Definitions
- the invention relates to a roll stand for rolling wire, with a scaffold frame and at least one chock with a roller-side shaft bearing and a counter shaft bearing, in which a roller support shaft with a shaft axis is mounted, which protrudes beyond the roller-side shaft bearing, so that a roller disc can be applied to the roller support shaft, the roll stand a hydraulic cylinder unit with a hydraulic cylinder and a hydraulic piston having.
- Such roll stands have become known from JP-A-60 044 107 and US-A-4 413 494.
- the hydraulic cylinder units are used to apply one the closing force counteracting the rolling force to make changes to the previously set one To prevent roll gap as far as possible.
- the invention has for its object a generic roll stand to further develop that in a simple, reliable and inexpensive way an exact adjustment of the roller support shafts can be carried out relative to each other can.
- the hydraulic cylinder is connected to the scaffold frame, thereby from the scaffold frame and an upper cylinder part is formed, and the hydraulic piston is connected to the chock is, wherein the hydraulic cylinder with the hydraulic piston a hydraulic hydraulic cylinder unit forms with which the roller support shaft with respect to another in the roll stand mounted roller support shaft is adjustable in an adjustment direction.
- the hydraulic piston is detachably connected to the chock, it is a simple one Disassembly of the hydraulic cylinder unit and / or the chock possible.
- the detachable connection of the hydraulic piston to the chock is structurally particularly simple if the hydraulic piston at least has a fitting bore with a threaded bore of the chock aligns a fitting screw for the Fitting hole is screwed in, which protrudes above the hydraulic piston, and on the dowel screw protruding above the hydraulic piston End of a screw nut is unscrewed.
- the guide of the roller support shaft by the hydraulic piston is particularly accurate when the hydraulic piston is on the chock facing side of the hydraulic cylinder unit, preferably also on the side of the hydraulic cylinder unit facing away from the chock, in a piston bearing, especially a plain bearing, is led.
- a turning of the chock by a parallel to the direction of attack Axis is particularly safely avoided if the chock in the Area of the roller-side shaft bearing transverse to the shaft axis and is mounted free of play transversely to the direction of attack.
- the roll stand has a hydraulic cylinder unit with has a hydraulic cylinder and a hydraulic piston
- the Compensation hydraulic cylinder unit near the counter bearing is arranged and the hydraulic cylinder with the scaffold frame and the hydraulic piston is connected to the chock is open a particularly simple way of tilting the roller disc the roller shaft can be avoided.
- the cost of the roll stand can be reduced if the Compensation hydraulic cylinder unit smaller than the hydraulic hydraulic cylinder unit is trained.
- a roll stand for rolling wire has a frame 1, into which a one-piece chock 2 is installed.
- the chock 2 has a shaft bearing on the roller side 3 and a counter shaft bearing 4.
- a roller support shaft 5 is supported with a shaft axis 6.
- the Roller support shaft 5 protrudes beyond the roller-side shaft bearing 3, so that a roller washer 7 from the outside onto the roller support shaft 5 is applicable.
- the scaffold frame 1 has two further shaft bearings 8, in which a further roller support shaft 9 is mounted.
- the other too Roller support shaft 9 projects at least on one side over its shaft bearing 8 addition, so that a further roller disc 10 can be applied to it is.
- the roller disks 7, 10 together form a roll gap for a wire to be rolled.
- the roller supporting shaft 5 is in relation to the further roller supporting shaft 9 adjustable.
- the roll stand has a hydraulic hydraulic cylinder unit 11 with a hydraulic cylinder 12 and a hydraulic piston 13 on.
- the hydraulic cylinder 12 is with the scaffold frame 1 connected.
- the hydraulic cylinder 12 formed by the scaffold frame 1 and an upper cylinder part 1 '.
- the hydraulic piston 13 is connected to the chock 2. Consequently can by moving the hydraulic piston 13 within the hydraulic cylinder 12 along an adjustment direction 14 the roller support shaft 5 with respect to the further roller supporting shaft 9.
- the hydraulic jack unit 11 is both pressure and position control. Thus, not only due to the position control a predetermined roll gap can be approached exactly. Due to the pressure control, the spring deflection can also be compensated of the roll stand when the rolling forces are applied to the Wire can be compensated.
- the hydraulic piston 13 three fitting holes.
- the chock 2 accordingly has three Threaded holes.
- the fitting holes and the threaded holes are in pairs with each other.
- the fitting screws 15 protrude clearly the hydraulic piston 13 out.
- On the protruding ends of the Dowel screws are unscrewed 16 nuts. This is on simple manner of the hydraulic piston 13 releasably with the chock 2 connected.
- the hydraulic piston 13 with the Installation piece 2 connected via three dowel screws 15. But it could a different number of fitting screws 15 can also be used. Even a single fitting screw 15 can be sufficient. It is crucial that the hydraulic piston 13 is connected to the chock 2 in such a way that both compressive and tensile forces can be transferred to the chock 2 are.
- the scaffold frame 1 has slide bearings 17 in which the hydraulic piston 13 is performed.
- a plain bearing 17 can be seen on the the chock 2 facing side of the hydraulic jack unit 11 and a bearing 17 on that facing away from the chock 2 Side of the hydraulic cylinder unit 11 arranged.
- the starting hydraulic cylinder unit 11 is in the vicinity of the roller side Shaft bearing 3 arranged.
- the roll stand is now in the Principle already operational.
- the nip between the roller disks 7, 10 can, however, be adjusted better if the roll stand additionally a hydraulic cylinder unit 18 with a Hydraulic cylinder 19 and a hydraulic piston 20.
- the balancing hydraulic cylinder unit in this case is close to the Counter-shaft bearing 4 arranged.
- the hydraulic cylinder 19 Just like the hydraulic hydraulic cylinder unit 11 is here also the hydraulic cylinder 19 the scaffold frame 1 and the hydraulic piston 20 with the chock 2 connected. Because the balance hydraulic cylinder unit 18 is less Forces to apply as the hydraulic jack unit 11, the compensation hydraulic cylinder unit 18 can be made smaller be than the starting hydraulic cylinder unit 11. Otherwise Construction, fastening and mode of operation of the hydraulic cylinder unit 18 completely analogous to the hydraulic jack unit 11 his.
- the roller support shafts have 5, 9 between their shaft bearings 3, 4, 8 toothed drums 21.
- the Toothed drum 21 of the roller support shaft 3 meshes directly with a drive pinion 22.
- the drive pinion 22 further meshes with a - not self-propelled - intermediate pinion 23, which in turn meshes with the toothed drum 21 of the further roller support shaft 9.
- the further roll supporting shaft is 9 rigidly arranged in the framework 1. It is also sufficient, since the roller shaft 5 is adjustable and it only on the relative position of the roller support shafts 5, 9 arrives at each other. In principle, however, the further roller supporting shaft 9 could also be in one Chock be stored similar to chock 2. In this case the further roller supporting shaft 9 would of course also be adjustable. There would then be an almost completely symmetrical structure of the Rolling mill.
