Abstract

Gegenstand der Erfindung ist eine Vorrichtung zum Formen von Draht, nämlich eine Schenkelfederwinde- und -biegemaschine. The invention relates to an apparatus for forming of wire, namely a Schenkelfederwinde- and -biegemaschine.

Stand der Technik sind Vorrichtungen mit mehreren Werkzeugen zum Biegen von Draht, der geradlinig zugeführt wird, wobei die Biegewerkzeuge die Drahtbahn umgeben, und Federwickelmaschinen mit einem drehbaren Dorn zum Aufwickeln des Drahtes, wobei die Drahtenden der Feder mittels Biegewerkzeugen geformt werden. State of the art are devices with a plurality of tools for bending wire which is fed in a straight line, the bending tools surrounding the wire path, and spring winding machines with a rotatable mandrel for winding the wire, the wire ends of the spring being shaped by means of bending tools.

Nachteil dieser Vorrichtungen ist deren konstruktive Aufwendigkeit und Beschränktheit auf die Erzeugung bestimmter Federformen. Eine andere Feder erfordert also andere Werkzeuge. The disadvantage of these devices is their constructive complexity and limitation to the production of certain spring shapes. Another spring requires different tools.

Aufgabe der Erfindung ist daher die Verminderung des Aufwands zur Herstellung der Vorrichtung und die Verallgemeinerung der mit denselben Werkzeugen durchführbaren Formgebungen. The object of the invention is therefore to reduce the outlay for producing the device and to generalize the shapes that can be carried out with the same tools.

Lösung dieser Aufgabe ist die Anordnung mehrerer Werkzeuge (86, 88, 90, 92 oder 142; 162, 190, 192) an einem Werkzeughalter (74; 160), der am freien Ende einer dem bekannten Wickeldorn ähnelnden, längsverschiebbaren Welle (12) befestigt ist und ausgewechselt werden kann. Durch Dreh- und Längspositionieren der Welle mittels ihres vom Wickeldorn her bekannten, anders gesteuerten Antriebes läßt sich jedes vorhandene Werkzeug in die Drahtbahn und damit zum Einsatz bringen. Solution of this problem is the assembly of several tools (86, 88, 90, 92 or 142; 162, 190, 192) to a tool holder (74; 160) attached to the resembling at the free end of the known winding mandrel longitudinally movable shaft (12) is and can be replaced. By rotating and longitudinally positioning the shaft by means of its differently controlled drive known from the winding mandrel, any existing tool can be brought into the wire path and thus used.

Vorteil dieser Lösung ist die Vereinfachung des Vorrichtungaufbaus und die Möglichkeit, verschiedene Federformen mittels derselben Werkzeuge zu erzeugen. The advantage of this solution is the simplification of the device structure and the possibility of producing different spring shapes using the same tools.
