Die forging refers to the special die forging equipment use mould to make blank forming and forging method.
Under the action of external force, the metal blank to produce plastic deformation in the mould and the chamber is full of mold (mold cavity) in order to obtain the required shape and size of forgings forging method.
This method in the production of forgings dimension precision, small machining allowance, productivity high, the structure is more complex.In die forging hammer or the pressure in the forging die metal blank forging processing forming process.
Die forging technology of high efficiency, low labor intensity, size accurate, small machining allowance, and can be forged shape complex forging; Suitable for mass production.
But the mould cost is high, needs to have special forging equipment, not suitable for single piece or small batch production.
1 due to the mould chamber to guide the flow of metal, the shape of the forgings can be more complex.
2 the forging press forging streamline contours distribution within the forging, thus improve the mechanical properties and service life of the parts.
3 simple operation, easy to realize mechanization, high productivity.
