Forging means a workpiece or blank obtained by forging and deforming a metal billet.
Forging can be used to apply pressure to metal blanks to cause them to deform and change their mechanical properties. Forging can eliminate the looseness and holes in the metal, thereby improving the mechanical properties of the forging.
Forgings have the following uses:
1）General industrial forgings refer to civil industries such as machine tool manufacturing, agricultural machinery, agricultural tool manufacturing and bearing industry.
2） Forgings for hydro-turbine generators, such as main shafts and intermediate shafts.
3） Forgings for thermal power plants, such as rotors, impellers, retaining ring main shafts, etc.
4） Metallurgical machinery, such as cold rolling rollers, hot rolling rollers and herringbone gear shafts, etc.
5） Forgings for pressure vessels, such as cylinders, kettle ring flanges and heads, etc.
6） Marine forgings, such as crankshafts, tail shafts, rudder stocks, thrust shafts and intermediate shafts, etc.
7） Forging machinery and equipment, such as hammer heads, hammer rods, hydraulic press columns, cylinders, and axle presses.
8） Modular forgings, mainly forging dies for hot die forging hammers.
9） Forgings for the automotive industry, such as left and right steering knuckles, front beams, car hooks, etc. According to statistics, forgings account for 80% of the mass of automobiles.
10）Forgings for locomotives, such as axles, wheels, leaf springs, locomotive crankshafts, etc. According to statistics, forgings account for 60% of the mass of locomotives.
11）Forgings for military use, such as gun barrels, door bodies, breech blocks, and traction rings, etc. According to statistics, forgings account for 65% of the mass of tanks.
Features:
1) Wide weight range. Forgings can range from a few grams to hundreds of tons.
2) Higher quality than castings. Forgings have better mechanical properties than castings and can withstand large impact forces and other heavy loads. Therefore, all important parts with high loads are made of forgings. [1] For high-carbide steel, forgings are of better quality than rolled products. For example, high-speed steel rolled products can only meet the requirements after reforging. In particular, high-speed steel milling cutters must be reforged.
3) Lightest weight. Under the premise of ensuring the design strength, forgings are lighter than castings, which reduces the weight of the machine itself, which is of great significance for transportation vehicles, aircraft, vehicles and space flight equipment.
4) Save raw materials. For example, for a crankshaft with a static weight of 17kg used in an automobile, when it is cut and forged by rolled products, the chips account for 189% of the crankshaft weight, while when it is die forged, the chips only account for 30%, and the machining time is shortened by 1/6. Precision forged forgings can not only save more raw materials, but also save more machining time.
5) High productivity. For example, two hot die forging presses can replace 30 automatic cutting machines to forge radial thrust bearings. When using an automatic top forging machine to produce M24 nuts, the productivity is 17.5 times that of a six-axis automatic lathe.
6) Free forging is highly flexible [6], so forging is widely used in some repair and manufacturing plants to produce various accessories.
