Aluminum alloy extrusion is an indispensable material for modern industry, which is widely used in electrical appliances, construction, automobiles, aviation, ships, rail transit and other fields. It has excellent physical and chemical properties such as light weight, high strength, corrosion resistance and good thermal conductivity, especially suitable for high strength, light weight and high corrosion resistance. So, how is it produced? How to determine the difficulty of the section? Let's introduce the relevant knowledge.
First of all, the production method of aluminum alloy extrusion is realized by aluminum profile extrusion processing. Extrusion is a processing method in which aluminum profile bar stock is deformed into the desired shape by special mold extrusion. Its advantage is that it can make a variety of irregular cross-sectional shapes, which can realize mass production, and it also has high economy. Its extrusion production process is: put the aluminum profile bar stock into the hopper of the extruder, load the mold on the extruder, start the extruder, and extrude the aluminum profile out. For aluminum extrusion processing, factors such as extrusion temperature, extrusion speed, extrusion strength, and extrusion head design are important factors affecting the quality of aluminum profiles and need to be carefully controlled.
Secondly, for the problem of determining the difficulty of the section, we need to consider the following aspects:
1. The wall thickness and shape of the profile: Usually the shape of the section of the aluminum alloy profile is changeable, some are rectangular, some are round, and there are other special-shaped section shapes, but regardless of the cross-sectional shape, the overall strength and rigidity of the aluminum profile must be guaranteed. Therefore, in the design and production of aluminum profiles, it is necessary to fully consider its shape and thickness to ensure that it can withstand strong forces and pressures.
2. Cross-section quality: The cross-sectional quality of aluminum alloy profiles is directly related to its service life and load capacity and other issues, so the quality of the profile should be ensured in the production process, and some unqualified aluminum profiles should be removed in time during the production process to ensure the quality of the product.
3. Machining and surface treatment: Aluminum profiles often require a series of machining and surface treatment in the production process, which also has a certain impact on the determination of the difficulty of profile sections. Therefore, the quality of machining and surface treatment has also become an important factor to pay attention to in the process of determining the difficulty of the section.
In short, the production method of aluminum alloy extrusion is realized by aluminum profile extrusion processing, and its production process needs to carefully control the extrusion temperature, extrusion speed, extrusion strength, extrusion head design and other factors. The determination of section difficulty needs to be considered from the wall thickness and shape of the profile, section quality, machining and surface treatment to ensure that the produced aluminum alloy profile meets the requirements and meets the actual application needs.
