[0019]
The hollow die 31B (FIG. 6A) is arranged one by one on both sides of the center die 31A, and eight segment dies 31C are arranged on the left and right sides, for example.
[0020]
A connecting member 10 is provided between the hollow mold 31B and the segment mold 31C (FIG. 6A) and between the segment molds 31C, as will be described later (FIG. 7B). The segment die 31C unnecessary for setting the top die length L (for example, the segment die 31C shown by hatching in FIG. 7B) is released outward by removing the connecting member 10. Yes.
[0021]
The center mold 31A having a different length a (FIG. 6B) is stored in a center mold rack 36 (FIG. 5) installed in the vicinity of the panel vendor . The number NO. Corresponding to the length a of the center mold 31A is displayed by the display means 35 described later. (FIG. 3) is displayed, the operator confirms the display, and the corresponding number NO. The center mold 31A is removed from the rack 36 and manually replaced.
[0022]
The center mold 31A has, for example, a minimum length MIN of 100 mm (FIGS. 3 and 6B), a maximum length MAX of 195 mm, and a pitch of 5 mm between them.
[0023]
Further, as described above, the center mold 31A is numbered corresponding to each length a (FIG. 3). For example, in the above example, numbers 1 to 20 are numbered.
[0024]
The correspondence (for example, table) between the length “a” of the center mold 31A and its number (FIG. 3) is stored in advance in the memory 4 (FIG. 1) as machine information, and is calculated by the calculation means 3 of the center mold 31A. When the length a is calculated, the CPU 1 (FIG. 1) refers to the memory 4 to detect the corresponding number, and the detected number is displayed on the display means 35.
[0025]
Further, the hollow die 31B has a length b of 185 mm (FIG. 6B), and the segment die 31C has a length c of 100 mm, both of which are unique to the panel vendor . Are stored in advance in the memory 4 (FIG. 1) as machine information.
[0026]
The length b of the hollow die 31B and the length c of the segment die 31C are both used for calculation by the calculation means 3 (step 102 in FIG. 8).
[0027]
The CPU 1 decodes and determines a program (for example, corresponding to FIG. 8) for carrying out the present invention, and controls the whole by giving instructions to each device such as the calculation means 3 and the display means 35.
[0028]
The calculation means 3 includes product information such as the bottom dimension and flange dimension of the workpiece W input from the input means 2 (FIG. 1), the minimum length MIN of the center mold 31A stored in the memory 4, Based on the machine information such as the lengths b and c of the punching die 31B and the segment die 31C, the die arrangement information when bending the workpiece W, for example, the length a of the center die 31A to be exchanged The numbers N1 and N2 of the segment molds 31C located on the left and right sides of the center mold 31A are calculated.
[0029]
Details of the calculating means 3 are shown in FIG. 2, and a top die length calculating means 3A, a center / segment mold total length calculating means 3B, a center mold length calculating means 3C, and a segment die number calculating means. It is configured by 3D.
[0030]
The top die length calculation means 3A calculates the top die length L corresponding to the length of the side of the workpiece W to be bent.
[0031]
For example, when machining the workpiece W shown in FIG. 7A, the sides (1) and (2) are already bent, and the side (3) is now bent.
[0032]
In this case, the CPU 1 detects the length of the side (3) as the bottom dimension of the workpiece W from the product information input from the input means 2, and corresponds to the length of the side (3) and the top die length. The length L (= 1700 mm) is calculated (step 101 in FIGS. 2 and 8 and equation (A) in FIG. 9).
[0033]
The center / segment mold total length calculation means 3B subtracts twice the length b of the hollow mold 31B from the top die length L to obtain the total length of the center mold 31A and the segment mold 31C. x is calculated.
[0034]
That is, the calculated top die length L includes all the lengths a, b, and c of the center die 31A, the hollow die 31B, and the segment die 31C.
[0035]
Accordingly, the CPU 1 detects the length b of the punching die 31B from the machine information in the memory 4, doubles the length b, and subtracts it from the top die length L, thereby obtaining the center die. The total length x (= 1330 mm) of only 31A and the segment mold 31C is calculated (step 102 in FIGS. 2 and 8, equation (B) in FIG. 9).
[0036]
The center mold length calculation means 3C uses the total length x of the center mold 31A and the segment mold 31C calculated by the center / segment mold total length calculation means 3B as the length of the segment mold 31C. The length a of the center mold 31A is calculated by adding the minimum length MIN of the center mold 31A to the remainder R divided by c.
[0037]
That is, if the total length x of the center mold 31A and the segment mold 31C is divided by the length c (= 100 mm) of the segment mold 3 is Q (= 13) and the remainder is R. X = 100 × Q + R, and R (= 30 mm) clearly occupies a part of the length a of the center mold 31A.
[0038]
Therefore, if the minimum length MIN (= 100 mm) of the center mold 31A is added to R, the length a (= 130 mm) of the center mold 31A can be calculated (step 103 in FIGS. 2 and 8). (C) in FIG. 9).
[0039]
The segment die number calculating means 3D divides the value obtained by subtracting the length a of the center die 31A from the total length x of the center die 31A and the segment die 31C by the length c of the segment die 31C. Is used to calculate the total number e of segment molds 31C, and the number N1, N2 of the left and right segment molds 31C is calculated based on the total number e.

[0041]
Among these, the total length calculation means 3D1 includes the total length x of the center mold 31A and the segment mold 31C calculated by the center / segment mold total length calculation means 3B, and the center mold length calculation means. By inputting the length a of the center mold 31A calculated by 3C (FIG. 2) and taking the difference (x−a) between them, the total length d (= 1200 mm) of the left and right segment molds 31C is obtained. It calculates (step 104 of FIG. 2, FIG. 8, formula (D) of FIG. 9).
[0042]
Further, the total number calculation means 3D2 divides the total length d of the left and right segment molds 31C calculated by the total length calculation means 3D1 by the length c of the segment mold 31C, thereby obtaining the left and right segment molds. The total number e of molds 31C is calculated.
[0043]
That is, in the present embodiment, as described above, the length c of the segment mold 31C used is 100 mm.
[0044]
Accordingly, the total number calculating means 3D2 can calculate the total number e (= 1200/100 = 12) of the left and right segment molds 31C by calculating d / 100 (FIG. 2, FIG. 2). 8 step 105, equation (E) in FIG. 9). .
[0045]
Further, the left / right number calculation means 3D3 rounds off the value obtained by dividing the total number e of the segment mold 31C calculated by the total number calculation means 3D2 into two, thereby obtaining the total number e of the number N1 on the right side of the segment mold 31C. The number N2 on the left side of the segment mold 31C is calculated by subtracting N1 from.
[0046]
That is, as described above, in this embodiment, since the total number e is 12, the value obtained by dividing the number is clearly 6 pieces. The number N1 of the mold 31C can be calculated (= 12/2 = 6 sheets), and the number N2 of the left segment mold 31C can be calculated (= 12-6 = 6 sheets) by the calculation of (e−N1) ( Steps 106 and 107 in FIGS. 2 and 8 and equations (F) and (G) in FIG. 9).
[0047]
If the total number e of segment dies 31C is an odd number, for example, 13 pieces, the number N1 (= 1) of the right side segment dies 31C is rounded off to the nearest half. 13/2 = 6.5 = 7 sheets) is calculated, and by subtracting this from the total number e, the number N2 (= 13−7 = 6 sheets) of the left segment mold 31C is calculated. Accordingly, in this case, the number N1 of the right segment molds 31C is increased by one.
[0048]
On the other hand, the ram 34 to which the top die 31 is attached (FIG. 1) is provided with display means 35.
[0049]
The display means 35 displays the number (FIG. 3) corresponding to the length a of the center mold 31A calculated by the calculation means 3 and the number N1, N2 of the segment mold 31C calculated by the calculation means 3, respectively. indicate.

That is, the CPU 1 determines the number NO. Corresponding to the length a (= 130 mm) of the center die 31A calculated by the calculation means 3. (= 7) (FIG. 3) is detected from the memory 4, and the number NO. (= 7) is added to the sequencer 6 (FIG. 1) together with the number N1 (= 12/2 = 6) and N2 (= 12−6 = 6) of the segment mold 31C calculated by the calculation means 3 in the same manner. Send.
[0051]
The number NO. Of the center mold 31A transmitted to the sequencer 6 is displayed. The number N1, N2 of the segment mold 31C is sent to the display means 35 through the I / O units 7 and 8 and displayed.
[0052]
The display means 35 includes, for example, a screen 35A and a lamp 35B (FIG. 1).
[0053]
