Definitions

  • the invention relates to a straightening machine for rolled beams, in particular hyper-beams, in which at least one of the two straightening disks which bear against the beam flanges from the inside and are supported by a straightening shaft can be adjusted axially.
  • a straightening shaft for straightening machines of this type has become known from DE-35 22 976 A1.
  • This straightening machine is used to straighten rails.
  • hot-rolled double-T beams or hyper-beams to be straightened it should be noted that they have a constant height dimension depending on the series, whereas the flange thicknesses can vary.
  • the determination of the height H enables optimized connections (gusset plates) of the girders with different resistance moments in steel buildings.
  • the current straightening practice in a straightening machine downstream of the carrier line provides that the beams are moved into the straightening machine lying on the flanges and then run over the straightening disks with the web. This means that the flanges have to be plastically deformed during straightening and all the required straightening forces are passed through the web and the transition radius from the web to the flanges in the flanges. Since the flanges also begin to breathe due to the deformation of the web and exert an axial force - clamping the carrier - on the straightening discs, an axially stable construction is required.
  • the straightening disks are therefore fixed to a mounting bushing using a spacer bushing or spacer washers, corresponding to the dimensions of the chamber, and completely replaced if necessary.
  • This assembly bushing unit is placed directly on the straightening shaft and axially clamped there by means of a clamping nut or a clamping head. In the case of a changed chamber dimension due to different flange thicknesses, this is equivalent to a very time-consuming changeover time, since each chamber dimension deviation inevitably leads to a change in the assembly bushing unit.
  • the invention is therefore based on the object of providing a simple, maintenance-friendly possibility in a straightening machine of the type mentioned at the outset, which allows the outer or chamber dimensions of the straightening disks to be changed quickly.
  • a support ring for a plurality of hydraulic cylinders distributed over the circumference is arranged between the straightening disks, the actuating pistons of which are connected to a straightening disk.
  • the straightening disks of a straightening shaft is connected to the actuating piston, preferably via threaded bolts by means of a screw connection, this straightening disk can be axially adjusted when the actuating piston is subjected to the displacement pressure - approximately 100 bar - and thus adapt the chamber dimensions to changed flange thicknesses, whereby it goes without saying that an adjustment to a series with fundamentally different carrier dimensions is equally possible.
  • the second straightening disc can remain in its once defined position; nevertheless, both straightening disks could also be adjusted axially, for which purpose hydraulic cylinders could be arranged in the supporting ring from both end faces.
  • the hydraulic cylinders which are advantageously screwed into the nut and consequently designed as screw-in elements, and are therefore located in bores in the nut, can be screwed in as a complete structural unit and are accordingly completely interchangeable.
  • a preferred embodiment of the invention provides ring lines connecting the hydraulic cylinders to one another. This allows the actuating pistons to synchronize when the displacement pressure is applied to them.
  • the support ring has three ring lines, each of which is assigned a central media coupling in the form of a quick-connect plug-in coupling.
  • the actuating pistons could alternatively be designed with a spring return.
  • the clamp connection opens into a pressure chamber formed between each hydraulic cylinder and a sleeve surrounding the actuating piston.
  • the sleeve thus acted upon from the outside with a hydraulic pressure - approximately 500 bar - fixes the actuating piston in its position, so that the high straightening forces cannot bring about an undesirable change in position.
  • the support ring is advantageously arranged on a feather key and is braced from one side onto a threaded section of a mating ring which surrounds the straightening pin of the straightening shaft, it can on the one hand be quickly and easily installed and fixed; on the other hand, there is automatic positioning in such a way that the hydraulic cylinder of the support ring and the threaded bolts define the straightening disk, which is also guided on a feather key, that is to say they lie opposite one another.
  • an axial chamber bore in the support ring can be provided with a displacement sensor, to which a magnet is assigned in the straightening disk.
  • the chamber bore can be provided on the same pitch circle as the circumferentially distributed bores for the hydraulic cylinders in the end face of the support ring, which simplifies production, since all bores can be drilled or produced in one operation.
  • the straightening pin 4 of a lower straightening shaft 1 is shown in FIG. 1 of a straightening machine which has upper and lower straightening shafts 1 with straightening disks 2, 3 arranged thereon; the upper straightening disks 2a, 3a interacting with the lower straightening disks 2, 3 for straightening a hot-rolled hyper beam 5 are only indicated schematically.
  • a clamping head 6 known as such, with the aid of which a mounting bush 7 accommodating the straightening disks 2, 3 can be braced against the straightening pin 4.
  • the mounting bushing 7 is designed with a wedge guide 8 on which the right-hand alignment disk 3 in FIG. 1 can be adjusted outwards.
  • a displacement unit 18 For displacement there is a displacement unit 18 between the straightening discs 2, 3 (or 2a, 3a).
  • This consists of a support ring 20 provided with a groove 19 (cf. FIG. 3), which distributes a total of twelve chamber bores 21 over the circumference of its annular surface or 22, of which all but one chamber bore 22 accommodate a hydraulic cylinder 23 with an actuating piston 24 arranged therein (cf. FIGS. 1 and 2).
  • the support ring 20 is arranged on the key 13, which also guides the left-hand directional disk 2, of the mounting bush 7; its ring surface facing the right, movable directional disk 3 is formed with a recess 40 which is concentric with the shaft bore and into which a counter ring 41 provided with an internal thread can be screwed onto an external thread section 25 of the mounting bush 7.
  • axially adjustable straightening disk 3 26 threaded bolts 27 are arranged in axial bores, which are screwed into the actuating piston 24.
  • the actuating pistons 24 are enclosed over part of their length by a sleeve 28, and a pressure chamber 29 is formed between the hydraulic cylinder 23 and the sleeve 28 and is connected to a ring line 31 via a transverse bore 30 .
  • the support ring 20 also has two further ring lines 32, 33 which are designed as pressure medium connections in the form of transverse bores 34, 35 leading to the hydraulic cylinders 23 for an actuating and a return stroke.
  • the sleeve 28 is pressed against the actuating piston 24 by introducing hydraulic fluid supplied via the ring line 31 and the transverse bores 30 into the pressure chamber 29. It is understood that all pressure rooms are sealed.
  • a simple connection of the ring lines 31 to 33, which supply all the hydraulic cylinders 23 centrally, to a pressure medium source is achieved by a connection 37 provided in the support ring 20 for a plug-in coupling;
  • Each ring line 31, 32, 33 is assigned a plug-in coupling connection 37, which is connected to the respective ring line via a distributor bore 38.
  • a displacement sensor 39 is accommodated in the chamber bore 22 of the supporting ring 20, as indicated schematically in FIG. 3, to which a magnet (not shown) is assigned in the straightening disk 3.
