DEVICE FOR MULTICORE SPRINGS MANUFACTURING Russian patent published in 2017 - IPC B21F35/00 B21F7/00 

FIELD: machine engineering.

SUBSTANCE: device contains wire accumulators, wire winding unit, spring winding mandrel, rotation mechanisms for the mandrel and the wire winding unit. The corresponding wire supply units with individual drives are located between the wire accumulators and the wire winding unit. The wire accumulators, the wire supply unit and the wire winding unit are arranged in series. The wire accumulators and one end of the wire supply unit are rigidly connected to the first support ring, and the second end of the wire supply unit and the connecting flange of the wire winding unit are rigidly connected to the second support ring. The support rings are rotatably mounted in support posts and at least one of them is provided with rotation mechanism. The wire accumulators are made with the possibility for eliminating unintentional unwinding of the wire. The wire supply unit is configured for tensioning the wire before it is fed to the wire winding unit and for controlling the amount of this tension.

EFFECT: increase serviceability of the produced multicore springs and stability of their operating parameters, control tension level of wires and thereof adjustment possibility.
