Heavy truck front axle bending die

Abstract

The invention discloses a heavy truck front axle bending die, comprising a lower die and an upper die which are corresponding, wherein the upper surface of the lower die is an upward convex joint face, the lower surface of the upper die is a corresponding upward concave joint face, the middle parts of the lower die and the upper die are provided with matched locating slots corresponding to embossments on the upper and lower sides of I the flanged beam part of a workpiece, and the lower die is provided with a spring plate slot at the position corresponding to the spring plate of the workpiece.The die is characterized in that the periphery of the spring plate slot of the lower die is fixedly provided with a resistance wall, the upper die is provided with a downward boss at the position corresponding to the spring plate of the workpiece, and the boss is exactly arranged in the resistance wall after the upper die and the lower die are assembled and extrudes the spring plate part of the workpiece. By applying the die disclosed by the invention, the purposes of improving the forge piece forming accuracy and improving the material utilization factor can be achieved.

Description

technical field [0001] The invention relates to a forming die for the front axle of a heavy truck, in particular to a die used in the bending step in the forming process. Background technique [0002] The front axle of heavy-duty trucks, especially the front axle components used in Hummer commercial vehicles and military vehicles, generally has a long and symmetrical structure as a whole, with an I-beam section in the middle, and spring plates at both ends of the I-beam section. The two ends of the spring plate part are bent parts, and the two ends of the bent part are wheel connecting parts, wherein the structure of the spring plate part includes a middle protrusion and two spring plates located on both sides of the protrusion. The front axle of heavy-duty trucks with this structure generally adopts processes including roll forging, press bending, final forging and other steps when processing and forming. Among them, roll forging is mainly used for the preliminary forming...
