The invention discloses a high-strength steel punch forming reel pipe torsion beam, and the torsion beam comprises a torsion beam body; the torsion beam body comprises a reel pipe and three middle strips; the middle strips are integrally arranged on the inner side wall of the reel pipe, end blocks are welded to the two ends of the torsion beam body, and the cross section of each end block is in a right triangle shape. A longitudinal arm and a connecting plate are welded to the two ends of the torsion beam. According to the high-strength steel punch forming reel pipe torsion beam, the mode that the middle strip is integrally arranged on the inner side wall of the hollow reel pipe is adopted, the structural strength is improved, breakage is not prone to occurring, and the weight of the whole torsion beam is reduced; the end blocks with the right-triangle-shaped cross sections are welded to the two ends of the torsion beam, the structural strength of the two ends of the torsion beam is improved, the area of the connecting positions of the two ends of the torsion beam and an automobile is increased, the connecting positions are prevented from being broken, the whole torsion beam is in a curve shape with the two thickened ends, and the structural strength is high.
本发明公开了一种高强度钢冲压成型卷管扭力梁,包括扭力梁,所述扭力梁包括卷管和中间条,所述卷管内侧壁一体化设置有中间条,所述中间条有三条,所述扭力梁两端均焊接有端块,所述端块横截面呈直角三角形状,所述扭力梁两端焊接有纵臂和连接板,本发明高强度钢冲压成型卷管扭力梁采用空心卷管内侧壁一体化设置有中间条的方式,即增加了结构强度,不易断裂,又减轻了整个扭力梁的重量,扭力梁两端均焊接有横截面呈直角三角形状的端块,增加扭力梁两端的结构强度,使扭力梁两端与汽车的连接处面积增大,防止连接处断裂,整个扭力梁形状呈两端加粗的曲线形,结构强度高。
