Problems solved by technology
[0016] In the existing production method, after quenching, there is a large residual stress inside the aluminum alloy sheet, and straightening can only eliminate part of it. After aging, the residual stress inside the aluminum alloy sheet still exists, and the residual stress is relatively large. The distribution of residual stress changes during cutting, which is easy to cause warping of the aluminum alloy sheet, and finally makes the unevenne

Embodiment Construction
[0043] Please refer to the attached figure 1 , figure 1 It is a schematic flow diagram of Embodiment 1 of the cutting method for crystalline silicon wafers provided by the embodiment of the present invention, and the specific method is as follows:
[0044] S101) Quenching:
[0045] Heating the aluminum alloy plate, after heating for a set time, take the aluminum alloy plate out of the heating medium, and then immediately immerse the aluminum alloy plate in water to cool it, so as to improve the mechanical properties of the aluminum alloy plate;
[0046] S102) Straightening for the first time:
[0047] Use a multi-roller straightening machine to straighten the cooled aluminum alloy sheet for the first time, reduce the residual stress inside the aluminum alloy sheet, and straighten the aluminum alloy sheet;
[0048] S103) aging treatment:
[0049] Insulate the aluminum alloy plate, the heat preservation time is the set time, harden the aluminum alloy plate, and improve the s...

The invention provides a production method for an aluminum alloy plate. The production method includes the steps that the aluminum alloy plate is heated, and after heating is conducted for the set time, the aluminum alloy plate is taken out from a heating medium and then is immediately immersed in water to be cooled; a multi-roller straightening machine is used for conducting the first time of straightening on the cooled aluminum alloy plate; heat preservation is conducted on the aluminum alloy plate, and the heat preservation time is the set time; a multi-roller straightening machine is used for conducting the second time of straightening on the aluminum alloy plate; the aluminum alloy plate obtained after the second time of straightening is sawn, and a finished aluminum alloy plate is formed. By means of the above production method for the aluminum alloy plate, the second-time straightening process is added on the basis of an existing production technology, residual stress in the aluminum alloy plate is reduced through the second-time straightening process, residual stress distribution little changes during sawing, warping of the aluminum alloy plate is not likely to be caused, unevenness of the aluminum alloy plate is reduced, and therefore the use requirement for low unevenness of the aluminum alloy plate used for an aviation container is met.
Description
technical field [0001] The invention relates to the technical field of air container manufacturing, and more specifically, relates to a production method of an aluminum alloy plate. [0002] technical background [0003] With the continuous development of the aviation industry, the requirements for air containers used to ship goods are also gradually increasing. [0004] At present, air containers are made of special aluminum alloy plates, which are composed of 0.25 parts of Si (silicon), 0.40 parts of Fe (iron), 0.25 parts of Cu (copper), 0.10 parts of Mn (manganese), 0.05 parts Cr (chromium), 0.10 parts of Ti (titanium), 0.13 parts of Zr (zirconium), 1.5 parts of Mg (magnesium), 5.50 parts of Zn (zinc) and the balance of Al (aluminum). [0005] The technical scheme adopted in the present invention is: [0006] The invention is composed of a solid silicone tube, metal guide probes respectively connected to both ends of the solid silicone tube and a hollow silicone sleeve s...
