Forging is the collective name for forging and stamping. It is a forming processing method that uses the hammer, anvil, and punch of a forging machine or a mold to exert pressure on the blank to cause plastic deformation to obtain parts of the required shape and size.
Forging is the collective name for forging and stamping. It is a forming processing method that uses the hammer, anvil, and punch of a forging machine or a mold to exert pressure on the blank to cause plastic deformation to obtain parts of the required shape and size.
In the forging process, the blank undergoes obvious plastic deformation as a whole, and there is a large amount of plastic flow; in the stamping process, the blank is mainly formed by changing the spatial position of each part area, and there is no large-distance plastic flow inside it. Forging is mainly used to process metal parts, and can also be used to process certain non-metals, such as engineering plastics, rubber, ceramic blanks, bricks, and the forming of composite materials.
Forging and rolling, drawing, etc. in the metallurgical industry are all plastic processing, or pressure processing, but forging is mainly used to produce metal parts, while rolling, drawing, etc. are mainly used to produce plates, strips, pipes, etc. General-purpose metal materials such as profiles and wires.
Early stamping only used simple tools such as shovels, shears, punches, hand hammers, and anvils to shape metal plates (mainly copper or copper alloy plates, etc.) through manual shearing, punching, chiseling, and knocking. Manufacture of gongs, cymbals, cymbals and other musical instruments and pots. With the increase in the production of medium and thick plates and the development of stamping hydraulic presses and mechanical presses, stamping processing also began to be mechanized in the mid-19th century.
