Background Technology

[0002] Finned tubes are a type of heat exchange element. To improve heat exchange efficiency, fins are typically added to the surface of the heat exchange tube, increasing its external (or internal) surface area, thereby enhancing heat exchange efficiency. External finned tubes have fins on the outer surface of the heat exchange tube; the shapes of the fins include square finned tubes, circular finned tubes, and spiral finned tubes, among others.

[0003] After the external finned tubes are manufactured, they usually need to be cut to a certain size to accommodate different pipe connection methods and length requirements. However, during the cutting process, it is essential to ensure that the external finned tubes are in a stable state; otherwise, deviations may occur. Therefore, there is an urgent need for a cutting device that can stably clamp the finned tubes and maintain stability during cutting. Summary of the Invention

[0006] Two clamping members are arranged at intervals in the left-right direction, and matching grooves are provided on their opposite sides. The two clamping members are respectively connected to the driving mechanism, which can drive the two clamping members to move closer or further apart.

[0007] At least three limiting members are slidably mounted on each of the clamping members. One end of each limiting member is a limiting part that extends into the groove, and the other end extends away from the limiting part to form a connecting part. The shape of the limiting part matches the outer diameter of the finned tube. The telescopic mechanism is connected to the two connecting parts and is used to drive the upper limiting members of the two clamping members to move towards each other to extend between two adjacent fins and clamp the finned tube.

[0023] Reference Figure 1-3 This application proposes an embodiment of a finned tube cutting device, characterized in that it includes a worktable 10 and a drive mechanism 20, a telescopic mechanism 30, and two clamping members 40 mounted on the worktable 10.

[0024] Two clamping members 40 are arranged at intervals in the left-right direction, and matching grooves 41 are provided on the opposite side of the two clamping members 40. The two clamping members 40 are respectively connected to the driving mechanism 20, and the driving mechanism 20 can drive the two clamping members 40 to move closer or further away from each other.

[0025] At least three limiting members 50 are slidably mounted on each of the clamping members 40. One end of each limiting member 50 is a limiting part 51 that extends into the groove 41, and the other end extends away from the limiting part 51 to form a connecting part 52. The shape of the limiting part 51 matches the outer diameter of the finned tube. The telescopic mechanism 30 is connected to the two connecting parts 52 and is used to drive the limiting members 50 of the two clamping members 40 to move towards each other to extend into the fins and clamp the finned tube, so as to limit the finned tube as a whole within the two grooves 41.

[0026] To ensure stable clamping of the finned tube by the cutting device, a limiting member 50 is provided inside the groove 41. The limiting members 50 are connected by a linkage mechanism 60. By adjusting the distance between two adjacent limiting members 50, the limiting member 50 corresponds to the gap between two adjacent outer fins. The telescopic mechanism 30 drives all the limiting members 50 to move towards each other until the limiting part 51 extends between two adjacent fins and abuts against the outer wall of the finned tube, thereby achieving positioning and clamping of the finned tube. This enables the cutting device to stably clamp and position the outer finned tube, thus preventing the outer finned tube from shifting during the cutting process.

[0027] In this embodiment, the lower ends of the two clamping members 40 are respectively provided with slide bars, and the worktable 10 is provided with slide grooves 321 that match the slide bars. The clamping members 40 are respectively installed in the slide grooves 321 so that the clamping members 40 can slide on the worktable 10. Specifically, the lower end of the worktable 10 is provided with an electric lead screw, and the slide bars at the lower ends of the clamping members 40 are respectively threaded onto the lead screw of the electric lead screw so that when the electric lead screw rotates, the two clamping members 40 move closer or further away from each other; when the finned tube is placed in the groove 41, the electric lead screw is activated to drive the two clamping members 40 to move closer to each other to clamp the fins of the finned tube.

[0028] The shape of the groove 41 matches the shape of the outer fin of the finned tube, and is suitable for square finned tubes, round finned tubes, and spiral finned tubes.

[0029] In this embodiment, the linkage mechanism 60 includes two hinged rods 61. One end of each hinged rod 61 is connected to two adjacent limiting members 50, and the other ends are hinged together. For fins at different distances on the finned tube, the distance between all the limiting members 50 can be adjusted by moving one of the limiting members 50, making it more convenient to use. After the distance between the limiting parts 51 of two adjacent limiting members 50 is adjusted, the telescopic mechanism 30 drives the two connecting members 32 to move all the limiting members 50 toward each other until the limiting part 51 extends between two adjacent fins and abuts against the outer wall of the finned tube, thereby achieving the positioning and clamping of the finned tube.

[0030] The telescopic mechanism 30 is divided into two parts. Specifically, the telescopic mechanism 30 includes two telescopic members 31 and two connecting members 32. The two telescopic members 31 are respectively arranged on the workbench 10 and located on the opposite side of the two clamping members 40. The two connecting members 32 are respectively installed on the telescopic ends of the two telescopic members 31. The connecting parts 52 of the limiting members 50 on the two clamping members 40 are respectively installed on the two connecting members 32 and can slide on the connecting members 32.

[0031] See attached document Figure 1 As shown, the connecting members 32 are respectively disposed on opposite sides of the two clamping members 40. The limiting members 50 are respectively mounted on the connecting members 32 and can slide. The telescopic member 31 drives the connecting members 32 to move closer or further apart, thereby enabling the limiting parts 51 on the two clamping members 40 to move closer or further apart. Specifically, the connecting member 32 is provided with a sliding groove 321, and the connecting part 52 is installed in the sliding groove 321 and can slide within the sliding groove 321.

[0032] In this embodiment, the connecting members 32 are respectively slidably mounted on the workbench 10, and the telescopic member 31 is a telescopic cylinder. The telescopic end of the telescopic cylinder can extend and retract to enable the two connecting members 31 to drive the limiting part 52 to move closer or further away from each other.

[0033] See attached document Figure 1 As shown, the workbench 10 is also provided with a cutting mechanism 80. The cutter 81 of the cutting mechanism is located outside the space between the two clamping members 40 to avoid affecting the placement of the finned tube. The cutting mechanism can drive the cutter to move horizontally between the two clamping members 40 to cut the finned tube.

[0034] Furthermore, in order to ensure that the limiting part 51 can be stably clamped on the outer wall of the finned tube, in this embodiment, any two of the limiting parts 50 on the two clamping parts 40 are also provided with locking components 70 for locking the two together.

[0035] In this application, the locking assembly 70 includes a locking rod 71 and a locking bolt 72. One of the hinge rods 61 of the linkage mechanism 60 is provided with an oblong hole 611. One end of the locking rod 71 is hinged to the middle of another hinge rod 61, and the other end is provided with a through hole. The tail of the locking bolt 72 passes through the through hole and the oblong hole 611 and is then installed on the other hinge rod 61 by a nut.

[0036] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
