(FR) DISPOSITIF ET PROCÉDÉ POUR LE REFROIDISSEMENT ET LA CHAUFFE COMMANDÉS DE PIÈCES MÉTALLIQUES DANS LE CHAMP DE TEMPÉRATURES LORS DU SOUDAGE, DU BRASAGE OU DE LA SÉPARATION THERMIQUE, DU PLACAGE ET DU DURCISSAGE PARTIEL
Abstract:
(DE) Die Erfindung betrifft eine Vorrichtung und ein Verfahren, welches mittels der Vorrichtung durchgeführt wird, für ein gesteuertes Kühlen und/oder Erwärmen metallischer Werkstücke I, II (8,9) im Temperaturfeld (14) beim Schweißen, thermischen Trennen, Löten, Auftragsschweißen oder partiellen Härten. Hierbei gelingt es, durch die Ausbildung einer im Wesentlichen einem Brenner (1), einem thermischen Brenn-, Plasma- oder Laserschneideapparat oder einem Lötapparat in der äußeren Form nachfolgenden konstruierten Vorrichtung, die mit ihm fest verbunden ist und ringförmig angeordnete Kühlgaszuführungen (3) mit Kühlgasaustritten (4) enthält, dass im Bereich des Wirkens vom Temperaturfeld (14) auf ein oder auf mehrere Werkstücke I, II (8, 9) bereits während des aktiven Arbeitens und Vorschubes eines modifizierten Werkzeuges Areale des Temperaturfeldes (14) nacheinander oder auch zeitgleich gekühlt und/oder erwärmt werden können. Die Vorrichtung realisiert ein offenes Verfahren zur Kühlung, Erwärmung des bzw. der zu bearbeitenden Werkstücke I, II (8, 9). Die jeweils Werkstoff- und verfahrensspezifisch optimale Abkühlgeschwindigkeit wird dabei neben der Durchflussmenge besonders über die Temperatur des Kühlgases gesteuert. Dazu wird das zur Kühlung des Temperaturfeldes vorgesehene kryogene Gas in der Mischung eines flüssigen und gasförmigen Anteils verwendet."
(EN) The invention relates to a device and a method which is carried out by means of the device, for the controlled cooling and heating of metallic workpieces I, II (8, 9) in the temperature field (14) during welding, thermal separating, soldering, deposition welding or partial hardening. As a result of the design of a device with a construction which essentially follows the outer contours of a burner (1), a thermal burning, plasma or laser cutting apparatus or a soldering apparatus, said device being firmly connected to a housing and the housing comprising annularly arranged cooling gas supply lines (3) with cooling gas outlets (4), it is possible to successively or also simultaneously cool and/or heat the surface area of the temperature field (14), in the action area of the temperature field (14) on one or more workpieces I, II (8, 9) during the active working and progression of a modified tool. The device implements an open method for cooling and heating the tool(s) which are to be machined I, II, (8, 9). The respective optimum cooling rate specific to the material and method is controlled, in addition to the flow rate, particularly by the temperature of the cooling gas. The cryogenic gas provided for cooling the temperature field is also used in the the liquid and gaseous portions of the mixture.
(FR) L'invention concerne un dispositif et un procédé mis en oeuvre au moyen du dispositif, pour le refroidissement et/ou la chauffe commandés de pièces métalliques I, II (8, 9) dans le champ de températures lors du soudage, de la séparation thermique, du brasage, du placage et du durcissage partiel Au moyen d'un dispositif dont la forme extérieure suit sensiblement un brûleur, un appareil thermique d'oxycoupage, de découpage au plasma ou de découpage laser, ou un appareil de brasage, relié fixement à ceux-ci et comportant des conduites de gaz de refroidissement (3) disposées de façon annulaire, présentant des orifices de sortie de gaz de refroidissement (4), il est possible de refroidir et/ou chauffer de façon consécutive ou simultanée des zones du champ de températures (14), dans la zone d'action du champ de températures (14) sur une ou plusieurs pièces I, II (8, 9), lors du fonctionnement actif et de l'avancement d'un outil modifié. Le dispositif met en oeuvre un procédé ouvert pour le refroidissement et la chauffe de la ou des pièces à usiner I, II (8, 9). La vitesse de refroidissement optimale spécifique au matériau et au procédé est commandée, outre par le débit, notamment par la température du gaz de refroidissement. Le gaz cryogénique servant au refroidissement du champ de températures est employé dans un mélange liquide/gaz..
