Safety servo press control system

Abstract

The invention discloses a safe servo press control system for a press, which includes a servo control unit, a PLC control unit and a power supply control unit; the servo control unit includes a main drive servo controller connected to a three-phase power supply, a water cooler , modulus adjustment motor, electric pump motor and multi-function electric meter, PLC collects the action signal of each corresponding device, and sends out the control signal of controlling corresponding device; Described power supply control unit comprises control transformer, and the front end of control transformer connects AC 380V power supply, controls The back end of the transformer outputs AC 220V voltage, and the back end of the control transformer is connected with a 220V socket, a brake control valve, a photoelectric protection device, a lighting indicator light, and a switching power supply. The present invention improves the working efficiency of the press and makes its work safer , reliable, available in servo presses.

Description

technical field [0001] The invention relates to a press, in particular to a servo press. 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 the normal...

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
