Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mold management method for a punch press equipped with a mold selection and exchange device, and a mold management device.
[0002]
[Prior art]
In general, there are various types of methods for managing molds in a punch press equipped with a mold selection and exchange device. For example, by assigning a unique mold number to each mold and storing mold information (shape, size, etc.) of each mold corresponding to the mold number, managing each mold, Also, information specific to each of the upper die (punch) and lower die (die) (manufacturing time, number of uses, etc.) and set die information including die clearance when both upper and lower dies are set There are various types that manage the mold exchange based on the set mold information and others.
[0003]
[Problems to be solved by the invention]
However, all of these conventional products have a problem that no consideration is given to a mold that can be identified as intended. In other words, it is needless to say that the die must be managed individually for the punch and die, including the shape, size, etc., as well as the manufacturing time, number of uses, and re-polishing history. It is enough.
[0004]
For example, if you purchase two identical molds, they must be identified as individuals, but they are considered to be used for the same purpose, and can be identified as intended. There is no need to distinguish between the two, and they may be handled as the same mold. That is, as the mold data managed by the machining data creation device, both can be handled as the same mold, while as the die data managed at the machining site, the mold specified by the machining data creation device Either of the molds can be assigned to the data.
[0005]
In addition, even when using different types of dies, for example, when both are used for outer periphery cutting, the purpose of use (used for outer periphery cutting) is the same, so it can be identified as intended. In that sense, there is no need to distinguish between the two.
[0006]
However, the conventional ones are intended to be used because the molds are managed individually for both punches and dies, and in the case of set dies with punches and dies set, each set mold is managed individually. Even if they can be identified identically, they must be treated as separate molds (punch / die or set mold) so that the user is free to use the mold according to the user's intention The information that realizes the possibility of use cannot be used, and therefore the user's original usage method such as the mold identification memo that the user has used before is reflected in the mold management of the punch press. I can't.
[0007]
In addition to the above, the problem is that every time a user purchases a mold, various mold information about the mold attached to the mold supplied by the distributor is stored on the user side. Since it is registered as data in the mold management system, it is necessary to perform complicated and complicated mold information data input operation, and whether the attached mold information is the mold information of the purchased mold or not. That is, there is a problem that it is not possible to verify whether or not the mold supplied by the distributor is completely coincident with the mold delivered to the user.
[0008]
The object of the present invention is to eliminate the above-mentioned problems of the conventional ones, and it is unnecessary to input mold information when purchasing the mold, and the mold supplied by the distributor and the user's hand are delivered. It is an object of the present invention to provide a punch press die management method and apparatus capable of verifying whether or not the die completely matches.
[0009]
[Means for Solving the Problems]
This invention solves the said subject, The invention which concerns on Claim 1 is the die management apparatus of the punch press provided with the die selection exchange apparatus,
The mold management system provided on the mold user side and the mold management system provided at the mold vendor are configured so that data can be transferred via the network.
The mold management system of the seller comprises a mold information server that stores mold information of molds to sell,
The mold management system on the user side is
Means for reading the unique code of the mold purchased by the user,
By accessing the mold management system of the seller using the read unique code, the mold information including the mold information corresponding to the unique code transferred from the mold information server to the user side is obtained. A mold information server for registering mold information,
When the same mold as the mold having the unique code is purchased, the unique code of the new mold identifies the new mold, and if the purpose of use can be identified with the previous mold, the same shared code Even if the mold having the unique code and the shared code is different from the mold having the unique code and the shared code, if both have the same intended use, both share the same One mold has a plurality of intentions, and has a plurality of shared codes corresponding to the plurality of intentions, and each shared code stores corresponding mold information.

In this case, the individual code of the new mold (punch P2) is identified as “22222”, for example, but the individual code can be identified with the purpose of the previous mold (punch P1), so the same shared code “Z9876” Add. That is, the shared code “Z9876” of the previous mold (punch P1) is copied to a new mold (punch P2).
[0033]
Further, for example, a die (for example, the die D1) having the unique code “23456” and the shared code “Z8765” shown in FIG. 5A, the unique code “45678”, and the shared code “Z7536” shown in FIG. Even if the mold (die D2) having "" is completely different, if both have the same intended use (for example, to be used for peripheral cutting), as shown in FIGS. The same shared code (for example, “S5555”) is attached to both. As a result, two molds (die D1, D2) inheriting the attribute of outer periphery cutting are generated. In this way, a single die can have a plurality of usage intentions such as nibbling, overtaking, outer periphery cutting, notch, single shot,..., And thus has a plurality of shared codes corresponding to the plurality of usage intentions. be able to.
[0034]
Further, for example, in addition to the unique code shown in FIG. 6A, a die (punch P) having shared codes “1”, “4”... “I”, and the unique code shown in FIG. When combined with a die (die D) having a shared code “2” “4”... “J”, as shown in FIG. 6C, a punch / die combination having a shared code “4”. P / D is configured. Further, the combination of the punch and the die can be various combinations as shown in FIG. 6D depending on conditions such as die clearance with respect to the punch.
[0035]
FIG. 7 shows a flowchart 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 creation device. Data creation process (step S20), mold / material setup process in NC unit (step S30), punch / die calculation process (step S40) immediately before the mold change during processing, calculated punch / die exchange process (Step S50), punch / die use count update processing (Step S60), and processing end determination processing (Step S70).
[0036]
Among these, the mold introduction process S10 in the mold management apparatus inputs and stores the unique code 20 and the shared code 40, and inputs and stores the mold information 30 and 50 corresponding thereto. As an input method, a unique code 20 of a mold is read and stored by a bar code reader, a two-dimensional code reader, an RF-ID reader, or manual input, and a machining data creation device (for example, automatic programming device 3) or a machine (for example, Information used in the punch press machine 1) (shared code: die group management number, die information) is extracted and stored. Thereby, the correctness of the delivered metal mold | die can be confirmed. The shared code 40 can be easily added and changed by the user, and when added, the intention can be stored.
[0037]
Further, the data creation process S20 in the machining data creation apparatus creates machining data with the shared code 40 and the corresponding mold information 50, and transfers the used mold information / setup information to the NC apparatus. The machining data creation device is divided into two parts (first part and second part), and creates the CAM part / working intention data as before, while the processing machine is installed just before machining. The available mold information (mounting mold information) is transferred to the machining data creation apparatus via the NC apparatus. Based on this mounting die information, the machining data creation device creates or recreates the data of the mold information and setup information to be used, so that the setup can be reduced and the processing can be performed as intended. Forward.
[0038]
In addition, the mold / material setup process S30 in the NC apparatus performs the setup process using the used mold information / setup information attached to the machining data. In material preparation, materials necessary for processing are confirmed and allocated. Die set-up does not work with an installed mold to comply with the processing intent, but when a mold change occurs, or when replacing a mold related to mold life management, or when changing the setting of an alternative mold (mold This is done for the purpose of changing the content of intended use substitution information). The setting of the alternative mold can be changed during the machining in addition to the pre-setting before machining. Especially for the life replacement, the setting change such as replacement before the life or neglect of the life can be performed.
[0039]
The punch / die calculation process S40 immediately before the die replacement at the time of processing is to select a combination of punch / die to be used for processing by using die information / material information attached to the processing data. Select the mold group (mold intent substitution information) to be used for machining from the material, machining intent, and mold information to be used, and the contents of life substitution, clearance substitution, application substitution, etc. from the mold group. To select the punch / die to be actually used for processing. In addition, the mold can be selected in advance from the next and subsequent molds during processing, and the machine can be notified in advance. Furthermore, when performing mold replacement / maintenance during machining, it is possible to select again according to the progress of machining, including information notified in advance.
[0040]
Further, the punch / die use frequency update process S60 can discard the die information after the processing is completed or when the die is set up when it is determined that the lifetime is determined by the punch / die individual use history management. Further, when remanufacturing by re-polishing or the like, it is recorded in the maintenance record.
[0041]
FIG. 8 shows a specific example of the mold introduction process S10 in the mold management apparatus of FIG. 7, and the unique code reading process (step S11), the mold information reading process from the seller (step S12), and sharing. It consists of a storage process (step S13) of the code / mold information to the server. Here, with respect to the mold information reading process from the seller (step S12), in the case of a standard mold, a part of the information may depend on the server on the user side.
[0042]
FIG. 9 shows an example of an apparatus for realizing such a mold introduction process. In other words, a local network 81 provided in the mold management system 80 of the machine / mold vendor and a local network 91 provided in the user-side mold management system 90 are connected via the gateways 82 and 92, respectively. Connected via the Internet. A mold information server (for vendor) 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. A processing data creation device 94 and a processing machine / die information operating device 95 are connected. Then, the mold information (fixed information, update information) 30 corresponding to the unique code is read from the mold information server (for the user) 93, stored in the list of unique codes 20, and compatible with the shared code. The mold information (fixed information, update information) 50 is read and stored in the shared code 40 list. A unique code reading device 96 connected to the processing machine / die information operating device 95 reads the unique code 20 from the punch and die.
[0043]
FIG. 10 shows a specific example of the first part of the data creation processing S20 in the machining data creation device of FIG. 7, and CAD data reading / creation processing (step S21), design intention addition processing (step S22), and shape feature addition. It consists of processing (step S23) and processing intention addition processing (step S24).
[0044]
Of these, the CAD information 66 read in the CAD data reading / creating process S21 is simply a collection of geometric elements (points, lines, arcs,...).
[0045]
Further, the design intention information 67 added in the design intention addition process S22 indicates what design intention of the designer is included in each geometric element when the CAD information “shape” is viewed as a sheet metal design drawing. To express. For example, external shape, fixed hole, fixed outer hole, bending line, etc. Product accuracy, design accuracy, etc.
[0046]
Further, the shape feature information 68 added in the shape feature addition process S23 is to add feature information to these shapes from the viewpoint of actually processing the design intention information 67 with a processing machine. For example, standard holes → round holes, square holes, oblong holes, etc. Also, external shape → straight line + joint + corner L +, etc.
[0047]
Further, the machining intention information 65 added in the machining intention addition process S24 includes, from the shape feature information 68, an area to be machined by a tool (an area where the die width has been given a degree of freedom since the mold has not been determined), a joint It has the following elements: quantity, overshoot seam, debris prevention element when crushing, product accuracy, molding accuracy, and so on.
[0048]
FIG. 11 shows a specific example of the second part of the data creation process S20 in the machining data creation apparatus of FIG. 7, including a machine-mounted mold group reception process (step S25), a mold group selection process (step S26), It consists of a tool path creation process (step S27) and a machining data creation process (step S28).
[0049]
That is, in the machine-attached mold group reception process S25, immediately before processing, if the processing data creation device 94 is instructed by the request from the processing machine or the cell / line control device, the processing data creation device 94 is mounted. Read both mold group information of the mold and holding mold. Here, the machining data creation request immediately before machining is an upload request from a host or a second part activation request from a machining machine. Further, the mold information (fixed information, update information) 50 corresponding to the shared code and the mold name stored in the list of the shared code 40 are mold nicknames (common names) that can be easily identified by the user. Contains code.
[0050]
Next, in the mold group selection process S26, the processing intention information 65 is read, and the mold is selected in accordance with the processing intention assigned to the “shape” while matching with the usage intention information of the mold. Here, the purpose / function of the usage intention information of the mold includes information for specifying a machine that can use the mold, and graphic (shape of a non-standard mold such as a special mold).
[0051]
Next, in the tool trajectory creation processing S27, a tool trajectory information 69 is created by assigning a die corresponding to all the machining intentions.
[0052]
In the machining data creation process S28, machining data (NC program such as G code) 63 is created from the tool trajectory information 69, and further material and mold setup information 71 is created.
[0053]
Also, as shown in FIG. 12, for example, when there is a data group of dies (punch P) that can be identified with the intention of use, the machining data creation device 94 has a dies intention to use that can be adapted to the machining intention. The obtained mold group is searched using the shared codes “1”, “4”... “I”, and the mold information 50, and finally processing data is created.
[0054]
FIG. 13 shows machine mounting mold information 70. The machine mounting mold information 70 stores a set of machine storage numbers, a machine position corresponding to each storage number, mold exchange route information, and the like. The information is stored, the unique code 20 of the mold corresponding to each storage number, and the shared code 40 are stored, and the mold group information for each intended use of the mold 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 individual identification of the die (punch / die) can be performed, and the storage number is also stored when storing in the punch / die combination P / D state. To do. In particular, when storing in a punch / die combination P / D state, it refers to a pair that is combined with a punch-based die clearance.
[0055]
The available holding molds that 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”, and “machine mounted mold information” can be said to be a partial replication of “unique code information”.
[0056]
FIG. 14 shows punch / die selection at the time of setup and processing on the processing machine, and notifies the die changer of replacement instruction information corresponding to the storage number by the determined punch / die combination. Further, the usage history is integrated during machining, and when exchanging dies, the usage history of the update information corresponding to the unique code of each punch / die is integrated.
[0057]
FIG. 15 shows setting of an alternative mold as a specific example of the mold / material setup process S30 in the NC apparatus of FIG. In other words, the alternative molds are set as a group of molds that have the same shape size as the molds that can be identified, the die clearance with respect to the punch is within the specified range, and the mold usage intentions corresponding to the machining intentions also match. The usage priority order of the individual molds forming the group is determined.
[0058]
As shown in FIG. 15A, for example, the group management of a φ5 die will be described. When the die clearance is set to CL 0.3 mm depending on the material and the processing method, No. 1, No. 2, and No. 3 are Suppose they are grouped together. At this time, when there is an intention to use a material having a large pulling force due to the plate thickness of 3.2 t (substitution of intended use), for example, as shown in FIG. If a spring with a large pull-out force is used, the two will form a group.
[0059]
Then, No. 1 and No. 2 are compared according to the mold material, usage history, etc., and the priority order to be used is determined. For example, if the life of No. 1 is longer than that of No. 2, when the product accuracy is required (use replacement), the one with the longer life (No. 1) is given priority. In addition, when efficient use of the mold is required (life replacement), priority is given to the one whose life is exhausted earlier (No. 2).
[0060]
As alternative types, there are clearance alternatives in addition to application alternatives and life alternatives. Also, the combination can be replaced due to the shared code. The substitute information is usually automatically generated according to the intention to use the mold and the intention to process. When the user edits the generated information, if the editing intention is input, it is memorized and used for generation (learning function) from the next time.
[0061]
When there is no alternative next candidate, continue using the standard → final candidate. (It is assumed that it can be set up during processing at the user's selection.) Also, when editing alternative information during processing, only standard → editing is possible. (It can be set up during processing at the user's choice.)
FIG. 16 shows a specific example of the punch / die calculation process S40 immediately before the die change at the time of processing shown in FIG. That is, during normal machining, as shown in FIG. 16 (a), machining data reading / die code retrieval processing (step S41), punch / die calculation processing (step S42), setup determination (step S43), gold It consists of a mold setup process (step S44), an information notification process to the mold exchanging device (step S45), and a next mold determination (step S46).
[0062]
Further, when changing the alternative mold information, as shown in FIG. 16B, a process constituted by an in-process alternative mold information editing process (step S47) and an information update process (step S48) is performed. The processing is performed in parallel with the punch / die calculation processing (step S40) immediately before the die change during processing.
[0063]
Then, the next determination that there is a mold during normal machining (step S46) and the information update process (step S48) when changing the alternative mold information are synchronized.
[0064]
As a means for realizing the unique code 20, for example, a data code, QR code, maxi code, CP code or other two-dimensional code is generally used, and the same two-dimensional code is also used for the shared code 40. However, the present invention is not limited to this. For example, the unique code 20, the shared code 40, and the mold information are stored in the electronic element using an IC tag using the electronic element. It is also possible to make it.
[0065]
【Effect of the invention】
As described above, according to the present invention, when registering the mold information of the mold purchased by the user, the user side and the vendor of the mold are connected via the network, and the ID of the purchased mold is used. By accessing the distributor, it is configured so that the mold information of the mold stored in the distributor is transferred and registered to the user side, so it is necessary every time the user purchases the mold. This eliminates the need to input complicated mold information, which can reduce input operation errors that occur when complicated data is input, and between each device included in the mold management system on the user side. It is possible to unify the mold information exchanged at the site, and to verify whether the mold supplied by the seller and the mold delivered to the user are completely the same There is.
