Definitions

  • the invention relates to devices used to bend profiles. In particular, it is about the so-called (cold) flow bending.
  • a roll bending machine which is equipped with a mandrel shaft, which is positioned in the interior of a profile to be bent in the bending zone.
  • the bending machine consists of a bearing on the inside of the curved profile center roller, a bending roller applied to the sheet outside and a arranged on the outlet side of the profile bending roller which acts on the sheet outer side, against the supporting action of a on the inlet side to the sheet outer side adjacent supporting role.
  • Another bending machine is from the German patent application DE 102004003681 A1 known. In the said patent application is about a novel process, which is also referred to as cold-flow bending, and a correspondingly designed bending machine.
  • the DE 102004003681 A1 describes a device according to the preamble of claim 1.
  • the object is achieved by a device according to claim 1.
  • a device for automated bending of profiles comprises a roller and a multi-part counter-pressure roller, which is arranged spaced from the roller on the opposite side of a profile to be bent.
  • the roller and the counter-pressure roller have roller axes which are parallel to each other.
  • pressure is exerted on the profile to be bent during bending by reducing the relative distance between the multi-part counterpressure roller and the roller and, on the other hand, pressure is exerted in a direction parallel to the roller axes in a controlled manner on the roller parts of the counterpressure roller in order to prevent the deformation of the roller Material flow can be specifically influenced.
  • the principle of the method is based on a rolling mill 20 integrated in a bending machine 10, which rolls the wall thickness of a longitudinal profile 1 according to the desired profile curvature.
  • the corresponding bending machine 10 is in Fig. 6 shown schematically.
  • a special rolling process according to the invention is superimposed on the known roll bending. In this special rolling process, the flow of the material is specifically influenced. This is done by a specially designed rolling mill 20.
  • the rolling process according to the invention can also be used for forming profiles without the usual bending rolls of a bending machine.
  • Both open and closed longitudinal profiles 1 are in the region of a bending head, respectively a bending roller 23, by the interaction of this bending roller 23 with a plurality of rollers (counter-roller 13, 14, Support roller 22) formed.
  • the longitudinal profile 1 to be bent may, but need not, undergo two different process levels in the bending according to the invention.
  • the profile 1 is rolled out with a rolling depth calculated for the respective radius. Because of the wall thickness change thus produced in a targeted manner, the longitudinal curvature of the profile 1 (ie, a curvature in the longitudinal direction of the longitudinal profile 1) arises.
  • a mandrel 24 held inside the profile can transfer the force from a rolling roller 11 to a counter-roller 13, 14 (also called center roller) of the rolling mill 20.
  • a counter-roller 13, 14 also called center roller
  • the longitudinal profile 1 can be bent by the position of a bending roller 23 in its exact form.
  • Z-rollers 18, 19 Perpendicular to the counter-roller 13, 14 according to the invention in the area of the rolling mill 20 so-called Z-rollers 18, 19 are arranged, which do not act directly on the profile 1 but through the counter-roller 14 through (ie indirectly).
  • a part 20 of a device 10 for the automatic bending of longitudinal profiles 1 is shown.
  • the position of the longitudinal profile 1 is indicated only by a reference arrow.
  • the longitudinal axis of the longitudinal profile 1 is perpendicular to the plane of the drawing, ie it runs parallel to the x-coordinate axis.
  • Fig. 1B is a highly simplified cross-section of a longitudinal profile to be bent 1 (hat profile) shown perpendicular to the longitudinal direction.
  • the apparatus 10 has a rolling mill 20 with a rolling head and a multi-part counter-pressure roller 13, 14, 15.
  • a rolling roller 11 serves as a rolling head.
  • the multi-part counter-pressure roller 13, 14, 15 is mounted and arranged with respect to the roller 11 so that there is a small gap therebetween. This gap corresponds approximately to the cross-sectional shape (cross section perpendicular to the longitudinal axis) of the longitudinal profile 1, which in Fig. 1B is shown.
  • the roller 11 are on one side of the longitudinal profile 1 and the counter-pressure roller 13, 14, 15 on the opposite side.
  • the multi-part counter-pressure roller has a first roller axis Z2, which runs essentially perpendicular to the longitudinal axis of the longitudinal profile 1. As mentioned, it is according to the invention in the counter-pressure roller to a multi-part counter-pressure roller.
  • the multi-part counter-pressure roller is also referred to here as a pair of rollers, since it has at least two roller parts 13, 14 which are arranged coaxially.
  • the roller parts 13, 14 may, but need not, sit on a common axle or shaft 21 (see Fig. 6 ), whose center line is in Fig. 1A is indicated as a roller axis Z2.
  • the roller parts 13, 14 are mounted so floating that the relative axial distance between the roller parts 13, 14 is variable.
  • either one of the roller parts can be fixed with respect to the axial position, while the other roller part is displaceable along the roller axis Z2 in the z-direction.
  • both roller parts 13, 14 can be displaceable along the roller axis Z2 in the z direction.
  • Fig. 1A is the axial distance between the roller parts 13, 14 occupied by an elastic disc 15.
  • This disc 15 is optional. It can also be used other resilient or elastic elements that allow a floating mounting of the roller parts 13, 14.
  • the main purpose of the elastic disc 15, or the equivalent means is to push apart the two roller parts 13 and 14 so as to better insert or pull in the longitudinal profile 1 to be reshaped into the rolling mill.
  • the disc 15 and the equivalently acting means are therefore also referred to as designating restoring or spacing elements.
  • the Z-rollers 18, 19 are not delivered until the longitudinal profile 1 is in the rolling mill 20
  • the roller 11 peak the rolling head
  • the multi-part counter-pressure roller can be delivered from the right and left to the longitudinal profile 1 so as to exert a forming force on the longitudinal profile 1.
  • This feed motion is also referred to as Y W -feed (Y W is the rolling axis parallel to the y-coordinate axis).
  • Y W is the rolling axis parallel to the y-coordinate axis.
  • additional rolling forces are used in the region of the rolling mill 20, which act laterally, ie perpendicular to the longitudinal direction of the longitudinal profiles (in the z-direction) (vertical Called pressing).
  • the rolling roller 11 ie, the rolling head
  • the multi-part counter-pressure roller mainly process the surfaces of the longitudinal profile 1 lying in the xz plane, while the perpendicularly acting rolling forces act on the surfaces lying either in the xy plane or lightly in the xy plane lying obliquely (see example Fig. 1B ).
  • the structure of the rolling mill 20 is selected such that in a direction parallel to the first roller axis Z2 controlled pressure is exerted on the roller parts 13, 14, whereby these roller parts 13, 14 in turn laterally applied to the longitudinal profile 1 rolling forces.
  • the controlled pressure is indicated by the double arrows C and D.
  • a first Z-roller 18 with a roller axis Y2 and a second Z-roller 19 with a roller axis Y1 are provided.
  • the axes Y1, Y2 are both substantially perpendicular to the first roller axis Z2.
  • the Z-roller 18 presses in the + z direction against an end region of the roller part 13 and the Z-roller 19 in the -z direction against an end region of the roller part 14.
  • rollers 13, 14, 15 and the roller 11 rotate.
  • Those circumferential surfaces of these rollers which have a radially outwardly facing surface normal roll on the corresponding surfaces of the longitudinal profile lying in the xz plane 1 off.
  • the roller parts 13, 14 it comes to a Sliding or grinding movements with respect to the surfaces of the longitudinal profile 1, which lie either in the xy plane or slightly inclined to the xy plane (see example Fig. 1B ).

  • Each of the roller parts 13, 14 is divided into sections or discs 13.1 - 13.3 and 14.1- 14.3, which have different circumferential diameters. Preferably, the diameter changes continuously along the roller axis Z2 without forming corners or edges.
