An Eccentric Pressing Mechanism of Universal Rolling Mill

Abstract

The invention relates to a screw down mechanism of a universal rolling mill, and belongs to the technical field of shape steel universal rolling mill equipment. According to the technical scheme, the screw down mechanism comprises horizontal rollers, vertical rollers, horizontal roll bearing pedestals, vertical roll supports (4), stand columns (5), horizontal roll screw down devices (6) and vertical roll side screw down devices (7); the horizontal roll bearing pedestals and the vertical roll supports (4) are connected in a fastened mode through the stand columns (5), the horizontal rollers comprise the upper roller (1) and the lower roller (2), the vertical rollers comprise the left vertical roller (8) and the right vertical roller (3), the axis of the upper roller (1), the axis of the lower roller (2), the axis of the left vertical roller (8) and the axis of the right vertical roller (3) are located in one vertical plane, the upper roller (1) is provided with the horizontal roller screw down devices (6), and the left vertical roller (8) and the right vertical roller (3) are provided with the vertical roller side screw down devices (7) which have the same structure. The screw down mechanism has the advantages that bounce of the horizontal rollers and the vertical rollers in the shape steel rolling process can be effectively inhibited, the rolled piece size can be better controlled, and the product quality can be guaranteed.

Description

technical field [0001] The invention relates to a depressing mechanism of a universal rolling mill, in particular to a depressing mechanism of a high-strength H-shaped steel universal rolling mill, and belongs to the technical field of shaped steel universal rolling mill equipment. Background technique [0002] High-strength new light and thin H-shaped steel is a new product and new material that has just emerged in the H-shaped steel product family in recent years. Compared with ordinary H-shaped steel, within its load-bearing application range, high-strength new light and thin H-shaped steel has the characteristics of "lightness and thinness", light weight, less metal consumption, metal saving, good rigidity performance, and more environmentally friendly. Compared with similar welded H-beams, it not only has superior internal performance, but also has the advantage of low cost. At present, due to the high difficulty of rolling, the domestic production of new high-strength...

AI Technical Summary

Problems solved by technology

At present, due to the high difficulty of rolling, the domestic production of new high-strength profiles is small and the specifications are small, which is far from meeting the needs of domestic and foreign markets, and its added value is much higher than that of ordinary profiles.

The existing ordinary universal rolling mill has poor precision and large bounce of the horizontal roll and vertical roll during the rolling process, which cannot meet the production demand
