Description

Technical Field

[0001] This utility model relates to the field of cooling device technology, specifically a special titanium alloy cooling device. Background Technology

[0002] Special titanium alloy cooling devices are specialized equipment designed for rapid and efficient cooling of special titanium alloy workpieces after processing. Through forced convection and heat exchange, they promptly remove the heat generated during the workpiece processing, preventing problems such as workpiece deformation and changes in microstructure and properties caused by excessive temperature. This ensures the processing accuracy and performance of titanium alloy workpieces and has significant application value in aerospace, high-end equipment manufacturing, and other fields.

[0003] Application No. 202420793204.4 discloses a cooling device for processing titanium alloy workpieces for aircraft. This utility model can effectively improve the cooling efficiency of titanium alloy workpieces by using a workpiece placement rack, a fan, a serpentine hot water exchange pipe and a refrigeration water tank connected to the serpentine hot water exchange pipe in a cooling box, thereby improving production efficiency.

[0004] When the above-mentioned device is in use, the cooling fan is placed at the bottom of the cooling box. The cooling airflow has to pass through the serpentine water exchange pipe and multiple layers of placement mesh plates before it can reach the top placement mesh plate. This results in a significant loss of energy during the upward movement of the airflow, insufficient cooling airflow for the top workpiece, and cooling efficiency far below expectations. This may lead to uneven cooling of the workpiece, which not only affects the processing accuracy but also increases the scrap rate of the workpiece. Therefore, we propose a special titanium alloy cooling device. Utility Model Content

[0027] Structural Description: Cooling Box 1: As the main body of the device, it provides a closed space for cooling titanium alloy workpieces.

[0029] Cooling channel 3: Located at the top of cooling box 1, it is equipped with motor 10, fan blade 11 and serpentine heat exchange tube 9 to form a cooling airflow channel. After the airflow exchanges heat with the serpentine heat exchange tube 9, it blows towards the workpiece to achieve cooling.

[0030] Filter 4: Installed at the top of the cooling channel 3, it can effectively intercept debris and dust in the outside air, prevent them from entering the cooling channel 3, protect the motor 10 and fan blades 11, and at the same time prevent debris from affecting the cooling airflow quality.

[0035] Serpentine heat exchange tube 9: Placed inside the cooling channel 3, it is in full contact with the cooling airflow. The cooling water circulating inside the tube absorbs the heat of the airflow, reduces the airflow temperature, and provides low-temperature cooling air for the titanium alloy workpiece.

[0037] Fan blade 11: Connected to the output end of motor 10, it rotates at high speed under the drive of motor 10, generating airflow, which is cooled by serpentine heat exchange tube 9 and then blown onto the titanium alloy workpiece to achieve forced convection heat dissipation.

[0038] Fixed rod 12: Fixed to the inner wall of cooling box 1, cooperating with rotating sleeve 13, restricting the horizontal position of titanium alloy plate, and providing a fulcrum for the tilting movement of plate to ensure plate stability.

[0039] Rotating sleeve 13: Sleeves on fixed rod 12 and can rotate along fixed rod 12 to reduce friction between the plate and fixed rod 12 when the plate is tilted, ensuring that the plate is tilted smoothly and facilitating uniform heat dissipation.

[0040] Moving plate 14: Located inside the cooling box 1, it moves horizontally under the drive of cylinder 16. The arc-shaped groove 15 and the ventilation groove 17 on it are used to push the plate to tilt and to discharge hot air, respectively.

[0041] Arc-shaped groove 15: Set on the moving plate 14, it contacts the bottom end of the titanium alloy plate. When the moving plate 14 moves, it pushes the plate to tilt, increasing the contact area between the plate and the cooling airflow and improving the cooling effect.

[0042] Cylinder 16: Fixed to the side wall of the cooling box 1, it drives the moving plate 14 to move horizontally through the output end, providing power for the plate to tilt, and controlling the moving distance and speed of the moving plate 14.

[0043] Ventilation slot 17: Distributed on the movable plate 14, used to exhaust the hot air generated by the heat dissipation of the titanium alloy plate, and together with the inverted V-shaped air guide plate 18 and heat dissipation port 19, it forms a hot air exhaust channel.

[0044] Inverted V-shaped air guide plate 18: Installed on the inner wall of the cooling box 1 and located below the moving plate 14, it guides the hot air discharged from the ventilation slot 17 to change its flow direction and be discharged through the heat dissipation port 19, thus optimizing the hot air discharge path.

[0045] Heat dissipation vents 19: Located on both sides of the bottom of the cooling box 1, they cooperate with the inverted V-shaped air guide plate 18 to exhaust the hot air inside the cooling box 1, maintain the temperature inside the box and ensure the cooling effect.

[0046] Fixed block 20: Connected to the bottom of the movable plate 14, it slides in cooperation with the inner wall of the U-shaped limit frame 21 to provide guidance and limit for the movement of the movable plate 14, ensuring that the movable plate 14 moves smoothly.

[0047] U-shaped limiting bracket 21: fixed to the inner wall of the cooling box 1, cooperating with the fixing block 20, restricting the movement direction of the moving plate 14, preventing it from deviating, and ensuring the stability of the process of the moving plate 14 driving the plate to tilt.

[0048] Open the sealed door 2 and place the titanium alloy plate inside the cooling box 1. The top of the plate is positioned between the fixed rods 12, the outer wall is in contact with the rotating sleeve 13, and the bottom is placed on the arc-shaped groove 15 of the moving plate 14, thus completing the workpiece fixation 1. Start the pump 7, and the cooling water in the water tank 5 is pumped into the serpentine heat exchange tube 9 through the first connecting pipe 6. At the same time, start the motor 10, which drives the fan blades 11 to rotate. The airflow is cooled by passing through the serpentine heat exchange tube 9, forming cold air to initially cool the titanium alloy plate 3. Start the cylinder 16, which drives the moving plate 14 to move horizontally. The plate bottom is pushed through the arc-shaped groove 15, and the plate tilts in conjunction with the fixed rods 12 and the rotating sleeve 13. The rotating sleeve 13 rotates along the fixed rods 12 to reduce friction, and the tilting of the plate increases the heat dissipation area. The hot air is discharged through the ventilation slot 17 and, guided by the inverted V-shaped air guide plate 18, is discharged from the heat dissipation port 19. After cooling is completed, open the valve on the second connecting pipe 8, and the cooled water after heat exchange flows back to the water tank 5, completing the circulation.
