The radial forging hammer hammers the blank in multiple directions, so that the metal deformation is in the state of compressive stress; It is conducive to improving the metal plasticity, and can reduce and eliminate the radial tensile stress in the cross section of the blank
More +Aluminum alloy ring forging is a kind of forging whose metal is processed into rings during forging. Large annular forgings can be directly processed into parts, and also can be used for secondary processing as metal blanks. For example, the wind ring in the wind power generation industry, the steam seal ring of pressure vessels, the gear blank, the outer ring of bearings, and the joints of pressure pipes are all annular castings. Therefore, annular castings are widely used in the industry.
The machining allowance size analysis of aluminum alloy heavy forgings also has relevant requirements for the material of heavy forgings, and steel billets cannot be forged as forgings. For parts with different shapes, a certain forging ratio shall also be guaranteed. Round steel with similar dimensions shall not be used for forging production. There are strict requirements on temperature, forging frequency and pressure during forging processing.
Die forging can be divided into hot forging, warm forging and cold forging. Warm forging and cold forging are the future development direction of die forging and also represent the level of forging technology. According to materials, die forging can also be divided into ferrous metal die forging, nonferrous metal die forging and powder product forming.

Forging materials are mainly carbon steel and alloy steel, followed by aluminum, magnesium, copper, titanium and their alloys. The original state of materials includes bar, ingot, metal powder and liquid metal. The ratio of the cross-sectional area of the metal before deformation to that after deformation is called the forging ratio.
