Spray head for supplying at least one die of a forming machine with lubricating coolant, and method for producing such a spray head

A production method for production of a spray head for cooling lubrication of at least one of an upper die and a lower die of a forming machine, the production method comprising:

• producing modules by additive manufacturing processes, wherein the modules comprise a nozzle body of a two-substance nozzle, channel walls of a plurality of feed channels comprising a first feed channel configured to supply a control fluid, a second feed channel configured to supply a spray medium, and a third feed channel configured to supply spray air, and a spray head foot comprising a supply connector;
• forming the spray head from the modules;
• and
• introducing the spray head into a working chamber between the upper die and the lower die between two working strokes;
• wherein the two-substance nozzle atomizes a mixture of the spray medium and the spray air onto the upper die or the lower die for cooling lubrication;
• wherein the two-substance nozzle is connected with the first, second, and third feed channels, the at least one two-substance nozzle being controllable by way of the first feed channel;
• wherein the first, second, and third feed channels extend to the spray head foot;
• wherein the supply connector is connected with the first, second, and third feed channels;
• and
• wherein the nozzle body is produced integral with the channel walls of the feed channels and/or wherein the channel walls of the feed channels are produced integral with the spray head foot.
