Description
The present invention relates to a kind of new Rolling machine method for controlling shape, particularly a kind of improvement of Japanese HC six Roller Rolling machine template control technologys.
Novel high-performance template control Rolling machine has been invented according to the new reason of strip Rolling machine Rolling Roller distortion Theory by HIT, is called for short HC Rolling machine.The The machine adopts the Shaft of the just curved of symmetric force or curved work Roller of Negative and the whole middle Inter Roller of Tone to control template to the position.When promptly bending Roller, upper and lower work Roller not Theory is the moving Side of operation Side or Pass, and its curved Roller power all equates.At present, Japanese HC Rolling machine occupies advanced international standard in template control, in like product, have typicalness.Though HC six Roller Rolling machine templates control Neng Li More is strong, this is meant that mainly control has the Neng Li More that carries Roller tape edge portion and intermediate openings number of degrees value strong, full plate is had on wide carry Roller seam opening degree control ability everywhere then a little less than.For example, guarantee to have carry Roller seam middle part and limit portion opening degree constant, have that to carry the opening degree that Roller stitches 1/4th places be very difficult and only change.Up to now, the curved Roller mode that adopt countries in the world all only limits to the curved Roller power of this kind symmetrical expression, and the curved Roller power of the asymmetric that does not have this law to propose.
Task of the present invention is exactly will overcome six Roller Rolling machines control on full plate is wide in the past the shortcoming of carrying a little less than Roller stitches opening degree Neng Li More is arranged, a kind of asymmetric force hydraulic bending work Roller of the The of use machine is provided, not only can keep former machine constant at the opening degree of middle part and limit portion, and can control a year Rolling effectively and stitch other regional opening degree, thereby improved the ability of six Roller Rolling machines in full plate wide region template control.
When task of the present invention is the whole curved Roller power of the: Zai Tone that finishes like this, on work the curved Roller power of the moving Side of Roller Pass and down the curved Roller power of work Roller operation Side equate, on work the curved Roller power of Roller operation Side and down the curved Roller power of the moving Side of work Roller Pass equate.The big I of these two groups curved Roller power is chosen so that solely upright Tone is whole, generally is different numerical value.The direction of two groups of curved Roller power also Ke Du Li Tone is whole, and same work Roller held with the curved Roller of just curved Roller power, and the other end is bent Roller with the curved Roller power of Negative.Do like this and guaranteed that curved Roller power is symmetrical to the influence of carrying Roller seam shape is arranged to the band center line.Japan HC six Roller Rolling machines are when Rolling system band, and the end of general middle up and down Inter Roller moves laterally to band limit portion position respectively.Therefore door Roller props up for the Bomb of work Roller that to honour the band center be asymmetric in, and the curved Roller power of the symmetry of its Roller that works up and down is inequality to the influence that the shape of carrying the Roller seam is arranged, thereby has influenced the glacing flatness of template.Because the curved Roller power of this law is asymmetric, size and Orientation can independently select Select, thus can obtain the curved Roller power of former symmetry institute can not obtainable a large amount of curved Roller curves or curved Roller effects.Suitably select these power of Select just can accomplish that year Roller stitches the middle part and limit portion opening degree is constant.And only change Qi Inter opening degree everywhere.Thereby improved the template control ability of HC six Roller Rolling machines on full plate is wide.For this reason, Shall does some little improvement to the curved Roller oil cylinder and the fuel system of former machine.
Below with reference to accompanying drawing further Details being in invention carefully describes.
Fig. 1 is the partial sectional view of the Side of 450mmHC Rolling machine work Roller to view and change Roller oil cylinder.
Fig. 2 is the schematic diagram of HC six Roller Rolling machine asymmetric force hydraulic bending work Roller.
With reference to Fig. 1, shown in oil cylinder be the oil cylinder after improving.The curved Roller oil cylinder of former HC six Roller Rolling machines is communicated with up and down, can't realize that asymmetric force bends Roller.For the curved Roller of asymmetric force that realizes that the present invention proposes.The oil cylinder that Shall will be communicated with originally is separated into two independently oil cylinders, makes it respectively by the hydraulic system fuel feeding, thereby reaches the purpose that produces different curved Roller power.The curved Roller oil cylinder (1) of operation Side, (2) Calipering are separated by original curved Roller oil cylinder curved Roller oil cylinder, and their other structure and former machine are just the same, all adopt ram cylinder, and straight Trail is identical for oil cylinder.The link stopper (3) that is contained in the piston rod head of curved Roller oil cylinder (2) inserts in the T-slot (5) of Rolling Roller Shaft bearing (4).Other each curved Roller oil cylinder all has same spline structure.Make each oil cylinder Ji can realize the just curved of work Roller, can realize that also Negative is curved.With reference to Fig. 2, the curved Roller oil cylinder that the moving Side of curved Roller oil cylinder (1), Pass of hydraulic system (not drawing among the figure) work Roller (6) under operation Side goes up work Roller (7) provides same pressure oil ， The to bend Roller power f

2Size and Orientation Ke Yi Du Li Tone Zheng ， The realized HC six Roller Rolling machine asymmetric force hydraulic bending work Roller.
Adopt the HC six Roller Rolling facility of asymmetric force hydraulic bending work Roller that following characteristics are arranged:
1) two groups of curved Roller power f
1, f
2' and f
1', f
2Can (Du Li Tone be whole in the big scope of opposite) Zhi Inter De More with the direction of arrow among Fig. 2 in the just curved Roller power (identical with the direction of arrow among Fig. 2) of maximum and the curved Roller power of maximum Negative.
2) go up in Inter Roller (8), down in Inter Roller (9) can be with Shaft to the whole position of Tone, And and be asymmetric to the Bomb supporting of work Roller.
Owing to adopt the HC six Roller Rolling facility of asymmetric force hydraulic bending work Roller that These characteristics is arranged, analyze and Try tests to study and draws according to reason Theory:
1) in certain scope, whole the difference of carrying Roller seam middle part (10) and limit portion (11) opening degree is arranged is △ h if need to adopt curved Roller Li Tone, then bends Roller power f for two groups

2, can accomplish have the difference △ h that carries Roller seam middle part (10) and limit portion (11) opening degree constant, only changing has the Roller of carrying seam middle part (10) and limit portion (11) Zhi Inter opening degree everywhere.
Theory is with the HC six Roller Rolling facility of the bright employing asymmetric force of Shi Practice Dou Certificate hydraulic bending work Roller have better full plate wide plate type control ability to reason, and easy to operate, quick.
