Description

Technical Field

[0002] Aircraft are flying objects that are manufactured by humans, can take off the ground, fly in space, and are controlled by humans to fly in the atmosphere or in space outside the atmosphere. Aircraft are mostly processed with titanium alloy materials, which have the characteristics of good corrosion resistance, low specific gravity, high specific strength, and excellent affinity with the human body. During the processing, most of them are carried out at high temperatures. After one process is completed, the titanium alloy workpiece often needs to be cooled before the next process can be carried out.

Another cooling method uses water spraying for rapid cooling. Although this cooling method shortens the cooling time, it adds a material drying process, which also increases the time of the entire processing step, reduces overall production efficiency, and increases the labor intensity of workers.

[0022] A cooling device for machining titanium alloy workpieces for aircraft, combined with Figure 1 to Figure 2 As shown, it includes a cooling box 1 and a refrigerating water tank 7, wherein a workpiece placement rack 2, a fan 3 and a serpentine heat exchange water pipe 4 are arranged inside the cooling box 1, wherein the workpiece placement rack 2 is used to place titanium alloy workpieces; the fan 3 is located below the workpiece placement rack 2, and the fan 3 is used to perform wind cooling on the titanium alloy workpieces; the serpentine heat exchange water pipe 4 is located between the workpiece placement rack 2 and the fan 3, and both ends of the serpentine heat exchange water pipe 4 respectively pass through the cooling box 1 and are connected to the refrigerating water tank 7 through a connecting pipe, and the refrigerating water tank 7 is used to provide circulating cooling water to the serpentine heat exchange water pipe 4, and the circulating cooling water in the serpentine heat exchange water pipe 4 is used to exchange heat with the wind blown out by the fan 3 to reduce the wind temperature, thereby improving the efficiency of wind cooling.

[0023] The workpiece placement rack 2 includes two vertical plates 21, which are arranged on the inner walls of the cooling box 1 on both sides. A plurality of horizontal placement mesh plates 22 are arranged between the vertical plates 21 from top to bottom. Figure 3 As shown, the placement mesh plate 22 is composed of a plurality of staggered transverse tubes. The placement mesh plate 22 is used to place the titanium alloy workpiece, and the placement mesh plate 22 adopts a mesh design, which not only allows cold air to pass through to achieve cooling of each titanium alloy workpiece on the placement mesh plate 22, but also the contact area between the placement mesh plate 22 and the titanium alloy workpiece is small, which is beneficial to the overall cooling of the titanium alloy workpiece and improves the cooling efficiency.

[0024] The serpentine heat exchange pipe 4 includes a lower serpentine heat exchange pipe 41 and an upper serpentine heat exchange pipe 42 arranged horizontally. The structural schematic diagram of the lower serpentine heat exchange pipe 41 and the upper serpentine heat exchange pipe 42 is shown in FIG. Figures 4 to 5 As shown. The upper serpentine heat exchange water pipe 42 is arranged above the lower serpentine heat exchange water pipe 41, and the inner end of the lower serpentine heat exchange water pipe 41 is connected to the inner end of the upper serpentine heat exchange water pipe 42 through a connected connecting pipe 43. The outer end of the upper serpentine heat exchange water pipe 42 passes through the cooling box 1 and is connected to the water outlet of the refrigerating water tank 7 through a connected water inlet pipe. A pump 6 is provided on the water inlet pipe, and the pump 6 is used to pump the circulating cooling water in the refrigerating water tank 7 into the serpentine heat exchange water pipe 4; the outer end of the lower serpentine heat exchange water pipe 41 passes through the cooling box 1 and is connected to the water inlet of the refrigerating water tank 7 through a connected water outlet pipe, so that the circulating cooling water after heat exchange flows back to the refrigerating water tank 7.

[0025] The winding direction of the upper serpentine heat exchange water pipe 42 is horizontally rotated 90° compared to the lower serpentine heat exchange water pipe 41. Such a design can not only improve the heat exchange effect of the wind blown out by the fan 3, but also make the wind after heat exchange blow out evenly, thereby helping to improve the cooling effect of the titanium alloy workpiece.
