Abstract

A spray head for suppling at least one die of a forming machine with lubricating coolant, said forming machine comprising a lower die and an upper die, is preferably produced by rapid manufacturing and is designed as a single piece to a large extent. The use of rapid manufacturing allows the production of the most varied configurations, such as stabilizing honey-comb structures or drip points, which allow a more advantageous design of the spray head.

5 . Spray head ( 10 ) according to claim 4 , wherein the two-substance nozzle ( 30 ) has a spray air outlet ( 33 ), which is configured as a de Laval nozzle ( 31 ).

6 . Spray head ( 10 ) for cooling lubrication of at least one die ( 20 ) of a forming machine ( 25 ), which machine has a lower die ( 21 ) and an upper die ( 22 ), in particular a die-forging press, which spray head is introduced into a working chamber ( 23 ) between the upper die and the lower die ( 21 , 22 ) between two working strokes, and carries at least one two-substance nozzle ( 30 ), which atomizes a mixture of spray medium and spray air onto the die ( 20 ) for cooling lubrication, and is connected with at least one feed channel ( 40 ), by way of which a control fluid, the mixture, spray medium or spray air can be supplied to the two-substance nozzle ( 30 ), and which reaches all the way to a spray head foot ( 50 ), which carries a supply connector ( 55 ), which is connected with the feed channel ( 40 ), in particular also in accordance with claim 1 , wherein a channel wall ( 41 ) of the feed channel ( 40 ) is configured as a pipe ( 42 ).

7 . Spray head ( 10 ) according to claim 6 , wherein the pipe ( 42 ) is configured to be inherently rigid and can carry itself and the two-substance nozzle ( 30 ).

8 . Spray head ( 10 ) according to claim 1 , wherein the two-substance nozzle ( 30 ) is connected with multiple feed channels ( 40 ).

9 . Spray head ( 10 ) according to claim 1 , wherein the spray head ( 10 ) carries at least two two-substance nozzles ( 30 ) connected with at least one feed channel ( 40 ).
