Abstract

Provided is a rotating spray device for a lubricant, wherein the rotating driving mechanism rotates to drive the rotating spindle, and the rotating spindle drives the upper and lower rotating spray trays to rotate, and compressed air and a lubricant are respectively fed into each pitch circle closed cavity formed between each of the rotating spray trays and the spray tray main body, and then are sprayed out through the nozzles on the rotating spray trays for uniform spray coating. The device can spray the same and uniform dosage of the lubricant to the working surfaces of the maximum pitch circles of upper and lower dies, play a role of uniform forging lubrication and reduce the forging defects.
