The invention belongs to the technical field of automobile bumpers, and provides a production method of a foamed aluminum automobile bumper, the foamed aluminum automobile bumper comprises an anti-bending metal cross beam, an outer cover plate, a U-shaped lining piece shell and a plurality of groups of reinforcing ribs, the reinforcing ribs are fixed in the lining piece shell, a foamed aluminum filling material is assembled in the lining piece shell in a close fit manner, and meanwhile, a buffer energy absorption layer and an energy absorption box are further arranged; by means of the gradient structure of the buffering energy absorption layer, energy can be absorbed step by step when the automobile is impacted, the energy absorption efficiency can be maximized, and the impact on passengers is reduced; the inducing groove formed in the side wall of the energy absorption box is used for guiding a deformation mode, and the collision force peak value is effectively reduced; the inner pipe and the outer pipe are connected through the high-strength adhesive, connection stability is guaranteed when the bumper is impacted, separation or damage of the connecting position is avoided, and the overall reliability of the bumper is improved.

    本发明属于汽车保险杠技术领域,提供了一种泡沫铝汽车保险杠的生产方法,包括抗弯金属横梁、外盖板、U形的内衬件壳体以及多组加强筋,所述内衬件壳体中固定加强筋,并紧密配合装配泡沫铝充填料,同时还设置有缓冲吸能层和吸能盒;本发明通过缓冲吸能层的梯度结构使得在受到冲击时能够实现逐级吸收能量,有助于最大化能量吸收效率,降低对乘员的冲击;吸能盒侧壁开设的诱导槽用于引导变形模式,有效降低了碰撞力峰值;内外管之间采用高强度粘合剂进行连接,确保在受到冲击时连接的稳定性,避免连接处的脱离或损坏,提高保险杠的整体可靠性。
