A mechanical press including a correcting apparatus for the slide bottom dead point position

摘要

A correcting apparatus for slide bottom dead point position of mechanical press which is capable of automatically correcting the slide bottom dead point position rapidly and accurately even during the operation of the mechanical press with the die-height adjusting screw mechanism being fixed.;The correcting apparatus of the present invention comprises a hollow cylindrical member which is disposed between a slide and a die-height adjusting screw mechanism and which can be reverted or contracted along the axis thereof, a bottom dead point position setting means, a bottom dead point position detecting means for detecting a slide bottom dead point position with respect to the slide, contraction force applying means which supply contraction force to the hollow cylindrical member so that the hollow cylindrical member can be reverted or contracted, and correction control means which control the driving of the contraction force applying means to revert or contract the hollow cylindrical member in order to correct the slide bottom dead point position so that a detected bottom dead point position coincides with a set bottom dead point position.
