Abstract
The utility model discloses a centering device of a roughing mill. The centering device comprises a motor, a lead screw, a base and guide rollers. An output end of the motor is connected with one end of the lead screw, and the guide rollers which are arranged on two sides of a metal strip on the base are disposed on the same lead screw. The centering device has the advantages that the two guide rollers on the two sides of the metal strip are driven by the single motor to perform centering operation simultaneously, a centering position is accurate, the rolling precision is improved, the guide rollers are shifted, guided and positioned via guide columns and guide sleeves, guiding and positioning effects are stable, and a centering effect is further improved.
Description
Technical field
Utility model relates to the Mill Technology field, especially relates to a kind of roughing mill centralising device.
Background technology
In metallurgy industry, the metal made-up belt generally first by the roughing mill roughing, passes through finishing mill finish rolling again when rolling.The metal made-up belt will carry out the centering operation to the metal made-up belt by centralising device before entering roughing mill, guarantee that metal made-up belt center is corresponding with the roll middle part, thereby guarantee rolling quality.
There is following problem in disclosed roughing mill centralising device at present: the guide roller that a pair of centering in the existing centralising device is used drives by two motors, simultaneously automatic centering work, and the centering position is inaccurate, the centering weak effect; Guide roller running fix is located by groove, and precision is not high, rocks greatlyr, affects centering operation.
The utility model content
Technical problem to be solved in the utility model provides a kind of roughing mill centralising device, and to reach simultaneously automatic centering of guide roller operation, the centering position is purpose accurately.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of roughing mill centralising device, comprise motor, screw mandrel, base and guide roller, motor output end is connected with screw mandrel one end, and the guide roller in the metal tape both sides on the described base all is located on the same screw mandrel.
Described guide roller is by suitable guide pillars and bushes guide-localization, and guide pillars and bushes all is located on the base.
Described motor is hydraulic motor.
The utility model compared with prior art, have the following advantages: drive the simultaneously centering operation of two guide rollers of metal made-up belt both sides by single-motor, the centering position is accurate, improved rolling accuracy, also by guide pillars and bushes the guide roller mobile guide is located, guide-localization is more stable, further improves the centering effect.
Description of drawings
The below briefly explains the expressed content of each width of cloth accompanying drawing of this specification and the mark among the figure:
Fig. 1 is the utility model centralising device organigram.
Fig. 2 is the utility model centralising device and roughing mill import organigram.
Among the figure: 1. motor, 2. screw mandrel, 3. base, 4. guide roller, 5. guide pillar, 6. feed roller, 7. nip rolls, 8. press mechanism.
The specific embodiment
The below contrasts accompanying drawing, by the description to embodiment, the specific embodiment of the present utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of roughing mill centralising device comprises motor 1, screw mandrel 2, base 3 and guide roller 4, and screw mandrel 2 and guide roller 4 all are located on the base 3, is provided with the motor 1 that drives usefulness in a side of base, and preferred, motor is hydraulic motor.The clutch end of motor 1 is connected with screw mandrel 2 one ends, two guide rollers 4 in the metal tape both sides on the base 3 all are located on the same screw mandrel 2, by screw rod transmission, drive the simultaneously automatic centering of two guide rollers or outwards open action, it is rolling to make the metal made-up belt automatically enter the roughing mill middle part.
Preferably, the stability that moves in order to improve guide roller further improves the effect of centering, and guide roller 4 is by suitable guide pillar 5 and guide pin bushing guide-localization, and guide pillar 5 and guide pin bushing all are located on the base 3.
Further, when metal made-up belt tail end passes through feed roller 6 charging of roughing mill, easy perk damage equipment and harm safety of workers.For improving security, reduce the damage to equipment, be provided with nip rolls 7 on feed roller 6 tops, nip rolls 7 is by the distance between press mechanism 8 adjustings and the feed roller, and preferred, press mechanism 8 is suitable nut and screw rod, and is simple in structure.
The above has carried out exemplary description to the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that design of the present utility model and technical scheme carry out; or without improving design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
