Abstract
Vorrichtung zum Lichtbogenschweißen mittels Hubzündung von rohrförmigen oder ähnlich geformten Hohlkörpern auf Grundmaterial, insbesondere auf gelochtes oder ungelochtes Blechmaterial, welche Vorrichtung einen Bolzenhalter mit einer an seinem vorstehenden Ende ausgebildeten Spannvorrichtung zur Aufnahme der aufzuschweißenden Hohlkörper und eine Einrichtung zum zentrischen Zuführen von Schutzgas aufweist, dadurch gekennzeichnet, dass in dem Bolzenhalter (1,1') aus nicht-magnetischem Werkstoff koaxial zu dessen Längsachse (10) ein stabförmiger Permanentmagnet (4,4') untergebracht ist.Device for arc welding by means of spark ignition of tubular or similarly shaped hollow bodies on base material, in particular on perforated or non-perforated sheet material, which device has a stud holder with a tensioning device formed at its projecting end for receiving the hollow bodies to be welded on and a device for the central supply of protective gas that a rod-shaped permanent magnet (4,4 ') is accommodated in the bolt holder (1,1') made of non-magnetic material coaxial to its longitudinal axis (10).
Description
Die Erfindung betrifft eine Vorrichtung zum Lichtbogenschweißen mittels Hubzündung von rohrförmigen oder ähnlich geformten Hohlkörpern auf Grundmaterial, insbesondere auf gelochtes oder ungelochtes Blechmaterial nach dem Oberbegriff des Anspruchs 1.The invention relates to a device for arc welding by means of drawn ignition of tubular or similar shaped hollow bodies on base material, especially on perforated or non-perforated sheet material according to the preamble of claim 1.

Aufgabe der Erfindung ist es daher, zur Durchführung der vorstehend geschilderten Schweißaufgabe eine besonders einfache und platzsparende Konstruktion einer Vorrichtung zum Lichtbogenschweißen mittels Hubzündung zu schaffen.The object of the invention is therefore to carry out the welding task described above is a particularly simple one and space-saving construction of a device for arc welding by means of Drawn Arc to accomplish.
Gemäß der Erfindung ist dies bei einer solchen Vorrichtung dadurch erreicht, dass in einem Bolzenhalter aus nichtmagnetischem Werkstoff koaxial zu dessen Längsachse ein stabförmiger Permanentmagnet untergebracht ist.According to the invention, this is at achieved such a device in that in a bolt holder made of non-magnetic material coaxial to its longitudinal axis a rod-shaped Permanent magnet is housed.
Hierbei hat sich die Anmelderin die Beobachtung zunutze gemacht, dass auch das Magnetfeld eines Stabmagneten beim Eintritt in ein ferromagnetisches Blechmaterial eine ausreichend starke, radiale Komponente aufweist, um einen unbedingt notwendigen, umlaufenden Lichtbogen zu erzeugen. Durch die erfindungsgemäße Lösung kann somit ein Ablenken des Magnetfeldes direkt am sowie ausgehend vom Bolzenhalter erzeugt werden. Somit ist durch die Erfindung eine konstruktiv besonders einfache, ausgesprochen kostengünstige und darüber hinaus noch sehr platzsparende Lösung geschaffen.Here, the applicant has the Observation took advantage of the fact that the magnetic field of a bar magnet sufficient when entering a ferromagnetic sheet material strong, radial component to provide an absolutely necessary, circulating arc. The solution according to the invention can thus deflecting the magnetic field directly on and starting from Bolt holders are generated. Thus, by the invention structurally particularly simple, extremely inexpensive and about that very space-saving solution created.
Bei dieser Art Bolzenhalter, in dessen Inneren ein stabförmiger Permanentmagnet untergebracht ist, ist folglich eine zusätzliche Steuereinrichtung für eine Magnetspule nicht mehr erforderlich. Vielmehr kann dieser Bolzenhalter in jede herkömmliche Bolzenschweißeinrichtung eingesetzt werden, bei welcher mit Schutzgas geschweißt wird.In this type of stud holder, in its Inside a rod-shaped Permanent magnet is therefore an additional one Control device for a magnetic coil is no longer required. Rather, this stud holder can in any conventional Stud welding equipment are used in which welding is carried out with protective gas.
Um Schutzgas auch zentrisch zuzuführen, weist der Bolzenhalter an seinem im Schweißgerät gehalterten Ende ein entsprechend ausgebildetes Verlängerungs- oder Zwischenteil mit radial und axial verlaufenden Schutzgas-Zuführbohrungen auf; darüber hinaus ist der im Bolzenhalter untergebrachte, stabförmige Permanentmagnet mit einer zentrischen Bohrung versehen. Bei dieser vorteilhaften Weiterbildung der Erfindung kann durch die zentrische Schutzgaszuführung mit dem Schutzgas eine zusätzliche Wirkung auf der Unterseite von gelochten Blechen erzeugt werden, wodurch das Schweißergebnis weiter verbessert wird.In order to also supply protective gas centrally, points the stud holder at its end held in the welding machine trained extension or intermediate part with radially and axially extending protective gas supply holes on; about that In addition, the rod-shaped permanent magnet housed in the stud holder provided with a central hole. In this advantageous A further development of the invention can be provided by the central protective gas supply an additional protective gas Effect on the underside of perforated sheets are generated which continues the welding result is improved.
