Apparatus for feeding wire to wire processing machines

摘要

An apparatus for feeding wire to wire-processing machines, in which the wire is drawn off from a pay-off reel holding a wire coil and rotatable about a spindle and fed to a wire feeder upstream of the wire-processing machine, wherein at least one wire-deflecting device, via which the wire drawn off from the pay-off reel is guided and released towards the wire feeder, is connected downstream of the pay-off reel in the wire draw-off direction, and wherein a wire-storage device is provided upstream of the wire feeder, this apparatus presents a guide path, forming a closed circuit, on which the wire runs and the diameter of which can be altered between a smaller value corresponding to an inner radial position of the guide path and a larger value corresponding to an outer radial position of the guide path, wherein the guide path is spring-pretensioned towards the outer radial position.

1. Apparatus for feeding wire to wire-processing machines, the apparatus comprising:
a rotatable pay-off reel holding a wire coil from which the wire is drawn a wire feeder upstream of the wire-processing machine, the wire fed to the wire feeder from the pay-off reel; at least one wire-deflecting device positioned intermediate the pay-off reel and the wire feeder for guiding the wire; a wire-storage device provided in the form of a spring wheel upstream of the wire feeder, said spring wheel defining a circumferential guide path with the wire extending therearound and positioned at a diameter, the diameter of which can be altered between a smaller value corresponding to an inner radial position of the guide path and a larger value corresponding to an outer radial position of the guide path, and being rotatable about a spindle lying perpendicular to a direction of advance of the wire and comprising two circular side parts which act as lateral limiting plates for the wire and being spaced apart from each other by a distance, said side parts defining recesses in radial alignment and uniformly arranged over the circumference of the spring wheel, said recesses receiving a plurality of radially arranged compression springs that define said guide path, said distance between the side parts being smaller than a diameter of each of the compression springs, the diameter of each of the compression springs being defined in a direction parallel to the spindle of the spring wheel, and wherein each compression spring is held in two recesses formed radially in the two side parts.
