Abstract：

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.
