摘要
局部加载成形过程中子模具运动变换与控制是低能耗高效局部加载成形的关键。阐明了实现多道次局部加载成形过程的子模具运动与变形和约束功能变换的阀控液压系统工作原理,基于位置控制设计多道次局部加载成形试验样机运动控制系统,构建了10 t变形载荷和2 t约束载荷的双动局部加载成形试验样机,基于CODESYS和C++软件环境开发了具备良好的人机交互性界面的控制软件,开展了2道次局部加载成形试验,试验结果表明构建的硬件平台和开发的软件系统达到了预期的设计要求,为后续大吨位局部加载成形设备控制系统设计与开发提供基础。
The switch and control of motion for sub-dies during local loading forming process are the key to low-energy consumption and high-efficiency local loading forming process.The working principle of valve-controlled hydraulic system of multi-pass local loading forming process was illuminated,which can realize the motion switch and the function switch between deformation and constraint for sub-die.A motion control system of multi-pass local loading forming prototype was designed based on position control.A prototype with 10 t forming load and 2 t constraint load for double-action local loading forming was constructed,and then the control software with a nice human-machine interface was developed based on CODESYS and C++software environment.Two passes local loading forming experiment was carried out.The experimental results indicate that the developed hardware platform and software system meet the expected design requirements,and provide a basis for successive research on the design and development of control system for large tonnage local loading forming equipment.
