摘要
应用现代变频技术对LW - 7/45 0滑轮式拉丝机进行直进式改造 ,建立系统控制框图和系统控制策略功能图。根据机械速比、拉拔工艺确立合适的速度信号传递方案。实践证明 ,该系统运行稳定、可靠 ,满足了生产工艺的要求 。
By means of modern frequency conversion technology to alter LW-7/450 block wire drawing machine into straight line one. The frame chart and policy function chart of system control are set up. According to mechanical speed ratio and drawing process,the suitable speed signal transfer program is established. It is proved by practice that the function of the system is stable and credible,which satisfies the requirements of production process and has reached the goal of technology alteration.
