Excavator bucket bushing.
Mechanical support and force transmission
Precise positioning and connection:
The I-frame and bucket/arm are fixed by pins to ensure effective force transmission during excavation and avoid structural deformation or dislocation.
It bears the weight of the bucket, material load and excavation impact force, and supports high-frequency reciprocating motion (such as lifting, lowering, and rotation).

Steel material characteristics:
High strength and hardness: Alloy steel (such as 40Cr, 42CrMo) is used and quenched + tempered, the surface hardness can reach HRC45-55, and the wear resistance is significantly better than ordinary carbon steel.
Anti-fatigue design: Optimize the grain structure (such as spheroidizing annealing) to reduce the risk of cracks caused by stress concentration.

Anti-fatigue design: Optimize the grain structure (such as spheroidizing annealing) to reduce the risk of cracks caused by stress concentration.
Raw material preparation
Steel selection: According to the performance requirements of the product, select suitable steel, such as 40Cr, 42CrMo and other alloy steels to ensure that their chemical composition and mechanical properties meet the standards.
Rough machining: The forged billet is clamped on lathes, milling machines, drilling machines and other machining equipment for rough machining. Rough machining can remove most of the excess and leave a machining allowance of 0.5mm-1mm for subsequent fine machining.
Fine machining: After the rough machining is completed, semi-finishing and fine machining are carried out. High-precision grinders, boring machines and other equipment are used to process the inner hole, outer diameter, end face and other key parts of the steel bushing to ensure that the dimensional accuracy and surface roughness meet the design requirements.
Special machining: According to the specific requirements of the product, some special machining procedures may be required, such as machining oil grooves and oil holes on the steel bushing. Special machining methods such as EDM and laser machining can be used.
Heat treatment
Quenching: Heat the machined steel bushing to above the critical temperature, keep it warm for a certain period of time and then cool it quickly to transform the steel structure, obtain high-strength and high-hardness structures such as martensite, and improve the strength, hardness and wear resistance of the steel bushing.
Tempering: After quenching, there is a large internal stress inside the steel bushing, and the toughness is poor, so tempering treatment is required. Tempering is to heat the steel bushing to a temperature range below the critical temperature, keep it warm for a period of time and then slowly cool it to eliminate internal stress, stabilize the structure, improve toughness, and improve comprehensive performance.
Surface treatment
Cleaning and degreasing: Before surface treatment, the steel bushing needs to be cleaned to remove impurities such as oil, iron filings, dust, etc. on the surface to ensure the quality of surface treatment.
Phosphating: A uniform and dense phosphate film can be formed on the surface of the steel bushing, which can improve the corrosion resistance and wear resistance of the steel bushing, and also improve its lubrication performance.
Quality inspection
Dimensional accuracy inspection: Use measuring tools such as calipers, micrometers, and internal diameter gauges to measure the inner diameter, outer diameter, length, wall thickness and other key dimensions of the steel bushing to ensure that the dimensional deviation is within the tolerance range required by the design.
Surface quality inspection: Use methods such as naked eye observation, magnifying glass inspection, and roughness meter measurement to inspect the surface quality of the steel bushing to check whether there are cracks, sand holes, pores, scratches and other defects on the surface, and measure whether the surface roughness meets the standard.
Hardness inspection: Use a hardness tester to test the hardness of different parts of the steel bushing to check whether the hardness meets the requirements after heat treatment to ensure the strength and wear resistance of the steel bushing.
Flaw detection: Use flaw detection equipment (such as ultrasonic flaw detectors, magnetic particle flaw detectors, etc.) to perform flaw detection on the steel bushing to check whether there are cracks, inclusions and other defects inside to ensure the quality and safety of the product.
