A separation device for detaching and stacking stamped sheet metal comprises a driving mechanism, a pushing mechanism, a lifting mechanism, a separating mechanism and a sheet metal supporting base. The sheet metal supporting base is used for supporting the other mechanisms and stacking the sheet metal. The pushing mechanism allows a pushing assembly to slide linearly in the horizontal guide direction of a guide support through a vertical slide rod connected with a cylinder so that the effect of pushing out the sheet metal on the top layer can be achieved. The lifting mechanism controls the guide support to rise and fall by adjusting the number of rotation circles of a screw so that a push block can always keep aligned with the sheet metal on the top layer when starting to work. The separating mechanism is connected to the lifting mechanism when a steel wire rope is wound around a pulley so that the separating mechanism can synchronously rise and fall together with the lifting mechanism under the influences of the gravity of the separating mechanism. A separating rod can prevent the sheet metal on the top layer from absorbing the sheet metal on the lower layer and sliding together with the sheet metal on the top layer, and a separating inclined block makes a gap formed between the sheet metal on the top layer and a sheet metal stack. The intermittent movement of the pushing mechanism and the lifting mechanism is achieved through double ratchets by means of the driving device. The separation device is easy to operate, high in efficiency, good in separation effect, high in flexibility and wide in applicability.
