Description

Die Erfindung betrifft Haftkontakte für Schweißarbeiten,, die der Stromzuführung zu den verschweißenden Eisenteilen dienen.The invention relates to adhesive contacts for welding, the Serve power supply to the welded iron parts.

Bei den bekannten Geräten dieser Art besteht der Nachteil, daß die- aus Weicheisen geformten Pole des Magnetsystems einem starken Verschleiß unterliegen, der teils .durch Reibung, teils durch Funkenbildung zwischen dem Kontakt und dem zu verschweißenden Gegenstand verursacht wird;- die Schmorstellen müssen zwecks Wiederherstellung der Kontaktflächen abgeschliffen werden. Da der Werkstoff des Dauermagneten in diesen Geräten unter ariderem einer, hohen Anteil von Nickel und Kobalt enthält, bedeutet das Unbrauchbarwerden durch Verschleiß der Polstücke einen erheblichen wirtschaftlichen Verlust.In the known devices of this type there is the disadvantage that the- poles of the magnet system formed from soft iron are subject to heavy wear, partly through friction, partly through sparking between the contact and the the object to be welded is caused; - the scorching areas must be Restoration of the contact surfaces are sanded off. Since the material of the Permanent magnets in these devices include a high proportion of nickel and Contains cobalt, becoming unusable due to wear of the pole pieces means one significant economic loss.

Die Erfindung vermeidet diesen Nachteil. Sie ist dadurch gekennzeichnet, daß die dem Verschleiß unterliegenden Polstücke oder Teile davon auswechselbar ausgebildet sind oder aus einem Werkstoff mit hoher Versichleißfesitigkeit, schlechter Schweißbarkeit und genügender magnetischer Leitfähigkeit bestehen. Als. solche sind beispielsweise Stähle mit einem höheren Kohlenstoffgehalt als, r 1/o anzusehen. Beide Maßnahmen können auch :gleichzeitig nebeneinander zur Anwendung kommen.The invention avoids this disadvantage. It is characterized by that the pole pieces subject to wear or parts thereof are designed to be replaceable or made of a material with high wear resistance, poor weldability and sufficient magnetic conductivity exist. As. such are for example Steels with a higher carbon content than, r 1 / o should be considered. Both measures can also: be used side by side at the same time.

Ein. Ausführungsbeispiel der Erfindung isst in der Zeichnung dargestellt. Darin bedeutet z einen zylindriechen Block aus einer Magnetlegierung mit hohem Energieinhalt, beispielsweise Aluminium-Nickel-Kobalt-Eisen-Legierung mit magnetischer Vorzugsrichtung, mit den Polen N und S, 2 eine Weichei,senhülse, die als Rückschluß für den. magnetischen Kraftfluß dient und den -Magnet-' block r .mit einem, u nmagnetischen Zwischenrohr 3 und einer eisernen Polplatte q. umschließt, 5 eine Klemmvorrichtung für den Anschluß einer Stromzuführung, 6 einen Handgriff, 7 eine aufgeschraubte, -auswechselbare Schutzkappe, die erfindungsgemäß aus einem Werkstoff von hoher Verschleißfestigkeit, schlechter Schweißbarkeit und genügender magnetischer Leitfähigkeit besteht und so auisgebildet ist, daß sich der Arbeitspol des Dauermagneten bis zu ihren. Außenflächen hin fortsetzt. Zu diesem Zwecke besteht sie aus einem Schraubring 8 und einem Mittelpol 9, zwischen denen der mit einem urmagnetischen Werkstoff ro ausgefüllte Arbeitsspalt liegt. Mit der Außenfläche dieser Schutzkappe wird der Haftmagnet andern zu verschweißenden eisernen Gegenstand :angesetzt, wo er magnetisch haftet und die Stromzuführung bildet.A. Embodiment of the invention eats shown in the drawing. Therein z means a cylindrical block made of a magnetic alloy with a high energy content, for example aluminum-nickel-cobalt-iron alloy with a preferred magnetic direction, with the poles N and S, 2 a soft, senhülse, which as a conclusion for the. magnetic flux and the - Magnet- 'block r .with a, u nmagnetischen intermediate tube 3 and an iron pole plate q. encloses, 5 a clamping device for connecting a power supply, 6 a handle, 7 a screwed-on, replaceable protective cap, which according to the invention consists of a material of high wear resistance, poor weldability and sufficient magnetic conductivity and is so auisges that the working pole of the permanent magnet is up to theirs. To the outside areas. For this purpose it consists of a screw ring 8 and a center pole 9, between which the working gap filled with a primordial magnetic material ro lies. With the outer surface of this protective cap, the holding magnet is attached to the iron object to be welded: where it adheres magnetically and forms the power supply.

Dieses Beispiel stellt lediglich eine Ausführungsform der Erfindung dar, die jeweils dergewünschten Verwendung an@gepaßt werden kann.This example represents only one embodiment of the invention which can be adapted to @ according to the desired use.
