Casting Method Of Copper Bushing
Metal-type copper bushing casting refers to a casting method where liquid metal is poured into a metal mold, known as the metal type, under the influence of gravity. The metal then cools and solidifies in the mold to obtain the castings. This process benefits from the high thermal conductivity and heat storage capacity of the metal mold, resulting in fast cooling of the liquid metal and producing castings with dense microstructures and high mechanical properties. Additionally, metal-type casting offers high dimensional accuracy and low surface roughness values.
Sand casting is a casting method that produces castings using sand molds. Steel, iron, copper bushings, and most non-ferrous alloy castings can be obtained using the sand casting method. Sand casting is favored for its low-cost molding materials and easy availability, as well as its adaptability to single-piece production, batch production, and large-scale production.
Centrifugal casting involves pouring liquid metal into a rotating mold, where under the action of centrifugal force, the metal fills the mold and solidifies to form the copper bushing. The distinctive feature of centrifugal casting is that the metal liquid is forced into the mold and solidifies due to centrifugal force, resulting in good metal feeding and solidification, dense outer microstructure, reduced non-metallic inclusions, and excellent mechanical properties. This method eliminates the need for mold and core making, saving on related materials and equipment investments.

The role of copper sleeves in construction machinery
The copper bushing plays a vital role in various engineering machinery devices such as excavators, loaders, bulldozers, cranes, boom-style concrete pumps, and aerial work vehicles. It is a commonly used joint component in the articulated structures of these machines. A properly designed copper bushing should have a reasonable clearance, which allows the storage of lubricating grease. This ensures that the bucket shaft and bushing experience reduced wear and resistance during relative movement. The appropriate clearance also allows for a certain amount of space to accommodate the thermal expansion that occurs when the shaft and bushing move relative to each other, preventing sintering.
If the clearance in the joint exceeds specifications, it can lead to a loose fit between the shaft and bushing, causing vibration, impact, and uneven wear. This can accelerate wear and even result in the fracture of the bucket shaft, posing significant equipment and safety risks. Excessive joint clearance can also cause deviations and instability in the operation of the engineering machinery, leading to decreased operational precision and efficiency. Therefore, maintaining a proper joint clearance is crucial for improving the reliability of engineering machinery.
Copper bushings are mechanical lubrication components available in various types based on their materials and manufacturing processes. In the case of engineering machinery, graphite copper bushings are commonly used.
Graphite copper bushings are made using graphite as a material, which has a relatively loose structure, making it easy to create holes and cavities during production. The surface of the bushing is embedded with solid lubricants, creating a self-lubricating bearing. This reduces the need for lubricating oil while enhancing the efficiency of the engineering machinery.
As the number and sophistication of engineering machinery continue to grow, the demand for components like copper bushings and bearings is rapidly increasing. Copper bushings, being critical elements that enable the machinery to function, are essential to select wisely.
Graphite copper bushings, with their self-lubricating properties, enable engineering machinery to operate smoothly, reducing the consumption of various materials and enhancing overall efficiency. Therefore, for large, heavy-duty, and complex machinery, including engineering machinery, graphite copper bushings and self-lubricating bearings are preferred choices to ensure optimal performance.
