Abstract

Beschrieben und dargestellt ist ein Verfahren und eine Anlage zur Herstellung von bikonischem Draht, d. h. von Draht mit sich wiederholenden zylindrischen Drahtabschnitten einerseits und konischen Drahtabschnitten andererseits, aus zylindrischem Ausgangsmaterial, insbesondere zur Herstellung von Schraubendruckfedern.A method and a system for producing are described and illustrated biconical wire, d. H. of wire with repeating cylindrical wire sections on the one hand and conical wire sections on the other hand, made of cylindrical Starting material, in particular for the manufacture of helical compression springs.

Erfindungsgemäß wird kostengünstig ein qualitativ hochwertiger bikonischer Draht dadurch hergestellt, daß die konischen Drahtabschnitte durch eine Warmformgebung realisiert werden. Die dargestellte Anlage besteht folglich funktionsnotwendig aus einer Erwärmungseinheit (1) und einer Formgebungseinheit (2). Im Ausführungbeispiel sind noch realisiert eine Abkühleinheit (3) hinter der Erwärmungseinheit (1), eine Abkühleinheit (4) hinter der Formgebungseinheit (2), eine Walzensteuerung (5), eine Nachwalzeinheit (6) hinter der Formgebungseinheit (2), eine weitere Erwärmungseinheit (7) zum Anlassen, eine der weiteren Erwärmungseinheit (7) nachgeordnete Abkühleinheit (8), ein Abcoiler (9), ein Rollenrichtapparat (10) und ein Aufcoiler (11).

Figure 00000001
According to the invention, a high-quality, biconical wire is produced inexpensively in that the conical wire sections are realized by hot shaping. The system shown consequently consists of a heating unit (1) and a shaping unit (2). In the exemplary embodiment, a cooling unit (3) behind the heating unit (1), a cooling unit (4) behind the shaping unit (2), a roller control (5), a re-rolling unit (6) behind the shaping unit (2) and a further heating unit are also implemented (7) for starting, a cooling unit (8) arranged downstream of the further heating unit (7), a decoiler (9), a roller straightening apparatus (10) and a recoiler (11).
