Excavator bucket bushing.
Connection and support: It is a key component that connects the boom of the excavator with other parts, such as the boom cylinder, fuselage, etc. It can ensure that the relative positions of the various parts are maintained correctly, so that the boom can move according to the design requirements during operation, provide stable support for the movement of the boom, and ensure that the excavation operation can be carried out accurately and efficiently. For example, when excavating materials, the boom bushing allows the boom to work with parts such as the bucket to achieve accurate excavation and loading and unloading of materials.
Reduce wear: During the operation of the excavator, the boom will continuously perform movements such as extension and retraction, swinging, etc., and relative movement and friction will occur between the boom and the connecting parts. The bushing can convert the direct friction between the boom and other parts into friction between the bushing and the parts. Since the bushing is usually made of wear-resistant materials, it can effectively reduce the wear of the boom and other parts, extend the service life of these parts, and reduce maintenance costs and equipment downtime.
Buffering and shock absorption: Excavation operations will generate vibrations and shocks. The boom bushing can play a role in buffering and shock absorption, absorbing and reducing the transmission of these vibrations and shocks to other parts. This helps protect the excavator's structural components and avoids problems such as loose components and fatigue damage caused by long-term vibration and impact. It also improves the operator's work comfort and reduces the impact of equipment vibration on the operator's body.

Metal material
45 steel: It is a medium carbon steel with certain strength and hardness. After appropriate heat treatment, such as quenching and tempering, its comprehensive mechanical properties can be improved. It can meet the use requirements of excavator boom bushings under general working conditions. It has good wear resistance and fatigue resistance, relatively low cost, and is widely used.
40Cr: It is an alloy structural steel with higher strength, toughness and wear resistance than 45 steel. After heat treatment processes such as quenching and tempering, it can improve its surface hardness and wear resistance on the basis of ensuring a certain toughness. It is suitable for excavator boom bushings with high requirements for wear resistance and strength, and can withstand greater loads and more complex working environments.
42CrMo: It is also a commonly used alloy structural steel with high strength, high toughness and good hardenability. Its comprehensive mechanical properties are better than 40Cr, and it can withstand greater impact and torque. It is used in boom bushings of heavy machinery and equipment such as excavators, which can effectively improve the service life and reliability of the bushing, especially for occasions with high working intensity and harsh working conditions.
GCr15: It is a rolling bearing steel with high hardness, wear resistance and contact fatigue strength. It has uniform structure and good dimensional stability. When used in the bushing of excavator boom, it can provide good wear resistance and fatigue resistance, ensuring that the bushing maintains a good working condition under long-term reciprocating motion and load. It is often used for bushings with high requirements for precision and wear resistance.

Raw material preparation
Purchase: According to the product design requirements, purchase suitable steel, copper or other alloy materials as raw materials for the production of bushings to ensure that the quality and performance of the materials meet the standards.
Inspection: Strict inspection of the purchased raw materials, including chemical composition analysis, mechanical properties test, appearance inspection, etc., to ensure that the quality of the raw materials is qualified.
Cutting and blanking: According to the size and shape requirements of the bushing, use cutting equipment to cut the raw materials into suitable blanks. Common cutting methods include flame cutting, plasma cutting, sawing, etc.
Rough machining: Rough machining of the forged or cast bushing blank, including turning the outer circle, inner hole, end face, etc., remove most of the excess, and leave appropriate machining allowance for subsequent finishing.
Finishing: Use high-precision processing equipment and processes, such as CNC lathes, grinders, etc., to finish the bushing to ensure that the size accuracy, shape accuracy and surface roughness of the bushing meet the design requirements.
Drilling, tapping, etc.: According to the design requirements of the bushing, drilling, tapping and other processing operations are performed to meet the assembly and use requirements of the bushing.
Heat treatment
Quenching: Heat the processed bushing to a certain temperature and then cool it quickly to improve the hardness and strength of the bushing.
Tempering: The quenched bushing needs to be tempered to eliminate the quenching internal stress, stabilize the organization and size, improve the toughness of the bushing, and improve its comprehensive mechanical properties.
Surface treatment: According to the needs, the bushing is surface treated, such as nitriding, hard chrome plating, etc., to improve the hardness, wear resistance and corrosion resistance of the bushing surface.
Quality inspection
Dimensional accuracy inspection: Use measuring tools such as calipers, micrometers, three-coordinate measuring machines, etc. to inspect the various dimensions of the bushing to ensure that the dimensional deviation is within the tolerance range required by the design.
Geometric tolerance inspection: Detect the geometric tolerances such as roundness, cylindricity, coaxiality, and verticality of the bushing to ensure that the shape and position accuracy of the bushing meet the requirements.
Surface quality inspection: Detect the surface roughness and surface defects of the bushing through visual inspection, optical microscope, roughness measuring instrument, etc. to ensure good surface quality.
Hardness test: Use a hardness tester to test the hardness of different parts of the bushing to check whether the hardness meets the requirements after heat treatment.
Nondestructive testing: Use nondestructive testing methods such as ultrasonic testing and magnetic particle testing to detect whether there are defects such as cracks and pores inside the bushing.
