Adjustable guide

Abstract

The invention relates to the field of rolling mill guide, in particular to an adjustable guide. The adjustable guide comprises two guide bodies which are vertically arranged and two guard plates which are correspondingly arranged up and down, wherein the two guide bodies are positioned on the left and right sides of the two guard plates; a connecting shaft group which is horizontally arranged and perpendicular to the guide bodies is connected between the two guide bodies, and consists of two connecting shafts which are arranged in parallel up and down; the two guard plates are fixedly arranged on corresponding connecting shafts respectively; a guide passage for a material to pass through is defined by the two guide bodies and the two guard plates; the guide bodies are provided with square holes of which the hole cores are arranged along the axes of the connecting shafts; square pressing blocks are arranged in the square holes; the middle parts of the pressing blocks are provided with middle holes for the connecting shafts to penetrate through; at least one plug block is arranged between the outer side walls of the pressing blocks along the horizontal direction and the inner hole walls of the square holes; a locking unit for limiting the movement of the pressing blocks along the axes of the connecting shafts is also arranged beside one pressing block. The adjustment is easy, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of rolling mill guides, in particular to adjustable guides. Background technique [0002] Guides are set at the exit or entrance of the rolling mill, and the guides play the role of supporting and guiding the materials of the rolling mill. The guide tip part of the guide is close to or attached to the rolls of the rolling mill, and the materials rolled by the rolling mill pass through the guides. Transmission, the distance between the tip of the guide and the roll is related to whether the rolling mill can roll stably. When the rolls of the rolling mill are rolling wire bars or section steel, because the wire bar or section steel is red steel with high temperature and high speed, the rolls are easy to wear, and the worn rolls need to be turned to achieve their maximum use value. The original dimensional accuracy, the size of the roll after turning becomes smaller, and the distance between the roll and the guide tip c...

Problems solved by technology

[0003] The traditional guide is fixed on the beam of the rolling mill, and the whole guide needs to be disassembled from the beam of the rolling mill, and the guide is moved so that the guide tip of the guide can be moved to the best position with the roll of the rolling mill to ensure the stability of the rolling mill Rolling, this adjustment method is labor-intensive and time-consuming, and the labor intensity of the operator is extremely high
