Definitions

  • the invention relates to a preferably hydraulically or pneumatically acting straightening machine with a receiving device for an elongated workpiece to be straightened, such as solid, hollow profile or tube, and an array of straightening tools with straightening cylinder and straightening die attached thereto.
  • Such a straightening press is in the AT-PS 255 864 specified.
  • An elongated workpiece in particular rail, rod or tubular material, is placed on a guide bed as a receiving device and can be moved thereon to make by means of straightening tools, which include a straightening and two abutments, a bending of the tool in the alignment required extent , In this case, the deflection of the material is limited by means of a protruding limiting member.
  • One difficulty encountered with such straightening presses is a lack of straightening accuracy with flexible straightening capabilities and a lack of straightening speed.
  • the DD 220 518 A1 shows a straightener for straightening long profiled steels, with which the straightening performance of the press should be increased and concave and convex bending of the straightening material should be eliminated without the straightening material must be turned or folded.
  • two straightening cylinders are arranged vertically on the machine frame for straightening over the abscissa of the rail to be straightened and a straightening cylinder horizontally for straightening about the ordinate.
  • On the piston rods of the straightening cylinder are pressure side straightening, which are opposite fixed straightening.
  • a device for straightening a tube with an expander device disposed inside the tube, with which a radially outward force is exerted on the tube wall, for which purpose a radially expandable expander head and at least one straightening saddle are provided, which at a desired position along the Longitudinal axis of the tube can be positioned.
  • an insertable into the tube interior rod or tubular trained spar is provided, and the at least one saddle is adjustable along the longitudinal axis of the spar and slidable by means of bevels from the longitudinal axis of the spar radially outward.
  • the invention has for its object to provide a straightening machine of the type mentioned, with the contour of an elongated tool with high accuracy and directional speed can be calibrated.
  • the straightening tools have at least two straightening cylinders with respective straightening, wherein at least two straightening cylinders are arranged in the same direction with the straightening punches in the direction of the workpiece longitudinal axis.
  • uniformly arranged straightening cylinders with respective straightening the peripheral contour can be quickly and accurately directed, for example, by impanding on the same inner diameter or the same outer diameter from tube to tube.
  • the measures contribute that a control or regulating device is present, by means of which the straightening cylinders are controlled or regulated actuated.
  • One design variant for a quick straightening is that the straightening cylinders are axially offset in pairs with the straightening dies in the longitudinal direction of the workpiece.
  • An accurate calibration is advantageously achieved in that four in the circumferential direction by 90 ° staggered straightening cylinder are available with straightening.
  • Fig. 1 shows schematically the arrangement of tools of a straightening machine for Rundricht relative to a workpiece in axial view, wherein a connection to a control device consists.
  • Fig. 2 shows an embodiment of a straightening machine for Rundhouse with three axially at the same place, but circumferentially offset by 120 ° staggered Richtstempen 21 (straightening shells), one of which fixed and the other two with respective associated cylinders 20 as in the embodiment of FIG 1 are adjustable.
  • an elongate workpiece 1 in this case a tube or round hollow profile, mounted on a receiving device, not shown, in the area between straightening tools, which are connected as essential parts a respective straightening cylinder 20 connected thereto via a carrier 23, transverse to the longitudinal axis of the Workpiece 1 adjustable straightening shells 21 have.
  • the straightening shells 1 can be attached to or with the carriers 23 exchangeably attached to the straightening cylinders 20.
  • the straightening shells 21 are curved on their front side facing the workpiece 1 corresponding to the cross-sectional contour of the workpiece 1 and extend over a certain length in the longitudinal direction of the workpiece 1.
  • the adjustment of the respective carrier 23 with the straightening bowl 21 attached thereto takes place e.g. hydraulically by means of a per se known piston-cylinder unit along an adjustment axis or control axis 22 transversely to the longitudinal axis of the workpiece 1.
  • the straightening shells 21 can be moved individually or in dependence on each other, the operation can be controlled or controlled.
  • Advantageous for accurate calibration is the operation with a control device 30, which takes place in coordination with the contour of the workpiece 1 by means of appropriate sensors and enables a high leveling accuracy at high straightening speed.
  • a control device 30 which takes place in coordination with the contour of the workpiece 1 by means of appropriate sensors and enables a high leveling accuracy at high straightening speed.
  • mechanical or optical equipment or electrical or magnetic measuring devices come into consideration.
  • the straightening cylinder 20 can judge with the straightening shells 21, the pipe up to its example circular contour.
  • the adjustment of the straightening shells 21 takes place by means of the straightening cylinder 20 in each case radially with respect to the workpiece.
  • the calibration is done in terms of diameter and / or ovality.
  • the workpieces or profiles can be calibrated cold or warm (up to the normalization temperature). It is also possible to upsize the material beyond the yield point.
  • an absolute position is specified or predetermined.
  • An advantageous embodiment consists in that the position can be predetermined or calculated on the basis of sensor data from the sensor system and the straightening processes can be controlled or regulated on the basis of this position data. Even with uneven or non-uniform wall thicknesses of pipes straightening by impanding can always be made on the same inner diameter or alternatively on the same outer diameter.
