Forging: mechanical pressure by forging the metal blank, so that it is plastically deformed to obtain a certain mechanical properties, shape and size of the forging certain processing methods. Two forging (forging and stamping) is one of the components. By forging can eliminate metal produced in the smelting process cast loose and other defects, optimize the microstructure, and because the preservation of a complete line of metal flow, the mechanical properties are generally better than the same material forgings castings. Related mechanical load is high, harsh working conditions of the important parts, in addition to simple shapes available rolled sheet, profiles or welded parts, the use of forgings. Liquid-liquid two-alloy composite casting: This is the latest technology is currently leading the industry, only a handful of domestic companies can produce, such as 嘉兴盛 good, Zhangjiagang Da, Hanson, the casting process for the introduction of two pressure-type liquid-liquid alloy centrifugal composite casting disadvantage hammer part is high hardness alloy steel, hammer handle part is excellent toughness of steel, the perfect combination of the two materials, solve a single alloy hardness hammer handle is easy to break, toughness really wear, wear is the current high manganese steel casting and forging track 3-6 times. Forging hammer crusher, the metal is heated up to a temperature of 700-1300 ℃, by forging mechanical pressure is applied to the metal blank, so that it is plastically deformed to obtain a certain mechanical properties, shape and size of the forging certain processing methods. Two forging (forging and stamping) is one of the components. By forging can eliminate metal produced in the smelting process cast loose and other defects, optimize the microstructure, and because the preservation of a complete line of metal flow, the mechanical properties are generally better than the same material forgings castings. Related mechanical load is high, harsh working conditions of the important parts, in addition to simple shapes available rolled sheet, profiles or welded parts, the use of forgings. In addition, forging hammer crusher wear and must be selected to be the most wear-resistant materials, wear-resistant materials currently used imported 65Mn, impact resistance, toughness, wear resistance, not easy to break. Forging production characteristics: 1. heated metal forging material into various shapes of tools, machinery parts or blank, that the forging. Forging metal materials can be changed within the organization, grain refinement to improve its mechanical properties. 2. You must use heating equipment forging, forging equipment and many aids. 3. The main steam hammer forging equipment, air hammer, hammer forging, mechanical hammer, hammer plywood, spring hammer, hammer belt, crank presses, friction presses, hydraulic press, reaming machine, roll forging machine.
