Description

Technical Field

[0001] The utility model belongs to the technical field of cold-rolled steel uncoiling machine reels, in particular to a cold-rolled steel coil uncoiling machine reel. Background Art

[0002] The uncoiler is an important equipment on the continuous strip production line. Its main function is to expand and tighten the strip coil, and at the same time open the strip head and send it to the production line to realize the uncoiler function. It is mainly composed of a reel and a gear box. The reel mainly includes a pyramid shaft, a fan-shaped plate and other mechanisms. During the uncoiling process of the cold-rolled strip, the steel coil is first transported to the uncoiler reel by the coiling trolley. The reel drives the sleeve and the fan-shaped plate to slide along the inclined surface through the rotating cylinder, so that the reel expands and the uncoiler performs uncoiling.

[0003] After searching, the patent with application number 201220444101.4 discloses a coiler and a coiler. The patent ensures the coil expansion of the coiler by arranging a support plate on the expansion frame and an expansion core on the outer surface of the support plate, thereby avoiding the phenomenon of coil falling off and affecting subsequent production. The working principle is: the expansion and contraction oil cylinder drives the piston rod to retract, the piston rod drives the expansion frame rear sleeve to retract, the expansion frame rear sleeve drives its own expansion frame plate to rotate, and at the same time, under the support of the expansion frame plate on the expansion frame front sleeve, the expansion and contraction support plate expands outward along the long hole of the expansion frame guard plate. The fixing method of the steel coil using this structure, on the one hand, has more components as a whole, is more troublesome to install, and has a higher production cost. In addition, in actual use, since the force direction of the expansion and contraction rear sleeve 8 is axial, there may be movement, which causes the steel coil to loosen after being fixed and has poor stability.
