Surface quality control and upgrading methods of copper forgings for agricultural machinery

As an important part of agricultural machinery, the surface quality of copper forgings is directly related to the performance and service life of agricultural machinery and equipment. In order to improve the surface quality of agricultural copper forgings, we can control and improve from the following aspects.

First of all, material selection is the basis for ensuring the surface quality of copper forgings. We should choose high-quality copper materials as raw materials to ensure its purity and intrinsic quality. When choosing copper materials, the primary consideration is the lead content of the material, because the lead content directly affects the plasticity and surface quality of copper forgings. We should choose copper materials with low lead content to ensure that copper forgings are not prone to defects and pores during the forging process.

Secondly, strict control of forging process parameters is also the key to ensure the surface quality of copper forgings. In the forging process, it is very important to control the process parameters such as melting temperature, pouring temperature and cooling speed. Reasonable process parameters can reduce metal defects such as pores and inclusions, so as to improve the surface smoothness and finish of copper forgings. In addition, maintaining good temperature control can also prevent the polar phenomenon of copper forgings, avoid surface oxidation and corrosion conditions.

Metal purification is also one of the important means to improve the surface quality of copper forgings. Pretreatment of copper materials with metal cleaning agents can effectively remove surface pores, impurities and casting residues, making metal materials more pure. By purifying treatment, the incidence of surface defects of copper forgings can be greatly reduced and the stability of surface quality can be improved.

Surface treatment is a key step to improve the surface quality of copper forging. By polishing, pickling and other surface treatment methods, can remove surface rust, oxide layer and other pollutants, improve the surface flatness and finish of copper forging. In addition, sandblasting, shot blasting and other technologies can also be used to increase the surface roughness of copper forgings, improve adhesion and coating effect, so that it has better corrosion resistance and wear resistance.

In order to ensure the stability and consistency of the surface quality of copper forgings, appropriate detection means should be equipped. Metallographic microscope, scanning electron microscope, hardness tester and other testing equipment can detect the surface of copper forgings comprehensively, and accurately find and analyze the surface defects. At the same time, it is also very important to establish a scientific quality management system. In the quality management system, the corresponding process and quality standards should be set up, and the key control points in the production process should be defined to ensure that each process meets the quality requirements.

In addition to the above technical means, training and technical support are also necessary to improve the surface quality of agricultural copper forgings. By strengthening the staff’s skill training and providing the necessary technical support, it can improve the professional level and work efficiency of the operator, ensure the operation standard, and improve the stability and consistency of the surface quality of copper forgings.

In summary, the surface quality control and improvement of agricultural copper forgings need to consider material selection, process control, metal purification treatment, surface treatment, testing means, quality management system, training and technical support and other aspects. By taking reasonable and effective measures, we can improve the surface quality of copper forgings of agricultural machinery, ensure its performance and service life, and provide reliable support and guarantee for agricultural production.
