The failure analysis and prevention strategy of copper forgings of construction machinery is an important link to ensure its normal operation and extend its service life. The following are detailed answers to these two aspects:
Failure analysis:
- Fracture failure: Copper forgings may fracture due to insufficient material strength or excessive force. Strength calculation and stress analysis can be used to assess whether the strength of the material meets the design requirements, and whether the stress situation is within the safe range in actual use.
- Fatigue failure: During the use of construction machinery, copper forgings may experience cyclic stress due to factors such as vibration, impact load and repeated loading, resulting in fatigue failure. Fatigue performance of copper forgings can be evaluated through fatigue test and calculation, and corresponding measures can be taken to increase the fatigue life of copper forgings, such as increasing the strength of materials, improving the surface quality, optimizing the structure design, etc.
- Corrosion failure: Copper forgings may suffer corrosion failure in humid, acidic or alkaline environments. The effect of corrosion can be reduced and the corrosion failure of copper forgings can be delayed by material selection, protective coating and anti-corrosion treatment.
Prevention strategies:
- Material selection: Select copper alloy with high strength and good corrosion resistance as the material of copper forgings to improve its mechanical properties and durability.
- Design optimization: In the design process of copper forgings, the stress situation, stress concentration area and the design to avoid stress concentration are taken into account to reduce the stress level and reduce the risk of fracture and fatigue failure.
- Manufacturing quality control: Ensure that the manufacturing process of copper forgings is carried out in strict accordance with the specifications, including material selection, heat treatment and forging process, etc., to ensure that the quality and performance of copper forgings meet the design requirements.
- Surface treatment and protection: The use of appropriate surface treatment methods, such as coating, spraying or heat treatment, improve surface hardness and corrosion resistance, reduce the risk of corrosion failure.
- Regular inspection and maintenance: Regular inspection and maintenance of copper forgings of construction machinery, timely discovery of existing problems, and repair or replacement to prevent further failure and damage.
