Description

Verfahren zur Herstellung eines partiell zu erhitzenden Widerstands-Heizkörpers Bei kleiner Spannung und großer Stromstärke durch \ iederfrequenztransformatoren erhitzhare Bretitistifte für Holzbrandmalerei beispielsweise werden bekanntlich hergestellt, indem Draht oder Hand aus Chromnickel in spitzem Winkel gebogen und an den Schenkelkanten nach der Biegungsstelle hin kotiiscli verlaufend abgeschliffen wird, so daß eine Spitze entsteht, die infolge Querschnittsverminderung Höchsttemperatur annimmt, während die laidett der Schenkel nur wenig erwärmt werden.Process for the production of a partially heated resistance heater With low voltage and high amperage through low-frequency transformers Heat-hard Britti pencils for wood fire painting, for example, are well known made by wire or hand bent from chrome nickel at an acute angle and Sanded off kotiiscli on the leg edges running towards the point of bend is, so that a peak is formed, the maximum temperature due to the reduction in cross-section assumes, while the laidett of the thighs are only slightly warmed.

Die an sich schon geringe Stabilität solcher Draht- oder Bandkörper insbesondere gegen Verbiegen und Verdrehen, zumal in glühendem Zustande, ist mithin geschwächt durch Verkleinerung des Querschnittes an der aktiven Glühzone, welche bereits heim Biegen durch Ausrecken eine Verschlechterung der Festigkeitseigenschaften infolge Spannungen und Rißhildung erlitten hat. Um von vornherein Kaltbruch zu vermeiden, mußte der Biegewinkel groß genug gehalten werden, weshalb die weit auseinanderliegenden Schenkelenden eine raumsparende Einbauweise nicht zulassen.The inherently low stability of such wire or band bodies in particular against bending and twisting, especially in a glowing state, is therefore weakened by reducing the cross-section of the active annealing zone, which already at bending by stretching a deterioration of the strength properties suffered as a result of tension and cracking. In order to avoid cold breakage from the outset, the bending angle had to be kept large enough, which is why the widely spaced Leg ends do not allow a space-saving installation.

Nach der vorliegenden Erfindung wird ein stabiler Heizkörper von kleinstem Raumbedarf hergestellt aus einem einheitlichen Ganzen ohne jegliche Veränderung der Materialstruktur, und zwar lediglich durch entsprechendes Ausformen eines ,oder mehrerer nicht durchgehender Trennschlitze in der Weise, daß dadurch ein leitend verbundenes Leiterschenkelpaar entsteht und durch Heranführen eines Schlitzes an den partiell zu erhitzenden Bereich des Heizkörpers der Leiterquerschnitt an dieser Stelle am kleinsten gehalten wird. Es genügen dünne Spalte, so daß zumal bei Ausfüllung der Hohlräume mit festen Isolierstoffen eine große Stabilität erreicht wird.According to the present invention, a stable radiator becomes the smallest Space requirements made from a unified whole without any Modification of the material structure, only through appropriate shaping one or more non-continuous separation slots in such a way that thereby a conductively connected pair of conductor legs is created and by bringing one Slot on the area of the radiator to be partially heated, the conductor cross-section is kept smallest at this point. Thin gaps are sufficient, so that especially when the cavities are filled with solid insulating materials, great stability is achieved will.

Ein solcher Heizkörper z. B. in stiftförmiger Ausbildung ist hervorragend geeignet als Brennnadel für Holz oder auch als Heizer für eine vorgesetzte Kupferkappe in Lötkolbenform, wobei die Kuppe des Glühstiftes direkt die Spitze des Löt- kolbens von innen her erhitzen kann.Such a radiator z. B. in the form of a pen is ideally suited as a burning needle for wood or as a heater for a copper cap in the form of a soldering iron, whereby the tip of the glow plug can directly heat the tip of the soldering iron from the inside.

PATENTANSPRUCH: Verfahren zur Herstellung eines partiell zu erhitzenden Widerstands-Heizkörpers, dadurch gekennzeichnet, daß in einem der gewünschten Form des Widerstandskörpers entsprechendem Stück Widerstandswerkstoff ein oder mehrere nicht durchlaufende Trennschlitze angebracht werden derart, daß dadurch ein leitend verbundenes Leiterschenkelpaar entsteht und der Bereich kleinsten nuerschnittes desselben an der gewünschten Stelle höchster Temperaturaufrnahme liegt. PATENT CLAIM: A method for producing a partially heated resistance heater, characterized in that one or more non-continuous separating slots are made in a piece of resistance material corresponding to the desired shape of the resistance body in such a way that a conductively connected pair of conductor legs is created and the area of the smallest cross-section thereof is at the desired point of highest temperature absorption.
