>> Product Name

Excavator bucket bushing.


>> Product Use

Connection and support: As a key component of the excavator bucket, it is used to connect the bucket with other parts of the excavator, such as the boom, dipper rod, etc., and plays a stable supporting role, ensuring that the bucket can maintain the correct position and posture during the work process, making the connection between the bucket and other parts more reliable, and ensuring the stability and accuracy of the entire excavation work.

Reduce friction and wear: When the excavator is working, the bucket will frequently perform excavation, loading, unloading and other actions, and a lot of friction and wear will be generated between the parts. The bushing can effectively reduce the friction coefficient between the bucket and the connecting parts, reduce direct contact and wear between the parts, thereby extending the service life of the bucket and related parts, and reducing maintenance costs and equipment failure rates.

Buffering and shock absorption: Various impact forces and vibrations will be generated during excavation operations. The bushing can play a role in buffering and shock absorption, absorb and disperse these forces, reduce the impact on the bucket and other structures of the excavator, protect the structural integrity of the equipment, and improve the working reliability and stability of the equipment. At the same time, it also helps to reduce the vibration felt by the operator and improve the comfort of the working environment.

>> Product Raw Material

Metal material

Carbon steel: It has high strength and hardness, can withstand various forces that the bucket is subjected to during operation, ensure the structural stability of the bushing, and is not easy to deform and damage. At the same time, the cost of carbon steel is relatively low, and it has good economy.

Alloy steel: On the basis of carbon steel, alloy elements such as chromium, molybdenum, and vanadium are added to further improve the strength, toughness and wear resistance of the material. It can better adapt to the complex and harsh working environment of the excavator and extend the service life of the bushing.

Raw material preparation

Material selection: According to the product performance requirements, select suitable metal materials, such as carbon steel, alloy steel, etc.

Cutting: According to the size specifications of the bushing, use cutting equipment to cut the raw materials into suitable blanks. Common cutting methods include sawing, laser cutting, flame cutting, etc.

Forming processing

Turning: Clamp the blank on the lathe, and use the turning tool to rotate and cut the blank to process the basic shapes of the inner and outer cylindrical surfaces, end faces, etc. of the bushing to ensure dimensional accuracy and surface roughness.

Drilling: According to the design requirements of the bushing, use a drilling machine to drill various mounting holes, oil holes, etc. on the bushing.

Grinding: Grind the bushing after turning to further improve the dimensional accuracy and surface finish of the bushing, reduce the surface roughness, and improve the matching accuracy of the bushing with other components.

Surface treatment

Quenching: Quench the bushing made of metal material, heat the bushing to a certain temperature and then cool it quickly to improve the hardness, strength and wear resistance of the bushing.

Tempering: There is a large internal stress inside the bushing after quenching. Tempering treatment can eliminate the internal stress, stabilize the structure and size, and improve the toughness of the bushing.

Phosphating treatment: A layer of phosphate chemical conversion film is formed on the surface of the bushing through chemical and electrochemical reactions, which plays a role in rust prevention, lubrication and improving coating adhesion.
