2. Description of the Related Art Due to the rapid development and diversification of electronic devices in recent years, it is urgently necessary to shorten the development period, and it is required to shorten the manufacturing period of press die manufacturing, especially the die design time. As an effective means for shortening the die production period, there are standard die sets and standard die parts that are standardized for each part of the press die and marketed by a specialized manufacturer.
The use of standard die sets and standard die parts has become an indispensable means for shortening the die delivery time, and its importance is increasing.

A press die manufacturer, generally called a die maker, processes punches, dies, strippers, etc., which are directly related to the shape of a press part, and incorporates them into a commercially available die set and adjusts the press die. To complete. Machines owned by press die manufacturers mainly perform electrical discharge machining, wire cutting, precision boring, jig grinding, shape grinding, etc. in order to efficiently process main components of complicated shapes such as punches and dies. There are a lot of special machines, and the hourly wages of employees are usually high.

General-purpose parts for die sets and press dies are
Usually purchased from a specialized manufacturer of mold parts. For these die sets and general-purpose parts, the outline of the press process (strip layout) and press die format is determined from the shape of the press part (product) formed by press working, and the size of the press part and the press machine used. The plate thickness of plates such as a mold plate is determined from the specifications and the like, and the outer dimensions of the mold are determined mainly by the planar shape and arrangement (strip layout) of the product.

As a press die manufacturer, when inserting a die set or die parts, depending on the above-mentioned product shape, the die is subjected to secondary processing such as different hole machining and engraving of plates to make small products. Once the parts are installed and delivered, we can concentrate on the core business of manufacturing punches, dies, punch pads, strippers, and other main parts. Ideally, the completed punches, dies, punch pads, strippers, and other main parts should be assembled into a die set that has undergone secondary processing and small parts are attached, and adjustments and trial punches should be performed to complete the mold.

Secondary processing of die sets and general-purpose parts often requires the use of general-purpose machines such as general drilling, internal and external cylindrical grinding, and surface cutting / grinding, and it is profitable at the hourly rate of press die manufacturers. Often disadvantageous. In addition, performing secondary processing on the press die manufacturer side after purchasing a die set or general-purpose parts is disadvantageous in terms of die manufacturing schedule. Therefore, the standard secondary processing of these die sets and general-purpose parts is performed by the specialized manufacturer, and the die set and general-purpose parts that have undergone the secondary processing are delivered to the mold manufacturer, which is cost effective. It is also considered advantageous in terms of manufacturing schedule.

As a specialized manufacturer of mold parts, the present applicant sells its own standardized die set, and has a track record of meeting the demands of long-pension type manufacturers, and the applicant's standard is almost an industry standard. Has a proven track record. In addition, standard plates of various materials for press dies are prepared, and shanks, knock pins, bolts, springs, etc. are listed in the catalog as small standard parts, which makes it even easier to use.

The standard die set marketed by a specialized maker shortens the period from the design of the press die to the die production and facilitates the die design of the die manufacturer who is the user. Not to mention JIS standard products, standardize non-standard die sets, plates, parts, and additional processing respectively, standardize die sets, plates, parts, and additional processing (symbolize product name and processing), catalog specifications It is possible to place an order for a standard die set by creating a product that can be said to be, and instructing the product specifications mainly based on the product name symbol such as the standard die set described in this catalog standard document. .

For example, in the case of the present applicant, this catalog standard document is roughly divided into a standard die set, plates, small parts, and three parts, and the standard die set includes all secondary processing. It also includes a full processing die set to perform.

The structure of the die set and the schematic structure of the progressive die will be described by taking as an example one series of steel die sets which are often used in the progressive die. FIGS. 6A and 6B are projection views showing the outer shape of an example of the steel die set.

Holder (top) 51, which is a substantially rectangular thick plate
Cylindrical guide bushes 54 are fixed to the four corners of the above, and cylindrical guide posts 53 are fixed to a holder (upper) 51 and a holder (lower) 52 that is in the same plane. Although details will be described with reference to FIG. 7, the holder (upper) 51 is movable up and down (left and right in FIG. 7B) with respect to the holder (lower) 52. The size of the holder (planar dimension and thickness) and the type of guide bush are classified, and there are hundreds of types in the catalog of this series.

Referring to FIG. 7, a progressive die structure using the above die set will be described. FIG. 7 is a sectional view showing a die structure in a punching process which is a typical process. The projection direction in FIG. 7 is the same as that in FIG. 6 (b).

A progressive die, which is one type of press die, includes a plurality of stage die parts such as punching (step), outer shape punching (step), bending (step), drawing (step) and the like.
As an example, a punching step of making a hole in a strip made of a material, which is a typical step shown in FIG. 7, will be described with reference to FIG. 7 which is a schematic cross-sectional view of a progressive feed type punching stage.

The die set 50 is assembled with parts 51 to 54, a guide bush 54 is fixed to a holder (upper) 51, and a plurality of guide posts 53 are attached to the holder (lower) 52.
Is fixed. When the hole of the guide bush 54 and the outer diameter of the guide post 53 are slidably fitted and guided vertically, when the die set 50 is attached to the press machine, the holder (bottom) 52 is held against the holder (top). ) 51 reciprocates up and down.

The backing plate 5 is attached to the holder (upper) 51.
5 and punch plate 56 are positioned by dowel pins 62 (which are parallel pins) and fixed by bolts 61. The backing plate 55 and the punch plate 56 hold the punches 60 and 60a at predetermined positions. The die plate 58 is attached to the holder (bottom) 52 by the dowel pin 62.
Positioned with a and fixed with bolts 62a. The stripper plate 57 is positioned on the die plate 58 by the dowel pin 62b and fixed by the bolt 61b. The progressive die attached to the press machine is such that when the ram of the press machine is lowered to the lowest position, the cutting edges at the tips of the punches 60, 60a are inserted into the cutting edges (58a, b) of the die opened in the die plate to an appropriate length. It

A strip 64 (a strip of press material) is inserted into the recess of the stripper plate shown (the short side of the strip is shown), the pilot holes are punched out in the first stage, and after each stroke of the press machine. Then, the sheet is fed at a predetermined pitch from the front side to the other side at right angles to the paper surface in the figure. The pilot pin is inserted into the pilot hole of the strip to regulate the feed amount of the strip.

In the punching step (stage) shown in the figure, the cutting edge portions of the tips of the punches 60, 60a lowered by the press machine and the cutting edge (5) of the die opened in the die plate.
8a, b) make a hole in the strip and
The same as the shape of the tip of the punch) falls into the cutting edge of the die, and is discharged through the scrap clearance holes 63, 63 formed in the holder (lower) 52.

In order to design such a press die, the design department of the die maker often uses a commercially available CAD system. A commercially available CAD system for a mold can be made into a drawing by setting an arbitrary value by a designer, and is not particularly configured to use the applicant's standard die set, standard plate, and small parts. Designers know that if standard products are used, there are merits in delivery time and cost, but it is quite troublesome to extract usable die sets and mold parts from the catalog.

The applicant's standard part selection support system for molding dies has been distributed to users. As shown in the flow chart of FIG. 5 (a), numerical values are read from CAD data and the applicant's standard parts are read. It is necessary to search for the corresponding model from the standard parts database and transfer it to the product code of the applicant.
It will be transferred to a commercial CAD system. It is a rather tedious task, and a designer who is unaware of the advantages of Applicants' product does not want to use standard components. Even if a similar support system is made for the press die, it is unlikely that the user will use it immediately.

Therefore, at present, as shown in FIG. 2B, the designer selects a model from the model component database installed in the commercially available CAD system, inputs parameters, and creates a drawing. Drawings can be easily created and design work is easy, but there is a strong tendency for custom delivery and cost delivery to increase.

Further, when receiving an order for a die set, a plate, etc. including secondary processing, the applicant's ordering system is to make an order by symbolizing the processing contents, including the mold base for the molding die. Has become. For example, the basic format is written as "MBC SA 1515 30 30 60 SVB N", and then the symbol string for secondary processing follows.

In the example described above, the holder (bottom) 52 of the die set 50 has a counterbored hole for the bolt 61a, a hole for the dowel pin 62a, and a clearance for the dowel pin 62b in the punching stage shown in FIG. Hole, dust escape hole 6
3 and 63 are required, and when each stage of the strip layout is integrated, a large number of various holes are required as shown in FIG. 6 (c). If all of this is symbolized, it becomes a list of hundreds of symbols, and at first glance it is impossible to know what the specifications are.

When a manufacturer specializing in die sets and mold bases receives an order by this method, it can easily process the die sets on the production line by decoding the symbols. However, due to diversification of molds (for example, the number of items in the applicant's standard is more than 20 million types), the number of letters of the product name symbol will dramatically increase as the number of orders for option specifications increases. It has become longer and the merit of symbolizing the product name has diminished.

In particular, in the all-processing die set which performs all the secondary processing and delivers it to the user, the processing drawing is obtained from the user and the meeting is performed before the processing, but there is little erroneous processing due to a mistake in reading the drawing. Absent. If the NC data of the MC (machining center) is created from the CAD data of the user side, there is no risk of erroneous processing.

[0025]

In order to deal with various high-level additional machining associated with press die manufacturing, the current method of machining instruction by the product name symbol indicates to the user whether the machining is handled by the manufacturer. In addition to having to decide whether or not to deal with it, even if it were to deal with it, the number of instruction elements increased and the product name symbol became extremely complicated and redundant, making it difficult for the customer to understand and prone to error.

In addition, this catalog-like mold design support system mainly composed of standard mold bases, die sets, and standard parts is a machining symbolized as a catalog standard of the mold maker that provides the design support system. Since it is limited to the specifications, the mold design cannot be completed. Further, for a specialized maker, when dealing with a new machining specification, a large amount of time and man-hours are required in the preparation period for symbolizing the machining specification and issuing a catalog, so that it is not possible to respond promptly.

Further, in the all-processing die set which performs all the secondary processing and is delivered to the user, the processing specifications that are not symbolized as the present applicant's catalog standard have many specification-determining factors. As for specifications, one processing specification expression requires more than 20 parameters (100 characters or more in terms of the number of characters), and it is clear from the point that it is an expression that is easy to understand for humans, which was one aim in conventional symbolization. It will deviate. Therefore, it is difficult to standardize the slide core machining catalogue.
Also, many pages are required to explain the specifications on the catalog,
It is also difficult for the customer to understand the specifications.

A file including the standard die set selected in the design support system and the additional specification instruction content is converted and read by a commercial CAD system, and then the change related to the standard die set or the additional specification instructed by the design support system side. If you need, go back to the design support system again,
It was necessary to re-select standard die sets or additional specifications to re-pass the design data to a commercial CAD system.

In addition, the transmission of design information (ordering information) is
Since it is sent to the processing / processing step intermittently once, there is also a problem that it is not possible to respond to an additional processing request from the user side by sending the order information again.

BEST MODE FOR CARRYING OUT THE INVENTION A press die design support system of an embodiment for realizing a press die designing method or a press die designing apparatus of the present invention has the following functions. 1. Product CAD data reading function. 2. Automatic drawing function with high flexibility of mold parts based on design parameters. 3. Standard parts matching function. 4. Replacement confirmation function. 5. Replacement execution function. 6. Mold parts ordering function.

First, the operating condition of the press die design support system according to the embodiment of the present invention will be described with reference to the flowchart of FIG. This flow chart is shown including work divisions at the time of manufacturing the press die on both the user side, which is the press die manufacturer, and the professional manufacturer, which is a specialized manufacturer of standard die sets and general-purpose die parts.

The order of the press die is usually made by the press die manufacturer to the press die maker, and the press die maker is often requested by the end user to produce the press parts with the product drawing. Therefore, it may be considered that the product design has already been completed (S1). Recently, product shape data is often transferred in the form of CAD data. Even in the design department of a die maker, it is common to introduce a commercially available CAD system to perform die design. The type of press machine used at the same time is usually instructed by the press processor.

Process design is performed in the initial stage of designing the press die, and the strip layout is determined from the size and shape of the product, the capability of the press machine, etc. (S3). At the same time, the work area is set. At this point, the schematic plane shape of the die set and the plate thickness of the main plate are set (S4).
Up to this point, the designer arbitrarily sets each dimension of the die set. As will be described later in detail, the matching function of S5 in the present support system searches for a standard die set having a similar specification and replaces it with the numerical value of the standard die set, and the subsequent design is performed. If it cannot be used, proceed with the design using the initial values.

Subsequent to the determination of the die set, plates and small parts are designed (S6, S8). Here again, the standard plate and standard parts are selected by the collating function (S7, S9). In this way, when each mold part is determined, an order is placed (S10), and the specialized manufacturer makes a die set,
Started main processing and secondary processing of plates and small parts (S1
1) Do.

On the maker side, major die parts such as odd-shaped punches, dies, strippers and punch holders are manufactured (S1
2) Incorporate it into the die set that has been secondarily processed by a specialized manufacturer. After the assembly adjustment (S13), the press die is completed.

If the standard die set is selected, the specialized manufacturer can start the standard processing of the first stage when the user places an order. The system is designed to support step-by-step detailed machining instructions, so that machining can proceed even before the design is completely completed.

On the professional manufacturer side, this mold design support system can be used in various ways for estimation, process design, NC data generation, delivery date reply, and the like. By extracting the shape to be processed from the data of this system and referring to the attributes necessary for processing,
Quotation work and delivery date answers can be performed without human intervention. Furthermore, it is easy to generate individual NC data.

Next, a description will be added to the press die design support software. First, this design support software has the same function as a general press die design support CAD, and can 100% support the die design work of the designer. Bending development function, drawing calculation function, strip layout, mold structure design, split plate design, plate design, standard part mounting design (template, parameter setting, plate free), special parts, which are support functions required when designing a press die. It has the functions required when designing the press die such as mounting design. With the above-mentioned function, it is possible to determine the specifications of the mold, and as a result, create a part drawing and a drawing.

It has a standard mold part collating function which is a characteristic peculiar function of this software. At each design stage, the user (die manufacturer) designer investigates the specifications of the die parts (die set, plate, parts) that are arbitrarily designed by the template and parameter settings, and collates with the standard part master, Performs the following standard component matching function operations.

After checking, if there is a conforming product, the mold parts arbitrarily designed by the user are replaced with standard products. Even if they do not meet the specifications, they are close to the specifications, and if the designer finds that they are within the design allowable range, replace them with standard parts. This standard part matching function is performed in the following three stages.

In the first die set collation, work area size collation, plate thickness collation, external size collation, guide size collation, guide format collation, guide layout pattern collation, guide position collation are carried out, and they are compatible products and allowable ranges, respectively. Goods are extracted. In the next plate matching, material matching, width size matching, plate thickness size matching, and length size matching are performed, and compatible products and allowable range products are extracted, respectively. In the third part collation, the name, (material collation), diameter size collation 1, (diameter size collation 2), (diameter size collation 3), and length size collation are performed, and compatible products and allowable range products are extracted. To be done.
Do not perform items enclosed in parentheses unless necessary.

Each verification procedure will be described in detail. The first is a standard product collation method when designing a die set, which will be described with reference to the flowchart of FIG. (1) Die set plane outline frame drawing (S21) Operation: Draw an appropriate rectangular diagram on the plan view using the drawing function, and recognize this as the die set outline frame / work area (basic plate size). System processing: Reads the width and length dimensions from the drawing and stores them in the memory. (2) Die set plate thickness / material setting (S23) Operation ... Set the plate thickness / material of the die set constituent plates (one each on the top and bottom) to an appropriate value with the input box. System processing: At the same time as making a figure based on the set numerical value, this is stored in the memory. (3) Guide post drawing (S27, S28) Operation: Select an appropriate guide post / guide bush from the mold part setting menu and place it at an appropriate position. System processing: Stores the set part name and dimensional value of each part on the memory.

(4) Standard die set collation processing operation--Selects the collation start menu. Alternatively, select the menu indicating that the die set design is completed. System processing: Compares each stored setting value with the standard product database and extracts a compatible die set. When the matching process is started, the matching is performed in the above order.
As shown in FIG. 2, it is possible to collate the results so far at an intermediate stage, and there is an advantage that the deviation from the standard die set is smaller than that of collating after designing to the end.

Referring to FIG. 2, description will be given of a case where the collation is performed at a necessary place each time. No collation is performed when the work area is set in S21. Assuming the width, length, thickness, and material of the die set (S23) and performing matching, if there is a compatible die set, set the guide post / bush as it is (S2).
Proceed to 5). When there is no compatible product, the closest standard die set is presented in S31 and approval is requested (S32). If approved, the dimensions and materials of the die set will be replaced as standard (S3
2). If not adopted, it is registered in the order information as a custom-made die set (S40).

The same procedure is executed for collation (S26) and collation (S
In step 28), the closest specification is presented when there is a conforming product and when there is no conforming product, and whether the product is standard or custom-made is adopted at each stage. Ultimately, it is decided whether the standard die set will be used or a custom-made product will be used. In this way, if the collation is performed at each stage, some dimensional correction can be performed without resistance.

A similar method is used when designing the main plates such as the second punch plate, die plate and stripper plate. The contents of plate matching are material matching, width size matching, plate thickness size matching, and length size matching.
This will be described with reference to the standard plate matching process in FIG. (1) The width and length of the plate are determined in the plate outline drawing of the plate. Operation: Use the drawing function on the plan view to draw an appropriate rectangular diagram and recognize it as the plate outline frame. System processing: Reads the width and length dimensions from the drawing and stores them in the memory. (2) Plate thickness / material setting (above S51). Operation: Input the plate thickness and material of the constituent plate B
Set appropriate value with ox. System processing ・ Graphs based on the set numerical values and at the same time stores them in memory.

(3) Standard plate matching processing operation: Select the matching start menu. Alternatively, select the menu indicating that the plate design is completed. System processing: Each stored setting value is compared with the standard database, and a suitable standard plate is extracted. In the same procedure as in the previous section, the verification (S52) is performed, and if there is a conforming product (S52 ... Y), the nearest specification is presented when there is no conforming product (S55). If approval (S56 ... Y), the plate dimensions・ Replace the material with the standard value (S57) and deny (S56)
・ ・ N), custom plate order (S58) and standard / custom order are distinguished.

The third part collation follows the flowchart of the standard part collation processing of FIG. Reference items are names,
These are (shape) matching, diameter dimension matching, and length dimension matching. (1) Drawing operation using the parts installation menu: Select standard parts from the parts installation menu and place them on the drawing. System processing: A menu selection result, a name and a diameter dimension are set, and when they are arranged on the screen, a length dimension is calculated from a plate thickness of a related plate and stored in a memory. (2) Standard parts matching processing operation: Select the matching start menu. Alternatively, select the menu indicating that the part design is completed. System processing: Each stored setting value is compared with the standard product database, and compatible standard parts are extracted.

Similar to the plates, collation (S62) is performed, there is a conforming product (S62 ... Y), presentation of the closest specification when there is no conforming product (S65), approval (S66 ... Y).
If so, the length of the part is replaced with the standard value (S67), and if it is denied (S66 ... N), the custom part is ordered (S68).

[0055]

As can be understood from the above description, according to the present invention, when designing a die set, a plate or a part as a die part, a design worker has a large number of standard metal molds prepared. It is possible to design a mold part by inputting arbitrary design parameters according to the design purpose without considering the mold part.
Therefore, for example, it is not necessary to have knowledge about a large number of standard mold parts prepared, and the design can be advanced without performing a troublesome search for finding a standard mold part that matches the design. . Then, for the designed mold parts designed by the parameter input of the designer, a suitable standard mold part or a standard mold part with similar specifications is searched for, and an appropriate standard mold part exists. If so, it can be replaced with it, so that standard parts can be used for the mold parts according to the design. Therefore, the use of standard parts as used parts is promoted. That is, according to the present invention, the troublesome work of finding a standard part that matches the design purpose is unnecessary, which greatly simplifies the design work and promotes the use of standard mold parts. It is possible to obtain the effects of cost reduction and delivery time reduction by using mold parts.

Further, when replacing the design mold part with the standard mold part, the operator can select whether or not the replacement process is possible, so that the design work can be most appropriately advanced. For example, if you want to use standard mold parts at the maximum, or if it is prioritized to design using custom-made parts rather than the above effects of using standard mold parts, you can flexibly adapt to actual design circumstances. You will be able to proceed with the work.

Further, according to the recording medium of the present invention, it is possible to easily realize a design system capable of exhibiting the above effects,
It can also promote its spread.
