The invention provides a preparation process of an automobile stiffening beam and the stiffening beam, and the preparation process comprises the following steps: S100, extruding an aluminum alloy raw material to form an aluminum alloy profile structure with a cavity structure; s200, first supporting blocks are placed from the two ends of the profile structure to the middle connecting part correspondingly; s300, a first supporting block is fixed; s400, a connecting hole and a mounting hole are machined in the profile structure, and the middle connecting hole is a through hole penetrating through the profile structure and the first supporting block; s500, second supporting blocks are placed from the two ends of the profile structure to the end connecting parts correspondingly; and S600, the second supporting block is fixed, and the stiffening beam is obtained. In the preparation process, the first supporting blocks and the second supporting blocks are placed at the middle connecting parts and the end connecting parts correspondingly, and the supporting blocks can support the corresponding connecting holes or mounting holes, so that the strength of the connecting and fixing positions of the stiffening beams is improved; the problems that induced deformation and torque attenuation are prone to occurring at the connecting and fixing positions of the stiffening beams when an automobile collides are solved, and the connecting strength is improved.

    本申请提供了一种汽车加强梁的制备工艺及加强梁,其中,制备工艺包括:S100:对铝合金原材料进行挤压,形成具有型腔结构的铝合金型材结构;S200:自型材结构的两端分别放入第一支撑块至中部连接部位;S300:固定第一支撑块;S400:在型材结构上加工连接孔和安装孔,中部连接孔为贯穿型材结构和第一支撑块的通孔;S500:自型材结构的两端分别放入第二支撑块至端部连接部位;S600:固定第二支撑块,得到加强梁。在制备过程中,在中部连接部以及端部连接部处分别放置了第一支撑块和第二支撑块,支撑块能够对对应的连接孔或安装孔进行支撑,从而提高加强梁连接固定处的强度,避免了汽车在碰撞时加强梁连接固定处易发生诱导变形及力矩衰减的问题,提高了连接强度。
