Asbestos paper wrapping device used for cooling after roller surfacing

Abstract

The invention relates to an asbestos paper wrapping device used for cooling after roller surfacing. The device comprises a bottom plate. A rolling mechanism used for mounting a roller is arranged in the middle of the bottom plate. A conveying and cutting mechanism used for mounting asbestos paper is arranged on the front portion of the bottom plate. A self-adaption pressing mechanism is arranged on the rear portion of the bottom plate. The rolling mechanism comprises a left vertical plate, a right vertical plate, a chuck, a motor, an ejection pin cylinder and pushing mechanisms. Each pushing mechanism comprises a mounting plate, a horizontal pushing air cylinder, an adapting plate, a spring pressing strip, a rack, a big gear, a small gear and an arc-shaped pressing plate. The conveying andcutting mechanism comprises a reel, supports, a rotary motor, a long cutting board, a lifting air cylinder and a cutting groove plate. The self-adaption pressing mechanism comprises forward pushing air cylinders, a supporting plate, a long rolling shaft, air cylinders, loading plates, guide rods, mounting bases, short rolling shafts and springs. By means of the asbestos paper wrapping device usedfor cooling after roller surfacing, the labor intensity can be relieved, the working efficiency is improved, the roller can be uniformly cooled, an internal stress eliminating effect is improved, andcooling treatment of the roller after surfacing is facilitated.

Description

technical field [0001] The invention relates to the technical field of mechanical devices, in particular to an asbestos paper wrapping device for cooling rolls after surfacing. Background technique [0002] The roll is an important part of the rolling mill in the rolling mill. It uses the pressure generated when the roll rolls to roll the steel. It is mainly subjected to dynamic and static loads, wear and temperature changes during rolling. When the roll is damaged, it is generally used to repair and manufacture the roll by surfacing welding. The roll should be cooled slowly and evenly after surfacing, so as to minimize the internal stress caused by the metal shrinkage and uneven heating of the surfacing layer. After wrapping asbestos paper on the roll body and roll neck of the roll, it is cooled. [0003] However, at present, when wrapping asbestos paper on rolls in the workshop, it is necessary to manually press the initial end of the asbestos paper on the roll to roll t...

AI Technical Summary

Problems solved by technology

[0003] However, at present, when wrapping asbestos paper on rolls in the workshop, it is necessary to manually press the initial end of the asbestos paper on the roll to roll the first circle, and cut the wrapped asbestos paper, which has high labor intensity and low work efficiency. It is impossible to ensure that the asbestos paper is pressed tightly on the roll during wrapping, which is not conducive to achieving uniform cooling, and the effect of internal stress relief is reduced, which is not conducive to the cooling treatment of the roll after surfacing
