The utility model relates to a double starting control device for the safe operation of a punching machine, which belongs to the control technique of a single chip microcomputer. Including singlechip input and output device. The characteristics of the two touch keys are respectively connected with the input end of the single-chip microcomputer, and connected with the power anode by the resistance, the public termination. The output end of the singlechip and the switch tube is connected with the input end, the input end of the switch tube is connected with the relay coils, motor contactor coil relay normally open contact and controlling punch starting and power supply series. The two touch keys are simultaneously in time, and the single chip microcomputer controls the relay work. The relay is normally opened, and the contacts are closed, so that the motor, contactor coil, power supply, the motor contactor and the starter of the punch motor are controlled to start the punch. At the same time, short on time, control punch operation, long press two touch button in any one, single-chip microcomputer control relay, disconnect contactor coil power supply, punch machine motor loss, turn off the motor. The utility model overcomes the defects that the operation of a single point starting punch is easy to cause accidents.
