Definitions

  • the invention relates to a straightening machine for rolled beams, especially hyper-beams, in which at least one of the two is the Carrier flanges from the inside, from a straightening shaft worn alignment discs is axially adjustable.
  • a straightening shaft for straightening machines of this type is provided by DE-35 22 976 A1 became known. With this straightener, rails directed. Above all, however, for hot-rolled double-T beams to be straightened or hyper beams, it should be noted that these are series-dependent have constant height, while the Flange thicknesses can vary.
  • the determination of the height H enables Optimized connections (gusset plates) in steel buildings Beams with different moments of resistance. So that hyper beams roll with different flange thicknesses, it is known the rolling disks of the roll in the rolling stands in carrier lines to adjust that on the one hand the constant height of the wearer is observed, on the other hand nonetheless different flange thicknesses can be rolled.
  • the adjustment time on the roll stand is here about 30 seconds.
  • the current straightening practice at one of the carrier lines Straightening machine provides that the carrier on the flanges driven horizontally into the straightening machine and then with the bridge run over the straightening discs. That means the flanges must be plastically deformed during straightening and all required straightening forces via the web and the transition radius from Bridge to the flanges to be directed into the flanges. Because through the Deformation of the web also causes the flanges to start breathing and one axial force - pinching the beam - on the straightening discs an axially stable construction is required. The Straightening disks are therefore over a spacer bush or spacers, according to the dimensions of the chamber, firmly on a mounting bush assembled and completely replaced if necessary.
  • This assembly socket unit is placed directly on the straightening shaft and axially there clamped by means of a clamping nut or a clamping head.
  • the invention is therefore based on the object in a straightening machine a simple, easy to maintain of the type mentioned Possibility to create that allows the outer or chamber dimensions of the straightening discs to change quickly.
  • a preferred embodiment of the invention sees the hydraulic cylinders interconnecting ring lines. This allows synchronism of the actuating pistons if these with the displacement pressure be charged.
  • One embodiment provides that the terminal connection in between each hydraulic cylinder and one surrounding the actuating piston Sleeve trained pressure chamber opens.
  • the outside with one hydraulic pressure - about 500 bar - loaded sleeve fixed the adjusting piston in its position so that the high straightening forces cannot cause an undesirable change in position.
  • the support ring is advantageously arranged on a feather key and by one from one side onto a threaded section of one Screwed the alignment pin of the assembly sleeve surrounding the alignment shaft Counter ring is clamped, it can be quickly on the one hand and easy to assemble and fix; on the other hand there is automatic positioning in such a way that the hydraulic cylinder of the support ring and the threaded bolts also on a directional washer, which means that it is aligned opposite.
  • an axial chamber bore of the support ring with a displacement sensor be assigned a magnet in the alignment disc In order to enable the position of the straightening discs to be checked provide an axial chamber bore of the support ring with a displacement sensor be assigned a magnet in the alignment disc.
  • the chamber bore can be distributed on the same pitch circle as the circumference bores arranged in the end face of the support ring for the hydraulic cylinders provide, which simplifies production, because all holes can be drilled or produce.
  • FIG. 1 From a straightener, the upper and lower straightening shafts 1 with Alignment disks 2, 3 arranged thereon, in FIG Straightening pin 4 of a lower straightening shaft 1 shown; those for judging a hot-rolled hyper beam 5 with the lower alignment discs 2, 3 interacting upper alignment discs 2a, 3a are only schematic indicated.
  • the mounting bush 7 is with a Wedge guide 8 formed on which the right in Figure 1 Alignment disc 3 can be adjusted outwards.
  • a displacement unit 18 For shifting there is between the straightening discs 2, 3 (or 2a, 3a) a displacement unit 18. This consists of a with a Groove 19 provided support ring 20 (see FIG. 3) on the circumference a total of twelve chamber bores 21 are distributed over its circular surface or 22, of which all but one chamber bore 22 another a hydraulic cylinder 23 with one arranged therein Take up the actuating piston 24 (cf. FIGS. 1 and 2).
  • the support ring 20 is on the key 13 also leading the left-hand alignment disk 2 the mounting bush 7 arranged; its the right, agile Direction plate 3 facing ring surface is with a shaft bore concentric recess 40 is formed, in which one with a Internally threaded counter ring 41 on an externally threaded portion 25 screw the mounting bush 7.
  • axially too adjusting washer 3 are 26 threaded bolts in axial bores 27 arranged, which are screwed into the actuating piston 24.
  • FIG. 2 As can be seen from the enlarged illustration according to FIG. 2, the actuating pistons 24 over a partial length of a sleeve 28 enclosed, and between the hydraulic cylinder 23 and the sleeve 28, a pressure chamber 29 is formed, which has a transverse bore 30 is connected to a ring line 31.
  • the support ring 20 has still two further ring lines 32, 33, which as to the hydraulic cylinders 23 leading pressure medium connections in the form of cross holes 34, 35 are formed for an actuating and a return stroke.
  • FIG. 2 (or FIG.
  • the left ring line 33 supplies via the transverse bores 34 on the piston surface side pressure chambers 36a and Ring line 32 via the cross bores 35 on the ring surface side Pressure spaces 36b of the hydraulic cylinder 23, which means that at Acting on the piston surface-side pressure spaces 36a an adjustment movement initiated to the right and the target 3 its feather key guide 8 is moved away from the straightening disk 2; of the Return stroke or moving the straightening disks 2, 3 together by introducing hydraulic fluid into the ring surface Pressure chambers 36b, whereupon the actuating piston 24 and thus move the straightening disc 3 to the left.
  • a displacement sensor 39 is accommodated in the chamber bore 22 of the support ring 20, as indicated schematically in Figure 3, that in the straightening disc 3 a magnet, not shown, is assigned.
