Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a die management method for a punch press equipped with a die selection / exchange device and a die management device.

[0002]

2. Description of the Related Art Generally, there are various types of methods for managing a die in a punch press equipped with a die selective exchange device. For example, give each mold a unique mold number,
By managing the mold information (shape, size, etc.) of each mold corresponding to the mold number, managing each mold,
Also, information unique to each of the upper die (punch) and the lower die (die) (production time, number of times of use, etc.) and set die information including die clearances when the upper and lower dies are set. There are various other types, such as those that store the information and manage the die exchange based on the set die information.

[0003]

However, all of the above-mentioned conventional ones have a problem that no consideration is given to a mold that can be identified as being intended for use. That is, it is needless to say that the shape, size, etc. of the punch, die, manufacturing time, number of uses, re-polishing history, etc. need to be individually controlled for each die, but this is not enough. Is enough.

For example, if two identical molds are purchased, both must be identified as individuals, but since they are considered to be used for the same purpose, they can be identified as the intended purpose. In that sense, it is not necessary to distinguish between the two and they may be treated as the same mold. That is, the mold data managed by the processing data creation device can be treated as the same mold, while the mold data managed at the processing site is the mold specified by the processing data creation device. It is possible to assign either of the molds to the data.

Further, even if the molds are completely different,
For example, when both are used for cutting the outer circumference, they can be regarded as the same purpose intentionally because they are used for the same purpose (used for cutting the outer circumference), and in that sense, it is not necessary to distinguish between the two.

However, the conventional one punches a die,
In order to manage each die individually, and in the case of a set die in which a punch and a die are set, each set die is individually managed. Must be treated as separate molds (punch / die or set molds) and therefore
The user cannot use the information that realizes the possibility of freely using the mold according to the user's intention, and therefore, the user such as the mold identification memo that the user has used before. The original usage cannot be reflected in the die press die management.

What is more problematic than the above is that every time the user purchases a mold, various mold information about the mold attached to the mold supplied from the seller is used. Since it is registered as data in the mold management system on the part of the operator, it is necessary to perform a troublesome and complicated data input operation of mold information, and the attached mold information is definitely the mold information of the purchased mold. There is a problem that it is not possible to verify whether or not, that is, whether or not the mold supplied by the distributor completely matches the mold delivered to the user.

An object of the present invention is to eliminate the problems of the above-mentioned conventional ones, eliminating the need for inputting mold information when purchasing a mold, and moreover, the mold supplied by the seller and the user's hand. It is an object of the present invention to provide a die management method and device for a punch press capable of verifying whether or not the die arrived at is completely matched.

[0009]

4 to 6 show the concepts of the unique code 20 and the shared code 40. For example, the same mold (for example, punch P1) having the unique code “12345” and the shared code “Z9876” shown in FIG.
When the die (punch P2) shown in (b) is purchased, the unique code of this new die (punch P2) is, for example, "22".
Although the individual is identified as "222", it can be identified intentionally with the previous die (punch P1), and thus the same shared code "Z9876" is attached. That is, the shared code “Z9876” of the previous die (punch P1) is duplicated in a new die (punch P2).

Further, for example, a die (for example, die D1) having a unique code "23456" and a shared code "Z8765" shown in FIG. 5A, and a unique code "45678" shown in FIG. Even if the mold (die D2) having the code "Z7536" is completely different from each other, if both have the same purpose (for example, to cut the outer circumference), see FIGS. 5 (c) and 5 (d). As shown, the same shared code (for example, “S5555”) is attached to both. As a result, two molds (dies D1 and D2) that inherit the attribute of cutting the outer circumference are generated. in this way,
Since one die can have a plurality of usage intents such as nibbling, overtaking, outer peripheral cutting, notch, single shot, etc., it can have a plurality of shared cords corresponding to a plurality of usage intents.

Further, for example, in addition to the unique code shown in FIG. 6 (a), a die (punch P) having shared codes "1", "4" ... "i", and the unique code shown in FIG. 6 (b). In addition to the above, when combined with a die (die D) having shared codes “2”, “4” ... “J”, as shown in FIG. 6C, punches having shared code “4” ... “i” are punched. / Die combination P / D is constructed. Further, as for the combination of the punch and the die, various combinations as shown in FIG. 6D are possible depending on conditions such as die clearance with respect to the punch.

FIG. 7 shows a flow chart of the entire die management in the punch press machine system including the die management method of the punch press according to the present invention. The die introduction processing (step S10) in the die management device and the machining data. Data creation processing by the creating apparatus (step S20), setup of the mold / material by the NC apparatus (step S30), punch / die calculation processing immediately before die replacement during processing (step S40),
The calculated punch / die replacement process (step S50),
Punch / die usage count update processing (step S60),
Further, it is configured by the processing for determining the end of processing (step S70).

Of these, in the die introduction process S10 in the die management apparatus, the unique code 20 and the shared code 40 are input and stored, and the die information 30 and 50 corresponding thereto are also input and stored. . As for the input method, the unique code 20 of the die is a bar code reader, a two-dimensional code reader, R
F-ID reader or manually read and store,
Information (shared code: mold group management number, mold information) used by the processing data creation device (for example, automatic programming device 3) or machine (for example, punch press machine 1) is extracted and stored. As a result, the validity of the delivered mold can be confirmed. Further, the shared code 40 can be easily added / changed by the user, and when added, the intention can be stored.

Further, the data creation processing S20 in the processed data creation device is to create processed data with the shared code 40 and the mold information 50 corresponding thereto, and transfer the used mold information and setup information to the NC device. is there. The operation of the processing data creation device is divided into two parts (the first part and the second part), and while the CAM part and the processing intention data are created as before, the processing machine is installed immediately before the processing. The available mold information (mounted mold information) that is available is transferred to the processing data creation device via the NC device. Based on this mounting die information, the processing data creation device can reduce the setup,
In addition, information on the mold used so that processing can be performed as intended.
Data of setup information is created or recreated and transferred to the NC device.

Further, the setup process S30 of the die / material in the NC device is a setup process based on the die information / setup information used accompanying the processing data. Material setup is
Check and allocate the materials required for processing. In the case of die setup, if the attached die cannot be used for processing in order to comply with the processing intent, there is a need for mold replacement, when changing molds for mold life management, and for changing the setting of alternative molds ( This is done in case of changing the contents of alternative information of type usage intention). The setting of the alternative mold can be changed during processing, in addition to the pre-setting before processing. Especially, for the replacement of the life, it is possible to change the setting before the life or ignore the life.

Further, the punch / die calculation processing S40 immediately before the die exchange during machining is to select the punch / die combination to be used for machining in the die information and material information used accompanying the machining data. Mold group used for processing from material, processing intention, and used mold information (alternative information on intended use of mold)
Select the punch / die to be actually used for processing from the die group according to the contents of life alternative, clearance alternative, application alternative, and so on. Further, the molds can be selected in advance while the processing is being performed, and the machine can be notified in advance. Furthermore, when performing die replacement / maintenance during processing, it is possible to reselect according to the progress of processing, including the information notified in advance.

Further, in the punch / die use count updating process S60, the die information can be discarded after the end of processing or at the time of die setup when the life is judged by the use history management for each punch / die. In addition, when it is remanufactured by re-polishing, it is recorded in the maintenance record.

FIG. 8 shows a specific example of the mold introduction process S10 in the mold management device of FIG. 7, which is a unique code reading process (step S11), and a mold information reading process from a distributor (step S12). , And shared code / die information storage processing in the server (step S13). Here, regarding the mold information reading process from the selling source (step S12), in the case of a standard mold, a part of the information may depend on the server on the user side.

FIG. 9 shows an example of an apparatus that realizes such a mold introduction process. That is, the local network 81 provided in the die management system 80 of the machine / die vendor and the local network 91 provided in the die management system 90 on the user side are the gateways 82 and 9.
2 are connected via the Internet or the like. A mold information server (for distributor) 83 is connected to the local network 81 of the machine / mold distributor, while a mold information server (for user) 93 is connected to the local network 91 on the user side. Processing data creation device 94,
And the processing machine / die information operating device 95 is connected. Then, from the mold information server (for user) 93, mold information (fixed information, update information) 3 corresponding to the unique code.
0 is read and stored in the list of the unique code 20, and mold information (fixed information, update information) 50 corresponding to the shared code is read and stored in the list of the shared code 40. Further, the unique code reading device 96 connected to the processing machine / die information operating device 95 is
The unique code 20 is read from each die.

FIG. 10 shows a concrete example of the first part of the data creation processing S20 in the processed data creation device of FIG.
Data reading / creation processing (step S21), design intention addition processing (step S22), shape feature addition processing (step S23), and processing intention addition processing (step S)
24).

Of these, the CAD information 66 read in the CAD data reading / creating process S21 is simply a set of geometric elements (points, lines, arcs, ...).

In the design intention information 67 added in the design intention adding process S22, when the CAD information "shape" is viewed as a sheet metal design drawing, what design intention of the designer is included in each geometric element. It is what expresses. For example, outer shape, standard hole, standard outer hole, bending line, ...
Such. Also, product accuracy, design accuracy, etc.

The shape feature information 68 added in the shape feature addition process S23 is to add the feature information to the design intention information 67 from the viewpoint of actually processing the design intention information 67 by the processing machine. For example, standard holes → round holes, square holes, oval holes, etc. In addition, outline → straight line + joint + corner L
+ ... etc.

Further, the processing intention information 65 added in the processing intention addition processing S24 is the area to be processed by the tool from the shape characteristic information 68 (the area where the punching width has a degree of freedom because the mold is not determined). And the amount of joints, the joint of overtaking, the element for preventing scrap rising when squeezing, product accuracy, molding accuracy, and so on.

FIG. 11 shows a specific example of the second part of the data creation processing S20 in the processed data creation apparatus of FIG. 7, including machine-mounted mold group reception processing (step S25) and mold group selection processing (step). S26), tool locus creation processing (step S
27), and processing data creation processing (step S28)
It is composed of.

That is, the machine mounting die group reception process S25
Then, immediately before the processing, when the processing data (device intention) is instructed to the processing data creation device 94 in response to a request from the processing machine or the cell / line control device, both the mold mounted on the machine and the possessed mold are processed. Read mold group information. Here, the processing data creation request immediately before processing is an upload request from the host or a second part activation request from the processing machine. Further, the mold information stored in the list of the mold information (fixed information, update information) 50 corresponding to the shared code and the shared code 40 is a mold nickname (common name) that can be easily identified by the user. Including code.

Next, in the die group selection process S26, the machining intention information 65 is read, and a die is selected according to the machining intentions assigned to the "shapes" while being matched with the use intention information of the die. . Here, the intended use / function of the use intention information of the mold includes information for specifying a machine that can use the mold, and graphic information (shape of a non-standard mold such as a special mold).

Next, in the tool locus creating process S27, a tool locus information 69 is created by allocating dies corresponding to all machining intentions.

Then, in the processing data creation processing S28,
From the tool path information 69 to machining data (NC such as G code)
Program) 63 is created, and further material and die setup information 71 is created.

Further, as shown in FIG. 12, for example, when there is a data group of a die (punch P) that can be identified including the intended use, the machining data creation device 94 can adapt the die to the intended machining. A die group having an intended use is searched by using the shared codes “1”, “4”, ... “I” and the die information 50, and finally processed data is created.

FIG. 13 shows the machine mounting die information 70. The machine mounting die information 70 stores a set of machine storage numbers, machine positions corresponding to the respective storage numbers, die exchange path information, and the like. The stored station information is stored, the die unique code 20 and the shared code 40 corresponding to each storage number are stored, and the die group information for each die use intention corresponding to the shared code is stored. The storage number of the punch P and the storage number of the die D are stored so that the die (punch / die) can be individually identified, and the storage number is also stored when storing in the punch / die combination P / D state. To do. In particular, when the punch / die combination P / D is stored, it means one pair that is combined with the punch reference die clearance.

The usable holding molds which are not mounted on the machine are identified by the location information in the "unique code information". All owned molds can be recognized by "unique code information",
It can be said that the “machine mounting die information” is a part of the replication of the “unique code information”.

FIG. 14 shows punch / die selection at the time of setup and machining by the processing machine, and notifies the exchange instruction information to the die exchanging device corresponding to the storage number by the decided punch / die combination. To do. Further, the usage history is integrated during processing, and when the die is replaced, the update history corresponding to the unique code of each punch / die is integrated.

FIG. 15 shows the setting of an alternative mold as a concrete example of the mold / material setup process S30 in the NC apparatus of FIG. That is, the setting of the alternative dies is a group in which the shapes and sizes are the same as identifiable dies, the die clearance for the punch is within the specified range, and the die use intention corresponding to the processing intention is also matched, The use priority of the individual molds forming the group is determined.

As shown in FIG. 15A, for example, φ5
Explaining how to manage the group of dies, when the die clearance is set to CL 0.3mm depending on the material and processing method, N
It is assumed that o.1, No.2, and No.3 are grouped into one group. At this time, if there is an intention to use a material having a large pulling force because the material has a plate thickness of 3.2 t (use intention substitution), as shown in FIG. 15 (b), for example, No. 1 and No.
2 has a large plate pressing area, and if a spring having a large pulling force is adopted, the two will form a group.

Then, No. 1 and No. 2 are compared with each other according to the mold material, usage history, etc., and the priority order to be used is determined. For example, if No. 1 has a longer life than No. 2,
When product accuracy is required (use alternative), the one with the longer life (No. 1) is given priority. In addition, when demanding efficient use of molds (replacement of life), priority is given to the one that runs out faster (No. 2).

The alternative types include clearance alternatives in addition to application alternatives / lifetime alternatives. Further, it is possible to substitute the combination because of the relation of the shared code. The substitute information is usually automatically generated according to the mold use intention and the processing intention. When the user edits the generated information and inputs the editing intention, it is stored and used (learning function) for generation from the next time.

When there is no alternative next candidate, the standard → final candidate is continuously used. (By the user's selection, it is possible to set up even during processing.) Further, when the alternative information is edited during processing, only standard → edit is possible. (By the user's selection, it is possible to perform setup even during processing.) FIG. 16 shows a specific example of the punch / die calculation processing S40 immediately before the die replacement during processing in FIG. That is, in the case of normal processing, as shown in FIG. 16A, processing data reading / die code search processing (step S41), punch / die calculation processing (step S42), setup determination (step S43), die It comprises a mold setup process (step S44), information notification process to the mold exchanging device (step S45), and the next mold presence judgment (step S46).

Further, when changing the alternative mold information, as shown in FIG. 16B, it is constituted by a processing alternative mold information editing process (step S47) and an information updating process (step S48). Processing is performed in parallel with the punch / die calculation processing (step S40) immediately before the die replacement during processing.

Then, the next die presence judgment at the time of normal processing (step S46) and the information updating process (step S48) at the time of changing the substitute die information are synchronized.

As a means for realizing the unique code 20, it is general to use, for example, a two-dimensional code such as a data code, a QR code, a maxi code, a CP code, etc. It can be realized by using a dimensional code, but the invention is not limited to this. For example, an IC tag or the like using an electronic element is used to electronically transfer the unique code 20, the shared code 40 and mold information. It is also possible to store in the element.

As described above, according to the present invention, when registering the mold information of the mold purchased by the user, the user and the distributor of the mold are connected through a network to purchase the mold. By accessing the distributor using the mold ID, the mold information of the mold stored in the distributor is transferred to the user side and registered, so that the user can register the mold. Since it is not necessary to enter the mold information that was necessary for each purchase, it is possible to reduce input operation mistakes that occur when performing complicated data input, and for the mold management system on the user side. It is possible to unify the mold information exchanged between the included devices, and further verify whether the mold supplied by the distributor and the mold delivered to the user are completely the same. There is an effect that can be.
