Die
Aufgabe der vorliegenden Erfindung ist ein verbessertes Verfahren zur Herstellung von sechseckigen Sicherungsscheiben mit keilförmigen Ebenen, V-förmigen Nuten und Kanten auf Ober- und Unterseite, welches kostengünstig ist und eine hohe Präzision ermöglicht.task The present invention is an improved method of preparation of hexagonal lock washers with wedge-shaped planes, V-shaped grooves and edges on top and bottom, which is inexpensive and high precision allows.
Diese Aufgabe wird durch ein Verfahren mit den Merkmalen des Anspruchs 1 gelöst und enthält die folgenden Schritte:
- – Stanzen von mindestens zwei Löchern in die Mitte eines Materialstreifens, die sowohl zur Positionierung als auch zum Transport dienen;
- – Stanzen eines ersten Schlitzes zwischen jeweils zwei benachbarten Löchern und eines zweiten sowie eines dritten Schlitzes zwischen erstem Schlitz und linker bzw. rechter Materialstreifenkante, so dass die Löcher von einem sechseckigen Ring umschlossen werden;
- – Schmieden von sechs keilförmigen Ebenen auf dem sechseckigen Ring auf der Unterseite des Materialstreifens;
- – Schmieden von mindestens einer V-förmigen Nut oder einer Kante auf der Oberseite des sechseckigen Rings;
- – Stanzen eines Lochs, dessen Durchmesser größer ist als der Durchmesser des Lochs einer Unterlegscheibe im Zentrum des sechseckigen Rings;
- – Herstellen einer endgültigen Form der Scheibe durch Kaltverformung;
- – Trennung der Scheibe vom Materialstreifen.
- - Punching at least two holes in the middle of a material strip, which serve both for positioning and for transport;
- - Punching a first slot between each two adjacent holes and a second and a third slot between the first slot and the left or right material strip edge, so that the holes are enclosed by a hexagonal ring;
- - Forging six wedge-shaped planes on the hexagonal ring on the underside of the material strip;
- Forging at least one V-shaped groove or edge on top of the hexagonal ring;
- - punching a hole whose diameter is greater than the diameter of the hole of a washer in the center of the hexagonal ring;
- - Making a final shape of the disc by cold deformation;
- - Separation of the disc from the material strip.
