Integral type rolling machine axial adjusting device

Abstract

The invention provides an integral type rolling machine axial adjusting device, comprising a rolling machine upright (1), a roller bearing block (3), multiple cup head bolts (4) which are inserted into a through hole (5) of the rolling machine upright (1), an integral type axial pressure plate (6) used for fixing and adjusting the roller bearing block (3) and multiple flat hole slots (7) which are formed on the integral type axial pressure plate (6), wherein the integral type axial pressure plate (6) is sheathed on the multiple cup head bolts (4) which penetrate through the through hole (5) of the rolling machine upright by virtue of multiple flat hole slots (7), the multiple cup head bolts (4) are respectively added with half cylindrical pads (8), and the half cylindrical pads are respectively fastened and located by virtue of nuts (9).

Description

technical field [0001] The invention relates to the technical field of steel rolling machinery, in particular to an integral rolling mill axial adjustment device. Background technique [0002] In order to maintain the correct position of the roll pass, it is necessary to move or fix the roll axially and bear the axial force and rolling torque. Therefore, on the outer side of the column of the rolling mill, the parts corresponding to the roll bearings are respectively equipped with axial adjustment devices, which are generally arranged in pairs or singly. The purpose of installing the axial adjustment device is to adjust the axial position of the rolls, to ensure the alignment of the inlet and outlet guides and the working pass, so as to control the shape, size and flatness of the rolled piece. [0003] At present, the axial adjustment device of the section steel rolling mill is a split type, which is divided into three types: upper roll, middle roll and lower roll, and the ...

AI Technical Summary

Problems solved by technology

The disadvantages of this structure are: a. The positioning bolts are positioned with nuts 15 from the inside of the column of the rolling mill. Due to the influence of guide devices such as beams, the nuts cannot be tightened during the production process, and the operation is difficult; b. The nuts are easily loosened under force. The fastening screws frequently bear axial impact force, the thread fails, and the transmission system becomes unstable, causing the torx joint shaft to collide with the roll head, the material shape of the adjacent rolling mill is twisted, and collides with the inlet and outlet guides and equipment; c, the pin of the positioning bolt Holes, pin shafts, and adjusting pressure plates have a large fit gap, and the positioning bolts cannot be fixed on the column of the rolling mill; d, the structure is complex, the operation is inconvenient, and the labor intensity is high, and the rolling mill only plays the role of transmitting torque, and there is no need to adjust the shape of the material; e, process accidents If there are too many, the transmission shafts impact each other, which will aggravate the wear of the plum blossom sleeve, lead to process accidents such as bald casing, deformation of the roll head, interrupt continuous production, and increase process rolling waste.
