The forging method and Technology
There are two kinds of common forging method:
First, the forging:
In specific swaging forming the blank using a mold obtained by forging the forging method of the device. This method of producing dimensionally accurate forging, machining allowance is small, relatively complicated structure with high productivity.
Depending on the device, into the hammer forging forging crank press forging, flat forging machine forging, friction forging presses and the like. Hammer forging apparatus used for the forging hammers, typically air hammer forging, forging of a complicated shape, the first preliminary mold cavity formed in the preform, and forging die cavity.
Second, the free forging:
free forging using an impact force or pressure to deform freely in all directions between upper and lower anvil surface, the metal is obtained without any restriction of the a processing method required shape and size forging and certain mechanical properties, acronym free forging.
points hand free forging and forging machines consisting of free forging. Hand free forging low productivity, labor-intensive, only for repair or simple, small, small batch production of forgings.
In modern industrial production, free forging machine has become the main method of forging production, heavy machinery manufacturing, it has a particularly important role.
