Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum tube cooling, and particularly relates to an aluminum tube extrusion cooling device. Background Art

[0002] Extruded aluminum tube manufacturing is a metal processing technology that heats aluminum billets to a certain temperature and then uses a die to extrude and shape aluminum tubes of the desired shape and size. In the extruded aluminum tube manufacturing process, the aluminum billet needs to be heated to a softened state, then placed in a die, and pressure is applied by an extruder to plastically deform the aluminum billet in the die to form the desired aluminum tube shape.

[0003] The main cooling methods for aluminum tube extrusion include natural cooling and forced cooling. Natural cooling means placing the extruded aluminum tube naturally and taking away the heat through natural convection of air. This method has a slower cooling speed and is suitable for situations where rapid cooling is not required.

[0004] Forced cooling is to speed up the cooling speed by using cooling medium (such as water, oil, air, etc.) through manual intervention. In the forced cooling process, a thermometer is often used to control the temperature change in the cooling process to prevent uneven cooling or overcooling. However, the thermometer is easily interfered by the cooling medium during the measurement of the aluminum tube, which makes the measurement result prone to large errors, resulting in overcooling and deformation of the aluminum tube.

[0005] Therefore, it is necessary to provide an aluminum tube extrusion cooling device to solve the problems raised in the above background technology. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0042] See also Figures 1 to 7 As shown, an aluminum tube extrusion cooling device is characterized by comprising:

[0043] A support 1, on which a driving roller 3 is rotatably mounted;

[0044] A transport and polishing mechanism 2 is fixed on the bracket 1;

[0045] Two cooling components 5 are arranged and symmetrically fixed on the bracket 1;

[0046] The cooling adjustment mechanism 4 is arranged in two and fixed on the bracket 1 corresponding to the driving roller 3. Specifically, the cooling adjustment mechanism 4 includes:

[0047] A U-shaped plate 41 is fixed on the bracket 1 and has a feeding port corresponding to the driving roller 3;

[0048] A base 42 is fixed on the U-shaped plate 41 and has two slideways on it, on which a slide table 43 is slidably arranged;

[0049] The telescopic machine 44 is fixed on the U-shaped plate 41, and the output end is fixed on the slide 43;

[0050] A U-shaped plate 2 is fixed on the bracket 1, and a slide seat 46 is slidably provided in the U-shaped plate 2;

[0051] An adjusting roller 47 is rotatably disposed on the slide seat 46;

[0052] A gear rack member 45 is mounted on the U-shaped plate 2 and driven by a motor 2 48, and the gear rack member 45 is also connected to the slide 46; and

[0053] The monitoring component 49 is fixed on the U-shaped plate 2 and is located below the cooling assembly 5. The monitoring component 49 is similar to a telescopic rod structure, in which a compression spring is installed, and a ball is rotatably provided on the top.

[0054] like Figure 1-Figure 4 As shown, the utility model also includes: the gear rack component 45 is a single-wheel double-rack structure, and the double racks are fixedly connected to the slide seat 46 respectively; the cooling assembly 5 includes an outer cooling pipe 51 and an inner cooling pipe 52, both of which are fixed on the U-shaped plate 2, and nozzles 53 are fixed on the opposite sides, and the outer cooling pipe 51 and the inner cooling pipe 52 are also connected by a connecting pipe 54.

[0055] The extruded high-temperature aluminum tube falls to the slide 43 under the action of the extruder, and the slide 43 slides on the base 42 under the action of the telescopic machine 44, so that the aluminum tube is aligned with the feed port. At this time, the aluminum tube gradually enters the cooling assembly 5 under the action of the transport and polishing mechanism 2, so that the inner cooling tube 52 will be inside the aluminum tube to cool the inside, and the outer cooling tube 51 will cool the surface of the aluminum tube.

[0056] When the aluminum tube is completely transported to the cooling assembly 5 by the transport and polishing mechanism 2, the motor 2 48 rotates counterclockwise to make the slide 46 slide back and forth, so that the aluminum tube is clamped under the action of the adjusting roller 47 and the driving roller 3, and the central axis position of the aluminum tube coincides with the inner cooling tube 52, and the monitoring component 49 is in contact with the surface of the aluminum tube.

[0057] After the above operation is completed, the driving roller 3 and the cooling assembly 5 are started, that is, the aluminum tube starts to rotate under the action of the driving roller 3 and the adjusting roller 47, so that the cooling assembly 5 can evenly cool the aluminum tube to prevent the aluminum tube from being deformed due to uneven local cooling. At the same time, during the rotation of the aluminum tube, the monitoring component 49 can monitor the roundness of the aluminum tube in real time. The roundness of the aluminum tube will change as the aluminum tube is affected by thermal expansion and contraction. Figure 6 The curve is a smooth curve, and the cooling component 5 can control the temperature of its cooling water according to the curve, that is, Figure 7 As described above, when the temperature of the aluminum tube is high, it is cooled with a higher water temperature to prevent the high-temperature aluminum tube from deforming under the high temperature difference. Conversely, after the temperature is lowered, the water temperature is simultaneously lowered for cooling. This method can effectively reduce the deformation of the aluminum tube due to thermal expansion and contraction during cooling, thereby ensuring the cooling efficiency of the aluminum tube and improving the yield rate of the aluminum tube.

[0058] After the aluminum tube is cooled, the aluminum tube exits the cooling assembly 5 under the action of the transport and polishing mechanism 2 and falls onto the base 42. Then the telescopic machine 44 is started to make the aluminum tube after cooling fall to the sorting mechanism, and at the same time, the newly produced high-temperature aluminum tube is at the conveying port.

[0059] like Figure 6 The curve shown is a qualified aluminum tube. If the actual monitoring shows Figure 6 If the curve is not smooth, it is an unqualified aluminum tube, which will be fed back to the sorting device for sorting, which can further improve the overall manufacturing efficiency of the aluminum tube.

[0060] like Figure 5 As shown, the utility model also includes: the transport and polishing mechanism 2 includes:

[0061] The adjusting rod 21 is arranged in multiples, one end of which is fixed on the bracket 1, and the other end of which is fixed with a bearing platform 22;

[0062] Roller groups 24, two in total, are supported and fixed on the bearing platform 22;

[0063] Two ladder frames 23 are fixed on the carrying platform 22; and

[0064] The belt 25 is sleeved on the roller set 24 .

[0065] It also includes: the roller group 24 is driven by the motor three; a grinding belt is fixed on the surface of the belt 25; and the adjustment rod 21 can adjust the height of the support platform 22 under the feedback of the monitoring component 49.

[0066] During the cooling and rotating process of the aluminum tube, the grinding belt can grind the surface of the aluminum tube to avoid impurities on the surface of the aluminum tube during the cooling process, thereby improving the smoothness of the aluminum tube. Figure 6 The height of the support platform 22 is adjusted appropriately to avoid excessive grinding of the aluminum tube, which may cause scratches on the surface of the aluminum tube.

[0067] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
