Bidirectional synchronous loading hydraulic forming equipment for aero-engine sealing ring

Abstract

The invention discloses bidirectional synchronous loading hydraulic forming equipment for an aero-engine sealing ring. The bidirectional synchronous loading hydraulic forming equipment comprises an automatic die filling system, a main machine system, an ultrahigh pressure system and a numerical control system, wherein the main machine system comprises two servo hydraulic cylinders of which the displacement synchronous control precision can reach + / -0.02 mm, and a die locking hydraulic cylinder; the ultrahigh pressure system not only drives the hydraulic cylinder, but also provides a bulging pressure of 100MPa at most; the pressure can be dynamically adjusted along with feeding displacement of the servo hydraulic cylinders, so that the requirement for bidirectional synchronous loading hydraulic forming of special-shaped section members made of difficult-to-deform materials such as high-temperature alloy is met; and the numerical control system is based on a control mode of an upper computer and a lower computer and has intelligent functions such as database and parameter analysis. According to the bidirectional synchronous loading hydraulic forming equipment, closed-loop control isadopted, and the functions of precise load application, servo drive / hydraulic constant-load composite control, load / pressure real-time detection, forming error intelligent compensation and the like are integrated, so that integration and automation of the bidirectional loading bulging process are achieved, and product quality consistency and stability are guaranteed.
