Problems solved by technology
Because the traditional uncoiler uses the hydraulic cylinder as the driving force to realize the radial expansion and contraction movement of the fan-shaped plate, the oil leakage phenomenon is serious and the environmental pollution is relatively large. In addition, the manufacture of the upper quadrangular pyramid sleeve is relatively difficult and the manufacturing process is complicated. Equipment manufacturing and maintenance difficulties

The invention discloses a hot rolled steel coil decoiler, and aims to provide a hot rolled steel coil finishing machine for metallurgical industry. The hot rolled steel coil decoiler has the functionsof tensioning and clamping, unwinding and rotating the hot rolled steel coil. The hot rolled steel coil decoiler comprises main components and parts such as a base seat, a gearbox, a drive shaft assembly, an intermediate shaft assembly, a decoiling device, and a worm shaft assembly. According to the technical scheme, a geared motor is used as a prime motor for tightening and clamping action to supply power for the tightening and clamping action of the unwinding device through the drive shaft assembly and the intermediate shaft assembly; a worm and gear is used as a reduction transmission mechanism to supply power for the rotating main motion of the steel coil; and by means of the decoiler, the tension of the steel coils can be effectively controlled, the synchronism of constant velocity radial movement of the four sector plates is good, the structure is simple, the manufacturing is easy, the maintenance is convenient, and the economical efficiency is good.
Description
technical field [0001] The invention relates to a hot-rolled steel coil finishing mechanical equipment in the field of metallurgy, in particular to a hot-rolled steel coil uncoiler. Background technique [0002] The known hot-rolled coil uncoiler is one of the special equipment for metal plate leveling, and can form uncoiling, leveling, shearing production lines and other plate product production lines together with related equipment. One of the functions of the uncoiler is to uncoil while maintaining the tension of the strip. At present, the commonly used uncoilers in China use a speed-regulating motor to drive the reel shaft to provide the main power for the uncoiler after being decelerated by a gearbox, and the tension force during uncoiling mainly uses the following mechanism: a square pyramid sleeve is arranged on the reel shaft , the quadrangular pyramid sleeve connects the four fan-shaped plates through the inclined dovetail grooves on the four end faces, and each fa...
