Forging is one of the common metal material processing methods. It is obtained by pressing the metal blank into the desired shape at room temperature or high temperature. Forgings can be divided into a variety of types, the following details several common classification methods.
Classification by material
Forgings can be classified according to their purpose and the characteristics of the materials needed to make them. The five most common materials are steel, aluminum, magnesium, titanium and nickel-based alloys. These materials are suitable for their respective fields because of their different properties, such as manufacturing cars and aircraft.
Classified according to the mode of production
Forgings can be divided into the following three types according to their production methods: hand forging, mechanical forging and hydraulic forging. Manual forging requires a lot of manpower and material resources, low production efficiency, but personalized customization is more convenient; Mechanical forging using mechanical equipment to complete, higher production efficiency, often used in mass production; Hydraulic forging is through the application of hydraulic keying technology, more pressure is applied during forging, and the forging density is higher and the strength is greater.
Classification according to forging shape
Forgings can also be classified according to their shape. Generally, forgings are divided into shaft, disc, ring and shaped parts. The shaft type refers to the forgings with fixed diameter and varying length. The disk class is a forgings with a flat side as the base of the forgings, which is made into a circular or hexagonal shape. The ring class refers to one or more forged rings with the outer circumference perpendicular to the inner circumference. Finally, the shaped parts are designed and manufactured according to the required geometry.
To sum up, forgings have a wealth of classification methods, by understanding these methods, you can better understand and choose the type of forgings suitable for specific needs and materials.
