[0044] The core of the utility model is to disclose an aluminum alloy ingot loading tool to reduce the potential safety hazards of LQ3 aluminum alloy ingots during heating.

[0045] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0046] like Figure 1-Figure 2As shown, the aluminum alloy ingot 10 mentioned in the utility model refers to the LQ3 aluminum alloy ingot. For the convenience of description, it is referred to as the aluminum alloy ingot hereinafter. The LQ3 aluminum alloy ingot includes an ingot matrix 11 (3003 ingot matrix) and two brazing plates 12 (4004 brazing plates) located on both sides of the ingot matrix 11. The thickness of the brazing plate 12 is generally 20mm~80mm. The ingot matrix 11 and the brazing plate 12 are fastened and fixed by multiple steel strips 20. After the ingot is heated by a heating furnace, it is sent to a hot rolling mill for welding, and then rolled into a plate and strip, and finally subjected to finishing treatment to become a finished product. The final product is an LQ3 composite aluminum alloy brazing plate, which is generally used for air-conditioning equipment and automotive heat exchangers.

[0047] like Figure 19-20 As shown, an embodiment of the utility model discloses an aluminum alloy ingot loading tool, including a first material pad 100 and a second material pad 200 .

[0048] like Figure 3 As shown, the cross section of the upper surface of the first material pad 100 is a V-shaped structure, and the V-shaped angle is Figure 3 The second material pad 200 and the first material pad 100 are detachably connected, specifically by a snap connection or by a connection member, and the specific connection method is not limited. Figure 8 As shown, a first recessed portion 210 is provided on the upper surface of the second material pad 200 , and first supporting portions 220 for supporting the ingot base 11 are formed on both sides of the first recessed portion 210 . The first supporting portion 220 extends in the same direction as the first recessed portion 210 , and the brazing plate 12 abuts against the first material pad 100 .

[0049] Specifically, Figure 13-Figure 14 As shown, the ingot base 11 is placed vertically, and the two ends of the bottom of the ingot base 11 are supported on the first support parts 220 located on both sides of the first recessed part 210. The setting of the first recessed part 210 can prevent the middle part of the ingot base 11 from contacting the second material pad 200, prevent the ingot base 11 from tipping over, and improve the loading stability. The brazing plates 12 located on both sides of the ingot base 11 are abutted against the first material pad 100.

[0050] The aluminum alloy ingot loading tool disclosed in the embodiment of the utility model, the second material pad 200 is set to achieve the simultaneous support of the ingot base 11 and the brazing plate 12. The first material pad 100 supports the brazing plate 12, and the second material pad 200 supports the ingot base 11, so that the ingot base 11 and the brazing plate 12 maintain integrity, which can reduce the possibility of the ingot base 11 tipping over and reduce safety hazards. At the same time, it can reduce the relative movement of the ingot base 11 relative to the brazing plate 12, and improve the welding quality of the aluminum alloy ingot 10. The second material pad 200 can be disassembled and installed as needed. When loading conventional ingots, only the first material pad 100 can be used, such as Figure 6-Figure 7As shown, when loading LQ3 aluminum alloy ingots, the aluminum alloy ingot loading tooling disclosed in the embodiment of the utility model is used, that is, the first material pad 100 and the second material pad 200 are used in combination, which is flexible to use and has a wide range of applications.

[0051] In order to make the first support portion 220 have a better bearing effect on the ingot base 11, in some specific embodiments, such as Figure 8 and Fig.18 As shown, the cross section of the upper surface of the second material pad 200 is a V-shaped structure. It should be noted that the V-shaped structure here refers to the surfaces where the first support parts 220 on both sides extend and intersect, and the cross section is a V-shaped structure, such as Figure 8 The φ shown in refers to the angle of the V-shaped structure. Figure 13-Figure 15 As shown, the upper surface of the first support portion 220 matches the arc surface of the ingot base 11, so that both ends of the ingot base 11 abut against the first support portion 220, which can ensure the stability of loading and further reduce the possibility of the ingot base 11 tipping over.

[0052] In some specific embodiments, the extended surface of the supporting surface of the first supporting portion 220 is tangent to the arc surface of the ingot base 11, and the tangent point is located at 2 / 3 or above in the height direction of the ingot base 11. This setting method can ensure better support for the ingot base 11 and prevent the ingot base 11 from tipping over.

[0053] In some specific embodiments, Figure 5 and Fig.17 As shown, the first material pad 100 is provided with a groove 110. Figure 9-10 and Fig.18 As shown, the second material pad 200 is provided with a boss 230 that matches the groove 110. When installing, the boss 230 of the second material pad 200 is inserted into the groove of the first material pad 100. This method is convenient for disassembly and assembly. Figure 19-20 It is a schematic diagram of the structure after the two are assembled and assembled.

[0054] Based on the above embodiments, Figure 3 and Fig.17 As shown, the first material pad 100 includes a second recessed portion 120 and second supporting portions 130 located on both sides of the second recessed portion 120. The second recessed portion 120 extends along the length direction of the first material pad 100 (i.e. Fig.17 The second recessed portion 120 is arranged in parallel with the first recessed portion 210, as shown in the Y-axis direction. Fig.19 As shown, the groove 110 is along the width direction of the first material pad 100 (ie Fig.17 The second support portion 130 and the second recessed portion 120 are connected by the groove 110, and the number of the grooves 110 is two. Fig.10 and Fig.18 As shown, the boss 230 is arranged around the second material pad 200. During assembly, the boss 230 of the second material pad 200 is installed in the groove 110. The groove 110 can position the second material pad 200, and can further ensure the firmness of the assembly of the second material pad 200 and the first material pad 100. Figure 11-Figure 12 These are two views from different angles after the second material pad 200 and the first material pad 100 are assembled. Figure 13-Figure 14 It is a schematic diagram of loading an LQ3 aluminum alloy ingot on the aluminum alloy loading tool disclosed in an embodiment of the utility model.

[0055] like Fig.15 As shown, in some specific embodiments, the aluminum alloy ingot loading tool further includes an adjustment gasket 300, which is disposed in the groove 110 and between the first material pad 100 and the second material pad 200. In actual production, the size of the ingot matrix 11 is basically fixed, and the thickness of the brazing plate 12 may have various specifications according to different production processes. Various second material pads 200 of corresponding specifications to the brazing plate 12 may be manufactured according to actual production requirements, and the adjustment gasket 300 of appropriate thickness is added between the first material pad 100 and the second material pad 200 to adjust to meet the loading requirements.

[0056] The thickness of the brazing plate 12 includes four specifications: 20mm, 40mm, 60mm and 80mm. The second material pad 200 can be made according to these four specifications. For example, when the thickness of the brazing plate 12 is (20+a) mm, it is thicker than the 20mm thick brazing plate 12 by a thickness of a. At this time, the second material pad 200 corresponding to the 20mm thick brazing plate 12 is selected first, and then the adjustment gasket 300 is added between the second material pad 200 and the first material pad 100 to meet the loading requirements. Figure 15-16 As shown, the thickness of the gasket 300 is adjusted to b=a·tan[(180°-φ) / 2]=a·tan(90°-φ / 2), where φ is the V-angle of the first material pad 100 and a is the increased thickness of the brazing plate 12 .

[0057] For example, in a specific embodiment, the V-angle φ of the first material pad 100 is 136°, and the thickness of the adjustment pad 300 is b=a·tan(90°-136° / 2)=a·tan22°=0.404a, Fig.16 The β in the equation is 22°. When the thickness of the brazing plate 12 is of other specifications, the calculation method of the adjusting gasket 300 is the same as above. On the basis of the second material pad 200 of the above four specifications, adding an adjusting gasket 300 of appropriate thickness can meet the loading requirements of the brazing plate 12 with a thickness of 20mm-80mm. The adjusting gasket 300 is easy to process and can meet the installation requirements of brazing plates 12 of various specifications.

[0058] like Figure 3-Figure 5 and Fig.17 As shown, the aluminum alloy ingot loading tool disclosed in the embodiment of the utility model, the first material cushion 100 is provided with a support 140 and a support column 150, the support 140 is located at the bottom of the first material cushion 100, and plays a supporting role, and the support column 150 is arranged along the width direction (i.e. Fig.17 The support columns 150 are arranged in two numbers and are arranged on two second support parts 130 respectively. This arrangement can ensure the stability of the structure of the first material pad 100.

[0059] In some specific embodiments, Fig.18 As shown, the first recessed portion 210 and the first supporting portion 220 are transitioned through an arc surface.

[0060] In order to facilitate lifting, Figure 18-Figure 20 As shown, in some specific embodiments, a lifting eye hole 240 is opened on the upper surface of the second material pad 200. The number of the lifting eye holes 240 shown in the figure is two, and the specific number can be set according to the lifting requirements.

[0061] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
