[0002] Composite pipes are widely used in modern construction. For example, they can be applied in fields such as building engineering, oil and gas technology, automotive industry, energy engineering, and machinery manufacturing.

[0003] In different fields, the processing requirements for composite pipes vary due to different needs. For example, in composite pipes, the welding quality of the inner and outer pipes is crucial to the performance and reliability of the final product. Poor weld appearance and uneven welding are common quality problems, typically manifesting as uneven weld surfaces, weld beads, undercut, incomplete penetration, lack of fusion, porosity, and slag inclusions. These problems not only affect the aesthetics of the welded joint but may also lead to insufficient weld strength, reduced corrosion resistance, and shortened service life.

[0004] Therefore, it is necessary to improve the existing technology to overcome the aforementioned defects. Summary of the Invention

[0005] In view of the above, the present application provides embodiments to solve at least one problem existing in the background art. The purpose of this application is achieved through the following technical solution: a composite pipe flaring system, wherein the composite pipe includes an outer pipe and an inner pipe located inside the outer pipe, and the flaring system includes:

[0006] Frame;

[0007] The clamping and moving assembly includes several sets of clamping structures arranged in pairs on the frame, with clamping space between each pair of clamping structures to clamp the composite tube;

[0008] A flaring assembly is disposed on one side of the clamping and moving assembly, including a first driving member and a flaring member connected to the first driving member. The flaring member can follow the first driving member to move toward the direction close to the composite tube, so that the end of the inner tube is turned outward to form a flanged port.

[0009] A rotating component, disposed on one side of the flaring component, is used to drive the composite tube to rotate;

[0010] A welding assembly is disposed near the rotating assembly, the welding assembly being configured to weld the flanged port in the composite tube to the end of the outer tube during rotation.

[0011] In one embodiment, the flaring member includes a mounting portion and a flaring structure connected to the mounting portion, the mounting portion being connected to the first driving member;

[0012] The flared structure is conical, and the first preset diameter of the flared structure is larger than the diameter of the composite pipe.

[0013] In one embodiment, the flared part is detachably connected to the first driving member;

[0014] Furthermore, the first driving member can drive the flared member to move along the first direction.

[0015] In one embodiment, the rotating assembly includes a second drive member mounted on the frame and a transmission rod connected to the second drive member and arranged in pairs. The composite tube can be placed on the two transmission rods, and the second drive member drives the transmission rods to rotate so as to drive the composite tube to rotate.

[0016] In one embodiment, the flaring system further includes a positioning component disposed on one side of the flaring assembly, the positioning component being capable of fitting the flanged port to the end of the outer tube.

[0017] In one embodiment, the positioning component includes a third drive member and a positioning member connected to the third drive member, the third drive member being capable of driving the positioning member to move in a first direction.

[0018] In one embodiment, the positioning component further includes a fourth drive member and a pressure plate connected to the fourth drive member, the fourth drive member being capable of driving the pressure plate to move along a second direction to fix the composite tube in the second direction.

[0019] In one embodiment, each of the holding structures includes a fifth drive member and a holding baffle connected to the fifth drive member, the two holding baffles being configured to support the composite tube and move along the second direction following the fifth drive member.

[0020] In one embodiment, the welding assembly includes a laser welder.

[0021] In one embodiment, the flaring system further includes a detection component for detecting the position of the composite tube.

[0022] Compared with the prior art, this application has the following beneficial effects: By setting a frame and a flaring assembly set on the frame, a rotating assembly set on one side of the flaring assembly, and a welding assembly set close to the rotating assembly, the first driving component in the flaring assembly can drive the flaring component to move precisely toward the composite tube, so as to realize that the end of the inner tube in the composite tube is turned outward to form a uniform and consistent flange port, ensuring the flaring quality and consistency, and greatly improving the work efficiency for subsequent welding of the inner tube and the outer tube; in addition, the rotating assembly can drive the composite tube to rotate, so that the welding assembly can weld the flange port of the rotating composite tube to the outer tube, ensuring that the weld is heated evenly during the welding process, which can effectively improve the welding strength and stability, and avoid the defects that may be caused by manual welding.

[0031] To fully understand this application, detailed steps and structures will be presented in the following description to illustrate the technical solution of this application. Preferred embodiments of this application are described in detail below; however, in addition to these detailed descriptions, this application may have other implementation methods.

[0032] like Figure 1 and Figure 3 As shown, this application provides a composite pipe flaring system. In this embodiment, the composite pipe includes an outer pipe and an inner pipe located inside the outer pipe. In some implementations, it is necessary to connect and fix the inner pipe and the outer pipe.

[0033] In this embodiment, the composite tube flaring system includes a frame 1, a clamping and moving component 2, a flaring component 3 disposed on one side of the clamping and moving component 2, a rotating component 4 disposed on one side of the flaring component 3, a welding component 6 disposed near the rotating component 4, and a control component. The clamping and moving component 2 clamps and moves the composite tube in a second direction, allowing the composite tube to reach a fixed position where the flaring component 3 performs the flaring process. The flared composite tube is then transferred to the rotating component 4, causing the rotating component 4 to drive the composite tube to rotate. The welding component 6 on one side welds the composite tube during rotation, resulting in a uniform and stable connection. It should be noted that in this embodiment, the control component is connected to the clamping and moving component 2, the flaring component 3, the rotating component 4, and the welding component 6 via signal or electrical connections, enabling each component to execute corresponding actions according to the instructions of the control component. Furthermore, the execution instructions of the control component in this embodiment are all common and mature technologies, which will not be elaborated upon here. The welding component 6 mentioned above includes a laser welder.

[0034] In an alternative embodiment, reference Figure 4 As shown, the flaring assembly 3 includes a first driving member 31 and a flaring member 32 connected to the first driving member 31. The flaring member 32 can follow the first driving member 31 and move in a first direction toward the composite tube, so that the end of the inner tube is turned outward to form a flanged port. In this embodiment, the first driving member 31 is a hydraulic cylinder.

[0035] Understandably, the flaring system also includes a first limiting member, and the flaring component 3 is defined as being located at the front end of the composite tube, while the first limiting member is located at the rear end of the composite tube. When the composite tube is flared, the first limiting member abuts against the rear end of the composite tube, and the first driving member 31 drives the flaring member 32 to press against the front end of the composite tube.

[0036] It is understood that in this embodiment, the first limiting member is detachably connected to the frame 1 to accommodate composite pipes of different lengths.

[0037] In an optional embodiment, the flared part 32 includes a mounting part 321 and a flared structure 322 connected to the mounting part 321. The mounting part 321 is connected to the first driving member 31, and the flared structure 322 is conical. The first preset diameter of the flared structure 322 is larger than the diameter of the composite tube, so as to form a uniform flange port at the end of the inner tube in the composite tube, and ensure the quality and consistency of the flaring.

[0038] Understandably, since the flaring structure 322 is set as a cone, during the flaring process, the smaller diameter part of the flaring structure 322 enters the inner tube first. When the diameter of the flaring structure 322 is basically the same as or slightly smaller than the diameter of the inner tube, the flaring structure 322 abuts against the inner wall of the inner tube. During the continued driving of the first driving member 31, the diameter of the flaring structure 322 is larger than the diameter of the inner tube, so that the end of the inner tube is flared under the outward spreading force of the flaring structure 322. The aforementioned first preset diameter is the diameter when an outward spreading force can be applied to the end of the inner tube. Its specific value can be changed according to the diameter of the inner tube, which will not be elaborated here.

[0039] In an optional embodiment, the flared part 32 is detachably connected to the first drive part 31 so that the corresponding flared part 32 can be replaced for composite pipes of different diameters to accommodate more composite pipes of different specifications.

[0040] In an optional embodiment, the rotating assembly 4 includes a second driving member 41 mounted on the frame 1 and a transmission rod 42 connected to the second driving member 41 and arranged in pairs. The composite tube can be placed on the two transmission rods 42, and the second driving member 41 can drive the transmission rods 42 to rotate so as to drive the composite tube to rotate.

[0041] Understandably, each transmission rod 42 is directly or indirectly connected to the second driving member 41, and the paired transmission rods 42 rotate in the same direction, so that the composite tube supported between the two transmission rods 42 can rotate in place. In this embodiment, the second driving member 41 is a servo motor.

[0042] Understandably, when the inner tube of the composite pipe is flared, the flanged end and the outer tube end form a mutual abutment. However, at this time, the two are in a relatively movable state. During the process of moving the composite pipe to the rotating component 4 and being driven to rotate by the rotating component 4, the flanged end and the outer tube end will be relatively displaced, causing the welding component 6 to be unable to weld the flanged end and the outer tube end together.

[0043] In an optional embodiment, the flaring system further includes a positioning component 5 disposed on one side of the flaring component 3. The positioning component 5 is capable of fitting the flanged port with the end of the outer tube, such that the flanged end and the end of the outer tube abut against each other, so that the welding component 6 can weld the two together.

[0044] In an optional embodiment, the positioning component 5 includes a third driving member 51 and a positioning member 52 connected to the third driving member 51. The third driving member 51 can drive the positioning member 52 to move in a first direction. With the help of other limiting structures, the positioning member 52 can abut against the inner tube, thereby abutting the flanged end against the outer tube end.

[0045] Understandably, the third drive component 51 is a cylinder.

[0046] In an optional embodiment, the positioning component 5 further includes a fourth driving member 53 and a pressure plate 54 connected to the fourth driving member 53, wherein the fourth driving member 53 is capable of driving the pressure plate 54 to move along a second direction to fix the composite tube in the second direction.

[0047] Understandably, the first direction is horizontal, and the second direction is vertical. That is, the third driving component 51 and the positioning component 52 can position the composite tube horizontally, while the fourth driving component 53 can drive the pressure plate 54 to abut against the composite tube, achieving vertical positioning of the composite tube and preventing displacement during rotation. It is worth noting that in this embodiment, the positioning of the composite tube in the first and second directions does not fix the composite tube, but only positions it in a preset position. This does not prevent the composite tube from being driven to rotate by the rotating component 4, thereby enabling the welding component 6 to weld the inner and outer tubes of the composite tube together.

[0048] In an alternative embodiment, reference Figure 1 and Figure 2 As shown, the clamping and moving assembly 2 includes several sets of clamping structures arranged in pairs on the frame 1. There is a clamping space between each pair of clamping structures to clamp the composite tube and prevent the composite tube from moving when it is flared.

[0049] In an optional embodiment, each holding structure includes a fifth driving member 21 and a holding baffle 22 connected to the fifth driving member 21. The two holding baffles 22 are configured to support the composite tube and move along the second direction with the fifth driving member 21, so as to drive the supported composite tube to move up and down, thereby aligning the composite tube with the flaring assembly 3 and unloading the flared composite tube.

[0050] In an optional embodiment, the flaring system further includes a detection component connected to the control component, which is capable of detecting the position of the composite tube and transmitting the detection signal to the control component, thereby causing the control component to issue an execution command to cause the flaring component 3 to flare the composite tube in place.

[0051] Understandably, the detection components can be detection devices such as metal proximity sensors or infrared beam sensors. No specific type is limited here; it depends on the actual situation.

[0052] In summary, the working process of the composite tube flaring system shown in this application is as follows: the composite tube to be welded is placed in the clamping space of the clamping and moving assembly; the fifth driving member drives the clamping baffle to move downward to the target position; the first limiting member abuts against the rear end of the composite tube; the first driving member drives the flaring member to move towards the composite tube and continuously presses against the inner tube of the composite tube, causing the end of the inner tube to flare outward to form a flanged port; then the flared composite tube is transferred to the rotating assembly, so that the two transmission rods support the composite tube and rotate under the action of the second driving member; at the same time, the third driving member drives the positioning member to move towards the composite tube to clamp the composite tube, so that it is fixed in the horizontal direction; the fourth driving member drives the pressure plate to move downward to abut against the top of the composite tube, so that it is fixed in the vertical direction, preventing the composite tube from shifting position during the rotation of the transmission rods; then, the welding assembly performs laser welding on the rotating composite tube, welding the flanged end of the inner tube to the end of the outer tube. This system has a high degree of automation, and the automatic welding and welding during rotation ensure uniform welding between the outer tube and the inner tube, thereby improving the welding strength and stability and avoiding defects that may be caused by manual welding.

[0053] The above is only one specific implementation of this application, and any other improvements made based on the concept of this application shall be considered within the scope of protection of this application.
