Description

Verfahren zur Herstellung von Pinzettenschenkeln Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von Pinzett:enschenkel.n aus blank gewalzten Bändern von der Stärke der herzustellenden Schenkel. Es ist bekannt. die Schenkel als Rohlinge aus dem Band auszuschneiden und im Gesenk in die Form der herzustellenden Pinzettenschenkel kalt zu schlagen.Method of making forceps legs The invention relates to on a process for the production of tweezers: enschenkel.n from bright rolled Ribbons of the thickness of the legs to be made. It is known. the thigh Cut as blanks from the tape and die in the shape of the one to be produced Beat the tweezer legs cold.

Da die Pinzettenschenkel unterhalb der Stelle, an der die beiden Schenkel einer Pinzette miteinander verbunden werden, zum Zwecke des Federns düng geschlagen werden müssen, werden die Gesenke ungleichmäßig beansprucht, was zur Folge hat, daß sie an der mehr beanspruchten Stelle schneller verschleißen. Hierdurch müssen die Gesenke des öfteren erneuert werden, was mit erheblichen Kosten und großem Werkzeugverlust verbunden ist.Because the tweezer legs below the point where the two legs tweezers are connected to each other, beaten fertilize for the purpose of springing must be, the dies are loaded unevenly, which has the consequence, that they wear out faster in the more stressed area. Have to do this the dies are frequently renewed, which leads to considerable costs and a large loss of tools connected is.

Dieser Übelstand wird gemäß der Erfindung dadurch beseitigt, daß die ausgeschnittenen Rohlinge zur Herstellung der Pinzettenschenkel vor dem Schlagen derselben im Gesenk an ihrem Befestigungsende durch Feilen, Fräsen oder Schleifen keilförmig verdünnt werden, wodurch die Gesenke beim Schlagen der Pinzettenschenkel überall gleichmäßig beansprucht werden.This drawback is eliminated according to the invention in that the Cut-out blanks for making the tweezer legs before striking same in the die at their attachment end by filing, milling or grinding be thinned in a wedge shape, causing the dies when striking the tweezer legs equally stressed everywhere.

Auf der Zeichnung stellen in Ansicht und im Längsschnitt dar: Abb. t einen ausgeschnittenen Rohling zur Herstellung eines Pinzettenschenkels, Abb. 2 'den ausgeschnittenen Rohling mit gemäß der Erfindung verdünntem Befestigungsende und Abb.3 einen .aus dem Rohling im Gesenk kalt geschlagenen Pinzettenschenkel.On the drawing show in view and in longitudinal section: Fig. t a cut-out blank for making a forceps leg, Fig. 2 'the cut blank with the fastening end thinned according to the invention and Fig.3 shows a pair of tweezers that have been cold-hammered from the blank in the die.

Der in Abb. r dargestellte Rohling zur Herstellung eines Pinzettenschenkels wird aus einem Band von der Dicke der herzwstrellenden Pinzettenschenkel ausgeschnitten. Das Befestigungsende wird dann gemäß Abb.2 durch Feilen, Fräsen oder Schleifen keilförmig verdünnt. Beim Schlagen des so vorbereiteten Rohlings im Gesenk wird die in Abb. 2 dargestellte verdünnte Stelle des Rohlings so nachgeschlagen, daß der fertige Pinzettenschenkel die erforderliche Federung erhält.The blank shown in Fig. R for the manufacture of a forceps leg is cut out of a tape the thickness of the tweezers' legs. The fastening end is then made wedge-shaped by filing, milling or grinding, as shown in Figure 2 diluted. When the blank prepared in this way is hit in the die, the process shown in Fig. 2 shown thinned point of the blank looked up so that the finished Tweezer arm receives the necessary suspension.
