ABSTRACT:
In a die interchanging operation for a press which includes steps of used-die-demounting, bolster driving and new-die-mounting, an automatic die-interchanging control system comprises a judging circuit for outputting a signal if no unfinished steps exist before the last finished step among those which have finished their operations and a control unit for resuming the operation from a step immediately subsequent to the last finished step in response to the output from the judging circuit, whereby the die interchanging operation can be started from any step of the operation.
The automatic die-interchanging control system further comprises a lamp lighting control circuit together with indication lamps, which enables to inform an operator of the current situation of the die interchanging operation.
