The quality control and testing means of copper forgings of construction machinery usually include the following aspects:
- Raw material quality control: For copper forgings, the quality of raw materials is one of the key factors affecting the quality of the final product. Therefore, it is necessary to strictly control the quality of raw materials in the production process, including the detection of the chemical composition, mechanical properties and non-metallic inclusions of raw materials.
- Forging process control: In the production process of copper forgings, the control of forging process is crucial to the quality of the product. By controlling forging temperature, pressure, speed and other parameters, the dimensional accuracy, microstructure uniformity and mechanical properties of the product can be guaranteed.
- Heat treatment control: Heat treatment is one of the important processes to improve the performance of copper forging materials. The hardness, strength and toughness of copper forgings can be improved by selecting heat treatment process and controlling heat treatment parameters reasonably.
- Detection means: The commonly used detection means of copper forgings include visual inspection, appearance inspection, size detection, chemical composition analysis, metallographic microscope observation, hardness test, tensile test, etc. These testing methods can evaluate the surface quality, dimensional accuracy, structure and mechanical properties of copper forgings and other important indicators to ensure that product quality meets the requirements.
In addition, in order to improve the quality control level, some advanced non-destructive testing methods, such as ultrasonic testing, magnetic particle testing, eddy current testing, etc., can also be applied to the quality testing of copper forgings. These methods can detect the internal defects of copper forgings and repair or eliminate them according to the test results, thereby improving the reliability and safety of products.
