Analysis of Forging Processing Technology Principles and Core Technical Points

Forging processing is a core manufacturing process that obtains parts with the required shape, size and performance by applying external force to cause plastic deformation of metal blanks. It is widely used in various industries such as machinery, mining, automotive, aerospace and so on. Mastering its process principles and core technical points is the key to ensuring forging quality, improving production efficiency and reducing processing costs. Combining with practical operation scenarios, this article sorts out the core content to help industry practitioners gain an in-depth understanding.

The core principle of forging processing is to utilize the plasticity of metal materials, apply external force through forging equipment to overcome the internal stress of the metal, make the blank undergo plastic deformation, and finally form the forging that meets the design requirements. Its core logic is "shaping + strengthening", which not only adjusts the shape of the blank through deformation, but also improves the mechanical properties such as strength and toughness of the forging through grain refinement during the processing. Compared with castings, forgings have a denser structure and more stable performance.

The core technical points mainly focus on three aspects. First, blank preparation: it is necessary to select a suitable blank according to the material and size of the forging, do a good job in cleaning and heat treatment of the blank, control the heating temperature within the optimal range of metal plasticity, and avoid forging defects caused by overheating and burning.

Second, forging process control: reasonably select processing methods such as hot forging and cold forging, accurately control forging speed, pressure and deformation, ensure the dimensional accuracy of the forging, and reduce problems such as cracks and deformation. Third, subsequent treatment technology: after forging processing, heat treatment, grinding, flaw detection and other processes are required. The mechanical properties of the forging are further optimized through heat treatment, surface burrs are removed by grinding, and internal defects are detected by flaw detection to ensure that the forging meets the service standards. In addition, equipment commissioning and operation specifications are also core points. Regular maintenance of forging equipment and standardized operation procedures can effectively improve processing stability and ensure the uniform quality of forgings.
