Abstract
Description
Technical Field
[0001] The invention relates to the technical field of metal forging, and in particular to a forging device. Background Art
[0002] Forging is a processing method that uses forging machinery to apply pressure to metal blanks to make them plastically deform to obtain forgings with certain mechanical properties, shapes and sizes. It is one of the two major components of forging (forging and stamping). Forging can eliminate defects such as loose castings produced during the metal smelting process, optimize the microstructure, and at the same time, because the complete metal flow lines are preserved, the mechanical properties of forgings are generally better than those of castings of the same material.
[0003] Carbonitriding is the process of simultaneously infiltrating carbon and nitrogen into the surface of steel forgings. Carbonitriding is also known as cyaniding. At present, medium-temperature gas carbonitriding and low-temperature gas nitrocarburizing (i.e. gas soft nitriding) are widely used. The main purpose of medium-temperature gas carbonitriding is to improve the hardness, wear resistance and fatigue strength of steel. Low-temperature gas carbonitriding is mainly nitriding, and its main purpose is to improve the wear resistance and seizure resistance of steel.
