Next, enter the data for section (3). In that case, enter the letters "SECTION (3)" in the section column as shown in the screen in Fig. 5, and then enter "SECTION (3)" in Fig. 2. Instead of displaying "Cross section image", enter the characters "end bend", and enter the end bend data in this field as follows. That is, as the corresponding side range indicating the range of the side of the section (1) where the section (3) is formed,
Input the numbers "2" and "4", and use "0.00" as the marginal dimension of the end bend shown in 3 in Fig. 6, and the length dimension of the end bend shown in 4 in the same figure. Enter "13.00" as the dimension of the parallel movement distance shown by 5 in the figure, and enter the starting point origin xy of the end bend part shown in FIG.

Next, enter the data for section (4). In that case, enter the letters "SECTION (4)" instead of the display "SECTION (3)" in Fig. 5 Enter the same data as shown.

When the above input is completed, the computer performs an operation to unfold and calculate the bent shape of the parting line 1, and the calculation result is recorded on a recording paper with an XY plotter, a printer, etc. and output.

The contents of the record include a development view scaled up at a parting line 1 (for example, scaled down at a ratio of 1: 3.16306) as shown in FIG.
As shown in the figure, the section (1) and section (2) show the turn order, bending direction, real angle, real length, and the dimension table showing the stop gauge dimensions in the press machine.
11 Section (1) and Section (2) as shown

And the developed drawing dimension table of parting 1 as shown in FIG.
As shown in the drawing, the development table coordinate table, as shown in FIG. 14, the full-scale development drawing of the section (3) and section (4) of the parting line 1 and the parting line 1 of the parting line 1 as shown in FIGS. The development drawing of the actual size consists of three drawings divided into three.

A marking line 6 is recorded in each of FIGS. 8 and 15 A, B, and C, and each marking line 6 is accompanied by a numerical value shown in the developed drawing dimension table shown in FIG. It Even if these values are recorded in a difficult-to-read state or the development view is recorded unclearly, it will be easily understood by looking at the development view dimension table of FIG. 12 and the development view coordinate table of FIG. In addition, in FIGS. 8 and 15A, B, and C, the chain line of the marking line 6 indicates a folding curve which is bent to one side by the press machine, and the broken line is a direction opposite to the folding direction of the chain line by the press machine. Each of the diagonal lines 7 and the numeral 8 attached thereto indicate a line and a numerical value for confirmation.
In FIG. 15A, B, C, the three drawings, a reference mark, for example, a key 9 is added for joining the three divided development views so as to join them into one development view. It

Next, the three drawings in Fig. 15, A, B, and C are joined to one drawing while matching the key marks 9 to each other, and the drawings are attached to the plate surface of the predetermined processed plate, and each marking line is attached. After scribing along 6, the stamping machine first punches out a prototype plate having an outer shape that conforms to the contour line of the above drawing, and then as shown in FIG. Bend along each of the bending directions along the lines to finish the shape plate 1 into the shape of the cutout 1.

In the above embodiment, an example of instructing only the bending process with the marking line has been shown, but the present invention is not limited to this, and depending on the product to be processed, the hole cutting with the marking line and other In some cases processing instructions are given.

The present invention is not limited to the above-mentioned embodiment, and is an expanded or reduced development drawing by an output device such as an XY plotter and a printer, which is output as a drawing divided into a plurality of sheets, and these drawings are joined. May be attached to the plate surface of the processed plate, or output with an output device such as an XY plotter and a printer as an expanded drawing of actual size, enlarged or reduced, and processed without dividing the expanded drawing. It may also be attached to the surface of the board.

〔The invention's effect〕

Since the present invention is configured as described above, it has the following various effects.

It is possible to output the developed view and the numerical value of the sheet metal product to be processed to the recording paper in any size of reduction, enlargement and actual size.

It is possible to divide the actual size development drawing of the sheet metal product to be processed into multiple drawings and output it, and add a joint mark to those drawings, so it is possible to represent even the largest product in the actual size development drawing become.

Accurate machining is possible without using expensive machine tools.

 No need for a dedicated draftsman.

Numerical calculation of the developed view and calculation of the bending order are not required, and the drawing is remarkably simplified, and the efficiency of the above-described conventional sheet metal working method can be significantly improved.

It is convenient to process an actual sample to be processed by sheet metal, when it is an expanded or reduced development drawing and the drawings divided into multiple sheets are joined and attached to the processed plate.
In addition, when pasting a developed drawing that has been output in full size, enlarged or reduced to the processing plate as it is, the developed figure fits on one sheet of recording paper, so compared to the case where multiple divided drawings are joined, It has an advantage that the work of attaching it to the processed plate can be omitted.
