Abnormal Forging

Special-shaped forgings I. product introduction Special-shaped forgings are not ordinary forgings with different special-shaped forgings. Instead, they are forged according to the needs of machinery. Special-shaped forgings are widely used, because the parts of machinery are not completely regular in shape, but there are some special parts. Special-shaped forgings with ordinary forgings are to be carried out in the high temperature forging, so you can change the shape of the metal particles and tightness, which is able to change the density of the metal by the method of forging, increase the density of the metal at the time of use is not only the weight change, but also changed the hardness of the metal, usually by forging metal hardness has greatly increased. However, some metals become more brittle after being forged. Such metals do not bear great pressure when being used, but break when the pressure is too great. The special-shaped forgings usually adopt the method of free forging, because the shape is not special specification, so free forging can well reflect the advantages of forging. 2. Product parameters In the forging process of special-shaped forgings, free forging is generally adopted. Since the shape is not special, free forging can well reflect the advantages of forging without specific shape. Iii. Product advantages 1) wide weight range. Forgings can range from a few grams to a few hundred tons. 2) higher quality than casting. Forgings have better mechanical properties than castings, and can withstand large impact forces and other heavy loads. Therefore, forgings are used for some important and stressed parts. Forgings are of better quality than rolling for high carbide steel. Such as high-speed steel rolling (or forging) only after the change to meet the use requirements. In particular, HSS milling cutters must be forged. 3) least weight. Under the premise of ensuring the design strength, the forging is lighter than the casting, which reduces the weight of the machine itself, which is of great significance for vehicles, aircraft, vehicles and airborne instruments. 4) save raw materials. For example, the static weight of 17kg crankshaft used on the car, the use of rolling cutting forging, chip to account for the weight of the crankshaft 189%, and the use of die forging, chip only accounted for 30%, also shorten the machining time 1/6. Precision forging forgings, not only can save more raw materials, but also can save more machining hours. 5) high productivity. For example, two hot die forging press die forging radial thrust bearing can replace 30 automatic cutting machine tools. When M24 nut is produced by the head forging automaton, the productivity of the six-axis automatic lathe is 17.5 times. 6) free forging is flexible, so forging is widely used in some repair factories to produce various parts.
