The exquisiteness of die forging technology: Who said metal processing is simple?
Die forging is an ancient and classic metal processing technology. After thousands of years of development and evolution, it has now become an indispensable and important link in the manufacturing industry. Its exquisiteness is not only reflected in the maturity of the technology and the complexity of the process, but also in the sophistication and precision of its process.
In the die forging process, choosing the right material is a crucial step. Different materials show different characteristics during the die forging process, such as strength, plasticity, etc., so the materials need to be selected according to the requirements of the final product. Generally speaking, common die forging materials include steel, aluminum, copper, etc. After selecting the material, strict preparation work is required, including preheating, cleaning, etc., to ensure that the material has good processing performance and surface quality.
The mold used in the die forging process is crucial, as it directly affects the shape, size and surface quality of the final product. Therefore, the design and manufacturing of molds require careful calculation and processing. Modern mold design usually uses computer-aided design (CAD) and computer numerical control processing (CNC) technology, which can realize mold manufacturing of complex shapes and improve the accuracy and stability of the mold.
During the die forging process, materials usually need to be heat treated and preheated to increase their plasticity and reduce deformation resistance. Heat treatment usually includes annealing, normalizing and other processes, which can improve the structure and performance of the material. Preheating is to heat the material to a certain temperature to facilitate subsequent forging operations. By precisely controlling heat treatment and preheating parameters, the quality and formability of
die forging products can be effectively improved.
Die forging processing is the core part of the die forging process. Its exquisiteness lies in the precise control of parameters such as force, speed and temperature. During the die forging process, mechanical pressure or hydraulic pressure is usually used to press the heated metal blank into the shape of the mold to achieve product shaping. In this process, the processing parameters need to be accurately controlled according to the characteristics of the material and the requirements of the product to ensure the dimensional accuracy and surface quality of the product.
After the die forging process is completed, the product usually needs to be cooled and tempered to eliminate residual stress and improve the strength and hardness of the material. Cooling usually uses water cooling or air cooling, while quenching and tempering involves heating the product to a certain temperature and then performing insulation and quenching treatments. Through reasonable cooling and tempering processes, the mechanical properties and durability of die forged products can be improved.
The key to the exquisite process of die forging products lies in the sophistication and precision of each link. From material selection and preparation, mold design and manufacturing, to heat treatment, forging processing and cooling and tempering, each step requires careful planning and strict control to ensure the quality and performance of the final product. With the continuous advancement of science and technology and the continuous innovation of technology, I believe that the exquisiteness of the die forging product process will become more prominent, injecting new vitality and power into the development of the manufacturing industry.
