Further, the workpiece ejection device 5 and the waste ejection device 6 are both in a modular design, a magnetic switch of a double-acting induction type cylinder is matched with a machine tool mechanism to complete the action, a manipulator of the feeding device 7 is withdrawn, a travel switch sends out a signal, and the signal is linked with a displacement sensor in a female die to enable a machine tool slide block to work.

Furthermore, the feeding device 7 is provided with a travel switch and a manipulator of the feeding device, and the manipulator of the feeding device is controlled by the travel switch, so that the control method accurately controls the work of the whole die and improves the production efficiency.

Further, displacement sensors are mounted on the punching male die 1 and the punching female die 2 in the floating opposite direction punching device, and are used for sensing the position of the workpiece to make corresponding judgment.

Furthermore, a slide way 11 is arranged at the outlet of the workpiece 10 of the workpiece ejection device 5, so that the workpiece can better slide out.

Furthermore, a waste slide 13 is arranged at the outlet of the punching waste 12 of the waste ejection device 6, which is beneficial to discharging the waste.

The working principle of the die is as follows: after the manipulator of the feeding device 7 sends the workpiece into the working area of the die, the manipulator retreats and the travel switch sends out a signal, and the signal is linked with the induction signal of the punching female die 2 to indicate the slide block of the machine tool to start working. And 4, the material pressing plate is contacted with the workpiece and presses the workpiece 10 on the punching female die 1, and the upper and lower positioning pins 3 are inserted into the workpiece positioning holes. The machine tool slide block continues to move downwards, and under the action of the air cushion force of the machine tool, the hole in the upper part of the workpiece is punched out.
