Spray
Heads and Spray Plates
The actually spraying of the dies is performed by the spray
heads and spray plates. The task of the spray head with plates is to
clean the dies from dirt after each forging cycle by blowing compressed
air over the surfaces to clean them of scale and other debris, to cool
them with atomized lubricant, and to insure an optimum lubrication of
the forging die.

The spray heads are quick-connected to the end of the valve carrier
using a flange connection and convey the atomized lubricant from the
valve carrier to the spray plates.

The spray head is equipped with a special orifice which causes the lubricant
to be swirled around evenly distributing it over the entire surface of
the spray plate. The spray head is designed to convey the lubricant separately
to the upper and lower dies.

The spray plates are bolted to the spray head with standard bolts. The
spray plates have either round or square dimensions depending on the
geometry of the die and are designed specifically for rapid cooling and
lubrication of dies with large surfaces.

The spray plates are specially designed for the actual part and dies
being run. Machined into the surface of the spray plates are holes with
specific diameters and angles to hit the surface of the dies at the right
orientation with a required amount of lubricant. Special nozzles and
drillings can be installed onto the spray plate to spray into deeper
dies.
One spray head can be used and the spray plates changed for running
different parts.
