Abstract

See full text

Provided is a press forming apparatus for a semi-solid metal material, including: a slide caused to make a reciprocating linear motion; a sub-slide mounted so as to be movable relatively to the slide; a fluid pressure mechanism interposed between the slide and the sub-slide, which is capable of moving the sub-slide relatively to the slide by fluid pressure; an upper die mounted to the sub-slide; and a lower die. The press forming apparatus is configured to press-form the material while applying predetermined pressure to the material for a predetermined period by bringing, along with descent action of the slide, the upper die into contact with the material fed into the lower die, then stopping the slide at a predetermined position, and moving the upper die mounted to the sub-slide relatively to the slide by the fluid pressure mechanism under a state in which the slide is stopped.
