Intelligent control method of hydraulic press

Abstract

The invention belongs to the technical field of coil shaping of shell type electric reactors and relates to an intelligent control method and system for an oil press. According to the technical scheme, the system comprises an oil press pressing table (1), a touch screen (2), a control console (3), a PLC (4) and a pressure sensor (5). The touch screen is arranged on the control console, the PLC is arranged in the control console, the oil press pressing table is provided with the pressure sensor, the pressure sensor is connected with the PLC, and the PLC is connected with the touch screen and the control console. The intelligent control system for the oil press improves accuracy and safety of pressure control of the oil press, stage type pressurizing, pressure maintaining and decompressing functions can be achieved in the pressurizing process of the oil press, and the pressing and shaping process of a shell type transformer coil is optimized. The intelligent control system for the oil press has the advantages that pressure control errors are less, the control safety factor is high, the automatic pressurizing, pressure maintaining and decompressing functions can be achieved, various protection functions are complete, and the operation process is safe, convenient, fast and humanized.

Description

technical field [0001] The invention relates to an intelligent control method for a hydraulic press, which can realize the functions of intermittent pressurization, pressure maintenance and pressure relief of a hydraulic press system, and is used for axial compression and shaping of coils in the production of shell-type reactors, belonging to the shell-type reactor coils Plastic technology field. Background technique [0002] Hydraulic presses are used in shaping and pressing processes, for example, in the axial pressing of coils in the production of shell-type reactors. In the background art, 400t hydraulic press equipment is used for axial compression and shaping of the coil in the production of shell-type reactors, thereby improving the tightness and short-circuit resistance of the coil, and reducing the current-carrying wire of the coil in the power frequency alternating magnetic field. vibration, and ensure that the axial size of the coil meets the design and process r...

AI Technical Summary

Problems solved by technology

However, the 400t hydraulic press equipment in the background technology is controlled by electric contacts, pressure gauges, contactors, etc., which has low control accuracy, low safety factor, and does not have automatic functions such as intermittent cycle pressurization, pressure maintenance, and pressure relief.
