Definitions

  • the invention relates to a straightening machine, in particular for straightening metal sheets and belts, with offset top and bottom straightening rollers, which are supported along their length by means of cross beams in turn, in roller mills arranged support rollers are supported, at least the upper crossbar for positioning the straightening rollers can be adjusted by means of adjusting cylinders, and compensation cylinders arranged between the roller mill and the crossbar.
  • Straightening machines are known, such as the type mentioned at the beginning according to EP-A-0 274 722, in which the support rollers can be preset in this way, that taking into account the deflection of the crossbeams under the straightening force the straightening roll deflection is compensated and thus the straightening rolls when Straighten are straight.
  • the transverse plane of the straightening rollers is divided and connected to one another in this way by articulated connections are connected that the cassette parts together with the groups of them carried Support rollers for the straightening rollers are slightly V-shaped under idling conditions can be.
  • the crossheads bend so far that the preset V-shape is canceled, the groups of support rollers are axially aligned and analogously the straightening rollers are straight, which compensates for the Deflection of the crossheads equals.
  • the crossheads - at least the top one Crosshead - are here as a whole about two pairs of themselves Adjusting devices supporting machine stands in the feed direction of the Alignment can be adjusted obliquely, so that the immersion depth of the displaced Straightening rollers for overstretching distribution from the infeed side of the straightening material to Let the discharge side decrease.
  • a different immersion depth staggered lower and upper straightening rollers are used to adapt to the when the leveling material enters and leaves the leveling machine different column expansions.
  • the straightening rollers must already be on the under idle conditions also create V-shaped groups of support rollers, which means that they must be pre-bent in a V-shape by forces acting on their ends. Since the extent of the straightening roll pre-bending due to the strong kink position of the Groups of support rollers must be considerable, the straightening rollers - until they are under the straightening force is straight - considerably stressed on bending. Finally presents itself as a problem that despite the tilting yoke the upper Center the roller mill with the lower roller mill so that one Achieve perfect parallel position of the work rolls and a constant one Gap or a constant pass line can be reached. In addition, the aim is elaborate ball joints and heavy ball joint stilts to transfer the Avoid straightening forces.
  • the invention is therefore based on the object of a straightening machine at the outset to create the type mentioned, the swivel or tilt yoke positions without the described disadvantages allows.
  • An embodiment of the invention provides that the roller mill and the crossbar are provided with side guides that lead to Machine stands have curved outer surfaces.
  • the guides which are flattened on the side, on the one hand, favor positioning movements and on the other hand support the short flat guides achieved swivel movements of the roller mill and crossbar.
  • the roller leveler 1 has one of two anchored to the foundation Stand 2 existing machine frames. you are through an upper frame cross member 3 and a lower cross member 4 rigid connected with each other. On the upper, adjustable crossbar 5 an upper roller mill 6 is held. A lower roller mill 7 is arranged on the lower crossbar 4; over on both sides the straightening machine 1 provided in the direction of the straightening good Ledges 24 (see FIG. 2) orient the lower roller mill 7 on the cross-beam 4.
  • the upper cross-beam 5 is over the jack 8 adjustable against the lower crossbar 4; each one and arranged on the outlet side at the corners and thus a total of four Pitch cylinders 8 engage the upper crossmember 5.
  • Roller setting wedges 9 are mounted on the lower roller mill 7 and displaceable by a pressure medium cylinder. Every wedge 9 is a bearing carrier wedge 10 for lower straightening rollers 11 and assigned supporting support rollers 12; between the support rollers 12 are web plates, which are the bearings of the straightening rollers take up. Furthermore, there are several upper straightening rollers 13 on their Bale supported, by means of support rollers 14, which are between Web plates of the upper roller mill 6 are. The top Straightening rollers 13 and support rollers 14 are on a bearing carrier wedge 15 stored. Each of the adjacent bearing carrier wedges 15 is on one Support wedge 16 supported, the other side of the upper roller mill 6 is present. The wedge 16 are by one Pressure cylinder movable. The lower and upper straightening rollers 11, 13 are individually driven and with a cardan shaft Drive not shown connected.
  • Both the lower and the upper crossbar 4, 5 is one and on the outlet side, not symmetrically to the machine center outer fixed stops shown against the roller mill 6 and 7 supported. There are also on the inlet and outlet side between the lower crossbar 4 and the roller mill assigned to it 7 or the upper crossbar 5 and the associated Roller mill 6 with the same distance from each other in a row compensation cylinders 17 arranged between the fixed stops or 18. In the area between the compensation cylinders of the upper Crossbar 5 are distributed over the width of the straightening machine 1 several short swiveling in the play area, enlarged in Figure 3 Shown flat guides 19 arranged, the quasi-pivot points form which - as exaggerated in Fig.
  • the upper roller mill 6 and the upper crossbeam when employed 5 in the machine stand 2 leading side guides 22 are flattened at the top and bottom so that they are the machine stand 2 with curved outer surfaces that support the tipping movements are facing.
  • the guides 22 lie in a horizontal plane with the break points 20 and 21.
  • the upper roller mill 6 also projects Web 23, which beak in the working position, into the Area of the lower roller mill 7, the break point 21 being ineffective and the new, downward-moving inflection point takes effect.
