The loading device 1 delivers the products one by one to the feeding device 2 in sequence. The feeding device 2 transports the products to different punching devices for punching. The first punching device 3 and the second punching device 4 punch different positions of the product respectively.

[0042] Refer to it again Figure 2 As shown, Figure 2The figure is a schematic diagram of the three-dimensional structure of the feeding device 1 in the embodiment. The feeding device 1 includes a feeding adjustment mechanism 11 and a feeding conveying mechanism 12. The feeding adjustment mechanism 11, the feeding conveying mechanism 12, and the feeding device 2 are arranged in sequence. The feeding conveying mechanism 12 transports the product from the feeding adjustment mechanism 11 to the feeding device 2. The feeding adjustment mechanism 11 includes a feeding adjustment frame 111 and two feeding adjustment members 112. The two feeding adjustment members 112 are movably mounted on the feeding adjustment frame 111. The product is placed between the two feeding adjustment members 112. The movement of the two feeding adjustment members 112 can accommodate pipe products of different sizes, increasing its flexibility and versatility. The loading and conveying mechanism 12 comprises a loading and conveying drive assembly 121 and a loading and conveying assembly 122. The loading and conveying drive assembly 121 drives the loading and conveying assembly 122, which engages with the loading adjustment member 112 and the feeding device 2, respectively. The loading and conveying assembly 122 transports the product from the loading adjustment member 112 to the feeding device 2. In practical applications, the loading and conveying drive assembly 121 includes a motor and a drive chain or belt. The motor's output drives the loading and conveying assembly 122 via the drive chain or belt. The structure of the loading and conveying assembly 122 is compatible with the product, facilitating product transportation.

[0043] Refer to it again Figure 3 As shown, Figure 32 is a schematic diagram of the three-dimensional structure of the feeding device 2 in the embodiment. The feeding device 2 includes a feeding support 21, a transverse feeding mechanism 22, and a longitudinal feeding mechanism 23. The transverse feeding mechanism 22 and the longitudinal feeding mechanism 23 are both mounted on the feeding support 21. The transverse feeding mechanism 22 is engaged with the loading conveyor assembly 122, and the longitudinal feeding mechanism 23 is disposed adjacent to the transverse feeding mechanism 22. The transverse feeding mechanism 22 transports the product transversely, while the longitudinal feeding mechanism 23 pushes the product longitudinally. In specific applications, the transverse feeding mechanism 22 includes a transverse feeding assembly 221, which includes a transverse feeding drive 2211, a transverse feeding guide 2212, and a transverse feeding clamp 2213. The transverse feeding drive 2211 is disposed on the feeding support 21, the transverse feeding guide 2212 is disposed on the feeding support 21, and the transverse feeding clamp 2213 is slidably disposed on the transverse feeding guide 2212. The output end of the transverse feeding drive 2211 is connected to the transverse feeding clamp 2213, and the transverse feeding clamp 2213 clamps the product. Specifically, there are multiple transverse feeding clamps 2213, and the provision of multiple transverse feeding clamps 2213 facilitates uninterrupted product clamping. The transverse feeding clamp 2213 is an existing clamping claw structure. Furthermore, the transverse feeding mechanism 22 also includes a feed fixing assembly 222, which is provided along the direction of the product transport path of the transverse feeding assembly 221, and the feed fixing assembly 222 is arranged side by side with the transverse feeding assembly 221. Specifically, the feed fixing assembly 222 is composed of a plurality of transverse feeding clamps 2213, but the transverse feeding clamps 2213 on the feed fixing assembly 222 are made of soft material to facilitate the horizontal and vertical movement of the product after clamping, while the transverse feeding clamps 2213 of the transverse feeding assembly 221 are made of hard material to prevent micro-movement of the product during transportation.

[0044] The longitudinal feeding mechanism 23 includes a longitudinal feeding drive 231, a longitudinal feeding guide 232, and a longitudinal clamping assembly 233. The output end of the longitudinal feeding drive 231 is connected to the longitudinal clamping assembly 233. The longitudinal feeding guide 232 is longitudinally disposed on the feeding support 21. The longitudinal clamping assembly 233 is slidably disposed on the longitudinal feeding guide 232. After the longitudinal clamping assembly 233 clamps the product, the longitudinal feeding drive 231 drives the longitudinal clamping assembly 233 to move along the longitudinal feeding guide 232. Specifically, the longitudinal clamping assembly 233 includes a clamping block and a clamping member. The clamping block is slidably disposed on the longitudinal feeding guide 232, and the clamping member is disposed on the clamping block. The product is clamped by the clamping member.

[0045] Please refer to Figure 4-Figure 7 As shown, Figure 4 Schematic diagram of the three-dimensional structure of the first punching mechanism 31 in the embodiment; Figure 5Schematic diagram of a portion of the structure of the first punching mechanism 31 in the embodiment; Figure 6 Schematic diagram of the three-dimensional structure of the first mother-and-child needle 3142 in the embodiment; Figure 7This is a cross-sectional view of the first parent-child needle 3142 in the embodiment. The first punching device 3 includes a first punching mechanism 31 and a first drive mechanism 32. The first punching mechanism 31 is located on one side of the transverse feed guide 2212. The first drive mechanism 32 pushes the product on the transverse feed clamp 2213 into the first punching mechanism 31 for punching. The first punching mechanism 31 includes a first punching support assembly 311, a first punching fixing assembly 312, a first punching assembly 313, and a second punching assembly 314. The first punching support assembly 311 is mounted on the feed support 21, the first punching fixing assembly 312 is mounted on the first punching support assembly 311, and the first punching assembly 313 and the second punching assembly 314 are mounted opposite the first punching support assembly 311. The first punching support assembly 311 includes a first punching support member 3111 and a first punching placement member 3112. The first punching support member 3111 is mounted on the feed support member 21, and the first punching placement member 3112 is mounted on the first punching support member 3111. The first punching placement member 3112 is used to place products. The first punching fixing assembly 312 includes a first punching fixing driver 3121 and a first punching fixing member 3122. The first punching fixing driver 3121 is mounted on the first punching support member 3111, and the first punching fixing member 3122 is connected to the output end of the first punching fixing driver 3121. The first punching assembly 313 includes a first punching drive member 3131, a first punching member 3132 and a second punching member 3133. The first punching drive member 3131 is arranged on the first punching support member 3111. The first punching member 3132 is connected to the output end of the first punching drive member. The second punching member 3133 is movably connected to the first punching member 3132. The first punching fixing member 3122 abuts against the second punching member to fix the product. In specific applications, the first punching member 3132 and the second punching member 3133 are connected by a screw, wherein the screw is connected to the second punching member 3133, the screw is movably connected to the first punching member 3132, and a spring is connected between the screw and the second punching member 3133. After the product is placed on the first punching placement member 3112, the first punching fixing member 3122 pushes the second punching member 3133 downward to fix the product. Then, the first punching member 3132 is pressed downward, and the punching needle on the first punching member 3132 punches the product. In this embodiment, in order to fix the product, the side of the second punching member 3133 that contacts the product is adapted to the product. The first punching fixing member 3122 and the second punch are matched by an inclined surface and driven in a variable direction. That is, the first punching fixing member 3122 pushes the second punching member 3133 in the longitudinal direction. Due to the inclined surface, the second punching member 3133 is forced to move downward. The second punching assembly 314 includes a second punching driver 3141 and a first mother-and-child needle 3142 . The output end of the second punching driver 3141 is connected to the first mother-and-child needle 3142 . The first mother-and-child needle 3142 punches the product in a direction opposite to the first punching member 3132 .

[0046] The first mother-and-child needle 3142 includes a first punch needle 31421, a second punch needle 31422 and a reset member 31423. The first punch needle 31421 is connected to the second punching drive member 3141. The second punch needle 31422 is movably arranged on the first punch needle 31421. The reset member 31423 connects the first punch needle 31421 and the second punching drive member 3141, or the reset member 31423 is connected to the first punch needle 31421 and the second punching drive member 3141 at the same time. During specific operation, the outer edge of the first punch needle 31421 breaks through one side of the pipe product and passes through the inside of the pipe product to reach the other side, punching a bulge on the other side. There is another punch needle, which moves in the opposite direction of the first punch needle 31421. The other punch needle gradually approaches the first punch needle 31421 and contacts the second punch needle 31422, pushing the second punch needle 31422 to move relative to the first punch needle 31421. At this time, the second punch needle 31422 compresses the reset part 31423. After the punching is completed, the second punch needle 31422 is reset by the reset part 31423.

[0047] The first punch needle 31421 includes a first punch rod 314213 and a second punch rod 314214. One end of the first punch rod 314213 is connected to the second punch rod 314214, and the second punch rod 314214 is connected to the second punching drive member 3141. In specific applications, the outer diameter of the first punch rod 314213 is smaller than the outer diameter of the second punch rod 314214, that is, after the first punch rod 314213 and the second punch rod 314214 are connected, a step is formed at the connection, which is convenient for limiting the movement of the first punch needle 31421 during use. The first punch rod 314213 has an accommodating cavity 314211, and the second punch rod 314214 has a limiting cavity 314212. The accommodating cavity 314211 is connected to the limiting cavity 314212, and the inner diameter of the limiting cavity 314212 is larger than the inner diameter of the accommodating cavity 314211. Then, the accommodating cavity 314211 and the limiting cavity 314212 are connected to form a stepped hole.

[0048] The second punch 31422 includes a movable rod 314221 and a limit block 314222, one end of the movable rod 314221 is connected to the limit block 314222, and the movable rod 314221 is located in the accommodating cavity 314211, the movable rod 314221 is adapted to the accommodating cavity 314211, so that the movable rod 314221 can move in the accommodating cavity 314211, similarly, the limit block 314222 is located in the limit cavity 314212, the limit block 314222 is adapted to the limit cavity 314212, and the limit block 314222 can move in the limit cavity 314212, the reset member 31423 is also located in the limit cavity 314212, and it is connected to one end of the limit block 314222 away from the movable rod 314221. In specific applications, the outer diameter of the movable rod 314221 is smaller than the outer diameter of the limit block 314222. This can limit the travel of the movable rod 314221 and prevent the entire second punch 31422 from being separated from the first punch 31421. Furthermore, the end of the movable rod 314221 away from the limit block 314222 protrudes from the first punch rod 314213. When the other punch breaks through the tubular product and abuts against the movable rod 314221, it enters the accommodating cavity 314211. At this time, the other punch also brings the waste of the tubular product into the accommodating cavity 314211. When the other punch exits the accommodating cavity 314211, the reset member 31423 pushes the movable rod 314221 to reset, and at the same time, the waste of the tubular product can be completely pushed out of the accommodating cavity 314211.

[0049] Furthermore, the reset member 31423 is an elastic member. In specific applications, the reset member 31423 has greater elasticity, which facilitates the removal of waste pipe products. Therefore, in this embodiment, the reset member 31423 uses a nitrogen spring with greater elasticity.

[0050] During operation, one side of the tubular product is the first mother-and-child needle 3142, and the other side is the other punch needle. The needles on both sides move toward each other. The movable rod 314221 first contacts the tubular product. After encountering the resistance of the tubular product, the assembly retracts into the accommodating cavity 314211. The first punch rod 314213 abuts against the tubular product and breaks through the tubular product. The other punch needle also breaks through the tubular product. When the two are in contact, the other punch needle continues to push the movable rod 314221 to retract into the accommodating cavity 314211 and compress the reset part 31423. After the first punch rod 314213 abuts against the wall of the tubular product on the other side, it pushes up the wall of the tubular product to form a bulge, and then resets. The movable rod 314221 is reset under the action of the reset part 31423. After the reset, the movable rod 314221 ejects the waste produced by punching the other punch needle.

[0051] Through the coordinated arrangement of the first punching needle 31421, the second punching needle 31422, and the reset member 31423, when another punching needle strikes the first punching needle 31421, the other punching needle abuts against the second punching needle 31422 and pushes the second punching needle 31422 to move within the accommodating cavity 314211, compressing the reset member 31423. At this time, the first punching needle 31421, the second punching needle 31422, and the other punching needle can all move simultaneously. After completion, the reset member 31423 resets the second punching needle 31422. This overall structure realizes the synchronous operation of multiple punching needles, eliminating the need for sequential operation, eliminating intermediate waiting time, and improving punching efficiency.

[0052] It should be noted that the other punching needle in this embodiment refers to the punching needle on the first punching member 3132 .

[0053] Furthermore, the first punching mechanism 31 also includes a first punching discharge assembly 315, which has a longitudinal output direction. The first punching discharge assembly 315 includes a first punching discharge driver 3151 and a first punching discharge member 3152. The first punching discharge driver 3151 is disposed on the first punching support member 3111, and the first punching discharge member 3152 is connected to the first punching discharge driver 3151. After the product is punched, the first punching discharge driver 3151 drives the first punching discharge member 3152 to act on the product, pushing the product out of the first punching placement member 3112.

[0054] Please review Figure 3 The first driving mechanism 32 includes a first driving member 321, a first guide member 322 and a first pushing member 323. The first driving member 321 is arranged on the first punching support member 3111, the first guide member 322 is longitudinally arranged on the first punching support member 3111, and the first pushing member 323 is slidably arranged on the first guide member 322. In specific application, the first driving member 321 drives the first pushing member 323 to move on the first guide member 322, and the first pushing member 323 pushes the product on the horizontal feeding clamping member 2213 into the first punching placement member 3112.

[0055] Please refer to Figure 8 As shown, Figure 8The figure is a schematic diagram of the three-dimensional structure of the second punching device 4 in the embodiment. The second punching device 4 includes a second punching mechanism 41, a third punching mechanism 42, and a punching discharge mechanism 43. The second and third punching mechanisms 41, 42 punch different sides of the product respectively. After punching, the punching discharge mechanism 43 ejects the product. The second punching mechanism 41 includes a second punching support assembly 411, a third punching assembly 412, and a fourth punching assembly 413. The second punching support assembly 411 includes a second punching support member 4111 and a second punching placement member 4112. The second punching support member 4111 is mounted on the feed support member 21, and the second punching placement member 4112 is mounted on the second punching support member 4111. The product is placed on the second punching placement member 4112. The third punching assembly 412 includes a third punching drive 4121, a punching drive connecting member 4122, a second punching fixing member 4123 and a third punching member 4124. The third punching drive 4121 is arranged on the second punching support assembly 411. The punching drive connecting member 4122 connects the second punching fixing member 4123, the third punching member 4124 and the third punching drive 4121. The third punching drive 4121 pushes the punching drive connecting member 4122 to move. The punching drive connecting member 4122 pushes the second punching fixing member 4123 and the third punching member 4124 to move in the longitudinal direction. The second punching fixing member 4123 fixes the product, and the punching needle on the third punching member 4124 punches the product. In specific applications, the punching drive connecting member 4122 and the second punching fixing member and the third punching member 4124 are all connected by an inclined surface. When the punching drive connecting member 4122 moves downward, the inclined surface pushes the second punching fixing member and the third punching member 4124 to move longitudinally.

[0056] The fourth punching assembly 413 includes a fourth punching driver 4131 and a fourth punching member 4132. The fourth punching driver 4131 is arranged on the second punching support 4111. The fourth punching member 4132 is connected to the fourth punching driver 4131. The fourth punching driver 4131 pushes the fourth punching member 4132 to punch the product.
