A hydraulic locking device is arranged between a vertical roll frame and the operational lateral frame, a hydraulic roll change device is arranged on one side of the driving lateral frame, and a lifting roll-collecting basket is arranged on one side of the operational lateral frame. Compared with a current universal mill, the utility model has fast and convenient roll change and simple operation, the roll bearing is far from the high temperature and attack of rolled pieces, and the service life of the roll bearing is prolonged. Compared with a roller-and-ring mandrel of a bearing, the vertical roll diameter strength is high and is not easy to deform, and the precision H-shaped steel products which are rolled by the utility model is high.

Description

Universal mill
Technical field:
The utility model relates to metallurgical rolling machinery, relates in particular to the high rigidity universal mill of a kind of fast roll changing.
Background technology:
The characteristics of universal mill are that an a pair of horizontal roller and an opposite roller axis are positioned on the same vertical plane, and each roll is rolled along direction up and down simultaneously to rolled piece.At home, produce the milling train of H shaped steel, current have connect four kinds of board-like, DANELI chuck mode, the red circle formula of POMINI and DEMAC memorial archway formulas, yet the subject matter that these universal mills exist is that the version of edger roll is roller-and-ring, and roll bearing is set in the roll, and bearing directly bears high temperature and shock loading like this, oil film is subjected to high temperature and destroys, cause roll bearing often to damage, connect board-like universal mill roll change in addition and bother very much, approximately need more than eight hour.
Summary of the invention:
In order to overcome existing universal mill above shortcomings, it is a kind of easy to operate that the utility model provides, the edger roll long service life, and fast roll changing, the energy high precision rolling goes out the universal mill of H shaped steel.
Realize that the technical scheme that above-mentioned purpose adopts is: a kind of universal mill, by the fore side frame, the transmission side frame constitutes whole rolling mill support, last plain-barreled roll electric screw down gear is loaded on the support top, the electronic pressuring upper device of following plain-barreled roll is loaded on the support bottom, last plain-barreled roll assembling and the assembling of following plain-barreled roll are arranged in the base framework, two edger roll assemblings are separately positioned between two plain-barreled roll assemblings, its bearing be divided into edger roll on, following two roller neck ends, be provided with hydraulic locking apparatus between edger roll framework and the fore side frame, transmission side frame one side is provided with the hydraulic pressure changing rig, and fore side frame one side is provided with the receipts roller basket that can lift by crane.
The universal mill that provides according to this case, compare with existing universal mill, because two flat rods and two edger rolls all are installed in the support of being made up of transmission side frame and fore side frame, with hydraulic locking apparatus edger roll framework and support are locked, form the sealing profit wire loop of edger roll roll-force, therefore satisfy convenient and swift roll change under the rigidity requirement, characteristics easy and simple to handle, its roll change process is: hydraulic locking apparatus is opened, with the hydraulic pressure changing rig is (comprising two horizontal roller systems and two edger roll roller systems) to be pushed into to receive in the roller frame from support and to hang away whole roller, and the roll change process only needs more than 30 minute; Because roll bearing is put into the roll both sides, away from the high temperature and the impact of rolled piece, so the roll bearing long service life.In addition, compare the mandrel of roller-and-ring structure dress bearing, edger roll diameter intensity height, not yielding, the H shaped steel product precision height that rolls out.

The specific embodiment:
Provide a specific embodiment of the present utility model below in conjunction with accompanying drawing:
As shown in Figure 1 and Figure 2, a kind of universal mill, by last plain-barreled roll electric screw down gear 1, transmission side frame 2, go up plain-barreled roll assembling 3, roll mandrel to adjusting bolt 4, hydraulic locking apparatus 5, plain-barreled roll assembling down, 6, down plain-barreled roll electric screw down gear 7, hydraulic pressure changing rig 8, edger roll assembling 9, edger roll electric screw down gear 10, manual fine-tuning device 11, fore side frame 12, receive compositions such as roller basket 13.Fore side frame 12, transmission side frame 2 constitute whole rolling mill support, last plain-barreled roll electric screw down gear 1 is loaded on the support top, the electronic pressuring upper device 7 of following plain-barreled roll is loaded on the support bottom, last plain-barreled roll assembling 3 and following plain-barreled roll assembling 6 are arranged in the base framework, two edger roll assemblings 9 are located at respectively between two plain-barreled roll assemblings, hydraulic locking apparatus 5 is arranged between edger roll framework and the fore side frame 12, hydraulic pressure changing rig 8 is positioned at transmission side frame 2 one sides, and the receipts roller basket 13 that can lift by crane is positioned at fore side frame 12 1 sides.
Hydraulic locking apparatus 5 in the present embodiment as shown in Figure 3, its hydraulic cylinder 1 is fixed on the fore side frame 12, its piston rod front end is equipped with plate 15, the corresponding locking of draw-in groove that is provided with on this plate 15 and the standing roller frame 16.
