Abstract

A device for redressing a deformed element consists of a means of exerting a pressure (3) on the deformed element (2), a means of heating (6) the deformed element, at least one support reinforcement (5) secured to the deformed element, optionally a template (7) forming the original shape of the deformed element and optionally on external support. Also claimed is a method of repowering deformed elements consisting of: introducing the pressure exerting means (3) onto the deformed element on the opposite side of the submitted to deformation; placing the reinforcement (5) so that means (3) is between it and the element; introducing the template (7) between the pressure exerting means and the element, activate the pressure exerting means; heat the deformed element and optionally beat the element with the aid of a former adapted to the sheet thickness, for furnishing a lamp is used to show any lost imperfections to be redressed.

Description

La présente invention concerne un dispositif pour redresser des éléments
métalliques et plastiques endommagés, notamment ayant reçu des chocs tout en gardant les
finitions initiales.The present invention relates to a device for straightening elements
damaged metal and plastic, in particular having received shocks while keeping the
initial finishes.

Actuellement le redressage est fait au moyen d'outils de formes différentes, en
se servant soit du principe du levier, soit par des points de soudure faits à l'extérieur de la partie endommagée, ce qui, généralement, entraîne de la corrosion et neutralise toutes les protections (galvanisées ou autres) de l'élément redressé.Currently straightening is done using tools of different shapes, in
using either the principle of the lever, or by welding points made outside the damaged part, which, generally, causes corrosion and neutralizes all the protections (galvanized or other) of the rectified element.

Le dispositif, selon, l'invention, permet de redresser tout corps creux métallique
et certains plastiques, sans endommager ni la partie métallique ou plastique, ni le traitement
antérieur des parties, et de garder les finitions initiales.The device according to the invention makes it possible to straighten any metallic hollow body
and certain plastics, without damaging either the metal or plastic part or the treatment
previous parts, and keep the initial finishes.

Le ballon (1) peut être inséré très facilement dans le corps creux (2) déformé, la
partie arrière du ballon (8) s'appuie sur le renfort de l'élément, ou sur une barre d'appui
préalablement posée (3).The balloon (1) can be inserted very easily into the deformed hollow body (2), the
rear part of the balloon (8) rests on the element reinforcement, or on a support bar
previously installed (3).

La partie avant du ballon (6) pousse le gabarit (4) de la forme originelle de
l'élément.The front part of the balloon (6) pushes the template (4) of the original shape of
the item.

Le dispositif, selon l'invention, permet entr'autre de remédier aux inconvénients
déjà cités, mais en plus assure une plus grande sécurité pour les personnes opérant la remise
en état des éléments redressés.The device according to the invention makes it possible, inter alia, to remedy the drawbacks
already mentioned, but in addition provides greater security for people operating the delivery
in condition of the rectified elements.

Pas de choc, pas de soudure, pas de bruit. No shock, no welding, no noise.

La description du dispositif, objet de l'invention, est réalisée sur la base de la
remise en état des éléments de carrosserie de véhicules automobiles, mais le procédé peut
également être utilisé dans d'autres domaines où il est nécessaire d'intervenir pour
redresser des éléments métalliques et certains plastiques
Ce but est atteint au moyen de ballons (1) ou de vérins souples, gonflés avec des fluides (5), tels que air, eau, huile, utilisés comme éléments de pressions.The description of the device, object of the invention, is carried out on the basis of the
reconditioning of motor vehicle body parts, but the process can
also be used in other areas where it is necessary to intervene to
straightening metallic elements and certain plastics
This object is achieved by means of balloons (1) or flexible cylinders, inflated with fluids (5), such as air, water, oil, used as pressure elements.

Une autre particularité de l'invention est l'utilisation d'un élément chauffant
servant à dilater et assouplir les éléments à redresser, ainsi qu'un support extérieur (7), dans
certains cas, pour la finition.Another feature of the invention is the use of a heating element
used to expand and soften the elements to be straightened, as well as an external support (7), in
some cases, for finishing.

Une particularité supplémentaire de l'invention est l'utilisation de gabarits préformés (4) servant à ramener l'élément à redresser dans la forme initiale.  An additional feature of the invention is the use of preformed templates (4) used to bring the element to be straightened back to the initial shape.

Un mode particulier d'utilisation du dispositif appliqué à la carrosserie automobile est décrit ci-après. A particular mode of use of the device applied to the automobile body is described below.

Les figures 1, 2 et 3 représentent une vue schématique du dispositif appliqué au redressage d'une porte de voiture.  Figures 1, 2 and 3 show a schematic view of the device applied to the straightening of a car door.
