[0001]
BACKGROUND OF THE INVENTION
The present invention is a sheet metal integration support having a bending result transfer function for transferring the actual bending information of a bending machine when a workpiece is bent based on a development view of a product from the host device to the host device and collecting it in the host device. It relates to the NC device of the system.
[0002]
[Prior art]
In recent years, line control systems for machine tools (bending, laser, punching, etc.) have advanced. In such a line control system, as shown in FIG. 15, an automatic programming device 1 (CAE) having a CAD / CAM function and a parent device 2 as a server are arranged on the office side, and these higher-level devices and lower-level devices are arranged. An on-site machine tool (NCT / laser, vendor), which is a device, is connected 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 imagining a three-dimensional shape based on a three-view drawing, and then generates the CAD with the CAM function. Appropriate tools were assigned to the developed drawings, laser trajectories were obtained, and these machining programs were transmitted to the main unit 2.
[0004]
In generating the development chart, the operator on the office side uses the elongation values described in the elongation value table. This elongation value table describes a plurality of elongation values determined by vendor characteristics, bending conditions, and the like.
[0005]
However, the developed view generated using such an elongation value is an NCT / laser processing program, and thus is not transmitted to the vendor side despite the fact that an online system is built.
[0006]
Also, the reason why this development view is not sent to the vendor side is that the bending elongation value cannot be determined unless the vendor's unique characteristics are fully understood.
[0007]
For this reason, a bending instruction and a three-sided drawing were handed to the field side worker, and the field side worker compared the bending instruction, the blank material after NCT processing, and the three-sided drawing, The bending line is drawn on the blank material in consideration of the typical elongation value, and the bending order, bending mold, bending angle, stroke, etc. are determined. These decisions were made while the workers on the site side imagined the three-dimensional shape from the three views.
[0008]
And the worker on the site side calculated the L value and D value on the vendor side from the above-mentioned determination items and input them to the NC device 5. In determining this L value, the L value was entered in consideration of the elongation value based on the dimensions of the three views passed.
[0009]
[Problems to be solved by the invention]
However, in the conventional bending method, the vendor side worker only determines the bending elongation value empirically from the three views, and determines the L value, the D value, etc. based on this elongation value to perform the bending. . In other words, despite the fact that an online system has been established, the actual bending information measured on the vendor's site has not been transferred online, so the actual bending information cannot be collected on the site. was there.
[0010]
For this reason, the operator on the office side basically has to generate a development view based on the elongation value determined based on the elongation value table provided on the office side. It was not possible to obtain an accurate development considering the elongation value according to the situation.
[0011]
The present invention has been made to solve the above problems, and is a sheet metal integrated support system that transfers bending information on bending products determined by a worker on the field side of a bending machine every time the bending products are obtained.

[0035]
The configuration of the NC device 12 will be described in more detail with reference to FIG. As shown in FIG. 2, it is connected to the bender side shaft section 25 and sends out a control signal for controlling each shaft motor (not shown).
[0036]

[0040]
On the other hand, the NC device 12 includes a bending preparation data generation unit 16, a bending machine control value calculation unit 17, a processing command unit 18, a bending information correction unit 19, a measurement value reading unit 20, a correction value calculation unit, a bending information table 22, In addition to the transfer data generation unit 23, a data transmission / reception processing unit 30, a production graphic information display command unit 32, an image display processing unit 33, an input control unit 36 (connected to the touch panel 35), and the like are provided.
[0041]
The data transmission / reception processing unit 30 manages communication with the base unit 11, and stores the retained mold information, machine information, processing schedule, production part development view data Ai, 3D view data Bi, and the like from the base unit 11 in the database 31. Or the actual bending control value information and the actual bending control value correction information from the transfer data generation unit 23 are transmitted to the master unit 11.
[0042]
The image display processing unit 33 generates a processing screen for each unit and displays it on the screen 38. For example, a development view and a three-dimensional figure based on this three-dimensional figure are displayed simultaneously, or an event of the input control unit 36 is decoded and sent to each part.
[0043]
The production graphic information display command unit 32 displays the processing schedule of the database 31 on the screen, and when the part information of the processing schedule is selected, the related information of the part information is displayed via the image processing unit 33. For example, a development view Ai and a three-dimensional figure Ci of the selected part are displayed on the screen.
[0044]
The operation of the NC apparatus of the sheet metal integration support system having the bending result information transfer function configured as described above will be described below with reference to the flowcharts of FIGS. 3 and 4.
[0045]
The vendor-side worker turns on the NC device 12 to activate the system (S301). Next, the NC device 12 acquires various information related to the machine and the holding mold from the parent machine 11 using the data transmission / reception processing unit 30 (S302). Various information regarding the machine and the holding mold is associated with the machine (vendor) ID and stored in the database 15 by the parent machine 11, and the data transmission / reception processing unit 30 is in a format with the machine ID at the head. It communicates with the base unit 11 to obtain the various information described above.
[0046]
Next, the NC device 12 acquires a machining schedule and data related to the machining schedule from the parent machine 11 (S303). For example, a material, a development view, a three-dimensional view, a machine name, and the like are acquired. These data are stored in the database 31 of the NC device 12.
[0047]
Next, the production graphic information display command unit 32 displays all the machining schedules transferred from the master unit 11 on the screen 38 via the image processing unit 33, and selects a machining product with any machining schedule (S304). .
[0048]
Next, the production graphic information display command unit 32 causes the data transmission / reception processing unit 30 to transfer data related to the selected processed product (S305). For example, the bending order of the processed product, the mold used, bending control value information (L value, D value, Y value, Z value), etc. are transferred. This bending actual control value information is bending NC data and is transferred by the NC device 12.
[0049]
Next, the production graphic information display command unit 32 determines whether or not data related to the processed product in step S305 has been transferred (S306).
[0050]
In step S306, when the data regarding the processed product is not transferred, it is determined that the processed product is a new process, and the development view Ai and the three-dimensional view Ci of the processed product are displayed in conjunction with each other on the screen 38 (S307). The three-dimensional figure Ci is obtained by the image processing unit 33 projecting the three-dimensional data (surface model) from the master unit 11 onto a two-dimensional space and performing a hidden surface process.
[0051]
Next, the bending preparation data generation unit 16 displays a development view Ai as shown in FIG. Then, as shown in FIG. 4, the bend line in the developed view is picked up and the mold to be used is automatically obtained, and the layout of the mold is performed (S401). Along with the processing in step S401, the bending preparation data generation unit 16 allocates the part information data (part number, development view, and three-dimensional view in FIG. 7) registered in the database 31, and uses this development view data. The bend information data Hi corresponding to the bend line number, bend sequence, mold number, material, etc. is generated in the memory 22 in association with each other.
[0052]
The bending information data Hi on the site side is associated with the bending line number, bending order number, and bending conditions (material, bending angle, bending direction, mold, etc.) designated by the site side worker. The actual NC data area 40 in which the control value information (L value, D value, Y value, Z value) is written, the correction value data area 41, and the like are made to correspond to each other.
[0053]
Next, as the bending information data on the site side is generated, the bending machine control value calculation unit 17 allocates the bending line information, bending conditions, and the like of the development diagram related to the data, and the bending line Bending control value information (L value, D value, Y value, Z value) is obtained and stored in the NC data area 40 as shown in FIG. 8 (S402).
[0054]
For example, if the vendor has the structure of the shaft portion 25 shown in FIG. 2, the control value of the Y1 axis, the control value of the L1 axis, the control value of the Z1 axis, the control value of the Y2 axis, and L2 The control value of the axis and the control value of the Z2 axis are obtained.
[0055]
Next, the bending machine control value calculation unit 17 determines whether or not the bending control values for all the bending lines displayed on the screen have been obtained (S403), and if not, the process returns to step S401 to continue. The bending control value information (L value, D value, Y value, Z value) is obtained by designating the bending line.
[0056]
Further, in step S403, the bending control value information of all the bending lines of the developed view displayed on the screen (L1 value, D1 value, Y1 value, Z1 value, L2 value, D2 value, Y2 value, Z2 value,...) 9 is displayed using the image processing unit 33 as shown in FIG.
[0057]
Then, the worker presses a machining start button (not shown) provided in the NC device 12 (S404). As the machining start button is pressed, the bending machine control value calculation unit 17 performs actual bending control value information (Y1 axis control value, L1 axis control value, Z1 axis control value, Y2 axis control) for each bend line. Value, L2-axis control value, Z2-axis control value) are read from the bending information data Hi of the memory 32 and set in the machining command unit 18 to control each axis of the bender.
[0058]
The machining command unit 18 drives each axis to be positioned so as to obtain each control value set while constantly reading the control result of each axis (S405).
[0059]
Next, the worker measures the size, angle, etc. of the bent workpiece using a digital caliper and an angle measuring device (not shown) (S406).
[0060]
This measurement result (actual control value information on the machine side; Lp value, Dp value, Yp value, Zp value) is read by the measurement value reading unit 20 and sent to the correction value calculation unit 21 as shown in FIG. Display. In FIG. 9, the L value, the D value, the Y value, and the Z value are simply displayed.
[0061]
The worker determines whether or not the workpiece has been bent as planned with reference to the actually measured workpiece dimensions and angles, the developed view, and the three-dimensional view (S407).
[0062]
If it is determined in step S407 that the worker is not bent to the expected size (dimension based on the three-view drawing) and the planned angle (angle based on the three-view drawing), the worker is displayed on the screen. (Y1 axis, L1 axis, Z1 axis, Y2 axis, L2 axis, Z2 axis), and operate the digital pulser handle 45 to measure Y1 axis, L1 axis, Z1 axis, Y2 axis in units of several microns. Each control value (NC data of bending) of the L2 axis and the Z2 axis is corrected (S408).
[0063]
The correction value by the digital pulser is input to the bending information correction unit 19 and is used as a control value (Y1 axis, L1 axis, Z1 axis, Y2 axis, L2 axis or Z2 axis) of each axis set in the machining command unit 18. Then, the value by the digital pulser is added or subtracted (S409).
[0064]
Next, the machining command unit 18 performs the positioning operation of each axis with the corrected bending control value information (LM value, DM value, YM value, ZM value), and the process returns to step S406 to be bent again. The dimensions and angles of the workpiece are measured (S410).
[0065]
If it is determined in step S407 that the worker, who is a bending machine, has the dimensions as planned and has been bent at a predetermined angle, the operator presses a set button indicating successful processing (S411).
[0066]
As the set button is pressed, the measured value reading unit 20 shows the actual control values (Y1p axis, L1p axis, Z1p axis, Y2p axis, L2p axis, or Z2p axis) on the machine side of each axis as shown in FIG. Are stored in the bending information table of the memory 32 in correspondence with the bending line numbers.
[0067]
Next, the correction value calculation unit 21 determines the actual control value of the bending line on the machine side of the bending information table (for example, Y1p axis, L1p axis, Z1p axis, Y2p axis, L2p axis, or Z2p axis) when the set button is pressed. ) And bending control value information (L value, D value, Y value, Z value), and these difference data (for example, L1α value, D1β value, Y1α value, Z1α value, L2α value, D2β value, Y2α value, Z2α) is obtained as a correction value for each axis, and these difference data (correction data) are related and stored in the bending information data area 42 as shown in FIG. 11 (S412).
[0068]
That is, after obtaining the predicted control value on the vendor side from the development view, correcting the predicted control value based on the experience value of the worker and controlling the bending machine, the actual control value and the predicted control value on the bending machine side Therefore, the difference data of the Lα value, the Yα value, and the Zα value is correction data including the characteristics of the bending machine and the experience of the operator.
[0069]
Next, it is determined whether difference data has been obtained for all bend lines (S413).
[0070]
If it is determined in step S413 that difference data for all bend lines has not been obtained, the process returns to step S403 to perform axis positioning based on the next bend line and obtain difference data.
[0071]
If it is determined in step S413 that difference data for all bend lines has been obtained, the worker presses the work end button (S414). Along with this pressing, the transfer data generation unit 23 reads the actual bending information data Hi on the field side related to the part number of the bending information table 22 and the difference data (developed actual control value correction information) of the development view, and adds the machine number. Then, transfer data in the format is generated, and this transfer data is set in the data transmission / reception processing unit 30 and transferred. That is, the data transmission / reception processing unit 30 transfers the transfer data shown in FIG.
[0072]
On the other hand, the base unit 11 receives the transfer data from the NC device and collects it in the database 15 as shown below.
[0073]
The master unit 11 receives, for example, part information data (part number, part information, material name, comment, data, development view, machine name (vendor or NCT), NC data of NCT, processing setup, etc.) from the automatic programming device 10. When transmitted, as shown in FIG. 13, the part information and file data which are CAD data are registered under the part number. This file data is composed of development view data and stereoscopic view data.
[0074]
Also, NCT NC data, machining setup, etc., which are CAM data, are registered under the part number, and bend CAM data is added to the CAM data. The bend CAM data indicates the ID of the bend CAM data (L, D, Y, Z from the NC device 12) by the program number and the machine name. That is, this ID determines the type of machining of the machine. Also, bending NC data (L, D, Y, Z) is stored under this ID.
[0075]
The master unit 11 includes a bending elongation information file (not shown). As shown in FIG. 14, the bending elongation information file is managed by a bending elongation ID, and includes a bending condition portion and an elongation value data portion under the bending elongation ID. A machine number is added below the elongation value data portion.
[0076]
The bending condition part is composed of a bending elongation ID, a material name and an angle, a calculation / manual input flag for indicating a predicted attribute or bending attribute information based on an actual value from the site side. The elongation value data portion is composed of an elongation value, a bending load, a springback amount, and the like. This elongation value is obtained by setting the difference data of the LM value transferred from the site side when the worker actually bends the workpiece to obtain the product of the part number (bending depending on the bending condition) as the elongation value. .
[0077]
In other words, it indicates whether the elongation value, springback amount, stroke amount (amount based on the difference in the transferred D value), etc. for each bending condition is based on the prediction by the automatic programming device or the results from the field side, and which machine (Vendor) indicates whether the data is registered.
[0078]
For this reason, when the automatic programming device 10 generates a development view with the same bending conditions as those registered in the bending information file, the bending information file actually includes the bending conditions in the past under the bending conditions. Since the actual elongation value and the like when it is bent under the conditions are registered, it is possible to generate a development view and a three-dimensional view with the actual elongation value, so both the development view and the three-dimensional view are accurate.
[0079]
That is, the extension value on the site side according to the state of the machine on the user side is semi-automatically accumulated in the master unit 11 by feedback. Using this accumulated data, graphic data is created by an automatic programming device, and this graphic data is created on the site side. It is possible to bend using the.
[0080]
Therefore, in the automatic programming device, every time graphic data is used on the NC device side, the elongation value on the site side is accumulated.
[0081]
In the above embodiment, the difference data (Lα value) between the control value (L, D, Y, Z) and the measured actual control value information Lp value, Dp value, Yp value, Zp value on the machine side. , Dβ value, Yα value, Zα value), and the difference data and control values are transferred, but the actual control values (LM, DM, YM, ZM) on the bending machine side and the measured actual values on the machine side Difference value (Lα value, Dβ value, Yα value, Zα value) of the control value information Lp value, Dp value, Yp value, and Zp value of the difference value and the actual control values (LM, DM, YM, ZM), etc. may be transferred.
[0082]
As described above, when the actual control values (LM, DM, YM, ZM) are transferred, when the same product is bent, the LM, DM, YM, ZM is transferred to the NC device as NC data to the NC device 12. Since the NC data sent is the LM, DM, YM, ZM on the site side when the part is bent, the field worker can trust the NC data of the transferred bending to be the control value of the vendor. it can.
[0083]
  As described above, according to the NC apparatus of the sheet metal integration support system having the bending performance transfer function of the present invention,Based on the experience of the workers on the job site and the actual machine characteristics, the front side of the abutment device (X axis: L axis direction), the horizontal direction (Y axis), the vertical movement direction (Z axis), and the bending machine There is an effect that correction data of control values of each axis in the pressing direction (Z axis: D axis) can be stored in the host device in association with the machine number.
[0086]
  The sheet metal integration support system of the present invention isOn the host device side, there is an effect that it is possible to obtain an accurate development view and a three-dimensional view based on the elongation value of the bending condition based on the mechanical characteristics on the site side and the experience of the worker.
[0090]
In addition, since accurate graphic data created using the extension value accumulated by the host device is sent on the site side, the number of operations required for bending is reduced on the site side, reducing the work man-hours. In addition, the effect of eliminating input mistakes is obtained.
