While working on a closed die, on squeezing the die the same shape which have been Digg on-die prints on the product, the extra material comes out from the die which is removed by the path of peripheral and being trimmed latter.
There are two main types of closed die forging come into know
1. Press forging
2. Drop forging
In press forging material is squeezed between dies very slowly with the use of mechanical press or hydraulic press. Because of its slow operation the final product comes with more dimensional accuracy and fine surface area is received.
Press forging is a method of forming a piece of metal into a specific shape by applying gradual pressure on a shaped die holding the metal. In closed-die press forging, the metal is completely enclosed in a die and pressure is applied on the die. Compared to open-die press forging, closed-die is an overall more efficient method with lower chance of error.
With press forging, the metal is shaped in a uniform way from the surface to the center. This means the impressions created are cleaned and the end product is generally stronger. Tongs are usually not required, and draft angles are not as frequently used. Initial setup costs are also higher with press forging, but the method becomes more cost effective as volume increases.
Compared to drop forging, press forging has the advantage of being more cost effective for higher volume runs, and also results in a stronger workpiece. It also retains the strength benefits of forging compared to casting.
In drop forging one material is put into the die and hammering action continues on the die anvil until it takes desired shape. Wrenches, piston and crankshaft are typical example of automobile parts made under forging operation.
Drop forging is a type of closed-die forging. It is used when a large quantity of certain components with sound and good quality forgings are to be produced.
The typical products obtained in drop forging are connecting rod, crank, crank shaft, crane hook, etc. Drop forging process is widely used in automobile industries, airplane parts manufacturing, rail road equipment manufacturing, engine manufacturing industries, agricultural equipment manufacturing industries, etc.
Process of Drop Forging:
The die used in drop forging consists of two halves. The lower half part of die is fastened to the anvil while the upper half part is fixed to the movable ram.
The heated bar or billet is kept in the lower die while the ram delivers four to five strokes (blows) on the metal. When these two die halves come together in closed alignment, the metal spreads and completely fills the die cavity.
