More specifically, the antenna coil in the reader Z writer for reading and writing data of the ID tag provided on the upper part of the punch die And a mold provided on a striker which is vertically movable on a punch press, a mold thereof, a method of attaching the antenna coil to the strip force, and various data of the mold. Read and write related tag holders. Scenic thunder

Conventionally, the management of nonch dies, which are conventionally used by attaching and detaching and replacing punch punches, and In order to improve the work efficiency of NC tape making by associating the station number in the punch press with the punch die mounted on the station, A technology has been developed in which a parchment is provided in a mold and a sensor for reading the bar code is provided in a non-press manner. This is the Japanese Patent No. 2 It is disclosed in Japanese Patent Publication No. 5070722 (1st reference).

An ID tag storing die information is provided at the top of the punch die, and an antenna coil in a reader / writer for reading and writing data to the ID tag is provided. A configuration has also been developed in which the striker is equipped with a non-pressurized vertical movement. This is, for example, the official gazette of Japanese Patent Publication No. 4-133420 (No. 2) and the Japanese Utility Model Registration No. 25 339 9 25 (No. 3). Is disclosed.

In the configuration described in the first document, there is a problem that if the bar code provided on the punch die becomes dirty, it becomes difficult to read the bar code using a sensor.

As described in the above-mentioned first and second documents, an ID tag is provided on an upper part of a punch die, and a antenna force of a reader Z writer is provided for a striking force in a punch press. Although the influence of dirt on the punch die is small, the above-mentioned strip force and the punch die are made of metal. Therefore, when the antenna coil and the ID tag are embedded in the metal, the surrounding metal is removed. If the communication distance is shortened due to the influence of the ID tag, there is a problem in communication. If the back of the ID tag is in close contact with metal, communication may not be possible.

Therefore, in the configurations described in the second and third documents, no. In order to read the data of the ID tag provided on the upper part of the punch die, the punch die and the striker are positioned so that they are in a positional relationship facing up and down. It is necessary to lower the strike force to a position where communication is possible (until the distance between the punch die and the strike force is about 2 to 4 mm), so that the ID tag data can be read and read. Writing takes time and there is a problem in improving efficiency.

Furthermore, when the strike force presses the punch mold by the striking force, the antenna coil may fall off the striker sometimes. Ray ヽ There is a problem.

In addition, the conventional punch press is equipped with a working fluid supply device to lubricate and cool the punch die, and to prevent the clogging after punching, etc. A punch press has been developed that has a hole for supplying oil to the oil mold supply hole and a hole for guiding oil oil to the tip end side. I have.

In the conventional punch press described above, when the punching die is pressed by the vertically movable striking force, the punch press is made from the oil mist supply hole provided for the striking force. Since the oil mist is blown out and supplied to the introduction hole provided in the mold, the lubrication and cooling of the punch mold are effectively performed, and the work is performed on the cast after the punching process. It is effective and useful for prevention.

However, conventionally, when a working fluid such as an oil mist is supplied from a pressure system such as a pump to a punch die, a constant discharge amount is required regardless of the diameter size of the punch die. It supplies oil mist etc. in this case, If the discharge rate of the working fluid is set to a constant value corresponding to the small-diameter punch die, the large-diameter punch die tends to run out of working fluid, so the large-diameter punch Generally, the discharge amount is set to be constant according to the mold.

In other words, in the above-described technology, a large amount of working fluid is always discharged in correspondence with a large-diameter punch die, and in the case of a small-diameter punch die, an excessive amount of oil is required. In the surrounding area, and the spray may scatter around. There was a problem that it was necessary to remove the oil mist adhering to the work more than necessary.

Therefore, it is desired to supply an appropriate amount of working fluid such as a girm mist in accordance with the size of the nonch, and the oil mist is required in accordance with the size of the punch die. In order to control the amount of working fluid such as ト to an appropriate amount, it is necessary to know the diameter of the punch die that is indexed and positioned relatively below the striker.

On the other hand, in order to facilitate the management of punch dies that are conventionally mounted on punch presses, punches with ID tags that can read and write various data related to punch dies are available. Molds are being developed. This is disclosed in, for example, Japanese Patent Application Laid-Open No. 6-79332 (No. 4) of the above-mentioned Third Document and Japanese Patent Publication.

Therefore, when the punch die is disassembled and stored by grinding due to the wear of the blade of the nonch body in the punch die, etc., the punch body and the punch head are in a separate state. After assembly, the consistency between the punch body and the ID chip may not be ensured.

Also, if the ID chip is replaced when replacing the nonch body with the punch die, the work of removing the ID chip from the punch head is troublesome and may damage the ID chip. There are problems such as.

Furthermore, in the configuration where the ID chip is embedded and fixed in the hole formed on the top surface of the nonch head, the communication distance with the reader / writer is reduced due to the influence of the surrounding metal. There is a problem that it is easy to handle.

Hereinafter, the present invention will be described in detail with reference to the drawings. Referring to FIG. 8, according to an embodiment of the present invention. The punch 1 is provided with a punch die P and a die D for pressing a plate-shaped workpiece W, and also has a pressurizing press for the punch die P. It is equipped with a lie force of 3 that can move up and down freely.

The punch die P and the die die D are mounted on a punch holder 5 and a die holder 7 in a detachable and replaceable manner, similarly to a general punch press.

The punch holder 5 and the die holder 7 are, for example, .

In a 15-turret nonch press, the rotatable upper and lower turrets correspond to the plurality of punch dies P and die D supported by the punch holder 5 and the die holder 7, respectively. It is indexed to a position below the striking force 3 and provided for positioning. The nonch press has a stylus force 3 that can move up and down with respect to the upper and lower nonch holders 5 and the die holder 7. There is also a punch press that has its own configuration by indexing it to the position above the punch die P of its own.

In the punch press 1, the relative indexing and positioning of the punch die P and the die D to the position corresponding to the striker 3 and the machining position (the position corresponding to the striker 3) are performed. The operation of the punchless 1 such as the relative positioning of the workpiece W in the X and Y directions and the vertical movement of the striking force 3 is the same as the normal operation. Like the punch press, the punch press 1 is controlled by the NC device 9, and the punch press 1 will not be described in detail.

The striker 3 is connected to an introduction hole (not shown) provided in the nonch mold P at the time of pressing the punch mold P to eject and supply a working fluid such as an oil mist. A supply port 11 is provided, and a working fluid supply device is connected to the fluid supply port 11.

That is, the connection circuit 15 that connects the fluid supply port 11 and the pressure source 13 is connected to and disconnected from the connection circuit 15. An appropriate on-off valve 17 is provided for the existing solenoid valve. Further, the connection circuit 15 is provided with a negative pressure generator 19 that generates a negative pressure and sucks oil from the oil tank T when connected by opening the on-off valve 17. The connection circuit 21 connecting the negative pressure generator 19 and the oil tank is connected to the connection circuit 21 and the connection circuit 21 is cut off as appropriate for the solenoid pulp that is present. Open / close valve 23 is disposed. The oil tank T is connected to a branch 15 A for pressurizing the oil tank T.

The opening and closing of the on-off valves 17 and 23 is controlled by, for example, a pulp control device 25 as an air-pro device. In order to input various data and the like of the punch die P to be pressed by the striking force 3 to the pulp control device 25, The mold specification data indicating that the punch mold P is an air blown notch or a standard punch having an introduction hole, the mold size such as diameter size data, data on the working fluid supply amount, and the like. The tag 27 stores die type data such as punching dies, molding, tapping, and slotting, die material data, and purchase history data. -Identification (hereinafter referred to as “ID tag”).

On the other hand, the slicer 3 has a read area for reading the data recorded in the ID tag 27 and writing data for the ID tag 27. D / Writer 29 Tenacoil 31 is provided.

Here, the mounting method of the above-mentioned antenna coil 31 constituting the main part of the embodiment of the present invention and the striking force 3 to which the antenna coil 31 is mounted will be described in detail. I will explain.

Referring to FIG. 1, an insertion hole 33 into which the antenna coil 31 can be inserted is located substantially concentrically with the fluid supply port 11 on the lower end surface side of the striker 3. A large-diameter hole 35 having a diameter larger than that of the inlet hole 33 is provided above the inlet hole 33. Accordingly, between the insertion hole 33 and the large-diameter hole 35, for example, a step portion 37 is formed as a locking portion for preventing the antenna coil 31 from coming off. The diameter of the insertion hole 33 is set so that a gap G is formed between the inner peripheral surface of the insertion hole 33 and the outer peripheral surface of the antenna coil 31. It was formed slightly larger than the outer diameter of 1.

The antenna coil 31 is inserted into the insertion hole 33 so that the lower end of the antenna coil 31 is substantially at the same height as the lower surface of the striking force 3, and the antenna coil 31 is inserted into the antenna coil 31. A cylindrical magnetic body 39 having substantially the same length as or a longer length than the antenna coil 31 is inserted into the hole 31. Further, a resin pipe 41 communicating with the fluid supply port 11 is inserted into the inner periphery of the magnetic body 39. Also, for example, a resin 43 for molding, as an insulator, is pressed into the large-diameter hole 35 from the gap G between the outer peripheral surface of the antenna coil 31 and the inner peripheral surface of the insertion hole 33. As a result, a large diameter portion 4 5 is formed. The part 45 and the antenna coil 31 are integrated. The antenna coil 31 is integrated with the strip force 3 by the large diameter hole 35 and the resin 43 filled in the gap G, and the antenna coil 31 is integrated with the strip force. They are held together in a state that is consistent from 3 onwards.

According to the above configuration, the outer circumference of the antenna coil 31 is molded with the resin 43 so that the metal stripping force 3 does not contact the antenna coil 31. Since the antenna coil is fixed and held, there is no danger of leakage of the magnetic flux of the antenna coil 31 or the like. Further, since the influence of the metal of the striker 3 is avoided, the magnetic flux, which is a radio signal from the antenna coil 31, projects relatively large downward from the lower surface of the antenna coil 31. Therefore, a good magnetic flux form is secured. Further, the antenna coil 31 is integrated with the resin 43, and a large-diameter portion 45 as an engaging portion that engages with the step portion 37 is formed in the effect 43. However, the large diameter portion 45 and the step portion 37 are prevented from falling off, and the punch die 'P falls off due to an impact when the punch P is pressed. There is no such thing.

· Further, by providing the cylindrical magnetic body 39 having the property of amorphous with high magnetic permeability in the antenna coil 31, the magnetic flux is reduced by the magnetic material 39. Since it is easy to pass through the inside, the influence of the surrounding metal is reduced, and the magnetic flux density is increased, the magnetic flux of the antenna coil 31 moves downward from the lower surface of the striker 3 The density of the magnetic flux protruding larger than Ri, a ID tag 2 7 A Ntenakoi Le and also chain interlinkage that flux number that Many Do of a having a A Ntenakoi Le ³ 1 and ID tag 2 7 have relatively large rather distant By the way, the presence of the amorphous material of the magnetic material 39 and the magnetic flux density of the antenna coil 31 are small, but the presence of the magnetic material 39 Since the magnetic flux density increases, the reliability of data communication (read / write) improves.

Referring also to FIG. 2, when the antenna coil 31 is mounted and fixed in the insertion hole 33 of the striker 3, a centering jig 47 is used. The centering jig 47 includes a positioning shaft portion 49 that can be inserted into the fluid supply port 11 and a butting reference surface 5 for abutting against the lower end surface of the striker 3. 1, a coil abutting portion 53 for abutting the antenna coil 31, and a gap G between an outer peripheral surface of the antenna coil 31 and an inner peripheral surface of the insertion hole 33 for molding. It is provided with an introduction path 57 having an inlet 55 for press-fitting the resin 43 and a resin supply port 59 for supplying the resin 43 into the introduction path 57. .

Explaining the procedure for mounting the antenna coil 31, the positioning shaft 49 of the centering jig 47 has a resin pipe 41, and a cylindrical magnetic material on the outside. The antenna coil 31 is inserted so that it overlaps with the outside in the radial direction. It is applied. This state Then, the antenna coil 3.1 is inserted into the insertion hole 33, the tip of the positioning shaft part 49 is inserted into the fluid supply port 11, and the butting reference surface 51 is stripped. By being abutted against the lower end surface of the force 3, the antenna coil 31 is centered and positioned with respect to the insertion hole 33. Then, the inlet 55 of the introduction path 57 is located in the gap G between the antenna coil 31 and the inlet 33.

Next, when the molding resin 43 is supplied from the resin supply port 59 to the introduction path 57 as indicated by the arrow in FIG. 2, the resin 43 is connected to the introduction path 57. After passing through, the injection port 55 is pressed into the large-diameter hole 35 through the gap G. Accordingly, when the outer periphery of the antenna coil 31 is molded with the resin 43, the antenna coil 31 and the like are integrated with the stripping force 3 with the resin 43. Then, the centering jig 47 is used for the positioning shaft part 49 force S-knife 41 force, pull-out force, and the antenna coil 31 is attached. finish .

As described above, in a state where the resin 43 is molded and the antenna coil 31 and the like and the stripping force 3 are integrated, the antenna coil 31 is made of an insulator (resin 43). Thus, it is insulated from Striker 3 and fixed integrally.

Referring to FIG. 3, the structure of a striking force 3 to which an antenna coil 31 of another embodiment is mounted will be described using the same reference numerals for the same members as in FIG. When mounting the antenna coil 31, the centering jig 47 of the above-described embodiment is used. An insertion hole 33 and a large-diameter hole 35 similar to those in the above-described embodiment are provided on the lower end surface side of the strip force 3. In this embodiment, a ferrite cylindrical magnetic case 63 having an inner flange portion 61 at the lower end is provided outside the antenna coil 31 having the above-described configuration. The other configuration is the same as the configuration described above. The magnetic case 63 is kept insulated from the striation force 3 by the resin 43.

According to the above configuration, the magnetic material is located inside and outside the antenna coil 31, and the magnetic flux, which is a radio signal from the antenna coil 31, passes through the inside and outside magnetic materials. In other words, the effect of the metal of the strike force 3 on the antenna coil 31 can be reliably avoided, and the magnetic flux density of the magnetic flux that goes out from the lower surface of the strike force 3 to the outside becomes larger, thereby reducing the communication distance. It can be made larger.

Referring again to FIG. 8, the data signal read by the reader / writer 29 is input to the valve controller 25. The valve control device 25 determines whether the diameter of the punch die P belongs to large, medium, or small based on the input data signal, and has an introduction hole. It is determined that the punch is not a normal punch, and the opening and closing of the on-off valves 17 and 23 is controlled.

Therefore, the valve control device 25 is provided with a discriminating means 65 for discriminating the punch die P. The discriminating means 65 has an introduction hole according to the data signal. Whether it is a normal punch die, whether it is an air blow punch with an introduction hole and a small diameter, or whether it is an air blow punch with a medium diameter, or an air blow punch with a large diameter It is to determine whether or not.

When the discriminating means 65 discriminates the punch die P from a normal punch die, the on-off valves 17 and 23 are kept closed, and normal press working is performed. Be done. Then, when the punch die P is an air blow punch and its diameter is determined by the determination means 65, the on-off valve 17 is controlled to open, and the determined punch is determined. The open / close time of the on-off valve 23 is calculated according to the diameter of the mold P.

That is, in this embodiment, the data table 67 that stores (stores) the relationship between the punch size and the opening / closing time is searched, and the opening / closing time corresponding to the determined punch diameter is obtained. The open / close time of the open / close valves 17 and 23 is controlled by the open / close time control unit 69 based on the searched open / close time. The opening / closing time of the on-off valve 23 gradually becomes shorter in accordance with the large, medium and small diameters of the punch dies D and punch dies. A large amount of working fluid is supplied to P, and a small amount of working fluid is supplied to medium-sized and small-diameter punch dies P corresponding to the medium-diameter punch dies P. become.

In the above configuration, the punch press 1 operates under the control of the NC device 9, and the appropriate punch metal is set at the position of the strike force 3. When the die P and the die D are relatively indexed and positioned, the data of the ID tag 27 provided for the punch D is read / written via the antenna coil 31. It is read by 29 and input to the valve controller 25. Then, the discriminating means 65 determines whether the punch die P is a normal punch die or not, and if the punch die P is an air blow punch, whether the diameter belongs to a large, medium, or small diameter. .

Note that when the punch die P without the ID tag 27 is relatively indexed and positioned below the striker 3, the reader / writer 29 can read the data. In this case, there is no input of a data signal in this case, and it is determined that the punch die is a normal punch die. In the case of a punch die having an ID tag, the type of the punch die is determined based on the presence or absence of data indicating that the punch die is an air blow punch.

The data table 67 is searched based on the discrimination result of the discriminating means 65, and an opening / closing time suitable for the diameter of the punch die P located below the striking force 3 is obtained.

When the striker 3 presses the punch die P, the opening / closing time control section 69 controls the opening / closing time of the opening / closing valve 23 based on the searched opening / closing time. The amount of working fluid suitable for the diameter of the mold P is supplied.

That is, when it is determined that the punch die P is an air blow punch, the on-off valve 17 is opened to open the pressure source 13. These airs are supplied to the fluid supply port 11 having the strip force 3. When the air is supplied in this manner, a negative pressure is generated in the negative pressure generator 19, and since the oil tank T is pressurized, when the on-off valve 23 is opened, The oil from the oil tank T is sucked, and is ejected and supplied as an oil mist from the fluid supply port 11 to the introduction hole of the punch die P.

Therefore, an appropriate amount of oil mist suitable for the diameter of the nonch mold P can be supplied without excess or deficiency.

In the above description, the description has been given of controlling the supply amount of the working fluid by controlling the opening / closing time of the on-off valve 23, but as shown by the imaginary line in FIG. Multiple on-off valves 23 A, 23 B with different control flow rates and / or control pressures are connected in parallel, and appropriate on-off valves 23, 23 for large, medium, and small punch sizes It is also possible to adopt a configuration in which A and 23B are selected. In this case, it is possible to adopt a configuration that is selected individually or a configuration in which a plurality of on-off valves are combined and selected at the same time. With two on-off valves corresponding to one punch, large, medium and small punch diameters can be handled. ·

In the above description, the case of the diameter size was described as the data on the supply amount of the working fluid. However, the data of the supply amount itself may be stored in the ID tag 27 in advance. Furthermore, as mentioned above, ID tag 27 Read and write and store data such as mold specifications such as air blow punch or standard punch, mold size such as diameter size data, mold type, mold material, purchase history, and recognize these data. In addition to the execution of the air blow function, it is also possible to manage the frequency of use of the mold and to determine whether the mold to be used is accepted or rejected by checking the match with the program.
