In order to control, in a wire shaping apparatus with a rotatable wire intake device ( ), friction of the wire at the bore wall of a wire holder ( ) which finally leads the wire towards the shaping station, and in order to reduce it to zero if necessary, it is suggested to provide said apparatus, the wire holder ( ) of which can be rotated programmably controlled about the wire axis, with a remote controllable wire brake device ( ) which acts radially upon the wire being fed along, and the wire brake device is programmably controlled.

Apparatus for shaping wire into wire products

In order to control, in a wire shaping apparatus with a rotatable wire intake device (10), friction of the wire at the bore wall of a wire holder (52) which finally leads the wire towards the shaping station, and in order to reduce it to zero if necessary, it is suggested to provide said apparatus, the wire holder (52) of which can be rotated programmably controlled about the wire axis, with a remote controllable wire brake device (114) which acts radially upon the wire being fed along, and the wire brake device is programmably controlled.

The invention relates to a wire shaping device. State of the art: DE 39 15 784 C1 discloses a wire shaping device comprising a program controlled rotating and displacing head which carries shaping tools and on to which moves the wire arriving from a stationary wire intake device. DE 22 64 589 C3 discloses, in the context of a spiral spring winding machine, a device for simultaneously taking in and twisting the incoming wire for producing an initial tension in the spring body. One disadvantage of the known wire shaping device is the relatively limited shapes of wire which can be produced. It is an object of this invention to improve the known wire shaping device for the purpose of increasing the range of finished shapes of the wire structures. The solution to this problem lies in a combination of the known twisting device with the known wire shaping device so that the wire intake device is rotatable about the axis of the wire and is program controlled, optionally also in its direction of feed (backwards as well as forwards). The advantage of this solution is the additional degree of freedom of the wire movement, which increases the shaping possibilities.
