Problems solved by technology

[0002] The suspension system is an important part of a modern car, which has a great influence on the ride comfort and handling stability of the car. The steering knuckle is one of the main parts on the steering axle of the car, which can make the car run stably and transmit the drive sensitively Direction, the function of the steering knuckle is to bear the front load of the car, support and drive the front wheel to rotate around the kingpin to turn the car; and as the demand for cars increases and the output increases, the processing efficiency of the steering knuckle The requirements are becoming more and more stringent, and the existing processing methods and processes are difficult to meet the output requirements of steering knuckles

Embodiment Construction

[0027] A process for processing an aluminum alloy steering knuckle, characterized in that it comprises the following steps:

[0028] S1: Cutting: use 6082 aluminum alloy as raw material, use extruded aluminum rod sawing machine to saw material according to φ26-125;

[0029] S2: The first heating: the heating temperature is controlled at 980°C-1180°C, and the heat is kept for 0.5 hours;

[0030] S3: Billet making: use industrial manipulators to transfer the raw materials heated by S2 to the forging press for the first forging press, and obtain the steering knuckle blank;

[0031] S4: The second heating: the heating temperature is controlled at 1060°C-1180°C, and the temperature is kept for 2 hours;

[0032] S5: Rough forging: Transfer the blank heated by S4 to the forging press for the second forging with an industrial manipulator;

[0033] S6: The third heating: the heating temperature is controlled at 1080°C-1380°C, and the temperature is kept for 2 hours;

[0034] S7: Fin...

Abstract

The invention relates to an aluminum alloy steering joint machining process. The aluminum alloy steering joint machining process is characterized by comprising the following steps that S1, blanking isconducted, wherein a 6082 aluminum alloy is used as a raw material, and an extrusion aluminum bar sawing machine is adopted for sawing according to phi 26-125; S2, heating is conducted for the firsttime; S3, a blank is prepared; S4, heating conducted for the second time; S5, rough forging is performed; S6, heating is performed for the third time; S7, finish forging is conducted; S8, trimming isconducted, wherein a steering joint blank final forge piece obtained after S7 is transferred into a forging press through an industrial mechanical arm to be forged and pressed, and waste edges of thesteering joint blank final forge piece are cut off; S9, initial inspection is conducted, wherein the final forging piece of the steering joint blank subjected to S8 is inspected according to a drawing; S10, heat treatment is conducted; S11, final inspection is conducted, wherein appearance and size inspection is conducted on the steering joint blank final forge piece subjected to heat treatment inthe step S10; and S12, packaging is conducted, wherein the steering joint blank final forge piece qualified through final inspection in the step S11 is packaged. The method has the beneficial effectsthat the integrally forged and pressed steering joint is good in forming; fatigue cracking is not likely to happen; and the defects of folding, hole shrinkage and the like are avoided.
