The present invention relates to rolling unit, this rolling unit has two roller bases of settling continuously at least in order to rolled steel bar or wire rod, wherein, distance between axles is shortened between the distance between axles between the roll of a roller base and the roll of another roller base, makes the guiding device that has saved between the roller base.
Rolling mill is a known technology, wherein has many roller bases to arrange continuously along a mill train, and product has passed through just to be rolled predetermined size after these roller bases.Each roller base all is provided with two rolls that rotatably are located in the roll stand frame, and product is then by process in the formed roll gauge of the groove in the roll (pass) (roll pass).The roughing of rolling mill and in roll the stage, the order of mill train (pass) can be " ellipse-circle ", wherein oval and circular roll gauge (pass) alternately setting successively.Perhaps the order of this mill train also can be " rhomboid-square ", and wherein rhomboid and square roll gauge (pass) are arranged alternately successively.But, in the finish rolling operation of rolling mill, usually will be with " ellipse-circle " mill train order from milling train, to send circular rolled products.
In " ellipse-circle " mill train order, can be able to accurately rolling so that make product can be sent to circular mill train with suitable direction thereby be provided with a roll-type guiding device at the entrance side of each circular mill train.In " rhomboid-square " mill train order, also be provided with similar guiding device so that dwindling of area reaches optimum state at the entrance side of each mill train.
In above-mentioned rolling mill, to use inevitably a roll gap adjustment device with regulate between the roll the gap in other words roller between roll gap (parting) so that regulate sectional dimension through the product between the roll.This roll gap adjustment device designs to such an extent that a roll can be moved closely a bit or far away from getting with another roll, and described another root roll then is fixed on the preposition.
When the roll gap between the adjusting roll, corresponding adjusting also must be done in the position that is arranged on the corresponding roll-type guiding device in the rolling unit, thereby makes valuable timeization in adjusting work.In addition, slip up to some extent and will produce defective, so just must often safeguard check on the roller guide surface whether scar and rolling condition thereof or the like are arranged pilot bearing because if product is directed the guiding of device.It should be appreciated that, be arranged on roll-type guiding device between the roller base make steel rolling equipment structure complicated and improved the manufacturing cost of device.
In this rolling mill, owing to be positioned at the entrance and exit side in order to the roller frame column of supporting roll gap governor motion, the distance between upstream roll seat and the downstream roller base has been strengthened owing to the existence of column.In addition, the roll-type guiding device that is arranged between the roller base also takes up room, and consequently the total length of rolling unit increases, and this is disadvantageous.
The present invention is intended to by significantly reducing distance between the steel rolling equipment roller base to avoid producing or alleviating at least above-mentioned variety of problems.
Another object of the present invention is the use of the guiding device between the cancellation roller base, thereby simplification is regulated the task of milling train to make it to adapt to the rolling of different big miscellaneous goods widely.
In order to overcome above-mentioned shortcoming and successfully to realize purpose of the present invention, rolling unit of the present invention is made up of two roller bases, these two roller bases are arranged to such an extent that make the rotating shaft of the roll of a roller base form the angles of one 90 degree with respect to the rotating shaft of the roll of another roller base, and the distance between axles between the roll of last roller base and the back roller base roll is not more than 1.2 times of diameter of these rolls.
Because the distance between axles between the roll of the roll of a roller base and another roller base of being arranged in order is not more than 1.2 times of diameter of these rolls, does not need to seek help from and is using guiding device also can prevent the distortion of product effectively between the roller base in the rolling mill practice process.Consequently, the master-plan of rolling unit is greatly simplified, and the investment of the means of production can reduce.In addition, can eliminate, also can avoid complicated inspection and maintenance operation guiding owing to guiding device is regulated the defective situation of the improper product that causes.Because the size of rolling unit can reduce, the entire length of rolling unit can correspondingly reduce, and the utilization rate of factory building can improve effectively.

Be described below in conjunction with the preferred embodiment of accompanying drawing rolling unit of the present invention.Should be noted that: in the preferred embodiment of being about to below describe, rolling unit 10 is to be used as finishing mill that finishing rolls in steel rolling equipment shown in Figure 12.But this rolling unit 10 also can be used for the interstage of the operation of rolling.Each rolling unit 10 has continuously arranged three roller bases 12,14,16, and its roll 13,15,17 is arranged to such an extent that make the downstream roll to the rotating shaft of (15 or 17) and adjacent upstream roll 90 degree (shown in Fig. 2 and 3) that differ to (13 or 15).In this embodiment, the roll 13 that is arranged in first roller base 12 is to be positioned at upstream position and the roll 17 that is arranged at the 3rd roller base 16 is to be positioned at downstream position with respect to the direction of rolled products 20, and their axle all is horizontally disposed.The roll 15 that is arranged on second roller base 14 between first roller base and the 3rd roller base 12 and 16, their axle, promptly roll 15 the axle be vertically disposed (as shown in Figure 7). Roll 13,15,17 in these roller bases 12,14,16 has been formed rolling unit 10, and they are driven by a drive motor 18 by a decelerator 19.
The distance between axles P of the roll 13 of first roller base 12 and the roll 15 of second roller base 14 is not more than 1.2 times of diameter R of roll 13 (15,17).Product 20 can accurately be directed in the roll gauge (pass) (roll pass) of roller base 14 and be gone, therefore, this is to realize by the distance between axles P that shortens between adjacent rollers 13 and the roll 15, does not adopt any guide means guide product between two roller bases 12,14.If the mechanism that the back will be narrated is used to regulate relative roll in roller base 12,14 or 16 to 13,15 or 17 roll gap (parting), the distance between axles between roll 13 and the roll 15 still can remain within the above-mentioned R1.2 that the is not more than roller diameter scope doubly.
Fig. 1 shows first roller base 12 of rolling unit 10 and the horizontal cross of second roller base 14.Because the structure of first roller base 12 and the 2nd, the 3rd roller base 14,16 structure is essentially identical, it is their arrangement difference, the rotating shaft that is roll 15 is with respect to the angle of roll to 13 and 17 axle deflection 1 degree, therefore only the structure of first roller base 12 is described below, the description of second and third roller base 14,16 is omitted.In the picture and text, the every parts with first roller base 12 of the parts of second and third roller base 14,16 are corresponding all uses identical numbering to represent.
On every roll stand frame 24, all be formed with a pair of perforate 24a.This roll stand frame places on the seat board 22 of rolling unit 10 (as shown in Figure 2).The position of perforate 24a near the downstream of roll stand frame 24 the upper and lower side who is used for the mill train line of conveying products 20 (pass line) PL.As shown in Figure 4, perforate 24a is vertical with mill train line PL.As shown in Figure 1, a pair of eccentric part 26 be can be rotated to support among the perforate 24a respectively.Being formed with an eccentric orfice 26a in each eccentric part 26 makes the center line of this eccentric orfice 26a and the center line of corresponding perforate 24a be offset to some extent.A pair roller axle 28 penetrates by axle 30 and be can be rotated to support among these eccentric orfices 26a.Roll is arranged on these roll mandrels 28 13 and rotates with axle.As shown in Figure 9, when each roll mandrel 28 all is provided with proper roll mandrel 28 and penetrates the eccentric orfice 26a of eccentric part 26, its axis C
1Axis C with respect to corresponding eccentric part 26
2Lateral shift is opened.And make the axis C of roll mandrel 28
1Can be clockwise or be rotated counterclockwise eccentric part 26 and moved with the mechanism that will be narrated below one.
The a pair of regulating shaft 32 that intersects with roll mandrel 28 can be rotated to support on the upstream portion of roll stand frame 24 to intersect with eccentric part 26.Worm screw 34 is arranged on each regulating shaft 32 with this rotation on the position of intersecting with corresponding eccentric part 26.The band toothed portion 26b that each worm screw 34 is designed on the circumference with corresponding eccentric part 26 is meshed.Two worm screws 34 that are arranged on each regulating shaft 32 are that two of being oppositely arranged are arranged on the same axle 28, then are arranged on the same side with eccentric part 26 engaged worm 34.One gear 36 is set with rotation therewith in the end of each regulating shaft 32.Be arranged on the corresponding regulating shaft 32 gear 36 by an appropriate driving device for example a motor adjusting gear 38 is done clockwise or rotation counterclockwise and being rotated in same direction, thereby corresponding eccentric part 26 is rotated by corresponding worm screw 34.Like this, can be changed to regulate the roll gap between phase breaker roll 13 (referring to Fig. 8,10) by the distance between axles between the roll mandrel 28 of a pair of eccentric part 26 supportings.
As mentioned above, in first roller base 12 with the roller gap governor motion that utilizes eccentric part 26, the downstream wall of roll stand frame 24 (be roll mandrel 28 to a side of biasing) is extremely thin (as shown in Figure 4).Similarly, as shown in Figure 1, in second roller base 14, roll mandrel 28 is arranged in the roll stand frame 24 with biasing upstream, thereby makes the upstream wall of roll stand frame 24 become very thin. First roller base 12 and 14 settings adjacent one another are of second roller base and make they corresponding roll stand frame 24 the thin-walled side toward each other, thereby 1.2 times of the diameter that distance between axles P between the roll 15 of the roll 13 of first roller base 12 and second roller base 14 can be reduced to be no more than roll 13 (15).Second roller base 14 and the 3rd roller base 16 arrange make that side of the roll stand frame 24 in second roller base 14 that the roller gap governor motion is set can be relative with the 3rd roller base 16 so that the distance between axles between roll 15 and the roll 17 greater than 1.2 times of the diameter R of roll 13 but be not more than 2R.
When operation, in the upstream roll line of the steel rolling facility shown in Figure 12, be sent to first roller base 12 of rolling unit shown in Figure 2 10 through rolling product 20, and through the mill train between the phase breaker roll 13 of first roller base 12 to reach predetermined rolling decrement.Then, be sent in the roll 15 formed mill traines of second roller base 14 through this product 20 after rolling.Because first roller base 12 and second roller base 14 are arranged to such an extent that the distance between axles P between roll 13 and the roll 15 is not more than 1.2 times of diameter of roll 13, product 20 can accurately be sent to the mill train of second roller base 14 and need not to use guiding device between the sort of roller base that uses in the prior art.Roll 13 in first roller base 12 is used as the guiding device of direct product 20 to second roller bases 14 simultaneously, so can prevent effectively that product 20 is twisted.In addition, because the very little mill train of rolling decrement of a kind of being called " finishing mill train " is arranged in last one mill train of finish rolling, therefore the distortion of product 20 can remain in the range of tolerable variance, even the distance between axles between the roll 17 in the roll 15 of second roller base 14 and the 3rd roller base 16 is greater than 1.2 times of roller diameters but also be like this when being not more than 2 times.
When wanting rolling product to be the minor diameter product, the gap between the phase breaker roll 13 in first roller base 12 is adjusted on the roll gap of being scheduled to (as shown in Figure 8), and roll 13 is with opposite directions rotation, wherein the axis C of roll mandrel 28
1Axis C with eccentric part 26
2Between present as shown in Figure 9 relation.Be sent between the roll 13 of first roller base 12 product sends into then in second roller base 14 just through a predetermined rolling decrement as fruit product 20.
When since order goods to change will rolling diameter be bigger in rolling unit of the present invention product the time, adjusting gear 38 by a drive unit in predetermined direction rotation so that regulating shaft 38 rotate in same direction.Because be arranged on each regulating shaft 32 worm screw 34 be arranged on or bottom roll axle 28 on the band toothed portion 26b of corresponding eccentric part 26 be meshed, eccentric part 26 can rotate among the perforate 24a in roll stand frame 24 when corresponding regulating shaft 32 rotations in a predetermined direction.Last eccentric part 26 and the 26 direction rotations opposite each other of following eccentric part are to change the axis C of the roll mandrel 28 that is supported by eccentric part 26
1Between distance as shown in figure 11.The roll gap that is arranged on like this between the phase breaker roll 13 on the roll mandrel 28 is increased (as shown in figure 10).When the roll gap between the roll 13 reached predetermined degree with the diameter of product 20 is different, the rotation of adjusting gear 38 just was stopped to finish roll gap and regulates.
The arrangement that should be understood that, the roll of corresponding roller base in the rolling unit can change, and promptly can take the arrangement different with above-described embodiment.For example the axle of the roll 13 of first roller base 12 and the roll 17 in the 3rd roller base 16 spool also can be vertical, the axle of the roll 15 of second roller base 14, it also can be level, in addition, in above-mentioned preferred embodiment, rolling unit of the present invention is made up of three roller bases, but this rolling unit also can be only with two roller bases.In addition, the steel rolling seat in the rolling unit also can be respectively each is self-driven by CD-ROM drive motor independently.
Obviously; those skilled in the art that; under the situation that does not break away from the present invention's spirit essence or scope; can implement the present invention with other form fully; therefore the foregoing description usefulness of explanation as an example only; the present invention is not limited to the foregoing description, but all these change within the protection domain that all still falls into the claims elaboration.
