Description

Technical Field

[0001] This utility model belongs to the technical field of heat dissipation through spinning tubes, specifically relating to a biomimetic heat dissipation fin-cooled spinning tube. Background Technology

[0002] The wire drawing tube is a core consumable component in high-speed wire rod production lines. It is mainly used to coil high-temperature rolled wire into a regular ring structure. The long-term high-temperature working environment makes the wire drawing tube prone to wear. In order to reduce the wear on the wire drawing tube, heat dissipation fins are usually installed on the outer surface of the wire drawing tube.

[0003] Heat dissipation fins are welded to the outer wall of the spinning tube to increase the heat dissipation area and improve its heat dissipation efficiency. The larger the heat dissipation area of ​​the fins, the higher the heat dissipation efficiency of the spinning tube under operating conditions. However, the increased fin area causes the spinning tube to dissipate heat rapidly when the machine is stopped, resulting in an excessive temperature difference between the spinning tube and the residual high-temperature area. This generates a huge thermal reaction force, and the repeated start-stop thermal cycle can induce and accelerate thermal fatigue cracks, reducing the service life of the spinning tube.

The rotation axes at both ends of the rotating rod are perpendicular to the moving direction of the main plate. The slide block is slidably connected to the side plate and moves along the length direction of the side plate.

[0008] Each of the drive units corresponds to one of the heat conduction units and is used to drive the motherboard to move.

[0009] In one possible implementation, the driving unit includes:

[0010] A water storage tank is fixedly connected to the outer wall of the pipe.

[0011] A drive plate, slidably connected to the water storage tank, moves along the spiral direction of the fins, and is also fixedly connected to the main board; and

[0012] A pressure reducing valve is installed in the water storage tank;

[0013] A first elastic member is fixed between the inner wall of the water storage tank and the drive plate, and the first elastic member has a preload force that causes the drive plate to move closer to the water storage tank.

[0014] In one possible implementation, the side plate has a sliding groove on the side facing the main board that is adapted to slide the slide block. The side plate also has an expansion cavity and a plurality of through holes connecting the sliding groove and the expansion cavity. The expansion cavity is connected to the water storage tank. A blocking component is provided between the expansion cavity and the water storage tank. The blocking component is used to connect or block the expansion cavity and the water storage tank.

[0015] The limiting component includes:

[0016] A limiting block is disposed in the through hole, the limiting block is slidably connected to the side plate, and the moving direction of the limiting block is perpendicular to the length direction of the side plate;

[0017] The second elastic member is fixed between the side plate and the limiting block, and the second elastic member has a preload force that causes the limiting block to move along the groove toward the expansion cavity.

[0018] In one possible implementation, the blocking component further includes:

[0019] A connecting pipe, connecting the water storage tank and the expansion chamber; and

[0020] An opening / closing element is provided on the connecting pipe and is used to control the opening and closing of the connecting pipe.

[0021] In one possible implementation, the drive unit further includes a temporary storage tank connected to the water storage tank. The temporary storage tank is located on the side of the water storage tank away from the pipe. The pressure reducing valve is installed at the connection between the temporary storage tank and the water storage tank.

[0029] This invention provides a biomimetic heat dissipation finned cooling spinner, which, compared to existing technologies, minimizes the heat dissipation area by keeping the two side plates of each heat-conducting unit in contact with the main board when the spinner is not in operation. When the spinner is in operation, the side plates are rotated to separate from the main board, allowing heat dissipation to continue from the surfaces where the main board and side plates were originally in contact, thus increasing the heat dissipation area. By altering the heat dissipation area of ​​the heat-conducting unit, this invention maximizes the heat dissipation efficiency of the spinner when in operation and minimizes it when not in operation. This avoids excessive temperature differences between the spinner and residual high-temperature areas after shutdown, reducing thermal responsiveness and mitigating thermal fatigue during use, thereby extending the spinner's service life.

[0041] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0042] Please refer to the following: Figures 1 to 6This invention describes a biomimetic heat dissipation finned cooling wire-spinning tube. A biomimetic heat dissipation finned cooling wire-spinning tube includes a tube body 10, multiple heat-conducting units 20, and a driving unit 30. Fins are spirally fixed to the outer circumference of the tube body 10, and the fins include multiple spaced-apart spliced ​​fins 101. Multiple heat-conducting units 20 are correspondingly arranged between adjacent spliced ​​fins 101. Each heat-conducting unit 20 includes a main plate 201 slidably connected to the outer wall of the tube body 10, two side plates 202 respectively disposed on both sides of the main plate 201, a rotating rod 203 disposed between the side plates 202 and the main plate 201, and a limiting component for fixing the rotating rod 203 to the side plates 202. The main plate 201 extends along the fins... The spiral direction is such that the line connecting the two side plates 202 is perpendicular to the moving direction of the main plate 201. The side plates 202 are rotatably connected to the outer wall of the tube body 10. The rotation axis of the side plates 202 is perpendicular to the plate surface of the main plate 201. One end of the rotating rod 203 is rotatably connected to the main plate 201, and the other end is rotatably connected to the slide block 2031. The rotation axes at both ends of the rotating rod 203 are perpendicular to the moving direction of the main plate 201. The slide block 2031 is slidably connected to the side plate 202 and moves along the length of the side plate 202. The driving unit 30 corresponds to the heat conduction unit 20 and is used to drive the main plate 201 to move.

[0043] Optionally, the drive unit 30 can be a telescopic device, such as a telescopic cylinder or a hydraulic cylinder.

[0044] It should be noted that the side plate 202 that abuts against the tube body 10 has a recessed compensation cavity. The compensation cavity contains multiple compensation heat-conducting blocks. The compensation heat-conducting blocks are slidably connected to the side plate 202. The direction of movement of the compensation heat-conducting blocks is perpendicular to the length direction of the side plate 202. A deformation element is fixed between the compensation heat-conducting blocks and the side plate 202. The deformation element has a pre-tightening force that ensures that the compensation heat-conducting blocks are always pressed against the outer wall of the tube body 10 during the rotation of the side plate 202, thus dynamically compensating to avoid suspension.

[0045] In the biomimetic heat dissipation finned cooling wire-spinning tube provided in this embodiment, when the wire-spinning tube is not in operation, the side plate 202 is attached to the main board 201. When the wire-spinning tube is in operation, the main board 201 is driven to move by the drive unit 30. The main board 201 drives the rotating rod 203 to move synchronously. At this time, the slide 2031 slides on the side plate 202 following the rotating rod 203. After the slide 2031 moves to the preset position of the side plate 202, the limiting component is activated, so that the slide 2031 and the side plate 202 remain relatively stationary, thereby limiting the position of the rotating rod 203 on the side plate 202. Then the drive... Unit 30 restarts and drives the main board 201 to move in the reverse direction. Under the action of the limiting component, the slide 2031 cannot move along the side plate 202. As a result, during the reverse movement, the main board 201 drives the side plate 202 to rotate through the rotating rod 203, causing the side plate 202 to separate from the main board 201. After the spinning tube operation is completed, the drive unit 30 starts and drives the rotating rod 203 to move through the main board 201, so that the side plate 202 and the main board 201 are in contact. Then the limiting component releases the restriction on the slide 2031, and the drive unit 30 restarts and drives the main board 201 and the rotating rod 203 to reset.

[0046] Compared with existing technologies, in the non-working state, the two side plates 202 in each heat-conducting unit 20 of the spinning tube are in contact with the main board 201, minimizing the heat dissipation area. In the working state, the side plates 202 are rotated to separate from the main board 201, allowing the surfaces of the main board 201 and side plates 202 that were originally in contact to dissipate heat, thus increasing the heat dissipation area. This invention, by changing the heat dissipation area of ​​the heat-conducting unit 20, maximizes the heat dissipation efficiency of the spinning tube in the working state and minimizes it in the non-working state. This avoids excessive temperature differences between the spinning tube and the residual high-temperature area after shutdown, reduces thermal reaction force, and thus slows down thermal fatigue during use, thereby improving the service life of the spinning tube.

[0047] Another modified embodiment of the drive unit 30 is that the drive unit 30 includes a water storage tank 301, a drive plate 302, a pressure reducing valve 303, and a first elastic member 304. The water storage tank 301 is fixedly connected to the outer wall of the pipe body 10; the drive plate 302 is slidably connected to the water storage tank 301 and moves along the spiral direction of the fins. The drive plate 302 is also fixedly connected to the main plate 201; the pressure reducing valve 303 is disposed in the water storage tank 301; the first elastic member 304 is fixedly connected between the inner wall of the water storage tank 301 and the drive plate 302. The first elastic member 304 has a preload force that causes the drive plate 302 to move closer to the water storage tank 301. The first elastic member 304 may be a spring or a spring rod.

[0048] During the operation of the spinning tube, the temperature rises, causing the temperature of the water storage tank 301 to rise as well. This causes the water in the water storage tank 301 to evaporate into water vapor. The water vapor compresses the drive plate 302, causing the drive plate 302 to extend outward from the water storage tank 301. This pushes the main plate 201 out from between the two side plates 202. After the main plate 201 is pushed out to the preset position, the pressure reducing valve 303 opens, releasing the water vapor in the water storage tank 301. At this time, the first elastic element 304 releases its elastic force to retract the drive plate 302, thereby pulling the main plate 201 back.

[0049] In some embodiments, see Figure 2 and Figure 3 The side plate 202 facing the main board 201 has a sliding groove 2021 that is adapted to slide the slide block 2031. The side plate 202 also has an expansion cavity 2022 and multiple through holes 2023 connecting the sliding groove 2021 and the expansion cavity 2022. The expansion cavity 2022 is connected to the water storage tank 301. A blocking component is provided between the expansion cavity 2022 and the water storage tank 301. The blocking component is used to connect or block the expansion cavity 2022 and the water storage tank 301. The limiting component includes a limiting block. 204 and the second elastic member 205, the limiting block 204 is disposed in the through hole 2023, the limiting block 204 is slidably connected to the side plate 202, and the moving direction of the limiting block 204 is perpendicular to the length direction of the side plate 202; the second elastic member 205 is fixed between the side plate 202 and the limiting block 204, and the second elastic member 205 has a preload force that causes the limiting block 204 to move along the slide groove 2021 towards the expansion cavity 2022. The second elastic member 205 can be a spring or a spring rod.

[0050] The blocking assembly also includes a connecting pipe and an opening / closing element. The connecting pipe is connected to the water storage tank 301 and the expansion chamber 2022. The opening / closing element is located on the connecting pipe and is used to control the opening and closing of the connecting pipe. The opening / closing element is a valve or a pump.

[0051] After the water vapor in the water storage tank 301 enters the expansion chamber 2022, it compresses the limiting block 204, causing it to extend outward from the through hole 2023. This causes the limiting block 204 to abut against the slide 2031, thus fixing the slide 2031 relative to the side plate 202. Before the pressure reducing valve 303 releases the water vapor, the opening and closing element changes from the open state to the closed state to maintain the air pressure in the expansion chamber 2022, thereby fixing the position of the limiting block 204. When the slide 2031 needs to be reset, the feeding tube... When the operation stops, the cooling plate inside the water tank 301 starts working, causing the temperature inside the water tank 301 to drop, causing water vapor to condense into water droplets. At the same time, the opening and closing parts change from the closed state to the open state, thereby allowing the water vapor in the expansion chamber 2022 to flow back into the water tank 301, where it condenses into water droplets. At this time, the limiting block 204 retracts into the through hole 2023 under the action of the second elastic element 205, causing the limiting block 204 to separate from the slide 2031.

[0052] In some embodiments, see Figure 2 The drive unit 30 also includes a temporary storage box 305 connected to the water storage tank 301. The temporary storage box 305 is located on the side of the water storage tank 301 away from the pipeline. A pressure reducing valve 303 is installed at the connection between the temporary storage box 305 and the water storage tank 301. A return pipe 3051 is also connected between the water storage tank 301 and the temporary storage box 305. A power pump 30511 is installed on the return pipe 3051.

[0053] During the depressurization process of the water storage tank 301, some water vapor is released into the temporary storage tank 305 by opening the pressure reducing valve 303. After the temperature in the water storage tank 301 drops, the water vapor in the temporary storage tank 305 condenses into water droplets, and then returns to the water storage tank 301 through the return pipe 3051 via the power pump 30511, thereby increasing the utilization rate of the water in the water storage tank 301.

[0054] In some embodiments, see Figure 2 and Figure 3 The main board 201 has a first air guide cavity 2011 that communicates with the outside. The side wall of the main board 201 facing the side plate 202 has a first ventilation hole 2012 that communicates with the first air guide cavity 2011. The side plate 202 has a second air guide cavity 2024 that communicates with the outside. The side of the side plate 202 facing the main board 201 has a second ventilation hole 2025 that communicates with the second air guide cavity 2024. The first ventilation hole 2012 and the second ventilation hole 2025 are not aligned.

[0055] During the operation of the spinning tube, an external air-cooling component is provided, which is a standard feature and will not be described in detail here. The air blown out by the air-cooling component enters the first air guide cavity 2011 and is blown out from the first ventilation hole 2012, and enters the second air guide cavity 2024 and is blown out from the second ventilation hole 2025. This creates a swirling airflow between the main board 201 and the side plate 202, which quickly removes heat from the surface of the spinning tube and improves the heat dissipation efficiency of the spinning tube.

[0056] In some embodiments, see Figure 2 and Figure 5 The first air guide cavity 2011 is also provided with an air guide assembly 40, which includes an air baffle 401 and an air guide cover 402. The air baffle 401 is fixed to the side near the first ventilation hole 2012 and extends along the length of the main board 201. The air guide cover 402 is fixed to the side of the air baffle 401 facing the opening of the first air guide cavity 2011 and has a triangular cross section.

[0057] After the cold air enters the first air guide cavity 2011, it is divided into two streams by the air guide cover 402 and the air baffle 401. The two streams of cold air are blown out from the first ventilation hole 2012 respectively, so that the air volume blown out from the two first ventilation holes 2012 is equal.

[0058] In some embodiments, see Figure 5 and Figure 6 The width of the air outlet of the first ventilation hole 2012 is smaller than the width of the air inlet of the first ventilation hole 2012, and the width of the air outlet of the second ventilation hole 2025 is smaller than the width of the air inlet of the second ventilation hole 2025.

[0059] The first ventilation hole 2012 and the second ventilation hole 2025 have trapezoidal cross sections. The trapezoidal structure increases the air velocity by gradually reducing the air outlet cross section, which further accelerates the removal of heat from the surface of the spinning tube, thereby further improving the heat dissipation efficiency of the spinning tube.

[0060] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
