Aluminum alloy toolbox is one of the products of aluminum box products. It is a kind of box that is formed by aluminum alloy material to achieve the application of placing tools and measuring tools. Different from other toolboxes, this toolbox has aluminum alloy. The characteristics of the material are light weight, easy to process, and have incomparable advantages over other materials in terms of strength.
Aluminum cases, aluminum alloy tool boxes, aluminum alloy packaging boxes, medical boxes, display boxes and other aluminum product packaging boxes, Yuhang Chassis Factory products include: cosmetic cases, jewelry cases, CD cases, chip cases, Document password box, beauty salon box, medical care box, precision instrument box, laptop box, clock box, tool box, flight box, photographic equipment box, performance prop box, musical instrument box, billiard club box, golf suit box, bank cash box , Cash box, barbecue box, wine box, fishing gear box, gift box, acrylic box, various shockproof liners, etc.
The main body of the product is made of high-quality aluminum alloy profiles, which have the characteristics of reasonable design, strong structure and beautiful appearance. It is widely used in instruments, meters, electronics, communications, automation, sensors, smart cards, industrial control, precision machinery and other industries. It is a high-end instrumentation The ideal cabinet.
Aluminum box [aluminum alloy tool box] welding
(1) Choose welding wire
Generally choose 301 pure aluminum welding wire and 311 aluminum silicon welding wire.
(2) Select welding method and parameters
It is generally carried out by the left welding method, and the welding torch and the workpiece form an angle of 60°. When the welding thickness is more than 15mm, the right welding method is used, and the welding torch and the workpiece form a 90° angle.
(3) Preparation before welding
Use chemical or mechanical methods to strictly clean the surface oxide film on both sides of the weld groove.
Mechanical cleaning can use wind or electric milling cutters, scrapers, files and other tools. For thinner oxide films, 0.25mm copper wire brushes can also be used to remove oxide films.
Welding is performed immediately after cleaning. If the storage time exceeds 4 hours, it should be cleaned again.
(4) Features of aluminum and aluminum alloy materials in aluminum boxes
Aluminum is a silver-white light metal with good plasticity, high electrical and thermal conductivity, and also has the ability to resist oxidation and corrosion. Aluminum is easily oxidized to produce aluminum oxide film, which is easy to produce inclusions in the weld, thereby destroying the continuity and uniformity of the metal, reducing its mechanical properties and corrosion resistance.
(5) Difficulties in welding aluminum and aluminum alloy materials in aluminum boxes
Very easy to oxidize. In the air, aluminum is easily combined with oxidation to form a dense aluminum oxide film (thickness of about 0.1-0.2 μm), with a high melting point (about 2050°C), far exceeding the melting point of aluminum and aluminum alloys (about 600 ℃). The density of aluminum oxide is 3.95-4.10g/cm3, which is about 1.4 times that of aluminum. The surface of aluminum oxide film is easy to absorb moisture. When welding, it hinders the fusion of basic metals, and it is easy to form pores, slag, and Defects such as lack of fusion, causing degradation of weld performance.
Aluminum alloy is made of pure aluminum by adding some alloying elements, such as aluminum-copper alloy, aluminum-zinc-magnesium-copper super hard aluminum alloy. Aluminum alloy has the characteristics of light weight, low cost, mechanical properties (uniform force), and aluminum alloy is easy to process and has a high degree of heat dissipation. Especially the engine part of the vehicle is particularly suitable for the use of aluminum alloy materials. As for most computer cases, aluminum-copper alloys are used. Mainly consider heat dissipation. Because copper and aluminum are mixed and extruded, the heat dissipation performance is quite good, and even some high-end CPU water cooling fans use this material. A kind of box body using aluminum alloy extruded material and related accessories. Different from other profile boxes, this aluminum profile box has the characteristics of aluminum alloy material, light weight, easy processing, strong load-bearing capacity, beautiful appearance, and reasonable design structure. Due to the unique characteristics of the aluminum profile box and the higher and higher technological content, it plays a better role in protecting the product in terms of convenient transportation and use, and is an ideal box for various high-end products.
