Abstract:
The present disclosure provides a device for super cryogenic forming of a metal thin-walled curved surface part, including a super cryogenic medium conveying and pressurizing unit, a press, a die unit and a control system. A blank holder cylinder, a blank holder slide, a deep drawing cylinder and a deep drawing slide are disposed on the press. The die unit includes a male die, a blank holder and a female die. The super cryogenic medium conveying and pressurizing unit includes an autoboosting cryogenic container. A cryogenic channel in the blank holder, a cryogenic channel in the female die and a cavity of the female die are communicated with an outlet of the autoboosting cryogenic container by cryogenic pipes, respectively. A cryogenic pump is disposed on the cryogenic pipe between the cavity of the female die and the autoboosting cryogenic container.
