PROBLEM TO BE SOLVED: To provide a press machine the whole length of which can be lowered while sufficiently securing the precision of a press machining. SOLUTION: The outer circumference of an eccentric drum 333 in an eccentric shaft 33 is provided with a rotary ring 34 whose outer circumference is made eccentric to the inner circumference. The outer circumference of the rotary ring 34 is provided with a ring 41 for regulation whose outer circumference is made eccentric to the inner circumference, and the outer circumference of the ring 41 for regulation is fitted with a slide 5. Since the slide 5 and a slide driving apparatus 30 are arranged in such a manner that they are superimposed almost to the same height, the distance from the slide driving apparatus 30 to the lower end of the slide 5 can be shortened, and the whole length of a servo press 1 can be reduced. Further, since the height position of the slide 5 can be finely regulated by rotating the ring 41 for regulation, press working can be performed at a high precision. COPYRIGHT: (C)2006,JPO&NCIPI |
