Embodiment Construction

[0037] Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0038] figure 1 It is a structural schematic diagram of the automobile axle housing body in the embodiment of the present invention. Such as figure 1 As shown, the automobile axle housing 10 of this embodiment is composed of a main body, and the main body is composed of a hollow portion 11 and a raised portion 12 . The hollow part 11 extends along its length direction to form two ends, and is symmetrical about the center line formed by the two ends, and the part between the two ends has a first part connecting the two ends and parallel to each other. side and second side.

[0039] A through hole is provided in the middle of the first side, which is used when the axle housing accommodates the rear axle differential and speed reducer of the automobile. The protruding portion 12 is located on the second side surface corresponding to the through...

Abstract

The invention discloses an automobile axle housing, an automobile axle housing forming die and an automobile axle housing forming method. The automobile axle housing forming method includes subjecting a round steel pipe to secondary internal high pressure to form a middle portion, performing forward extruding diameter shortening on two ends, performing compression forming on the middle portion, and cutting and processing an upper-side middle through hole. The automobile axle housing of a novel structure is formed by the method and the die. The automobile axle housing has a body of a hollow structure, the body extends along the length direction of the same to form two end portions, is symmetrical according to a central line formed by the two end portions, and gradually shrinks from the middle to the two end portions, a portion positioned between the two end portions has two side faces which are both connected with the two end portions and parallel to each other to serve as a first side face and a second side face, the through hole is formed in the middle of the first side face, a protrusion portion protruding towards a direction away from the body is arranged at a position, corresponding to the through hole, of the second side face, and the two end portions and the portion positioned between the same are integrally formed to be the body which is free of a welding seam.

Description

technical field [0001] The invention relates to a forming method of an automobile part, a forming die and a formed product. In particular, it relates to a forming method of an automobile axle housing body, a forming die and a formed product. Background technique [0002] In the past stamping and forming of automobile axle housings with steel plates, the steel plates were cut and blanked into two pieces of blanks, and the two pieces of blanks were stamped into two pieces of bow-shaped channel parts respectively, and the welding seams were cut and processed, and then the two pieces of bow-shaped grooves were cut. The groove parts are butt-welded to form the main body of the axle housing, and then the rear cover is welded to form the main body of the axle housing. Therefore, an axle housing body needs to be stamped and welded with three steel plates. The axle housing body produced by this method has long welding seams and high welding quality requirements. If the control is n...
