    • The present invention provides a wire feed device for guiding and straightening a wire which is comprised of a wire infeed unit and a self-cleaning deflection head which are connected together by a flexible guide hose. The wire infeed unit has a guide passage therethrough whose inlet and outlet are offset so the wire will remain in contact with a contact element within the passage to generate a signal when the wire is in the passage. The deflection head has a guide arc-shaped guide passage therethrough which, in turn, have outwardly radiating pockets spaced along the outer side thereof which remove debris (e.g. the material abraded from the wire and wire shavings) transport it out of the deflection head. Dimpled guide points are formed on the other side of the arc-shaped guide passage opposite the pockets to facilitate the self-cleaning of the wire. A wire straightening sleeve is positioned downstream of the deflection head, which can generate a control/monitoring signal is positioned downstream of the head.
    • 本发明提供了一种用于引导和矫直线材的送丝装置,该线材由通过柔性导向软管连接在一起的导线单元和自清洁偏转头组成。 导线单元具有穿过其的入口和出口被偏移的引导通道,使得线将保持与通道内的接触元件接触,以在导线处于通道中时产生信号。 偏转头具有穿过其的引导弧形引导通道,其依次具有沿着其外侧间隔开的向外的辐射袋,其移除碎屑(例如,从线和线切屑磨损的材料)将其输出偏转头。 在与凹穴相对的弧形引导通道的另一侧上形成有凹凸的引导点,以便于线的自清洁。 线矫直套筒位于偏转头的下游,可以产生位于头部下游的控制/监测信号。
