    • A release assembly for wire cutting apparatus. The present invention provides a release assembly for wire cutting apparatus which allows for dynamic alteration of the cut parameters. The release assembly allows for the length of the wire to be cut to be altered, allows for the biasing force to be increased or decreased to thereby reset the release assembly for a wide range of wire gauges, and allows for the stroke length to be altered to thereby either increase or decrease the cut frequency. The release assembly includes a housing having a distal end, a proximal end and a longitudinal chamber. A plunger tube is slidably disposed in the longitudinal chamber and is biased towards the proximal end by a dynamically adjustable spring mechanism. A gauge rod is mounted within the plunger tube at an adjustable axial position. In operation, the wire being pulled from the coil engages the gauge rod and pushes the gauge rod and plunger tube in the distal direction. A sensor senses the distal movement and sends a signal to the cutting mechanism to make a cut in the wire and drop the wire from the cutting machine. The plunger tube is retained in the housing by two collars. The distance between the two collars is dynamically adjustable during cutting operations to adjust the travel distance of the plunger tube. The position of the housing relative to the wire coils is also dynamically adjustable to control the cut length of the wire.
    • 用于线切割装置的释放组件。 本发明提供了一种用于线切割装置的释放组件,其允许动态改变切割参数。 释放组件允许要切割的线的长度被改变,允许偏置力被增加或减小,从而重置用于宽范围的线规的释放组件,并且允许改变行程长度 从而增加或减少切割频率。 释放组件包括具有远端,近端和纵向室的壳体。 柱塞管可滑动地设置在纵向室中,并通过动态调节的弹簧机构朝近端偏压。 在可调节的轴向位置,柱塞管内安装有一个量规杆。 在操作中,从线圈拉出的线接合量规杆并沿远端方向推动量规杆和柱塞管。 传感器感测远端运动,并向切割机构发送信号,以切断电线,并将电线从切割机中掉落。 柱塞管通过两个轴环保持在壳体中。 在切割操作期间两个轴环之间的距离是可动态调整的,以调节柱塞管的行进距离。 壳体相对于线圈的位置也可动态地调节以控制线的切割长度。
