[0009]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an apparatus for manufacturing a laminated rubber from a laminate S having upper and lower overhanging flange plates 3 (hereinafter, referred to as flange plates 3) by utilizing a dielectric heating method.

In this manufacturing apparatus, as shown in FIG. 2, a laminate S is housed in an inner space K of a dielectric heating mold SK formed by upper and lower dies A1, A2, an annular frame mold A3 and a core A4. Let
As shown in FIG. 1, the upper and lower dies A1, A2 approach by a press while applying a high frequency voltage generated by the high frequency oscillator 8 between the upper and lower dies A1, A2 via the parallel electrode plates P1, P2. By applying pressure in the direction, pressure is applied to the laminate S.

Hereinafter, a main configuration and the like employed in the laminated rubber manufacturing apparatus will be described in detail. “About the laminated body S” As shown in FIG.
A circular raw rubber plate 1 having holes 10 and a steel plate 2 having holes 20 (corresponding to the conductive metal plate described in the section of the means for solving the problem) are alternately laminated, and A flange plate 3 having a hole 30 is arranged. Note that an adhesive layer (for example, a combination of a phenol-based polymer and a chlorine-based polymer) may be interposed between the raw rubber plate 1 and the steel plate 2 and between the raw rubber plate 1 and the flange plate 3. preferable.

Here, specific dimensions of the raw rubber plate 1, the steel plate 2, and the flange plate 3 are as follows.

(Rubber plate 1) Diameter: 520 mm, thickness: 6 mm, hole diameter: 90 mm (Steel plate 2) Diameter: 500 mm, thickness: 3 mm, hole diameter: 90 mm (Flange plate 3) Diameter: 700 mm, thickness: 25 mm, hole diameter: 90 mm "Regarding the high-frequency oscillator 8" The high-frequency oscillator 8 is constituted by a known circuit. The frequency used for high-frequency dielectric heating is generally in the range of 4 to 80 MHz,
It can be used within the range of 1 to 300 MHz. "About the upper and lower dies A1, A2" The upper and lower dies A1, A2 are made of circular steel plates, and have a slightly larger diameter than the assembled frame dies A3. The lower surface of the upper die A1 and the upper surface of the lower die A2 are provided with recesses 11 near the outer periphery, in which the upper and lower ends of the frame die A3 are loosely fitted. It should be noted that a protrusion may be used instead of the recess 11, and in this case, a recess in which the protrusion is loosely fitted may be provided at the upper and lower ends of the frame A3. “About the frame A3 and the core A4” As a material of the frame A3 and the core A4, a loss coefficient (dielectric constant × dielectric loss tangent) is 0.3 or less, preferably 0.15 or less [measurement method: JIS K6
911, test conditions: temperature 20 ± 2 ° C, relative humidity 65 ± 5
%, Frequency for measurement: 1 MHz], and a composite material such as an epoxy resin, an ester resin, and respective glass fibers is used. The reason why the loss coefficient is set to 0.3 or less as described above is that, when the loss factor is further increased, the internal heat generation of the frame mold A3 and the core A4 is much larger than that of the raw rubber plate 1, and the medium A3 and the medium This is because the temperature around the core A4 locally rises, which makes it impossible to heat the raw rubber plate 1 uniformly. On the other hand, the epoxy resin and the ester resin are used like the phenol resin during the curing reaction. This is because there is no need to remove generated by-products, and there is no need to mold with high pressure in a mold.

As shown in FIGS. 1, 2 and 4, the frame type A3 has an outer frame A31 having a circular inner circumference and an outer circumference slightly smaller than the inner diameter of the outer frame A31. An inner frame A32 which is formed in a circular shape and surrounds the stacking surface of the stacked body S in a state of being fitted in and detachable from the outer frame A31.

The outer frame body A31 has high-frequency insulation properties, compressive strength properties, compressive creep properties, heat resistance, water absorption, dimensional stability,
In consideration of dimensional accuracy, large size adaptability, cost, etc. (see FIG. 1), the whole made of a heat-resistant epoxy resin or an ester resin and a glass fiber or an aramid fiber is a non-conductive composite, and is a filament winding molding method. Fiber reinforced resin (hereinafter referred to as FRP) formed integrally by a laminated pipe molding method, a hand lay-up molding method or a spray-up molding method.
) Is used. When this configuration is adopted, a large product (having a diameter of 400 to 2
000 mm) can be manufactured.

[0017]

[Table 1]

Further, since the outer frame body A31 is of an integral type, it is possible to obtain a pressure resistance in the circumferential direction. Further, since the outer frame body A31 is made of a composite such as glass fiber, the strength and heat resistance are improved, and linear expansion is achieved. The effect of reducing the coefficient (reducing the linear expansion coefficient to the same level as the metal constituting the upper and lower molds A1 and A2: see Table 2) can also be obtained. In particular, the above-described reduction of the linear expansion coefficient is caused by the upper and lower molds A1 and A2.
The gap formed at the time of fitting the peripheral wall surface of the concave portion 11 and the peripheral surface of the upper and lower ends of the frame type A3 has an effect of not changing much due to a temperature change, and thereby, even if there is a temperature difference, The assembly of the mold and the removal of the product can be easily performed.

[0019]

[Table 2]

The laminated tube forming the outer frame body A31 is machined, and in particular, the upper and lower end surfaces of the outer frame body A31 (corresponding to the protrusions described in the section of means for solving the problems). And preferably parallel).
Is formed so as to contact almost the entire surface with the bottom surface of.
Because, when the gap is formed between the upper and lower end surfaces of the outer frame body A31 and the bottom surface of the concave portion 11,
This is because when the pressure from the press during molding decreases, the rubber material enters the gap and adversely affects the height dimension of the product.

The filament winding molding method and the laminating tube molding method, which have been selected as the methods for manufacturing the large-sized FRP laminated tube selected this time, use a fibrous reinforcing material such as glass fiber or glass cloth impregnated with resin in a mandrel having an appropriate diameter. This is a method in which a laminated tube is produced by winding the resin under tension and then curing the resin by heating. Laminated pipes made by the laminated pipe molding method are classified into two types (laminated pipes formed by winding under pressure) of thermosetting resin laminated pipes (JIS K6914), and require special molds. Instead, the inner diameter is determined only by changing the diameter of the mandrel, so that it is easy to cope with a large diameter, and a large-scale laminated tube satisfying required specifications can be manufactured relatively inexpensively. In addition,
The fibrous reinforcement used for the FRP laminated pipe is JIS R3
411 (glass chopped strand mat), JIS
R3412 (glass roving), JIS R341
3 (glass), JIS R3414 (glass cloth), JIS R3415 (glass tape), JIS
R3416 (processed glass cloth) and JIS R341
No. 7 (glass roving cloth) and alkali-free ones as defined above.

As shown in FIGS. 1 and 2, the inner frame A32 is set to be smaller than the dimension of the outer frame A31 in the stacking direction of the stacked body S by at least the total thickness of the upper and lower flange plates 3, and is also shown in FIG. As shown in the drawing, the stacked body S is composed of four blocks B so as to be able to be divided into four in a direction perpendicular to the stacking direction. In addition, the inner frame body A32 has at least upper and lower flange plates 3 than the dimension of the outer frame body A31 in the stacking direction of the stacked body S.
Are set smaller by the total thickness of the upper die A1 and the upper surface of the inner frame A32, and between the upper surface of the lower die A2 and the lower surface of the inner frame A32 in which the flange plate 3 is accommodated. In order to make

The inner frame A32 is basically made by impregnating a glass cloth with a heat-resistant epoxy resin or an ester resin in consideration of high-frequency insulation properties, compressive strength characteristics and the like, like the outer frame A31. It is formed by heating and pressing in a state in which a large number of products are stacked. Inner frame A32 selected this time
The method of manufacturing the block B is to machine a resin plate formed by heating and pressurizing a glass cloth impregnated with a heat-resistant epoxy resin in a state of laminating the glass cloth into an arc shape. Are bonded in such a manner that a plurality of sheets are laminated.

On the other hand, the above-mentioned outer frame A31 and inner frame A32
Is machined and subjected to processing required as a molding die for laminated rubber (such as a hole for rubber removal during molding). Furthermore, since the fibrous reinforcement such as glass fiber may be exposed on the machined surface, it is possible to coat a resin material thereon or to perform a release agent treatment.

The core A4 is formed by a method equivalent to the above-mentioned molding method. "About the parallel electrode plates P1 and P2" The parallel electrode plates P1 and P2 are made of a steel plate having a slightly larger area than the upper and lower dies A1 and A2, and function as a hot plate by providing heating means (not shown). It is. In addition, as a heating means, for example, a heated fluid such as steam or oil is flowed into the parallel electrode plates P1 and P2, or the parallel electrode plates P1 and P2 are heated.
A configuration in which a heat wire is embedded in P2 can be adopted.
Here, the heating means is provided in this manner,
This is because the heat radiation from A1 and A2 is prevented so that there is no temperature difference between the outside and the inside of the laminate S. "Function and the like by this dielectric heating device" As shown in FIG. 1, the laminate S is positioned between the parallel electrode plates P1 and P2, and the high-frequency voltage generated by the high-frequency oscillator 8 is applied to the parallel electrode plates P1 and P2. When they are added to each other, the steel plates 2 laminated at substantially equal intervals serve as intermediate electrode plates, and all the raw rubber plates 1 are heated simultaneously regardless of the inner and outer parts, and provided on the parallel electrode plates P1, P2. In addition to the function of the heating means, the laminate S is heated almost uniformly to the vulcanization temperature in a short time. In addition, by stopping the oscillator,
It is also possible to control the temperature at an arbitrary temperature without causing overheating, and this state can be maintained for a long time by supplementing the heat with external heating. This is clear from FIG. That is, according to this method, the heating can be performed much faster than in the conventional method, and the temperatures of the inside and outside can be approached.

The following is clear from the above description and FIG. Whereas the conventional method using only the external heating method takes 15 hours or more to produce a laminated rubber, the production method according to the embodiment of the present invention can complete the laminated rubber in a short time of about 5 hours. In the conventional production method using only the external heating method, the vulcanization proceeds in a state where the temperature difference between the inside and outside is large, so that the physical properties thereof are inferior. Since the vulcanization proceeds with no difference, its physical properties are excellent. "About the press machine" As shown in FIG.
A base 40, and a hydraulic cylinder 41 provided above the base 40
And a pressing plate 42 attached to the output shaft end of the hydraulic cylinder 41, and a rod-shaped pressing portion 43 made of a non-conductive member and fixed down to the pressing plate 42. In this embodiment, the above-described parallel electrode plate P1 is attached to the lower end of the rod-shaped pressing portion 43, and the parallel electrode plate P2 is attached to the upper surface of the base 40. (Other Embodiments) If the block B constituting the inner frame A32 shown in Fig. 5 is used instead of the inner frame A32 of the above embodiment, a square laminated rubber can be easily manufactured. In addition, although the inner frame A32 of the said embodiment is comprised from four blocks B, it is not limited to this, The inner frame A
The same effect can be obtained as long as 32 is composed of two or more blocks B. In the above embodiment, the dielectric heating of the raw rubber plate 1 of each layer is performed by disposing the laminate S between the parallel electrode plates P1 and P2 in such a manner that the raw rubber plate 1 and the steel plate 2 are parallel to the parallel electrode plates P1 and P2. This is performed by applying a high-frequency voltage between the parallel electrode plates P1 and P2. Instead of this configuration, a high-frequency voltage is applied between the upper and lower dies A1 and A2 which are parallel to the raw rubber plate 1 and the steel plate 2. The raw rubber plate 1 may be dielectrically heated by applying a voltage. In this case, the upper and lower dies A1 and A2 are provided with heating means to function as a hot plate.

Further, in place of the above configuration, the parallel electrode plates P1,
A configuration in which a hot plate is brought into contact with P2 so that heat transfer is possible,
A configuration may be adopted in which a hot plate is brought into contact with A1 and A2 so that heat transfer is possible. By using the above manufacturing apparatus, even a laminated rubber having no through hole at the center can be manufactured in a short time and have excellent physical properties. In this case, a mold having no core A4 is used. Regardless of the presence or absence of the flange and the thickness and size of the raw rubber plate 1 and the steel plate 2, if it is a laminated rubber formed by alternately laminating a plurality of raw rubber plates 1 and the steel plate 2, it is manufactured in a short time as in the above embodiment. In addition, physical properties become excellent. In addition, the laminated rubber of the said embodiment is a raw rubber plate 1:38 sheets, steel plate 2:
Although it is composed of 37 sheets, it is not limited to this, and even if it is less or more than this, it will be similarly excellent. When a large thickness of laminated rubber is produced from a large number of raw rubber plates 1 and steel plates 2, the parallel electrode plates P1, P2 or
By changing the polarities of the lower dies A1 and A2 at regular intervals, it is possible to raise the temperature to the vulcanization temperature range in a short time with almost no temperature difference between the inside and the outside. In this case, it is necessary that the upper surface of the base 40 in the press machine be made of a non-conductive member. Instead of the raw rubber plate 1 of the above embodiment, a diene elastomer (for example, natural rubber), a non-diene elastomer, a thermoplastic elastomer liquid rubber, or the like can be used. A press plate of a press machine may be used also as an electrode. In the above embodiment, the press machine was operated from the beginning of the dielectric heating treatment. However, the present invention is not limited to this, and it is sufficient that the press machine be operated at least after the dielectric heating is completed.

[0028]

Since the present invention has the above-described configuration, it has the following effects.

From the contents described in the description of the embodiments of the invention, it is possible to withstand long-term use, all the raw rubber plates are heated substantially uniformly, and flange-type laminated rubber and square-shaped laminated rubber can be easily prepared.
