What are the advantages and disadvantages of free forging classification?

One. Introduction to free forging
Free forging is a forging method that makes the metal between the upper and lower anvil iron produce plastic deformation under the action of impact force or pressure, so as to obtain the desired shape, size and internal quality forgings. Free forging in free forging, metal billet in addition to the metal contact between the upper and lower anvil iron is not subject to external restrictions, can be free deformation flow in all other directions, so can not control the development of deformation.
Two, free forging classification
In general, there are many types of free forging, such as hand forging and machine forging, among which:
1, hand forging: in general, hand forging can only produce small forgings, productivity is low;
2, machine forging: machine forging is the main method of quanshang free forging, with high processing efficiency, good processing quality and so on.
Three, advantages of free forging
Free forging can process shaft and rod forgings, ring forgings, cylinder forgings, bending forgings, special-shaped forgings and other types, with simple tools, strong versatility, short production preparation period and other characteristics. Free forging can be forged from one kilogram to two or three hundred tons of forgings, such as hydraulic turbine spindle, crankshaft, gear forgings, large connecting rod and other free forgings under large load at work, with high mechanical properties, free forging method can be used to produce free forging blank.
Four, free forging shortcomings
The shape and gear of free forgings can be controlled by manual operation, with low precision, large processing allowance, difficult production and processing shortcomings, so the forging threshold is higher, Quan Shang has a series of modern processing equipment, high processing quality, high production efficiency.
Five, the application of
Free forging can be used for the production and processing of large forgings and the trial production of new products as well as the production and repair of single and small batch forgings.
