The invention relates to a machining method of a variable cross-section frame longitudinal beam, the variable cross-section frame longitudinal beam and a vehicle, relates to the technical field of automobile machining, can finish machining of the variable cross-section frame longitudinal beam by using a universal bending machine or a roller press, and can manufacture the variable cross-section frame longitudinal beam without a special large hydraulic machine and a longitudinal beam mold. A left longitudinal beam mold and the right longitudinal beam mold do not need to be replaced respectivelyduring stamping forming of the frame longitudinal beam, the process is simpler, the production efficiency is effectively improved, and the production cost can be effectively reduced; longitudinal beamhole sites are machined through numerical control punching equipment, a variable cross-section longitudinal beam body and a variable cross-section longitudinal beam airfoil with different lengths andinflection points are prepared through plasma modification equipment, and the modified longitudinal beam body and the modified longitudinal beam airfoil are riveted to form the frame longitudinal beam. Variable cross-section longitudinal beams with different lengths and different inflection points do not need to be manufactured through a plurality of molds with different specifications, and therefore the production efficiency can be effectively improved, and the production cost can be effectively reduced.
本申请涉及一种变截面车架纵梁的加工方法、变截面车架纵梁及车辆,涉及汽车加工技术领域,使用通用的折弯机或辊压机即可完成变截面车架纵梁的加工,无需专用的大型液压机和纵梁模具就可以进行变截面纵梁的制造,且在车架纵梁冲压成型时无需分别更换左右纵梁模具,工序更为简单,有效提高了生产效率和可有效降低了生产成本;通过数控冲孔设备完成纵梁孔位的加工,通过等离子修形设备制备具有不同长度和拐点的变截面纵梁主体和变截面纵梁翼面,且将修形后的纵梁主体和纵梁翼面进行铆接形成车架纵梁,不需要通过多个不同规格的模具来制造不同长度和具有不同拐点的变截面纵梁,因此,本申请可以有效提高生产效率和降低生产成本。
