Abstract:
The invention relates to a method for heating metal components using electron irradiation in a vacuum chamber. In order to uniformly heat the metal components in all areas thereof, the invention provides that multilayer holding elements (6) are used for holding the metal components (3) in the vacuum chamber (1). Said holding elements are provided with a layer (9) which faces the electron irradiation, which is resistant to heat and which exhibits good heat absorbing properties. The holding elements are also provided with an inner layer (10) which faces the respective metal component (3) and which exhibits good heat radiating properties. The invention also relates to a device for heating metal components which comprises multilayer holding elements (6). Said holding elements each comprise an outer layer (9) which exhibits absorbing properties and an inner layer (10) which exhibits good heat radiating properties.

Said rolling apparatus (10) comprises a plurality of rolling units (11) disposed aligned along a work axis (X) of said metal product (P). The present invention also concerns the corresponding method for rolling said metal product (P).
Abstract:
Die Erfindung betrifft ein Verfahren zum Laserstrahlhärten von zu härtenden Bereichen (A) eines Garniturdrahtes (10). Dabei wird der Garniturdraht (10) in einer Förderrichtung durch einen Arbeitsraum (26) bewegt. Im Arbeitsraum (26) wird eine Schutzgasatmosphäre durch das kontinuierliche oder diskontinuierliche Einleiten von Schutzgas (G) erzeugt. Im Arbeitsraum (26) wird ein Laserstrahlfeld (27) gebildet, durch das die zu härtenden Bereiche (A) des Garniturdrahtes (10) bewegt werden. Dabei werden die zu härtenden Bereiche (A) erwärmt. Nach dem Austritt aus dem Laserstrahlfeld (27) kühlen sich die zu härtenden Bereiche (A) ab und werden durch das Durchlaufen dieses Temperaturprofils gehärtet. Das Härten in der Schutzgasatmosphäre im Arbeitsraum (26) verhindert das Bilden von Oxidschichten (Verzunderung) und Anlassfarben.
Abstract:
The subject of the invention is a modular device for blowing gas onto the surface of the heat-treated charges, which is part of the blowing system in batch-type chamber furnaces, in which the gas movement during convection heating and cooling is generated by mechanical means and the blowing of gas onto the surface of the charge is carried out by the nozzles fixed on the plate surface and inclined in two directions from the plate axis. The nozzles (3) are arranged on the surface of the support plate (2) evenly with respect to the axis of symmetry (OP) of the support plate (2) and form at least two regular arrays (4), (5). The nozzles (3) are deviated circumferentially from the axis of symmetry (OP) of the support plate (2) by the angle of circumferential deviation (β) of the nozzles and centrifugally by the centrifugal angle (γ), with the angle of circumferential deviation (β) of the nozzles.

Um ein Verfahren zum Temperieren von Fahrzeugkarosserien bereitzustellen, mittels welchem die Temperierung einer innenliegenden Struktur eines Strukturbauteils einer Fahrzeugkarosserie optimierbar ist, wird vorgeschlagen, dass das Verfahren Folgendes umfasst: Positionieren und/oder Bewegen einer Fahrzeugkarosserie relativ zu einer Applikationsvorrichtung zum Applizieren eines temperierten Gasstroms auf die Fahrzeugkarosserie; Richten des Gasstroms auf eine oder mehrere Einlassöffnungen eines Strukturbauteils der Fahrzeugkarosserie.
Abstract:
The invention relates to a forming sheet metal part (1) for a vehicle frame comprising: a first portion (2) being locally heat-softened after the sheet metal part (1) has been formed out. The part (1) further comprises a dedicated three-dimensional distortion-absorbing area (4), defining an internal boundary (6) within which the first portion (2) is to be locally heat-softened after the sheet metal part (1) has been formed out. The distortion-absorbing area (4) is dimensioned such that once said locally heat-softening step has been performed, the internal boundary (6) is adjacent to the first portion (2) and encloses the first portion (2) to absorb the dimensional distortions induced by the locally heat- softened first portion. The invention further relates to a method for producing a forming sheet metal part (1).
