Research on Velocity-Displacement Curve for Mechanical Linkage Servo Press

Article Preview

Abstract:

With main transmission system structural form of main servo motor-worm and worm gear commutation reducer-transmission screw-linkage force increasing mechanism, mathematical model of linkage force increasing mechanism is established to obtain the relationships of the velocity and displacement between nut and slide. Velocity and displacement of feature points of slide on the velocity-displacement curve inputted by user transform into which of nut by binary search algorithm and linear interpolation calculation. The feature points of nut transform into the velocity and displacement arrays of points based on S-curve, and then the arrays of points transfer through UDP protocol to lower computer. After the linear fine interpolation by Siemens Simotion D425 motion controller, slide moves according to the setting velocity-displacement curve. The experimental results show that slide moves smoothly, which meets specific technology requirements. The achievements have been successfully applied to a self-developed 2000KN mechanical linkage servo press in a production line of hot forming technology for more than one year, which extends the technology application scope of traditional mechanical press, and improves product quality.
