Composite hammer is very important in the process of production of one of the production technology of forging process and forging in many casting parts are made in the process, composite hammer head is not exceptional also, after casting this link, the use of the hammer head can significantly improve performance, today we mainly is to investigate the composite hammer forging process on the performance of what is important.
From the surface, composite hammer hammer hammer head is divided into two parts and hammer handle end, are to be highlighted, hammer and hammer handle is not the same kind of material that is used by the side of hammer handle because the requirement has strong robust performance, therefore generally choose carbon steel, high chromium cast iron is generally selected hammer side material.Prefabricated hammer and hammer handle, put it in the casting pouring in another kind of liquid metal casting molding.
Composite hammer head through forging can eliminate the metal smelting process of as-cast loose defects, such as optimizing the microstructure, at the same time because of the intact metal flow, forging generally better than that of the same material on the mechanical properties of the castings.
In addition, composite hammer forging to wear must choose the wear-resisting material, the service life of forging composite hammer head can achieve manganese steel, slide and so on service life of more than five times the original, namely the train wheels, hardness can be between 58 and 60, not easy to break, and high wear resistance, good impact resistance, strong toughness, and the use cycle is long, crushing efficiency more than 30%.Can be widely used in coke, coal, coal gangue, metallurgy, mining ore, lead and zinc tailings, cement limestone, clinker, brick shale and so on the many kinds of crushing industry.
