Abstract
Provided a spray tray device capable of rotatably spraying a die lubricant, wherein a rotating driving mechanism drive the rotating shafts and the spray tray rotators to rotate, and several external nozzles are arranged on the spray tray rotators. The air pipe joints and the lubricant pipe joints respectively input compressed air and a lubricant into cavities, formed between the spray tray rotators and the connection sleeve bodies, through the nozzle connection pipes, and then the compressed air and the lubricant are sprayed out through the external nozzles. The device implements that the same dosage of the lubricant is uniformly sprayed into the surfaces of the maximum pitch circles of upper and lower dies.
