Zusammenfassung:The utility model discloses an automatic tension control mechanism for a wire cutting machine, which can convert the tension of an electrode wire into the tensile force applied to a wire guide wheel and transmit the tensile force to a pressure-bearing area of a weighing sensor through a connecting block, the pressure-bearing area deforms after being stressed, and the weighing sensor is used for weighing the electrode wire. A processor in the sensor can convert deformation into an electric signal to be output, the driving assembly can adjust the moving track of the sliding block according to the electric signal, then tensioning or loosening of the electrode wire is achieved, and automatic control over tension is achieved. 本实用新型公开了一种用于线切割机的张力自动控制机构,该张力自动控制机构,可将电极丝的张力转化为导丝轮受到的拉力并通过连接块将该拉力传递至称重传感器的承压区,该承压区受力后产生变形,传感器内部的处理器能够将变形量转化为电信号输出,驱动组件可根据该电信号调整滑块的移动轨迹,进而实现电极丝的张紧或松开,实现张力的自动控制。
