TECHNICAL FIELD OF THE INVENTION
The present invention relates to a sheet metal integration support system including a higher-level device and a lower-level device, and in particular, collects bending attribute information from a lower-level device in a higher-level device, creates development view data and three-dimensional view data using the bending attribute information, Related to a system that causes lower-level devices to use the data of (1).
[0002]
[Prior art]
In recent years, line control systems for machine tools (bending, laser, punching, etc.) have been advanced. In such a line control system, as shown in FIG. 7, an automatic programming device 1 (CAE) having a CAD / CAM function and a master device 2 as a server are arranged on the office side, and these upper devices and lower devices are arranged. A machine tool (NCT / laser, vendor) on the site, which is a device, is connected to the machine via a terminal 3, a terminal 4, and an NC device 5 via a LAN.
[0003]
The operator uses the CAD function of the automatic programming device 1 to generate a development view for obtaining a machining program for NCT / laser while imaging the three-dimensional shape based on the three-view drawing, and then generates the CAD by the CAM function. Appropriate tools are assigned to the developed view, or a laser trajectory is obtained, and these machining programs are transmitted to the master unit 2.
[0004]
An elongation value is used in generating the above-described development view. This elongation value is an elongation value selected according to the characteristics of the vendor of the user and the unique situation of the user with reference to an elongation value table or the like.
[0005]
That is, the developed view is because those generated for processing program for NCT / laser, not transmitted as it can not be used as it is for the vendor.
[0006]
One reason why this development is not sent is that it is said that the determination of the elongation value of the bending, the mold, the bending order, and the like cannot be determined without familiarity with the unique characteristics of the bender.
[0007]
For this purpose, the office gives the bending instruction and the three views to the worker on the site of the vendor, and the worker on the site gives the bending instruction, the blank material after NCT processing, and the three views. In addition, a bending line is drawn on a blank material in consideration of an empirical elongation value, and a bending order, a bending mold, and the like are determined. These decisions were made by workers at the site while imagining a three-dimensional shape from three views.
[0008]
Next, the worker at the site calculates the L value and the D value from the determined items such as the bending line, the bending order, and the bending die, and inputs the calculated values to the NC device 5. In obtaining the L value, the L value was input in consideration of the elongation value based on the dimensions of the three-view drawing.
[0009]
Then, the worker on the site side checks the dimensions and the bending angle of the product after bending with reference to the three views, and for example, when they do not match, the difference between the measured value and the predicted elongation value is calculated. It was reported to the office as the corrected elongation value.
[0010]
On the office side, when the corrected elongation value was reported from the site side, the development plan for the NCT / laser processing program was recreated by an automatic programming device to obtain a new processing program.
[0011]
[Problems to be solved by the invention]
However, in the past, despite the fact that an online system was set up, the bending attribute information measured at the vendor's site was not transferred online, and basically the extension value table provided at the office was used. Since a development view based on the elongation value determined based on the elongation value is generated, there is a problem that the development view is not an accurate development view in consideration of the elongation value according to the situation of the machine and the mold on the site side.
[0012]
That is, it is generated as development view data for obtaining a processing program for NCT / laser.
[0013]
For this reason, the NC device on the vendor side does not have a function of receiving graphic data such as a developed view or a three-dimensional view, nor does it have a function of transmitting attribute information measured on the site side.
[0014]
Further, in the automatic programming device, even if development data for generating a processing program for NCT / laser is obtained by a CAD function while imaging a three-dimensional shape, the development data is only sent to the CAM side. .
[0015]
Also, on the site side, since the graphic data is not sent from the host device side even though the online system is set up, the three-dimensional shape is obtained from the bending instruction handed over from the office side and the three-sided drawing. After obtaining a developed view while imaging, the L value, D value, etc. based on the developed view are input to the NC device to realize bending.
[0016]
That is, since no graphic data is sent, there is a problem that the worker on the site side must perform the work for obtaining the developed view and the three-dimensional figure twice.
[0017]
Further, when the corrected elongation value is reported from the site side, the operator on the office side has to recreate a development view for obtaining the machining program, so that there is a problem that the number of work steps increases.
[0018]
Further, since it is necessary to obtain a development view while imagining a three-dimensional shape based on the three views on the office side and the site side, there is a problem that a person who is highly skilled in bending sheet metal has to be provided.
[0019]
In addition, only the worker on the site side grasped the elongation value considered for inserting the bending line on the site side.
[0020]
The present invention has been made in order to solve the above-described problems, and collects the elongation value on the site side via a line, and obtains accurate graphic data on the host device side using the elongation value on the site side, It is an object of the present invention to obtain a sheet metal integration support system in which a lower-level device on the site side can use graphic data generated by a higher-level device.
[0021]
[Means for Solving the Problems]
The present invention is a sheet metal integration support system in which a lower device and a higher device connected to a machine tool are connected by a line.
[0022]
The upper-level device accumulates bending attribute information on the site side composed of extension value data and extension value information condition data of the work from the lower-level device side. A surface composite diagram in which the respective surfaces constituting the three-dimensional object are abutted with each other is generated and displayed, and the surface composite diagram is converted into a bending condition including the input bending direction, bending angle, joining condition, material, and attribute. After generating and displaying a three-dimensional figure bent based on the above, a development view in which the matching area of the surface composite view is removed is generated, and the figure data for generating the three-dimensional figure and the development view are respectively represented by : The bend attribute information of the matching area is added and transmitted to the lower order device.
[0023]
Lower device receives the graphic data from the host device, while interlocked displaying a developed view and a solid view of the graphic data, the bending attribute information field side regarding the graphic data inputted to the host device Forward.
[0024]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is a schematic configuration diagram of a sheet metal integration support system according to an embodiment of the present invention. The sheet metal integration support system shown in FIG. 1 connects an automatic programming device 10 having CAD and CAM functions, a parent device 11 as a server, an NC device 12 of a vendor, and a laser / NCT terminal device 13 via a LAN. The automatic programming device 10 has a function of transferring predicted bending attribute information and graphic data (development view data, three-dimensional view data). The master unit 11 collects and transmits bending attribute information (consisting of elongation value information condition data and elongation value data) from the NC device 12 and the automatic programming device 10 and transfers graphic data (expanded view data and three-dimensional view data). It has at least a collection and transfer function.
[0025]
The NC device 12 has a function of receiving graphic data and a function of transferring bending attribute information on the site side.
[0026]
This system uses the bending attribute information on the site side (extension value actually measured or elongation value determined by the operator) transferred from the NC device 12 of the vendor, or the predicted bending attribute obtained by the automatic programming device 10. Information is collected by the base unit 11 in the database 15. Further, the automatic programming device 10 reads the elongation value data of the master unit 11, and the CAD function uses the elongation value data to generate development view data and three-dimensional view data.
[0027]
The developed view data is final developed view data obtained by extracting the outer frame and the bend line of the combined surface diagram generated by matching the respective pieces of surface information constituting the solid based on the three-view diagram.
[0028]
Then, the CAM function generates a machining program such as a mold setup and a machining locus on the workpiece based on the development data. The base unit 11 stores the development view data, the three-dimensional view data, and the graphic data, and transmits them to the NC device 12.
[0029]
The above-mentioned processing program is transferred together with the processing schedule, and the development data is transferred together with the processing schedule and the three-dimensional view data.
[0030]
The automatic programming device 10 inputs and displays each surface constituting the three-dimensional object input based on the three-view drawing, and generates a surface composite diagram according to designation of a joint portion on each surface on this screen. In addition to the display, the three-dimensional figure obtained by bending the surface composite diagram is displayed on the screen in conjunction with the input of the bending direction, the bending angle, the joining condition, and the material attribute (hereinafter, generally referred to as bending condition Ki).
[0031]
This three-dimensional figure is searched for whether or not there is bending attribute information (elongation value or predicted elongation value on the site side) that matches the bending condition Ki from the base unit 11, and if there is matching bending attribute information, the bending is performed. After obtaining the surface composite diagram of the overlap region of the elongation values included in the attribute information, a three-dimensional diagram (surface model) obtained by bending the surface composite diagram based on the bending condition Ki is generated and displayed.
[0032]
If there is no bending attribute information matching the bending condition Ki in the base unit 11, an elongation value is obtained from the bending condition Ki by FEM (elasto-plastic finite element method), and a surface composite diagram is formed using the predicted elongation value. At the same time, the predicted bending attribute information is transferred to the parent device 11 and stored.
[0033]
In addition, editing of the interference part of the three-dimensional diagram, dimension calculation display of the three-dimensional diagram, and reverse simulation processing are performed, and after correcting the above-described surface composite diagram from these processing results, a processing operation of drawing the surface composite diagram with one stroke is performed. The obtained result is sent to the CAM as a final developed view (however, a bending line exists).
[0034]
Master device 11 is a server. The base unit 11 stores various files in a database 15. For example, a basic master such as predicted elongation value information, site-side elongation value information, machine information, mold information, bending information, material information, etc., and a component master including development view data, three-dimensional view data, processing data, processing schedule, and the like. Are stored in files. A part number is added to these data, and data having the same part number is centrally managed as a group.
[0035]
The NC device 12 accesses the master unit 11 to transfer the developed view data, schedule data, and three-dimensional view data with bend attribute (hereinafter, also collectively referred to as production information), and displays the developed view data on a screen. At the same time, a three-dimensional figure based on the three-dimensional figure data is displayed in a multi-window. That is, it has a function of displaying the developed view and the three-dimensional figure of the developed view in conjunction with each other.
[0036]
Further, the NC device 12 has a simulation function, and when the bending order based on the developed view data and the three-dimensional view is determined, the L value and the D value of the bending line position at the place of the bending order are determined and specified. Have the bender actually perform the processing while performing the bending simulation with the mold. In addition, the elongation value is obtained by calculating backward from the L value.
[0037]
In addition, the NC device 12 has a function of transferring an elongation value, and transfers the elongation value to the base unit 11 in response to input of a save instruction. That is, the elongation value according to the situation on the site side is transferred.
[0038]
The aforementioned elongation value is included in the bending attribute information managed by the bending elongation ID, as shown in FIG. A machine number is added to the bending attribute information. The bending attribute information includes a material name, a bending angle, a bending type (direction), an inside R value , a punch ID, a die ID, a predicted value, or an elongation value including a calculation / manual input flag indicating whether or not a bending attribute on the site side. It comprises an information condition part and an elongation value data part comprising an elongation value, a bending load, a springback amount and the like.
[0039]
(Detailed configuration of each part)
FIG. 3 is a detailed configuration diagram of each unit of the sheet metal integration support system according to the embodiment. In this drawing, the automatic programming device 10, the parent device 11, and the NC device 12 will be described.
[0040]
The automatic programming device 10 includes an elongation value data reading unit 20, a finite element method unit 21 (FEM), a surface synthesizing unit 22, a three-dimensional plotting unit 23, a developed view generating unit 24, a graphic editing unit 25, And a CAM unit 26. The automatic programming device 10 has a function of transmitting or receiving data with a predetermined network OS (for example, windowsNT).
[0041]
The elongation value data reading unit 20 determines whether or not bending attribute information having an elongation value information condition that matches the bending condition Ki input by the operator exists in the database 15 of the master device 11, and if so, determines that. The elongation value data (predicted elongation value data or site-side elongation value data) is read, and the elongation value is set in the surface combining unit 22. If the bending attribute information having the elongation value information condition that matches the bending condition Ki does not exist in the database 15, the finite element method unit 21 is activated to set the bending condition Ki.
[0042]
The finite element method unit 21 automatically obtains an initial stroke amount (initial D value) based on the bending condition Ki, and displaces the work using the finite element method while lowering the initial stroke value until the punch reaches the initial D value. .
[0043]
Then, it is determined whether or not the displacement angle of the workpiece after the occurrence of the springback when the punch is released after reaching the target D value (after the unloading) coincides with the target angle (bending angle). If the angles do not match, a new target D value is automatically calculated, and the work is again shifted by the finite element method using the new target D value. That is, the elongation value is geometrically obtained from the input condition. Then, the obtained predicted elongation value is set in the surface combining unit 22, and the master unit 11 is caused to transfer the predicted elongation value and the related information at the time of obtaining the elongation value to the master unit 11 as predicted bending attribute information.
[0044]
The plane synthesizing unit 22 performs a process of matching a reference plane on the screen with a matching plane. In this matching process, both surfaces are compared in an overlapping region having a plate thickness and an elongation value, and the combined surface diagram is displayed on a screen.
[0045]
The three-dimensional plotting unit 23 defines a surface model (three-dimensional diagram data) obtained by defining the two-dimensional surface composite diagram obtained by the surface compositing unit 22 in three-dimensional coordinates and bending it under the bending condition Ki, and then adding a plate thickness. ) Is generated, and a three-dimensional figure obtained by rendering the three-dimensional figure data is displayed on a screen. A bending attribute is added to a corner portion of the three-dimensional view data. In addition, the three-dimensional drawing unit 23 sends the three-dimensional drawing data to the parent device 11 in response to the input of the transfer instruction.
[0046]
The graphic editing unit 25 performs an interference check on each of the three-dimensional surfaces of the three-dimensional drawing data, and displays the interference locations in different colors. Then, the area of the plane composite diagram from which the interfering three-dimensional plane is generated according to the operator's instruction is deleted from the plane composite diagram.
[0047]
Further, the figure editing unit 25 opens the three-dimensional view in the reverse order of the actual processing (starting from the last bending and finally opening the whole), and checks whether or not the mold interferes. Then, a process of separating the surface composite diagram is performed according to an instruction of the operator.
[0048]
When being notified that the graphic editing has been completed, the developed view generating unit 24 performs a single-stroke operation on the surface composite view, and passes the obtained closed loop to the CAM 26 as final developed view data (including bending lines). The development view data is transmitted to the base unit 11 in accordance with the input of the transfer instruction.
[0049]
The CAM 26 generates a machining program such as a mold setup and a machining trajectory on the workpiece based on the development data, and causes the master machine 11 to register the machining program.
[0050]
The base unit 11 has a function of transmitting data to the automatic programming device 10, the NC device 12, and the terminal 13 by using a predetermined network OS (for example, windowsNT). In addition, the base unit 11 includes a bending attribute information collecting unit 30 and a graphic data collecting unit 31 as shown in FIG.
[0051]
The bending attribute collection unit 30 collects the predicted bending attribute information from the automatic programming device 10 or the bending attribute information on the site side from the NC device 12 in the file 15.
[0052]
Further, the graphic data collection unit 31 of the master unit 11 registers the developed view data and the three-dimensional view data from the automatic programming device 10 in a hierarchical structure based on the part number, and transmits the developed view data and the three-dimensional view data to the NC device side. Forward. Master device 11 also stores a processing schedule and the like.
[0053]
The NC device 12 causes the processing schedule, the developed view data of the product, and the three-dimensional view data to be transferred, and displays the developed view based on the developed view data and the three-dimensional view based on the three-dimensional view data (the dimensions are also displayed) on the screen. After determining the L value and the D value (determining the bending order and the mold), actual processing is performed while performing simulation .
[0054]
In addition, the worker inputs bending attribute information when the L value is determined, and transfers the bending attribute information to the base unit 11 with a machine number (bender) added in accordance with the input of the storage instruction. That is, to transfer the bending attribute information consisting of the elongation value information condition and elongation value data and machine number shown in FIG. 2 to the base unit.
[0055]
The operation of the sheet metal integration support system configured as described above will be described below. FIG. 4 is a schematic flowchart illustrating the operation of the sheet metal integration support system according to the present embodiment.
[0056]
Operator site side of the NC apparatus 12 to the beginning, developed view data from the base unit 11, to transfer stereographic data, as shown this development diagram data and development diagram based on the stereographic data, the solid view in Fig. 5 After the confirmation, both images are confirmed. After the confirmation, the bending order, the mold and the like are determined, the L value and the D value are calculated, and the actual processing is performed while performing the bending simulation . Then, the dimensions, bending angles, and the like of the obtained product are confirmed by collation with the three-dimensional view of the screen. The bending angle, bending R, and the like can be confirmed by enlarging the corner portion of the three-dimensional view as shown in FIG.
[0057]
Next, when the dimensions of the three-dimensional figure are different, the elongation value is obtained by back calculation from the L value, and this elongation value is transferred to the base unit 11 (S401).
[0058]
This transfer is performed by inputting a storage instruction, and is transferred to the master unit 11 as bending attribute information on the site side including the material name, machine number, bending angle, etc. in addition to the elongation value as shown in FIG.
[0059]
Further, the elongation value of the above actually actually measured After allowing bending by using a test e e scan, the difference between the dimensions of the measured value and the solid view, the difference predictive elongation value of the expected elongation value In some cases.
[0060]
Next, master device 11 collects bending attribute information Ci on the site side in database 15 (S402). FIG. 4 shows that predicted bending attribute information Bi with an elongation value of “1.0” and bending attribute information Ci on the site side with an elongation value of “1.5” are collected.
[0061]
In the state where the bending attribute information Ci on the site side is collected in the master unit 11 in this way, each surface information constituting a solid based on the three-view drawing is defined in the automatic programming device 10 by the operator on the office side. Then, the automatic programming device 10 performs the processing described below.
[0062]
The automatic programming device 10 displays these surfaces on the screen by the CAD function, and when two joining sides are designated in the surfaces, performs a surface synthesizing process (S403). In this plane synthesis processing, a plane having a joint side designated first is set as a reference plane, and a plane having a joint side that is later is set as a mating plane. Then, a plane composite diagram having an overlapping area of the elongation values of the bending attribute information on the site collected by the master unit 11 is generated and displayed.
[0063]
When there is no bending attribute information that matches the bending condition Ki, the elongation value by the finite element method is used.
[0064]
Next, the automatic programming device 10 generates a three-dimensional figure from the plane composite figure obtained in step S403 in accordance with the input bending condition Ki, and displays the three-dimensional figure as shown in, for example, FIG. 5 (S404). ).
[0065]
In generating the three-dimensional figure , a surface model (three-dimensional figure data) is generated by defining a two-dimensional surface composite figure in three-dimensional coordinates, bending the sheet under bending conditions Ki, and adding a sheet thickness. A three-dimensional figure rendered on the three-dimensional figure data is displayed on the screen.
[0066]
Also, an interference check (interference between surfaces, interference between a three-dimensional surface and a mold, interference between three-dimensional surfaces) is performed on each three-dimensional surface of the three-dimensional diagram data, and a shape editing process for displaying the interference portion in different colors is performed ( S405). In this shape editing processing, the overlapping area of the plane composite diagram from which the interfering three-dimensional surface is generated according to the operator's instruction is deleted from the plane composite diagram. Then, the three-dimensional view data is finally transferred to the master unit 11.
[0067]
Further, obtains the size of the solid figure from the cursor direction in solid view, performs size display processing for processing overlapping the dimensions solid view (S406).
[0068]
Further, the three-dimensional view is opened in the reverse order of the actual processing (starting from the last bending and finally being fully opened), and it is checked whether or not the mold interferes. Then, an inverse simulation process for separating the surface composite diagram is performed according to the instruction of the operator (S407). Next, a single-stroke operation is performed on the surface composite diagram, and a developed diagram generation process of passing the obtained closed loop to the CAM 26 as final developed diagram data (including a bending line) is performed (S408). This developed view data is sent to the master unit 11.
[0069]
That is, the base unit 11 semi-automatically stores the elongation value of the site corresponding to the state of the machine on the user side by feedback, and uses this accumulated data to create graphic data by an automatic programming device. Bending is done using.
[0070]
Therefore, in the automatic programming device, each time the graphic data is used on the NC device side, the bending attribute information based on the elongation value on the site side instead of the predicted elongation value is accumulated, so that a more accurate development view can be obtained. I will get it.
[0071]
In each embodiment, the host device is constituted by the master unit and the automatic programming device. However, the functions of the master unit and the automatic programming device may be realized by one personal computer.
[0072]
Further, although the example has been described in which the NC device and the LAN are directly connected, the present invention may be applied to a system connected to the NC device via a local slave unit.
[0073]
【The invention's effect】
As described above, according to the present invention, the host device accumulates the bending attribute information on the site side from the lower device side in association with the machine number, and uses the bending attribute information on the site side to develop a development view and a three-dimensional view. Is generated and sent to the lower-level device, and the lower-level device displays the three-dimensional view and the expanded view from the higher-level device in conjunction with each other. Then, the worker on the site side transfers the elongation value obtained on the site side to the parent machine.
[0074]
That is, there is an effect that the host device can obtain an accurate development view and a three-dimensional view in consideration of the elongation value according to the conditions of the machine and the mold on the site.
[0075]
Also, on the site side, the host device sends accurate graphic data created using the accumulated elongation value data, so on the site side there is less input work on processing information required for bending, so the number of work steps is reduced. This has the effect of reducing input errors and eliminating input errors.
[0076]
Further, since the lower-level device is integrated in the upper-level device every time the expansion value is corrected, the latest expansion value is always accumulated.
