Definitions
- the invention relates to a roll stand, both ends eccentric bearing sleeves mounted in parallel in a gearbox housing for, in both of these, also double-ended, roller supporting shafts with the outside of the bearing flying onto these attachable Rolling disks and, arranged between the support shaft ends, by a peripheral recess of the eccentric bearing sleeve with a Drive-meshing, spur-toothed shaft sections.
- Roll stands of this type in which the rolling disks and rolling fittings due to the flying storage of the rolling disks using of eccentric bearing sleeves, the adjusting devices and the rolling fittings are very accessible, usually with rolling disks small diameter equipped at relatively high Speeds with low rolling forces corresponding to low spreads of the rolling stock.
- the roller supporting shafts are stored in thin-walled heavy-duty plain bearings.
- the small diameter of the Rolling disks also allow the use of rolling disks Hard materials or hard metals that are particularly dimensionally stable and high Have caliber tool life.
- a disadvantage of these roll stands is that compared to roll stands with roller support shafts mounted on both sides of the roller disks lower scaffold rigidity, which the possible uses of such Rolling stands for precision rolling are severely restricted.
- the invention has for its object the rigidity of Generic roll stand to increase so that the stands at Precision rollers can be used.
- one of the two eccentric bearing sleeves is arranged in a, one-armed lever swing arm, which around one that runs transversely to the longitudinal center axis of the roller supporting shaft Axis can be swiveled or tilted using an elastic, adjustable and lockable actuator is supported against the gear housing.
- This form of training of the rolling stand according to the invention allows the Setting a desired rigidity of the roll stand, the small adjustment stroke of the elastic actuator Adjustment kinematics of the eccentric bearing housing of the roller support shaft caused adjustment of the rolling disks not affected.
- the actuator can be a position and force-controllable piston-cylinder unit, in addition to the setting of the desired rigidity of the roll stand too Precise correction of the respective via known control devices Roll gap allowed between the rolling disks.
- the swivel or Tilt axis of the lever rocker can, as the invention further provides be arranged longitudinally adjustable and fixable in the direction of the longitudinal center axis of the roller support shaft. This adjustability of the Longitudinal center axis makes an exact adjustment of that of the two Roll discs formed rolling caliber possible on the center of the roll.
- the Lever rocker can also be longitudinally displaceable as one end in the gear housing clamped spring rod be formed.
- the Invention further provides the pan or tilt axis of the Lever rocker or the spring rod designed as an eccentric bearing be. This training also allows a prestressed elastic Support with center correction of the tilt axis of the spring bar.
- the two roller support shafts 1 and 2 each stored in eccentric bearing sleeves 3 and 4 and wear on their, facing away from the bearing, from the gearbox 5 protruding ends 1a and 2a, the rolling disks 6 and 7, respectively together, here form a double rolling caliber WK.
- the eccentric bearing sleeve 3 (Fig. 1) mounted directly in the gear housing 5 while the eccentric bearing sleeve 4 in two approaches 8a and 8b (Fig. 2) a rocker arm 8 stores, which is pivotable about a bearing pin 9, which in one Distance d from the end 1b of the supporting shaft facing away from the roller disc 6 1 is arranged in the gear housing 5.
- the swivel bearing the lever arm 8 on the bearing pin 9 is not shown Formed as an eccentric bearing.
- the two roller shafts 1 and 2 have spur gears between their ends 1a, 1b and 2a, 2b, respectively Shaft sections 1c and 2c, these mesh with each Drive pinions through circumferential recesses in the eccentric bearing sleeves 3, 4 reach through. That sits on these pinions one, not shown, on which, driven by a bevel gear 10 Drive axle 11 (Fig. 1), while the other, with this Pinion meshing pinion 12 (Fig. 2) in the bearings 13 and 14th is loosely stored in the gear housing 5.
- the radial employment of the Roller support shafts 1 and 2 are attached, here 4b the eccentric bearing sleeves 4, attacking actuators 15 causes.
- the lever arm 8 which comprises the eccentric bearing sleeve 4, is supported with its free end 8c against the piston rod 16a, in the Wall of the gear housing 5 inserted piston-cylinder unit 16.
- the lever arm 8 and with this the Eccentric bearing sleeve 4, the roller bearing shaft 1 and the roller 6 with the help of the eccentric adjustment of the Bearing pin 9 in the direction of the center axis of the roller supporting shaft 1 Move WK to adjust the roll gap.
- the desired Bracing the two rolling disks 6 and 7 against each other is thereby by the piston-cylinder unit 16 and the associated, position and force control devices, not shown.
- the eccentric bearing sleeve with corresponding lugs 18a and 18b 4 detecting spring rod 18 in the region of the roller disk 6 facing away End 1b of the roller support shaft is longitudinally displaceable in the gear housing 5 clamped.
- the corresponding displacement of this spring bar 18 together with the eccentric bearing sleeve 4 and the roller support shaft 1 in the direction of its longitudinal center axis becomes 4 by an eccentrically mounted in the gear housing 5 pin boss 18d of the spring rod 18 causes the free end 18c against the piston rod 16a of the piston-cylinder unit 16.
- the other features of this training correspond to those the training according to FIGS. 1 and 2.
