[0054] Si 0.20%~0.80%;

[0055] Zr 0.2%~0.3%;

[0056] Ti 0.10%~0.2%;

[0057] Cu 3.5%~4.5%;

[0058] The balance of Al;

[0059] b) homogenizing, planing, sawing and milling the aluminum alloy ingot;

[0060] c) hot-rolling and cold-rolling the milled aluminum alloy ingot;

[0061] d) Annealing the cold-rolled aluminum alloy prefabricated plate;

[0062] e) pre-shearing and finishing the annealed aluminum alloy prefabricated panel;

[0063] f) Cleaning and drying the finished aluminum alloy prefabricated plate to obtain an aluminum alloy plate for the toe cap of labor insurance leather shoes.

[0064] According to the present inven...

Abstract

The invention provides an aluminium alloy sheet material for labour protection leather shoes head and preparation method thereof, and the aluminium alloy sheet material is 7xxx series aluminium alloy, and concretely comprises the following components by weight percent: 0.50-1% of Fe, 0.40-1.0% of Mn, 0.4-0.80% of Mg, 0.20-0.80% of Si, 0.2-0.3% of Zr, 0.10-0.2% of Ti, 3.5-4.5% of Cu and Al the rest amount. The aluminium alloy contains Zr, Ti, Si, Cu and Mg, and has a high hardness and intensity, and belongs to the superhard aluminium alloy, the invention has a good wear resistance, and after the stress is relieved by processing, the product does not deform and warp, thereby shortening the moulding time and improving the work efficiency. The aluminium alloy sheet material provided by the invention can satisfy the requirements of intensity and hardness, and ensure the thickness of the aluminium alloy sheet material is the lowest.

Description

technical field [0001] The invention relates to the field of preparation of aluminum alloys, in particular to a preparation method of an aluminum alloy plate used for labor protection leather toe caps. Background technique [0002] Labor insurance shoes are a kind of shoes that have a safety protection effect on the feet. There are many types of it, such as toe protection, anti-puncture, insulation, acid and alkali resistance, etc. The selection of labor insurance shoes should be carried out according to the nature and degree of hazards of the working environment. [0003] General labor insurance shoes have fixed plates or protective plates embedded in their heads, and the fixed plates or protective plates use aluminum alloy plates or plastic plates, but the aluminum alloy plates used for safety protection of labor insurance shoes in the prior art, The thickness is thicker, and the performance cannot meet the requirements. Contents of the invention [0004] The technica...
