Definitions

  • the invention relates to a device for bending profiles or rod material, in particular unbalanced and open profiles or rod material according to the preamble of claim 1 and a method according to the preamble of claim 15.
  • profiles and bar material is a frequently occurring manufacturing requirement for the production of workpiece blanks or finished products made of profiled starting material.
  • bending operations on profiles and bar material can be carried out largely error-free with conventional form-bonded or free-form bending methods such as three-point bending, three-roll round bending, Rotationszugbiegen or Gesenkbiegen.
  • conventional form-bonded or free-form bending methods such as three-point bending, three-roll round bending, Rotationszugbiegen or Gesenkbiegen.
  • profile shapes and rod cross-sections which can not be bent with conventional form-fitting or free-form bending processes due to various technical and economic reasons, without causing corresponding cross-sectional deformations.
  • the cross-sectional shape and the material to be reshaped plays a major role.
  • the profiles are already fully supported by the tools in form-bonded processes, such as in Rotationszugbiegen or the Gesenkbiegen.
  • the tool supports the side walls of the profile, so that a collapse or twist is not possible.
  • transverse force-free bending processes offer a relevant alternative to reduce or completely avoid cross-sectional distortions.
  • the rotation of the cross-section in the kinematic or formed bending process is basically caused by the fact that the bending plane is not aligned parallel to the symmetry plane of the profile (unbalanced loaded bending).
  • shear force shear stresses are then caused, which give rise to a torsional moment, which causes the rotation.
  • special countermeasures are made. For example, in the three-roller bending next to the bending rollers other support rollers are used, which hold the profile by the action of an additional transverse force in the plane and thus prevent twisting.
  • Querkraftbeaten bending methods have been proposed in which the necessary bending moment is introduced directly via a clamping point in the profile to be bent or the rod to be bent and thus no shear stresses occur.
  • the object of the present invention is therefore to specify a production method in which profiles and rod materials of any type and any cross-section are flexible be bent so that bending typical, but unwanted cross-sectional deformations, such as the collapse or twisting of profiles, are prevented.
  • the invention relates to a device for bending profiles or bar material, in particular unbalanced and open profiles or rod material, comprising mutually pivotable bending members which receive the profile or rod material and hold punctually and transfer locally by means of bending moment introduction into a curved configuration.
  • Such a generic device is further developed in that at least two along the bending line of the profile or rod material spaced bending members are fixed to each other and pivotable relative to each other that a relative pivoting of the bending members to each other deforms the profile or rod material bending locally, wherein along the Bending line of the profile or rod material at least partially elastically deformable support elements are arranged on the outer sides of the profile or rod material between the bending elements and the relative pivoting of the bending members to each other, the support elements also bends, wherein the support elements support the bending profile or rod material.
  • the bending device usually includes a plurality of pivotally interconnected bending members.
  • the bending geometry of the profile or bar material to be produced is defined by the relative orientation of the bending elements relative to one another.
  • the individual bending members can be pivoted relative to each other with a defined torque or a defined pivot angle to each other, whereby the bending device thus formed gains a high degree of flexibility, as along the axis of the profile or rod material with only one set of bending elements different bending radii and bending angles can be adjusted can. It is therefore also a kinematic bending process.
  • several bending elements arranged one behind the other in combination with the profile or rod material on the outside supporting and elastically mitverformten support elements eg consisting of layered leaf springs can be in the profile or rod material achieve a defined torque introduction.
  • the device according to the invention is also particularly suitable for the bending of thin-walled profiles that are sensitive to kinking and wrinkling or require a special temperature with simultaneous support during molding.
  • the method is very well suited for the subsequent correction of already generated curvatures, since the bending apparatus can assume arbitrarily curved initial states.
  • such a number of bending members are fixed to each other that the profile or bar material is supported substantially along the entire length of its bending line of bending members.
  • Such a number and arrangement of bending members will always be preferable if the profile or bar material is to be bent along the entire length or is so unstable due to its material or cross-section that support of the profile or bar material over the entire length is required.
  • the number of bending members depending on the length of the profile or rod material to be bent and the bending curves to be taken and the changes of these bending curvatures can be selected.
  • the number of bending members smaller and their distance may be greater.
  • such a number of bending members may be secured together and arranged so that the profile or rod material is supported along only at least a portion of its bending line of flexure members.
  • the number and the arrangement of the bending elements along the bending line can also be selected accordingly and provided only where the bending is to be carried out.
  • the other sections of the profile or bar material need no support by the bending members.
  • the bending members have holding devices for receiving the profile or bar material to be bent.
  • the holding devices are formed like a pliers and the profile or bar material opposite to the profile or bar material attacking receive between them and hold during bending, a secure receiving and supporting the profile or bar material can be realized during bending.
  • the holding devices take the profile or rod material clamping between them and take over the task of positioning relative to the pivotable bending members securing the definition of the profile or rod material relative to the Biegelieder.
  • the bending members are fixed to one another such that the desired bending line of the profile or rod material can be adjusted by relative pivoting of the sequence of the bending members relative to one another along the bending line.
  • the type of determination of the bending members and thus the relative mobility of the bending elements to one another determines the achievable bending operations.
  • the bending members are fixed to each other via a simple two-dimensional pivoting mechanism, such as a hinge, bending of the profile or bar material in a plane becomes possible.
  • the bending members are fixed to each other pivotally to each other so that the desired bending of the profile or rod material can be made three-dimensionally curved.
  • the relative pivoting movements should be controlled driven between the bending members, so that the relative pivoting can be performed and controlled automatically by a defined angle or with a defined pivoting moment.
  • the pivoting movements of each bending member are independent of the other bending members controllable.
  • drives for these pivotal movements of the individual bending members are electrical or pneumatic or hydraulic or mechanical drives in question, possibly via transmission, translation, lever or the like.
  • the bending members pivot relative to each other.
  • the bending members and the holding devices are arranged on a base body.
  • a main body can take on the one hand the necessary bearings for the bending members and the holding devices, but also supported on the other side, preferably on a base plate relative to the environment of the device. Since the Relativverschwenkung the benders to each other causes a chain-like coupled, planar or spatial movement of the bending members, the reaction forces must be supported and discharged to this pivoting movement and the bending of the profile or rod material. In the case of two-dimensional bending operations, for example, this can be done by placing the bending members on a solid base such as a base plate.
  • the support elements are so formed and elastically deformable that they support the profile or rod material in at least one spatial direction in the deformation of the profile or rod material and prevent unwanted bending errors.
  • the support elements in the present invention have two purposes, namely on the one hand to ensure a continuous bending line between the individual bending members and on the other hand, the support of the profile or bar material in carrying out the bending operations.
  • the support elements extend at least between two adjacent Biegeliedern and are fixed to the bending elements, for example with the holding devices by clamping. In general, however, the support elements preferably extend over several or all bending members.
  • the elastically deformable provide Support elements for the bending of the profile or bar material with a continuously formed bending line, which means that the bending line has no kinks or other irregularities that you normally want to avoid when bending.
  • the profile or bar material can at least partially be supported on these along the bending line extending support elements in the implementation of the bending operation by the Relatiwerschwenkung the flexures, whereby impermissible deformations of the profile or bar material can be reduced or avoided altogether.
  • the support elements Since the support elements also bend, but elastically bend due to their inherent elasticity in the pivoting of the bending members and this bend is equal to the desired bending of the profile or bar material, the profile or bar material remains supported during the entire execution of the bending by the bending members. In the simplest case of a two-dimensional plane bending operation, this support can take place in a spatial direction, for example by the support elements being formed as leaf spring-like elements and on the outer surface of the profile or rod material fitting. Thus, the profile or rod material can be supported exactly in the direction of the bend on the leaf spring-like support elements.
  • a plurality of support elements are arranged along the bending line of the profile or bar material so as to support the profile or bar material in more than one spatial direction during the deformation of the profile or bar material, e.g. first support members are disposed along the bending line of the profile or rod material so as to support the profile or rod material in a spatial direction, and second support members are disposed along the bending line with a perpendicularly oriented supporting action.
  • first support members are disposed along the bending line of the profile or rod material so as to support the profile or rod material in a spatial direction
  • second support members are disposed along the bending line with a perpendicularly oriented supporting action.
  • the support elements may be e.g. be loaded by compressive forces and thus bring a bias in the profile to be bent.
  • the support elements may have one or more individual bodies, wherein when using a plurality of individual bodies, the plurality of individual bodies may form a composite.
  • a plurality of leaf spring-like formed individual body are arranged in a packet-like layered to form a support element. This can be achieved exactly where there is a high support resistance by the nature and thickness of the stratification of the leaf spring-like support elements, where it is needed and also large acting from the bending of the profile or rod material forces are securely supported.
  • Wire-like support elements may e.g. advantageously provide support for three-dimensional bending operations by orienting the wires in accordance with the bending deformation.
  • the support elements have at least one additional sliding layer and / or separating layer, which bears against the surface of the profile or rod material and / or improves the sliding movement between the profile and the supporting element and / or of supporting elements formed from individual bodies. Since relative movements between support element and profile or e.g. between the leaf springs formed between the individual leaf springs can be improved by such a sliding layer and / or separating layer, the relative movement between the profile and the support element or between the leaf springs of the support element or dei surface of the profile is not damaged.
  • a feed device applies a feed force in the direction of the course of the bending members or the bending line on the profile or rod material to be bent and so, matched to the movements of the actual bending operations with the bending members, the profile or rod material through the chain Promotes bending members through.
  • the feed device can be arranged at the inlet of the profile or rod material in the arrangement of the bending members and exert a sliding effect on the profile or bar material to be bent, but it is also conceivable that the feed device is arranged at the outlet of the profile or rod material from the arrangement of the bending members and exerts a pulling action on the profile or bar material to be bent.
  • the choice of the arrangement depends primarily on the resistance of the profile or rod material against train or pressure, ie labile profiles or rod material are usually drawn through the bender members rather, more stable profiles or rod material can also be pushed through.
  • the bending members along the bending line of the profile or bar material to be bent should take their deformed along the bending line configuration synchronously to the action of the feed device, ie the feed device always works in the breaks of the actual bending operations.

  • the profile or rod material is locally bent, wherein at least partially arranged between the bending members, elastically deformable support members by the relative pivoting of the bending members also mitgebogen be supported and the support elements while the bending profile or rod material.
  • the profile or bar material to be bent is introduced into the bending members in the undeformed or pre-deformed state and the bending members are subsequently brought into the end-deformed configuration along the bending line simultaneously or successively.
  • a kind of kinematic chain of the bending members due to the independent pivotability of each bending member at the same time on all Biegegliedern or in temporal / spatial coordination of individual bending members perform the bending deformation of the profile or rod material, whereby a wide variability and technological adaptability of the bending operations can be guaranteed.
  • the bending members are pivoted independently of each other with a predetermined torque and / or a predetermined angle to each other, so that, if necessary, at each bending member different bending parameters for the local bending of the profile or rod material can be adjusted.
  • the secure support of the profile or bar material in the bending deformation is ensured by the fact that arranged on the bending members holding devices form opposite local recordings for the profile or rod material. These holding elements virtually form the contact surfaces for the profile or bar material within the bending members and position the profile or bar material relative to the bending member.
  • the support elements are designed and elastically deformed such that they support the profile or rod material in at least one spatial direction during the deformation of the profile or rod material and prevent unwanted bending errors.
