Roll hitch and roll gap adjusting device of multi-roll strengthening machine

Abstract

The invention discloses a roll hitch and roll gap adjusting device of multi-roll strengthening machine, which is used for adjusting the roll gap of the roll hitch of multi-roll strengthening machine. The bearing pedestal of the working roll is connected to the bottom plate via screws; a pair of wedged irons are disposed between the bearing pedestal of the working roll and the bottom plate; the 1# adjusting bolt and 2# adjusting bolt for adjusting the wedged irons in length direction are respectively disposed on the 1# end plate and 2# end plate; the 1# end plate and the 2# end plate are respectively fixed to the bearing pedestal of the working roll via the 2# screw. After the roll is grinded, the invention does not need to increase a high-precision cushion plate with the number equal to the support roll and the invention can make the wedges irons slip to adjust the distance from the bearing pedestal of the working roll to the bottom plate only by the 1# adjusting bolt and 2# adjusting bolt. Therefore, the invention not only provides convenient and fast adjusting, but also guarantees good contact precision among the working roll, the middle roll and the support roll. More importantly, the bottom surface of the support roll pedestal does not need to be added with high-precision cushion plates of many specifications, as a result, the adjusting time and the operation cost of the equipment are reduced greatly.

Description

technical field [0001] The invention relates to the technical field of metallurgical equipment, in particular to a roll gap adjustment device for a multi-roll straightening machine. Background technique [0002] In the metallurgical industry, the multi-roller straightening machine has a considerable number of staggered straightening rollers, which can cause continuous and repeated bending deformation of the strip to eliminate wave-shaped defects of the strip and improve the quality of the strip. The core component of the multi-roll straightening machine is the straightening roll system. After the straightening machine works for a certain period, the rolls are worn and scratched and need to be ground. After grinding, the diameters of the working rolls, intermediate rolls and backup rolls become smaller and the gap increases. , the mutual contact between the rollers cannot be guaranteed. At present, the more common method is to adjust the back-up roll seat so that the back-up ...

Problems solved by technology

Since a set of roll sets is equipped with many sets of back-up roll seats, only by adding backing plates one by one on the bottom of each back-up roll seat, can the contact accuracy of the work roll, intermediate roll, and back-up roll be guaranteed, resulting in heavy workload and high cost
