Forging production is one of the main processing methods for providing mechanical parts blanks in the machinery manufacturing industry. Through forging, not only the shape of mechanical parts can be obtained, but also the internal structure of the metal can be improved, and the mechanical and physical properties of the metal can be improved. Generally, for important mechanical parts with high stress and high requirements, most of them are manufactured by forging production methods. Such as steam turbine generator shafts, rotors, impellers, blades, guard rings, large hydraulic press columns, high pressure cylinders, rolling mill rolls, internal combustion engine crankshafts, connecting rods, gears, bearings, and artillery in the defense industry and other important parts are forged. Production.  Therefore, forging production is widely used in metallurgy, mining, automobiles, tractors, harvesting machinery, petroleum, chemical industry, aviation, aerospace, weapons and other industrial sectors, even in daily life, forging production also plays an important role. In a sense, the annual output of forgings, the proportion of die forgings in the total output of forgings, and the size and ownership of forging equipment reflect a country's industrial level to a certain extent.
