Description
Technical field
The present invention relates to a kind of rectification roll device of cold-rolling mill, the novel rectification roll device that specifically uses on the band precise cold milling train.
Background technology
The rectification roll device that band precise cold milling train adopts at present extensively is a driven roll, and rotatablely moving of rectification roll is the frictional force drives that the tension force by band produces on rectification roll.Rectification roll not only is used to change the direction of motion of band when rolling, when precision rolling, also is used to measure the speed of service of band, the control cold-rolled process.When the especially accurate book band of precise cold milling train cold-rolling mill is rolling the total tension force of band thicker be with much smaller; But in order to guarantee the strip surface quality, the rectification roll diameter is often bigger, is with rolling being more or less the same with thick; It is serious so just to cause milling train when quickening or slow down, to skid between band and the rectification roll; Influence the band rate accuracy, thereby reduced the rolling accuracy of milling train, cause the strip quality instability, influence finished product strip surface quality.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thereby a kind of novel rectification roll device of band precise cold milling train is provided, at utmost utilize original rectification roll assembly, the appropriate design driving mechanism; Use is reliable, net synchronization capability is good, can effectively guarantee the rolled piece quality.
According to technical scheme provided by the invention, the novel rectification roll device of cold-rolling mill comprises photoelectric encoder, encoder support, rectification roll, shaft coupling, reductor and drive motors; The two ends spindle nose of said rectification roll is bearing on the clutch shaft bearing seat and second bearing block through rolling bearing; The clutch shaft bearing lid is installed on the outer face of clutch shaft bearing seat; Second bearing cap is installed on the outer face of second bearing block, and the two axial ends of rectification roll is equipped with the first axle head baffle plate and the second axle head baffle plate respectively; Said photoelectric encoder is installed in clutch shaft bearing through the encoder support and covers, and the axle head of photoelectric encoder connects with spindle nose on the first axle head baffle plate through the shaft coupling on the encoder; Said drive motors is connected on second bearing cap through reductor, and the spindle nose on the spindle nose of reductor and the second axle head baffle plate is linked by shaft coupling.
Said rectification roll is a solid or hollow steel roller, and the surface under the situation that guarantees rectification roll intensity and rigidity, reduces the quality of rectification roll, to reduce its rotary inertia through cure process as far as possible.
Said drive motors adopts direct current generator or alternating-current variable frequency motor, realizes direct current or frequency control, according to the size cases apolegamy reductor of cold rolling speed, if motor speed is suitable mutually with cold rolling speed, also can not adorn reductor.Said reductor is selected the RF helical speed reduction gear for use.
Compared with present technology the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure; Overcome the operation asynchrony phenomenon between band and the rectification roll, tested the speed accurately; Response speed is fast, highly sensitive; Can effectively guarantee rolling mill characteristic.
Description of drawings
Fig. 1 is the structural representation of novel rectification roll device.
