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.
