The process of forming metal blanks with a forging die on a die hammer or press. Die forging process has the advantages of high production efficiency, low labor intensity, accurate size, small machining allowance and complex shape forging. Suitable for mass production. But the mold cost is high, need special die forging equipment, not suitable for single piece or small batch production.
1 The shape of the forgings can be complex, as there is a die chamber to direct the flow of metal.
2 The forging flow line inside the forging is distributed according to the forging profile, thus improving the mechanical properties and service life of the parts.
3. Simple operation, easy to realize mechanization, high productivity.
Free forging is the use of impact force or pressure to make the metal in all directions between the anvil face free deformation, without any restrictions to obtain the required shape and size and a certain mechanical properties of the forgings, referred to as free forging.
The characteristics of free forging are: simple tools and equipment used in free forging, good versatility and low cost. Compared with casting blank, free forging eliminates shrinkage cavity, porosity, porosity and other defects, so that the blank has higher mechanical properties. The forging is simple in shape and flexible in operation. Therefore, it has a special significance in the manufacture of heavy machinery and important parts.
