That is, when the die is the press drawing die shown in FIG. 4A, using the die data (parameters of each part of the die) A1, A2, B, H1, and H2,
L1 (open height) = A1 + A2 + B + H1 + H2
S1 (stroke length) = 2 × H1 + H2 + A2
S2 (approach position) = L1- (H1 + H2-thickness)
L2 (die height) = L1-S1
It becomes.
[0024]
Further, when the mold is the bending type shown in FIG. 4B, the mold data (parameters of each part of the mold) A1, A2, B1, B2, and H are used.
L1 (open height) = A1 + A2 + B1 + B2 + H + plate thickness S1 (stroke length) = H−plate thickness S2 (approach position) = L1− (S1−plate thickness)
L2 (die height) = L1-S1
It becomes.
[0025]
In addition, when the mold is the coining mold shown in FIG. 4C, the mold data (parameters of each part of the mold) A, B, C, and H are used.
L1 (open height) = A + B + C + H
S1 (stroke length) = H-plate thickness S2 (approach position) = L1- (S1-plate thickness)
L2 (die height) = L1-S1
It becomes.
[0026]
In addition, when the mold is an iron worker type, a saucepan type, a patch set type, or a tap type shown in FIG. 5, the mold data (parameters of each part of the mold) A, C, H, OH, SH are used.
L1 (open height) = C + A + H + OH
S1 (stroke length) = OH-SH + H
S2 (approach position) = default (none)
L2 (die height) = L1-S1
It becomes.
[0027]
Then, after all necessary items of motion data other than L1, L2, S1, and S2 displayed on the screen shown in FIG. 14 are input and “end of setting” is selected, the “type” shown in FIG. / Motion display screen ", and the operation screen shown in FIGS.
