The invention provides a front anti-collision beam, which belongs to the technical field of vehicles and comprises a front anti-collision beam body, an energy absorption box and a mounting plate. Energy absorption boxes are arranged on the two sides of the front anti-collision beam body, and mounting plates are arranged on the energy absorption boxes; the front anti-collision beam body is of an arc-shaped structure, and the section of the front anti-collision beam body comprises at least two cavity structures. The invention further provides a forming process of the front anti-collision beam. According to the front anti-collision beam, the deformation resistance of the front anti-collision beam body is improved, and the rigidity of the front anti-collision beam body is improved. The equipment and the technological process are simplified, a die system of systems such as a roller bottom type or box type protective atmosphere heating furnace and a special punching machine in the traditional hot punching process and a special die system with a quenching and rapid cooling function are replaced, the production process is simple, the production difficulty is low, and the technological cost is low.
本发明提供了一种前防撞梁,属于车辆技术领域,包括前防撞梁本体、吸能盒和安装板。前防撞梁本体两侧设有吸能盒,吸能盒上设有安装板;前防撞梁本体为弧形结构,前防撞梁本体的截面包括至少两个腔体结构。本发明还提供了一种该前防撞梁的成型工艺。本发明提供的一种前防撞梁,增加前防撞梁本体的抗变形能力,提高前防撞梁本体的刚度。简化了设备及工艺流程,取代传统热冲压工艺中的辊底式或箱式保护气氛加热炉和专用冲压机等系统的模具体系及淬火快冷功能的专用模具体系,生产流程简单,生产难度低,工艺成本较低。
