[Prior art]
In general, for example, processing for manufacturing a product is performed in a plurality of steps, but processing conditions between the processing are not considered at all. That is, when creating NC data for each NC machine tool in the automatic programming device, it is created for each process without reflecting the information between the processes.
[0003]
In addition, the automatic programming device operator may manually determine a special processing position (for example, a position of a joint or the like) by asking the bending operator the position where the product contacts the back gauge or the surface.
[0004]
On the other hand, the bending operator looked at the product after the cutting / punching process was finished, and judged whether or not the special processing point hit the back gauge (thereby creating bending data).

[Problems to be solved by the invention]
Such a conventional sheet metal working information creation method has the following problems.
[0006]
In other words, when bending a product, the product is positioned by applying the product to the back gauge. However, if there is a trace of joint processing at the location of the product applied to the back gauge, positioning is accurately performed. There was a problem that the product could not be made and the product would be defective.
[0007]
Also, the burr due to punching / cutting when the approach end point position for cutting the developed product shape comes into contact with the back gauge or when the die is overtaken is attached with the same accuracy. There was a problem that the product could not be applied and the product was defective.
[0008]
And there was a problem that it took time and effort for each operator to determine whether or not the specially processed portion hits the back gauge.
[0009]

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings.
[0017]
FIG. 1 shows a schematic configuration of a sheet metal working information cooperation system 1.
[0018]
The sheet metal working information linkage system 1 includes an automatic programming device 3, a laser processing machine 5, a turret punch press 7, and a bending machine 9. The communication cables 11 are connected to each other. In this example, the sheet metal processing information includes graphic data, bending processing data, cutting processing shape data, special processing position data, and the like.
[0019]
The automatic programming device 1 comprises a computer and includes input / output devices such as a mouse and a keyboard (not shown).
[0020]
Further, the automatic programming device 1 includes a display unit 13, a CAD / CAM unit 15, and a data creation management unit 17.
[0021]
The CAD / CAM unit 15 and the data creation management unit 17 are linked by a link unit 19. Thereby, the data creation management unit 17 can process / edit the data created by the CAD / CAM unit 15.
[0022]
The developed shape of the product created by the CAD / CAM unit 15 is stored in the graphic data memory 21 as graphic data. This graphic data consists of special processing (such as joint setting burrs, mold processing burrs, laser approach burrs, etc.) with cutting and punching projection shapes after processing the product, and the back gauge to which the product is attached. It plays the role of intermediate data that stores the mutual positional relationship. That is, NC data or the like is created from this graphic data.
[0023]
Here, a micro joint will be described as an example of the joint. This is a processing method in which the corner portion of the product is jointed by about 0.1 to 0.15 mm so that the product is not separated during the processing when the outer shape of the product is cut. This method eliminates the need to stop the machine each time for taking out the product, and greatly shortens the time when many small parts are taken from the material. It is also effective for maintaining the strength of the material being processed. The amount of joint that allows the product to be easily separated after processing is about 0.1 to 0.15, but this amount varies somewhat depending on the thickness and shape of the product.
[0024]
However, since a special processing mark such as the above-mentioned joint remains on the product, if this special processing mark is applied to the back gauge, accurate bending positioning is not performed and the product becomes defective. In this example, the processing information of each process is linked to automatically prevent the special processing portion and the back gauge from overlapping.
[0025]
The data creation management unit 17 includes an automatic cutting process shape creation unit 23 and an automatic bending process data creation unit 25.
[0026]
The automatic cutting shape creation unit 23 reads graphic data from the graphic data memory 21 and reads bending data from the bending data memory 27. Then, cutting shape data is created in which special machining positions (for example, joint position, approach end point, overtaking position, etc.) taking the back gauge position into consideration are specified on the graphic data. Subsequently, the cutting shape data is stored in the cutting shape data memory 29.
[0027]
Here, the special processing position is specified by automatic processing. However, for example, an operator or the like can specify and specify the special processing position from the display unit 13 with a mouse or the like.
[0028]
Thereby, versatility can be given to the determination of a special processing position.
[0029]
The automatic bending data creation unit 25 reads graphic data from the graphic data memory 21 and reads cutting shape data from the cutting shape data memory 29.
Then, special processing position data is extracted.
[0030]
Subsequently, the back gauge position is specified so as not to overlap the special processing position data, and is included in the graphic data. Bending data is created from the graphic data and stored in the bending data memory 27.
[0031]
Here, the back cage position is specified by automatic processing. However, for example, an operator or the like can specify and determine the back gauge position from the display unit 13 with a mouse or the like. Thereby, versatility can be given to the determination of a back gauge position.
[0032]
On the other hand, the bending data creation unit 31 is a processing unit that creates bending data in advance and stores it in the bending data memory 27, for example. That is, it is used when bending data is first created and then special machining position data is automatically created on the graphic data.
[0033]
The cutting processing shape data creation unit 33 performs processing for creating cutting processing shape data in advance and storing it in the cutting processing shape data memory 29. In other words, it is used when special processing data is first created as graphic data, and then the back gauge position is automatically specified to create bending data.
[0034]
The NC data creation unit 35 reads the bending data from the bending data memory 27 and transmits the NC data to the bending machine 9. Further, the cutting shape data is extracted from the cutting shape data memory 29, NC data of the laser processing machine 5, the turret punch press 7, etc. is created and transmitted to each machine tool.
[0035]
With reference to FIGS. 2-5, the operation | movement of the sheet metal processing information cooperation system 1 is demonstrated.
[0036]
Please refer to FIG. Here, processing for determining the special processing position (for example, joint position, approach end point position when processing with a laser processing machine, die overtaking processing position using a turret punch press, etc.) with bending data created in advance is described. To do.
[0037]
In step S201, a development view of the product is created and stored in the graphic data memory 21.
[0038]
FIG. 4A shows a development view of the product. In this example, in order to facilitate understanding, a development view in which a bend line 403a is provided in a square outer shape 401a will be described.
[0039]
In step S203, since the position of special processing is not determined on the development view of the product, the back gauge position is determined in an arbitrary position direction on the development view of the product (position information on the back gauge is reflected in the bending data). . That is, the special processing position is specified with reference to the bending processing data. The back gauge position is determined by, for example, the bending data creation unit 31.
[0040]
Here, FIG. 4B shows an example in which a product is applied to the back gauge.
[0041]
The product 401b is positioned by a back gauge 409b in order to bend the product 401b by a punch 403b and a die 405b at a bending position 407b. That is, the information that the back gauge hits the portion 411b where the back gauge hits the product is added. This information is also included in the bending data.
[0042]
In step S205, the contact position information in the bending data is added to the graphic data and stored in the graphic data memory 21. As for the bending process, the bending process is performed by creating control data for the bending machine with reference to the bending process data.
[0043]
In step S207, the automatic cutting shape data creation unit 23 reads and refers to the graphic data from the graphic data memory 21 (also refers to the bending data in the bending data memory 27 for the convenience of program processing), and specially places it at an arbitrary position. A processing position (for example, approach end point position, joint position, die overtaking processing position, etc.) is virtually created.
[0044]
In step S209, the automatic cutting shape data creation unit 23 determines whether the back gauge position and the special machining position created in step S205 (for example, the joint position) overlap. If it is determined that they overlap, the process proceeds to step S211. On the other hand, when it is determined that the position of the back gauge and the position of the joint do not overlap, the process proceeds to step S213.
[0045]
In step S211, the position of the special machining virtually set in step S207 by the automatic cutting machining shape data creation unit 23 is changed, and the process returns to step S207. And the position of special processing is virtually determined by the process of step S207. In other words, the position of the special processing is finally determined by performing the above-described processing until the position of the back gauge and the position of the special processing do not overlap.
[0046]
In step S213, the automatic cutting process shape data creation unit 23 reflects the determined position of the special process on the graphic data. Then, it is stored in the cutting shape data memory 29 as cutting shape data.
[0047]
Thereby, cutting shape data in which the back gauge and the special processing do not overlap is created.
[0048]
FIG. 5A shows an example in which the approach end point position on the product created by laser processing does not hit the back gauge.
[0049]
That is, an approach start point 505a and an approach end point 507a are created at locations that are not the back gauge contact position 503a in the product development diagram 501a. Here, it is created automatically, but it may be created by indicating the approach position from the display unit 13 with a mouse or the like.
[0050]
FIGS. 5B and 5C show examples where the joint machining position is created so as not to hit the back gauge.
[0051]
Reference is made to FIG. Joint machining positions 503b, 505b, 507b, and 509b are created on the outer periphery of the product development view 501b. However, referring to the bending processing data, the joint processing position 509b overlaps on the abutting surface 511b, so the automatic cutting processing shape data creation unit 23 changes the joint processing position 509b.
[0052]
FIG. 5C shows an example in which the joint machining position is changed. That is, since the joint processing position exists on the back gauge contact surface 511b, the joint processing position 509b is created on the side surface 513b of the product. As a result, the abutting surface 511b can be reliably positioned when contacting the back gauge.
[0053]
Please refer to FIG. Here, contrary to what was demonstrated above, the position of the special process etc. is determined previously, and the process which determines the position of the back gauge required for a bending process is shown.
[0054]
In step S301, a development view of the product is created and stored in the graphic data memory 21.
[0055]
In step S303, the cutting process shape data creation unit 25 determines the position of the special process. Then, the position information and the like of the special processing is reflected in the graphic data stored in the graphic data memory 21 and stored in the cut processing shape data memory 29.
[0056]
In step S305, the automatic bending process data creation unit 25 reads the graphic data to which the position information of the special process is added from the cutting process shape data memory 29, and determines the position so that the back gauge does not overlap the position of the special process. .
[0057]
Subsequently, bending data is created (at this time, the graphic data may be read from the graphic data memory 21 and referred to for convenience of program processing) and stored in the bending data memory 27. As a result, it is possible to create control data for the bending machine from the bending data and perform actual machining.
[0058]
In step S307, the determined back gauge position information is reflected in the graphic data and stored in the graphic data memory 21.
[0059]
In addition, this invention is not limited to the example of the embodiment mentioned above, It can implement in another aspect by adding an appropriate change.
[0060]
【The invention's effect】
As described above, according to the system of the present invention, that is, when creating bending data with an automatic programming device, a back gauge position (applying position) and a special processing position (for example, a joint at the time of cutting or punching instruction) Position, burr-free machining position, approach position, etc.), and process to avoid applying special machining to the place where it touches the back gauge, or in the reverse flow, do not apply the back gauge to the position where special machining is applied There is an effect that can be considered.
[0061]
It is said that it is possible to automatically create data for the primary processing considering the secondary processing without having to check the product (position to be applied to the back gauge and joint position) between the automatic programming device operator and the bending operator. effective.
