针对普通四棱锥卷取机卷筒膨胀开时,扇形板间隙过大,易压伤内层带钢的问题,八棱锥式卷取机的卷筒增加了四对闭合条(扇形附板)与斜楔块,卷筒胀缩时,附板随扇形板胀大或缩小,填补了扇形板与扇形板之间的间隙.并分析了八棱椎卷取机的结构特点,其传动结构简单,胀缩机构合理,能明显改善钢板卷取质量,值得推广.%To solve the problems of the strip steel crushing caused by excessive clearance between sector plates when the coiling block of the common rectangular pyramid recoiling reel expands, a octahedral pyramid recoiling reel is proposed. The four-pairs of fan-shaped attachment plates and tilt wedge blocks are added on the coiling block of octahedral pyramid recoiling reel. When the coiling block expands or shrinks, the fan-shaped attachment plates do the same action with the sector plates. The function fills up the gap between the sector plates. The structural characteristics of the octahedral pyramid recoiling reel are analyzed. The octahedral pyramid recoiling reel has the advantages of simple transmission structureand rational expanding-shrinking mechanism, and can evidently improve the quality of steel strip.
