Description
Mit Preßluft betriebene Vorrichtung zum Aufschweißen von Schnellstahl-oder Hartmetallplättchen auf einen Stahlkörper Gegenstand der Erfindung ist eine mit Preßluft angetriebene Vorrichtung zum Aufschweißen von Schnellstahl- oder Ilartm:tallplättchen auf Drehstahlkörper o. dgl. Mit Preßluft :betriebene Vorrichtungen sind zwar an sich bekannt. Ihrer Anwendung zum Aufschweißen von Schnellstahl- oder Hartmetaflplättchen würden sich jedoch Schwierigkeiten entgegenstellen, weil es Voraussetzung für einer. guten Halt der Plättchen ist, daß sie vor Beginn des Schweißvorgangs genau ili der vorbestimmten Lage festgehalten werden und der auf den Drehstahlkörper bei der Yerschweißung ausgeübte Druck immer iri genau senkrechter Richtung erfolgt.Device operated with compressed air for welding high-speed steel or Hard metal plate on a steel body The invention is a with Compressed air driven device for welding on high-speed steel or Ilartm: tall plates on turning steel body or the like. With compressed air: operated devices are on known. Your application for welding on high-speed steel or carbide plates would face difficulties, however, because it is a prerequisite for one. The platelets are held well by the fact that they are exactly the same before the start of the welding process predetermined position are held and on the turning steel body during the Yerschweißung The pressure exerted always takes place in an exactly vertical direction.
Diese Bedingungen werden bei Benutzung der Erfindung erfüllt. Sie besteht im wesentlichen darin, daß der preßluftbetätigte Prellstempel in dem auf das Hartmetallplättchen aufgelegten Preßstiick, ebenso wie der den L uftdruckzylinder tragende Arm im Gestell der Vorrichtung, in einem Kugelgelenk gelagert ist.These conditions are met using the invention. she consists essentially in the fact that the compressed air-actuated buffer ram in the The pressed piece placed on the hard metal plate, as well as the pneumatic cylinder supporting arm in the frame of the device, is mounted in a ball joint.
In der Zeichnung ist ein -Atisfülirtings-Beispiel der Erfindung dargestellt.In the drawing, an -Atisfülirtings example of the invention is shown.
Der glühend gemachte Drehstahlkörper a mit dein aufzuschweißenden, gleichfalls glühenden Plättchen b wird durch die Einspannvorrichtung c unverrückbar auf einer Unterlage aufgespannt.The red-hot turning steel body a with your to be welded on, Likewise glowing plate b is immovable by the clamping device c stretched on a base.
Auf das Plättchen b stützt sich der an seiner Unterseite flache Körper e ab, der im Kugelgelenk d gelagert ist. Vor Beginn des Schweißens wird das Auflagestück e mittels der Kolbenstange f, die durch den Hebel g oder die Feder h betätigt werden kann, auf das Plättchen b gepreßt und hält dasselbe in seiner vorbestimmten Lage fest. Daraufhin wird durch das Ventil i in den Zylinder lz l:'reßluft eingelassen, die auf den Kolben 1 einen so starken Druck ausübt, daß die Verschweißung zustandekomint. Das Zylindergehäuse ist an dem im Kugelgelenk na gelagerten und durch die Schraube il feststellbaren Tragarm p festgemacht und kann durch (las Gewinde o in seiner Höhenlage verstellt werden. Durch das Kugelgelenk d am unteren Ende der Kolbenstange j sowie durch die Höheneinstellbarkeit des L uftdruckzylinders k und schließlich durch das Kugelgelenk m am Tragarm p wird eine freie Beweglichkeit der Kolbenstau ge f bewerkstelligt, so daß die Gewähr besteht, daß der auf das Werkstück ausgeübte Druck genau senkrecht wirkt.The body e, which is flat on its underside and is supported in the ball joint d, is supported on the plate b. Before starting the welding, the support piece e is pressed onto the plate b by means of the piston rod f, which can be actuated by the lever g or the spring h, and holds it in its predetermined position. Thereupon air is let into the cylinder lz l: 'through the valve i , which exerts such a strong pressure on the piston 1 that the welding comes about. The cylinder housing is fastened to the support arm p, which is mounted in the ball joint na and can be locked by the screw il, and its height can be adjusted by (las thread o. By means of the ball joint d at the lower end of the piston rod j as well as the height adjustability of the air pressure cylinder k and finally through the ball joint m on the support arm p free mobility of the piston jam ge f is accomplished, so that there is a guarantee that the pressure exerted on the workpiece acts exactly perpendicular.
