Overview
Roller forging machine is a kind of plastic change of billet by means of a pair of fan-shaped dies rotating in opposite direction.
In order to obtain the forging technology of the required forgings or billets. During the deformation process of roll forging,
After the blank is compressed by the roller forging die in the height direction, in addition to a small part of the metal flows laterally,
Most of the metal flows along the length of the billet.
Therefore, the essence of roll forging deformation is billet
The extended deformation process of the material under pressure is applicable to the process of reducing the cross section of the billet, such as the shaft
Class parts of the drawing, the slab of the grinding.
In industrial applications, roll forging can be used as die forging
The pre-blanks process provides blanks for long shaft forgings;
Also available on the roll forging machine
Realize the main forging forming process or direct roll forging.
Machine Feature
Roller forging technology has the characteristics of both forging and rolling, with high precision, small surface roughness and good quality forgings.
Because the metal fiber tissue is distributed according to the outline of the forging during roll forging,
Not cut off, uniform structure, good mechanical properties, precision roll forging without processing, to avoid the flow line cut or exposure of the disadvantage;
Roll forging continuous rotation, high production efficiency, set
The preparation structure is simple, the requirements for workshop and foundation are low, the die service life is long, the static pressure process during roll forging, the relative sliding between the metal and the die is less;
Required equipment tonnage is small because of roll forging
The process is a gradual and continuous deformation process. At each moment of deformation, the mold is only in contact with a part of the blank, so only the equipment with small tonnage is needed.
The process is simple, no
Shock, vibration, good working conditions, easy to achieve automation
