Problems solved by technology

At present, there are two kinds of pre-aging processes widely used by enterprises: (1) under the condition of temperature less than 100 ℃, carry out long-term heat preservation, that is, pre-aging at (60-100) ℃ / (2-25) h after solid solution Aging treatment; its main disadvantage is the use of a pre-aging process of heat preservation at less than 100°C. In order to ensure the uniformity and performance consistency of the plates in the mass production process, the heat preservation time should be at least 2 hours according to the size of the plates. The economic cost is high and the production low efficiency
(2) At a temperature greater than 140°C, heat preservation for a short time, that is, pre-aging treatment at (140-240)°C / (5-15)min after solid solution, the disadvantage of using pre-aging at a temperature greater than 140°C Although the heat preservation time is only about 10 minutes, it can only be produced in a small amount of a single piece, and the uniformity and performance consistency of the plate cannot be guaranteed during mass production

Abstract

The invention provides a production process of an aluminum alloy medium heavy plate applied to a back plate of a tablet personal computer, and belongs to the technical field of aluminum alloy sheet processing. The production process of the aluminum alloy medium heavy plate applied to the back plate of the tablet personal computer comprises the steps of placing an aluminum alloy sheet into a solidsolution heat treatment furnace, keeping warm at the temperature being 530 to 540 DEG C for 8 to 15min, water cooling, putting the water-cooled aluminum alloy sheet into an air resistance furnace withthe temperature being 200 to 300 DEG C within 3h, carrying out pre-ageing treatment, taking the aluminum alloy sheet out when the temperature of the aluminum alloy sheet reaches to 120 to 140 DEG C,using a fan for blow-cooling the aluminum alloy sheet to the temperature being below 60 DEG C, detecting after cooling, and obtaining a finished product. The aluminum alloy medium heavy plate preparedthrough the production process provided by the invention is applied to the back plate of the tablet personal computer, and has a favorable stamping ability and a favorable mechanical performance, meanwhile, the production efficiency is improved, the production cost is reduced, and the sheet uniformity and the performance consistency are ensured.

Description

【Technical field】 [0001] The invention relates to the technical field of aluminum alloy plate processing, in particular to a production process of an aluminum alloy medium-thick plate applied to the back plate of a tablet computer. [0002] 【technical background】 [0003] Tablet computer backplanes mainly include aluminum alloy, plastic, and glass. Due to the excellent characteristics of aluminum alloy shells such as high strength, excellent surface texture, and good thermal conductivity, aluminum alloys are widely used in tablet computer backplanes. Among them, 6463 series aluminum The alloy shell has the advantages of high strength and hardness, good oxidation texture and bright metallic luster. However, the natural aging hardness of 6463 aluminum alloy increases after solution quenching, which will lead to bad losses such as stamping cracking and machining deformation. [0004] In order to ensure that the 6463 aluminum alloy sheet used by customers has stable stamping and...
