Aluminum forgings of construction machinery are widely used and play an important role in modern manufacturing industry. In order to ensure the quality and performance of the parts, it is crucial to choose the right processing technology and equipment. The following will introduce some commonly used construction machinery aluminum forging processing technology and equipment.
- Forging process:
Forging of aluminum forgings is a common processing method, which improves the internal structure and properties of the material by plastic deformation and compaction. The forging of aluminum forgings can be divided into several ways such as free forging, die forging and isostatic forging. Free forging is suitable for simple shape parts, die forging is suitable for complex shape parts, isostatic forging is suitable for high-precision and high-complexity parts. Forging technology can improve the strength and toughness of aluminum forgings and improve the grain structure. - CNC machining:
Numerical control machine tool is the main equipment widely used in aluminum forging processing of construction machinery. CNC machine tools can be pre-programmed to achieve high precision, stability and high efficiency machining. Commonly used CNC machine tools include lathes, milling machines and drilling machines, etc., which can carry out various forms of processing operations, such as turning, milling, drilling, threading, etc. CNC machining can achieve complex shapes and high precision aluminum forgings. - Sandblasting treatment:
Sandblasting is a common surface treatment process, which is suitable for rust removal, cleaning and surface treatment of aluminum forgings in construction machinery. By spraying abrasive onto the surface of the aluminum forgings, surface oxidation layers, dirt and uneven dimensions can be removed and a consistent surface quality can be obtained. Sandblasting can improve the surface finish of aluminum forgings, reduce the surface roughness, and provide better conditions for subsequent painting or other surface treatment. - Heat treatment:
Heat treatment is an important processing technology of aluminum forgings in construction machinery. By heating and cooling the material, the structure and properties of the material can be changed. Common heat treatment methods include solution treatment and aging treatment. Solution treatment is done by heating aluminum forgings to solution temperatures to dissolve the alloying elements in the solid solution, and then rapidly cooling to maintain the solution state. Aging treatment is to keep the solid solution at a certain temperature for a period of time, so that it forms a strengthening phase and improves the strength and hardness of aluminum forgings.
In summary, the processing technology and equipment of construction machinery aluminum forgings involve forging process, CNC processing, sandblasting treatment and heat treatment. In practical applications, appropriate processing methods and equipment should be selected according to the shape, size and requirements of aluminum forgings to ensure that the quality and performance of parts meet the expected goals. At the same time, reasonable process parameters and operational control are also key factors to ensure successful processing.
