[0002] Heat exchange tubes are one of the components of a heat exchanger, placed within the cylinder and used to exchange heat between two media. They possess high thermal conductivity and excellent isothermal properties. They are devices that can quickly transfer heat energy from one point to another with virtually no heat loss, earning them the nickname "heat transfer superconductor." Their thermal conductivity is thousands of times greater than that of copper.

[0003] Some heat exchange tubes require spirals to provide flow resistance. These spirals are produced using a spiral forming machine. Existing forming machines use a spiral forming machine that secures the ends of a sheet of material cut to a specified length. One end is fixed while the other rotates, creating a spiral shape.

[0018] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0019] According to the instruction manual Figure 1It can be seen that when the present invention is used, the rolled spiral material, i.e., the sheet material 10, is transported by the roller conveyor mechanism 1 through the limiting groove 2 of the carrier 16 to the cylinder clamping mechanism on the mounting plate 12, where it is clamped and fixed by the cylinder clamping mechanism. The pressing mechanism on the carrier 16 operates to press and fix the sheet material 10 in the limiting groove 2, and as a fixed end, the driving rotation mechanism 14 on the vertical plate 13 drives the mounting plate 12 and the cylinder clamping mechanism on the mounting plate 12 to rotate, thereby causing the sheet material 10 to be spirally formed. After the forming is completed, the cutting mechanism is activated to cut the sheet material 10 between the pressing mechanism and the roller conveyor mechanism 1. The pressing mechanism and the cylinder clamping mechanism are released, and the personnel remove the formed spiral part, and the roller conveyor mechanism 1 conveys it again, and the above process is repeated. Compared with the existing technology, the utility model does not need to be cut into sections in advance, does not need to be transported and delivered multiple times, and the feeding, fixing, forming and cutting operations are continuous, which greatly improves production efficiency, saves a lot of manual intervention work, and has a high degree of automation.

[0020] Among them, the cutting mechanism includes a motor 4, an electric slide 5, a slider 3 and a cutting knife 6. The electric slide is arranged on the upper surface of the supporting platform 16 and is designed perpendicular to the direction of the limiting groove 2. The slider 3 is fixedly connected to the moving end of the electric slide 5. The motor 4 is fixedly arranged on the slider 3. The output end of the motor 4 is connected to the cutting knife 6. A cutting groove 18 is provided on the supporting platform 16 corresponding to the position of the cutting knife 6, and the cutting groove 18 is designed perpendicular to the limiting groove 2. The depth of the cutting groove 18 is greater than the depth of the limiting groove 2, and the lowest point of the cutting knife 6 is in the cutting groove 18.

[0021] During operation, when the sheet material 10 is conveyed into the limiting groove 2, the cutting knife 6 is on one side through the electric sliding transmission, which does not affect the transmission of the sheet material 10. During cutting, the electric slide rail 5 drives the slider 3, the motor 4 and the cutting knife 6 to move along the cutting groove 18 perpendicular to the limiting groove 2 to cut the sheet material 10. It has a simple structure, a simple working principle, and is easy to repair and maintain.

[0022] Among them, the pressing mechanism includes a first door-type plate 8, a lifting cylinder 7 and a pressure plate 9. The first door-type plate 8 is arranged above the limit groove 2 and is fixedly connected to the supporting platform 16. The lifting cylinder 7 is arranged at the center position of the second door-type plate 21. The pressure plate 9 is fixedly connected to the telescopic end of the lifting cylinder 7.

[0023] During operation, the telescopic end of the lifting cylinder 7 descends, driving the pressing plate 9 to press and fix the sheet material 10 in the limiting groove 2. As the fixed end of the spiral member, the structure is simple and the pressing is stable. An anti-slip pad is provided at the bottom of the pressing plate 9 to increase the friction force when the pressing plate 9 presses the sheet material 10, further improving stability.
