Problems solved by technology

The mating surface of the straightening roller and the roller sleeve is designed as a tapered surface, which reduces the difficulty of aligning the roller sleeve and the straightening roller, but reduces the strength of the straightening roller, so it is necessary to increase the straightening roller under the same working conditions diameter to increase its strength
Guided by the guide rod and pushed to move the bracket, the manufacturing and installation requirements for the guide rod are extremely high, and it is difficult to adjust if there is a gap after use; and limited by the length of the guide rod, the stroke of the roller changer is limited, such as increasing the roll change The stroke of the car will inevitably increase the length of the guide rod, which not only increases the difficulty of manufacturing and installation, but also increases the drive side area of ​​the straightener.

Abstract

The invention is suitable for the field of rolled steel straightening and provides a roll changing gear for a cantilever-type parallel roll straightening machine. The roll changing gear comprises track frames, a transmission mechanism and a roll changing car; the roll changing car is provided with bracket elevator mechanisms; the roll changing car moves on the track frames through the transmission mechanism. According to the roll changing gear provided by the invention, multiple pairs of roll sleeves and straightening rolls on brackets can be accurately and simultaneously centered; the roll changing mode is simple and fast; the roll changing gear is also suitable for long-distance crossing and driving roll changing of the roll changing car.

Description

technical field [0001] The invention belongs to the field of steel rolling and straightening, in particular to a roll changing device for a cantilever type parallel roll leveler. Background technique [0002] Straightening technology is mostly used in the post-process of metal strip processing, which largely determines the quality level of production and finished products. In the production of the straightening machine, the straightening rollers need to be replaced frequently due to the replacement of product specifications or the wear of the roller ring. In order to improve the straightening quality, the cantilever type parallel roller straightening machine is designed with a large number of straightening rollers. In the initial design, the parallel roll leveler is designed to be at least five rolls, and now the number of rolls of the cantilever parallel roll leveler is usually nine rolls or ten rolls, or even more. In order to improve production efficiency and reduce rol...
