Vorrichtung zur Herstellung von verseilten Drähten und Maschine zur Herstellung von konzentrisch verseilten Drähten

摘要

A twisted wire manufacturing apparatus is provided with cradle (6) which is suspended at a pair of rotating shafts (3,4) having extreme ends opposed to each other through bearings. A main body (1) of the wire twisting machine is mounted on the cradle (6). A raw material guide and a twisted wire guide (53) are mounted in respect to a pair of rotating shafts (3,4) having axial insertion holes. The raw material drawing machine and the twisted wire take-up machine are mounted on the cradle (6). The raw wire material is guided through these devices. Another twisted wire manufacturing machine has a plurality of injection dies (25) communicating with an annular groove formed in the rotary head. An annular shoe for gradually reducing a sectional area of the annular groove (24) is slidably fitted to the annular groove. The raw material is supplied into the annular groove and the raw wires are injected from the injection dies (25). One injection die of a plurality of injection dies is provided with means for increasing an injection resistance of the raw wires. An injection speed of the core raw wire injected from one injection die is made slower than that of outer layer raw wires injected from other injection dies.
