Technical Field

[0001] The invention relates to the technical field of labor protection shoes, and in particular to a toe formula of labor protection shoes. Background Art

[0002] Labor protection shoes, also known as safety shoes, are security products. The toe of labor protection shoes has the function of preventing objects from hitting the foot and toes. Traditional labor protection shoes are generally made of steel inner toe. As people's demand for light and comfortable labor protection shoes increases, bulky steel toe is no longer the first choice. Therefore, an aluminum alloy formula suitable for the toe of labor protection shoes is proposed. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a toe formula of a labor protection shoe in view of the deficiencies of the above-mentioned prior art.

[0004] To achieve the above object, the present invention provides the following technical solution: a toe cap formula of a labor protection shoe, composed of the following components by weight percentage: 84.75% to 85.01% aluminum, 8.58% to 8.96% silicon, 0.881% to 1.03% iron, 3.40% to 3.51% copper, 0.187% to 0.239% manganese, 0.0346% to 0.0352% magnesium, 0.0626% to 0.0852% chromium, 0.0595% to 0.0602% nickel, 1.26% to 1.27% zinc, 0.0964% to 0.102% titanium, 0.0021% silver, 0.00072% to 0.0010% boron, 0.00040% to 0.00047% beryllium, and 0.0032% bismuth. ~0.0035%, calcium 0.0018%~0.0025%, gallium 0.0144%~0.0145%, molybdenum 0.00071%~0.00092%, lead 0.0459%~0.0478%, antimony 0.0438%~0.0531%, tin 0.0318%~0.0324%, vanadium 0.0113%~0.0140%, zirconium 0.0051%~0.0052%, hafnium 0.0135%~0.0198%, yttrium 0.0031%~0.0034%, cadmium and cobalt are both less than 0.001%, cerium is less than 0.0015%, lanthanum is less than 0.0003%, lithium is less than 0.0002%, sodium and strontium are both less than 0.0001%, and scandium is less than 0.0005%.

[0005] The present invention is further configured to be composed of the following components by weight percentage: 84.91% aluminum, 8.76% silicon, 0.948% iron, 3.45% copper, 0.211% manganese, 0.0349% magnesium, 0.0727% chromium, 0.0598% nickel, 1.26% zinc, 0.0994% titanium, 0.0021% silver, 0.00084% boron, 0.00043% beryllium, 0.0034% bismuth, and 0.0022% calcium. , gallium 0.0144%, molybdenum 0.00078%, lead 0.0469%, antimony 0.0469%, tin 0.0321%, vanadium 0.0125%, zirconium 0.0052%, hafnium 0.0167%, yttrium 0.0033%, cadmium and cobalt both less than 0.001%, cerium less than 0.0015%, lanthanum less than 0.0003%, lithium less than 0.0002%, sodium and strontium both less than 0.0001%, scandium less than 0.0005%.

[0006] The present invention with the above characteristics: uses lightweight metal aluminum as the main component, provides high strength and rigidity while reducing the weight of the toe, improves wearing comfort and reduces the burden on workers; adds silicon to the formula to enhance the strength, hardness and chemical corrosion resistance of the toe; adds copper, manganese, magnesium and other elements to the formula to improve the toughness of the aluminum alloy, so that the toe is not easily deformed or broken when impacted; adds chromium and nickel elements to the formula to improve the corrosion resistance of the material and extend the service life of the toe; adds titanium to the formula to improve the high temperature resistance of the toe; adds boron, beryllium, bismuth and other trace elements to the formula , and can also improve the wear resistance, heat resistance and corrosion resistance of the toe cap; adding vanadium, zirconium, hafnium and yttrium rare earth elements to the formula can improve the high temperature resistance and strength of the material; the content of cadmium, cobalt, cerium, lanthanum, lithium, sodium, strontium and scandium is controlled to a very low level, which can ensure the environmental protection of the labor protection shoes and the protection of workers' health; using the characteristics of aluminum alloy products themselves, the components are scientifically proportioned to optimize the performance of the aluminum alloy, so that the aluminum alloy toe cap of the labor protection shoes produced fully meets the relevant international standards in terms of compressive strength, while reducing its own weight, giving the wearer a comfortable wearing experience while getting safety protection.
