Abstract

PURPOSE:To perform accurate spotting of an upper die and a lower die, by detecting the directional alignment or misalignment of the detecting axis of the misalignment detector and a slide axis, and detecting the amount of misalignment of the upper die in the case of misalignment. CONSTITUTION:A cylinder 19 of the spotting device 10 is contracted. An up and down slide 21 is lifted and stopped at the position where a limit switch LSu is turned ON. A cylinder 50 is extended, and dummy mark 52a is aligned with the position of an upper die mark 61b. Then the position X1 of the mark 52a is detected by an ITV camera. Thereafter the slide 21 is lowered and stopped at the position where a limit switch LSd is turned ON. The dummy mark 52a is aligned with the position of the lower die mark 71b, and the position X2 of the mark 52a is detected. The axis of the detector DT is corrected so that the amount of the misalignment X1-X2 becomes zero. Thereafter, the upper die 60 and the lower die 70 are put in. The upper die is mounted on a compensating frame 32, and the lower die 70 is mounted on a truck 13. The marks 61b and 71b are detected, and the position of the upper die is corrected based on the amount of the misalignment. Thus the accurate spotting is performed.
