The Production Process Of Fan Shaft Forged Blank
1. Material selection: The fan shaft forged blank is usually made of low-alloy structural steel. This alloy has good strength, toughness and fatigue properties. These materials undergo rigorous chemical composition analysis to ensure that they meet the requirements of forging processing.
2. Forging processing: forging is the process of applying pressure to the metal blank at high temperature to produce plastic deformation to obtain the required shape and mechanical properties. Its forging process consists of upsetting, drawing, punching, and other steps to remove excess metal and achieve the desired size and shape. Alternatively, in the forging process, workers can also use two points to forge one side and then carry out the final forging by flat forging. This can improve the dimensional accuracy and surface roughness of the shaft diameter.
3. Heat treatment: after forging, the forging blank needs to be heat treated to improve its structure and performance. The heat treatment process includes steps such as annealing, normalizing, quenching, etc. It aims to improve the hardness, red hardness, and fatigue strength of the material.
4. Inspection and quality control: after forging and heat treatment, workers need to test it. This ensures that it meets the drawing requirements. The inspection includes the inspection of diameter size, surface quality and metallographic structure. At the same time, it is necessary to grind and polish the forging blank to improve its surface roughness.
