Roll gap downward pressing regulation device for straightening machine

Abstract

A roll gap downward pressing regulation device for a straightening machine comprises an upper roll system, a lower roll system, an inclined wedge mechanism driving the upper roll system to move up and down, and a motor lead screw mechanism driving inclined wedges to move horizontally. Roll gap downward pressing regulation device bodies are of an inlet and outlet symmetrical structure and arranged at the left end and the right end of the upper roll system correspondingly. Servo motors are fixed to the top end of a machine frame. Driving force for making the upper inclined wedges move horizontally is provided through connection of the lead screw mechanism and the upper inclined wedges. The lower inclined wedges are matched with the upper inclined wedges and vertically move up and down in guide grooves of the machine frame. The lower roll system is fixed. Arc surfaces of the lower ends of the lower inclined wedges are in running fit with arc surfaces of the upper roll system, and therefore it can be ensured that the upper roll system rotates relative to the lower inclined wedges, parallel contact between the surfaces of the upper inclined wedges and the surfaces of the lower inclined wedges is ensured, and roll gap regulation is achieved.

Description

technical field [0001] The invention relates to the technical field of straightening machine equipment, in particular to a roll gap adjustment device for a straightening machine. Background technique [0002] Straightening is an important forming link to obtain straight metal sheets and strips, and its technology directly determines the product quality. The roller straightening machine makes the metal sheet and strip repeatedly bend during operation through the staggered arrangement of rollers. This deformation process effectively improves the straightening accuracy of the sheet and strip and eliminates residual stress. Among them, reasonable roll gap adjustment plays a vital role in the straightening quality of the strip. The widely used hydraulic cylinder adjustment device occupies a large volume and consumes a lot of energy. It is difficult to use in some small straightening equipment. For the improvement of product quality, the load of the existing adjustment device is ...

Among them, reasonable roll gap adjustment plays a vital role in the straightening quality of the strip. The widely used hydraulic cylinder adjustment device occupies a large volume and consumes a lot of energy. It is difficult to use in some small straightening equipment. For the improvement of product quality, the load of the existing adjustment device increases, resulting in increased shift error and frequent failures
