The manufacturing process of free forging mainly includes the following: Free hammer forging: The metal material is placed under the forging hammer, and the metal parts of the desired shape and size are processed by applying impact force and pressure to the material. This is the most common and traditional free forging process. Hydraulic forging: Hydraulic forging machinery is used to complete the forging process by applying high-pressure water flow to metal materials. Hydraulic forging can realize the machining of parts with complex shapes, and has higher accuracy and uniformity. Friction forging: Using the friction force in forging equipment, metal materials are forged between two friction surfaces. Friction forging has high production efficiency and forming capacity, which is suitable for mass production and complex shape parts. Robot forging: The use of robot system for free forging manufacturing, through pre-programming and control of the movement of the robot trajectory and strength, to achieve the deformation and formation of metal materials. Robot forging has the characteristics of high automation, flexible production and precise control. The characteristics of free forging are as follows: high flexibility: compared with die forging, free forging does not need to rely on fixed molds, and can flexibly adjust and transform the shape and size of the forming, to adapt to the manufacturing needs of various complex products. High production efficiency: The free forging process usually has a high-speed impact force and pressure, which makes the metal material complete the molding in a short time, improving the production efficiency. Good mechanical properties: In the forging process, the metal materials are refined and the mechanical properties are improved, which makes the forgings have better strength, toughness and fatigue properties. High precision: Because free forging has no mold restrictions, high precision requirements can be achieved by controlling forging parameters and processes to meet the needs of different engineering applications. Saving resources: Free forging saves the manufacturing and maintenance costs of the mold, effectively saving resources and cost input. In general, free forging has the characteristics of flexibility, efficiency, high mechanical properties and high precision, and is widely used in aerospace, automotive, shipbuilding, petrochemical and other industries.
