With the development of construction machinery industry and technological progress, aluminum forgings, as a lightweight, high strength, good corrosion resistance material, are widely used in various construction machinery and equipment. This paper will introduce the manufacturing process of aluminum forgings of construction machinery and its application in the field of construction machinery.
- Manufacturing process
- Raw material preparation: Aluminum alloy is one of the most commonly used materials in casting materials, and the raw material used in manufacturing aluminum forgings is aluminum alloy. Aluminum alloys with good plasticity and malleability are usually selected, such as 6XXX series, 7XXX series, etc.
- Mold manufacturing: The shape and size of aluminum forgings have higher requirements, and corresponding molds need to be manufactured according to product design requirements. Molds are generally made of high-quality tool steel and processed by CNC machine tools.
- Heating treatment: Aluminum forgings need to be heated before forging to improve the plasticity and forging performance of the material. The commonly used heating treatment methods are solution treatment and aging treatment.
- Forging forming: The heated aluminum alloy material is put into the mold for forging, usually using cold forging or hot forging process. Cold forging is suitable for small batch production of aluminum alloy forgings, while hot forging is suitable for large batch production.
- Cooling treatment: Aluminum forgings need to be cooled after forging to improve their mechanical properties and organizational stability. The common cooling treatment methods are water quenching and natural cooling.
- Application field
Aluminum forgings are widely used in various construction machinery and equipment, such as excavators, loaders, bulldozers, cranes and so on. It is mainly used in the following aspects: - Structural parts: Construction machinery aluminum forgings as structural parts, with good strength and rigidity, can withstand greater load and impact. For example, the aluminum forging arm, bucket teeth and track plate of the excavator.
- Moving connectors: Construction machinery aluminum forgings can also be used as moving connectors, such as steering gears, transmission shafts and connecting rods, etc., to ensure the normal operation and stability of construction machinery and equipment.
- Hydraulic components: Aluminum forgings can also be applied to the hydraulic system of construction machinery and equipment, such as hydraulic cylinder, hydraulic valve body and hydraulic pump body, to achieve accurate control and efficient work of hydraulic transmission.
- Auxiliary parts: In the field of construction machinery, aluminum forgings can also be used to manufacture various auxiliary parts, such as radiator shells, fan blades and seat brackets, to improve the overall performance and comfort of construction machinery equipment.
In summary, the manufacturing process of aluminum forgings in construction machinery and its application in the field of construction machinery play an important role. With the continuous progress of science and technology and the increasing demand, aluminum forgings will develop more widely and deeply in the field of construction machinery.
