Large hydraulic press crossbeam parallel control system

Abstract

The invention discloses a large hydraulic press crossbeam parallel control system. The large hydraulic press crossbeam parallel control system comprises a hydraulic press crossbeam physical system and an upper computer virtual system which are connected through communication modules. The hydraulic press crossbeam physical system comprises a hydraulic press crossbeam, a plurality of displacement sensors and a plurality of pressure sensors which are arranged at stress concentration positions of the hydraulic press crossbeam, and a PLC; both the displacement sensors and the pressure sensors are connected with the PLC; the upper computer virtual system comprises failure service information and management control information which are directly in communication with and in handshake with the PLC, hydraulic press crossbeam finite element analysis modules are transmitted to hydraulic press crossbeam ideal digital analogy, then the management control information is obtained through a contrastive analysis, and the management control information is in handshake with the PLC through the communication modules. According to the large hydraulic press crossbeam parallel control system, fault emergency monitoring efficiency is improved, and useful empirical data for optimization design of the large hydraulic press in later period, compensation of deflection deformation and the like are provided.

Description

technical field [0001] The invention relates to the technical field of beams of large hydraulic machines, in particular to a parallel control system for beams of large hydraulic machines. Background technique [0002] The traditional large-scale hydraulic press equipment installation method requires large-scale hoisting equipment and sufficient work sites, requires a lot of manpower and high labor intensity, especially when the factory building is low and the floor has been basically completed, it is even more difficult to use the existing lifting equipment. Cannot carry out the installation of large-scale hydraulic machine frame, and construction cost is high. [0003] When a large hydraulic press is installed and used, its top and bottom beams will be severely deformed due to frequent stamping by the compression stamping device, which will reduce the stamping accuracy of the hydraulic press and shorten the overall life of the hydraulic press. Contents of the invention ...
