I. Introduction
As an important part of the industrial field, high-precision metal tool forgings are widely used in automotive, aviation, energy, electronics and other fields. The production process of high precision metal tool forgings involves many links and key steps, and its manufacturing process and quality control are crucial to the quality and performance of products. This paper will introduce the manufacturing process and quality control method of high precision metal tool forgings in detail to provide reference for improving the quality and performance of forgings.
Second, material selection
The choice of materials for manufacturing high precision metal tool forgings is very important. Common raw materials include carbon steel, alloy steel, aluminum alloy, etc., these materials can achieve higher strength and hardness after proper heat treatment, to meet the requirements of high-precision metal tools forgings. In the selection of materials, it is necessary to consider the mechanical properties of materials, corrosion resistance, wear resistance, fatigue resistance and other factors. At the same time, for different application fields, it is also necessary to consider the performance of the material in terms of high temperature resistance, low temperature, corrosion and so on.
- Manufacturing process
The manufacturing process of high precision metal tool forging includes many links and key steps. The first is forging, that is, after heating raw materials to a certain temperature, forging and forming. In this process, factors such as temperature control, molding method and mold design need to be paid attention to to ensure the quality and accuracy of the forging. The second is heat treatment, that is, the forging is heated to a certain temperature, and the insulation and cooling are carried out to change the internal structure of the material and improve its mechanical properties. Then there is work hardening, that is, the forging is machined, such as cutting, grinding, etc., to further improve its accuracy and surface quality. Finally, quality inspection and optimization, that is, the appearance, size, surface quality, internal organizational structure and other aspects of the forging inspection and optimization, to ensure that its quality and performance meet the requirements. - Quality control
The quality control of high precision metal tool forging is the key link in the manufacturing process. In the aspect of appearance inspection, visual inspection and scanning inspection can be used to detect and control the surface quality, cracks and inclusions of forgings. In dimension detection, measuring tools and instruments can be used, such as calipers, micrometers, etc., to detect and control dimensional accuracy and form and position tolerance of forgings. In terms of surface quality, surface treatment technology and coating technology can be used to improve the surface quality and wear resistance of forgings. In terms of internal organization structure, metallographic inspection, non-destructive testing and other technologies can be used to detect and control the internal structure and defects of forgings.
V. Conclusion
As an important part of the industrial field, the manufacturing process and quality control determine the quality and performance of the product to a large extent. This paper introduces in detail the manufacturing process and quality control methods of high precision metal tool forgings, including material selection, manufacturing process and inspection optimization. In order to further improve the quality and performance of forgings, it is necessary to continuously strengthen the research and improvement of material selection and manufacturing process, while strengthening quality management and control to ensure the stability and reliability of every link. In the future, with the continuous development of science and technology, the manufacturing technology and quality control methods of high-precision metal tools forgings will continue to be promoted and improved, providing more powerful support for the development of the industrial field.
