Definitions
- the lower roller is first moved to the center of the roller, optical detection devices possibly determining the position of the lower roller.
- the upper roller driven at creep speed against the lower roller is placed against the former, any inclined positions of the upper roller relative to the lower roller being detected by roller pressure differences on roller pressure load cells arranged on both sides of the upper roller.
- the position of the top roller is corrected in accordance with this display.
- the known method is unsuitable for the exact horizontal alignment because the position of the top roller is oriented to the position of the bottom roller and both may not be aligned horizontally if the bottom roller has not been positioned horizontally. A parallel roll nip is thereby obtained, which, however, can be inclined overall from the roll plane.
- DE 24 54 896 A1 discloses a method for setting a parallel, open roll gap, in which forces corresponding to the adjusting drive means are applied to both roll sides.
- the present invention is based on the object of a roll stand with roll adjustment devices for the top roller and roller adjustment devices for the bottom roller and displacement sensors for detecting the position of the roll adjustments of the top roller, the position data recorded being storable in the memory of a computer to be designed in such a way that an exact horizontal alignment of both horizontal rolls is possible with essentially available means and to find a corresponding method for carrying out this alignment and adjustment process.
- a roll stand designed in this way enables a simple and inexpensive exact horizontal alignment of the top roll on the stop surfaces of the roll stand provided for this purpose and, via the geometrically defined points and the known dimensions of the roll stand and of the rolls, allows an exact detection of the position of the top roll.
- the method according to the invention for aligning and adjusting the upper and lower horizontal roll to the center of the stand in a roll stand according to claim 1 is characterized by the method steps described in claim 2.
- the present invention makes it possible to automatically align and set up the horizontal rolls of a horizontal or universal roll stand in such a way that the position of the top roll can be precisely defined via mechanical conditions and via the fixed and known position of the top roller the bottom roller can also be aligned horizontally.
- 1 denotes the stand of a horizontal rolling stand, the top roller of which bears the position number 2a.
- the upper roller 2a is mounted in the chock 3, which in turn is guided in the stand 1 in the horizontal direction.
- the balancing cylinders 4 are used, of which at least two correspondingly trained ear-like projections 5 engage behind the chock.
- stop surfaces can be seen in the stand 1, which are arranged at a precisely defined distance from the horizontal rolling center plane 7 at a distance a.
- the connecting line between the stop faces 6 on both sides is exactly parallel to the rolling center plane 7.
- FIG. 1 also shows the adjustment spindle for one side of the upper roller 2, which is numbered 9.
- the adjusting spindle 9 is connected via a spherical bearing 10 to a hydraulic cylinder 11, which is cup-shaped and engages around the piston 12 formed on the extended adjusting spindle 9.
- the hydraulic cylinder 11 or its piston 12 can be pressurized on both sides.
- the distance of the stop surface 8 from the center 13 of the chock 3 is denoted by b; this distance is geometrically predetermined and known. Also known is the radius r of the top roller and thus the distance c in FIG. 1. This means that with a known distance a of the roller center plane to the stop surfaces 6 and with a known sum of the distances b and c in the abutting state of the contact surfaces 8 and 6 the position the top roller and its apex 14 and thus its distance (d) from the roller center plane 7 are exactly known. In addition, the exact horizontal position of the top roller is given solely by the geometric conditions when the stop surfaces 6 and 8 abut one another by the mechanical fixing of the stop surfaces 6.
- the chocks of the top roller with 3a and 3b and the chocks of the bottom roller with 3c and 3d are mechanically precisely machined on their undersides, the dimension e being known as the distance between the contact surfaces of the lower adjusting spindles 15 on the contact surfaces 16 of the chocks 3c, 3d. With the distance f, the radius of the lower roller 2b and thus the distance from the center of the chocks 3c, 3d to the apex 14b of the lower roller is known.
- the chock 3 in the stand 1 is raised until the stop surfaces 8 on the top of the ear-like projections 5 come to rest against the contact surfaces 6 on the stand 1.
- a computer (not shown), the exact position of the top roller 2 relative to the stand 1 or the abutment surfaces 6 and the distance d between the apex 14 of the top roller 2 and the center plane 7 of the roller are calculated from the difference between dimension a and the sum of dimensions b and c.
- the top roller 2 which is in an exactly horizontal position, is clamped against the balancing via the adjustment cylinders 11 of the adjustment spindles 9, and with the aid of the adjustment the top roller 2 is moved in parallel and in the direction of the center plane 7 of the roller.
- the top roller is stopped about 2 mm before the center of the roll.
- the lower roller 2b With the help of the lower setting 15, the lower roller 2b is now also moved in the direction of the center roll plane 7, the position of the apex 14b of the lower roller 2b being calculated from the dimensions e and f and ggis. the position of the adjusting spindle 15 is known. Since the known dimensions merely indicate the theoretical position of the apex 14b of the lower roller 2b, but do not take play and wear into account, it can be expected that the lower roller will not be stopped exactly in parallel and in the center plane 7 of the roller.
