Description

DETAILED DESCRIPTION OF THE INVENTION The present invention generally relates to a simple press mold and a method for manufacturing the same, and more particularly to a simple mold suitable for high-mix, low-volume production and a method for manufacturing the same.

In general, in press processing, the Toga of the blank used for press processing is Depending on the thickness of the sheet, a mold set consisting of two or more molds that are unique to each pressing process and used in combination with each other is used. The plurality of molds constituting one mold cellar) must be individually designed and precisely manufactured according to the intended processing content, and must be precisely mounted on a press machine. The use of imprecisely made molds, or even if the molds are precisely made, the use of imprecisely installed molds will impair the precision of the pressed product and reduce the product yield. let Therefore, when creating multiple molds that make up a mold set, it is necessary to precisely align the molds, and the press equipment Nt.
Even today, the work of precisely aligning the parts when installing them is still largely dependent on the work of skilled workers.

Originally, press processing was developed and developed to mass produce products with the same shape and dimensions. Each of the at least two molds constituting such a mass production mold set is generally composed of a plurality of parts. To explain this in more detail regarding the Lux mold set for outline cutting and shear processing, the upper mold includes at least a die set for the upper mold, a punching plate, and a punch, and the lower mold includes at least a die set for the lower mold and a die. A punch having a desired cutting edge shape and dimension is planted in a hole formed in the punch grate and having the same shape and dimension as the base end on the opposite side of the cutting edge of the punch, and the punch is placed on one side of the hole. It is rigidly supported and the opposite side is polished as necessary to form a unitary assembly.

The die set for the upper mold includes a block-shaped main body having a support surface that contacts and supports the opposite surface of the assembly, and a cylindrical shank integrally formed with the main body on the opposite side of the support surface. The above assembly is integrally fixed to the die set for the upper die by a plurality of tightening screws and a plurality of dowel pins through a plurality of holes into which they are received, thereby forming an upper die. The die has a cutting edge shape with a desired clearance with respect to the cutting edge shape of the punch, and the punched out product is placed on the opposite side (7,) of the cutting edge with ample space. There is. The die set for the lower die is a block-shaped part having a support surface that comes into contact with and supports the opposite side of the die, and the die has a plurality of tightening screws and a plurality of screws attached to the die set for the lower die. With a dowel pin,
They are fixed together through a plurality of holes to form a lower mold. Such a die set usually also includes a stripper for removing the press blank from the punch, but the stripper will not be explained here to simplify the explanation. In the above mold set, the upper mold die set and the lower mold die set have a guide post installed on either side to relatively guide the mold set to the bud during pressing work. The other end is provided with a guide bushing so that they are slidably fitted together.

The conventional manufacturing direction of the above-mentioned mold set was as follows.

A punch block is roughly machined to be larger than the desired shape of the cutting edge, hardened, and then precisely cut and polished to form a punch. Processing before quenching makes cutting easier, and processing after quenching reduces deformation due to quenching.
Apply 1 step pressure. It is now possible, especially for small punches, to form the desired cutting edge pattern from a pre-hardened blank using reverse electrical discharge machining techniques. In order to form a hole in the punch plate for mounting a punch, a small hole is roughly machined in advance in the punch plate blank, and after hardening, the hole is precisely cut and polished. Nowadays, especially for small punching tools, it is possible to form holes for planting from pre-hardened blanks using wire-cut electrical discharge machining techniques. The proximal end of the punch is planted from one side of the punch plate where the holes for planting are formed, and the two are assembled integrally by filling, brazing, etc., and the other side is smoothed as necessary. Polished to The assembly thus obtained is made by bringing the other side into contact with the upper die set before attaching it, and opening the plurality of holes correspondingly formed in the punch plate and the upper die set in advance. In order to prevent the abutting surfaces from shifting, a through hole is made in the die set and the punch grate, and seven holes are driven into the die set to completely integrate the die set and the punch grate.

Depending on the material of the die set, the magnitude of the load during press operation, etc., a backing grate with high hardness may be further interposed between the punch grate and the die set. The cutting edge of the die is formed to have a desired clearance with respect to the shape and dimensions of the punch's cutting edge, or is roughly machined to be smaller than the final shape of the cutting edge, and after quenching is precisely cut.

Polished. At this time, precise alignment between the cutting edge pattern of the punch and the cutting edge pattern of the die is performed by a skilled worker. The manner in which the die and the die set for the lower die are integrally coupled and fixed is generally the same as the method for coupling and fixing the punch plate and the die set for the upper die described above. However, as mentioned above, the die set for the upper mold and the die set for the lower mold are uniquely positioned by the E-bost and the guide bushing, so the ij wrench cutting blade pattern already fixed to the upper mold is It is necessary to precisely determine the position 11 of the die on the lower mold die set and fix it by averaging the clearance given to the cutting edge of the die.

For this purpose, roughly corresponding holes are formed in the die set for the goo and the lower mold in advance, and the tightening screws are loosely tightened to test-cut newspapers or soft 6'6 blanks.
Apply glue from the − side and observe the light leaking from the clearance between the cutting edge of the punch and die.
After positioning, tighten the tightening screw firmly, and then drive a dowel pin through the hole in both to completely integrate them.

This alignment work determines the quality of the mold set, so it is an extremely important work in the production of conventional mold sets, and must rely solely on the skill of experienced workers.

In this way, the mold center made with precise alignment is installed in the press equipment, and the upper mold shank is fitted into the four shank receiving parts of the press equipment, tightened and fixed, and then the lower mold is attached. Tighten and fix on the mounting table of the press device. At this time, even if the lower mold is slightly inclined with respect to the axis of the shank of the upper mold and the guide post or the guide post installed on the upper mold is slightly inclined with respect to the axis of the inner sleeve, the guide post will obstruct the smooth sliding movement between the lower mold and the upper mold. However, not only can a good pressed product not be obtained, but the mold itself may be damaged. Therefore, the attachment of the mold set to the press apparatus also had to rely on the skill of a skilled worker.

Precise alignment during the production of mold sets as described above increases the mold manufacturing time and therefore also increases its manufacturing cost. In addition, precise alignment during the installation of the die set into the pressing machine as described above increases the setup time before the pressing operation, and therefore also increases the manufacturing cost of the pressed product. In addition, this type of mold has a large number of parts,
In addition, the die set in a mold set occupies an extremely large volume and weight, so when high-mix, low-volume production is desired, not only does the material cost of each mold set increase, but the die set also occupies an extremely large volume and weight. Handling is inconvenient and storage space is also a significant cost factor. Furthermore, since a mold set for each press process is produced individually, it is impossible to create identical mold sets for several sets of paddy. This is inconvenient when installing a plurality of progressive lines and a plurality of transfer lines for press products that are completed through a plurality of press processes.

In order to easily and quickly attach a mold to a press machine, the so-called Q,Do system (Quick Die C!hange System) has been introduced since 11J for more than 10 years.
) began to be used. This system is based on the use of a press device for QDC molds. A press device for a QDC mold has a pair of mold mounting parts that receive and uniquely position a standardized base root that constitutes a part of the mold. The mold mounting portion is precisely guided so as to be relatively movable by a guide post and a guide bush provided on the press device. Unique positioning of the base grate is performed by removably providing a plurality of location pins on each mounting portion, providing location holes in the number and arrangement corresponding to the base grate, and fitting them. That is, the press device for the QDC mold can be considered as the press device 4 incorporating die sets for the upper mold and the lower mold in the above-mentioned mold center. However, in the conventional press equipment mentioned above,
The lower die set and the lower die attachment part of the press machine are not directly and uniquely positioned, but the shank of the upper die set allows the upper die set to be aligned with the axis of the shank with respect to the press machine. positioned with respect to the direction;
The lower mold is positioned with respect to the positioned die set of the upper mold and fixed to the lower mold mounting part of the press apparatus. In other words, the orientation of the mold is not determined uniquely (J).On the other hand, in the press equipment for QDO molds, the location pins provided in the upper and lower mold mounting parts are precisely The pace plates that form part of the upper and lower molds are positioned with their central axes aligned, and are positioned directly by the upper and lower mold mounting parts, respectively, and at the same time are integrated with the base plates. For example, even the orientation of the cutting edges of punches and gougers is uniquely determined.

An example of a QDO mold set and a method for manufacturing the same will be further described below regarding a shape cutting shear mold set.

The upper mold includes at least a punch, a punch plate, and a standardized base grating. The lower mold includes at least a die and a standardized pace plate.

The production of the upper mold is almost the same as the production of the conventional mold described above, but a case where this is produced using electrical discharge machining technology will be briefly described below.

A pre-quenched rectangular punch blank is placed in a reverse electrical discharge machining machine, and a discharge aperture with the shape and dimensions necessary to form the desired punch cutting edge pattern is machined. A punch is formed using the electrode.

Next, a pre-hardened blank with a rectangular plate surface for a punching plate is prepared, and two adjacent sides of the rectangular plate surface are polished so that they form precisely right-angled surfaces. A plurality of screw holes having a number and arrangement corresponding to the screw holes for receiving a plurality of positioning screws, which will be described later, are formed on the base grate using these two right-angled sides as the base;
Pre-cut small holes in the area where the hole for planting the proximal end of the punch is to be formed with the desired placement and orientation with respect to them, and then insert the blank into the two perpendicular sides. It is set in a wire-cut electrical discharge machining apparatus as a reference, and a discharge wire is sequentially inserted into the small holes to precisely machine each of the holes to form a punch plate. The proximal end of the punch is planted on one side of the plate surface of the punch grating obtained in this way, and they are combined and fixed into one body by filling, brazing, etc., and the punch grating is fixed as necessary. Sand the other side. The assembly of the punch and punch plate thus obtained is almost the same as the assembly of the punch and punch plate plate in the conventional mold described above. Next, a pre-hardened blank for the east flat plate with a standardized rectangular plate surface that can be inserted into the upper mold mounting part of the flat plate is prepared, and the base grade is set to J using the same procedure as for the punch plate. It will be accomplished. The difference is that there are location holes with a number and arrangement corresponding to the plurality of location pins in the mold mounting portion of the freeless device, and the assembly of the punch and punching plate is positioned at approximately the desired position with respect to them. A plurality of screw holes for receiving screws for positioning and tightening are formed.

The production of the die and the base plate that can be integrated with the die is also almost the same as the production of the punch plate described above. The base grate has location holes with a number and arrangement corresponding to the number of location pins in the mold attachment part of the press machine, and a number of positioning and tightening holes with a desired arrangement and orientation with respect to them. and the die is formed with a plurality of threaded holes formed in the pace plate and corresponding in number and arrangement to receive the number of positioning and fastening screws. The difference is that the threaded holes and the desired arrangement and orientation with respect to them form the cutting edge of the die with the desired clearance with respect to the cutting edge pattern of the punch. From the above, the alignment between the punch cutting edge and the die cutting edge is the alignment between the punch and the punching grade, the punching grade and the paste route, the base route and the upper die attachment part of the press machine, and the alignment between the upper die attachment part and the lower die attachment part of the girth machine. Mold mounting section, lower mold mounting section of press equipment and base grate,
It is understood that forces are exerted through the longitudinal and oriented relationships between the base plate and the die, respectively.

These mold parts are assembled with locking screws to form a generally aligned mold center. However, before pressing, they must be closely aligned and fixed together. This is done using an auxiliary device called a resetter. The Nori Center has a pair of upper and lower metal heel attachment parts that have location pins that have exactly the same dimensions and arrangement as the mold attachment part in a QDC press machine, and they are connected to guides and if-stretched parts. and a guide bunsch, allowing for precise guidance and relative interlocking.

The assembly of the punch and the punching grate, and the base grate are formed corresponding to them, and are also loosely tightened in advance with multiple cheek screws through multiple screw holes to form one mold of the nori setter. Mounting mζ (This is set, and the die and pace plate are also loosely tightened and set facing the other mold mounting part G of the precenter.The technique of a skilled worker is used to connect the punch and die. Adjust the matching relationship and bring the two closer together, and when precise matching is obtained, firmly fix by tightening each tightening screw again, and finally precise matching is confirmed. After that, remove both from the presetter, drill through holes in the punch plate, base plate, die and base plate, and drive in dowel pins to complete the mold set with the upper and lower molds completely integrated into each other. The thus completed mold set can be easily and quickly attached to the Q and Do depressing device by any person.

As mentioned above, in QDC molds die set costs are saved because die sets do not have to be provided in individual mold sets. Moreover, the removal of the die set, which occupies half or more of the volume of the mold set by weight, greatly facilitates its handling and also significantly reduces its storage space.

Therefore, a mold set suitable for high-mix, low-volume production in which the mold set is frequently attached and detached is provided.

However, in the case of Q and Do molds, a pair of upper and lower pace plates is required instead of a die saint, and additional auxiliary devices such as agricenters must be installed. The final alignment and integration work of the mold set, which involves re-centering the mold set by 7 or 2 degrees, still requires the skills of skilled workers, and therefore it takes time to provide the molds.
Therefore, the cost was high, and the QDO system was not necessarily satisfactory.

For example, when shearing a thick blank, the sheared edges of the sheared I/Ml may have some "sag" or a rough surface, but these sheared edges will not be finished. In order to do this, open these parts several times and slowly remove them from the front and back.
Alternate scraping is carried out, first, by means of several cutting die saints having generally similar cutting edge patterns that differ in size by the amount of scraping. After the 9 items of these mold sets are completed, the final set (4
Even though I'm hurt, Yu.

It takes as long as three days.

The inventors of the present invention can easily and quickly supply mold sets without relying on the skills of skilled workers, and can also be easily and quickly attached and detached by any person at a press work site. We researched simple molds and their manufacturing methods, and completed a satisfactory simple mold system.

Q. Conventional molds, including CD molds, are used in combination for one pressing operation, and the final mold set must be precisely matched by the skill of an experienced worker. Because they were constrained by the fixed idea that there was no way they could obtain zero-free products (which they should be satisfied with), they took the wrong direction in developing simple molds.

An object of the present invention is to provide a simple mold and a manufacturing method suitable for high-mix, low-volume production that can be applied to various types of fress processing.

Another object of the present invention is to provide a simple mold that can be commonly used for trial production, small-scale production, and transition to mass production, and a method for manufacturing the same.

Still another object of the present invention is to provide an easy-to-use mold that has a small number of parts, can be supplied inexpensively and quickly, is easy to handle, and is convenient for storage, and a method for manufacturing the same. That's true.

A further object of the present invention is that it can be produced without relying on the skill of a skilled worker and that
r that can be easily and quickly attached to and detached from the NOS device.
The purpose of the present invention is to provide a mold that is easy to use when t<1, and a method for manufacturing the same.

Still another object of the present invention is to provide a simple method for dipping a mold that can create a plurality of identical mold sets.

Other objects and advantages of the invention will become apparent from the following description.

This @I invention is a shearing die for handling external shapes, hole punching, feed punching, total punching, etc., a bending die for bending 9-box bending, folding, etc., a relatively shallow drawing die, or the like. The terminology defined below is used to give a common expression to these composite molds.

A general term for mutual arrangement and orientation relationship. used.

Auxiliary hole: Refers to a hole that is formed in various molds and used for various purposes such as connecting molds, supporting separation, etc.

The mold according to the invention is premised on the use of a press device of the same type as the press device for QDO molds. That is, it has a pair of mold holder attachment parts guided so as to be movable relative to each other along one axis mz, which is usually a vertical direction, and each of the attachment parts is provided with at least a number of location pins. It is assumed that a press device is used in which the position and orientation of the location pins of one mounting part and the position and orientation of the location pins of the other mounting part are in a precisely constant arrangement and orientation relationship. It has become.

For convenience of explanation, in the following description, it is assumed that these mounting parts have a pair of location pins whose central axes are aligned in two directions.

Further, in the present invention, when the first type of mold having a standardized cylindrical shank is mounted on the press device, the mold is interposed between the mold and the press device. , a first type of mold holder that uniquely positions it with respect to the press equipment, and a second type of tights mold that is typically plate-shaped and has a standardized rectangular plate surface are attached to the press equipment. When doing this, a second tights mold holder is provided in advance in the press device, which is interposed between the mold and the press device and positions the second tights mold holder with respect to the press device.
It is assumed that these mold holders are used in common for a plurality of different mold sets used for various press processing.

According to the above-mentioned assumption, the first type of mold holder has a pair of location pins formed in a corresponding arrangement and orientation so as to receive the pair of location pins in the mold mounting part of the press machine without any play. a location hole and a predetermined arrangement for the pair of location holes;
a mold positioning hole for receiving and positioning a standardized cylindrical shank of the first tights mold which is oriented and typically has a constant outer diameter; and said mold positioning hole. are formed in a predetermined arrangement and orientation with respect to the pair of location holes at the peripheral edge of the mold to predetermine a pattern specific to the press working part (for example, the cutting edge of a punch) of the first type of mold. Orienting means (for example, a key groove or key) for orienting in a predetermined direction, and a plurality of auxiliary holes having a predetermined arrangement and orientation relationship with respect to the location holes are formed.

The second type of mold holder is similar to the first type of mold holder except for the mold positioning hole and orientation means described above, and includes a pair of location holes and a plurality of auxiliary holes. It is formed in the same way as above. The means for positioning and orienting the second tights mold in the second type of mold holder includes a plurality of screw holes for receiving a plurality of screws and a plurality of dowel pin holes for receiving a plurality of 7-pin pins. and a plurality of mold positioning holes formed in a predetermined arrangement and orientation with respect to the pair of location holes.

Given the presence of a press apparatus and first and second tights mold holders as described above, the mold set of the present invention typically includes at least one mold having a standardized cylindrical shank. It includes a first mold and at least one plate-shaped second mold, typically having a standardized rectangular plate surface.

The mold of the first tights is made from the mold of the mold holder of the first tights 0, based on the coordinates arbitrarily set on the end surface to be mounted on the mold holder of the first type. A typically cylindrical shank that fits into the positioning hole without play, and a side surface of the shank that is formed to correspond to the orientation means formed on the mold boulder of the first type. and an orientation means that cooperates with it (for example, if a key groove is formed in the mold boulder, a key that fits into the key groove) is formed with a precision of 1dIJ, and the opposite On the "end face" 2, a press action part pattern (for example, a cutting edge pattern of a shear punch) having a shape and size suitable for desired press working is provided on the orientation means, based on two-dimensional coordinates arbitrarily set on that surface. It is precisely measured and formed in a predetermined orientation direction.

Thus, the first type of mold has its shank part fitted into the mold positioning hole of the first type of mold holder, and by the cooperative action of the corresponding orientation means, the lus action part of the mold is adjusted. The pattern can be uniquely positioned in a predetermined location and orientation with respect to the pair of location holes of the first mold holder, ie with respect to the pair of location pins of the Luss device.

The second type of mold corresponds to a plurality of mold positioning holes formed in the mold boulder of the second type, including a number of screw holes and dowel pin holes, and also has a different arrangement and orientation. a plurality of formed pairs 1+i, a plurality of mold positioning holes each consisting of a screw hole and a dowel pin hole, a planned arrangement a, an oriented press working part pattern (for example, a cutting edge pattern of a die); is precisely measured and formed using arbitrarily set two-dimensional coordinates on the plate surface. Thus, the first type mold is attached to the plurality of positioning holes and the positioning hole of the first type mold holder using screws and dowel pins, and the mold holder of the freeless device is attached. When mounted on the mounting part, the lus action part pattern can be precisely positioned with respect to the location bin of the brace device n by the relative arrangement and orientation of the positioning hole and the location hole.

ff1J, the basic difference 4 between the QDC system and the present system is as shown below.

/) Q. In the OD system, the punch holder and punch tip, which were mold parts, are combined into one as the first type mold holder in this 1IQ1 system.
Moreover, it can be commonly used in different molds not as a part of a mold but as a part of a free press device.

In the present system, the die holder, which was a part of the mold in the QDC system, is not a part of the mold, but is used as a first type of mold holder, and is used as a part of the Luss device to handle different molds. It was made to be commonly used.

, 7) Punch holders, punch plates, die holders, etc. in QDO systems Parts formed from plate blanks such as IJ collars are ground by precisely polishing two adjacent sides of the blank at right angles to serve as reference surfaces. Alternatively, two small holes are pre-drilled at a fixed interval on the blank plate surface, and these are set in a numerically controlled metal processing device (e.g. wire-cut electrical discharge machining device) to cut various holes. In contrast, in the present system, the various holes are arranged and oriented with respect to specific tangible reference parts on the blank. The arrangement and orientation relationships of various holes shall be defined based on two-dimensional coordinates arbitrarily set in , that is, based on virtual coordinate axes rather than on a tangible reference part.

Due to the above differences, the present system has achieved complete standardization of molds, and requires the skill and skill of skilled workers in all aspects of mold creation and mounting on the 7°less device. This makes it possible to completely eliminate the need for In other words, the difference in /) above is not only due to the fact that two parts of the mold in the QDC system, namely the punch holder and the punch plate, can be omitted from the mold (this effect itself is not important). However, the assembly of the punch plate and punch eliminates the need for skilled technicians by eliminating the need for integration work. After all, the punch had to be precisely inserted at right angles to the punch plate surface. Also, the difference between
The die holder as a part of the mold in the C system,
In the system of this application, the foam is not used as a part of the mold.
In addition to the difference in /) above, by making it a part of the press machine, it reduces interest costs, processing costs, and finishing costs in mold creation, shortens delivery time, and reduces the transportation and storage of molds at the press work site. This is aimed at reducing the cost of pressed products. Furthermore, the difference in 3) above is
Externally, there is no noticeable difference.

However, in the QDC system, it was planned that the matching relationship between die sets would ultimately be performed by the skill of a skilled engineer, so regarding the arrangement of location holes in the punch holder and die holder, The arrangement and orientation of other mold parts were not specified. In the system of the present application, the arrangement and orientation of the press action part patterns in all molds are arbitrarily set on each blank by means of positioning them in the mold holder. By being relatively defined using the dimensional coordinates as a reference, all molds can be created and mounted on a press machine without the intervention of the skills of a skilled engineer.

Its accuracy depends solely on the precision of the machinery and equipment used in mold manufacturing. By standardizing the mold holder as a part of the freeless device, standardization of all general molds has been completely achieved.

The present invention will be explained in more detail below with reference to some specific examples of the present invention illustrated in the accompanying drawings.

FIG. 1 is a cross-sectional view showing a mold set for contour cutting according to the present invention and a part of the mold holder attachment part of a press machine, and FIG. 1a to FIG. It is a figure showing the details of the mold in the specific example shown in 1, and a mold holder for mounting them on a press device. In this specific example, the mold set is shown as a three-piece mold set including an outline punch/as a first mold, an outline die as a second tights mold, and a stripper 3. . The punch/ is attached to the die holder mounting portions O and 7 of the press device via the die holder q of the first tights, and the die is attached via the die holder S of the U-th type, respectively.

Each of the mold holder mounting portions is provided with a pair of location pins, 7/, which are operated from the outside to connect the first and second types of mold holders. Location hole 4/ provided in.

Since this is commonly used in press equipment for Do molds, it will not be described in detail.

There is a mold positioning hole in the mold holder of the first tights.

1st. a is a bottom view of the first type of mold holder q shown in FIG. 1; Although the mold positioning holes q are shown as holes having a circular cross section, they may have an irregular polygonal cross section. When the cross section of the mold positioning hole is an irregular polygon, the key groove is not necessary because the hole itself functions as an orientation means for determining the orientation of the first mold (punch).

However, from the practical point of view, it is desirable to have a circular cross section. Two keys'/M'13 are shown as being positioned 4 at an angle of 00 about the center of the mold locating hole. 1b to 1d show a plan view, a side view, and a side view of the punch shown in FIG. 1. punch/
It has a cylindrical shank // at the proximal end that is attached to the mold holder of the t-th tights, a key /λ along the generatrix on its side, and a threaded hole cut in the center of the end face of the shank. I have 10. A cutting edge/3 pattern of a desired shape is formed on the opposite end. In the specific example shown in the drawings, a flange is provided at an intermediate portion between the base end and the cutting edge, but this is not an essential feature. However, the bottom wall 4.2a (FIG. 1) of the mold positioning holes + and 2 of the mold holder 1 of the first tights 0 has the effect of distributing and reducing the load received during the pressing operation. The cutting edge pattern of the punch// is relatively precise based on the two-dimensional coordinates arbitrarily set on the cutting edge 9161 surface in a predetermined arrangement and orientation regarding the shank// and the key/2. . When the shank // is inserted into the mold positioning hex q2 and the key /2 is fitted into one side of the key groove t13, the cutting edge pattern of the punch will match the mold of the first tights. Uniquely located in one selected arrangement and orientation with respect to the pair of location holes tI/ of the holder, and therefore they are fixed with screws (not shown) through the screws 6qθ formed in the bottom wall. After that, when it is positioned in the press device by the location pins 6/ of the mold holder mounting part B, it is uniquely positioned with respect to the pair of location pins 61.

FIG. 1θ shows a plan view of the mold holder of the first tights. The mold holder 3 of the first tights has a large hole f2 (typically rectangular) that is commonly used for the first mold of all yuzu fruits, and a mold positioning hole 54-3 for the number of bales. auxiliary holes 37 to S9 are provided, all of which are arranged in a predetermined manner with respect to the pair of location holes.
The orientation relationship is precisely defined based on β-dimensional coordinates arbitrarily set on the plate surface of the mold holder.

FIG. 1f shows a plan view of the outline punching tool (first type of mold) 2. As shown in FIG. Daiyu is provided with 2 cutting blades and 9 auxiliary holes 27 to 2q with the desired clearance regarding the cutting edge pattern of the punch, all of which are connected to multiple mold positioning holes. 6 is precisely defined and formed in a predetermined arrangement and orientation relationship based on arbitrarily set β-dimensional coordinates on the plate of the mold.

Further, the plurality of mold positioning holes 2'L-coB are arranged in exactly the same pattern as the plurality of mold positioning holes Stt to S6 in the mold holder S of the first tights.

To attach Daiyu to the first type of mold holder,
For example, screws are inserted into selected holes (for example, two holes, t4t) among the plurality of mold positioning holes Sda to S6 and the corresponding mold positioning holes (for example, two holes, t4t). This is done by driving dowels into a plurality of selected mold positioning holes (for example, two holes 55 and two holes 55) to prevent misalignment between the two surfaces.

Thus, the pattern of the die's cutting edges is defined for a plurality of mold positioning holes 6 to 2, and a plurality of positioning holes 54 in the first type mold holder S corresponding to these positioning holes. −I4 is a pair of location holes, f

The 嫡/g figure shows a plan view of the stripper (second tights mold) 3. The stripper 3 has a vine hole 32 (
-7°resist action part pattern) and a plurality of auxiliary holes 3'l. All of these are arranged in advance with respect to the plurality of positioning holes 33.

6 In the same relation, the shape is precisely defined based on the β-dimensional coordinates arbitrarily set on the plate surface of the IJ collar. The plurality of positioning holes 33 are brocade/
They are formed to correspond to two of the auxiliary water pipes 9 in the type of mold holder. The stripper 3 is positioned and held apart from the first type mold holder via an elastic sleeve 3tl inserted through a screw (not shown). Strypa's Rusu explosive part pattern 3
．． 2 is the first through the positioning IR hole 33 and the auxiliary hole 3q
The arrangement and orientation are determined with respect to the auxiliary water gouge of the type of mold holder, and the arrangement and orientation are determined with respect to the cutting edge pattern of the punch/(first tights mold).

Therefore, when creating the punch/dail and stripper 3 as described above, the arbitrarily determined two-dimensional coordinates do not need to precisely match those shown in the drawings, and the shanks processed on the respective mold blanks, Key.

It is sufficient that the breath action part pattern, the holes of each ridge, etc. are formed in a relatively predetermined arrangement and orientation on each mold. 1st b, 1st f, 1st F! , the outline of the external shape of each mold shown by the overhead line in the figure is ! A case is shown in which the next t-coordinate is taken at a position different from that shown. Against these contours, the shank.

Key, 7') Rest action part pattern, various holes are at the positions and orientations shown by solid lines. However, the mutual arrangement and orientation of these molds on each mold is constant with respect to the set two-dimensional coordinates, and therefore, the molds are attached to the press device via the first and second mold holders. When this happens, each pair of location bins is positioned in unison.

The mold (outline punch) for the first tights is typically made from a cylindrical blank, for example by a reverse electrical discharge machining machine, in a manner similar to that described for making the QDC mold. The difference is that the shank//, key/co, and flange/Il are formed, and the cutting edge pattern/3 has a predetermined arrangement and orientation relationship with respect to the shank// and key/co. All of them are formed based on two-dimensional coordinates arbitrarily set on the end face of the blank. Setting of this two-dimensional coordinate is performed indirectly. In other words, the arrangement and orientation of the guide hole in the guide frame with respect to the guide post insertion hole when mounting the blank on the blank support part of the reverse electrical discharge machining device, and the arrangement of the discharge opening in the discharge electrode with respect to the guide post insertion hole. , is set by the relative relationship with the orientation relationship. Guide holes in these guide frames.

The insertion hole, the insertion hole in the discharge electrode, and the discharge opening are precisely defined and formed based on arbitrarily set two-dimensional coordinates on the plate surface of the plate-shaped blank. To those skilled in the art, no further explanation is deemed necessary. The shank// and the key/2 are formed in a predetermined arrangement and orientation based on two-dimensional coordinates arbitrarily set on one end surface of the blank.

The blank with the shank// and key formed is set in a reverse electrical discharge machining machine with its center axis upside down.
The cutting edges /3 have a predetermined arrangement Ii'L with respect to them.
, are precisely defined and formed on the opposite end surface of the blank based on arbitrarily set two-dimensional coordinates, in an orientation relationship. For example, the reverse electrical discharge machining device U
Position it on the blank support part of the
In this way, a discharge electrode having a discharge opening and a guide post through-hole formed in a relatively desired arrangement and orientation and having a required discharge gap with respect to the desired cutting edge pattern /3 is provided. Process in the same manner as above. Tsubabe/4'
is achieved by making the sum of the axial movement distances of the guide posts of the two discharge electrodes smaller than the axial length of the blank. + is formed. These curved plates and free electrodes can be created using, for example, a wire-cut electrical discharge machining machine, and this can be done by using a second tie 7° mold (as will be understood from the following explanation regarding the creation of the outline die). Good morning.

The mold 2 (outline cutting die) for the #th tights is produced from a blank, typically for forming a rectangular plate surface, in a manner similar to that described for the production of the QDC mold, for example by means of a wire-cut electrical discharge machining machine. Created. The difference is the cutting edge of the die, 22. Multiple mold positioning holes 2'l to 6. O! A number of auxiliary hole cores ~uq are precisely defined and formed in a predetermined arrangement and orientation based on a two-dimensional 1' mark arbitrarily set on the center 1. A small hole is formed in each region of the blank in which each of the holes is to be formed, and two-dimensional coordinates are arbitrarily set on the plate surface by a metal processing device operated by numerical sterilization. The blank with the small hole drilled in it is set on the blank support part of the wire cutting machine, but at this time, the two-dimensional V1
It is not necessary to precisely match the four marks; all that is required is to set the drilled small holes with such precision that they do not deviate from the area where each hole is formed by wire-cut electrical discharge machining htif. Thereafter, each of the small holes is sequentially machined using the wire-cut electrical discharge machining apparatus 1 to precisely machine the mutual arrangement and orientation using the two-dimensional seat ridge newly set on the plate surface as a reference.

In the conventional manufacturing method of QDO molds, holes with a certain number of axes with some play for approximate positioning are formed corresponding to the die and die holder, and a )0 recess notar is used. After aligning the pair of punches, they were fixed with screws, and a through hole was drilled between them, and then a knock pin was driven in.

On the other hand, in the present invention, the planned arrangement of the pair of location bin holes 51 in the second mold holder,
The cutting edge pattern of the die is formed in a predetermined arrangement and orientation with respect to the multiple positioning holes on the die formed in the same pattern as the multiple mold positioning holes formed in the same pattern. By inserting a tightening screw into the hole, tightening it, and driving a dowel pin, it is possible to uniquely position and orient the wire-cut electrical discharge machining device in the press device with an accuracy that depends on the viscosity of the device itself.

The creation of the punch plate 3 (the second type of mold) is completely the same as the creation of the die described above, and the explanation will be omitted.

Multiple positioning holes 33. The plurality of auxiliary holes 3tl are formed in the same arrangement pattern as the plurality of auxiliary holes 7 of the type holder. Since the mold holder is formed in a predetermined arrangement and orientation, a screw rod (not shown) with an elastic sleeve 3'l made of soft plastic, etc. Multiple auxiliary holes 11.9
When mounted on the machine (spear/figure), the hole 3.2 fits into the cutting edge/3 of the punch with a precision that depends on the precision of the electrical discharge machining device itself.

In other words, the outline punching die set shown in the figure is the same as a punch made of only one part machined from a cylindrical block and a die made of only one part machined from a plate blank. It consists of only three parts: IJ collar 3, and they can be used for mold holders of type 3, 3, and λ without the need for equivalent finishing alignment work.
It can be easily fixed by someone using the tightening screw and knock bottle on the left side.

In addition, in the figure, the metal 1 to reholder of type ``spear'' is shown as an integral piece, but in reality, it is two pieces at the level of the bottom of the mold positioning hole shown by the dotted line. By using stamped parts, each part can be made in a manner similar to a j-λ type mold.

Figure A-2 shows the outer shape cut out using the mold set shown in Figure A-2.
A punching die set for punching a pair of small holes in the planned positions of a rectangular product with rounded corners is attached to the press machine. /It is a cross-sectional view similar to the figure. The mold set shown here is a hole punch/(spear/ type mold), hole punch die, 2 (1-, 20 type molds)
, stripper 3C-A12 type mold), and guide plate, ! It is a four-piece set with rl a, 20 types of gold m).

As shown by the dotted line in the bottom view of Figure 2a, the punch// has a shank// having exactly the same shape and dimensions as the punch/ of the specific example shown in the fang/ figure, and the key 7.2 is attached to the proximal end surface of the cylindrical blank. It is precisely defined and formed based on the a-dimensional coordinates arbitrarily set above.

The punch cutting edge /3 pattern shown as two thin protrusions to form a pair of small holes is the shank //,
The predetermined arrangement and orientation of key/2 are relatively accurately defined with reference to the a-dimensional coordinates arbitrarily set on the opposite cutting edge end face. Therefore, this hole punch is attached to the mold holder attachment part B of the press machine via the mold holder of the type 2 shown in the figure. .

The plan view of the punching die is shown in Figure 2b, which shows a plurality of mold positioning holes 2q to 2o, double-hole auxiliary holes, and 27 to 2.
9 is a mold positioning hole 5 hiro of a fan type mold holder provided as a part of a press device (I-/E figure)
The pattern of the die cutting edge 22, which is formed in the same arrangement and orientation as the S B and the auxiliary holes 57 to 7, and has the desired clearance with respect to the pattern of the cutting edge 3 of the punch, is that the pattern of the die cutting edge 22 is -, 2B, auxiliary holes, 27 to 27 are formed in a predetermined arrangement and orientation. The mutual arrangement and orientation of the kneads 5 are not based on a specific 4j-shaped portion on the plate surface of the die, but are formed based on a-dimensional coordinates arbitrarily set on the plate surface. There is.

Attachment to the die holder 5 (see figure 2/e) of the die 〇 λ type is carried out using, for example, two tightening screws and two knock pins. Tighten the two positioning holes 1, 2, or two positioning holes 2 and 2 of the die in the two positioning holes S and 2 of the die holder, and It is sufficient to simply drive two dowel pins into two positioning holes 2 and two positioning holes SS that are aligned with each other. The left side of the die holder with the die attached is uniquely attached to the die holder attachment part 7 of the press device.

When installing the die holder q of the punch / and 3. The two positioning holes 5II of the type mold holder are aligned and screwed together, and the number of dowel pins are driven into the positioning holes selected from the remaining metal, thereby arranging the die-〇 cutting blade pattern in a corresponding manner.

A die holder S of the J-J type can be mounted with the die in the orientation. For this purpose, the plurality of positioning holes and the plurality of auxiliary holes in the gouer and spear-type mold holders are shown as being arranged correspondingly on the sides of a square. In the mold holder of type 10/
For example, if the two gear loads +'3 are at an angle of 40° +Il
This means that the multiple positioning holes and multiple auxiliary holes of the type 2 mold holder should be provided at an angle of 0 o 0 on the circumference. The figure shows a stripper 3 (types of metal 1 to 1) used in combination with the punch shown in Figure 2a. Positioning hole 33. The auxiliary holes 3.2 are exactly the same as those explained with reference to FIG. 172, and the press working part pattern 3.2 with the desired clearance with respect to the punch cutting edge/3 pattern is inserted into their positioning holes 33.2. The auxiliary hole 311t is precisely formed with a predetermined arrangement orientation based on arbitrarily set two-dimensional coordinates on the plate surface of the IJ collar 3.

Thus, when it is attached to the auxiliary hole dove on the mold holder q of type 3// using the screw (not shown) and the elastic sleeve 3/I of the original, The press action portion patterns 32 are fitted and supported by the cutting edge pattern of the punch.

7 to g9 are formed in the same pattern as the positioning holes and auxiliary holes in the die holder S and the die, and the guide surface g2 has a predetermined arrangement, The orientation is precisely defined with reference to arbitrarily set λ-dimensional coordinates on the plate surface.

In this specific example, the guide surface g2 is shown as a guide plate for positioning the product formed by the mold set shown in Figures /d, f, and g on the die shown in Figure 125. The guide plate g, the Daiyu type and the Oni type mold holder left can be easily connected using tightening screws and dowel pins without requiring the same skill. The mold holder S of the 31 type in which the guide plate g and the die are combined can be easily mounted on the mold holder mounting part 7 of the press machine without requiring equivalent skills.

Gui, 2. The manufacturing method of the four-piece mold set including the stripper 3 and the guide plate is exactly the same as that described with respect to Figures 2 and 7, 9o/b to d2o/f, and 3□1g.

Figure 3-3 shows a mold set that can be used as a total puncher to create a product created by the outline punching and hole punching mold set shown in Figure 2 in one press operation. .

The outline punch / is almost the same as that shown in Figures /b-d, and the difference is that the cutting edge pattern /3' of the hole punch /' (1 blade of the punch in Figure 1A2a) pattern/
3) is formed on the punch surface with the desired clearance, and the screw hole 10 shown in J-/b 1 is not formed. The type of mold holder for attaching the punching corbel to the press equipment is
It has a similar structure to that explained in connection with the figure, but the hole 7 is for dropping the punching chips that fall from the cutting edge of the hole puncher.
The only difference is that 0' is formed.

The hole punch /' and the spear-type mold holder holding it are exactly the same as those described with reference to FIG. 312.
