Forging is a forming processing method that uses tools or molds to apply external force to metal blanks under impact or pressure to cause plastic deformation and change size, shape and properties, and is used to manufacture mechanical parts or part blanks. , forging is also called forging.
Forging has refined grains, dense structure, and can have coherent forging streamlines, which can improve the mechanical properties of the metal. In addition, forging also has the advantages of high productivity and material saving. Therefore forging plays an important role in metal thermal processing. This chapter mainly introduces the basic knowledge and forming methods of hot processing such as free forging, die forging and stamping.
Classification of forgings: Class I forgings: used to withstand complex stress and shock vibration, heavy load working conditions, and parts with limited design quality. Damage or failure of such parts will directly lead to serious consequences for the product and grade accidents. . Or although the part does not bear much force, damage will endanger personal safety, or cause system function failure and cause significant economic losses. Class II forgings: parts used to withstand fixed heavy loads and small impact and vibration working conditions. The failure or damage of such parts may directly affect the damage or failure of other parts and components. Once the parts are damaged during use, it will affect the normal operation of a certain part of the product, but it will not cause an accident or endanger personal safety, nor will it cause the system to fail. Class III forgings: Parts used to bear fixed loads but not to withstand impact and vibration working conditions. Damage to such parts will only cause partial failure of the product. Class IV forgings: used for parts with low load, low strength requirements, large safety factors and parts other than the above three types of parts.
Generally, steel forgings are sampled in the preparatory heat treatment state and subjected to prescribed heat treatment to inspect the mechanical properties, fracture surface, grain size, etc. For austenitic steel, high-temperature alloy, aluminum alloy, magnesium alloy, and copper alloy forgings, samples are taken directly from the forgings in the final heat treatment state to test the mechanical properties. For general steel parts, only normal temperature tensile and impact tests are performed. High-temperature alloy forgings must undergo high-temperature performance testing. Impact tests are generally not performed on high-temperature alloy, aluminum alloy, magnesium alloy, and copper alloy forgings. For austenitic steel high-temperature alloy forgings, fracture inspection is generally not performed. Alloy structural steel forgings must be inspected for intrinsic grain size.
Forgings need to be consistent from piece to piece, without any porosity, excess space, inclusions or other imperfections. This method produces components with a high strength to weight ratio. These elements are commonly used in aircraft structures. The advantages of forgings are extendable length, retractable cross-section, retractable length, extendable cross-section, changeable length, and changeable cross-section. The types of forgings include: free forging/hand forging, hot die forging/precision forging, upset forging, roll forging and die forging.
