Abstract

The utility model relates to a hydraulic clamping feeding apparatus comprising roller tables on two sides and a feeding actuating mechanism. The feeding actuating mechanism comprises a supporting plate, a motor-driving portion and a clamping portion arranged on the supporting plate, gears and racks provided between the motor-driven portion and a frame. The feeding actuating mechanism is characterized in that the clamping portion is constituted by a bearer and a clamp mechanism; the clamp mechanism is constituted by a protruded holder with one end hinged on the bearer, an upper clamp body and a lower clamp body located on the protruded holder and a driving portion for the upper clamp body; the upper clamp body is constituted by a swing arm hinged on the protruded holder and an upper clamp jaw and a pendulum block respectively disposed on the front end and the rear end. The driving portion of the upper clamp body comprises an oil cylinder and an inclined block. The front inclined plane of the inclined block is in contact with the lower transverse plane of the pendulum block. The feeding device also comprises a detection composition detecting if the sheets are in place. By adopting the feeding device, the inclined block is pushed forward through driving the oil cylinder, which enables the pendulum block to drive the upper clamp body to reverse around the hinge point, thereby the upper and lower jaws close and clamp the sheet. The feeding device has an enhanced clamping force, prevents the sheet from dropping and ensures positioning precision.
