Definitions
- the present invention relates to a standless roll stand, with at least two work rolls, which are stored in roller bearings and each extend along a roller axis, the rollers define a roll gap and the roll axes define a roll plane, the roller plane contains both roller axes, the roller bearings connected to each other via two groups of connecting elements are, with the groups on each side of the roller plane are arranged, the groups in an adjustment direction an adjustment path length are adjustable, with at least one of the Groups under load using an adjustment drive in the direction of adjustment is adjustable over a load path length, the load path length is considerably smaller than the adjustment path length.
- Roll stands of this type are known. With the stand-less mill stands the prior art are the connecting elements by the Adjustment elements assigned to the roll stand over the entire length of the adjustment path adjustable. This adjustability is also necessary to carry out conversion work on the rolling stand, e.g. change the roller to be able to. In operation, on the other hand, only the Adjust the roll gap - load-free or under load - by a few millimeters to be able to.
- the object of the present invention is the same Performance increases the cost and weight of a roll stand reduce.
- the task is solved in that the groups regarding the Part of the adjustment path length exceeding the load path length has no drive are trained.
- the invention is based on the finding that the adjustment over the entire length of adjustment by Tool can be made, which can be attached to the roll stand.
- the adjustment tool is then only once for several roll stands needed so that the single roll stand due to the lack of a Actuator for the entire length of adjustment and lighter Group of e.g. five or ten roll stands with only one common Adjustment tool for the entire group of roll stands is cheaper than if every rolling stand in the group had one provided its own adjustment drive for the entire length of the adjustment path would.
- the other of the groups of connecting elements can be by means of a other actuators also over the load path length - load-free or adjustable under load.
- the roll stand is still easier and more affordable if the other of the groups is completely unpowered. Especially in this last one Fall is only one for setting the roll gap under load Group of fasteners adjusted while the other group remains undisguised.
- the adjustment drive for adjusting the connecting elements under Load can either be a hydraulic cylinder unit or an electric motor be trained. If the adjustment drive as an electric motor is formed, if necessary, via a single motor using gears - a group of fasteners each be adjusted.
- the present invention further includes an adjustment tool for Attach to a stand-free roll stand, using the adjustment tool for simultaneous adjustment of all connecting elements of the roll stand one driven adjusting element per connecting element has through which the connecting elements of the roll stand over their entire length of adjustment are adjustable.
- the adjustment tool has a particularly simple design, if the adjusting elements are rigidly coupled together and the Adjusting elements is assigned a common drive, which is preferably is designed as an electric motor.
- a stand-less combination rolling stand has Rolling billets and the like two rolls 1, which are extend along horizontal roller axes 2.
- the roller axes 2 run parallel to each other and thereby define a roll plane 3.
- the rollers 1 define one Roll gap 4.
- the rollers 1 are stored in roller bearings 5, which have two groups 6, 7 of connecting elements 8 are connected to one another. How can be seen, the groups 6, 7 on each side of the Roll plane 3 arranged.
- the connecting elements 8 are in the area the roller bearing 5 is provided with counter-rotating threaded spindles 9.
- the Connecting elements 8 and thus also the groups 6, 7 of connecting elements 8 are in an adjustment direction z over an adjustment path length from e.g. 40 cm adjustable by turning.
- the fasteners 8 are at their upper ends 10 with square profiles provided by means of a later to be described Adjusting tool are adjustable.
- the connecting elements 8 themselves but are non-powered.
- the one group 6 of connecting elements 8 is an adjustment drive 11 assigned.
- the Adjustment drive 11 from two hydraulic cylinder units 12, wherein each connecting element 8 of group 6 has its own hydraulic cylinder unit 12 is assigned.
- the adjustment could also be made done by electric motors. An adjustment by electric motors would be advantageous in that both connecting elements 8 of the Group 6 adjusted synchronously by a common electric motor could become.
- the other group is 7 of connecting elements 8 designed completely without drive. Setting the Roll gap 4 under load can inevitably only take place by that a group 6 of connecting elements 8 is adjusted, while the other group 7 of connecting elements 8 is undisguised remains. But it would also be possible to use the other group 7 of Connecting elements 8 with hydraulic or electromotive To provide actuators, so that in this case the other Group 7 would be adjustable under load over the load path length.
- the connecting elements 8 of one group 6 by a load path length of e.g. 10 mm adjustable. Due to the symmetrical arrangement of groups 6, 7 on the left and to the right of the nip 4 this can therefore be reduced by half 10 mm, i.e. 5 mm, can be adjusted. This is for the proper one Sufficient operation of the roll stand.
- the mill stand by adjusting the hydraulic cylinder units 12 in one Adjusted angular range ⁇ , which is an adjustment of the roll gap 4 causes.
- the fine adjustment of the roll gap 4 is therefore carried out after the one-sided adjustment principle of a swing arm.
- the nip 4 will thereby by the one-sided hydraulic adjustment of one group 6 changed while the other group 7 is tilted slightly.
- the size of the angle of attack ⁇ allows the adjustment in the specified Size range from 5 or 10 mm.
- the adjustment by the entire adjustment path length is carried out with the adjustment tool shown in FIGS. 4 and 5.
- the adjustment tool has four adjusting elements 13 with which it the square profiles at the upper ends 10 of the connecting elements 8 can be put on.
- the adjusting members 13 have worm gears 14, by means of which they on the common shaft 15 and the spur gear 16 is driven by an electric motor 17 become.
- the Adjustment elements 13 through the shaft 15 and the spur gear 16 rigidly coupled together.
- the adjustment elements are driven 13 through the common of all adjusting elements 13 Drive 17. This means that synchronous adjustment is mandatory the connecting elements 8.
- the adjustment tool is placed on the roll stand characterized in that the adjusting tool by means of a not shown Crane held on an eyelet 18 and lowered onto the roll stand becomes. An adjustment of the Adjusting tool is carried out when lowering onto the roll stand.
- the adjustment tool is placed on the roll stand regardless of the location of the roll stand.
- the roll stand can so either in the rolling mill or outside this rolling mill, e.g. in a conversion area.
- the adjustment tool can be made stationary be.
- the roll stand - e.g. by means of a crane - placed on the adjustment tool.
- the roll stand according to Embodiment also has two rollers 1 'with vertical Roll axes 2 '.
- the expansion, the storage, the adjustment (also under load) etc. are completely analog.
- Corresponding Elements relating to the rollers 1 'therefore have the same number on how the corresponding elements in the rollers 1.
- the reference numerals are only marked with a line to distinguish them.
- the only difference worth mentioning is that per group 6 ', 7' of connecting elements 8 'only one connecting element each 8 'is present.
