Abstract

PURPOSE: To prevent a slippage of an outer plate from an inner plate by hemming the pre-hemmed outer and inner plates and also applying the coining getting from the bent part of the outer plate to the inner plate.
CONSTITUTION: In the lower part of a hemming punch 4 is provided a concave groove 5, into which a coining punch 6 is fitted. At the lower end of the coining punch 6, a conical projection 7 is provided. Pre-hemmed outer and inner plates 10 and 11 being placed on a supporting block 9, the coining is applied to the upper bent part 10' of the outer plate 10 by means of a pressure-welding device 8.
