Abstract

Assuming at least any one of a punch and a die is a die to be measured, a press molding device has a distortion quantity measuring means, which is in stalled in the die to be measured and measures the quantity of distortion of the die due to press molding. When the die to be measured is located at the bottom dead center of molding, the distortion quantity measuring means is d isposed closer to the press side than the die shoulder R stop on the materia l outflow side. Assuming the radius of curvature of a curved profile on the surface of the die to be measured is R, the distortion quantity measuring me ans is preferably installed in a region of 10xR from the center of curvature of the curved profile.

Claims (8)

1. A press-forming device comprising:
a punch;
at least one die, as a mold to be measured, capable of moving relative to the punch, the mold being capable of forming a product having at least one curved surface; and a strain measurement means, arranged in the mold, for measuring a strain amount of the mold generated by press-forming, wherein the strain measurement means is positioned at the press-direction side relative to a radius end of a die shoulder on the material flow-out side when the mold is positioned at a lower dead point of press-forming.
2. The press-forming device according to claim 1, wherein the strain measurement means is positioned within a region defined by a surface which is away from the center of curvature of a curved surface of the mold by the distance ten times R, where R is a curvature radius of the curved surface.
3.. The press-forming device according to claim 1 or 2, wherein the strain measurement means is positioned a region near the center of curvature relative to surfaces each intersecting with each end portion of the curved surface of the mold and inclined, away from the curved surface, by 45 degrees relative to a normal line at each end portion.
4. The press-forming device according to any one of claims 1 to 3, wherein the strain measurement means is positioned away from a surface of the mold by equal to or more than 5 millimeters.
5. The press-forming device according to any one of claims 1 to 4, further comprising a blank holding die for applying a blank-holding force to a workpiece to be processed.
6. The press forming device according to any one of claims 1 to 5, wherein the strain measurement means is a piezoelectric element sensor.
7. A press-forming method using the press-forming device according to any one of claims 1 to 6, the method comprising:
judging that a product formed by the device is defective when a strain amount measured by the strain measurement means is above or below a predetermined range.
8. A press-forming method using the press-forming device according to any one of claims 1 to 6, the method comprising:
judging that the mold to be measured is defective when a strain amount measured by the strain measurement means is above or below a predetermined range.
