Technical field
The present invention relates to forging hydraulic machine safety control technology field, particularly relate to a kind of powder hydraulic press force control based on Delta controller.
Background technology
Hydraulic press for powder products automobile engine, electric tool, household electrical appliances, Aero-Space, etc. field produce in, have a wide range of applications, due to very high to pulverulent product parts density uniformity requirement, therefore require that respectively hydraulic cylinder power in floating pressing process is invariable in process of production.
Along with range of application increasingly extensive of hydraulic press for powder products, digital Control Technology have also been obtained and applies widely in hydraulic press for powder products, therefore high-end numerical control hydraulic press for powder products, proposes higher requirement to each hydraulic motion template power of floating.Traditional hydraulic press manually regulation relief valve ensures that power of floating is constant, due to overflow valve opening, close time floating template pressure oscillation can be caused comparatively large, traditional overflow valve power prosecutor formula needs artificial repeatedly re-adjustments, operates very loaded down with trivial details.Have employed Delta controller, servo valve and accumulator control mode for this problem, to realize the constant control of hydraulic cylinder floating power for this reason specially.
Summary of the invention
The technical problem to be solved in the present invention is: improve existing powder hydraulic press press power control procedure of floating, provide a kind of and have the high powder hydraulic press force control based on Delta controller of precision.
The technical scheme that the present invention takes for the technical problem existed in solution known technology is:
Based on a powder hydraulic press force control for Delta controller, described powder hydraulic press force control comprises:
Servo hydraulic cylinder action component, described servo hydraulic cylinder action component comprises a servo hydraulic cylinder, a servo valve and a fuel tank be connected with described servo valve be connected by pipeline road with described servo hydraulic cylinder; Described servo hydraulic cylinder comprises A chamber and B chamber, and described A chamber and B chamber are separately installed with pressure sensor; Servo-cylinder is provided with displacement chi;
