Die beiliegende Zeichnung stellt eine Zange zum Abscheeren von Bolzen, Draht, Bandeisen etc., sowie in schematischer Darstellung eine zur Kraftübersetzung verwendete Kniehebelvorrichtung dar.The accompanying drawing shows a pair of pliers for shearing off bolts, wire and iron straps etc., as well as a schematic representation of a toggle lever device used for power transmission represent.
Die Zange besteht im wesentlichen aus zwei Handhebeln α und b, dem Messerhalter c, der Scheibe d, dem Druckhebel e, der Deckplatte/ und den Messern g und h. The pliers essentially consist of two hand levers α and b, the knife holder c, the disk d, the pressure lever e, the cover plate / and the knives g and h.
Der festzuhaltende Handhebel α trägt ein Messer g, den Drehbolzen i für den Messerhalter e und die Lagerung bezw. das Widerlager für die Scheibe d. Der zu bewegende Handhebel b ist mit der Scheibe d durch das Vierkant k und die Mutter / fest verbunden, so dafs durch Drehung des Handhebels b die Scheibe d sich ebenfalls dreht und durch das excentrisch angebrachte Widerlager für den Druckhebel e die Bewegung auf letzteren überträgt. Der Druckhebel e drückt mit dem anderen Ende auf das Widerlager am Messerhalter c, der seinerseits, sich um den Bolzen i drehend, sein Messer h an dem am Handhebel α befindlichen Messer q vorbeischiebt.The hand lever to be held α carries a knife g, the pivot pin i for the knife holder e and the storage BEZW. the abutment for the disc d. The hand lever b to be moved is firmly connected to the disk d by the square k and the nut /, so that by turning the hand lever b the disk d also rotates and the eccentric abutment for the pressure lever e transmits the movement to the latter. The other end of the pressure lever e presses on the abutment on the knife holder c, which in turn, rotating around the bolt i, pushes its knife h past the knife q on the hand lever α .
Die Deckplatte/ mit dem in ihr mittelst Gewinde verstellbaren Bolzen 0 verhindert ein Ausweichen des Messerhalters c in seitlicher Richtung. Die Feder ρ sucht den Messerhalter c in geöffneter Stellung zu erhalten.The cover plate / with the bolt 0 adjustable in it by means of a thread prevents the knife holder c from deviating in the lateral direction. The spring ρ tries to keep the knife holder c in the open position.
Das Eigenthümliche der Zange besteht in der zur Kraftübersetzung angewendeten Vorrichtung. Dieselbe besteht theoretisch aus einem Kniehebel, bei welchem die Kraft P an der Verlängerung des einen Hebels m eingeleitet wird. Constructiv ist dieser Hebel als Scheibe mit excentrisch angebrachtem Widerlager für den zweiten Hebel η ausgebildet.The peculiarity of the forceps consists in the device used to transmit the force. Theoretically, it consists of a toggle lever, in which the force P is applied to the extension of one lever m . Constructively, this lever is designed as a disc with an eccentrically attached abutment for the second lever η .
Diese Construction hat den Vorzug, dafs der Hebel m beliebig klein, mithin die Kraft äufserung beliebig grofs gemacht, ferner dafs ein gegebener Weg (im obigen Falle die Länge des menschlichen Armes) ganz für die Arbeitsleistung ausgenutzt werden kann. Aufserdem gestattet die Wahl der Länge des zweiten Hebels η (Druckhebel), sowie des Drehpunktes i vielfache Aenderungen in der Wahl der Kraftübersetzung.This construction has the advantage that the lever m can be made arbitrarily small, and consequently the exertion of force arbitrarily large, and furthermore that a given path (in the above case the length of the human arm) can be used entirely for the work. In addition, the choice of the length of the second lever η (pressure lever) and of the pivot point i allows multiple changes in the choice of power transmission.
Diese Kniehebelvorrichtung ist überall dort verwendbar, wo es sich um Wirkung grofser Kräfte bei entsprechend kleinen Wegen handelt, so z. B. bei Schnittwerkzeugen, Stanzen, Prägemaschinen etc.This toggle lever device can be used wherever the effect is greater Forces in correspondingly small ways acts, so z. B. with cutting tools, punches, embossing machines Etc.
