速度和板面质量的要求,开卷机的型式已由箱式开卷机,无胀缩卷筒开卷机等类型,逐步发展过渡到胀缩卷筒式开卷机。目前市场上开卷机的型式有很多种,如单卷筒悬臂式.双卷筒回转式.双柱头开卷机。它们共同特点都是涨缩卷筒式开卷机。采用胀缩卷筒式开卷机的优点是:其设备配置较为简单,主要由传动系统及胀缩卷筒、压紧辊和支撑等装置组成。
根据现场调研,原开卷机的张力较小,现增加了带钢的张力,进行了主要零件的强度计算。该开卷机保证开卷时恒定张力,保证开卷线速度恒定,从而提高了带钢的表面质量。而且具有对中调节功能,即在上卷和工作过程中,始终保证带材中心线与下道机组中心线重合,减少带钢的翘曲现象,从而保证剪板的正常进行,提高了带钢产品质量。

Abstract
The first step of hydraulic plate shears automatic production line is open- book. This will use the uncoiler, uncoiler is used to support steel coil, rotary steel coil. As the uncoiler speed and surface quality request, uncoiler type already developed from box uncoiler, without swell-shrink reel of decoiler type etc, and gradually developed transition to swell-shrink prefabricated uncoiler. Now on the market of decoiler type has a lot of kinds, such as single reel cantilever. Double drum rotary. Double the stigma of decoiler. Their common characteristic is all decoiler prefabricated rose shrinkage. The advantage of adopting swell-shrink prefabricated uncoiler in equipment configuration is simple, and mainly by the transmission system and swell-shrink drum, pressure roller and supports device component.
According to the field investigation, the tension of original fetching machines is relatively small, increase the tension with steel now,the intensity of carrying on the major part is calculated.The uncoiler guarantee open-book invariableness tensile, guarantee the open-book rotational speed, thereby improving the strip surface quality. And it has regulating function , be in namely roll-up and working process, always guarantee strip with road centerline centerline coincidence, reduce strip unit to ensure the warp phenomenon, the normal shear, improved the surface quality with steel.
