Embodiment 1

[0017] (2) A truck axle housing

[0018] The axle housing is a part of a truck

[0019] The main parameters of the axle housing:

[0020] wxya

135mmX150mm

D

508mm

D1

135mm

[0021] Among them, B: the thickness of the axle housing, B1: the width of the square mouth of the axle housing, D: the maximum diameter of the axle package in the middle of the axle housing, D1: the diameter of the end of the axle housing

[0022] The axle housing adopts the shrinking-local pressing-extrusion bulging process as follows: first select the tube blank with a diameter of φ170mm, that is, seamless steel tube, then reduce the diameter of both ends of the tube blank, and directly shrink two The required size of the end is 135mm; the middle of the tube blank including the leaf spring seat area is pressed to 135mmX150mm; the middle of the tube blank is extruded and bulged and the parts are shaped to reach the drawing size, the bevel is made and the tri...

Abstract

The invention relates to a manufacturing method for automotive axle housing, which belongs to the manufacturing method for a steel automotive axle housing. The method comprises the following steps specifically: firstly utilizing a round steel tube to carry through diameter reducing at two ends and then utilizing a forcing press to carry through shape pressing on partial areas in the middle of a roughcast; opening a long slot passing from front to back in the middle of a tube roughcast; then carrying out extrusion in the middle of the tube roughcast to expand the middle of the tube roughcast to be jointed with the shape of a die; finally carrying out shaping on the axle housing to reach the roughcast dimension of an axle housing part. The roughcast is processed partially and welded with a set square to form a complete axle housing part. The method has the advantages of few working procedures, low cost, small attenuation degree in the middle area of the axle housing, high axle housing intensity, few disposable investments on device, high manufacturing efficiency, being suitable for batch manufacturing, simple technique of axle housing manufacturing, low reform cost and the die can realize standardization.

Description

Technical field: [0001] The invention relates to a method for manufacturing an automobile axle housing, which belongs to the field of automobile axle housing processing. Background technique: [0002] At present, there are mainly four kinds of processes in the production of automobile axle housings. One is casting process, and the other is punching and welding process. , also need to weld the triangular plate), the third is to adopt the garden pipe, the process plan of slotting, splitting, expanding, shaping, reducing the diameter, and repairing the triangular plate. The fourth is the use of square tubes, slotting in the middle, splitting, and expansion processes. With the development of the automobile industry, steel axle housings emerge as the times require, and stamped and welded axle housings are widely used in the production of axle housings. The produced axle housing has low cost and high efficiency. At present, it is widely used in light vehicles, medium vehicles a...
