With the rapid development of the manufacturing industry, the requirements for the refinement of forgings are becoming higher and higher. Although the traditional hot forging technology can meet the production demand to a certain extent, there are still some limitations in some aspects, such as dimensional accuracy and surface quality. The emergence of cold forging technology has opened a new chapter for the fine production of forgings.
Cold forging technology is a plastic deformation process of metal at room temperature, which has the advantages of complete grain structure, high dimensional accuracy and good surface quality. Compared with hot forging technology, cold forging technology can better maintain the integrity of metal materials, avoid problems such as grain growth and oxidation caused by high temperature, so as to obtain higher material strength and better mechanical properties. At the same time, because the cold forging process can achieve higher dimensional accuracy and better surface quality, finer and more complex forging products can be produced to meet the market demand for high-quality and high-precision forgings.
Application of cold forging technology in forging fine production
Precision parts manufacturing: In automotive, machinery, electronics and other industries, many precision parts need to be manufactured using cold forging technology. For example, automobile engine connecting rod, transmission shaft, etc., need to have high strength, high precision and good wear resistance, and cold forging process can meet these requirements, improve the performance and life of parts.
Micro-parts manufacturing: With the rapid development of microelectronics, biomedical and other industries, the demand for micro-parts is also increasing. Cold forging technology can manufacture small and complex parts, such as pins and connectors in microelectronic devices, as well as micro-surgical instruments in the biomedical field.
Complex shape forging manufacturing: Cold forging technology can produce complex shape forgings, such as blades, gears, etc. These parts are difficult or expensive to manufacture in the hot forging process, while the cold forging process allows for efficient, low-cost production.
High-performance material manufacturing: With the continuous development of new material technology, such as high-strength steel, aluminum alloy, etc., the application range of cold forging technology is also expanding. These new materials have better mechanical properties and processing properties, and through cold forging technology, finer and more complex forging products can be produced, improving product performance and safety.
