Servo press control system

Abstract

A servo press control system comprises a servo press. The servo press comprises a servo motor, a servo controller, a transmission mechanism, a sliding block, a workbench and a grating ruler, wherein the servo controller is in communication connection with a movement controller through a network, and an I/O interface module, an operation panel and a human-machine interface are connected to the movement controller; the input end of the servo controller is connected with a capacitive energy storage device, and the output end of the servo controller is connected with the servo motor; the servo motor is connected with the transmission mechanism; the sliding block is connected with the transmission mechanism; and the human-machine interface is in communication connection with the movement controller. According to the servo press control system, requirements for different technological curves for movement of the sliding block can be met according to different working conditions, and the torque requirement of the sliding block in a certain position is met; and the stroke of the sliding block can be adjusted according to different workpieces, and the sliding block does not need to move to the top dead center every time in all cycles, so that the cycle time is shortened, meaningless stroke is minimized, and productivity is greatly improved.

Description

technical field [0001] The patent of the present invention belongs to the field of servo control of a press, and in particular relates to a control system of a servo press. Background technique [0002] In recent years, AC servo motor drive has become a new direction for the development of forming equipment. In this context, the servo press that replaces the ordinary asynchronous motor with a servo motor and converts the rotational motion of the motor into a linear motion of the slider through a screw, crank connecting rod, toggle or other mechanisms has made great progress. It can not only maintain the advantages of mechanical drive, but also change the disadvantage of non-adjustable working characteristics, so that the mechanically driven forming equipment has the characteristics of flexibility and intelligence, and the working performance and process adaptability are greatly improved. [0003] The key to the forming technology of the press is the control of the trajector...

Problems solved by technology

However, the high speed, high-precision motion curve planning of the heavy-duty large-inertia system and the capacity of the low-speed high-torque servo motor restrict the development of high-performance servo presses

Therefore, it is very important to develop a high-performance servo press control system. This field has become a research hotspot for presses. Enterprises and research institutions at home and abroad are actively carrying out research on numerical control of presses. Servo press control system products need further improvement
