Description
Ein gegen das Obermesser von Scheren federndes Untermesser ist bekannt. Bei dieser .Scherenkonstruktion ist als Untermiessiejr eine Blattfeder verwandt worden, die so biefestigt ist, daß die Schrieidfläche desselben einen ständig federnden Druck auf die Schneidflache des Öbermessers ausübt. Natürlich ist man bei Verwendung eines solchen Blattfedermessers in der DimensionierungOne against the upper knife of scissors resilient lower knife is known. In this .Scissors construction is as Untermiessiejr a leaf spring has been used, which is so firmly fastened that the crotch surface of the same constantly exerts resilient pressure on the cutting surface of the outer knife. Naturally one is in the dimensioning when using such a leaf spring knife
ίο nach, oben hin beschränkt, denn eine federnde Wirkung kann von einem solchen Messer nur erzielt werden, wenn die Stärke desselben verhältnismäßig schwach, gewählt wird, und die Folge bei Verwendung eines derartigen Messers ist, daß dasselbe bei einem zu starken Scherdruck zusammenknickt.ίο limited to the top, because a resilient one Effect can only be achieved by such a knife if its strength is proportionate weak, is chosen, and the consequence of using such a knife is that it collapses when the shear pressure is too strong.
Gegenstand der vorliegenden Erfindung ist ein schwingendes Untermesser für Blechscheren. Die Schneidfläche des geraden Untermessers wird durch eine Feder leicht an die Schneidflache des schrägen oder schraubenförmigen Obermessers angedrückt. Durch die besondere Lagerung des Untermessers wird beim Schneiden durch den Scherdruck dieThe subject of the present invention is a vibrating bottom knife for tin snips. The cutting surface of the straight bedknife is easily attached to the The cutting surface of the inclined or helical upper knife is pressed on. Through the When cutting, the shear pressure causes the lower blade to be mounted in a special way
*5 Schneidfläche desselben fest an die Schneidflache des Obermessers· angepreßt.* 5 cutting surface of the same firmly to the cutting surface of the upper knife · pressed on.
Die in Abb. 1 und 2 dargestellte Schere hat ein gerades Obermesser a, ein schwenkbares Untermesser b, welches, durch eine Feder c leicht an das Messer α angedrückt wird. Messer & ist in. Zapfens gelagert. Da die Drehachse des Untermessers von der Schneidebene um ein gewisses Maß entfernt liegt, so entsteht beim Schneiden durch den Scherdruck eine Druckkomponente/, die die Schneidfläche des Untermessers & fest an die Schneidflache des Obermessers a andrückt.The scissors shown in Fig. 1 and 2 have a straight upper knife a, a pivoting lower knife b, which is pressed slightly against the knife α by a spring c. Knife & is stored in the pin. Since the axis of rotation of the lower knife is a certain distance away from the cutting plane, the shear pressure creates a pressure component / that presses the cutting surface of the lower knife & firmly against the cutting surface of the upper knife a.
Ist das Obermesser rund und mit schraubenförmiger Schneidkante versehen (Abb. 4 und s), so entsteht ebenfalls bei richtiger Lagerung des Untermessers eine Druckkomponente, die das Messer fest an das Obermesser^drückt. Selbstverständlich können auch Scheren mit gebogenen oder geschweiften Obermessern mit schwingendem Untermesser ausgebildet werden.If the upper knife is round and has a helical cutting edge (Fig. 4 and s), if the lower blade is correctly positioned, a pressure component is created, which presses the knife firmly against the upper knife ^. Of course, scissors with curved or curved upper blades with swinging lower blades can also be used be formed.
Vorteilhaft werden die bisher erwähnten Obermesser mit einer Schleifphase versehen.The previously mentioned upper knives are advantageously provided with a grinding phase.
