Definitions

  • the invention relates to a straightening machine for rolled beams, in particular H-beams, in which at least one of the two abuts the support flanges from the inside, is aligned axially adjustable by a straightening shaft, the one Alignment disc is firmly connected to the alignment shaft via a mounting bush, while the other straightening disc is fixed in position according to its setting dimension an adjustable sliding bush on the mounting bush - on the if necessary, several (up to three) straightening disks can be arranged - sits.
  • a profile straightener of this type in which the outer or chamber dimensions of the Alignment disks can be changed by axially shifting one alignment disk through EP-B1 0 472 765.
  • the sliding straightening disc is there on a sleeve or displacement sleeve concentrically overlapping the mounting bush arranged.
  • the mounting bush or sleeve is connected to the Straightening shaft connected, and another wedge spring provides the connection between the Mounting bush and the outer sleeve or sliding bush.
  • the mounting bush or sleeve is axially fixed by a pressure sleeve having a pin end concentrically surrounds the straightening shaft.
  • this pressure sleeve rotatably a threaded sleeve with a thread formed on its outer surface arranged.
  • a ring screwed onto this external thread is with the sliding bush connected to a rotation relative to a straightener frame to prevent instead the rotational movement in an axial Convert sliding movement of the sliding sleeve as soon as the adjustment motor in Operation is set.
  • this alignment disc adjustment eccentrically more or less large Crowds on.
  • the invention has for its object a generic straightening machine without to create the disadvantages mentioned, in particular with a simple structure To enable both the axial adjustability and the assembly and disassembly.
  • Gag or thread gag This can come in from the outside radial bores of the two which are in alignment with one another Sockets are inserted or screwed. In this case, the entire Pull the unit off the straightening shaft journal and change the profile in the Rolling mill correspondingly prepared unit with set straightening discs change. So that when changing the external or chamber dimensions this can be set exactly, can be from the outside on the two straightening discs Measuring device are placed. This can be equipped so that when reached the desired dimension, a hydraulic valve is controlled, which the Movement process is interrupted because the pressure medium acting on the piston / cylinder unit is interrupted.
  • a preferred embodiment of the invention provides that the sliding bush via an end with its shaft journal end on the piston rod of the piston / cylinder unit specified clamping bush rotatably connected to the straightening shaft and is axially adjustable by the piston / cylinder unit.
  • the connection of the piston / cylinder unit, preferably arranged centrally in the directional shaft Clamping bushing producing the sliding bushing can be rotated with the straightening shaft advantageous due to a radially expandable and releasable friction element achieve that between the straightening shaft and the clamping bush on the Straightening shaft journal is arranged.
  • Such couplings are on the market available and consist of a hollow bushing, in the interior of which a conical Ring piston can be moved hydraulically.
  • one arranged on the shaft journal secures Bayonet ring the mounting bush in its set operating position, that of A counter means is associated with the shaft journal end.
  • the bayonet ring and that Countermeasures do more than just secure the position of the straightening shaft straightened disc unit, but the one arranged in front of the bayonet ring Locking means, preferably a screw nut, also absorbs axial forces, if these are effective on the machine-side straightening disc.
  • Axial forces in generally only act on the straightening disks from the outside during the Straightening process if such forces are caused by incorrect positioning of the straightening disc should appear from the outside, the screw nut in front of the bayonet ring.
  • a hydraulic nut with a mechanical lock nut is on a roller section Between a fixing ring and the bayonet ring, a hydraulic nut with a mechanical lock nut (ring). With this you can go far greater force than would be the case with a mechanical counter that Press the assembly bushing over the bayonet ring onto the straightening shaft. Subsequently the locking device or the screw nut takes over the securing of the position mounted mounting bush, the pressure of the hydraulic nut afterwards can be drained.
  • An advantageous variant of the invention provides that the adjustable Straightening washer on the sliding bushing temporarily securing a hydraulic unit is connected upstream.
  • the adjustment of the sliding straightening counter mechanical Accordingly, mother becomes hydraulic in the sense of a conceptual identity with the preloaded bayonet by the hydraulic unit, which is only required on the construction site sufficient prestressing (approx. 50 t) is achieved so that the lock nut can be screwed onto the sliding bush. After preloading the straightening disc unit this hydraulic part or the clamping unit is removed again, whereupon the mechanical nut takes over the securing of the clamped position.
  • the upper and lower straightening shafts 1 arranged thereon Alignment discs 2, 3, is in the semi-symmetrical representation according to FIG. 1 of the straightening pin 4 of a lower straightening shaft 1 is shown.
  • the for straightening a hot rolled H-beam 35 cooperating with the lower straightening discs 2, 3 upper directional discs 2a, 3a are only indicated schematically.
  • a mounting bush 6 is wedged over a feather key 5, on which the rear straightening disc 2 is fixed by means of a mechanical nut 7.
  • the front or in Fig. 1 right-hand target 3 is in the direction of the two arrows designed to be displaceable or adjustable so that the chamber dimension 8, i.e. to change the distance between the two inner surfaces of the H-beams 35, for example when rolling beams with a different flange thickness or one other web height.
  • a sliding bushing 9 carrying the alignment disk 3 on a wedge guide 10 of the Assembly socket 6 arranged.
  • the straightening disk 3 is supported against inserts 11, to which they move from one to the sliding bush 9 from its free end screwed mechanical nut 12 is clamped.
  • the sliding bush 9 is via a schematically indicated screw connection 13 with a clamping bush 14 connected, which is at its shaft end on the direction of the piston rod or a piston rod head 15 arranged centrally in the directional pin 4 Piston / cylinder unit 16 is supported and fixed on it with a lock nut 17.
  • the adjustable straightening disc 3 must be open the mounting bush 6 in the direction of the arrow pointing to the right in FIG. 1 on the Wedge guide 10 are moved. This requires after stopping the straightening machine Via the hydraulic connection 23, the expansion element 21 only with one Hydraulic unit, not shown, connected and the friction between the Clamping sleeve 14 and the directional pin 4 to be lifted. Then with Piston / cylinder unit 16 to be pressurized oil then adjusts the one with the Clamping bushing 14 screwed displacement bushing 9 and the one carried by it Straightener 3 in the desired, metrologically monitored new position.
  • the maximum adjustment range for The straightening disc 3 can also - provided that for certain applications should be necessary - in a simple manner by extending or from the outset shortened straightening pin 4 and clamping bush 14 vary.
  • FIG. 2 The disassembly of the straightening disk unit is shown in FIG. 2.
  • the piston / cylinder unit 18 thus fulfills two functions, namely the positioning of only the one Sliding sleeve 9 for chamber dimension adjustment and the other last described pulling the entire assembly from the straightening shaft 1.
  • Die Piston / cylinder unit 16 has two controlled by a proportional valve, the speeds assigned to each function.
  • the dot-dash line in FIG. 1 circled component is between the axially acting on the mounting bush 6 Bayonet ring 18 and a fixing ring 36, a hydraulic nut 29 is provided it allows the mounting bush 6 with greater force on the straightening shaft 1 and the Fixing pin 4, one with the lock nut 20 comparable lock nut 37 - as soon as the pressure of the hydraulic nut 29 is released has been - then the securing of the pushed-on mounting bush 6 takes over.
  • 3 is a hydraulic unit 30 arranged on the clamping bush 14 shown, but only on the site for pre-assembly of the straightening disc unit is required to force a larger to bias the straightening discs 2, 3 to be able to muster.
  • this Hydraulic unit 30 then removed again and as in FIGS. 1 and 2 shown, the mechanical lock nut 12 takes over the fixing of the Supplements 11 set clamped position of the straightening discs.
