Definitions
- the invention relates to a roll stand and a method for adjusting the roll stand for the rolling operation.
- Roll stands usually consist of two roll stands with an adjustable one
- roller adjustment and an auxiliary adjustment to achieve a constant pass line Due to the construction, the stand window constricts when the rolling force is applied. With different rolling forces, there are different games in the stand window between the roll stand and roll chocks.
- a universal roll stand is known from DE 21 44 511 B2, consisting of a closed frame for the vertical rolls and chocks for the horizontal rolls, which are supported on upper and lower cross members.
- the traverses are connected to one another by means of traction spindles which pass through the frame and are axially immovable and rotatably mounted in such a way that they - and thus the horizontal rollers - can be adjusted centrally to the rolling or fitting line.
- the frame sits directly on the base plate of the foundation.
- a rolling stand which consists of four column columns, which are firmly anchored with a base plate and in which axially non-displaceable, rotatably mounted traction screws are arranged, the upper and lower ends of which are provided with opposing threads, one of which take up the upper and lower crossbeam and are adjustable via the roller sets in opposite directions.
- the stand columns also serve as guides for roller chocks, and short-stroke proportion cylinders are arranged between the lower backup roller installation kit and the lower traverse to apply the rolling force.
- the document US 4 712 416 A discloses a six-high roll stand with a horizontal offset of the work rolls.
- the invention is based on the objects of creating a new design principle for roll stands which adjust themselves to a constant pass line again and again without other aids.
- the rolling stand consisting of four stand columns, which are firmly anchored with a base plate and in which axially non-displaceable, rotatably mounted traction spindles are arranged, the upper and lower ends of which are provided with opposing threads that receive an upper and lower crossbeam and over which the
- Roller sets are adjustable in opposite directions to one another, the stand columns simultaneously serving as guides for roller chocks and the accommodation of bending blocks, and a short-stroke adjusting cylinder arranged between the lower support roller installation set and the lower cross member for applying rolling force, with a separate arrangement of the tension spindles and the roller chocks in the Stand columns a separation of the power transmission to the rollers and the leadership of the roller chocks can be achieved.
- the object is achieved by a method for adjusting the rolling stand with the features of claim 5.
- the invention is based on the function of moving parts opposite one another evenly (or unevenly) towards or away from one another via a right and left thread.
- the function of transferring the rolling force is separated from the function "guiding the roll chocks", which means that disadvantages such as roll stand window narrowing no longer occur. This also has a significant influence on the tendency to "humming".
- the construction consists essentially of four welded stator columns 1, which take over the guiding of the roller chocks 2 and the accommodation of the tension spindles 3.
- the column columns 1 are cast with the foundation, ie the base plate 6, and fastened by means of anchor bolts.
- the design for the rigidity is based on the expected loads from the roller chocks 2.
- the traction screws 3 with their right and left thread are moved into position in the unloaded roll stand. Only then is the rolling force set via a short-stroke adjusting cylinder 7 and - as indicated - introduced into the tie rods in the operating state via the crossbeams.
- the design is based on the expected max. Rolling forces.
- the self-locking in rolling operation is guaranteed by the small pitch in the thread, whereby the position can also be secured by a brake in the adjusting drive.
- An additional small positioning cylinder (not shown) can be installed in the upper cross member 4 opposite the short stroke positioning cylinder 7 for smaller positioning forces.
- the traction spindles 3 are driven by four synchronized individual drives or also by a drive with mechanical synchronism.
- the upper and lower traverse 4 and 5 move towards or away from each other depending on the direction of rotation of the tension spindles.
- the AW always adjusts to the pass line for the same roll diameter (StW, ZW, AW).
