A control system and control method for an intelligent servo press

Abstract

The invention discloses a control system for an intelligent-type servo press, and the system comprises a servo drive unit, a PLC control unit, and a control power unit. The servo drive unit comprises a main drive servo controller, a mold adjustment servo controller, an electric pump motor, and a multifunction power meter, wherein the main drive servo controller, the mold adjustment servo controller, the electric pump motor and the multifunction power meter are connected to a three-phase power supply. The PLC control unit comprises a PLC, and a drive power end of the PLC is connected with an AC 220V power supply. A control power end of the PLC is connected with a DC 24V power supply, and the PLC collects the operation signals of all corresponding devices, and transmits the control signals for controlling the corresponding devices. The control power unit comprises a control transformer, wherein the front end of the control transformer is connected with an AC 380V power supply, and the rear end of the control transformer outputs an AC 220V voltage serving as the AC 220V power supply. The system guarantees the punching precision of the press and the quality of a punched part, improves the punching efficiency, and can be used in the control of the press.

Description

technical field [0001] The invention relates to a press, in particular to a press control system. Background technique [0002] In the stamping process of sheet metal, the precision of the workpiece is not only affected by the stamping process and stamping die, but also affected by factors such as the mechanical structure of the press, material properties, slider guidance, cooling and lubrication, and control methods such as rigidity and heat. The influence of stability and other comprehensive performance of the press. The accuracy of the bottom dead center of the slider of the press is a direct reflection of the comprehensive performance of the press. [0003] In the stamping process, it is often affected by the stamping speed and working temperature, which causes a large drift of the bottom dead center of the slider, which leads to a great reduction in the precision of the stamping parts, and even damages the machine tool equipment and working molds. In order to ensure t...

Problems solved by technology

[0003] In the stamping process, it is often affected by the stamping speed and working temperature, which will cause a large drift of the bottom dead center of the slider, which will greatly reduce the precision of the stamping parts, and even damage the machine tool equipment and working molds.

In order to ensure the normal progress of the stamping process, it is necessary to stop the machine from time to time to detect the displacement of the bottom dead point of the slider, and manually adjust the position of the bottom dead point of the slider, which greatly affects the production efficiency and processing quality
