aluminum forging process metal methods of forging warm/hot/cold forging process Advanced Aluminum Forging Technology
Forging is a common metal hot working process, which can process metal materials into parts or blanks with certain shapes, sizes and properties.
The principle of forging is to use a forging machine to apply pressure to the metal blank to make it plastically deformed to obtain the required forgings.
There are two main methods of forging: free forging and die forging.
Free forging refers to the use of impact force or pressure to directly deform the blank between the upper and lower whetstones. It has a simple shape and flexible operation, and is suitable for single-piece or small-batch production.
Die forging refers to the use of pressure in a forging die with a certain shape to fill the die cavity with the blank. It has a complex shape and standardized operation, and is suitable for mass production.
According to the deformation temperature, forging is divided into hot forging, warm forging and cold forging.
Hot forging refers to forging at a temperature higher than the recrystallization temperature of the metal.
Warm forging refers to forging at a temperature lower than the recrystallization temperature.
Cold forging refers to forging at room temperature.
Forging is the plastic deformation of metal in the solid state, which can improve the metal's organizational structure, refine the grains, eliminate cast defects, and improve the metal's strength and toughness. The internal organization of forged parts is relatively uniform, dense, without defects such as pores and inclusions, with a smooth surface, precise dimensions, excellent mechanical properties, wear resistance, corrosion resistance, and impact resistance. It is suitable for important parts that withstand high loads, high temperatures, high speeds and other harsh working conditions.
Forging also has some disadvantages, such as high processing costs, high energy consumption, large equipment footprint, high noise, high technical requirements for operators, high quality requirements for raw materials, and is not suitable for the production of parts with complex shapes and multiple cavities.
Forging is mainly used in aviation, aerospace, automobiles, machinery, metallurgy, petroleum, chemical industry, electric power, rail transportation and other fields. Common forging parts include crankshafts, hubs, gears, shafts, hammers, tools, valves, turbines, engine parts, etc.
