ABSTRACT:
A device for moving a blowing and spraying assembly for dies used in a forging press freely adjusts the movement of the blowing and spraying assembly. The distance from an intermediate fulcrum P of a driving lever 2 having a certain length L to a pressure receiving roller 21 located at one end of the lever 2 being in contact with a slide 11 is established as L1, and a distance from the fulcrum P to an engagement ring 31 located at another end of the lever 2 is established as L2. The distances L1 and L2 can be freely adjusted by changing the position of the point P. The engagement ring is engaged with a linkage 5 through a connecting part 4, and a driven lever 51 of the linkage is connected to the spray blower. When changing the ratio of L1 to L2, an inclination .theta.1 of the driving lever is increased or decreased, and this variation of the inclination causes an inclination .theta. 2 of a driven lever to change, whereby a stroke S of a jet 61 on the top end of the spray blower is changed. For replacing a die after completing one lot of forging, the function of spray blowing may be simply adjusted so as to achieve an optimum lubrication and cooling.
