The advantages of forgings include stretchable length and shrinkable cross-section; Shrinkable length, stretchable cross-section; A length that can be changed, a cross-section that can be changed. The types of forgings include: free forging/hand forging, hot die forging/precision forging, top forging, rolling forging, and die forging.
(1) Large weight range. Forgings can vary from a few grams to heaps of tons.
(2) Higher satisfactory than castings. The mechanical homes of forgings are higher than these of castings, and they can face up to massive affect forces and different heavy loads. Therefore, forgings are used for all essential and burdened parts.
For excessive carbide steel, forgings have higher high-quality than rolled products. For example, high-speed metal rolled (or forged) substances can solely meet the usage necessities after change and forging. Especially high-speed metal milling cutters ought to endure forging modification.
(3) The heaviest is the lightest. On the premise of making sure plan strength, forgings are lighter than castings, which reduces the weight of the computer itself and is of wonderful value for transportation, aircraft, vehicles, and different aviation equipment.
(4) Save uncooked materials. For example, for a crankshaft with a static weight of 17kg used in automobiles, when the usage of rolled fabric for slicing and forging, the chips account for 189% of the crankshaft weight, whilst when the use of die forging, the chips solely account for 30%, which additionally reduces the machining time by means of 1/6. Precision solid forgings no longer solely retailer greater uncooked materials, however additionally keep extra machining hours.
(5) High productivity. For example, the use of two warm forging presses to forge radial thrust bearings can substitute 30 computerized slicing machines. When the use of pinnacle forging automated desktop to produce M24 nuts, the productiveness of the six axis computerized lathe is 17.5 instances higher.
(6) Free forging has wonderful flexibility, therefore, forging techniques are broadly used in some restore factories to produce more than a few accessories.
