PURPOSE:To provide the titled press die elevating the correction effect in the plane accuracy of the elastic deformation part of a press component by placing a press component on a forming edge stand forming recessed or projected face on the necessary part of the top face and by pressing a waffle die of the forming edge from the upper face of the press component. CONSTITUTION:A press component 1 is mounted on a forming edge stand 3 forming a recessed face 3b by cutting to the necessary depth B on the top face corresponding to the press component 1 having a mirror face part 1a deformed to projected shape by elastic deformation. When said mirror face part 1a is pressed with a waffle die 2a of a forming edge 2, the mirror face part 1a is fitted to the recessed face 3b and is deformed with the encroachment of the edge 2a, while it is bent deeply to the lower part further than the engaging part of a flat face 3a, and the correction effect is elevated. If, however, the mirror face part 1a of component 1 is deformed to recessed shape, the necessary part of the top face of the forming edge stand 3 is formed to a projected face shape. |
