Abstract
PURPOSE:To prevent generation of the surface strain in embossing by forming the ordinary surface after a part to be embossed has formed with both an innerpunch and an embossing tool, which is protruded from a die excessively beforehand. CONSTITUTION:Prime material W is placed on a fixed female die 21 under a condition in which both an outer blank holder 24 and an inner punch 27 have ascended. The holder 24 is then so made to descend as to hold and clamp a circumferential part 26 of the material W between a protruding part 25 and a groove 26, as shown in the figure (a). At this time, the punch 27 is made to descend as a embossing tool 29 is made to protrude from forming surface of a female 21 by H the maximal dimension, then, an embossed part 2 is, as shown in the figure (b), formed onto the material W through both a recess part 30, which is provided onto the lower surface of the punch 27, and the tool 29. Then, as shown in fugure (c), the ordinary surface 1a is formed with both the lower surface of the punch 27 and the forming surface of the die 21. Thereafter, the holder 24 and the punch 27 are made to ascend together, then, thus formed product is taken out.
