Description

Zero setting mechanism for roll gap of roll

Technical Field

The utility model relates to a rolling mill technical field specifically is a roll gap zero setting mechanism.

Background

A component of a rolling mill for plastically deforming a metal to be rolled. The shape, size and material of the rolls must be compatible with the rolling mill and the rolled product. The roll body is a working part of the roll; the roll neck is the part in contact with the bearing; is connected with a transmission device by a joint.

Roll gap control is one of core control technologies for cold-rolled plate strip processing, advanced roll gap control technologies are continuously emerging along with continuous progress of scientific technologies in recent years, the roll gap control technologies are improved day by day, equipment progress and industry upgrade of the cold-rolled plate strip industry are promoted through development of the roll gap control technologies, and production efficiency and benefits are greatly improved.

The roll gap is directly referred to as the warping degree of the plate strip, and the essence of the roll gap is the distribution of residual stress in the plate strip. If residual stress exists in the plate strip, the roll gap is poor. If the residual stress is not enough to cause the plate strip to warp, the roll gap is called as 'potential' poor roll gap; if the sheet strip is unstabilized and warped due to residual stress, the roll gap is said to be "apparent" and defective.

The roll gap adjusting mechanism of the rolling mill is used for adjusting the roll gap so as to enable a rolled piece to reach a required section size, and the upper roll adjusting device is also called a screw-down device. The roll gap adjusting mechanism of the rolling mill generally adopts a worm-worm gear, a gear device rotates four pull rods, and an upper roller and a lower roller are symmetrically adjusted relative to a rolling line under the action of a forward thread pair and a reverse thread pair of the pull rods. The roll gap adjusting mechanism is generally in interference connection with the pull rod, and when the roll gap adjusting mechanism breaks down and needs to be maintained, the roll gap adjusting mechanism needs to be detached from the pull rod.

At present, the two rolling mills for metal rolling are mostly of a fixed structure, the structure is simple, therefore, the gap between the rolls is difficult to adjust according to the size required by the rolled piece production, the zero setting operation is difficult to realize, and the applicability is relatively poor.
