Die cushion controlling apparatus and die cushion controlling method |
摘要 |
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.
