Benefits of technology

This invention provides an improved method called automated precise forge (APF) that allows for better control over how well-forged parts work on metal products such as disk brake rotors or axially orientable bearings used in machinery. It achieves greater stability compared with previous methods while producing consistently good results at lower costs relative to current processes.

Problems solved by technology

This patented technical problem addressed by this patents relates to improving the accuracy and stability during manufacturing processes used on vehicles' steering system (SRS). Steering Knifles have complicated shapes with many different types of materials that require specialized processing techniques like machining before assembly into finished products. These challenges make them expensive and prone to failure due to poorly filled material inside these structures.

Embodiment

[0013] 1) Material preparation: use a semi-automatic band sawing machine to saw the Φ150 bar material according to the size Φ150X340±1, and the end face slope is less than 2° to meet the requirements of the upsetting forming process.

[0014] 2) Heating: double-hearth medium-frequency induction furnace heating, heating temperature 1200 ℃, heating cycle 45 seconds, automatic monitoring of blank temperature, automatic discharge, automatic sorting of unqualified temperature blanks, to ensure that the blanks are not overheated or overheated, and the internal quality of the blanks is guaranteed Meet the requirements of forging forming.

[0015] 3) Precision forging: the mold is preheated to 220°C, the mold is lubricated with graphite milk, and the precision forging is formed by the four-station automatic production line of the 8000T hot forging press, and the production cycle is 45 seconds.

[0016] Upsetting: the initial forging temperature is 1180°C, put the heated blank on the upse

Abstract

The invention relates to a novel process for precision forging of a disc steering knuckle, which comprises sawing, heating, blanking, forging, trimming, aligning and heat treating, wherein a forging procedure refers to the precision forging carried out by a hot die forging press. The precision forging comprises the following steps of: upsetting and descaling, semi-closed type extruding and preforming of a rod part and a head part, preforging and forming of a head part and a rod part, and finish forging and finishing. The process has the advantages that the process for the precision forging of the disc steering knuckle is advanced, the precision of a product can conform to the precision rank specified in national standard, the quality of a forge piece is stable, and the production efficiency is high.
