The forging material is mainly carbon steel and alloy steel components, followed by aluminum and magnesium, titanium, copper and its alloy material. The original state bar, ingot casting, metal powder and liquid metals. The metal in the cross sectional area and deformation mode after the break before the area is called the forging ratio. The correct choice of forging ratio on improving product quality, reduce the cost of a great relationship. Casting: the metal melt into liquid poured into the mold, the processing method of cooling and cleaning after the required shape of castings can be made into complex shapes. The workpiece, all types of objects.x0d forged delicate texture, good toughness, like women; casting out of shape workpiece, accurate size, small processing quantity, but black. Casting is within the mold casting, forging hammer is beatening by vigorously forging, stamping mold is a strong stamping.
State the loose metal welding holes, the mechanical properties of materials are generally better than the same forging casting. An important part of high load, harsh working conditions in machinery, in addition to relatively simple shapes can be rolled plates, profiles or welded parts, the forging forging press. Forming methods can be divided into: open (free forging forging). Using impact or pressure to the metal on the two against the iron (anvil) between the deformation required to obtain forgings, mainly hand forging and forging machinery two. The forging billet closed mode. The material in a certain shape of the die cavity in the compression deformation for forging, can be divided into forging, rotary forging, cold forging and extrusion. According to deformation temperature and forging can be divided into hot forging (recrystallization temperature processing temperature is higher than that of blank metal), warm forging (below recrystallization temperature) and cold forging (room temperature).
Forging: forging, metal after plastic deformation, a grain refinement in continuous fibers, so commonly used in key parts of Mao PI manufacturing, such as the axis, gear and so on. The casting of processed material is required, the casting performance generally of cast iron, aluminum and other good. Do not have many advantages of casting forging, but it can make complicated shape of zero, so commonly used in mechanical performance requirements of supporting the Mao PI manufacturing. Such as machine tools such as shell:.x0d forging hammer and other methods, the metal material in plastic state under a workpiece with a certain shape and size, and change its physical properties. Casting: heat the metal is poured in the mold or mold, after cooling solidification of.x0d forging is to become objects with mechanical metal into the shape you want, (cold, heat two methods.) casting: the metal is poured in to do The mold or mold, cooling after it is solidified into the shape you want: using.x0d forging of metal billets forging machinery pressure, the processing method of plastic deformation in order to obtain a certain mechanical properties, shape and size of forging forgings. Two part can be eliminated by forging casting.
