<p><P>PROBLEM TO BE SOLVED: To provide a manufacturing device of spring members for reducing variations of a takt time. <P>SOLUTION: A spring member manufacturing device 1 that manufactures the spring member by laser irradiation includes a laser irradiation unit 9 including a plurality of laser irradiation devices that perform predetermined laser irradiation with respect to the spring member 4. The laser irradiation devices are configured so that laser irradiated conditions different from each other are preset for the respective laser irradiation devices, and are arranged so that the respective irradiated positions do not overlap each other. The laser irradiation apparatus is constituted by combining laser irradiation devices having laser irradiation conditions being 2 to the (n-1)th power, n being a positive integer, of predetermined minimum adjustment amount decided in accordance with load adjusting amount required for the spring member. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
