Description

Verfahren zur Herstellung von Rasiermesserklingen aus Rohlingen mit vorgearbeiteter Angel. Die Erfindung betrifft ein Verfahren zum Walzen von Messerklingenrohlingen, die zur Herstellung von Rasiermesserklingen dienen.Process for the production of razor blades from blanks with prepared fishing rod. The invention relates to a method for rolling knife blade blanks, which are used to manufacture razor blades.

Rasiermesserklingen mittels Walzen herzustellen, _war bisher nicht möglich, da die starke Verjüngung des Querschnittes zur Schneide hin durch das Walzen ohne ein starkes Krümmen in der Längsrichtung nicht erreicht werden konnte. Die Herstellung durch Schmieden ist aber wegen des Abbrandes, des Abfalles und des Kohlenverbrauches sehr unwirtschaftlich.Making razor blades by means of rollers has not been possible until now possible because of the strong tapering of the cross-section towards the cutting edge due to the rolling could not be achieved without a sharp curvature in the longitudinal direction. the Manufacturing by forging is because of the burnup, waste and coal consumption very uneconomical.

Bei dem neuen Verfahren werden die Rasiermesserklingen in kaltem Zustande in der Querrichtung ausgewalzt, und zwar aus einem gestanzten Rohling von am besten rechteckigem Querschnitt, dessen Dicke zweck"#"näßig dem fertigen Messerrücken und dessen Breite ungefähr der Hälfte der herzustellenden Klinge entspricht.In the new process, the razor blades are cold rolled out in the transverse direction from a stamped blank of best rectangular cross-section, the thickness of which is intended "#" wet the back of the finished knife and the width of which corresponds approximately to half of the blade to be produced.

Das Profil der Klinge kann in gleichmäßig auf dem Umfang verteilten Abständen in die eine Walze längs zur Walzenachse flach liegend eingearbeitet sein, wobei der Messerrücken in der Drehrichtung vorn liegt. Das Werkstück nach Abb. i erhält durch das Auswalzen in der Querrichtung den genauen Querschnitt und die Form der Rasiermesserklinge gemäß Abb. 3, so daß eine nur geringe Nacharbeit erforderlich ist.The profile of the blade can be evenly distributed around the circumference Distances in which a roller can be incorporated lying flat along the roller axis, with the back of the knife at the front in the direction of rotation. The workpiece according to Fig. I obtained by rolling in the transverse direction, the exact cross-section and the shape the razor blade as shown in Fig. 3, so that little reworking is required is.
