<P>PROBLEM TO BE SOLVED: To provide a press machine which has a mechanism to reduce pressurization force unevenness or vibration becoming a problem particularly when a precise load control is necessary and which uses a servo motor as a power source. <P>SOLUTION: The press machine having a punch 2, a die 4 and blank holder die 7 comprises a press machine slide 3 which is interlocked to the die 4, a first power transmission mechanism 6a which can freely drive the die 4 and the press machine slide 3 by a plurality of supporting means 21, and has an impact buffer mechanism 8a, a first servo motor 5a which drives the press machine slide 3 via the first power transmission mechanism 6a, a second power transmission mechanism 6b which can freely drive the blank holder die 7 via a plurality of the supporting means 22 and has an impact buffer mechanism 8b, and a second servo motor 5b which drives the blank holder die 7 via the second power transmission mechanism 6b. <P>COPYRIGHT: (C)2007,JPO&INPIT |
