Abstract
An electromagnetic pulse additive device for a connection ring of a heavy-lift carrier rocket is provided. The device includes brackets, a gear disk rotatably matched with the annular ground rail through a plurality of rolls arranged in a circumferential direction of the gear disk, a first drive motor, an annular ground rail, and a guide rail in a semicircular shape arranged at top ends of the brackets. An output shaft of a first drive motor is fixedly provided with a first drive gear engaged with the gear disk. The guide rail is slidably provided with three lifting modules which respectively drive a bending module, an electromagnetic head arranged electromagnetic coil electrically connected with a capacitor and a discharge circuit, and a rotational friction and extrusion module including a second drive motor and a friction bar fixedly connected to an output shaft of the second drive motor to rise and fall.
