Description
Im Schlosserhandwerk, vor allem im Eisenkonstruktionsbau, werden Kontrollkreise um die zu bohrenden oder zu stanzenden Löcher gemacht. Die Kreise werden mit dem Zirkel gezogen, was sehr umständlich ist. Schneller schlägt man sie mit einem Kreis-Anreißkörner ein.In the locksmith's trade, especially in iron construction, there are control circles around the holes to be drilled or punched. The circles are with the Circle drawn, which is very cumbersome. You can hit them faster with a circular marking punch a.
Bei den bisherbekanntenKreis-Anreißkörnernbestanden Körner und Anreißring aus einem Stück. Damit die Körnerspitze in das vorgekörnte Loch eingesetzt werden konnte, stand sie etwas über die Ebene des Anreißringes hinaus. Der Körner nutzte sich aber viel schneller ab als der Anreißring, so daß das Werkzeug vorzeitig unbrauchbar wurde. Auch durfte nicht zu tief vorgekörnt werden, weil sonst die Körnerspitze seitlich Luft hatte, was bewirkte, daß der Kontrollkreis nicht genau konzentrisch um den vorgekörnten Punkt lag. Diese Nachteile werden durch die Erfindung beseitigt.The previously known circular marking punches consisted of punches and a marking ring out of one piece. So that the center punch can be inserted into the pre-punched hole could, it stood a little beyond the level of the marking ring. The grain took advantage but much faster than the scribe ring, so that the tool prematurely unusable became. It was also not allowed to pre-grain the grain too deep, because otherwise the grain point there was air at the side, which meant that the control circle was not exactly concentric around the pre-punched point. These disadvantages are eliminated by the invention.
Die Erfindung besteht in einem Kreis-Anreißkörner mit axial beweglichem Zentrierkörner.The invention consists in a circular scriber with axially movable Centering center.
Die zu bohrenden Löcher können jetzt sofort tief genug vorgekörnt werden. Die weit vorstehende Spitze des Zentrierkörners bei dem neuen Werkzeug füllt auch ein tief vorgekörntes Loch vollständig aus, so daß der Kontrollring genau konzentrisch um das angekörnte Loch eingeschlagen wird.The holes to be drilled can now be pre-grained deep enough immediately will. The protruding tip of the centering punch on the new tool fills also completely cut out a deep pre-grained hole so that the control ring is exactly concentric is hammered around the punched hole.
Das neue Werkzeug gestattet nicht nur ein genaueres, sondern auch schnelleres Arbeiten, weil die weit vorstehende Zentrierkörnerspitze schneller und sicherer in das vorgekörnte Loch eingeführt werden kann.The new tool allows not only a more precise, but also faster work because the protruding centering punch tip is faster and faster can be inserted more securely into the pre-punched hole.
In den Fig. i bis 5 sind Ausführungen dargestellt. Die Fig. i und 2 zeigen den Körner a mit der Spitze b, dem Ansatz c und den Führungskanten d, Der Stahlkörper e mit dem ..Xnre'ißring f und dem Kopf g hat im Innern eine Bobrung, in welcher der elastische Körper h (Gummi, Feder o. dgl.) und die Führungsbüchse i, welche durch den Sprengring j gesichert ist, untergebracht sind. Die Büchse i dient zur Führung und Hubbegrenzung des Körners a.In FIGS. I to 5 , embodiments are shown. Figs. I and 2 show the grain a with the point b, the approach c and the leading edges d. The steel body e with the ..Xnre'ißring f and the head g has a curve inside in which the elastic body h (Rubber, spring or the like) and the guide bush i, which is secured by the snap ring j , are housed. The sleeve i is used to guide and limit the stroke of the grain a.
In denFig. 3 und4 ist eine einfachereAusführung dargestellt. Der Körner a ist unmittelbar in dem Stahlkörper e geführt. Ein Stift k dient zur Hubbegrenzung. In Fig. 5 ist der Körner a um go' gedreht dargestellt, so daß die Ausf räsung 1, in welcher sich der Stift k bewegt, zu erkennen ist. Solche und andere Au ' sführungen mit elastischer oder nicht ela.stischer Zentrierkörnerbewegung sind möglich. So können beispielsweise bei kleinen Kreis-Anreißkörnern der Stahlkörper e zweiteilig zusammenschraubbar ausgeführt werden, wodurch sich die besondere Anbringung einer Hubbegrenzung erübrigen würde.In fig. 3 and 4 a simpler embodiment is shown. The grain a is guided directly in the steel body e. A pin k is used to limit the stroke. In Fig. 5 , the grain a is shown rotated by go 'so that the recess 1, in which the pin k moves, can be seen. These and other Au 'sführungen with elastic or non ela.stischer Zentrierkörnerbewegung are possible. For example, in the case of small circular scriber marks, the steel body e can be designed to be screwed together in two parts, which would make the special attachment of a stroke limiter superfluous.
An Stelle des elastischen Körpers kann auch ein Schiebering oder Stift angeordnet werden, mit dessen Hilfe der Zentrierkörner von Hand nach vorn geschoben wird.A sliding ring or pin can also be used in place of the elastic body be arranged, with the help of which the centering punch is pushed forward by hand will.
