Background technology
At present in the heavy section steel production line, for can rolling large H-shaped steel, large-scale I-steel, large-scale rail and steel sheet pile, need to adopt the shape rolling mill of omnipotent form.Verticle roll unit is the part of H-Beam Rolling Mill milling train, plays the rolling effect to the blank width direction in rolling process.The shaped steel universal rolling mill vertical roll device of domestic and international Design and manufacture all can only be used for rolling medium and small section, and also had certain problem on version in the past.The problem that exists mainly comprises: the sealing effectiveness of roller is bad, and water and iron scale often enter roller inside, damages bearing; The lubricant effect of roller is bad, and bearing is low service life; The axial force that bearing can bear is low, and rolled steel sheet pile is difficulty relatively.Along with the development in epoch, the demand of heavy section steel is increasing, for existing problem in the above-mentioned prior art, and a kind of novel heavy section steel universal rolling mill vertical roll device of research and design, existing problem is very necessary in the prior art thereby overcome.
Summary of the invention
In view of existing problem in the above-mentioned prior art, the purpose of this utility model is a kind of novel heavy section steel universal rolling mill vertical roll device of research and design, can not rolling heavy section steel thereby solve traditional verticle roll unit, the sealing of roller and lubricant effect is bad, the rolled steel sheet pile problem such as difficulty relatively.
Heavy section steel universal rolling mill vertical roll device described in the utility model is comprised of edger roll assembling device, edger roll guider, rack-mounted device, side-pressing device.Described verticle roll unit is driven roll, roller in edger roll assembling device traffic direction with stocking when stocking is rolling rotates, bearing is installed in roller inside, and whole verticle roll unit is to put together on the duo mill frame by the pre-stressed bolt in the rack-mounted device.The edger roll assembling device is installed in the edger roll guider.Edger roll guider and side-pressing device are installed in the rack-mounted device.
Side-pressing device described in the utility model is comprised of hydraulic motor, reductor and side pressure screw, the adjustment of roll gap is to add worm-gear speed reducer by the fluid motor-driven gear in the side-pressing device in the verticle roll unit, and drives edger roll guider that the edger roll assembling device is housed by the side pressure screw and slide at rack-mounted device and realize.
Bearing described in the utility model is installed in roller inside, and bearing adopts two single-row tapered roller bearings to install back-to-back, and bearing outer ring is with roller turn, and inner ring is motionless.
Heavy section steel universal rolling mill vertical roll device described in the utility model is comprised of edger roll assembling device, edger roll guider, rack-mounted device, side-pressing device.Roll bearing adopts two single-row tapered roller bearings to install back-to-back, bears radial rolling power and the axial force of vertical miller.Bearing is installed in roll inside, and bearing outer ring is with roller turn during steel rolling.Edger roll guider, side-pressing device etc. are installed on the rack-mounted device.Frame puts together on the duo mill frame by prestressed draw-bar, bears the roll-force of vertical miller during steel rolling.Dress edger roll assembling device drives roll by slide plate and slides in frame in the guider when opening degree changes.Side-pressing device is installed in the rack-mounted device, adds worm-gear speed reducer transmission side pressure screw and nut by hydraulic motor by gear, thereby regulates the opening degree of vertical miller roll.Roll balance adopts spring balancing.
The technical scheme that its technical problem that solves the utility model adopts is: the size of roller and bearing is strengthened, and roller adopts the material that can adapt to rolling heavy section steel, and the bearing inclination angle increases, and can bear very large axial force.Two turning lip oil sealings of installing are back-to-back adopted in the sealing of roller, and roll bearing adopts oil-air lubrication.
The beneficial effects of the utility model are: can rolling large H-shaped steels, large-scale I-steel, large-scale rail and steel sheet pile, improved sealing and the lubricated form of roller.
