1. An electromagnetic pulse additive device for a connection ring of a heavy-lift carrier rocket, the device comprising brackets, a 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, wherein the gear disk is rotatably matched with the annular ground rail through a plurality of rolls arranged in a circumferential direction of the gear disk; a top surface of the gear disk is configured to place an annular additive base body; an output shaft of the 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; a first one of the lifting modules is capable of driving a bending module to rise and fall; a second one of the lifting modules is capable of driving an electromagnetic head to rise and fall; a third one of the lifting modules is capable of driving a rotational friction and extrusion module to rise and fall;
an electromagnetic coil is arranged in the electromagnetic head and is electrically connected with a capacitor and a discharge circuit;
the rotational friction and extrusion module comprises a second drive motor and a friction bar fixedly connected to an output shaft of the second drive motor;
the bending module comprises a supporting framework and a supporting plate fixedly arranged on a bottom portion of the supporting framework; the supporting plate is provided with a material guide chute and drive wheels capable of driving an additive thin sheet in the material guide chute to slide with respect to the material guide chute; the supporting plate is further provided with a wedge block, a top block, and a top wheel; the wedge block, the top block, and the top wheel are close to a material outlet end of the material guide chute; a slope of the wedge block and the top block are in close contact with one side of the additive thin sheet; and an other side of the additive thin sheet is in sliding fit with the top wheel.
