[0040] In the embodiments of the present invention, please refer to Figure 1 and Figure 10 The protective guide unit 5 includes: a protective frame 53, a buffer pad 54, an anti-impact column 55, a buffer protection seat 56 and a collection box 57. The protective frame 53 is arranged outside the discharge port 12 and is fixedly connected to the mounting support frame 1. A buffer pad 54 is provided between the protective frame 53 and the mounting support frame 1. The top of the buffer pad 54 is rotatably connected to the protective frame 53. The buffer pad 54 is also rotatably connected to the anti-impact column 55. The other end of the anti-impact column 55 is slidably connected to the buffer protection seat 56.

[0041] In this embodiment, the buffer pad 54 includes a pad and a rubber pad fixedly connected to the surface of the pad. During discharge, the workpiece ejected from the inner side of the mold base 23 is discharged from the discharge port 12 and falls on the buffer pad 54.

[0042] In the punching device for machining, the servo motor 15 drives the threaded rod 16 to rotate, and the threaded rod 16 can cooperate with the switching seat 14 to drive the processing table 13 to move. The processing table 13 will drive the mold seats 23 at the top of both ends to move synchronously. When the mold seat 23 on one side moves to just below the punching seat 4, the mold seat 23 on the other side enters the inner side of the adjacent discharge port 12. When the processing table 13 drives the mold seat 23 to move just below the punching seat 4, the induction push plate 42 will contact the inclined side of the trapezoidal push control seat 37. As the processing table 13 continues to move, the trapezoidal push control seat 37 drives the induction push plate 42 to move toward the side close to the concave gas seat 39. The induction push plate 42 drives the second piston to move inside the drive control tube 40, driving the concave gas seat 39 to move inside. The air on the side enters the inner side of the piston tube 46, and the sensing piston 47 moves upward. The sensing piston 47 cooperates with the support column 48 and the movable rod 49 to drive the control seat 50 to move upward. The control seat 50 drives the cooperative clamping plates 45 on both sides to move relative to each other through the push-pull rod 51. The limiting clamping plate 43 cooperates with the spring connected to the mold seat 23 to initially limit the workpiece, and the cooperative clamping plate 45 can limit the workpiece again, thereby completing the positioning of the workpiece. The hydraulic expander 3 drives the stamping seat 4 to move downward to complete the stamping of the workpiece. After the stamping is completed, the threaded rod 16 can cooperate with the switching seat 14 to drive the processing table 13 to move, so that the mold seat 23 originally located directly below the stamping seat 4 enters the inner side of the discharge port 12 on the other side, and the mold seat originally located at the discharge port 1 2 moves to the bottom of the punching seat 4. During the movement, the workpiece to be processed is placed on the inside of the die seat 23. When the die seat 23 enters the inside of the discharge port 12, the cooperative clamping plate 45 will release the restriction on the workpiece inside the die seat 23. The flip rack 24 abuts against the fixed point touch plate 11. As the processing table 13 continues to move, the fixed point touch plate 11 cooperates with the mounting support frame 1 to drive the flip rack 24 to move along the guide rail 25. The flip rack 24 cooperates with the flip gear 19 to realize the rotation of the connecting rod 18, driving the die seat 23 to flip to the side away from the processing table 13. During the flipping process, the side support frame 20 will drive the pressure sensing control tube 26 to flip synchronously, and the flexible rope 28 is located inside the pressure sensing control tube 26. The sensing slide bar 27 on the side is pulled, and as the pressure energy sensing control tube 26 is flipped, the sensing piston 30 can be moved inside the pressure energy sensing control tube 26, driving the air inside the pressure energy sensing control tube 26 along the transmission control guide tube 29 into the inside of the energy transmission cavity 32, and the air inside the energy transmission cavity 32 enters the inside of the jacking tube 33 along the energy guiding tube 31, driving the first piston to move upward, and the first piston cooperates with the first push rod to drive the jacking base 36 to move upward, and ejects the workpiece located inside the mold base 23. The ejected workpiece is discharged from the discharge port 12 and falls on the buffer pad 54. The buffer spring arranged between the anti-impact column 55 and the buffer seat 56 can absorb the impact force. The workpiece after buffering falls into the inside of the collection box 57, completing the recovery and storage of the workpiece.When the reset pull rod 21 and the support slide rod 22 cooperate with the reset spring to drive the die base 23 to flip toward the processing table 13, the flexible rope 28 releases the pull on the sensor control slide rod 27, the sensor control piston 30 resets, and the lifting base 36 also resets, placing the workpiece to be stamped inside the die base 23, thereby achieving continuous stamping.

It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
