The present invention relates to a chamfering device. The chamfering device comprises: a fixed block; a pressing block to move vertically above the fixed block; and a material transport unit to transport a plate on which a cylindrical workpiece is formed between the fixed block and the pressing block. A rotary die which rotates 180° at a time and has accommodation recesses formed on a first location below the workpiece transported with respect to the rotational center and on a second location being an opposite location of the first location is installed on the fixed block. A trimming punch to cut off the workpiece from the plate to place the workpiece into the accommodation recess at the first location is installed at a vertically identical location of the first location on the pressing block, and a chamfering punch to press the upper edges of the workpiece placed into the accommodation recess at the second location to chamfer the workpiece is installed at a vertically identical location of the second location on the pressing block. |
