Aluminum alloy material for safety shoes and production method thereof

Abstract

The invention discloses an aluminum alloy material for a safety shoe. The aluminum alloy material comprises following components including, by weight percent, smaller than or equal to 0.15% of Si, smaller than or equal to 0.30% of Fe, 0.01%-0.10% of Cu, 0.03%-0.18% of Mn, 0.08%-1.8% of Mg, 0.05%-0.14% of Cr, 3.0%-6.0% of Zn 0.02%-0.05% of Ti, 0.05%-0.20% of Zr and the balance Al. The above raw materials are adopted to be subjected to smelting, casting, homogenization treatment, hot rolling, cold rolling, cleaning, solid solution quenching, artificial aging and the like, the aluminum alloy is prepared and obtained. The produced aluminum alloy material is directly punched and formed at a time, heat treatment does not need to be additionally conducted, the production period is shortened, andthe production cost is reduced. In conclusion, the forming performance of an aluminum toe cap is improved, the shoe making factory cost is reduced, the yield during punching is increased, and the requirement for the aluminum alloy material for the safety shoe is met.

Description

technical field [0001] The invention relates to an aluminum alloy material and a production method thereof, in particular to an aluminum alloy material for safety shoes and a production method thereof. Background technique [0002] At present, personnel in some special working environments such as firefighting, construction sites, and industrial production workshops often encounter heavy objects such as falling metals and injure their insteps and toes during their work. Therefore, staff in these industries There are certain requirements for the toe part. The application with the publication number CN106418876A discloses a production process of safety shoes with steel toe caps. However, the toe caps are heavy and increase the overall weight of the safety shoes. The strength affects work efficiency, and also reduces the comfort of wearing, which brings inconvenience to work. In addition, due to the limitations of the manufacturing process, the peripheral parts of the safety ...

AI Technical Summary

Problems solved by technology

At present, the prior art has the following disadvantages: 1. When shoe manufacturers adopt aluminum alloy materials to produce toe caps, punching is easy to crack, especially in figure 2 The middle edge is easy to crack; 2. After the shoe manufacturer receives the aluminum alloy material and stamps it, in order to improve the strength of the toe cap, heat treatment is required, which increases the production cycle and costs. If no heat treatment is performed, the strength of the toe cap will be low. It cannot meet the safety requirements of the toe cap; 3. During the stamping process of the shoe manufacturer, it needs to be punched first figure 1 The shape of the number 1 in the figure, and then bend it to make a downward sloping edge, which obviously increases the process flow; 4. When producing such aluminum alloy materials by conventional processes, the uniformity of the material properties of the same batch is low. Leading to lower yield of shoe manufacturers
