A die cushion controlling apparatus for controlling an operation of a
cushion pad, which comprises a pad drive mechanism for driving to raise
or lower the cushion pad while applying an upward energizing force, a
load measuring unit for measuring a load generated in the cushion pad, a
time detecting unit for detecting a generating time and a vanishing time
of the load, and a control unit for controlling the pad drive mechanism
so that a load measured value measured by the load measuring unit follows
a preset load pattern during a period from when the time detecting unit
detects the generating time of the load until when the time detecting
unit detects the vanishing time of the load.
