[0034] Below, combined with the attached Figure 1 To the attached Figure 6 As well as specific implementation methods, the present invention is further described. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0035] like Figures 1-6 As shown, the present invention provides a hollow tube 1 circle buckle chain production device. The straight hollow tube 1 is transformed into an interlocking chain through the automated processing of the device. The structure includes a coiling device 2, a cutting device 3, a forming device 4 and a welding device 5.

[0036] Specifically, in this embodiment, the cross section of the hollow tube 1 is rectangular, that is, the hollow tube 1 is a rectangular strip before processing. The above-mentioned devices are all arranged on a workbench 6, and the coiling device 2 is arranged at the left end of the workbench 6. The coiling device 2 includes a coiling drive mechanism 21 and a center rod 22. The coiling drive mechanism 21 drives the center rod 22 to rotate, and the straight hollow tube 1 is transported toward the center rod 22 through the conveying device 7. As the center rod 22 rotates, the hollow tube 1 becomes spirally wound around the center rod 22, and the hollow tube 1 around the center rod 22 rotates synchronously with the center rod 22; there are many options for the conveying device 7, and a conveyor belt or other methods can be used. In this embodiment, a plurality of pulleys 71 are used, and a transmission channel is provided between the pulleys 71 for conveying the hollow tube. The core tube 1, the coil driving mechanism 21 device includes a coil motor 211 and a support frame 212. The support frame 212 is a rectangular long block. The support frame 212 is provided with a rotating bearing hole 213 for the hollow rod to pass through. The front end of the center rod 22 passes through the rotating bearing hole 213 and cooperates with the coil motor 211 to rotate and drive the center rod 22, so that the center rod 22 rotates horizontally on the support frame 212. The middle and rear ends of the center rod 22 are both on the outside of the support frame 212. Among them, the rear end end of the center rod 22 is provided with a card slot 221, which is stuck with the front end of the hollow tube 1 between the hollow tube 1 and the center rod 22 before it surrounds the center rod 22, so as to avoid sliding between the hollow tube 1 and the center rod 22, resulting in the hollow tube 1 being unable to wrap around the center rod 22. When the winding work is performed, try to make the hollow rod and the long strip of hollow rod 22 close together. There is a certain inclination angle between the core tubes 1, so that a spiral hollow tube 1 is generated during winding. The pitch between the spiral hollow tubes 1 can be controlled by controlling the rotation speed of the center rod 22 and the conveying speed of the conveying device 7. When the spiral position of the hollow tube 1 is in the middle position of the center rod 22, the active speed of the center rod 22 and the conveying speed of the conveying device 7 are controlled, so that the spiral length of the hollow tube 1 and the center rod 22 are in a stable state, and then the cutting device 3 cuts the end of the spiral hollow tube 1. The cutting device 3 cuts the hollow tube 1 in units of one spiral of the hollow tube 1 around the center tube. Specifically, the cutting device 3 includes a cutting knife 31 and a cutting lifting device 32. The cutting direction of the cutting knife 31 is consistent with the direction of the hollow tube 1. The central axis extends in the same direction. The cutting device 3 is arranged above the rear end of the central rod 22. When cutting is required, the cutting lifting device 32 lowers the cutting knife 31 and cuts the hollow tube 1 from just above the axis of the central rod 22 until the annular hollow tube 1 at the end is cut off. The cut portion is a ring with an open spiral shape, which requires a forming device 4 to process it into a standard ring shape. Specifically, the forming device 4 includes a clamping device 41, a clamping and rotating device 42 and an extrusion device 43. The extrusion device 43 is used to extrude and deform the cut hollow tube 1 into a circular ring shape. The open ring before forming is not on the same plane, but its shape already has a ring shape. The extrusion device 43 only needs to squeeze the opening onto a plane.A ring-shaped hollow tube 1 can be obtained. There are many types of extrusion devices 43 that can achieve this action, so they are not described in detail here. The clamping device 41 is used to clamp the circular hollow tube 1, and the clamping and rotating device 42 is used to rotate the clamping device 41 to change the angle between the circular hollow tube 1 and the spiral hollow tube 1, so that the middle of the circular hollow tube 1 is located in the rotation path of the end of the spiral hollow tube 1, that is, the annular opening of the circular hollow tube 1 is perpendicular to the axial extension direction of the center rod 22, and the height of the hollow tube 1 is the same as the height of the center rod 22. When the spiral hollow tube 1 rotates, The front end of the spiral hollow tube 1 will penetrate into the annular hollow tube 1. After the spiral hollow tube 1 rotates one more circle, the annular hollow tube 1 has been loosely buckled with the end of the spiral hollow tube 1. The cutting device 3 cuts the end of the spiral hollow tube 1, and the refueling device extrude and deforms the cut hollow tube 1 to achieve the buckling between the two annular hollow tubes 1. The welding device 5 uses a laser welding device 5, which is arranged on one side of the end of the center rod 22. When the clamping device 41 clamps the annular hollow tube 1, the crack part of the annular hollow tube 1 is welded. After the hollow tube 1 is rolled into a spiral shape by the coiling device 2, the hollow tube 1 is squeezed into a ring shape by molding, which facilitates the insertion of the rotating hollow tube 1 at the back, thereby completing the interlacing and buckling. The entire production process does not require human intervention and can be realized as unmanned operation and automated continuous operation. The manufacturing speed can be increased by ten times, dozens of times or even higher than the existing technology. If this technical solution can be promoted and applied, its economic value and social benefits will be huge and it will be highly competitive in the market.

[0037] In some embodiments, in order to prevent the cutting device 3 from cutting too much when cutting the spiral hollow tube 1, resulting in the hollow tube 1 being cut into multiple sections, the coiling device 2 is further provided with an expansion device 23, the expansion device 23 including an expansion channel member 231, the expansion channel member 231 being a block fixed on the workbench 6, the expansion channel member 231 being provided on the rotation path of the hollow tube 1, the expansion channel member 231 being provided between the middle and end portions of the center rod 22, the expansion channel member 231 being provided with a spiral channel 222 for the hollow tube 1 to pass through, the spiral channel 222 is used to increase the pitch between the spiral hollow tubes 1. The middle part of the spiral channel 222 is a hollow part for the center rod 22 to pass through. The inner wall of the spiral channel 222 is a groove channel extending in a spiral shape. When the center rod 22 drives the hollow tube 1 to rotate, the hollow tube 1 will rotate forward along the groove channel. Therefore, the shape of the hollow tube 1 after passing through the groove channel changes to the shape of the groove channel. Increasing the distance between each circle of the groove channels can increase the pitch of the spiral hollow tube 1. In this way, when cutting one of the rings, the possibility of cutting other parts of the knife 31 can be greatly reduced.

[0038] On the basis of adding an expansion device 23, in some embodiments, since a certain friction force will inevitably be generated between the hollow tube 1 and the groove channel, only the friction force between the hollow tube 1 and the center rod 22 is relied upon to drive the hollow tube 1 to rotate and move forward around the center tube. Because the friction force between the hollow tube 1 and the groove channel is too large, the hollow tube 1 does not rotate, so an auxiliary rotation device 8 is added. The auxiliary rotation device 8 includes an auxiliary frame 81, a clamping rotation mechanism 82, a first transmission mechanism 83 and a second transmission mechanism 84. The winding motor 211 drives the first transmission mechanism 83 and the second transmission mechanism 84 to rotate synchronously. The first transmission drives the hollow rod to rotate, and the second transmission mechanism 84 drives the clamping rotation mechanism 82 to rotate. The clamping rotation mechanism 82 is clamped and cooperated with the outer side of the spiral hollow tube 1, and the clamping rotation mechanism 82 is rotatably arranged on the auxiliary frame 81.

[0039] In some embodiments, the clamping device 41 includes a clamping drive 411 and two clamping heads 412. Driven by the clamping drive 411, the clamping heads 412 clamp and cooperate with the annular hollow tube 1. The inner side surface of the clamping heads 412 is semicircular.

[0040] In some embodiments, the squeezing device 43 includes an active pressing device 431 and a supporting device 432. The supporting device 432 includes a blocking member 4321 and a horizontal displacement device 4322 for moving the blocking member 4321. The blocking member 4321 is provided at the end of the center rod 22. The blocking member 4321 abuts and cooperates with one side of the hollow tube 1, and the active pressing device 431 abuts and cooperates with the other side of the hollow tube 1. Specifically, the active pressing device 431 includes a pressing plate 4311 and a pressing drive device 4312. The pressing drive device 4312 is used to drive the pressing plate 4311 to move horizontally.

[0041] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and replacements made by technicians in this field on the basis of the present invention fall within the scope of protection required by the present invention.
