Abstract:

The rotary forging platform is the most basic implement of large forging hydraulic press, which can upset the heavy disk forgings by the full circle swinging forging process. Then the rotary forging platform of Φ2800 mm with high flexibility, high loading capability and high thermal stress was researched. The key technology of the platform, such as replaceable plate that resisted high-temperature, floating support device with vertical disc spring, compact rotary bearing, and hydraulic power with quick disconnect, solved a series of design problems including large load transfer in the upsetting process, high thermal effect protection of the forge piece, compact full-swing hydraulic drive, portable and quick assembly or disassembly, the electro-mechanical-liquid linkage with high reliability and efficiency, and safety protection, etc. The quick forging press 80 MN with large load and high temperature was applied in production and verified in the engineering practice. Therefore, auxiliary working time was shortened and the work efficiency in the full process of “fast forging” was improved.
