It should also be understood that the term "and / or" used in this article refers to and includes any or all possible combinations of one or more associated listed items.

[0030] First, some terms involved in this utility model are explained:

[0031] Ultra-high molecular weight polyethylene (UHMWPE) refers to unbranched linear polyethylene with a molecular weight of more than 1.5 million.

[0032] The ultra-high molecular weight polyethylene lined composite pipe refers to a composite pipe in which an inner liner pipe made of ultra-high molecular weight polyethylene is arranged inside a steel pipe, and the inner liner pipe made of ultra-high molecular weight polyethylene is integrated with the steel pipe by interference fit to form a composite pipe.

[0033] like Figure 1-Figure 5 As shown, the multi-station ultra-high molecular weight polyethylene lined composite pipe flanging machine provided by the utility model is characterized by comprising:

[0034] A base 1 is provided with a sliding seat 2 slidably connected to the base 1 . A first linear drive 3 is provided between the base 1 and the sliding seat 2 . The first linear drive 3 is used for driving the sliding seat 2 to slide on the base 1 .

[0035] The sliding seat 2 is, for example but not limited to, a rectangular parallelepiped structure, in which a groove with an open top may be provided, and the sliding seat 2 can achieve sliding fit with the base 1 along the long side of the rectangular parallelepiped structure.

[0036] In which, a first partition plate 21 and a second partition plate 22 can be arranged side by side in the groove, and the first partition plate 21 and the second partition plate 22 divide the groove into a first groove 23, a second groove 24 and a third groove 25 in sequence. The first groove 23 is close to the first linear drive 3, and the third groove 25 is far away from the first linear drive 3.

[0037] The specific shape of the base 1 is not limited here, as long as it can play a supporting role and the sliding seat 2 can slide thereon.

[0038] It should be noted that the first linear drive 3, and the second linear drive 4, the third linear drive 5 and the fourth linear drive 61 described below may be pneumatic cylinders, hydraulic cylinders or electric push rods.

[0039] In this example, the first linear drive 3, the second linear drive 4, the third linear drive 5 and the fourth linear drive 61 are described by taking a pneumatic cylinder as an example. The principles of using a hydraulic cylinder and an electric push rod are the same as those of a pneumatic cylinder, and are not described in detail here.

[0040] For example, the base 1 includes a vertically arranged mounting plate 11, and the cylinder body of the pneumatic cylinder of the first linear actuator 3 can be fixed to the side of the mounting plate 11 away from the sliding seat 2 by means of bolts 12, and the movable rod (also referred to as a piston rod) of the pneumatic cylinder of the first linear actuator 3 passes through the mounting plate 11 and is fixedly connected to the sliding seat 2. One end of the movable rod can be fixedly connected to the sliding seat 2 by means of a threaded connection.

[0041] A second linear drive 4 and a sliding rod 51 are provided on the sliding seat 2. The sliding rod 51 is slidably matched with the sliding seat 2. The sliding direction of the sliding rod 51 is parallel to the sliding direction of the sliding seat 2. One end of the sliding rod 51 is connected to the second linear drive 4, and the other end is connected to the flanging mold mounting part 52. The flanging mold mounting part 52 is opened and connected to the first flanging mold 7. The power of the second linear drive 4 is less than that of the first linear drive 3.

[0042] For example, the pneumatic cylinder as the second linear actuator 4 is arranged in the second groove 24, and the cylinder body of the pneumatic cylinder as the second linear actuator 4 is fixed on the first partition 21, and the movable rod of the pneumatic cylinder as the second linear actuator 4 passes through the first partition 21 and is fixedly connected to the connecting plate 26, and the two sliding rods 51 are fixedly connected to the connecting plate 26, and the two sliding rods 51 are arranged in parallel and pass through the second partition 22 and the groove wall of the groove in sequence, and the flanging mold mounting member 52 is fixedly connected to one end of the two sliding rods 51 extending out of the groove. By setting two parallel sliding rods 51, the flanging mold mounting member 52 can be prevented from rotating, and in addition, good guidance can be provided.

[0043] See also Figure 6 As shown, the first flanging die 7 includes, for example but not limited to, a die body 71, the die body 71 has a circular blind hole, the blind hole can be a stepped hole, an axial core 72 is arranged in the blind hole, the axial core 72 is truncated, and the large diameter end of the axial core 72 is connected to the bottom of the blind hole, and the small diameter end extends out of the blind hole. When flanging the ultra-high molecular weight polyethylene lined composite pipe 8 to be flanged, the axial core 72 is inserted into the ultra-high molecular weight polyethylene lined pipe 81 to be flanged, the end of the steel pipe 82 is located in the blind hole, and the first flanging die 7 arranged at the end of the steel pipe 82 is moved toward each other along the axis of the steel pipe 82 to squeeze the end of the ultra-high molecular weight polyethylene lined pipe 81, so that the softened end of the ultra-high molecular weight polyethylene lined pipe 81 is deformed to at least cover the end face of the steel pipe 82. Wherein, the end of the steel pipe 82 is provided with an external thread.

[0044] The swing-type clamping mechanism 6 is located on the side of the flanging mold mounting part 52 away from the second linear drive 4, and is used to clamp the ultra-high molecular weight polyethylene lined composite pipe 8 to be flanging, and the axis of the ultra-high molecular weight polyethylene lined composite pipe 8 is coaxial with the axis of the first flanging mold 7.

[0045] It should be noted that the length of the ultra-high molecular weight polyethylene lined composite pipe 8 in the drawings of this example can be determined according to actual needs. The drawings only show the ultra-high molecular weight polyethylene lined composite pipe 8 by way of example, and do not explicitly or implicitly indicate the specific length of the ultra-high molecular weight polyethylene lined composite pipe 8.

[0046] For example but not limited to, the swing clamping mechanism 6 includes two claws 62 and a claw mounting seat, each of the claws 62 is rotatably matched with the claw mounting seat, and a fourth linear drive 61 is connected between each of the claws 62 and the claw mounting seat, and each of the fourth linear drives 61 is used to drive the corresponding claw 62 to rotate so as to clamp or release the ultra-high molecular weight polyethylene lined composite pipe 8 to be flanged.

[0047] Each of the clamping claws 62 includes a rotating connection portion and a clamping portion 621 and a driving portion 622 located on both sides of the rotating connection portion. The rotating connection portion is rotationally matched with the clamping claw mounting seat, and the driving portion 622 is connected to the fourth linear drive 61 .

[0048] When the fourth linear drive 61 contracts, the clamping parts of the two claws 62 rotate in opposite directions. At this time, the ultra-high molecular weight polyethylene lined composite pipe 8 to be flanged can be placed between the clamping parts 621 of the two claws 62. Then, the movable rod of the fourth linear drive 61 is extended, and the clamping parts 621 of the two claws 62 move toward each other to clamp the ultra-high molecular weight polyethylene lined composite pipe 8 to be flanged.

[0049] In the above scheme, two or more different types of ultra-high molecular weight polyethylene liner tubes 81 are flanged by setting two first linear drives 3 and second linear drives 4 with different powers. For example, but not limited to, when flanging an ultra-high molecular weight polyethylene liner tube 81 with a larger diameter and thicker wall thickness, the first linear drive 3 can be controlled to act to drive the sliding seat 2. At this time, the second linear drive 4 may not pass through, but move together with the sliding seat 2. Accordingly, the flanging mold mounting member 52 and the first flanging mold 7 connected to the second linear drive 4 also move together until the first flanging mold 7 completes the flanging of the ultra-high molecular weight polyethylene liner tube 81; when the diameter and wall thickness of the ultra-high molecular weight polyethylene liner tube 81 to be flanged intersect and are lower than the above, at this time, the sliding seat 2 can be first moved to a certain position by the first linear drive 3 and kept at the current position, and then the second linear drive 4 can be controlled to move so that the flanging mold mounting member 52 and the first flanging mold 7 connected to the second linear drive 4 are moved until the first flanging mold 7 completes the flanging of the ultra-high molecular weight polyethylene liner tube 81.

[0050] As an achievable method, in order to adapt to the flanging of more models of ultra-high molecular weight polyethylene lined pipes 81, the multi-station ultra-high molecular weight polyethylene lined composite pipe flanging machine also includes a third linear drive 5, the power of the third linear drive 5 is less than the power of the second linear drive 4, the third linear drive 5 is located on the side of the flanging mold mounting part 52 facing the second linear drive 4, one end of the third linear drive 5 is detachably connected to the second flanging mold, and the axis of the ultra-high molecular weight polyethylene lined composite pipe 8 is coaxial with the axis of the second flanging mold.

[0051] The second flanging mold may adopt the same structure as the first flanging mold 7 , and the difference between the two mainly lies in the size. Generally, the size of the first flanging mold 7 is larger than that of the second flanging mold.

[0052] For ease of use and to avoid the need to remove the flanging mold mounting component 52 when using the third linear drive 5 for flanging, a through hole 53 can be set on the flanging mold mounting component 52 and the first flanging mold 7 for the piston rod of the third linear drive 5 to pass through, so as to assemble the second flanging mold at the end of the piston rod of the third linear drive 5.

[0053] As an implementable method, the movable rod of the second linear drive 4 passes through the first partition plate 21 and is fixedly connected to the connecting plate 26, and the two sliding rods 51 are fixedly connected to the connecting plate 26. The two sliding rods 51 are arranged in parallel and sequentially pass through the second partition plate 22 and the groove wall of the groove. The flanging mold mounting part 52 is fixedly connected to one end of the two sliding rods 51 extending out of the groove.

[0054] The flanging die mounting member 52 may be a plate-shaped member.

[0055] As an achievable method, the third linear drive 5 is located between the two sliding rods 51, the movable rod of the third linear drive 5 is coaxially arranged with the movable rod of the second linear drive 4, and the movable rod of the third linear drive 5 is used to sequentially pass through the second partition plate 22, the groove wall of the groove and the flanging mold mounting member 52.

[0056] A connection plate movable gap is provided between the connection plate and the third linear drive 5. By providing the connection plate movable gap, the third linear drive 5 can be prevented from blocking the connection plate.

[0057] As an implementable manner, the pneumatic cylinder serving as the third linear drive 5 is disposed in the second groove 24 , and the cylinder body of the pneumatic cylinder serving as the third linear drive 5 is fixedly connected to the second partition plate 22 .

[0058] As an implementable manner, one of the assembly surface of the base 1 and the bottom surface of the sliding seat 2 is provided with a slide rail 13 , and the other is provided with a slide groove 27 slidably matched with the slide rail 13 .

[0059] In this example, a slide rail 13 is provided on the assembly surface of the base 1 , and a slide groove 27 is provided on the bottom surface of the sliding seat 2 .
