Manufacturing process of 6a02t6 container profiles

Abstract

The invention relates to a production process of 6A02T6 container sections. The production process includes the steps: (1), preparing; (2), heating cast rods in graded manner; (3), performing heat treatment to an extruding barrel and a die respectively; (4), extruding to be formed; (5), quenching on a production line; (6), stretching and leveling; (7), treating manually; (8), cutting finished products; and (9), packaging to be stored. During a production process, surfaces and forming conditions of the sections are detected at any time. The production process has the advantages that after extruding forming, quenching on the production line, stretching and treating manually, strength of extension of the sections is > / =240MPa, elongation rate is > / =8%, and Vickers hardness number is > / =14Hw, overall performance of the sections is good, and the finished container sections are high in strength and long in service life; surfaces of the sections are high; aluminum sections can be formed rapidly after being quenched on the production line, deformation amount of the finished sections is small, section rejection rate is low; and the production process is simple.

Description

Technical field [0001] The invention relates to a process for processing aluminum alloy profiles, in particular to a process for manufacturing 6A02T6 container profiles. Background technique [0002] A container refers to a large-scale cargo container with a certain strength, rigidity and specification for turnover. Using containers to transfer goods can be directly loaded in the consignor’s warehouse and transported to the consignee’s warehouse for unloading. There is no need to remove the goods from the container when changing vehicles or ships in the middle. The container installation and manufacturing materials can be divided into: steel containers, aluminum alloy containers and FRP containers. Among them, the steel container is made of the main material just now. Its advantages are high strength, reliable structure, and high welding performance. However, the density of steel is relatively large, and the volume of the container is generally very large, making the overall qua...

AI Technical Summary

Problems solved by technology

Among them, the steel container is made of steel as the main material, which has the advantages of high strength, reliable structure, and high welding performance. However, the density of steel is relatively high, and the volume of the container is generally very large, which makes the overall mass of the container large and easy to handle. Difficult, and the corrosion resistance of steel containers is poor, exposed to the air for a long time, the surface of the container is corroded, and the service life is greatly reduced; FRP containers are made of FRP as the main material, which has the advantages of high strength, good rigidity, heat insulation, Anti-corrosion and chemical resistance are good, but its weight is still large, and it is easy to age, the joint strength is low, and the maintenance cost is high; aluminum alloy containers are made of aluminum alloy profiles, and traditional aluminum alloy containers are light in weight. , beautiful appearance, good anti-corrosion performance and other advantages, it has become the main material in the container manufacturing industry, but its high cost, poor welding performance and easy deformation of the aluminum alloy box limit the development of aluminum alloy profiles in the container manufacturing industry. For large containers , the aluminum alloy material can no longer meet its strength requirements

In addition, the traditional aluminum profile processing technology adopts natural cooling after extrusion molding, which leads to large deformation of the profile and increases the probability of waste products
