Definitions

  • the Machine for profile rolling with displaceable rollers relates to a profile rolling machine for bending of metal profiles.
  • a bending machine which in its most simple form consists of three rollers, as shown in FIG. 1, is employed.
  • the two lower rollers 1, 2, the transporting rollers, are only able to rotate, while the uppermost roller 3 can be displaced in vertical plane in dependence of the wanted diameter of the finished plate 4.
  • Such bending machine can only provide a bending action in one direction. If S-shaped bending is wanted, this means that the metal 4 after rolling in one direction must be removed from the machine and become inverted and then be bent with an opposite bending. This means low precision and a more expensive operation.
  • the area between the rollers will be narrow with regard to the passing of the metal, when the bending radius is big, causing a pinching and stretching of the metal which finally is bringing more brittleness to the metal introducing risk of rupture during the bending process or during a following loading of the metal.
  • a profile rolling machine for roller bending of metal profiles comprising a first set of rollers with at least two rollers, said rollers being in- tended for abutting on each side of the metal profile, and a set of guiding rollers with at least two rollers intended for abutting on each side of the metal profile.
  • the first set of rollers and the set of guiding rollers are spaced and have passing directions in continuation of each other for receiving and successive transport of the metal profile through the guiding rollers and the first set of rollers, wherein the profile rolling ma- chine is adapted to turning or both displacement and turning of the first set of rollers in relation to the guiding rollers so as to, during the passing of the metal profile through the two set of rollers, be imparting to the metal profile a bending which is determined by this turning and possibly displacement and turning.
  • the metal may be guided in perpendicular direction through the pairs of rollers, wherein a clamping and stretching of the metal is avoided, hi this way is achieved a far more easy and precise observance of the wanted bending radius.
  • the metal profile is passed successively through the guiding rollers and the first set of rollers. But it does not mean that it is necessarily the guiding rollers through which the metal profile at first should be passed. The direction also could be such that the profile is passed in the opposite direction. Under certain cir- cumstances it could in fact be appropriate during the bending process that the metal profile is moved forward and backward between the rollers.
  • the sets of rollers preferably consist of two rollers.
  • the invention is generally not limited to two rollers in each set, but a set of rollers can also comprise more than two rollers, if it should be appropriate, hi the following the described set of rollers are considered, without limitation, as consisting of two rollers being placed opposite each other on both sides of the metal to be bent.
  • leading rollers are situated as displaceable in a dis- placement direction perpendicular to the metal profile's direction of passage between the leading rollers.
  • the leading rollers can for example be situated on a leading block which can be displaced in a recess, wherein the leading block is provided with a threaded hole with internal thread, so rotation of the threaded bar causes the leading block to be displaced in the recess.
  • the first set of rollers are displaceable in only one direction perpendicular to the displacement direction of the leading rollers.
  • Said displacement is practically equivalent to the provided displacement of the leading rollers, perpendicular to it.
  • the roller of the first set of rollers which is intended for abutting on the one side of the metal profile by means of a spacer- connection is connected with the leading roller which is intended for abutting on the opposite side of the metal profile.
  • the first set of rollers can also be placed on a flange so that the roller-shaft is perpendicular to the flange, and the flange can be turned in a plane which is perpendicular to the shafts of the rollers.
  • the flange can be turned according to a rotation axis in the middle between the roller-shafts.
  • this flange may be provided with a tooth profile with a first set of teeth which either is engaging in other teeth on a sliding block so as to cause a turning of the flange when the sliding block is displaced, or is engaging the thread on a toothed bar so as to cause a turning of the flange, when the toothed bar is turned.
  • the profile rolling machine also includes another set of rollers, wherein the first and the second set of rollers are placed on each side of the leading rollers concerning successive transport of the metal profile through the three sets of rollers.
  • leading rollers can be placed so that they are displaceable in a dis- placing direction perpendicular to the metal profile's passing direction between the leading rollers.
  • a displacement of the leading rollers on a slide will then result in a bending of the metal profile in relation to the two sets of rollers on each side of the leading rollers.
  • first set of rollers and the second set of rollers can follow the bended metal profile optimally, it is preferred that the first set of rollers and the second set of rollers are situated on their own flanges, wherein the axis of the rollers is perpendicu- lar to the flange, and the flanges can be turned in a plane which is perpendicular to the axis of the rollers.

Abstract

L’invention concerne une machine de laminage de profilés permettant de mettre des plaques ou des profilés métalliques en forme de S par une seule opération simple. A cette fin, une machine de laminage de profilés servant à cintrer des profilés métalliques à l’aide de cylindres comprend un premier jeu de cylindres (114, 114') comportant au moins deux cylindres, les cylindres venant au contact des deux côtés d’un profil métallique (4, 42, 42'), et un jeu de cylindres de guidage (116, 116') comportant au moins deux cylindres venant au contact des deux côtés du profilé métallique. Le premier jeu de cylindres et le jeu de cylindres de guidage sont espacés l’un de l’autre et présentent des directions de passage se succédant afin de recevoir et d’acheminer successivement le profilé métallique. La machine de laminage de profilés est conçue pour permettre une rotation relative ou un déplacement et une rotation relatifs du premier jeu de cylindres par rapport aux cylindres de guidage de façon à cintrer le profilé métallique lors de son passage à travers les deux jeux de cylindres, le degré de cintrage étant déterminé par le déplacement et/ou la rotation relatifs des cylindres.
