Description

Pressurization device {PRESSURIZATION DEVICE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pressurization apparatus for isotropically pressurizing an object to be processed such as metals, ceramics, resins, foods, and the like, in particular, a high tension wire is wound around the outer periphery of the press frame to It is related with the improvement of the wire winding press frame type | mold pressurizing apparatus comprised so that it could endure by this high tension line.

Therefore, first, the conventional example which comprised the yoke of the wire winding press frame by the laminated board is demonstrated, referring FIGS. 7-10 below. Fig. 7 is a front view showing a wire winding press frame type pressing device according to a first conventional example, Fig. 8 is a side cross-sectional view showing arrow XX of Fig. 7, and Fig. 9 is a wire winding press according to a second conventional example. Front view before assembly attachment showing an embodiment of the frame, FIG. 10 (a) is a side cross-sectional view after assembly attachment showing arrow YY in FIG. 9, and FIG. 10 (b) is another view showing arrow YY in FIG. It is a side cross-sectional view after assembling of an Example.

In the wire winding press frame according to the first conventional example, a high-strength steel sheet is laminated to form a semicircular end member 20 and a column 21, and the semicircular end member 20 is attached to the bolt nut 22. It is fastened by. Further, the thick circular arc steel plate 23 is wound around the semicircular end member 20, and each column 21 is coated with a flat steel plate 24 having the same thickness. A high tension wire is wound around the thick circular arc steel plate 23 and the flat steel plate 24 to form an enclosure 25 (AW Astrop, "Wire-wound prestressed structures-the widening range of applications", Machinery and production engineering, Vol. 125, No. 3217, UK, Findlay Publ, Horton Kirby, 24 July 1974, pp. 98-105).

However, in the wire wound press frame according to the first conventional example, the thick circular arc steel plate 23 which does not share the axial load on the semicircular end member 20 has the same flat steel plate 24 in each column 21. Since it is provided, unnecessary weight is added and the weight of an expensive high tension wire also increases. In addition, although this press frame is used as an axial force support of a pressure vessel (not shown) in a pressurization apparatus, since the axial force load of the said pressure vessel is a circular load, even if a load is disperse | distributed to the upper and lower cover etc., the said semicircular end part The load applied to each of the plurality of laminated plates constituting the member 20 is not uniform, and the center of the pressure vessel in plan view has the highest load, and the load is lowered from the center toward the outer circumference in the radial direction. .

Therefore, the load displacement of the laminated board which comprises the said semicircular end member 20 differs in the vertical direction, respectively, and a step generate | occur | produces mutually. In particular, in a large pressure apparatus, this load displacement is large and adversely affects the bolt nut 22 for fastening the thick circular arc steel plate 23 and the semicircular end member 20. In addition, the difference in load displacement of the laminated plate is causing slip between the plates, which causes slip sound and loosening of the bolt and nut 22 with the load displacement.

As a remedy for this problem, a wire winding press frame according to the second conventional example has been proposed. This wire winding press frame is arranged between a pair of semi-circular yokes 30 and 31 and the yokes 30 and 31 as shown in Figs. 9 and 10 to set the space length inside the press. In the wire winding press frame consisting of the columns 32 and 33 for winding and winding the wire 34 against the axial force on the outer circumference in an aligned state, each of the semicircular yokes 30 and 31 is joined. The ends 32A and 33A of each column 32 and 33 are made to follow the bending curve 37 of the yoke 30 and 31 (refer Japanese Unexamined-Japanese-Patent No. 1-114199).

However, in the state where there is no load in a press frame, the edge 32A, 33A of each column 32, 33 joined to each of the semi-circular yoke 30, 31 is made into the bending curve of the yoke 30, 31 ( Even in the shape of 37), it is a very difficult technique to join the ends 32A, 33A and the yokes 30, 31 of the columns 32, 33, respectively, while applying a predetermined preliminary tension. As described above, when the yokes 30 and 31 are formed of laminated plates, it is difficult to absorb the load displacement and to eliminate the step difference between each of these laminated plates.

Further, although not described in Japanese Utility Model Application Publication No. Hei 1-1419999, also in the side cross-sections (see FIG. 10) of the yokes 30 and 31, the yoke 30 and 31 are bent when the press frame is loaded. Since a curve occurs, the end portions 32A and 33A of each column 32 and 33 need to be shaped to follow the bending curves of the side cross sections of the yokes 30 and 31, so that a very complicated joint shape is actually obtained. Will be.

Therefore, an object of the present invention is that the load displacements generated in the vertical direction of the laminated plate are different from each other due to uneven loads applied to each of the plurality of laminated plates constituting the semi-circular yoke of the pressurizing device, so that steps are generated. It is to provide a pressurization device capable of preventing the same.

That is, the pressurizing device which concerns on this invention which achieves the said objective is a pair of upper and lower semicircular yokes formed by laminating | stacking several plate-shaped members, the pressure vessel clamped between these upper and lower semicircular yokes, and this pressure A pressurization device disposed on an outer circumferential side of a container and configured to maintain a predetermined gap between the yokes, and an outer circumference of the yoke and the column integrally wound by a high tension line, the plate-shaped member of the semicircular yoke A yoke fitting means for penetrating in the stacking direction and simultaneously holding and integrating these plate-shaped members and provided at each abutting surface position between the laminated plate-like members, for regulating the up-down relative displacement between adjacent plate-like members, Plate member displacement control means is provided.

With the above-described configuration, since the displacement in the vertical direction of the butt face of the adjacent plate member is regulated by the plate member displacement regulating means, the occurrence of the displacement difference at the butt face is eliminated. Moreover, since the said yoke fitting support has the structure which extrapolated the annular fixing member concentrically, the shear force received from the displacement difference of each laminated plate member is alleviated.

The said plate-shaped member displacement control means can be set as the annular fixing member which has an annular shape and extrapolated concentrically at each abutting surface position between the said plate-shaped members by which the said yoke fitting support was laminated | stacked. Moreover, the said plate-shaped member displacement control means forms the step part by the plate thickness of each said adjacent plate-shaped member in the height of 1/4 or more of a radius of a yoke from the hydraulic surface of the said semicircular yoke, and makes it engage with each other. I can do it with a structure.

Further, in the pressurizing device of the present invention, the yoke fitting means and the annular fixing member have a height of 1/4 or more of the radius of the yoke from the pressure receiving surface of the semicircular yoke, and the semicircular center of the semicircular yoke Since it is arrange | positioned in the low stress area | region enclosed by the radius within 3/4 of a yoke radius from the said, even if the said yoke fitting means and the opening hole for the said annular fixing member were formed in the low stress area | region of the said semicircular yoke. Even if stress concentration is added, it does not become the weakest.

According to the present invention, it is possible to prevent a step from occurring with each other as a result of different load displacements generated in the vertical direction of the laminate due to uneven loads applied to each of the plurality of laminates constituting the semicircular yoke of the pressing device. A pressurization device can be provided.

Next, the pressurizing device which concerns on 1st Embodiment of this invention is demonstrated, referring attached FIG. 1 thru | or FIG. Fig. 1 is a sectional side view of the pressurizing device according to the first embodiment of the present invention, Fig. 2 is a side cross-sectional view showing arrow A-A in Fig. 1, and Fig. 3 is a flat cross-sectional view showing arrow B-B in Fig. 1.

In the pressing apparatus according to the first embodiment of the present invention, the press frame is formed by stacking a plurality of plate members 2a and 3a, respectively, and a pair of upper and lower semicircular yokes, that is, the upper yoke 2 and the lower yoke 3. ) And columns 4 for maintaining a predetermined interval at both ends of these semi-circular yokes 2, 3, and on the outer periphery of the semi-circular yokes 2, 3 and column 4, a piano wire ( The high tension wire 5 is wound while applying tension to form a piano wire winding layer, and is configured as the wire winding press frame 1. Reference numeral 7 is a side plate for regulating the width of the piano wire winding layer.

Moreover, in the pressurization apparatus which concerns on the 1st Embodiment of this invention, the pressure container 13 interposes between the said upper yoke 2 and the lower yoke 3 through the upper cover 14 and the lower cover 15. The semicircular yokes (2, 3) and the column (4) are supported, even if high pressure is loaded inside the pressure vessel (13) and a design load is applied to the semicircular yokes (2, 3). The preliminary compressive force in which a gap does not generate | occur | produce in the joining surface of this column 4 is provided.

Further, tie rods (yoke fitting means) which penetrate the plate members 2a and 3a of the semicircular yokes 2 and 3 in the lamination direction, and hold and integrate these plate members 2a and 3a respectively. (6) and an annular coater (annularly extrapolated) concentrically extrapolated at respective abutting surface positions between the plate members (2a, 3a) having an annular shape and stacked in the axial direction of the tie rod (6). Fixing member) 8 is provided.

As a result of the linear winding press frame 1 receiving a circular load in the vertical direction from the pressure vessel 13 through the upper lid 14 and the lower lid 15, for example, the lower yoke hydraulic pressure surface 12 The plate surface displacement at the time of pressurization may be convex downward, as indicated by the double-dot chain line in FIG. 1, and the side cross-section displacement at the time of pressurization may be shown at the bottom convex shape as indicated by reference numeral 12b in FIG. 2. .

The plate surface displacement at the time of pressurization of the upper yoke pressure receiving surface 11 and the side cross-sectional displacement at the time of pressing are also convex upwards, in contrast to the above. In the laminated yoke according to the prior art, as described in the wire winding press frame according to the second conventional example, the yoke-side cross-sectional displacement at the time of pressing becomes a step shape for each of the plate members 2a and 3a, and these plate members (2a, 3a) It adversely affects the piano wire wound on the outer periphery. In general, the displacement difference between the center and the outside of the yokes 2 and 3 is around 10%, and the absolute value of the displacement difference increases in the large frame with the long column 4.

Therefore, by adjoining the annular coater 8 concentrically at each abutting surface position between the plate members 2a, 3a having an annular shape and stacked in the axial direction of the tie rod 6, the adjacent plate shapes The displacement difference between the members 2a and 3a is regulated. Shear force acts on the annular coater 8, but as described above, the difference in displacement between the center and the outside of the yokes 2 and 3 is about 10%, and each of the plate members 2a and 3a is about a purchase so that the adjacent plate-like The displacement difference between the members 2a and 3a is about several percent. Therefore, the supporting surface of several% of the area of the column 13 which contact | connects the said plate-shaped member 2a, 3a should just be the vertical projection area of each annular coater 8, and the magnitude | size of the annular coater 8 Need not be huge.

In addition, in the pressurization apparatus which concerns on the 1st Embodiment of this invention, when the upper yoke 2 is demonstrated using FIG. 1, the said tie rod 6 and the annular coater 8 will be the said upper yoke hydraulic pressure. Low (1) having a height H1 of the yoke radius R from the face 11 and surrounded by a radius R1 within 3/4 of the yoke radius R from the yoke semicircle center O; It is preferable to arrange | position in the stress area | region 10. Similarly, when the lower yoke 3 is described, the tie rod 6 and the annular coater 8 have a height of 1/4 or more of the yoke radius R from the lower yoke pressure receiving surface 12, Furthermore, it is preferable that it is arrange | positioned in the low stress area | region (not shown) surrounded by the radius within 3/4 of the yoke radius R from the semicircle center of the said lower yoke 3.

When the semicircular yokes 2 and 3 are considered to have a beam structure in which an equally distributed load by line winding is loaded on an arc-shaped beam supported at both ends by the column 4, a concentrated load is applied to a semicircular cut edge at the time of pressing. It is approximated to the beam supported by the equal distribution to the circular arc part. Bending stress acts on the semicircular yokes 2, 3, and the outer edges of the cut edges and the arcs of the yokes 2, 3 are high stresses, but within the low stress region 10 less than 1/2 of them. Low stress.

Therefore, if the opening hole for the tie rod 6 or the annular coater 8 is formed in the said low stress area | region 10, even if it adds the stress concentration by the said opening hole, it will not become the weakest. The low stress region 10 is located at the center of the beam model and is a region where the relative change at the time of removing the pressurized load is small, and the tie rod 6 and the annular coater 8 are attached to the semicircular yokes 2 and 3. Since a pair of) is provided, even if a displacement difference occurs in each of the plate members 2a and 3a, it is hardly affected.

As described above, according to the pressing device according to the first embodiment of the present invention, the plate-like members 2a and 3a of the semicircular yokes 2 and 3 are penetrated in the lamination direction, respectively, and the plate-like members 2a and 3a are sandwiched. An annular coater 8 which is concentrically extrapolated concentrically at each abutting position between the tie rod 6 supporting and integrating and the plate members 2a and 3a in which the tie rod 6 is stacked. Is provided, the displacement of the up-down direction of the abutting surfaces of the adjacent plate-shaped members 2a and 3a is regulated, and generation | occurrence | production of the displacement difference in abutting surface is eliminated. Moreover, since the said tie rod 6 has the structure which extrapolated the annular coater 8 concentrically, the shear force received from the displacement difference of each laminated plate member 2a, 3a is alleviated.

Further, the tie rod 6 and the annular coater 8 have a height H1 of 1/4 or more of the yoke radius R from the hydraulic pressure surfaces 11 and 12 of the semicircular yokes 2 and 3. And a low stress area 10 surrounded by a radius R1 within 3/4 of the yoke radius R from the yoke semicircle center O, so that the semicircular yoke 2, Even if the opening hole for the tie rod 6 and the annular coater 8 is formed in the low stress region 10 of 3), even if the stress concentration caused by the opening hole is added, it does not become the weakest.

Next, the pressurizing device which concerns on 2nd Embodiment of this invention is demonstrated, referring attached FIG. 4 thru | or FIG. 6 below. Fig. 4 is a sectional view of the pressing device according to the second embodiment of the present invention, Fig. 5 shows an arrow CC in Fig. 4, a side cross-sectional view when the plate member is an odd sheet, and Fig. 6 shows an arrow CC in Fig. 4. It is a side sectional drawing in the case where a plate-shaped member is an even number sheet.

The second embodiment of the present invention differs from the first embodiment in that there is a difference in the configuration of regulating the displacement in the vertical direction of the plate-like member constituting the semicircular yoke, and since it is otherwise completely the same configuration, It is only a description about the structure which regulates the displacement of this plate-shaped member in the up-down direction.

That is, in the structure which regulates the displacement of the plate-shaped member which comprises the semi-circle yoke which concerns on the 1st aspect of this invention in the up-down direction, each plate-shaped member 2a, 3a of the said semi-circular yoke 2, 3 is carried out. Between the tie rods 6 penetrating in the stacking direction and simultaneously holding and integrating these plate members 2a and 3a, and the plate members 2a and 3a having an annular shape and having the tie rods 6 laminated thereon. The annular coater 8 which was concentrically extrapolated at each abutting surface position was provided.

On the other hand, in the structure which regulates the displacement of the plate-shaped member which comprises the semi-circle yoke which concerns on 2nd Embodiment of this invention, the some plate-shaped member which forms said semi-circle yoke 2, 3, respectively ( 2a, 3a adjoins each plate-shaped member 2a in the height H2 of 1/4 or more of the yoke radius R from the hydraulic pressure surfaces 11 and 12 of each semicircular yoke 2 and 3, respectively. , 3a) is formed in a structure in which the stepped portion 9 is formed to mesh with each other.

In this case, when the plate members 2a and 3a are odd-numbered as shown in Fig. 5, the stepped portions 9 are also formed in the stacked central plate members 2a and 3a, respectively, but the plate members 2a When 3a is an even number as shown in FIG. 6, it is not necessary to form the step part 9 in the abutment surface of each plate-shaped member 2a, 3a of the laminated center. This is because there is no meaning to restrict both because the displacements in the left and right up and down directions are symmetrical with respect to the butt surfaces of the respective plate-shaped members 2a and 3a stacked in FIG. 6.

As described above, according to the pressurizing device according to the second embodiment of the present invention, the stepped portion 9 is provided on abutting surfaces of the plurality of plate members 2a and 3a respectively forming the semicircular yokes 2 and 3. Is formed, the displacement of the up-down direction is restricted in the abutting surfaces of adjacent plate member 2a, 3a, and generation | occurrence | production of the displacement difference in abutting surface is eliminated. In addition, the annular coater 8 becomes unnecessary by providing the stepped portion 9 on the mating surfaces of the plate members 2a and 3a.

As described above, according to the pressing apparatus according to the present invention, yoke-fitting means for penetrating the plate-shaped members of the semi-circular yoke in the stacking direction, and holding and integrating these plate-shaped members with the annular shape, has a toric shape. Since the annular fixing member concentrically extrapolated at each abutting surface position between the plate members on which the supporting means are stacked is provided, displacement of the butting surfaces of adjacent plate-like members by the annular fixing member is prevented. It is regulated and generation | occurrence | production of the displacement difference in abutting surface is eliminated.
