PURPOSE:To quicken a two-dimensional or three-dimensional change of a press machine by rocking the lever for clamping of one part for two-dimensional use or three dimensional use by changing the angle of the lever for both clamping against the cam integrally provided on a rotary shaft. CONSTITUTION:In case of changing over from a two dimensional transfer feeding state to three dimensional state, a connection rod 7 is returned to the original place by actuating the hydraulic cylinder 5 of an angle adjusting means 10. The lever 106 for three dimensional lift is rotated in counter clockwise direction by rotating the lever 106 for three dimensional clamp in clockwise direction by an air cylinder 126. The change can therefore be made to three- dimensional transfer state. A multidimensional transfer mechanism 130 can move feed bars 131, 132 in the opposite direction by the clamp shaft 38 of a clamping and unclamping driving mechanism 125. In this way, the direction can quickly be changed with a simple structure and the machine efficiency in pressing can be increased.
