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: A device for removing burrs from a back cavity of a wheel includes a lower lifting synchronous movement arrangement, an outer ring brush arrangement, an inner ring brush arrangement, a synchronous movement arrangement and an upper lifting drive arrangement. When the device is used, an upper cylinder drives four clamping blocks to clamp the wheel synchronously through an upper guide rail, an upper gear and upper racks; an upper cylinder drives the wheel to rise and separate from a roller bed through upper guide pillars and upper guide sleeves; an upper servo motor drives the clamped wheel to rotate through an upper rotating ring. The present invention can be used for not only polishing the burrs at the back cavity of the wheel, but also accurately adjusting the position of each brush according to the flange size and the back cavity diameter of the wheel.
