摘要：

针对悬臂四棱锥胀缩结构的卷筒的卷重能力低，且使用中容易出现夹卷、卷筒不涨、滑楔频繁断裂、钢卷内圈硌伤或带钢出现压痕及钳口缸漏油等故障，分析了故障产生的原因，主要是卷筒的悬臂四棱锥胀缩结构存在一定缺陷。通过结构改进，采用内楔形块带动外楔形块、外楔形块带动扇形板的“三斜楔、三扇形板”结构及无缝配合卷筒、自润滑等设计与制造技术，不仅提升了卷重能力，还消除了间隙圆，使卷筒表面形成一光滑圆柱表面，避免了卷筒表面对钢带内圈的硌伤，最大卷重增加了50%，而卷筒直径下降了15%，经济效益显著。

Many problems appeared in the application of the traditional reel, such as the reel of the cantilever rectangular pyramid swell-shrink structure was not only the low coiling weight ability, but also prone to folding roll, rolling without bulging, frequent sliding wedge fracture, injuring inner steel ring or strip indentation as well as jaw cylinder leaking oil. Then, the causes of failure were analyzed, mainly because that there were some defects existed in the cantilever rectangular pyramid swell-shrink structure of reel. Through improving structure and applying design and manufacturing technologies, such as the three-wedge and three-sector plate structure of the inner wedge block driving the outer wedge block and the outer wedge block driving the fan-shaped plate, the seamless fitting reel and self-lubricating etc., the coiling weight ability is improved, and the gap circle is eliminated to make the reel surface form a smooth cylindrical surface and prevent injuring inner steel ring produced by the reel surface. Thus, the largest coiling weight increases by 50% and the reel diameter decreases by 15%, which shows a remarkable economic benefit.
