Definitions
- the invention relates to a media coupling, comprising coupling elements for coupling and / or uncoupling the media feed lines arranged on a roll stand with media connections of chocks of roller bearings that can be guided in roller stands, in particular for work or backup rollers.
- Coupling and uncoupling the media supply lines is particularly difficult with the oil flood bearings of roll stands, because the coupling connections of the bearing chocks are also on the drive side of the roll stands, which is difficult to access.
- the object is achieved in an inventive manner in all four chocks of the support rolls or the work rolls with a media coupling, comprising coupling elements for coupling and / or uncoupling the media feed lines arranged on a roll stand with media connections of chocks of roller bearings which can be guided in roll stands, in that the coupling elements the media inlets and outlets on the roll stand with media connections of the chocks are designed such that they can be coupled or uncoupled automatically in such a way that there is a media coupling free of the roll stand and firmly on the roll chock.
- the media coupling which is carried out automatically, creates a media coupling that is completely free of the stationary roll stand and is only firmly connected to the roll chock and can therefore participate in its movements.
- One embodiment of the invention provides that the media connections of the chocks for the uncoupled state are equipped with automatic means for oil-tight sealing.
- the design of the media connections according to the invention is further characterized in that the means for the automatic oil-tight closure are designed in the form of a spring-operated flap or a piston.
- the means for the automatic oil-tight closure are designed in the form of a spring-operated flap or a piston.
- all four chocks of the support rollers or the work rollers are each provided with an automated oil return flap or sealing piston and further media connections for oil supply, oil return, for hydrostatics, hydraulics, grease lubrication, pneumatics or the like are provided.
- the media coupling is expediently designed for the passage of relatively large amounts of oil with low return resistance.
- a return support which, integrated in the automatic process control, is equipped with a jet or impeller pump either with a drive that can be acted upon by the leading oil or with a drive that can be supported with electrical energy.
- the spring-actuated flap or spring-actuated piston has a sealing cone that can be closed against a seal.
- the oil return pipe can expediently also be provided with a radial shaft seal.
- the block of building blocks which can be guided in the vertical direction on a roll chock can be coupled with a coupling counterpart which can be arranged on the roll stand and which has an interchangeable plate which has an actuating element, in particular in the form of a hydraulic cylinder - and slidably cooperates to the coupling process.
- Fig. 1 in side view and partly in section, the media coupling with locking piston in the unlocked state on a roll stand.
- Fig. 2 in side view and partly in section, the unlocked media coupling with closure flap on a roll stand.
- Fig. 3 partly in section and partly in side view of the media coupling with the transfer coupling element in a coupled state.
- Fig. 4 also in a coupled state, the main oil return line and other media connections for oil flow, hydrostatics, hydraulics or the like.
- FIG 5 shows a drive arranged in the oil inlet for an impeller pump arranged in the oil return.
- the media coupling comprises coupling elements for coupling and / or uncoupling the media feed lines fixedly arranged on a roll stand 20 with media connections 24 (FIG. 4) of chocks 21 of roller bearings that can be guided in roller stands, in particular for work or backup rollers ,
- the coupling elements of the media supply and discharge lines 1 to 4 on the roll stand 20 are designed such that they can be coupled or uncoupled automatically to one another with media connections 5 of the roll chocks 21.
- the media connections of the chocks 21 are equipped with automatic means for oil-tight closing for the uncoupling state.
- these means can be in the form of a spring-actuated piston 12, as shown in section in FIG. 1 within the building block 5.
- All four chocks 21 of backup rolls or the work rolls are each provided with an automated oil return flap 17 or piston 12, provided only for unpressurized large oil return, all other supply lines are with standard quick-action couplings 24 for oil supply, for the hydrostatic, the Hydraulics, grease lubrication, pneumatics or the like.
- the coupling is advantageously designed for the passage of relatively large, unpressurized oil quantities with low return resistance.
- the spring-actuated flap 17 or the spring / pressure oil-actuated piston 12 expediently has a sealing cone 18, which can be closed against a radial shaft sealing ring 19 if necessary.
- the on the roller chock 21 in Fig. 1 in the vertical direction block 5 can be coupled with a mating to the roller stand 20 coupling counterpart 22, which has a removable plate 4, which can be pushed back and forth with an actuator in the form of a hydraulic cylinder 1 Coupling process interacts.
- the interchangeable plate 4 is designed and arranged for the coupling process with guide bores 31 such that it is pushed down by the bolts 3 from the cylinder 1, the other bolts 3 ′ (FIG. 4) of the interchangeable plate 4 in centering bores 11 of the building block 5 Bite in and center yourself at the same time.
- the interchangeable plate 4 is guided securely, docked to the building block 5 and finally clamped with the mandrel or clamping element 30 on the building block 5 and thus on the movable roller chock 21. (Fig. 3)
- the mandrel which is provided, for example, with a rotatable hammer head connection, is pressurized by hydraulic oil pressure and thus braced.
- the building block 5 is fastened to the roller chock 21 so that it can be screwed on and provided with a return flap 17 or piston 12 which can be spring-actuated by the oil return opening 6.
- the interchangeable plate 4 is equipped with centering bolts 3 'and the plate 29 on the roller chock 21 with corresponding centering bores 11, into which the centering bolts 3' engage during the coupling process. (Fig. 4)
- the media coupling shown in FIGS. 1 to 4 can have further coupling transfer elements 24 for media such as water, compressed air, lubricants etc.
- the interchangeable plate 4 can be clamped to the building block 5 using a clamping element 30 (FIG. 3) known per se.
- the media couplings for the roller chocks 21 with coupling counterparts 22 which can be automatically coupled to one another can be designed with means for locking the chocks 21 with the roller stand 20.
- the coupled or uncoupled position of the media coupling is preferably monitored by electrical signal transmission, and the signals are integrated into the automatic process.
- a return support is provided which, integrated into the automatic process, is equipped with a jet or impeller pump 28. This can either have a drive 27 which can be acted upon by the leading oil 25 or a drive 27 which can be supplied with electrical energy, as is shown schematically in FIG. 5.
- step 1 is acc. Fig. 1, the removable plate 4 held in a waiting position by the bolts 3.
- the cylinder 1 is in the retracted position.
- the roller chocks 21 can be changed.
- the oil return opening 6 is closed with a valve cone 7 of the interchangeable plate 4 as shown in FIG. 3, and the rest
- Transfer points for other media are also closed by appropriate standardized coupling designs, cf. Fig. 4, item 24.
- cylinder 1 is extended.
- the removable plate 4 is from the bolts
- Vane pump 30 Clamping element / mandrel
