The invention relates to the technical field of scooters, in particular to a preparation method of an aluminum alloy casting for a forehead, the aluminum alloy casting and the forehead. The preparation method of the aluminum alloy casting for the forehead comprises the steps of die casting blank preparation, high-temperature aging heat treatment and surface coating treatment. According to the preparation method of the aluminum alloy casting, the solid solution procedure can be omitted, the preparation method can be completed only through the three steps of die casting, failure treatment and surface coating treatment, the procedures are omitted, the production efficiency is improved, and the production cost is reduced. Meanwhile, due to the fact that the temperature of the solid solution process is too high, the surface of the casting is prone to generating bubble defects, and therefore the solid solution process is saved, and the good surface quality and strength effect can be achieved. According to the aluminum alloy casting, the Cu content is increased, so that the effect of improving the strength and toughness of the material is achieved. The forehead is manufactured through the aluminum alloy casting obtained through the manufacturing method, and therefore the structural strength and toughness of the forehead are improved.

    本发明涉及滑板车技术领域,尤其涉及一种额头所用的铝合金铸件的制备方法、铝合金铸件及额头。该额头所用的铝合金铸件的制备方法包括:制备压铸件坯料,高温时效热处理,以及表面涂装处理。该铝合金铸件制备方法能够节省固溶工序,仅通过压铸、失效处理以及表面涂装处理三个步骤即可完成,该工序实现了节省工序,提高生产效率,且有利于降低生产成本。同时也因固溶工艺温度过高,使铸件表面容易产生气泡缺陷,因此本实施例节约固溶工艺,有利于满足较好的表面质量和强度效果。该铝合金铸件通过提高Cu含量,以达到提高材料的强度和韧性的效果。该额头通过上述制备方法得到的铝合金铸件制得,从而提高额头的结构强度和韧性。
