Detailed implementation manners

[0024] This part will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the drawings. The role of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present invention. However, it should not be construed as a limitation on the protection scope of the present invention.

[0025] Please refer to Figures 1-5 , the present invention provides a technical solution: a pneumatic punching die, including a workbench 1, a support rod 2 fixedly connected to the surface of the workbench 1, a fixed plate 3 fixedly connected to the end of the support rod 2 away from the workbench 1, a cylinder 4 fixedly connected to the surface of the fixed plate 3, a punching head 5 slidably connected to the inside of the cylinder 4, the surface of the punching head 5 is slidably connected to the inside of the fixed plate 3, a connecting plate 6 is fixedly connected to the end of the punching head 5 away from the fixed plate 3, a sliding rod 7 is slidably connected to the inside of the connecting plate 6, a first spring 12 is movably sleeved on the surface of the sliding rod 7, and both ends of the first spring 12 are fixedly connected to the sliding rod 7 and the connecting plate 6 respectively. One end of the sliding rod 7 below the connecting plate 6 is fixedly connected to a pressing plate 8, a through hole 13 is opened on the surface of the pressing plate 8, and a base 9 is fixedly connected to the surface of the workbench 1.

[0026] When the cylinder 4 drives the punching head 5 to move downward, the punching head 5 moves to push the connecting plate 6. The connecting plate 6 drives the sliding rod 7 and the pressing plate 8 to move. Then, as the connecting plate 6 moves, the pressing plate 8 comes into contact with the stamping part placed on the surface of the base 9. Then, the pressing plate 8 covers the surface of the stamping part, so that the pressing plate 8 presses and fixes the stamping part. The punching head 5 continues to move downward, so that the front end of the punching head 5 passes through the through hole 13 to punch the stamping part pressed by the pressing plate 8. When the punching is completed, the punching head 5 drives the connecting plate 6, the sliding rod 7, and the pressing plate 8 to move upward. Then, the pressing plate 8 no longer presses and fixes the stamping part. Then, when the device punches, the pressing plate 8 moves downward to press and fix the stamping part, and no longer presses the stamping part after the punching is completed, which is convenient for the staff to take it out. At the same time, it avoids fixing it with multiple electric telescopic rods, reducing the production cost of the device.

[0027] The surface of the workbench 1 is fixedly connected to a limit rod 11, and the surface of the limit rod 11 is slidably connected to the inside of the connecting plate 6. Through the setting of the limit rod 11, the connecting plate 6 is limited when it moves downward, thereby avoiding displacement of the connecting plate 6 when it moves downward.

[0028] A connecting rod 14 is fixedly connected to the surface of the connecting plate 6, and a fixed shell 15 is fixedly connected to the end of the connecting rod 14 away from the connecting plate 6. A push plate 16 is rotatably connected inside the fixed shell 15, and the push plate 16 is arranged in an inclined state. A torsion spring 17 is movably sleeved on the rotating shaft surface of the push plate 16, and the two ends of the torsion spring 17 are respectively fixedly connected to the push plate 16 and the fixed shell 15. A fixing rod 18 is fixedly connected to the surface of the workbench 1, and a push rod 19 is slidably connected inside the fixing rod 18. The lower surface of the push rod 19 is arranged in an inclined state, and a spring 20 is fixedly connected inside the fixing rod 18. One end of the spring 20 away from the fixing rod 18 is fixedly connected to the push rod 19. A slide groove 10 is provided on the surface of the base 9, and the inner wall of the slide groove 10 is arranged in an inclined state.

[0029] When the connecting plate 6 moves, the connecting plate 6 drives the connecting rod 14 to move, the connecting rod 14 drives the fixed shell 15 to move, and the fixed shell 15 drives the pushing plate 16 to move, so that the pushing plate 16 contacts the upper surface of the pushing rod 19, so that the pushing plate 16 rotates around the axis, and the pushing plate 16 moves toward the inside of the fixed shell 15. Since the rotation of the pushing plate 16 twists the torsion spring 17, when the pushing plate 16 is no longer in contact with the pushing rod 19, under the torsion of the torsion spring 17, the pushing plate 16 rotates again and is exposed outside the fixed shell 15. When the device completes the stamping of the stamping part, the connecting plate 6 drives the connecting rod 14, the fixed shell 15, and the pushing plate 16 to move upward. At this time, the pushing plate 1 The surface of 6 contacts the lower surface of the push rod 19, so that the push plate 16 is forced to flip over. When the push plate 16 rotates to contact the inner wall of the fixed shell 15, the push plate 16 squeezes the inclined surface of the push rod 19, so that the push rod 19 is forced to move. The push rod 19 moves to push the stamped parts that have been stamped, so that the stamped parts fall into the interior of the slide groove 10. Since the inner wall of the slide groove 10 is arranged in an inclined shape, the stamped parts will slide out through the inclined surface of the slide groove 10, which is convenient for the staff to take out the stamped parts after stamping. At the same time, it is avoided that the staff puts their hands under the equipment to take out the stamped parts after stamping, avoids injuries to the hands of the staff, and protects the staff.

[0030] Working principle: When the cylinder 4 drives the punching head 5 to move downward, the punching head 5 moves to push the connecting plate 6, and the connecting plate 6 drives the slide rod 7 and the pressing plate 8 to move. Then, as the connecting plate 6 moves, the pressing plate 8 comes into contact with the stamping part placed on the surface of the base 9. Thus, the pressing plate 8 covers the surface of the stamping part, enabling the pressing plate 8 to press and fix the stamping part. The punching head 5 continues to move downward, causing the front end of the punching head 5 to pass through the through hole 13 to punch the stamping part pressed by the pressing plate 8. After the punching is completed, the punching head 5 drives the connecting plate 6, the slide rod 7, and the pressing plate 8 to move upward, and then the pressing plate 8 no longer presses and fixes the stamping part.

[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can be made without departing from the gist of the present utility model.
