Generally speaking, the forging process consists of the following processes: selecting high-quality blanks, heating, forming and cooling after forging. The forging process includes free forging, die forging and film forging.
In the process of flange manufacturing, because the quality and batch of forgings are different, different forging methods are selected. The productivity of free forging is a little low, and the machining allowance is large, but the tools are simple and versatile.
It is widely used to forge forgings with simple shape and small batch size. Free forging equipment, including air hammer, steam hammer, hydraulic press, etc., is suitable for small, neutral and other occasions.
Production and manufacturing of large forgings. Die forging production is efficient, easy to use, and convenient to complete mechanical automation and intelligence. The specification of die forgings is high precision, the machining allowance is small, and the fiber structure division is more scientific and reasonable.
