Abstract
A press forming machine having a slide plate which reciprocates by driving sources between a lower support stand and an upper support plate and has a forming space between the lower support stand and the slide plate. In the press forming machine, a reference plate for a displacement reference for the slide plate is supported on the lower support stand. The driving sources are engaged with the slide plate by the drive shafts of the driving sources to drive and press the slide plate. The drive shaft is provided with a through hole axially extending in a shaft center thereof, and displacement measuring devices each for each of the drive shafts measures the displacement of the slide plate portion corresponding to the through hole with respect to the reference plate, through the through hole. As a result, the displacements at the pressurized points on the slide plate can be measured.
