Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mold management method and apparatus in an automatic programming apparatus for a punch press.
[0002]
[Prior art]
Conventionally, in an automatic programming device for punch presses (hereinafter referred to as “automatic pro” in this specification), information on a mold to be used is registered in a nonvolatile memory in advance, and an NC program is created while referring to the mold information. Etc. are performed.
[0003]
The conventional mold management method in automatic professionals consists of a method of managing only the molds mounted on the lower turret above the turret punch press, and possession consisting of a mold mounted on the turret and a spare mold. There are two ways to manage the mold.
[0004]
Further, items to be considered regarding the mold during the operation of the automatic professional are the selection of the mold, mold information, the number of molds, the turret mounting angle, and the turret mounting position.
[0005]
“Selection of mold” means that a mold used at the time of mold allocation is selected by mold management.
“Mold information” refers to information relating to the shape of the mold, such as shape and size.
“Number of molds” refers to information on whether or not a plurality of molds having the same shape in the vertical and horizontal directions can be used at the same time. In other words, the number of molds is the same shape but the mounting angle at the turret is This is information on whether or not these identically shaped molds can be used in different cases.
[0006]
The “turret mounting angle” is information on the angle at which the mold is mounted on the turret.
The “turret mounting position” is information on a turret station number on which a mold is mounted.
[0007]
[Problems to be solved by the invention]
By the way, the conventional mold management method in an automatic professional has the following problems.
[0008]
In the method of managing only the molds mounted on the turret, problems are shown for each item as follows.
[0009]
In “Selection of mold”, it is possible to select only the mold set in the turret mold arrangement, and therefore, if there is no corresponding mold, it must be newly set. Usually, since the number of held molds is larger than the number of turret stations, there is a problem that the setting and erasing of the molds must be repeated for the turret mold arrangement.
[0010]
In the “Mold Information”, due to the problems in the above “Mold Selection” item, each mold information must be set correctly each time the mold is set in the turret mold arrangement. There was a problem of not becoming.
[0011]
In the “number of molds”, although two molds can be used vertically and horizontally like a long angle mold or a long round mold, only one is set for the turret mold arrangement. There is a problem that it is not used because it is not used, or two vertical and horizontal ones are actually used even though only one can be used.
[0012]
In the “turret mounting angle”, only the angle set in the turret mold arrangement is used, so even if the mold has the same shape, it is determined that there is no mold if the set angle is different. For this reason, there is a problem that it is necessary to change the setting contents when the angles are different.
[0013]
In the “turret mounting position”, there is a problem that when there is no mold at the turret station number location registered in the turret mold arrangement, it is necessary to automatically embed the mold in the turret.
[0014]
In the method of managing the holding mold, the problems for each item are as follows.
[0015]
In “selection of molds”, there is a problem that when managing molds owned by a plurality of machines, even molds that cannot be used by the machines are selected.
[0016]
In the “mold information”, when managing the molds owned by a plurality of machines, there is a problem that even if the molds have the same shape, the set contents differ depending on the machines used.
[0017]
In the “number of molds”, there is a problem that it is impossible to determine how many machines can be used when managing molds owned by a plurality of machines.
[0018]
In the “turret mounting angle”, since the turret mounting angle of the mold is positioned by the key and the key groove, the positions of the key and the key groove may be different depending on the machine when managing the holding mold of a plurality of machines. Therefore, there is a problem that the angle at which the mold can be mounted differs depending on the machine.
[0019]
In the “turret mounting position”, when managing the dies of a plurality of machines, there is a problem that the turret station number to be mounted is different for each machine.
[0020]
From the above, in the conventional automatic professional, only a part of the mold to be used can be managed by the management method of only the mold attached to the turret. I can't. Also, there is a problem that the mold setting and erasing operations must be repeated, the mold information must be set each time, and the turret station number and angle to be mounted must be determined each time. .
[0021]
In addition, the conventional method for managing held molds has a problem that machine-specific information such as mold information, mounting position, and mounting angle is insufficient.
[0022]
SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an automatic programming for a punch press that can efficiently manage molds held by a plurality of machines by an automatic professional while looking at the whole. An object of the present invention is to provide a mold management method and apparatus therefor.
[0023]
[Means for Solving the Problems]
In order to achieve the above object, a die management method in an automatic programming device for a punch press according to the present invention according to claim 1 is a method for setting a die placement management method for each of a plurality of machines. Information that is limited to the molds that can be used for each machine is set as a machine-owned mold information file, and the turret information in which this machine-owned mold information file and information on the mold station of the machine are set By performing an automatic programming operation with reference to a file, a station determination process for all dies to be used for machining is performed based on the machining program.
[0024]
Therefore, in the automatic professional, the machine-owned mold information file and the turret information file are managed only in the range of the possessed mold used only for each machine in the machine-owned mold information file and the turret information file. Since automatic programming work is performed based on the machining program while referring to the file, the turret station number on which the mold is to be mounted is automatically determined by the turret station determination process, and NC data is created.
[0025]
As a result, it takes less time to select the mold, and the automatic professional work is performed efficiently. It also contributes to reducing errors in the NC program such as the mold mounting turret station number, mounting angle, start / cancel command, and the number of molds of the same shape used.
[0026]
According to a second aspect of the present invention, there is provided a die management apparatus for use in an automatic programming device for punch presses according to the present invention. Machine-owned mold management file that stores mold management information, and machine-owned mold information that stores information limited to the molds that can be used for the machine in the machine-owned mold management file for each machine A file and a turret information file in which information on the mold station of the machine is set up are used for machining based on a machining program to perform automatic programming work with reference to the machine-held mold information file and the turret information file. The present invention is characterized in that a station determination processing unit for performing station determination processing for all molds to be performed is provided.
[0027]
Therefore, the operation is the same as that of the first aspect, and in the automatic professional, the machine-owned mold information file and the turret information file are managed in a limited range of the owned molds used only for each machine. Since the automatic programming work is performed based on the machining program while referring to the machine-owned mold information file and the turret information file, the turret station number for automatically mounting the mold is determined by the turret station determination process, NC data is created.
[0028]
As a result, it takes less time to select the mold, and the automatic professional work is performed efficiently. It also contributes to reducing errors in the NC program such as the mold mounting turret station number, mounting angle, start / cancel command, and the number of molds of the same shape used.
[0029]
DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a mold management method and apparatus in an automatic programming apparatus for a punch press according to the present invention will be described below with reference to the drawings, taking an automatic professional for a turret punch press as an example.
[0030]
Referring to FIG. 3, a plurality of, for example, three turret punch presses 1A, 1B, 1C are installed in the present embodiment. Each turret punch press 1A, 1B, 1C has a general structure having an upper turret 3, a lower turret 3, a carriage base 7, a carriage 9, a work clamper 11, a center table 13, and a side table 15. That is, a plurality of molds 17 (punch P, die D) are detachably mounted on the lower turrets 3 and 5 while being rotatable and indexable. Moreover, the carriage 9 provided on the carriage base 7 that can move in the front-rear direction (left-right direction in FIG. 3) is movable in the left-right direction (longitudinal direction of the plate material storage shelf, up-down direction in FIG. 3).
[0031]
Therefore, the plate material W gripped by the work clamper 11 mounted on the carriage 9 is positioned in the punching position by being positioned in the front-rear and left-right directions, and the upper and lower turrets 3 and 5 are rotated and positioned. The punch P that has been ejected is hit downward and punching is performed.
[0032]
The three turret punch presses 1A, 1B, and 1C are arranged such that the desired mold 17 is placed on the upper and lower turrets of the turret punch presses 1A, 1B, and 1C by a mold changer (not shown) from the mold storage device 19. 3 or 5, or the molds 17 of the upper and lower turrets 3 and 5 are accommodated in the mold storage device 19.
[0033]
The three turret punch presses 1A, 1B, and 1C are electrically connected to an automatic programming device 21 (referred to as an automatic professional) serving as a control device.
[0034]
As shown in FIG. 4, the automatic professional 21 stores, for example, an input device 25 and a display device 27 for inputting data such as a machining program and a mold 17 to the CPU 23 as a central processing unit, and the input data. A memory 29 is connected.
[0035]
In the memory 29, a machining program file 31 is provided, and each of the three turret punch presses 1A, 1B, 1C (simply expressed as “machine” in the present embodiment) is a nonvolatile memory. Machine holding mold management files 33A, 33B, and 33C are provided, and in each of these machine holding mold management files 33A, 33B, and 33C, the mold 17 used for each machine is shown in FIGS. As shown in FIG. 4, a machine-owned mold information file 35 and a turret information file 37 are provided.
[0036]
More specifically, the machine-owned mold information file 35 stores all the molds 17 used in the corresponding machine as information as shown in FIG. For example, even if there is only one mold 17, it is listed if it can be used with the machine. If the machine can be used on another machine but cannot be used on the machine, it is not listed in the machine possession mold information file 35 of the machine. That is, only the holding mold information that can be used by each machine is listed. Even if the mold 17 has the same shape, two pieces of data can be used because the two mounting angles can be used as in the case of 0 ° and 90 °, for example.
[0037]
More specifically, the machine-owned mold information file 35 stores information limited to the mold 17 that can be used for each machine. As shown in FIG. The mold information 39, the mounting turret station information 41, the mounting angle information 43, and the number of molds 45 are stored.
[0038]
The above-described mold information 39 includes mold shape information related to the mold shape such as shape, size, direction, and name, and is output before and after a certain mold 17 is used in the machine. Contains start / cancel commands that must be done. Examples of the start / cancel command include M codes such as air blow ON / OFF, molding die up / down ON, stroke pattern selection, and press pattern command.
[0039]
The mounting turret station information 41 includes, for example, information on a turret station as a mold station to be mounted when a certain mold 17 is used in the machine, such as fixed / designated station, external track designation, auto index. There is information such as designation and no designation.
[0040]
Note that the fixed / designated station is one in which the turret station number to be installed is fixed / designated. When fixed, the turret station number is always installed at the fixed station, and when designated, it is installed at the designated station as much as possible.
[0041]
Further, the designation of the outer track means that the turret station number to which the mold 17 is mounted is not specified, but is mounted on the outer track. For example, in the case of the molding mold 17 or the like, the outer track designation is set. .
[0042]
Also, auto index designation is used as an auto index, and no designation means that the station number to be installed is not specified, and the turret station number that can be installed is used according to the state of the upper and lower turrets 3 and 5. It is what is done.
[0043]
The mounting angle information 43 is used to set an angle when a certain mold 17 is used in the machine, and includes information on angle designation and key information. The angle designation includes a mountable angle, and a plurality of angles can be set. Further, the key information includes information on the keys 17 and key grooves of the mold 17 and the upper and lower turrets 3 and 5 in advance, and an angle at which the key 17 can be mounted is calculated based on the keys and key grooves.
[0044]
As for the number of molds 45 described above, when the mold 17 having the same shape can be used as a plurality of molds 17, the mounting turret station information 41 and the mounting angles such as the vertical and horizontal directions are the same. May be different, and are stored separately in the machine-owned mold information file 35 as the number of pieces used. For example, in the case of a long-angle 100 × 10 mold 17, when two identical molds 17 are used, when the turret station number is T101 and the mounting angle is 0 °, the turret station number is not specified. In some cases, the mounting angle is 90 °.
[0045]
In more detail about the turret information file 37 described above, the turret information file 37 includes the T number and size of the turret station of the corresponding machine as shown in FIG. Key information such as key angle, index, and the like are set as machine-specific turret station information.
[0046]
The automatic program 21 performs automatic programming work with reference to the above-described machine-owned mold information file 35 and turret information file 37 based on the machining program. In this case, as shown in FIGS. 1 and 2, the station determination processing unit 47 finally determines the turret station number to which the machine-owned mold is mounted.
[0047]
Referring to FIG. 5, in the station determination processing unit 47, one of the three turret punch presses 1A, 1B, 1C is selected and the machining program file 31 is read (steps S1 and S2). ).
[0048]
All the mold codes in the machining program file 31 are compared with the data stored in the machine-owned mold information file 35 and the turret information file 37, and it is determined whether or not all the molds 17 are present. At this time, of the molds 17 in the turret information, those not used in the machining program may be empty stations (steps S3 and S4).
[0049]
If all the molds 17 are not present, the machine cannot be processed and the machine selection is performed again (step S5).
[0050]
If there are all molds 17, one of the mold codes is picked up, and it is determined whether or not the selected mold code is input to the turret information file 37 as previous information. (Steps S6 and S7).
[0051]
If the die code is input as the previous information in the turret information file 37 (YES) in the above step S7, the upper turrets 3 and 5 of the upper and lower turrets 3 and 5 are set at the die angle specified in the machining program. It is determined whether there is a key (step S8).
[0052]
If it is determined in the above step S8 that the upper turret 3 and 5 keys are present on the mold angle of the machining program (YES), it is determined whether the mold angle of the mold code matches the current situation. When it is determined that the mold angle does not match the current state (NO), the operator changes the mounting angle of the mold 17 and sets the T code (steps S9, S10, and S11).
[0053]
If it is determined in step S9 that the mold angle of the mold code matches the current state (YES), the T code is set (steps S9 and S11).
[0054]
Next, only necessary ones are set in the M code, and it is determined whether or not the settings for all the mold codes in the machining program have been completed. If YES, the turret station determination process ends (steps S12 and S13).
[0055]
If it is determined in step S13 that the setting for all the mold codes in the machining program has not been completed, another one of the remaining mold codes in the above-described step S6 is again used. The mold code is picked up, and the process proceeds to steps after step S7 (from step S13 to step S6).
[0056]
If the mold code is not input as previous information in the turret information file 37 (NO) in step S7 described above, it is determined whether or not a turret station is specified (steps S7 and S14). .
[0057]
If it is determined in step S8 described above that there is no key for the upper turrets 3 and 5 (NO) in the mold angle of the machining program, it is determined whether or not a turret station is specified (steps S8 and S8). S14).
[0058]
If it is determined in step S14 that the turret station is specified (YES), it is determined whether the specified turret station is empty. If it is empty, the mold angle of the machining program is determined. It is determined whether there are keys for the upper and lower turrets 3 and 5. (Steps S15 and S16).
[0059]
If it is determined in step S16 that there are keys for the upper and lower turrets 3 and 5 at the mold angle of the machining program, the T code and, if necessary, the M code are set (steps S16 to S11, S12). What).
[0060]
If it is determined in step S14 that the turret station is not designated (NO), all mold codes are again held in step S6 described above as a hold to determine the mold code designated in the turret station first. One of the remaining mold codes is picked up, and the process proceeds to the steps after step S7 (from steps S14 and S17 to S6).
[0061]
If the designated turret station is not empty (NO) in the above step S15, it is determined whether any machine is used to come to this step. If YES, the corresponding machine for executing the machining program is determined. If it is NO, an already set T code is cleared and machine selection is performed again (from steps S15, S18, S19 and S20 to S1).
[0062]
If it is determined in step S16 that there is no upper turret 3 or 5 key in the machining program mold angle (NO), an error occurs through step S18 described above, or steps S19 and S20 are performed. Then, the machine selection is performed again (from steps S16, S18, S19 and S20 to S1).
[0063]
As described above, turret station determination processing is automatically performed for all mold codes. In the automatic professional 21, the machine-owned mold information file 35 and the turret information file 37 are managed only in the range of the held mold 17 used for each machine, and the machine-owned mold information file 35 and the turret information file are managed. Since the automatic programming operation is performed based on the machining program with reference to 37, the turret station number to which the mold 17 is mounted is automatically determined by the turret station determination process, and NC data is created.
[0064]
It is possible to output a start / cancel command set in the mold information 39 for each mold 17 in the NC data.
[0065]
Therefore, it takes less time to select the mold, and the automatic programming work is performed efficiently. Further, it contributes to reducing errors in the NC program such as the mounting turret station number of the mold 17, the mounting angle, the start / cancel command, and the number of the same-shaped molds 17 used.
[0066]
The present invention is not limited to the embodiment of the invention described above, and can be implemented in other modes by making appropriate changes. In this embodiment, the turret punch press has been described as an example of the punch press, but other punch presses may be used.
[0067]
Further, in the embodiment described above, it is limited to the machine-owned mold, but it is also possible to manage the mold in a narrower range or a wider range with the same idea without being limited to the machine-owned mold. . For example, even if it is the same machine, if the contents of the mold to be used differ depending on the processing material, plate thickness, and processed product, the machine holding mold may be divided and managed finely for each material / product. Is possible. That is, it is possible to prepare a plurality of holding molds for one machine and switch them according to the material, plate thickness / product.
[0068]
Further, when a plurality of machines having the same specifications are held and the respective machine holding molds are the same, the machine holding molds may be unified and managed.
[0069]
The present invention can also be applied to an automatic programming device for a turret punch press having an automatic die change function. In other words, the molds in the upper and lower turrets and the tool stocker (storage) molds can be managed by automatic professionals as machine-held molds, and NC data can be created while referring to them.
