Cold Forging Process
Cold forging process overview
Cold forging is to apply pressure to metal at room temperature to make it plastically deform and achieve the desired shape. Cold forging does not require heating of the metal blank, which can make the forgings have higher dimensional accuracy and surface quality. Cold forging is used in the manufacture of precision parts such as automotive parts, electronic accessories, and machinery.
1. Cold forging material selection
It is necessary to select metal materials with good plasticity and formability, such as medium carbon steel, alloy steel, stainless steel, aluminum alloy, copper alloy, etc., with good ductility and low yield strength to ensure that no cracks are generated during the cold forging process.
2. Billet preparation
The selected metal materials are made into suitable billets (such as small pieces, cylinders or bars), and impurities such as surface oxide layer and oil stains are removed.
3. Die design
Design a suitable high-strength steel die according to the shape, size and material properties of the forging.
4. Cold forging press forming
The billet is pressurized by cold forging machinery (such as hydraulic presses, mechanical presses, rolling presses, etc.), and the pressure usually reaches tens to hundreds of tons, causing the blank to undergo plastic deformation.
The billet is gradually pressed into the die under pressure to complete the forming of the part.
5. Forging cooling
After the part is formed, it needs to be naturally cooled to room temperature. The uniformity and stability of the forging can be guaranteed by controlling the cooling rate.
6. Heat treatment
Cold forgings need to undergo heat treatment processes such as annealing, normalizing, quenching and tempering to improve the mechanical properties of forgings such as strength and wear resistance.
7. Subsequent processing and surface treatment
Finishing: Cold forging can provide higher dimensional accuracy, but some parts still need to go through finishing processes such as turning, milling, drilling, etc. to ensure that the final parts meet the accuracy requirements.
Surface treatment: Sandblasting, polishing, painting or electroplating are performed to improve surface finish, corrosion resistance and wear resistance.
