The invention discloses a high-strength and high-toughness light aluminum alloy anti-collision beam and a machining process thereof, relates to the technical field of aluminum alloy anti-collision beam material treatment, and aims to solve the problems that when an anti-collision beam is prepared from a low-standard aluminum alloy material, the overall strength and toughness are poor, and when an anti-collision beam is prepared from a high-strength aluminum alloy material, the overall strength and toughness are poor. And the difficulty of the whole processing technology is high. The double-layer stamping C-shaped anti-collision beam is composed of the first aluminum alloy arm, the reinforcing ribs and the second aluminum alloy arm, meanwhile, the first aluminum alloy arm and the second aluminum alloy arm which are supported front and back are made of different types of aluminum alloy materials, the overall stability is improved, and meanwhile the manufacturing cost of the overall anti-collision beam is reduced; and meanwhile, reinforcing ribs are inserted between the first aluminum alloy arm and the second aluminum alloy arm in a penetrating mode, the second aluminum alloy arm subjected to high-strength fine treatment is adopted for supporting, the toughness and strength of the whole anti-collision beam are improved, and compared with a traditional open type C-shaped anti-collision beam, the overall stability, strength and bending resistance are further improved.

    本发明公开了一种高强度高韧性的轻质铝合金防撞梁及其加工工艺,涉及铝合金防撞梁材料处理技术领域,用于解决采用低标准铝合金材质制备防撞梁时,其整体强度和韧性较差,而采用高强度铝合金材质制备防撞梁时,整体加工工艺难度高的问题;本发明是通过铝合金臂一、加强筋和铝合金臂二组成双层冲压C型防撞梁,同时前撑后支的铝合金臂一与铝合金臂二采用不同型号铝合金材质,提升整体稳定性的同时降低整体防撞梁造价,同时在铝合金臂一与铝合金臂二之间穿插加强筋以及采用高强度细小处理的铝合金臂二支撑,提高整个防撞梁的韧性和强度,相比较传统开放式C型防撞梁,整体稳定性、强度和抗弯能力均得到进一步提升。
