[0026] When the metal tube punching die is working and the metal tube is processed, the opening and closing degree of the partition 18 arranged at the lower part of the rectangular through hole 17 is adjusted, and then the thread groove 14 on the outside of the material box shell 13 and the thread column 12 on the column 11 are adjusted up and down, so that the metal tube can flow inside the material box 1; after the debugging is completed, the metal tube is put into the material box 1 from the outside of the material box shell 13, so that the metal tube contacts the bottom plate 15, and a motor is arranged inside the material box, and the motor drives the eccentric disk at the lower end of the slider 16 to rotate, so that the rectangular block at the top of the slider 16 moves back and forth left and right, and the metal on the bottom plate 15 is moved back and forth. The tube is pushed to the outlet of the partition 18 at the lower end of the rectangular through hole 17, and the partition 18 is fixed with a pin through the positioning hole 131 to prevent the partition 18 from being displaced. Then the placed metal tube is pushed with the electric push rod 132 to push the metal tube out. When the next batch of metal tubes with different apertures from the previous batch is to be processed, the above working process is repeated to adjust the outlet size of the metal tube discharge on the feed box 1, so that the same feed box can be used to process metal tubes with different apertures, thereby solving the problem of replacement of the feed box and manpower loss, and realizing the processing of metal tubes of different sizes.

[0027] As a specific embodiment of the present invention, a lathe 2 is arranged below the partition 18, and the lathe 2 includes a slide groove interface 21, a roller 22, a vibration plate 23 and a waste belt 24. The right end face of the lathe 2 is provided with a slide groove interface 21, a roller 22 is provided at the top right end of the lathe 2, a vibration plate 23 is provided at the left end of the roller 22, and a waste belt 24 is provided below the vibration plate 23 and inside the lathe 2.

[0028] When the metal tube comes out from the outlet below the partition 18, it falls on the lathe 2 below and is processed. After the processing is completed, the metal tube is vibrated by the vibration plate 23, and the vibration plate 23 separates the finished product and the waste. The separated finished product and the waste pass through the roller 22 together, and the waste falls from the gap of the roller 22 to the waste belt 24 below. The roller 22 continues to rotate to transport the finished product to the chute interface 21, and the waste is continuously transported to another chute interface 21 through the waste belt. The finished product and the waste are collected separately using a collection box, thereby avoiding the work of manual selection.

[0029] As a specific embodiment of the present invention, a cutting unit 3, a punching unit 4 and a drilling unit 5 are respectively designed above the lathe 2, the cutting unit 3 is arranged on the left side of the blanking box 1, the punching unit 4 is arranged on the left side of the cutting unit 3, and the drilling unit 5 is located on the left side of the punching unit 4.

[0030] When the metal tube placed on the lathe 2 passes through the cutting unit 3, the cutting unit 3 is used to cut the metal tube. By adjusting the driving speed of the cutting unit 3, the cutting length of the metal tube can be adjusted, so that the cutting unit 3 can cut the metal tube according to production needs. The metal tube after cutting is clamped to the stamping unit 4 by a robot arm, and the metal tube is stamped to complete the processing technology. When encountering a circular hole with high hardness and a simple processing shape, the drilling unit 5 can be used to drill the metal tube. Using a robot arm to clamp the metal tube for drilling can reduce the use of additional machines.

[0031] As a specific embodiment of the present invention, the cutting unit 3 includes a cutting shell 31, an adjustable clamp 6, a supporting platform 32 and a cutting blade 33. The lower end of the outer portion of the cutting shell 31 is provided with a fixedly connected adjustable clamp 6, the supporting platform 32 is provided directly below the adjustable clamp 6, and the cutting blade 33 is provided directly above the adjustable clamp 6.

[0032] When the metal tube passes through the cutting unit 3, the metal tube is placed on the supporting table 32 to facilitate the cutting of the metal tube. The metal tube placed on the supporting table 32 is fixed with an adjustable clamp 6 to prevent the metal tube from moving due to force during the cutting process, which may cause the finished product of the cutting metal tube to fail and increase unnecessary losses. After the metal tube placed on the supporting table 32 is fixed, the cutting blades 33 are driven to cut the metal tube. After the cutting is completed, the next metal tube cutting is carried out to complete the metal tube cutting process.

[0033] As a specific embodiment of the present invention, the adjustable clamp 6 includes a movable chuck 61, a chuck rack 62, an opening adjustment gear 63, a displacement rack 64 and a displacement adjustment gear 65, the chuck rack 62 is fixedly connected to the movable chuck 61, a square hole 631 is provided in the center of the opening adjustment gear 63, the displacement adjustment gear 65 is arranged on the back side of the opening adjustment gear 63, and the displacement rack 64 is fixedly connected to the lower part of the movable chuck 61.

[0034] When the metal tube below the cutting unit 3 is fixed, the square hole 631 in the center of the opening adjustment gear 65 is rotated, and the chuck rack 62 fixedly connected to the movable chuck 61 is meshed and driven, so that the movable chuck 61 is displaced, and then the opening of the adjustable clamp 6 is adjusted, so that the adjustable clamp 6 can be adjusted according to the size of the metal tube, so as to better fix the metal tube, and at the same time, the relative displacement of the displacement adjustment gear 65 and the displacement rack 64 is adjusted, and the transmission gear eccentric cylinder 661 is connected to the gear displacement adjustment gear eccentric cylinder 651, and the transmission gear 66 is driven. The connecting rod connecting the transmission gear eccentric cylinder 661 and the gear displacement adjustment gear eccentric cylinder 651 utilizes the inertia force of the connecting rod and the movement path of the transmission gear eccentric cylinder 661 is only half of the gear displacement adjustment gear eccentric cylinder 651, so as to realize the back and forth movement of the displacement adjustment gear 65 and the meshing displacement rack 64, so as to realize the clamping and loosening of the metal tube under the cutting unit 3. When the next batch of metal tubes with different apertures from the previous batch are to be processed, the above working process is repeated to realize the clamping and loosening of different metal tubes by the adjustable clamp 6, thereby increasing the working efficiency.

[0035] As a specific implementation of the present invention, a punching platform 41 is arranged below the punching unit 4 . The punching platform 41 uses a pressure memory metal, and a movable inner sleeve 42 is designed inside the punching platform 41 .

[0036] After the robot arm clamps the metal tube and passes through the stamping unit 4, the stamping unit 4 is used for stamping. A stamping table 41 made of pressure memory metal is used to place the metal tube, which can better fix the metal tube and prevent it from moving left and right. A movable inner sleeve 42 is arranged inside the stamping table. When the metal tube is perforated and stamped, the punching knife can be prevented from damaging the stamping table 42, and waste can also be discharged from the internal outlet.

[0037] As a specific implementation of the present invention, a cooling pipe 51 is arranged beside the drilling unit 5 , and a cleaning brush 52 is designed below the drilling unit 5 .

[0038] When the drilling unit 5 is used to process the metal pipe, after the processing time increases, the drill bit's working efficiency will decrease due to the long working time. Using the cooling tube 51 to cool the drill bit can delay the drill bit from stopping working. After processing a large number of metal pipes, a large amount of waste will accumulate under the drill bit, seriously affecting the working process. The waste cleaning brush 52 is provided to avoid manual cleaning, which increases the working time.

[0039] Working principle: After measuring the aperture of the metal tube, adjust the feed box 1 to the appropriate size for the flow of the metal tube, put the metal tube into the feed box 1, first use the cutting unit 3 to cut the metal tube, after cutting, use the mechanical arm to clamp the metal tube and enter the stamping unit 4 for stamping. If the metal tube has a high processing intensity and a circular processing shape, the drilling unit 5 can be used for processing. After the metal tube is processed, the finished product and waste are separated by the machine tool 2 and then collected.

[0040] In order to make the description concise, not all possible combinations of the various technical features in the above embodiments are described. However, as long as the combination of these technical features does not exist, the above embodiments only express several implementation methods of the present invention. The description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
