Abstract: A forging and inclined window hole punching composite die includes an upper die holder, a connection sleeve, an upper die sliding sleeve, a pressure plate, inclined window puncher pins, a center puncher pin, first connection screw rods, first springs, second connection screw rods, second springs, hydraulic assistant systems, a lower die and a bottom plate. Bottom surface of the pressure plate of the composite die is a plane to avoid deformation of a front molding surface. Hydraulic power is added to the inclined window puncher pins to increase the pressure for punching inclined holes, avoid quality problems and increase a demolding force. A multi-split synchronous hydraulic device may well realize synchronization of the plurality of inclined window puncher pins.

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.
