Axial adjusting device of rollers

Abstract

The invention provides an axial adjusting device of rollers. The axial adjusting device of the rollers aims to conveniently achieve online real-time adjustment, reliable and accurate transmission, a long service life and low noise. The axial adjusting device of the rollers comprises a servo motor fixed to a rolling machine frame. One end of the telescopic rod is connected with an output shaft of the servo motor. The rolling machine frame is further provided with a drive mechanism. The drive mechanism drives the other end of the telescopic rod to be matched with a worm arranged on the outer ring of a roller axial adjustment ring or not matched with the worm. The servo motor is directly fixed to the rolling machine frame, due to support of the rolling machine frame, the servo motor is smallin vibrating amount during work, transmission of the output shaft of the servo motor is stable, it is avoided that redundant pressure is exerted on engagement between a worm gear and the worm, engagement between the worm gear and the worm is stable, the wear extent is low, noise is low, and the service life is long.

Description

technical field [0001] The invention relates to rolling equipment, in particular to a device for adjusting the axial position of rolls in a rolling mill. Background technique [0002] When processing wire and bar, it depends on the matching notches on the rolling mill rolls that cooperate with each other. If the notches are misaligned with each other or the positions of the notches are not completely aligned with each other, the cross-sectional shape and size deviation of the rolled product will occur. And other quality problems, in severe cases, waste products will be rolled out. In view of this, it is necessary to carry out axial adjustment to a pair of rolls that cooperate with each other to ensure that the notches that cooperate with each other on the rolls are facing each other. [0003] The applicant of the present invention has previously applied for a patent titled "A Roll Axial Adjustment Device" (Patent No.: CN102310086B). The teeth on the outer ring of the axial ...

AI Technical Summary

Problems solved by technology

However, the hydraulic motor or servo motor is directly and always connected to the outer rod end of the worm, and the hydraulic motor or servo motor is supported by the worm. Vibration will inevitably occur when the hydraulic motor or servo motor is working, increasing the meshing of the worm gear The wear and tear of the components affects the service life and the noise is loud

Moreover, the hydraulic motor or servo motor rotates due to the vibration during the rolling process and the vibration of the transmission shaft between the worm and the motor, resulting in axial movement of the roll and deformation of the rolling hole shape, which will seriously affect the quality of the workpiece to be rolled
