PURPOSE:To stick a laminated press article at welding points arranged on a spiral line for the efficient manufacture of a laminated press article and to improve a press performance without inviting the lowering of the strength of a punch. CONSTITUTION:Reference is made to a laminated press article manufacturing device provided with a punch 1, a die 2 which rotates at a prescribed angle each time linked with the vertical operation of the punch 1, a tubular body 3 for storing press parts which rotates integrally with the die, and a laser beam emitting means 4a, 4b. Beam transmitting holes 9a, 9b are provided, on the side circumferential wall of the tubular body 3 for storing press parts, over the range of a prescribed rotating angle that needs welding; and the welding is performed, between the press parts 7 laminated in the tubular body 3 for storing the press parts, with the laser beam 5a, 5b transmitted through the beam transmitting holes 9a, 9b. |
