Embodiment 1

[0028] A steering knuckle forming process includes the following steps:

[0029] (1) Cutting

[0030] The raw material inspection is first performed before cutting. The method of the raw material inspection is to detect the composition of the round steel blank of the steering knuckle, save the round steel blank after the inspection is passed, and then polish the round steel blank with sandpaper 2 After polishing, use dilute sulfuric acid to remove impurities on the surface of the round steel billet, then rinse it with distilled water for 1 min, dry it and perform sawing according to the size of the knuckle, the concentration of the dilute sulfuric acid is 30%;

[0031] (2) Heating

[0032] Place the blanked round steel billet in a double-hearth intermediate frequency induction furnace for heating. The double-hearth intermediate frequency induction furnace has a heating rate of 50°C / min, and the temperature of the double-hearth intermediate frequency induction furnace after heating is ...

Embodiment 2

[0044] A steering knuckle forming process includes the following steps:

[0045] (1) Cutting

[0046] The raw material inspection is first performed before cutting. The method of raw material inspection is to detect the composition of the round steel blank of the steering knuckle, store the round steel blank after the inspection is passed, and then sand the round steel blank with sandpaper 3 After polishing, use dilute sulfuric acid to remove impurities on the surface of the round steel billet, then rinse it with distilled water for 2 minutes, dry it and perform sawing according to the size of the knuckle. The concentration of the dilute sulfuric acid is 35%;

[0047] (2) Heating

[0048] The blanked round steel is placed in a double-hearth intermediate frequency induction furnace for heating. The double-hearth intermediate frequency induction furnace has a heating rate of 55°C / min, and the temperature of the double-hearth intermediate frequency induction furnace after heating is 1200...

Embodiment 3

[0060] A steering knuckle forming process includes the following steps:

[0061] (1) Cutting

[0062] The raw material inspection is first performed before cutting. The method of the raw material inspection is to detect the composition of the round steel blank of the steering knuckle, save the round steel blank after the inspection is passed, and then polish the round steel blank with sandpaper 4 After polishing, use dilute sulfuric acid to remove impurities on the surface of the round steel billet, then rinse it with distilled water for 2 minutes, dry it and perform sawing according to the size of the knuckle. The concentration of the dilute sulfuric acid is 40%;

[0063] (2) Heating

[0064] The round steel billet after blanking is placed in a double-hearth intermediate frequency induction furnace for heating. The double-hearth intermediate frequency induction furnace has a heating rate of 60°C / min, and the temperature of the double-hearth intermediate frequency induction furnace af...

Abstract

The invention discloses a steering knuckle forming process. The material utilization rate of the steering knuckle can reach more than 70% after adopting the new forming process, the mechanical properties of the product are improved, the metal streamlines are complete, and the mechanical properties and corrosion resistance of the product are obviously improved. The control of final forging temperature and forming force can simplify the process, and the final forging can be completed on ordinary hot die forging presses, reducing equipment investment. The production process of this brake pad has the advantages of high material utilization rate and small equipment investment. The market prospect broad.

Description

Technical field [0001] The invention relates to the field of steering knuckles, in particular to a steering knuckle forming process. Background technique [0002] The steering knuckle, also known as the "horn", is one of the important parts in the steering axle of the car, which can make the car run stably and transmit the driving direction sensitively. The function of the steering knuckle is to transmit and bear the front load of the car, support and drive the front wheel to rotate around the kingpin to turn the car. In the driving state of the car, it is subjected to variable impact loads, therefore, it is required to have high strength. The current steering knuckle forming process has the problem of unstable forging quality. [0003] CN200910191031.9 discloses a heavy-duty truck steering knuckle forging forming process, which includes a) drawing rod: using a 750kg air hammer to draw a round steel billet to form a workpiece composed of a cylindrical section and a truncated cone...
