    • PURPOSE:To remove a used wire easily by a method wherein a waste wire winding reel drum of a wire cut electric discharge machine is divided into a plurality of components and the diameter of the drum is made variable. CONSTITUTION:A wire electrode used for wire cut electric discharge machining is wound around a winding reel 18. The drum 42 of the winding reel 18 is divided into a plurality of drum components 50 and each of the components 50 is pulled by a pull spring 56 in such a direction that the diameter may take the minimum. When the wire winding reel 18 is fixed to a winding motor 40, the diameter of the drum component 50 is expanded by the taper spindle 62 of the winding motor 40 against the pull spring 56 so that the drum takes the maximum diameter. Under this state, the waste wire is wound. When the widning reel 18 is removed after the winding operation is completed each component 50 of the drum 42 is pulled by the spring 56 to diminish the diameter. Thus, the used wire can be removed easily from the reel 18.
    • 目的:通过将线切割放电加工机的废线卷绕卷筒分割为多个部件并使滚筒的直径可变的方法,容易地除去二手丝。 构成:用于线切割放电加工的线电极缠绕在卷绕卷轴18上。卷绕卷轴18的滚筒42被分成多个滚筒部件50,并且每个部件50被拉簧56拉动 在直径可以采取最小的方向。 当卷绕卷轴18固定在卷绕马达40上时,滚筒部件50的直径通过卷绕马达40的锥形主轴62相对于拉簧56而扩大,使滚筒成为最大直径。 在这种状态下,废线缠绕。 当卷绕操作完成之后移除卷绕卷轴18时,滚筒42的每个部件50被弹簧56拉动以减小直径。 因此,可以容易地从卷轴18去除所使用的线。

    • PURPOSE:To make the tension of a wire electrode maintain constant for the purpose of improving the machining accuracy by decreasing the torque of a torque motor giving torque to a wire bobbin with decreasing of the diameter of the turn of the wire electrode of the wire bobbin. CONSTITUTION:As a wire electrode is delivered from a wire bobbin, the diameter of wire turn decreases. This decreasing amount is detected by a non-contact type and optical fiber type displacement sensor 13 and is entered in a control unit 14. The control unit 14 determines the torque of a torque motor 12 by the input signals of the displacement sensor 13 having been previously measured and stored as tension and the related table of input voltage of the torque motor 12 to so control the torque motor 12 as to decrease the torque. By this constitution, the total tension of the wire electrode can be maintained constant and the machining accuracy can be improved.
    • 目的:为了使线电极的张力保持恒定,以提高加工精度,通过减小转矩电机的转矩,通过线芯的线电极的转弯直径减小而向线轴提供转矩 。 构成:由线芯电线从电线绕线筒输送,导线直径减小。 该减小量由非接触型和光纤型位移传感器13检测并进入控制单元14.控制单元14通过位移传感器13的输入信号确定转矩电动机12的转矩 先前测量并存储为张力和扭矩电动机12的输入电压的相关表,以便控制转矩电动机12以减小转矩。 通过这种结构,能够使线电极的总张力保持恒定,能够提高加工精度。

    • PURPOSE:To suppress damage to a work to a minimum limit when a metallic wire is disconnected, by holding the tension of drawing the mtallic wire at constant. CONSTITUTION:A tension roller 6 is rotated in the reverse direction to rotation of a bobbin 14 according to its drawing motion of a metallic wire 13 through a torque motor preset to the torque corresponding to drawing tension of the metallic wire 13. Under this condition, if wire-cut work is started with the metallic wire and a work as electric discharge electrodes while continuously drawing the metallic wire 13, the metallic wire 13 is drawn with constant tension determined by slipping force with the periphery of the tension roller 6. In this way, damage to the work or the like at disconnection of the metallic wire can be suppressed to a minimum limit.
    • 目的:通过将金属丝拉伸的张力保持在一定程度,当金属丝断开时,将工件的损坏抑制在最小限度。 构成:张紧辊6根据金属丝13的拉伸运动沿与线轴14的旋转相反的方向旋转,转矩马达预先设定为与金属丝13的拉伸张力相对应的转矩。在这种条件下, 如果在连续地拉伸金属丝13的同时用金属线和作为放电电极的工件开始线切割工作,则金属线13以与张力辊6的周边的滑动力确定的恒定张力拉伸。在此 可以将金属线断开时的作业等的损坏抑制在最小限度。
