5.3. Setting up material
Before making the spiral tip is necessary to perform an operation to set up the material that are to work
with.
Since the spiral tip is a forging operation, we take for granted that the material will be red hot prior to defor-
mation.
To get a correct tip snail, we need to deform the material before placing in the machine, you will make a
small spiral start using the tool on the side of the machine, called "Starting Piece" identified in the section
1.3 of the manual. This is a small fold beginning 3 ÷ 4 mm in the direction of the spiral.
This part consists of several slots of different widths which allow us to bend the tip of the material to which
the beginning of the spiral is desired.
5.4. Sequence of performance
The operating sequence of the machine forging NARGESA PC16 starts at the moment you pressed both
operating controls together on the sides of the machine. If we keep only driven one of the buttons, the ma-
chine does not respond to commands.
Once the sequence is started, first clamping cylinder descends which we fixed the material into the proper
position. Then it will start the lowering and advancing of the zipper to perform spiral tip.
In the next picture we can see the time at which the fastener contacts the workpiece to be rolled.
