| 摘要: |
| 针对冷政薄钢板生产的特点,设计了冷轧薄钢板专用闪光焊机的总体结构。分析了冷轧薄钢板专用闪光焊机控制系统,包括冷轧薄钢板闪光焊机动夹具送进速度的控制,动夹具位置的控制以及顶锻控制。动夹具送进速度控制曲线由动夹具送进速度分量函数、灵敏度分量函数和焊接电流分量函数构成。动夹具位置的控制是根据不同的闪光模式,计算出动夹具的位移函数,借助动夹具的位移函数来控制动夹具的运动位置。通过控制焊接时动夹具位置来实现顶锻过程。 |

| Abstract: |
| According to characteristics of thin strip cold rolling product line, the total configuration and control system of special flash butt welding machine in thin strip cold rolling was designed. The control system includes running-in speed control of movable clamp, position control of movable damp and upset control. Control of running-in speed of moveable clamp consists of velocity function, sensitivity function and welding current function.According to the different flash mode, moveable clamp position function can be calculated.Position of moveable clamp is controlled by position function of moveable clamp.Upset phase is controlled by position of moveable clamp in the welding. |
