The invention discloses a manufacturing process of an automobile energy-absorbing anti-collision beam, and relates to the technical field of automobile anti-collision beam processing, and the manufacturing process comprises the following steps: S1, aluminum ingot raw material casting processing; s2, the plate is subjected to fixed-length slitting machining and hardening; s3, processing the aluminum straight plate; s4, special-shaped aluminum plate machining; s5, bonding and processing the profile; and S6, surface treatment of the anti-collision beam. A single aluminum straight plate and two special-shaped aluminum plates are taken as a group, the two special-shaped aluminum plates are bonded to the two faces of the aluminum straight plate through glue, a plurality of groups of bonded profiles are laminated, bonded and fixed, and a honeycomb cavity structure is formed in the profile, so that when a collision accident of a vehicle occurs, the buffering structure performance of a honeycomb single body plays a role, and the service life of the honeycomb single body is prolonged. The vertical face structure of the honeycomb absorbs impact force from the front face, the honeycomb structure deforms along with the vertical face structure, energy is converted and absorbed, external collision borne by the vehicle is attenuated hierarchically, and collision damage to the vehicle and people in the vehicle can be reduced to a larger extent.
本发明公开了一种汽车吸能防撞梁的制作工艺,涉及汽车防撞梁加工技术领域,包括以下步骤:S1、铝锭原料熔铸加工;S2、板料定尺分切加工及硬化;S3、铝直板加工;S4、异型铝板加工;S5、型材粘合加工;S6、防撞梁表面处理。本发明通过取单片铝直板和两片异型铝板为一组,使用胶水将两片异型铝板粘合在铝直板两面,将多组粘合加工后的型材进行叠层粘合固定,其内部形成蜂窝型空腔结构,使得车辆发生碰撞事故时,蜂窝单体的缓冲结构性能便发挥作用,蜂窝的立面结构将来自正面的撞击力加以吸收,蜂窝结构随之变形,能量进行了转换吸收,将车辆受到的外部碰撞做到了层级衰减,可以更大程度减少车辆及车上人员的碰撞损伤。
