Description
Es ist bekannt, einen Schmelztiegel in den Sekundärkreis eines Transformators einzuschalten und das Schmelzgut durch Stromwärme auf Schmelztemperatur zu bringen 5 oder an Stelle eines .Schmelztiegels Elektroden anzuordnen, und zwar zum Löten oder Schweißen. Das Wesentliche der Erfindung besteht demgegenüber darin, daß im Sekundärkreis ein Schmelztiegel und ein amIt is known to connect a crucible to the secondary circuit of a transformer and to bring the melted material to the melting temperature by means of electric heat 5 or instead of a crucible to arrange electrodes, for soldering or Welding. The essence of the invention is that in the secondary circuit a melting pot and an am
to Ende von biegsamen Stromleitern angeordnetes Elektrodenpaar vorgesehen ist, um je nach Zweckdienlichkeit das Werkstück entweder in einem Schmelzbad oder zwischen Elektroden bearbeiten zu können. Die Erfindung bezieht sich auf einen Lötapparat, insbesondere für Werkstücke kleinster Dimensionen, wie z.B. solche der Optik, Uhrenindustrie o. dgl., wobei es darauf ankommt, möglichst viel verschiedene Werkstückformenarranged at the end of flexible electrical conductors A pair of electrodes is provided, depending on the expediency, the workpiece either in a weld pool or between To be able to edit electrodes. The invention relates to a soldering apparatus, especially for workpieces of the smallest dimensions, such as those used in optics, the watch industry o. The like. It is important to have as many different workpiece shapes as possible
ao mit ein und derselben Einrichtung bearbeiten zu können.ao to be able to work with one and the same institution.
Die Zeichnung vergegenwärtigt den Erfindungsgegenstand in schematischer Weise. Die Einzelelemente sind wie folgt bezeichnet:The drawing visualizes the subject matter of the invention in a schematic manner. The individual elements are designated as follows:
as α Sekundärwindung des Transformators, b Eisenkern des Transformators, _c Primärwicklung des Transformators, d Schmelztiegel', / gleichzeitig als Lagerzapfen dienender Stromzuführungsansatz des Schmelztiegels, f Handgriff zum Schmelztiegel gehörig, g biegsame Stromleiter, h Elektroden in Zangenform, i Lötobjekt, k verjüngter Querschnitt von Teil e, I Druckknppfkontakt. Der Lötapparat wird durch den Druckknopf I in Tätigkeit gesetzt, wobei entweder das Schmelzgut des Tiegels d zur Erzielung eines Lötbades zum Schmelzen gebracht oder der Arbeitsstrom durch die biegsamen Stromleiter g in die Zange h geleitet wird, um damit Werkstückteile unter gleichzeitiger Hin- 4a durchleitung des Arbeitsstromes mittels Lötmaterials zusammenzulöten. In letzterem Falle dient gleichzeitig der Druckknopf I in vorteilhafter Weise als Stützpunkt für die Zange h, um eine ruhige Haltung der Zange h zu ermöglichen, ohne daß ein besonderer Handgriff zur Betätigung des Druckknopfes / erforderlich· ist. Letzterer Vorgang ist ins* besondere dann wichtig, wenn beide Bedienungshände zur Handhabung der Zange h und zum Auftragen von Lot auf die Werkstücke i o. dgl. gebraucht werden. Die Zange h kann selbstverständlich auch zur Ausführung feiner Schweißarbeiten, also ohne Benutzung) von Lötmaterial verwendet werden, ebenso wie es auch wohl möglich ist, an Stelle des Schmelztiegels eine Glühretorte vorzusehen. Von besonderer Bedeutung ist auch die Schwächung der Lagerzapfen e unmittelbar am Schmelztiegel d an den Stellen k. Der Zweck dieser Maßnahme ist, einen größeren Übergangswiderstand an dieser Stelle zu schaffen, um eine nachteilige Wärmeableitung vom Schmelzgut zu vermeiden, wie es in dem Falle geschehen würde, wenn der Lagerzapfen e an der Stelle k keine Schwächung erfahren würde.as α secondary winding of the transformer, b iron core of the transformer, _c primary winding of the transformer, d crucible ', / at the same time serving as a bearing pin, the power supply attachment of the crucible, f handle belonging to the crucible, g flexible current conductors, h electrodes in pliers shape, i soldering object, k tapered cross-section of part e, I push button contact. The soldering apparatus is activated by pushbutton I , whereby either the melting material of the crucible d is brought to melt in order to obtain a solder bath, or the working current is passed through the flexible conductor g into the pliers h , in order to thereby pass through workpiece parts while simultaneously passing the Working current to be soldered together by means of soldering material. In the latter case, the pushbutton I serves at the same time in an advantageous manner as a support point for the pliers h in order to enable the pliers h to be held steadily without requiring a special handle to operate the pushbutton /. The latter process is particularly important when both operating hands are used to handle the pliers h and to apply solder to the workpieces i or the like. The pliers h can of course also be used to carry out fine welding work, that is to say without the use of soldering material, just as it is also possible to provide a glow cake instead of the melting crucible. The weakening of the bearing journals e directly on the crucible d at points k is also of particular importance. The purpose of this measure is to create a greater contact resistance at this point in order to avoid disadvantageous heat dissipation from the melting material, as would happen if the bearing journal e were not weakened at point k.
