Description

Verfahren zur Herstellung von dauerfesten Schraubenfedern Es ist bekannt, daß man durch Oberflächendrücken die Dauerhaltbarkeit von Federn ganz wesentlich steigern kann. Bei Schraubenfedern, bei denen man mit Hilfe von Roll-oder Hämmerwerkzeugen nicht genügend an alle Stellen herankommen kann, hilft man sich in der Weise, daß man nach der Fertigstellung der Feder die oberflächliche Schicht mit Hilfe des Stahlkugelgebdäses bearbeitet. Aber auch das Bearbeiten mit dem Stahlkugelgebläse ist in diesem Fall sehr mangelhaft, weil die oberflächlichen Schichten zwischen den Windungen überhaupt nicht bestrahlt werden können. Die Steigerung der Dauerhaltbarkeit, die man durch Oberflächendrücken bei. Schraubenfedern erzielen kann, ist deshalb verringert.Process for the production of durable coil springs It is known that by surface pressure the durability of springs is essential can increase. In the case of coil springs, where one can use rolling or hammering tools cannot get enough to all places, one helps oneself in such a way that after the completion of the spring, the superficial layer with the help of the Stahlkugelgebdäseses processed. But also machining with the steel ball blower is in this case very poor, because the superficial layers between the turns at all cannot be irradiated. The increase in durability that you get through Surface pressures at. Can achieve coil springs is therefore reduced.

Nach der Erfindung kann man die gesamte oberflächliche Schicht , Oberflächendrücken, wenn man das Verfahren vor der Wicklung am fertigen, geradegerichteten Draht durchführt. Man bekommt auf diese Weise eine viel gleichmäßigere Drückwirkung bei Schraubenfedern als beim Kugelblasen, weil (las Drücken des Drahtes sowohl innen und außen "als auch zwischen den Windungen wirkt.According to the invention, the entire superficial layer, surface pressures, if the procedure is carried out on the finished, straightened wire before winding. In this way you get a much more even pressure effect with coil springs than with ball blowing, because (read pressing the wire both inside and outside "as also acts between the turns.

Das Oberflächendrücken von Draht im ausgestreckten Zustand, z. B. mittels Ziehens durch eine Düse, ist an sich bereits bekannt.The surface pressing of wire in the extended state, e.g. B. by drawing through a nozzle is already known per se.

Das Verfahren kann nur bei Schraubenfedern angewendet werden, die aus gehärtetem Stahldraht gewickelt werden: Bei Schraubenfedern, die erst nach der Wicklung, gehärtet werden, ist das neue Verfahren dagegen nicht verwendbar.The method can only be used for coil springs that are wound from hardened steel wire: In the case of coil springs that are only wound after the In contrast, the new process cannot be used for winding, hardened.
