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.

Press forming apparatus and press forming method for a semi-solid metal material

Provided is a press forming method for a semi-solid metal material, including: manufacturing a semi-solid metal material in a container having an upward opening by injecting molten metal into the container, and cooling the molten metal while stirring the molten metal; inverting the container and storing the semi-solid metal material in a temporary storage space; discharging a liquid phase part from the semi-solid metal material through the inverting; and pressing the semi-solid metal material by feeding the semi-solid metal material, from which the liquid phase part is discharged, into dies of a pressing machine.

Press forming method for a semi-solid metal material and press forming system for a semi-solid metal material

A work feed method and apparatus for feeding workpieces to and from the die of a press comprises a feed rack having a workpiece clamping device thereon is disposed within the press gap and reciprocates horizontally between positions where it picks up pieces from a supply stage at the die and transfers them simultaneously to the die and discharge stages. The feed bar is operated by a drive unit driven by an electric motor and having a rocking arm mechanism connected to the feed bar to reciprocate the latter horizontally and a slide mechanism at each end of the feed bar to reciprocate the feed bar vertically which is operated by a camming mechanism through a ball crank device which is operated by a lift rod driven through a camming mechanism by the drive motor.
