LITAI Technology Information: The manufacturing process of forging products is centered on the plastic deformation of forgings and consists of a series of processing procedures. Quality inspections are conducted at each processing stage and before the forgings leave the factory. The inspection items include the shape and size of the forgings, surface quality, metallographic structure, and mechanical properties, etc. The specific items are determined based on the requirements of semi-finished products and the forgings themselves during the processing stages.
1) The pre-processing before forging deformation mainly includes the blanking and heating processes. The blanking process prepares the original blanks according to the required specifications and dimensions for forging. If necessary, the original blanks also need to undergo treatments such as rust removal, surface defect removal, anti-oxidation and lubrication; the heating process heats the original blanks according to the heating temperature and production rhythm required for forging deformation.
(2) Forging Deformation Process: On various forging equipment, the blank undergoes plastic deformation to meet the basic quality requirements for the internal and external aspects of the forged piece. This process may involve several procedures.
(3) Post-forming process after forging: After forging, the next step is the cooling process of the forged piece. Subsequently, in order to make up for the deficiencies of the previous processes and ensure that the forged piece fully meets the requirements of the forging product drawing, a series of processes such as edge trimming and punching (for the forging die), heat treatment, correction, and surface cleaning are required. Sometimes, the post-cooling process after forging is closely combined with the heat treatment process to obtain specific forging microstructure and properties.
The essence of forging is that through the application of external force by tools or molds to the blank, the blank absorbs mechanical energy and undergoes changes in the distribution of stress states within it, resulting in the displacement and deformation flow of material particles; for hot forging, the blank also absorbs heat energy due to heating and generates corresponding temperature distribution changes within it. Under the drive of mechanical force and heat energy, the blank undergoes changes in its appearance shape, size, as well as internal structure and properties.
The operation process of the forging production line is lengthy and the procedures are complex. By using robots to connect each process, not only is the automation demand fulfilled, but also the real-time monitoring of the online equipment status, operation conditions and process parameters is enhanced. Through in-depth cooperation between informatization and industrialization, the ultimate goal of cost reduction, efficiency improvement and labor liberation is achieved.
