Abstract
The utility model relates to accessory equipment in the production of rolled steel, particularly a special device for dismantling a roller bearing for a rolling mill. The utility model is composed of a machine frame (1), a hydraulic cylinder (2), a movable clamp board (3) and a roller trolley (4), wherein the hydraulic cylinder is fixed at one end of the machine frame; the movable clamp board and the hydraulic cylinder are arranged in parallel; the movable clamp board can slide on the machine frame, and the sliding direction of the movable clamp board is vertical to the hydraulic cylinder; the roller trolley and the hydraulic cylinder are arranged on a beeline, and the roller trolley can move on the beeline. The dismantling work is finished by that the roller with a burnout bearing is arranged on the roller trolley which is moved to get close to the hydraulic cylinder, the burnout bearing on the roller is locked in a sliding manner the movable clamp board, so that the hydraulic cylinder is driven to act to pack out the roller which is separated from the bearing. The utility model has the advantages that the work process is quick and convenient, the roller can not be damaged, the production efficiency is improved, and the production cost is reduced.
Description
Technical field: the utility model relates to a kind of steel rolling production auxiliary equipment, particularly dismantles the isolated plant of rolling mill roll bearing.
Background technology: at present, rolling mill roll bearing burnout failure often takes place in steel rolling is produced, and need in time to change roll bearing, but bearing and roll after burning is stuck, be difficult to dismounting, owing to there is not special dismounting equipment, people have to cut with gas welding, and are not only time-consuming but also require great effort, also cause roll to scrap easily, inefficiency, influence is produced, and increases cost.
The utility model purpose provides a kind of isolated plant of dismantling roll bearing, finishes roll bearing dismounting task rapidly, does not damage and rolls rod, solves the problems referred to above that exist in the background technology.
The utility model content: dismounting roll bearing isolated plant is made up of frame, hydraulic cylinder, movable clamp, roll dolly, hydraulic cylinder is fixed on an end of frame, movable clamp and hydraulic cylinder are arranged in parallel, movable clamp slides on frame, glide direction is vertical with hydraulic cylinder, roll dolly and hydraulic cylinder are arranged point-blank, and are moved on this straight line.
Adopt the utility model, the roll that burns bearing is placed on the roll dolly, and mobile roll dolly is near hydraulic cylinder, and slip activity clamp blocks the bearing that burns on the roll, the action of driving hydraulic cylinder ejects roll, separates with bearing, finish dismantlement work, convenient rapidly, do not damage roll.
The utlity model has the convenient characteristics such as bearing of rapidly, not damaging of rational in infrastructure, dismounting roll bearing, enhance productivity, reduce production costs.
Description of drawings: accompanying drawing is the utility model example structure schematic diagram.
Among the figure: frame 1, hydraulic cylinder 2, movable clamp 3, roll dolly 4.
The specific embodiment:, further specify the utility model by embodiment below in conjunction with accompanying drawing.
In an embodiment, dismounting roll bearing isolated plant is made up of frame 1, hydraulic cylinder 2, movable clamp 3, roll dolly 4, hydraulic cylinder is fixed on an end of frame, movable clamp and hydraulic cylinder are arranged in parallel, for being fit to the roll bearing of dismounting different-diameter, movable clamp slides on frame, and glide direction is vertical with hydraulic cylinder, roll dolly and hydraulic cylinder point-blank and move on this straight line.The roll that burns bearing is placed on the roll dolly, mobile roll dolly is near hydraulic cylinder, the jack of hydraulic cylinder is regulated slip activity clamp on roll mandrel, the bearing that burns on the roll is blocked, the action of driving hydraulic cylinder, roll is ejected, separate, finish dismantlement work with bearing, convenient rapidly, do not damage roll.
