Automotive forged parts are the most widely used components in the automotive industry. Their performance and quality are directly related to the safety, reliability and operating efficiency of vehicles. To meet the market demand for high-performance and high-quality forged parts, manufacturers are gradually adopting various advanced precision forming techniques.
- Precision Extrusion Forming Technique
Precision extrusion is a new forming method that uses two horizontally moving molds to extrude metal during the forging process of the forged parts. This method can produce axisymmetric or non-axisymmetric forged parts with different cross-sectional shapes. Compared with casting and forging, precision extrusion forming can greatly improve the forming accuracy and reduce subsequent processing procedures, while also emphasizing product appearance design and surface finish.
- Cold Heading Forming Technique
Cold heading forming technology is a process in which metal materials are formed by extrusion and other processes, and other technologies such as brazing, polishing are required for further processing, ultimately forming relatively complex forged parts. Cold heading forming has the advantages of high forming accuracy, small forged part deformation, high surface quality and high processing efficiency, thus it has been widely used in the automotive industry.
Case study: An automotive parts processing factory purchased two automatic cold heading production lines and used this technology to successfully produce various shapes of automotive bearing-related parts, such as rollers, tapered gears, etc. Compared with traditional mechanical processing methods, cold heading forming can not only reduce material waste, but also improve the processing quality and structural performance of finished products to achieve higher production efficiency and returns.
- Precision die forging technique
Precision die forging technology is a method of forming forged parts with precision molds. The characteristic of this technology is the high forming accuracy, which can produce forged parts of different sizes and complexities. At the same time, the surface quality of the formed product is excellent without causing any surface defects or residual materials. Precision die forging is mainly suitable for the manufacture of small precision parts.
Case study: An auto parts manufacturer imported precision die forging equipment from overseas for the production of high-precision components such as gears in transmission systems. Through comparative experiments, it was found that the formedForged parts showed high dimensional accuracy, good surface finish, could reduce material waste and improve production efficiency.
In summary, with the continuous promotion of the automotive industry, the precision machining technology of forged parts will continue to be updated and developed into more advanced technology methods to meet the upgrading quality and performance requirements.
