The pinch roll device comprises a driving motor, a reducer and a pinch roll main body; the driving motor is connected with the reducer by a crown gear coupling; the reducer is connected with the pinch roll main body by a universal shaft joint; the pinch roll main body comprises a machine base, and an upper roll and a lower roll both of which are arranged on the machine base; the upper roll is arranged on an upper beam of the machine base by a bearing pedestal, while the lower roller is arranged on a lower beam of the machine base; both ends of a clamping cylinder are respectively hinged with the upper beam and the lower beam; and the other end of the lower beam is hinged with a lifting cylinder. The upper roll and the lower roll in the pinch roll device provided by the invention are adjustable, the lower roll is supported by the lifting cylinder, when the billet specification is changed, the elevation of the surface of the lower roll is adjusted to the required position by adjusting the extension elongation of a piston rod of the lifting cylinder, so as to guarantee consistent billet centre line and rolling centre line.
Description
Technical field
The present invention relates to the adjustable pinch roll apparatus of a kind of up-down rollers.
Background technology
In the pressure water on modern rolling steel production, the milling train steel billet of better nipping for ease goes to toward a pinch roll is set at first rolling mill of milling train unit.Rolling centerline is fixing often; And the steel billet specification that gets into milling train can change along with the variation of product specification; The roll surface absolute altitude of workplace distance between the upper and lower roll of pinch roll and lower roll also changes thereupon like this; Therefore require the equal scalable in position of the top roll and the lower roll of pinch roll apparatus, match to realize steel billet center line and the rolling centerline of sending into milling train.
Existing pinch roll great majority are fixed for lower roll, and the top roll position leans on cylinder to regulate.Therefore, when the steel billet specification changes, need guarantee the consistent of steel billet center line and rolling centerline through the adjustment tile height of adjustment lower roll, it operates inconvenient, and efficient is not high yet.
Summary of the invention
For overcoming above-mentioned defective, the purpose of this invention is to provide the adjustable pinch roll apparatus of a kind of up-down rollers, can guarantee that center line and the rolling centerline when steel billet gets into milling train is consistent, easy to operate, efficient is high.
For achieving the above object; The adjustable pinch roll apparatus of a kind of up-down rollers of the present invention comprises drive motors, reductor and pinch roll main body, wherein; Drive motors connects reductor through crown gear coupling; Reductor connects the pinch roll main body through Hooks coupling universal coupling, and said pinch roll main body comprises support and be located at top roll and the lower roll on the support that said top roll is installed on the upper beam of support through bearing block; Lower roll is installed on the underbeam of support through another bearing block, put the beams in place and an end of underbeam hinged with support respectively; Also comprise clamping hydraulic cylinder and lifting hydraulic cylinder, wherein, the two ends of clamping hydraulic cylinder are hinged with upper beam and underbeam respectively, and the underbeam other end and lifting hydraulic cylinder are hinged, and the lifting hydraulic cylinder other end is fixed in the support of support bottom.
Further, be provided with position sensor in the said lifting hydraulic cylinder.
Further, said support two ends all are equipped with the adjusting bolt.
Beneficial effect of the present invention is:
1, center line and rolling centerline in the time of can guaranteeing steel billet entering milling train are consistent---because lower roll is supported by lifting hydraulic cylinder; When the steel billet specification changes; The extension elongation of adjustable lifting hydraulic cylinder piston rod; Thereby regulate lower roll roll surface absolute altitude to the position that requires, guaranteed that the steel billet center line is consistent with rolling centerline.
2, embedded position sensor in lifting hydraulic cylinder can be adjusted according to the production product specification automatically, and is easy and simple to handle, and automaticity is high, and efficient is high.
3, when not needing the pinch roll clamping to send steel, the roller that lower roll can be useed approach table automatically as uses, and assists and send steel, plays the effect of transportation roller.
Description of drawings
Fig. 1 is the front view of the adjustable pinch roll apparatus of the described up-down rollers of the embodiment of the invention;
Fig. 2 is the side view of the adjustable pinch roll apparatus of the described up-down rollers of the embodiment of the invention.
The specific embodiment
Below in conjunction with Figure of description the present invention is done further description.
