Description
Zweischneidige dünne Rasierklingen aus Stahlblech werden so hergestellt, daß die Klingenform aus dem Band ausgestanzt wird und die Klingen dann einzeln, oder noch ein zusammenhängendes Band bildend, gehärtet und zum Schluß an den Schneidkanten geschliffen und poliert werden. Um die kostspielige Schleifarbeit auf ein Mindestmaß herabzusetzen, ist bereits vorgeschlagen worden, die Grobschleifarbeit, d. h. die Umwandlung der rechteckigen Klingenkanten in spitzwinklige, durch die die Schneide gebildet wird, durch einen Prägevorgang zu ersetzen. Die Erfindung bezweckt eine Verbesserung des Prägewerkzeuges. Es soll durch das neue Prägewerkzeug darauf Rücksicht genommen werden, daß beim Ausprägen der Schneidkanten der dabei dünner werdende Werkstoff nach außen fließt und der Prägestempel ent-Double-edged thin razor blades made of sheet steel are manufactured so that the Blade shape is punched out of the tape and then the blades individually, or one more Forming a coherent band, hardened and finally ground on the cutting edges and be polished. In order to minimize the costly grinding work, it has already been proposed that the rough grinding work, d. H. the transformation of the rectangular blade edges into acute-angled, through which the cutting edge is formed, to be replaced by an embossing process. The invention aims to improve of the embossing tool. The new embossing tool should take this into account that when the cutting edges are formed, the material becomes thinner flows outwards and the die
ao sprechend folgen muß, wenn unzulässige Stauchungen der Klingen vermieden werden sollen. Gemäß der Erfindung wird diese Aufgabe auf die Weise gelöst, daß die Präge«- stempel in ihre Halter derart drehbar eingesetzt sind, daß ihre Druckflächen während des Prägens der Verschiebung des verformten Werkstoffes folgen. Hierdurch wird die Gefahr der Entstehung unzulässiger Stauchungen der Klingen während des Prägens beseitigt.ao speaking must be followed if impermissible compression of the blades is avoided should. According to the invention, this object is achieved in such a way that the embossing «- stamp are rotatably inserted in their holder so that their pressure surfaces during of the stamping follow the displacement of the deformed material. This will make the The risk of impermissible buckling of the blades during embossing eliminated.
Die Zeichnung veranschaulicht das Prägewerkzeug im Querschnitt.The drawing illustrates the embossing tool in cross section.
Der Oberstempelträger 1 und der Unterstempelträger 2 sind auf irgendeine bekannte Weise gehaltert und in der Presse befestigt. Die Klinge 3 ist im Querschnitt der Deut-· lichkeit wegen in übertriebener Dicke eingezeichnet worden. Die linke Kante 4 der Klinge ist im ungeprägten, die rechte Kante S im geprägten Zustande dargestellt. Für jede der vier Schrägkanten der Klinge ist in die Stempelhalter ein Prägestempel 6 mit zylindrischer Gegendruckfläche 7 drehbar eingesetzt. Zwischen den Außenflächen der Stempel und' den Haltern befinden.sich elastische Einlagen 8, unter deren Druck sich die unbelasteten Stempel nach innen gegen die Niederhalter 9, zwischen welchen sich die Klingen befinden, legen.The upper punch carrier 1 and the lower punch carrier 2 are of any known type Way supported and fastened in the press. The blade 3 is in cross section of the German · has been drawn in because of excessive thickness. The left edge 4 of the The blade is shown in the unembossed state, the right edge S in the embossed state. For every of the four beveled edges of the blade is an embossing punch 6 with a cylindrical in the punch holder Counterpressure surface 7 used rotatably. Between the outer surfaces of the stamps and the holders are elastic Deposits 8, under whose pressure the unloaded punch moves inward against the hold-down device 9, between which the blades are located.
Die Wirkungsweise des Prägewerkzeuges ist die folgende. Sobald beim Niedergehen der Stempel der Prägevorgang beginnt, werden die Stempel von dem durch das Zusammendrücken nach außen ausweichenden Werkstoff gleichfalls nach außen gedrängt. Diese Bewegung wird ermöglicht durch die Art der Lagerung der Stempel in ihren Haltern. Auf der rechten Seite der Zeichnung ist die Endstellung der Stempel nach vollendetem Prägevorgang dargestellt, während die linke Seite die Lage der Stempel vor Beginn des Prägevorganges zeigt.The mode of operation of the embossing tool is as follows. As soon as when going down When the stamp starts the embossing process, the stamps are removed from the one by pressing them together outwardly evading material is also pushed outward. This movement is made possible by the nature of the Storage of the stamps in their holders. On the right side of the drawing is the end position the stamp is shown after the stamping process has been completed, while the left side shows the position of the stamp before the stamping process begins shows.
