Embodiment 1

[0050] like figure 1 As shown, it is a schematic structural diagram of a high-strength, lightweight aluminum alloy door and window frame in a preferred embodiment of the present invention. The aluminum alloy doors and windows in this embodiment are mainly assembled and connected between the horizontal frame 100 and the vertical frame 200 in sequence. Formed, the horizontal frame 100 and the vertical frame 200 are all aluminum alloy profiles, which are convenient for assembly. The horizontal frame 100 and the vertical frame 200 realize quick disassembly and assembly, and improve production efficiency.

[0051] like figure 2 as well as image 3 As shown, the horizontal frame 100 is a hollow structure with an opening on one side, and an assembly groove 10 is arranged in the horizontal frame 100, and the assembly groove 10 is used to assemble the vertical frame 200. In this embodiment, the One end of the vertical frame 200 connected to the horizontal frame 100 is fixedly connec...

Embodiment 2

[0063] In this example, the components and preparation method of the high-temperature liquid aluminum alloy liquid in Example 1 are also provided, and the high-temperature industrial aluminum alloy includes the following components: by weight percentage:

[0064] Zn: 13.8%, Mg: 4.2%, Cu: 3.7%, Li: 2.1%, Si: 1.8%, and the balance is Al;

[0065] Raise the temperature of Al in the above materials to 700-800°C. At this time, the Al material is completely melted, and then add the remaining materials to the molten Al liquid, and raise the temperature to 900-1100°C. At this time, the high-temperature liquid aluminum alloy MgZn will be precipitated in the liquid 2 strengthening phase and CuAl 2 Strengthening phase, thereby improving the strength of the aluminum alloy material, the aluminum alloy material has higher strength after cooling and forming, and improves the material performance.

Embodiment 3

[0067] In this example, the components and preparation method of the high-temperature liquid aluminum alloy liquid in Example 1 are also provided, and the high-temperature industrial aluminum alloy includes the following components: by weight percentage:

[0068] Zn: 14.7%, Mg: 5.2%, Cu: 4.3%, Li: 2.8%, Si: 1.5%, and the balance is Al;

[0069] Raise the temperature of Al in the above materials to 700-800°C. At this time, the Al material is completely melted, and then add the remaining materials to the molten Al liquid, and raise the temperature to 900-1100°C. At this time, the high-temperature liquid aluminum alloy MgZn will be precipitated in the liquid 2 strengthening phase and CuAl 2 Strengthening phase, thereby improving the strength of the aluminum alloy material, the aluminum alloy material has higher strength after cooling and forming, and improves the material performance.

Abstract

The invention discloses a high-strength and light aluminum alloy door and window frame. The high-strength and light aluminum alloy door and window frame is formed by sequentially assembling and connecting a transverse frame and a vertical frame, an assembling groove is formed in the transverse frame, a fixing base is fixedly connected to the end, connected with the transverse frame, of the vertical frame, a connecting sliding groove is formed in the lower portion of the side wall of the vertical frame, the transverse frame is further provided with a fixing sliding groove, and the fixing base at the bottom of the vertical frame is assembled in the fixing sliding groove in the transverse frame. The aluminum alloy door and window frame is high in stability after being assembled. In addition, the invention further discloses a preparation process of the aluminum alloy door and window frame. A MgZn2 strengthening phase and a CuAl2 strengthening phase are formed in an alloy material, so that the strength of the alloy material is greatly improved, and the design requirement of the material is met.

Description

technical field [0001] The technical field of aluminum alloy profiles of the present invention, in particular, relates to a high-strength, lightweight aluminum alloy door and window frame and its preparation process. Background technique [0002] Aluminum alloy profile is a kind of metal material, which is widely used in industry, daily use and other fields. Due to its low density and light texture, aluminum alloy profile can be processed into target devices according to needs, such as door and window frames, etc., and is widely used. [0003] In the process of production and processing, the existing aluminum alloy materials are processed into various types of profiles, and door and window frames are produced through the process of assembling between profiles, etc. However, the existing aluminum alloy profiles still exist after being processed into door and window frames. The following defects: [0004] In order to facilitate the assembly of aluminum alloy profiles, differe...
