Adjustable combined sliding guiding and guarding device

Abstract

The invention discloses an adjustable combined sliding guiding and guarding device which comprises a rear horn mouth, a vertical plate and a base plate, wherein a left wear-resistant plate and a right wear-resistant plate which are detachable are arranged inside the vertical plate, a detachable lower wear-resistance plate is arranged at the upside of the base plate, a detachable upper pressing plate is arranged at the upside of the vertical plate, and the fixing positions of the wear-resistant plates can be adjusted horizontally along the guiding direction. When the adjustable combined sliding guiding and guarding device is used, the wear-resistant plates and the upper pressing plate can be replaced to avoid localized wear and damage of the guiding and guarding device and reduce the consumption of the guiding and guarding device; the thickness of a gasket is increased or decreased to change the dimension of the cavity of the guiding and guarding device so as to meet the requirements of different rolling schedules; and the distance from the front ends of the wear-resistant plates to a roller can be adjusted through selecting the installing and fixing positions of the wear-resistant plates so that the requirements of groove rolling process and non-groove rolling process can be met, the requirements of different rolling stages, different roller diameters and different models of rolling mills on the installation dimension of the guiding and guarding device can be met, and the guiding and guarding device has high adaptability and universality.

Description

technical field [0001] The invention relates to a component of a roughing and intermediate rolling mill used for bar and wire production, in particular to a sliding inlet guide device for a flat rolling mill. Background technique [0002] In the production of rods and wires, in order to prevent rolling process failures such as square off and torsion during the rolling process, a guide device specially used to induce the rolled piece is required. The rolling guide device is divided into rolling guide and sliding guide. The sliding guide has the characteristics of simple structure and low cost, and is widely used in rough and medium rolling mills for rods and wires. Rolling mills are divided into flat rolling mills and vertical rolling mills. Steel rolling production practice shows that for flat rolling mills, the left and right sides and the bottom surface of the sliding inlet guide are more severely worn. [0003] In the production of rods and wires, due to the different p...

AI Technical Summary

Problems solved by technology

[0003] In the production of rods and wires, due to the different product structures, the rough and medium rolling units are equipped with grooveless rolling and groove rolling processes at the same time. The existing integral and combined guide devices cannot meet the requirements of groove rolling and grooveless rolling at the same time. Manufacturing process requirements, need to be equipped separately, resulting in increased cost

[0004] The existing integral guides are easily scrapped and replaced due to partial wear or damage. Although the existing combined guides have the characteristics of adjustable guide cavity size, their installation positions are fixed and cannot be adjusted.
