Definitions

  • the invention relates to a hemming unit for a hemming tool, a hemming tool with a corresponding hemming unit and a method for retrofitting of hemming tools with a corresponding hemming unit.
  • crimping methods are used to form-fit interconnected sheets of the same or different material by cold forming, in particular for the production of body components of motor vehicles, such as vehicle doors or other flat body components Sheet metal, an outer panel with an inner structural plate by crimping or folding of the sheet metal edges is inextricably linked.
  • the sheets are first three-dimensionally preformed and trimmed by means of thermoforming, for example, the outer sheet is given a flange which is angled at about 90 ° during the actual crimping operation by a roll-seaming tool guided along the flange by a robot At least one tool change is required between the individual passes.
  • DE 692 00 577 T2 shows such a Rollbördelclar in which an edge of a workpiece consisting of an outer plate with an upstanding peripheral edge and an inner plate is first bent by means of a Randbiegewalze at a defined angle. After this "pre-flanging" a finish flanging takes place with a different roll orientation or roll geometry, through which the angled sheet is finally bent in a second rolling pass until the previously rising edge finally rests on a peripheral edge of the inner plate.
  • pressing tools are known with crimping jaws, which crimp and join the sheets in several pressing strokes.
  • a flange of the sheet metal parts to be joined is also first vorgebördelt with a Vorbördelbacken before it is then finish beaded with finish flared jaws.
  • the two steps can be carried out in two different pressing tools or with two different geometries of the flanging jaws. In any case, a change of the tool used is required.
  • WO 01/24954 A1 describes a folding device in which only a single folding jaw is used and initially vorbördelt by a horizontal horizontal linear movement a flange of the outer panel. Subsequently, the entire lower tool of the folding device is lifted together with the sheet metal parts receiving folding bed by a lifting movement and pressed against the folding jaws to crimp the already vorgebördelten flange finished.
  • Such pressing tools require a complex hydraulic system to lift the large and heavy lower tool and to press against the folding jaw. Accordingly complex are the required hydraulic units and high investment costs. Also, a control effort is very complex, since the heavy lower tool must be moved as precisely as possible against the folding jaw in order to achieve a sufficient quality of curl.
  • the object of the invention is therefore to provide a crimping tool which is as simple as possible to produce, which enables a short cycle time with the lowest possible investment costs.
  • the greatest possible flexibility in the adaptation of the tool to new workpieces should be achieved.

  • the base element thus provides the possibility of attachment in order to anchor the entire flanging unit and, for example, to connect it to the crimping tool.
  • the support member is linearly movably connected to the base member and can thus be moved relative to this in the first direction of movement.
  • a first slide rail system between the base element and the carrier element may be provided, which provides a guide of the movement in the first direction of movement and in an oppositely directed opposite direction.
  • the slider element is also designed to be linearly movable and for this purpose correspondingly slidably connected to the carrier element.
  • a second slide rail system may be provided between the slider element and the carrier element, which provides guidance of the movement in the second direction of movement and in an opposite opposite direction.
  • the flanging unit itself thus represents a module which independently allows a mobility of a single flanging element in two independently movable directions.
  • This offers the advantage that the crimping element can be used both for pre-crimping and finish crimping. A tool change is therefore not required and thus significantly reduces a cycle time.
  • the modular and independent structure of the entire flanging unit also makes it possible to design these almost independently of the flanging of the crimping tool. A complex movement of the crimping bed is therefore not required.
  • the modular design offers the possibility to equip existing crimping tools, such as Rollbördeltechnikmaschinemaschinee or pressing tools, with the flanging and thus retrofit in a particularly simple manner.
  • the carrier element preferably has a corresponding geometry in order to arrange the first and second slide rail system on the carrier element.
