Description

Die Schlagstärke elektr-omagnetischer Hämmer hängt ab von der Größe der magnetischen Anziehungskraft und von der Länge des vorn Hammerbär zurückgelegten Weges. Um die Schlagstärke zu regeln, muß man also wenigstenseinen dieser Werte ändern. Zur Änderung der Anziehungskraft. sind besondere Einrichtunc",cn notwendig, irn einfachsten. Eall ein Widerstand; aber auch ein solcher ist an einem Handwerkzeu- schwer anzubringen und stört durch sein,- Warme. Erfindungsgemäß, wird deshalb die Länge des vorn Hammerbär zurückzulegenden Weges geändert, was durch ein-en verstellbaren Anschlag in einfachster Weise durchführbar ist.The impact strength of electro-magnetic hammers depends on the size the magnetic attraction and the length of the hammerbear covered in front Way. In order to regulate the impact strength, one must therefore at least one of these values change. To change the attraction. special equipment is necessary in the simplest. Eall a resistance; but also one of these is on a handicraft tool. difficult to attach and disturbs by being - warmth. According to the invention is therefore the Changed the length of the path to be covered in front of Hammerbär, which can be adjusted by an-en Stop can be carried out in the simplest possible way.

Die Abbildung zeigt ein Ausführungsbeispiel: i ist der Eisenkern eines Elektromagneten, der durch die SpUle2 intermittierend erregt wird, so daß der Anker, das ist hier der Hammerbär 3, abwechselnd angezogen und los-gelassen wird, wobei er auf den Kopf des Werkzeugs 4, z. B. eines Meißels, schlägt. Zurückgezogen wird der Ankdr 3 durch eine nicht gezeichnete Feder, wobei er sich g geg gen den Anschla-5 legt. Als solch-er dient hier eine um die Achse 6 drehbare exzentrische Scheibe. Wird diese mittels des Handt-,rifis 7 z. B. in der Pfeilrichtung gedreht. so verringert sich der Hub des Hammerbärs, und die Schla'-Istärke nimmt ab. Um eine unbeabsichtigte Verstellung des Anschlags Z, während der Arbeit zu vermeiden, kann er durch beliebige Mittel, 7. 13. durch Rasten, in der jeweili--en 1,age festgehalten werden.The figure shows an exemplary embodiment: i is the iron core of an electromagnet, which is intermittently excited by SpUle2, so that the armature, here the hammerbear 3, is alternately attracted and released, placing it on the head of the tool 4, z. B. a chisel suggests. The Ankdr 3 is withdrawn by a spring (not shown), whereby it lies against the Anchor 5. An eccentric disc rotatable about the axis 6 serves as such. If this is done by means of the hand, rifis 7 z. B. rotated in the direction of the arrow. so the stroke of the hammerbear is reduced, and the sleepy strength decreases. In order to avoid unintentional adjustment of the stop Z during work, it can be held in place in the respective 1, position by any means, 7th, 13th by notching.
