Drawing Process
Drawing is
the process in which a red hot metal piece is beaten up by a hammer and the
thickness of diameter is decreased but length increased. The hammering is done
by placing the hot pieces on the anvil first, the road is subjected to a plastic
stage in the Furnace up to the desired length. The piece is kept on the horn of
the anvil or on the bottom part of following by hammering with the help of the
hammer. When the shape is round then it is converted into square-shaped by the face of the hammer and length is increased then it is converted into an octagon
shape and do the hammering regularly till the desired shape is achieved.
Upsetting
It is the process in which the diameter of the
hot workpiece is increased and length is reduced. The hot metal piece is placed
on the Anvil in a vertical position. It is struck with the hand hammer the hot
workpiece is held in a long time. During upsetting bending occur on the job in
such cases first the job should be straight and then upsetting should be
continued.
Punching Process
Punching is
the process in which a hole is made into the hot work piece. The job is heated
to the desired temperature and then it is placed on the hot metal piece with
the help of sledgehammer. The hammer is forced to piece the battle to half the metal
thickness then the punching is done.
Drifting
It is a
process of finishing and enlarging the hole. The process is similar to punching.
To continuous punching without using a die is called drifting but the tool is
used is known as Drift.
Swaging
The swaging
is a process of finish different shapes such a circular hexagonal and square. The workpiece is held in two part of the swages and after holding the piece the
hammering is done with the help of a hammer.
Fullering
The fullering
process is done on an anvil. The lower part of the fuller set is kept in the
whole of the anvil. The hot workpiece is placed in the groove on the lower
fuller. The hammering is done on the upper portion of fuller and workpiece is
placed on the fuller. The fullering is done for drawing and growing process. Bending
Bending is a
process which is commonly used for the forging process. It is simplest method of
bending a piece of metal in hand forging is to support it on the anvil. and hammering
on it When it is bent, the metal of the workpiece thins out round bend causing
weakness.
Forging Welding
The Forge welding the process of joining two
metal pieces by heating and hammering is known as Forge welding. The metal
pieces are to be welded are cleaned and heated in a furnace up to the welding
temperature then both pieces are heated up to the desired temperature and
picked from the Furnace with the help of tongue. The workpieces are placed on
each other and hammering is done on them and both the pieces get a weld.
