Forging has been a popular method of metal shaping since the early ages. Earlier, the blacksmiths used to shape hot metal pieces with hammers.
But nowadays, metal forging relies more on machinery than hand tools. Different forging presses exert varying pressure and form different metal shapes.
Read till the end to know more about forging presses and the best forging unit for all industrial applications.
What is a Forging Press?
A forging press exerts pressure on the dies to form the shape of the metal piece. The forging press has a vertical ram that exerts pressure to hold the die in place.
The forging press exerts a slow pressure rather than strong and continuous blows. It makes the dies go deeper into the metal piece.
It may be done using mechanical or hydraulic forging and for both open and closed-die forging.
Different Techniques of Press Forging
The main difference between open-die and closed-die press forging is the placement of dies.
In open die press forging, the die is placed on one side of the metal piece. Whereas in closed die press forging, the metal piece is surrounded by die on all sides.
Closed die press forging is the best technique to fabricate coins to obtain the minute details of the die.
Different Types of Forging Presses
The three forging presses include:
- Mechanical Press
The electric motor provides the energy stored in the rotating flywheel. The mechanical press converts the rotational motion into the linear motion of the ram.
The stroke starts working on a set speed, length, and duration. Due to the set requirements, mechanical presses offer high productivity and accuracy.
Working on the mechanical press does not require highly skilled labour. The lift-out pins in the mechanical press automatically remove the die from the forged piece and are thus suitable for low-profile metal forgings.
- Screw Presses
Screw presses convert the kinetic energy to linear energy for the ram.
The screw presses have vertically mounted drive wheels that are shifted to accelerate the ram downwards.
The screw presses are of two types- friction drive machines and direct electric drive machines. The electric drive machines have a screw threaded to the ram, which does not use tons of energy, unlike the friction drive machines.
The amount of linear energy produced depends on the kinetic energy supplied to the flywheel.
- Hydraulic Presses
Hydraulic presses have a slower speed than the other forging presses. They are best suitable for open die forging of large aeroplane parts.
These machines work best with a water hydraulic system. The time of contact between the ram and the metal depends on the different forging units and specifications of the end user.
However, the longer the contact time between the die and the ram, the lesser the die life.
For heavy industries, the die contact will be longer than others.
