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type cylinder is matched with a machine tool mechanism to complete the action, a manipulator of the feeding device 7 is withdrawn, a travel switch sends out a signal, and the signal is linked with a displacement sensor in a female die to enable a machine tool slide block to work.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.

The workpiece 10 ejection device comprises a double-action induction type cylinder and an ejector rod. The stroke of the work piece 10 ejection double-action induction type cylinder is controlled by a magnetic switch. After the punching male die 1 completely exits the workpiece 10, a machine tool slide block travel switch sends a signal, a workpiece arranged on the punching female die 2 is ejected out to reciprocate an induction type cylinder to start working, the workpiece 10 is ejected out of the punching female die 2, and the workpiece 10 is ejected out and enters a slide way and flows into a workpiece collecting box through the slide way 11. The waste ejection device 6 comprises a double-action induction type cylinder and an ejector rod. The waste ejection double-action induction type cylinder adopts a magnetic switch to control the stroke. When the workpiece 10 is ejected, the punching waste 12 in the punching female die 2 is ejected out by the punching waste 12 ejection double-action induction type cylinder arranged at the other side of the punching female die 2; the punched scrap 12 is ejected into a scrap chute 13 and flows through the chute into a scrap receptacle. After the work of the workpiece 10 and the punching waste 12 ejected out of the cylinder is finished, the magnetic switch of the double-acting induction type cylinder sends a signal, the feeding device 7 starts feeding again, and the next automatic punching work cycle is carried out.
