[0006]
【Example】
Next, an embodiment of a pressure processing apparatus for performing a pressure method according to the present invention will be described with reference to the drawings. FIG. 1 shows an entire configuration of an embodiment of a pressure processing apparatus according to the present invention.
[0007]
As shown in the figure, the pressure processing apparatus 100 includes a tray 1 as a processing frame, a pair of opposed spacer receiving members 3a and 3b as a pair of opposed receiving members, and both spacer receiving members 3a and 3b. And a wedge-shaped spacer 2 which is a space holding tool to be mounted inside the opposed space.
[0008]
Further, a plurality of slide rods 6 are provided in the tray 1, and the slide rod 6 has an opening which is in contact with a surface of the spacer receiving metal member 3 a opposite to the surface facing the spacer receiving metal member 3 b and through which the slide rod 6 is inserted. 6, a slide plate 4b is provided so as to be movable in the longitudinal direction, and a reaction force plate 7b is provided in contact with a surface of the spacer receiving metal member 3b opposite to a surface facing the spacer receiving metal member 3a. The surface is in contact with one side wall of the tray 1.
[0009]
A slide plate 4a is provided to face the slide plate 4b and has an opening through which the slide rod 6 is inserted so as to be movable in the longitudinal direction of the slide rod 6, and a compression spring 5 is provided on the other surface of the slide plate 4a. The compression spring 5 is in contact with the reaction force plate 7a, and the other surface of the reaction force plate 7a is in contact with the other side wall of the tray 1.
[0010]
A pressing device 8 is disposed between the slide plate 4b and the reaction force plate 7b, and the slide plate 4b is moved by an electric drive source such as a motor or a liquid pressure drive source such as a hydraulic cylinder. 6 can be freely moved in the longitudinal direction.
[0011]
The opposing surfaces of the pair of spacer receiving members 3a and 3b are formed in an inclined shape such that the opposing interval becomes gradually narrower from one end to the other end. Further, the wedge-shaped spacer 2 has a pair of opposing working surfaces, and each working surface is formed in the same inclined shape as the opposing surfaces of the spacer receiving metal members 3a and 3b.
[0012]
Next, a method of manufacturing a disk pad using the above-described pressure processing apparatus 100 will be described with reference to FIG.
First, a predetermined number of uncured objects to be heated 10 are inserted between the slide plates 4a and 4b via the spacers 9. Here, the object to be heated 10 corresponds to a material to be pressed. Next, the slide plate 4b is pressed by the pressing device 8. The compression spring 5 is compressed by the pressing force, and accordingly, the slide plate 4b moves in the direction of the slide plate 4a. For this reason, the facing distance between the spacer receiving metal members 3a and 3b increases. The wedge-shaped spacer 2 is inserted into the enlarged opposing space, and the wedge-shaped spacer 2 is pushed in until the predetermined space is reached. By this operation, the pressing with a predetermined pressing force on the object to be heated can be maintained.
[0013]
In this case, a frictional force acts between the working surface of the wedge-shaped spacer 2 and the opposing surfaces of the spacer receiving metal members 3a and 3b. If the force for extracting the wedge-shaped spacer 2 from the opposing interval is F ', the extraction force F' is The following equation F ′ = {sin (2λ−α) cossλ ′} / {cos (λ + λ′−α) cosλ} (1)
Is represented by Here, λ represents the friction angle when the wedge-shaped spacer 2 is pushed in, λ ′ represents the friction angle when the wedge-shaped spacer 2 is pulled out, and α represents the inclination angle of the working surface of the wedge-shaped spacer 2. In the above equation (1), if the condition of 2α <λ is satisfied, the frictional force between the opposing surfaces of the spacer receiving metal members 3a and 3b and the operating surface of the wedge-shaped spacer 2 tends to cause the wedge-shaped spacer 2 to escape. The wedge-shaped spacer 2 stops at that position, and the set interval is maintained.
[0014]
Further, if the tray 1 is used as a heating frame, and a large number of objects to be heated are housed in a stacked state inside the tray 1 via the spacer 9 and are subjected to the heat treatment while being pressed and held, a wide range of intervals can be obtained. Heat treatment can be performed while corresponding to the pressing force.

Next, an embodiment of the spacing member used in the pressure processing apparatus according to the present invention will be described with reference to the drawings. FIG. 3A shows an entire configuration of a wedge-shaped spacer which is an embodiment of the spacing member.
[0016]
As shown in the figure, this wedge-shaped spacer 2A is formed in a hexahedron, and has three pairs of working surfaces S1 and S2, S3 and S4, and S5 and S6, which are opposed to each other. It is formed in an inclined shape in which the facing interval becomes gradually narrower from the (wide end) to the other end (narrow end).
[0017]
Further, the wedge-shaped spacer 2A is configured such that the interval between the narrow ends or the wide ends of the pair of working surfaces is substantially the same as the interval between the wide ends or the narrow ends of the other pair of working surfaces and is continuous. I have. That is, as shown in FIG. 3B, when attention is paid to the wedge shape formed by the first pair of operation surfaces (S1, S2), a pair of operation surfaces at the narrow end AB of the wedge shape. The interval between (S1, S2) is L1, and the interval between the pair of working surfaces (S1, S2) at the narrow end DC is L2.
[0018]

The distance between the surfaces (S3, S4) is L3, and the distance between the pair of working surfaces (S3, S4) at the narrow end ED is L4.
[0019]
Then, as shown in FIG. 3D, when attention is paid to the wedge shape formed by the third pair of operation surfaces (S5, S6), a pair of operation surfaces at the narrow end AD of the wedge shape is used. The interval between (S5, S6) is L5, and the interval between the pair of working surfaces (S5, S6) at the narrow end FE is L6.
[0020]
Further, the distance L2 between the wide ends DC of the first pair of working surfaces (S1, S2) is set to be substantially equal to the distance L3 between the narrow ends FA of the second pair of working surfaces (S3, S4). Have been. The distance L4 between the wide ends ED of the second pair of working surfaces (S3, S4) is set substantially equal to the distance L5 between the narrow ends AD of the third pair of working surfaces (S5, S6). Have been.
[0021]
With the above-described configuration, for example, when an interval is set using a pair of operating surfaces (S1, S2) and an interval longer than the interval L2 between the wide ends DC of the operating surfaces is to be set, Since there is another pair of operating surfaces (S3, S4) having a narrow end interval L3 substantially matching the wide end interval L2, the interval can be set using this pair of operating surfaces (S3, S4). Good. By repeating the above operation, at least three pairs of working surfaces, for example, a pair of working surfaces (S1, S2), (S3, S4), and (S5, S6) are pressed by the one wedge-shaped spacer 2A by holding the gap. Pressing can be performed at a wide range of intervals ranging from L1 to L6.
[0022]
Next, another embodiment of the spacing member used in the present invention will be described. FIG. 4 shows a configuration of a wedge-shaped spacer 2B which is another embodiment of the spacing member. As shown in the figure, the wedge-shaped spacer 2B is formed in an octahedron, and has three pairs of operating surfaces S11 and S12, S13 and S14, and S15 and S16 facing each other. It is formed in an inclined shape in which the facing interval becomes gradually narrower from the (wide end) to the other end (narrow end).
[0023]
Further, the wedge-shaped spacer 2B is configured such that the interval between the narrow ends or the wide ends of the pair of working surfaces is substantially the same as the interval between the wide ends or the narrow ends of the other pair of working surfaces and is continuous. I have. That is, as shown in FIG. 4B, when attention is paid to the wedge shape formed by the first pair of operation surfaces (S11 and S12), the pair of operation surfaces at the narrow end mj of the wedge shape is used. The interval between (S11, S12) is L11, and the interval between the pair of working surfaces (S11, S12) at the narrow end fd is L12.
[0024]
In addition, as shown in FIG. 4B, when attention is paid to the wedge shape formed by the second pair of operation surfaces (S13, S14), a pair of operation at the narrow end mh of the wedge shape is performed. The distance between the surfaces (S13, S14) is L13, and the distance between the pair of working surfaces (S13, S14) at the narrow end fb is L14.
[0025]
Then, as shown in FIG. 4B, when attention is paid to the wedge shape formed by the third pair of operation surfaces (S15, S16), a pair of operation at the narrow end gk of the wedge shape is performed. The distance between the surfaces (S15, S16) is L15, and the distance between the pair of working surfaces (S15, S16) at the narrow end ae is L16.
[0026]
Further, the interval L12 between the wide ends fd of the first pair of operating surfaces (S11, S12) is set to be substantially equal to the interval L13 between the narrow ends mh of the second pair of operating surfaces (S13, S14). Have been. The distance L14 between the wide ends fb of the second pair of working surfaces (S13, S14) is set to be substantially equal to the distance L15 between the narrow ends gk of the third pair of working surfaces (S15, S16). Have been.
[0027]
With the above configuration, for example, when an interval is set using a pair of action surfaces (S11, S12) and an interval longer than the interval L12 of the wide end fd of the action surface is to be set, Since there is another pair of working surfaces (S13, S14) having a narrow end spacing L13 substantially matching the wide end spacing L12, if the spacing is set using this pair of working surfaces (S13, S14). Good. By repeating the above operation, at least three pairs of working surfaces, for example, a pair of working surfaces (S11, S12), (S13, S14), and (S15, S16) are pressed by one wedge-shaped spacer 2B by holding the gap. Pressing can be performed at a wide range of intervals ranging from the intervals L11 to L16.
[0028]
Note that the present invention is not limited to the above embodiment. The above-described embodiment is an exemplification, and has substantially the same configuration as the technical idea described in the claims of the present invention, and any device having the same operation and effect can be realized by the present invention. It is included in the technical scope of the invention.
[0029]
For example, in the above embodiment, the case where the wedge-shaped spacer is a hexahedron and an octahedron has been described. However, the present invention is not limited to this. In other words, any shape may be used as long as it is a pentahedron or more polyhedron and the spacing between two or more opposing opposing surfaces is substantially continuous.
[0030]
That is, in the above-described embodiment, an example in which three pairs of working surfaces facing each other are provided on the wedge-shaped spacer has been described. However, the present invention is not limited to this, and two or more pairs of working surfaces are provided on the wedge-shaped spacer. Is good enough.

As described above, according to the present invention having the above-described configuration, a pair of receiving members are provided on one side of the inside of the processing frame instead of the conventional set bolts, and the pair of receiving members are mounted inside the opposed space between the two receiving members. The spacing member is provided, and the opposing surfaces of the pair of receiving members are formed in an inclined shape in which the facing distance gradually narrows from one end to the other end, and the spacing member is provided with a pair of opposing working surfaces. Each working surface is formed so as to have the same inclined shape as the facing surface of the receiving member, and the interval between the narrow end or the wide end of the pair of working surfaces is the wide end or the width of any other pair of working surfaces. Since it is configured to be continuously changed by substantially matching the interval between the narrow ends, the material to be pressed is disposed between the other inside of the processing frame and the outer surface of one of the receiving members, and one of the receiving members is disposed. In a state where the member to be pressed is pressed so as to expand the facing distance by pressing the member, If mounted inside distance retainer of opposing distance of the receiving member, either by holding the pressure of both receiving member using a pair of working surfaces of the pressure treatment member can be clamped. In this case, when pressing is performed by holding the gap using a pair of working surfaces with a space holding tool, and when trying to perform pressing by holding a space equal to or larger than the space between the wide ends of the working surface, Since there is another pair of working surfaces having a narrow end interval substantially corresponding to the wide end interval, the interval may be maintained and pressed using the corresponding pair of operating surfaces. By repeating the above operation, it is possible to cope with the pressing force in a wide range of intervals.
Also, if the processing frame is a heating frame, and a large number of materials to be pressed are housed in a stacked state through a spacer inside the processing frame and heated and held in a pressed state, a wide range of intervals can be obtained. The heat treatment can be performed while corresponding to the pressing force in the above.
Therefore, there is an advantage that the stop management of the set bolt with high accuracy is not required, the pressurizing process is simplified, the work efficiency is improved, and the cost can be reduced.
