Abstract: The disclosure belongs to the technical field of die cleaning, and particularly relates to an automatic die cleaning device with reusable cleaning fluid. The automatic die cleaning device with reusable cleaning fluid comprises a robot, a cleaning fluid cyclic-spraying system and a die overturning mechanism. The automatic die cleaning device can spray the cleaning fluid to a die to clean oil stains off the surface of the wheel die, thus realizing the function of automatically cleaning the oil stains off the surface of the die; and the automatic die cleaning device also has the function of reusing the cleaning fluid, thereby saving the cleaning fluid and reducing the influence on the environment. The cleaned die surface is smooth, and the effect is ideal. The automatic die cleaning device reduces the labor intensity, meets the requirement of high-efficiency production, and improves the production efficiency.

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.
