[0009] As a preferred embodiment of the application, the threaded rod and the driving motor are connected through threads, the threaded rod is internally connected with the driving motor, an electromagnet is fixedly connected in the electromagnetic pressure head, and a roller motor is arranged in the driving wheel.

[0012] As a preferred embodiment of the present application, the central processing unit sends the received positioning signal to the controller cluster unit, the controller cluster unit controls the driving motor to slide on the threaded rod to drive the limiting rod to move, and after the limiting rod moves to the set position, the controller cluster unit feeds back a positioning completion signal to the central processing unit. The control input unit generates a mold moving signal and sends it to the central processing unit.

[0013] As a preferred embodiment of the present application, after receiving the positioning completion signal, the central processing unit sends a mold moving signal to the controller cluster unit. After receiving the mold moving signal, the controller cluster unit controls the roller motor to move to drive the sliding block and the positioning platform to move.

[0019] The working process of the plastic water port punching machine based on intelligent control comprises the following steps:

[0020] One: place the lower punching die above the positioning platform and position the lower punching die through the positioning pin, then place the workpiece to be punched and the punching cutter on the lower punching die, and then input the positioning signal to make the controller cluster unit control the limiting rod to move to the set position;

[0021] Two: input the die moving signal again, and after the central processing unit receives the positioning completion signal and the die moving signal, the controller cluster unit controls the sliding block to move to contact with the limiting rod, and then controls the telescopic rod to punch downward, the sensor detection unit records the pressure at the front end of the telescopic rod during the punching operation, and sends the recorded information to the memory processing unit, and after the punching is completed, the controller cluster unit controls the telescopic rod to attract the punching cutter on the die through the electromagnet, and pushes the positioning platform out again to facilitate taking out the punched workpiece;

[0022] Three: input the repeated punching signal again and place the workpiece to be punched on the positioning platform again, then input the die moving signal, and the plastic water port punching machine control system automatically punches and returns the material to realize the cycle of placing the workpiece, inputting the die moving signal, automatic punching and material returning.
