Straightening roll adjusting device

Abstract

The invention relates to a straightening roll adjusting device which is applied to a high-strength ultrathin plate strip finishing line. The straightening roll adjusting device comprises a support, wherein a lower roll seat is arranged at the lower part of the support; a plurality of lower straightening rolls which are distributed at intervals are rotatably arranged on the lower roll seat; the outer surfaces of the lower straightening rolls are located on the same plane; upper straightening rolls are arranged at the upper part of the support; a straightening space is formed between the upper straightening rolls and the lower straightening rolls; each upper straightening roll is correspondingly arranged on one upper roll seat; screw rods are rotatably arranged on the support; the number of the screw rods and the number of the upper roll seats are identical; the screw rods and the upper roll seats are matched in a one-to-one way; a connecting rod is vertically arranged corresponding to each screw rod; one end of each connecting rod is correspondingly connected to one upper roll seat; the other end of each connecting rod is provided with a worm gear which is matched with the corresponding screw rod through transmission; the connecting rods are in screw thread fit with the worm gears. The straightening roll adjusting device is simple in structure, reasonable in design, and capable of adjusting the height difference among the upper roll seats, ensuring that the working faces of the upper straightening rolls are always located on the same plane, and meeting the finishing and straightening requirements of a high-strength ultrathin plate.

Description

technical field [0001] The invention relates to the field of finishing and straightening of metallurgical cold-rolled strips, in particular to a straightening roller adjustment device used in high-strength ultra-thin strip finishing lines. Background technique [0002] At present, the multi-roll leveling machine in the strip finishing line, such as nine-roll straightening, generally adopts the form of upper four rolls and lower five rolls. The two ends of the upper four rolls are integral, and the two ends of the lower five rolls are integral. The straightening machine with this structure fully satisfies the finishing and straightening of ordinary specification strips, but there are problems in the straightening of high-strength ultra-thin strips. The working surface of the straight roller and the working surface of the lower straightening roller are on the same plane, and the height difference is allowed to be no more than 0.05mm in the whole length of the roller body, that...

Problems solved by technology

The straightening machine with this structure fully satisfies the finishing and straightening of ordinary specification strips, but there are problems in the straightening of high-strength ultra-thin strips. The working surface of the straight roller and the working surface of the lower straightening roller are on the same plane, and the height difference is allowed to be no more than 0.05mm in the whole length of the roller body, that is, the flatness of the working surface of the upper and lower straightening rollers is less than 0.05mm

At present, it is difficult to ensure the assembly accuracy of the roll system due to the machining accuracy, fit clearance, and accumulated errors of the parts in the structure straightening machine.
