Problems solved by technology

[0003] At present, the aluminum alloy handles commonly used in the market are mainly simple straight lines or "]" shapes, which are not aesthetically pleasing, especially for household refrigerators with certain artistic shapes, and straight line handles cannot meet the aesthetic needs of users; although there are manufacturers Some curved handles are produced, but due to the technical problems such as extrusion marks on the surface of the aluminum substrate, bending and forming, etc. during the processing process, the aluminum alloy handles produced by these manufacturers are low in yield and efficiency, and the overall cost high

Embodiment 1

[0027] The aluminum alloy handle of the refrigerator is taken as an example to illustrate the manufacturing process of the aluminum alloy handle.

[0028] (1) Melting and casting refining: put aluminum ingots into the melting furnace for smelting, add aluminum-silicon master alloy, magnesium ingot, aluminum-titanium-boron wire, refining agent and slag-removing agent during the smelting process, and pass through the rotating degassing treatment pool The graphite rotor chops the chlorine and argon blown into the aluminum alloy melt to form a large number of dispersed bubbles, so that the aluminum alloy liquid and chlorine and argon fully contact in the treatment pool. According to the principle of air pressure difference and surface adsorption, the bubbles The body absorbs the hydrogen in the melt, and after absorbing the oxidized slag, it rises to the surface of the melt to form scum.

[0029] (2) Extrusion: Before extrusion, use a peeling machine to remove the 6mm scale and im...

Embodiment 2

[0035] The aluminum alloy handle of the freezer is taken as an example to illustrate the manufacturing process of the aluminum alloy handle.

[0036] (1) Melting and casting refining: put aluminum ingots into the melting furnace for smelting, add aluminum-silicon master alloy, magnesium ingot, aluminum-titanium-boron wire, refining agent and slag-removing agent during the smelting process, and pass through the rotating degassing treatment pool The graphite rotor chops the chlorine and argon blown into the aluminum alloy melt, forming a large number of diffuse bubbles, so that the aluminum alloy liquid and chlorine and argon fully contact in the treatment pool. According to the principle of air pressure difference and surface adsorption, the bubbles The body absorbs the hydrogen in the melt, and after absorbing the oxidized slag, it rises to the surface of the melt to form scum.

[0037] (2) Extrusion: Before extrusion, use a peeling machine to remove the 8mm scale and impurity...

Embodiment 3

[0043] The aluminum alloy handle of the microwave oven is taken as an example to illustrate the manufacturing process of the aluminum alloy handle.

[0044] (1) Melting and casting refining: put aluminum ingots into the melting furnace for smelting, add aluminum-silicon master alloy, magnesium ingot, aluminum-titanium-boron wire, refining agent and slag-removing agent during the smelting process, and pass through the rotating degassing treatment pool The graphite rotor chops the chlorine and argon blown into the aluminum alloy melt, forming a large number of diffuse bubbles, so that the aluminum alloy liquid and chlorine and argon fully contact in the treatment pool. According to the principle of air pressure difference and surface adsorption, the bubbles The body absorbs the hydrogen in the melt, and after absorbing the oxidized slag, it rises to the surface of the melt to form scum.

[0045] (2) Extrusion: Before extrusion, use a peeling machine to remove the 10mm scale and ...

Abstract

The invention relates to a method for manufacturing an aluminum alloy handle. The method is technologically characterized by including the steps of casting, refinement, extrusion, saw cutting, pattern brushing, machining, surface treatment, packaging, storage and others. The aluminum alloy handle has the advantages of being high in strength, resistant to corrosion, abrasion and collision, beautiful in appearance, luxurious, gorgeous, high in finished product rate, low in comprehensive cost and the like, and the method is applied to door handles of a refrigerator, a freezer, a microwave oven and other household appliances.

Description

technical field [0001] The invention relates to the field of aluminum alloy processing, in particular to a method for manufacturing an aluminum alloy handle for household appliances. Background technique [0002] The door handles of traditional refrigerators, freezers, microwave ovens and other home appliances are mainly pure plastic components, stainless steel or copper components, aluminum alloy and plastic composite components, etc. Pure plastic components are not strong enough, easy to age, and easy to deform at high temperatures; stainless steel or copper components Materials are in short supply and production costs are high; aluminum alloy and plastic composite components need to be connected or the strength of the adhesive should be good to ensure the service life. The aluminum alloy handle has the characteristics of fashionable appearance design, beautiful and luxurious appearance, strong metallic feeling on the surface, colorful coating colors, smooth and graceful s...
