Problems solved by technology

At present, the conventional forging process is die forging, which needs to be heated many times. The process is generally: heating - breaking - pre-forging flange - heating - final forging flange - forming - annealing - internal and external machines Machining—heat treatment—finishing can produce the hub shaft tube. This kind of manufacturing process is solid and consumes a lot of materials.
And it is difficult to form a full-fiber metal flow line distributed along the axial direction, the mechanical properties and fatigue life of the parts are low, and it is difficult to meet the special quality requirements of the vehicle

Abstract

This invention relates to a load automobile hub axle tube whole fiber forging and shaping process and its mould. It is characterized by the following: adopting solid material; finishing hub axle tube surface and deep hole extrusion shaping to get the whole fiber metal flow wire along axle direction and the inner hole is shaped by extrusion without process.

Description

Technical field: [0001] The invention belongs to the technical field of general vehicles, and in particular relates to a full-fiber forging forming process and mold for a hub shaft tube of a truck. Background technique: [0002] Automobile hub shaft tubes are mainly used for stamping and welding axle housings and wheel side supports at both ends of drive axles of engineering vehicles. It is an important security component. It is welded to both ends of the axle housing, and the half shaft passes through it. During the driving process of the vehicle, it not only bears the weight of the entire body and the cargo on board, but also bears the complex alternating stress due to the change of road conditions. Streamlined, dense metal structure and extremely high fatigue life. At present, the conventional forging process is die forging, which needs to be heated many times. The process is generally: heating - breaking - pre-forging flange - heating - final forging flange - forming ...
