Definitions

  • the invention relates to a bending straightening machine of the type corresponding to the preamble of claim 1.
  • Bending straighteners for elongated straightening goods have long been known as straightening machines for rails.
  • DE-PS 39 015 shows a bending straightening machine with four straightening dies acting from above, below, right and left, which are arranged between straightening abutments arranged on both sides of the straightening die.
  • the section of the straightening good located between the straightening abutments can of course not be straightened completely, but will have deviations from the straightness, which can be pushed down into a predetermined tolerance field by corresponding repetition of the straightening process.
  • the relevant section of the straightening good is therefore not ideally straight, but still has certain slight bends, which are, however, still permissible.
  • the curvature of the section of the material to be straightened is detected by three measuring devices distributed over the length of this section. Measuring devices distributed over the length of the section of the target being machined do not notice a curvature of the target.
  • the invention has for its object to provide a bending straightening machine for elongated straightening material, in which the straightening path between the straightening abutments is considerably shorter than the length of the straightening material, so that even curvatures of the straightening material can be detected or deactivated on a large scale.
  • the "fourth" measuring device can be used to determine how the straightened material behaves outside of the straightening path after it has been advanced and a subsequent straightening section has been straightened. If it is found that the straightening of the preceding straightening section moves, as seen in the conveying direction, an already straightened part of the straightening goods located behind the straightening path out of the predetermined tolerance range, suitable measures can be taken. To further clarify the straightening process, it may be expedient in some cases to assign a fifth measuring device and possibly also further measuring devices to the fourth outside the straightening path. The fourth measuring point and possibly further measuring points thus give the possibility of detecting the effect of the straightening on sections of the straightening material lying outside the straightening path.
  • the bending straightening machine designated as a whole in FIG. 1, comprises a press stand 1 with a passage 2, through which the straightening material 10 can be conveyed in sections along its length.
  • the straightening section 3 (FIG. 1) is determined by straightening abutments 5 and 6 which follow one another in the conveying direction 4 of the straightening good 1o and which are arranged in the press stand 1 offset by four at the same height of the straightening good by 90 ° in its circumferential direction.
  • straightening dies 8 which are also arranged in the same arrangement as the directional abutments 5,6 also offset by four in the circumferential direction of the direction by 90 °.
  • straightening dies 8 When one of the straightening dies 8 is lifted, the straightening material 10 is supported on the two opposing straightening abutments 5, 6 and bends between them. Which of the four straightening stamps 8 is activated depends on the direction of the section of the straightening material 10 located in the straightening section 3, the deflection which is not shown in FIGS. 1 and 2, close to the straightening abutments 5, 6 and the straightening dies 8 arranged measuring devices T1, T2, T3 is detected.
  • the bending straightening machine 100 is assigned a conveyor device 20, the actual length of which is measured according to the length of the straightening good 10.
  • the conveyor 20 comprises a horizontal table 22 supported on supports 21, on which support rollers and two revolving chains 23 are arranged.
  • the chains 23 are driven by a drive 29.
  • the straightening good 10 is carried along the end face by means of an angle 24 fastened to the pair of chains 23, 23.
  • the drive 29 pushes the target 10 in sections determined by the size of the target section 3 according to FIG. 1 from left to right in the direction of arrow 4.
  • the form-fitting entrainment ensures an exact positioning of the straightening good 10 in the bending straightening machine 100.
  • the height of the upper TRum of the chains 23 can be adjusted by shifting the supporting rollers 25 depending on the type of straightening material 10, so that this always passes centrally between the straightening abutments 5, 6 and the straightening dies 8.
  • the links 28 of the rollers 25 can be pivoted by means of a screw spindle 27 actuated by a hand crank 26.
  • a conveyor device 40 is provided on the outlet side of the bending straightening machine 100, which is designed corresponding to the conveyor device 20 and receives the already directed section of the conveyed material 10.
  • Fig. 3 the essential elements of the bending straightener 100 are shown again schematically.
  • the straightening section 3 is determined by the position of the straightening abutment 5, 6.
  • the straightening dies 8 In between act the straightening dies 8.
  • the measuring devices T 1, T 2, T 3 are arranged which scan the position of the outer boundary of the straightening good 10 and thereby determine its curvature between the straightening abutments 5, 6 allow.
  • a fourth measuring device T4 is provided which allows the behavior of the straightening goods outside the straightening section 3 when straightening a preceding section of the straightening article located in the straightening section 3 to be determined.
  • the signals of the measuring devices T1, T2, T3 and T4 are fed via lines 31, 32, 33, 34 to a computer 35 which forms signals for actuating the straightening stamp 8, which, via lines 41, 42, 43, 44, a pressure generator 45 are supplied, which forms hydraulic pressures for the actuation of the four piston / cylinder units 7 of the straightening plunger 8, which are passed on to the piston / cylinder units 7 via the lines 36, 37, 38, 39.
  • the lines 37, 38 are provided for the piston / cylinder units 7, which are not visible in FIG. 3 and act perpendicular to the plane of the drawing.
  • the pressures for the piston / cylinder units 7 are not determined solely by the conditions in the straightening section 3, that is, not only by the signals from the measuring devices T 1, T 2, T 3, but also by the signals outside the straightening section 3 fourth measuring device T4 are taken into account, which determine the effects of a straightening process in the straightening section 3 on a section of the straightening material 1o located outside the same.
  • the distance in the longitudinal direction of the material 1o of the measuring device T4 from the measuring device T3 is in the embodiment substantially equal to the distance between the measuring devices T1 and T2 or T2 and T3 with each other.
  • the measuring devices T1, T2, T3, T4 are, although this is not shown in the schematic representation of Fig. 3, in two planes, i.e. present in the exemplary embodiment in the vertical and in the horizontal plane, in order to be able to detect bends of the target 10 in all directions.
