A special-shaped aluminum groove production device

Abstract

The invention relates to a special-shaped aluminum groove production device. The special-shaped aluminum groove production device comprises conveying systems and further comprises a rolling system, acold equal-extrusion system, a tilted rolling system, a bending system, a strain stress relieving system and a glue sealing system which are sequentially arranged; and the conveying system is arrangedbetween the rolling system and the cold equal-extrusion system, and the conveying system is arranged between the tilted rolling system and the bending system. According to the special-shaped aluminumgroove production device, a special-shaped aluminum groove can be bent and can further be pre-machined, thus raw materials are more suitable for machining of the special-shaped aluminum groove, an aluminum strip is reinforced by fine grains through the cold equal-extrusion system, then the horizontal mechanical strength of the aluminum strip is improved macroscopically through the tilted rollingsystem, thus the finally-obtained special-shaped aluminum groove product is extremely high in overall all-directional mechanical strength, the overall performance of the product is unified and stable,and the using controllability of the product quality is improved greatly through the strain stress relieving system.

Description

technical field [0001] The invention relates to an aluminum trough production equipment, in particular to a special-shaped aluminum trough production device. Background technique [0002] With the rapid development of the country's overall industrial level and the forward-looking plan of Made in China 2025, China's transformation of traditional processing industries has become imminent. Among them, higher requirements are put forward especially for forming processing. The main requirement is that the forming process and the final products should have high added value instead of ordinary low-quality products. For example, the processed plates and strips need to be beautiful. The high specularity also needs to have various high-quality mechanical properties, so that it can be used and durable in various harsh environments. The channel material refers to a long strip material with a groove-shaped cross-section, which belongs to construction and mechanical materials. It is a pr...

Problems solved by technology

However, at present, there is very little research on the processing of special-shaped aluminum grooves, and a large number of products are in a low-quality state due to simple or even crude processing, which is not in line with the concept of industrial transformation advocated by the country.

[0004] At present, most of the devices for the production of special-shaped aluminum troughs have the following problems: (1) the current processing of special-shaped aluminum troughs is simply bending the aluminum strip without pre-processing it. The aluminum strip is pickled to remove impurities and rolled to improve the surface flatness, so that the aluminum strip with a lot of impurities and extremely low flatness is easy to be in the impurity area or undulate in the process of forming a special-shaped aluminum groove Metal folds are formed in the extremely high-density area, which is not only unsightly, but also directly leads to rapid aging, cracking and fracture of the special-shaped aluminum groove after being used for a long time or in harsh environments, and the cracking or fracture areas are all located in the above-mentioned metal fold area; ( 2) Most of the current special-shaped aluminum groove products have unstable internal structures, especially the grain size of the metal is not only extremely large but also very different, which will not only lead to extremely poor bonding force inside the metal, but also show isotropic mechanical strength in the macroscopic view At the same time, the overall performance of the product is inconsistent and unstable due to the large difference in grain size, which makes the product appear in a low-quality state and cannot be applied to various working conditions or conditions of use; (3) the current device Most of them use die extrusion bending, that is, the plate is fed into the mold with a gradually changing bending angle, and then the plate is processed into a special-shaped aluminum groove, but this processing method is easy to cause the mold to jam, especially in combination with the above problems , it is easy to be directly stuck in the mold due to the unevenness of the plate or the breakage during bending and forming

At the same time, such a processing size can only rely on the mold, and the effect of rapid customization cannot be achieved; (4) The current processing equipment rarely or never has a process of removing strain stress, regardless of the product itself. Strain stress is also the strain stress obtained during processing. Its large amount is easy to cause sudden explosion, that is, the product is suddenly damaged. For example, when the product is processed into a frame, its cutting and bending points are due to a large amount of strain. The release of stress makes it extremely fragile

(5) The current special-shaped aluminum groove products are rarely coated and put into use after they are produced. However, under long-term use conditions and harsh working conditions, there are no products that receive certain protection or cushioning The rate of aging and damage will be doubled, and the improvement of various properties obtained by processing it, such as the improvement of mechanical properties, will be reduced at a double rate, which is not only not conducive to the long-term use of the product, but also makes the replacement rate of the product extremely high. High, not only cumbersome but also will make the cost performance evaluation of the product in the market drop significantly
