The invention provides an integrated warm-formed dash panel cross beam, a forming method and an application vehicle thereof, the integrated warm-formed dash panel cross beam comprises a dash panel body part, and the dash panel body part comprises a dash panel upper cross beam, a left side panel assembly part and a right side panel assembly part. The dash panel cross beam structure has the beneficial effects that the dash panel cross beam structure is high in space utilization rate and low in weight, the cabin arrangement requirement can be met, and more space is saved; meanwhile, the whole cabin upper frame can be completely supported through the structural design, and the collision performance and rigidity of the cabin are greatly improved; moreover, the U-shaped semi-closed cavity from the left cross beam connector to the right cross beam connector is defined by the cross beam shell, the structure is simple and easy to form, the cross section size of the cross beam body is small, and compared with a box-type structure, a large number of materials are saved, so that the overall light weight level of the vehicle is greatly improved, and the service life of the vehicle is prolonged. The collision performance, the bending rigidity and other performance are met, and meanwhile the cost is reduced.

    本发明提供了一体化温成型的前围板横梁、成型方法及其应用车辆,包括前围横梁本体零件,所述前围横梁本体零件包括前围板上横梁、左侧围板总成部件和右侧围板总成部件。本发明有益效果:本发明的前围板横梁结构空间利用率高,重量低,可以满足坐舱布置需求,节省较多空间;同时,本发明结构设计可以完整支撑整个坐舱上部框架,大大提升了坐舱的碰撞性能和刚度;并且,本发明横梁壳体围成自横梁左接头向横梁右接头的U形半封闭腔体,结构简单易于成形,且横梁本体的截面尺寸小,相比于箱式结构,节省了大量材料,使得车辆的整体轻量化水平得到较大提升,满足了碰撞性能、弯扭刚度等性能的同时降低了成本。
