分析了影响张力恒定的因素,设计了恒张力控制装置。我国生产的线切割机床大多采用高速走丝,其张力无法进行调节与控制,影响工件的加工精度和表面质量。本文论述高速走丝系统保持丝张力恒定的一种装置。
The factors affecting the constant tension are analyzed and a constant tension control device is designed. China’s production of wire-cutting machine tools are mostly used high-speed wire, the tension can not be adjusted and control, affecting the machining accuracy and surface quality of the workpiece. This article discusses a high-speed wire feeding system to maintain a constant filament tension device.
