Abstract

The invention belongs to the field of forging, and discloses a forging process of a heavy truck front axle. The forging process comprises the following steps of (1) feeding, (2) heating, (3) roll extrusion, press bending, pre-forging, finish forging, side cutting and correction, (4) heat treatment, (5) surface cleaning, (6) shot blasting, (7) flaw detection, (8) straightening, (9) paint spraying and (10) inspection. According to the scheme, the process is simple and is assisted by whole-process precise temperature control, the inner structure uniformity, the performance index and the machiningforming rate of a workpiece are effectively improved, the mechanical performance and the physical performance of the workpiece are improved, then the usability of the front axle is improved, and thefatigue life of the front axle is prolonged; and no burr is prone to being generated to a produced forged part, no waste side is generated, product quality is guaranteed, the reasonable quenching temperature, soaking time and quenching media are adopted in the heat treatment process, the defects that hardness of the front axle is not uniform and the metallographic structure is poor are overcome, hardness uniformity of the front axle is improved, and the service life of the front axle is prolonged.

Description

technical field [0001] The invention relates to the technical field of forging, in particular to a forging process of a heavy truck front axle. Background technique [0002] The front axle is one of the security parts with heavy load on the heavy truck, which requires high strength and fatigue life, especially when the heavy truck brakes suddenly downhill, the front axle will bear more than 2 / 3 of the truck load, so The forging process of the front axle has higher requirements. [0003] At present, the workpieces produced by the forging process of the front axle of heavy trucks still have the defects of uneven surface hardness and unqualified fatigue performance, resulting in shortened service life of the front axle of heavy trucks. Contents of the invention [0004] (1) Solved technical problems [0005] 1. Technical problems to be solved [0006] In view of the problems existing in the prior art, the object of the present invention is to provide a forging process for ...
