The invention relates to a semi-hollow rivet laser shock forming and synchronous riveting method and device, and belongs to the field of laser advanced manufacturing. Pulse laser induced shock force is used for serving deformation drive force, an upper cylindrical female die with the cross section of an annular array structure is selected, and can axially move and rotate around a shaft, a board used for manufacturing of hollow rivets is placed above the upper female die, parts to be riveted are placed below the upper female die, through laser blanking, rivet workblank parts are obtained from the board, and fall on the position above the parts to be riveted, the upper female die axially moves and rotates around the shaft and then staggered from the array structure of the workblank parts, and therefore the workblank parts are pressed above the parts to be riveted; a lower female die is placed below the parts to be riveted, laser shock force is used for carrying out drawing, expansion and other treatment on the workblank parts, the workblank parts gradually form the semi-hollow rivets, and a riveting structure is jointly formed by the rivets and the parts to be riveted.
