DETAILED DESCRIPTION

[0028] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Example 1

[0030] A preferred embodiment of the pneumatic punching and cutting tool provided by the utility model is as follows: Figures 1 to 5 As shown: a pneumatic punching and cutting tool, including a base 1, a support column 2 is fixedly connected to the top of the base 1, a processing table 3 is fixedly connected to the top of the support column 2, a first electric push rod 4 is fixedly connected to the back of the processing table 3, an output end of the first electric push rod 4 is fixedly connected to a first slider 5 slidably connected to the processing table 3, a second electric push rod 6 is fixedly connected to the left side of the first slider 5, an output end of the second electric push rod 6 is fixedly connected to a second slider 7 slidably connected to the first slider 5, and a threaded rod 8 is rotatably connected to the top of the second slider 7. The surface of the threaded rod 8 is threadedly connected to a mounting plate 9, and both sides of the mounting plate 9 are slidably connected to limit rods 10 fixedly connected to the second slider 7, the bottom of the mounting plate 9 is fixedly connected to a first cylinder 11, and the bottom of the first cylinder 11 is fixedly connected to a punch 12, and one side of the punch 12 is provided with a support plate 15 that fits the processing table 3, the internal thread of the support plate 15 is connected to a screw 16 embedded in the processing table 3, the bottom of the support plate 15 is fixedly connected to a second cylinder 17, and the output end of the second cylinder 17 is fixedly connected to a cutting knife 18.

[0031] In this embodiment, the base 1 and the top of the first slider 5 are provided with mutually intersecting vertical sliding grooves, and the second slider 7 forms an X-axis and Y-axis sliding structure through the first electric push rod 4 and the second electric push rod 6, so as to adjust the position of the punch 12 in all directions and improve its flexibility when used.

[0032] In this embodiment, the limiting rod 10 and the second slider 7 are perpendicular to each other, and the threaded rod 8 drives the mounting plate 9 to form a lifting structure along the limiting rod 10. The limiting rod 10 can limit the movement of the mounting plate 9 so that it can be lifted vertically.

[0033] In this embodiment, the midpoints of the punch 12 and the cutting knife 18 are located on the same straight line, and the support plate 15 is detachable through the screws 16. When the cutting function is not needed, the support plate 15 can be removed by unscrewing the screws 16, and the cutting knife 18 can be removed.

[0034] In this embodiment, the interior of the punch 12 is hollow in design, and the fan 13 can be turned on to allow the wind to be blown out from the interior of the air guide 14, thereby achieving the purpose of blowing out the rubber embedded in the punch 12.

[0035] In this embodiment, the support columns 2 are rubber columns, and the support columns 2 are arranged at equal intervals laterally at the bottom of the processing table 3. The support columns 2 made of rubber material can play a certain buffering role and reduce the shaking amplitude of the processing table 3.

[0036] Example 2

[0037] On the basis of Example 1, a preferred embodiment of a pneumatic punching and cutting tool provided by the utility model is as follows: Figures 1 to 5 As shown: a fan 13 is fixedly connected to the top of the mounting plate 9, an air duct 14 extending into the interior of the punch 12 is fixedly connected to the left side of the fan 13, a push block 19 is slidably connected to the left side of the processing table 3, a cleaning brush 20 fitted to the processing table 3 is fixedly connected to the tail of the push block 19, two groups of buffer plates 21 are rotatably connected to the bottom of the processing table 3, the surfaces of the two groups of buffer plates 21 are rotatably connected to extrusion plates 22 slidably connected to the base 1, and the sides of the two groups of extrusion plates 22 are fixedly connected to shock-absorbing dampers 23 fixedly connected to the base 1.

[0038] In this embodiment, the cleaning brush 20 is parallel to the top of the processing table 3. The cleaning brush 20 forms a sliding structure through the push block 19. The push block 19 can be moved to drive the cleaning brush 20 to slide on the top of the processing table 3. Through the sliding of the cleaning brush 20, the debris or dust on the processing table 3 can be cleaned.

[0039] In this embodiment, the two groups of buffer plates 21 are both arranged at an angle, and the connection point between the two groups of buffer plates 21 and the processing table 3 is located at the top end point of the two groups of buffer plates 21. When the processing table 3 is subjected to impact force, a thrust is applied to the buffer plate 21, so that the buffer plate 21 rotates sideways around the connection point with the processing table 3, and applies a thrust to the extrusion plate 22 during movement.

[0040] In this embodiment, the extrusion plate 22 forms a sliding structure along the top of the processing table 3 through the buffer plate 21, and the shock-absorbing damper 23 forms a telescopic structure through the extrusion plate 22. The extrusion plate 22 transmits force to the shock-absorbing damper 23, and the shock-absorbing damper 23 converts the thrust, thereby reducing the amplitude of the equipment shaking.

[0041] The working principle and use process of the utility model are as follows: first, the rubber to be punched is placed under the punch 12, and then the first cylinder 11 is opened to control the punch 12 to descend, and the rubber is punched. After the punching is completed, the rubber can be taken under the cutting knife 18, and then the second cylinder 17 is opened to drive the cutting knife 18 to descend. The cutting knife 18 can cut the rubber at this time. When the cutting function is not needed, the support plate 15 can be disassembled by unscrewing the screw 16, and the cutting knife 18 can be disassembled. When the punch 12 is punching, in order to prevent the rubber from being embedded in the inside of the punch 12, the fan 13 can be turned on to blow the wind out from the inside of the air duct 14, so as to achieve the purpose of blowing out the rubber embedded in the punch 12. By setting the first electric push rod 4, when it pushes the first slider 5, the X-axis displacement of the punch 12 can be controlled. When the second electric push rod 6 controls the sliding of the second slider 7, the Y-axis displacement of the punch 12 can be controlled. By rotating the threaded rod 8, the height of the punch 12 can be controlled to be adjusted, so as to achieve the Z-axis adjustment of the punch 12.

[0042] After the rubber processing is completed, it is necessary to clean the processing table 3. The push block 19 can be moved to drive the cleaning brush 20 to slide on the top of the processing table 3. The debris or dust on the processing table 3 can be cleaned by the sliding of the cleaning brush 20. By setting the buffer plate 21, it is inevitable that shaking will occur when the punch 12 is punching. When the processing table 3 is subjected to impact force, a thrust will be applied to the buffer plate 21, so that the buffer plate 21 rotates sideways around the connection point with the processing table 3, and during movement, a thrust is applied to the extrusion plate 22, so that the extrusion plate 22 transmits the force to the shock absorbing damper 23, and the shock absorbing damper 23 converts the thrust, so as to reduce the amplitude of the equipment shaking.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
