Definitions
- the invention relates to a calender with a Stand and a roll stack, the lower roll one Deflection roll is, with a jacket over one acting in the direction of the center plane of the roll stack Deflection adjustment device against one Rotation-secured carrier is supported on both Ends in adjustable by load devices Bearing blocks is held.
- the multi-roll stack has a vertical center plane.
- the bearing blocks for the as deflection adjustment rollers trained bottom rollers are in a linear guide held and guided on the stand.
- Below the bearing blocks each have a loading device in the form of a hydraulic cylinder that applies the contact pressure the lower roller against the in levers above the lower roller stored center rolls of the calender and finally generated against the stationary top roller. Frictional forces occur with this linear guide on, which falsify the stress forces and in particular to uneven loads on both roller ends to lead.
- the invention is based, to a large extent the task smooth movement of the lower roller bearing blocks to enable.
- each bearing block can be swiveled with a single one on the stand mounted pivot lever is connected and that the Direction of action of the deflection adjusting device an adjustment of the bearing blocks with the aid of a correction device, the one along a guideway has displaceable guide element, essentially is maintained.
- the correction device intended.
- the lower roller moves the guide element along the guideway and acts on the Deflection adjuster so that their Maintains direction of action.
- the guideway is preferably attached to the stand and the guide element is movable with the bearing block.
- the placement of the guideway on the stand makes no difficulties in practice. Through the Movement of the bearing block will trigger the correction.
- the carrier as is usual, at its ends is firmly connected to the bearing block, it is recommended yourself that the bearing block is articulated with the swivel lever is connected and carries the guide element.
- the bearing block is firmly connected to the pivot lever is that the carrier in the bearing block by at least one limited angle is rotatable and that a the guide element supporting correction lever with the support firmly connected is. Accordingly, the angular position of the Carrier responsible for the direction of action of the deflection adjustment device is responsible from the correction lever changed directly.
- the guideway advantageously has a two-sided limitation is formed as a groove or slot. This results in safe guidance.
- the guideway is formed by a contact surface against which Guide element is held by pressure means. This leads to a play-free adjustment.
- This preferably forms the pressure means are that the forces of the loading device are outside the center plane of the lower roller on the bearing blocks attack. A small lateral offset of the load forces leads to a secure installation of the guide element on the guideway.
- the lower part of a roll stack 1 is the lower part of a roll stack 1 illustrated.
- a lower roller 2 and is shown a part of the next middle roll 3.
- the lower roll 2 is designed as a deflection adjustment roller; it therefore has a jacket 4, which has an indicated Deflection adjustment device 5 on one Support 6 is supported. This is firmly in a bearing block 7 clamped and therefore secured against rotation.
- the bearing block 7 is one by the piston 8 Loading device 9 resilient from below, so that the Rolling the roll stack 1 by lifting the bearing block 7 moved together and then loaded accordingly can be.
- the deflection adjustment device 5 is only schematically illustrated. It exists in the present Embodiment from a series of support elements 10, which is arranged radially displaceably on the carrier 6 are, which determines the direction of action, the coincide with the center plane E of the roll stack should. But there are other types of deflection adjustment into consideration, for example a roller with pressure spaces between the carrier and the jacket, which are delimited by longitudinal and transverse seals.
- a pivot lever 11 is fixedly attached to the stand 12 Swivel axis 13 swivel. It carries on the other End of the bearing block 7 by means of a joint 14.
- a correction device 15 is a straight on the stand 12
- Guideway 16 is provided, the middle plane E of the roll stack 1 has a slight inclination.
- a guide element 17 in the Slidable form of a roller on the bearing block 7th is arranged.
- a secure pressure of the roller 17 on the guideway 16 is effected in that the Load force F2 by the distance e from the central plane E of the roll stack 1, in which the reaction force F1 rules, is offset.
- the resulting Torque presses the guide element 17 against the guideway 16.
- FIG. 3 are for corresponding Parts with reference numbers increased by 200 compared to FIG. 1 used.
- the main differences are:
- the bearing block 207 is fixedly attached to the pivot lever 211.
- the end of the carrier 206 is twist tested with one Correction lever 218 connected to the other end the guide member 217 in the form of a roller wearing. This engages in a slot-shaped guideway 216 a.
- a pivoting of the pivot lever 211 is shifted downward also the guide element 217 down.
- the carrier 206 is countered pivoted clockwise so that in the overlay the deflection adjuster 205 their Direction of action in the center plane E of the roll stack maintains.
- the angle between the guideway and the median plane of the roll stack 2 depends on the local Circumstances. In particular, small wraps come from about 10 or 15 °, in some cases also larger angles from 20 to 30 °.
