[0017]
Next, the operation of the above embodiment will be described with reference to the display screens shown in FIGS.
[0018]
First, when the power is turned on, an initial screen (not shown) is displayed on the touch panel display (display means) 22 of the pendant operation panel 5, and subsequently, as shown in FIGS. 6 (press type) and FIG. 7 (vendor type). A 1P operation screen or a 6P operation screen as shown in FIG. 8 (press type) is displayed.
[0019]
Next, when “type / motion” is selected in the display state of the operation screen, a “type / motion display screen” as shown in FIG. 9 (press type 1P) is displayed. Subsequently, when "die number" is selected in the display state of the "die / motion display screen", a "die number selection screen" as shown in FIG. 10 (press die) is displayed. Subsequently, when the mold No. is "selected" in the display state of the "mold No. selection screen", a "mold information confirmation screen" as shown in FIG. 11 (press mold 1P) is displayed. Therefore, by checking all the mold information displayed on this screen, it is possible to confirm that there is no difference between the mold to be mounted and used and this mold information. Then, if "YES" is selected after confirmation, it is determined to select a motion program corresponding to the mold information.
[0020]
Thereafter, the display returns to the “type / motion display screen” shown in FIG. 9, and further returns to the operation screen shown in FIG. 6, FIG. 7, or the operation screen shown in FIG.
[0021]
On the other hand, if there is no data in the mold No., a “mold selection screen” as shown in FIG. 12 is displayed. FIG. 12 shows a state where the press die is selected. Then, a “type data setting screen” as shown in FIG. 13 (press type) is displayed. When all the items of the type data (A1, A2, B, H1, H2) displayed on this screen are input and “motion automatic setting” is selected, the screen shown in FIG. 14 (press die 1P) is displayed. Such a “motion data setting screen” or a “motion data setting screen” as shown in FIG. 15 (press die 6P) is displayed.
[0022]
At this time, the motion data of each of the items L1, L2, S1, and S2 displayed on the screens shown in FIGS. And is automatically calculated based on the mold data and a predetermined calculation formula corresponding to the shape of the mold. The calculation formula used at this time is determined as follows.
[0023]
That is, when the die is a press drawing die shown in FIG. 4A, the die data (parameters of each part of the die) A1, A2, B, H1, H2 are used.
L1 (open height) = A1 + A2 + B + H1 + H2
S1 (stroke length) = 2 × H1 + H2 + A2
S2 (approach position) = L1- (H1 + H2-plate thickness)
L2 (die height) = L1-S1
It becomes.
[0024]
When the mold is a bending mold 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 + thickness S1 (stroke length) = H-thickness S2 (approach position) = L1-(S1-thickness)
L2 (die height) = L1-S1
It becomes.
[0025]
When the mold is a 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 the case where the mold is an iron worker type, a saucepan type, a patch set type, or a tap type shown in FIG.
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, when 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 setting" is selected, the "type" shown in FIG. / Motion display screen ", and further returns to the operation screen shown in FIGS.
[0028]
In addition, necessary items of motion data including P1, P2, P3, P4, and P6 other than L1, L2, S1, and S2 displayed on the screen shown in FIG. 15 are displayed on the input screen shown in FIG. When "setting completed" is selected after all the information is used, the screen returns to the "type / motion display screen" as shown in FIG. 9 and further returns to the operation screen as shown in FIG.
[0029]
