Description

The present invention relates to a honeycomb structure. That is, the present invention relates to a honeycomb structure in which cells are formed by alternately assembling a corrugated plate material and a flat plate material.

"Prior Art" A honeycomb structure is composed of a planar assembly of hollow columnar cells, and each cell has conventionally been, for example, a regular hexagon or other uniform shape and the same size. Further, the honeycomb structure has conventionally been used with its cell end faces oriented in the direction in which an external force acts for reasons of strength.

Note that these are the same regardless of whether the honeycomb structure manufactured by a so-called spread type is a so-called corrugated type, that is, a honeycomb structure manufactured by alternately assembling corrugated plate materials and flat plate materials. It was

"Problems to be Solved by the Invention" The following problems have been pointed out in such a conventional honeycomb structure.

First, it is pointed out that each cell has a uniform shape and the same size, that is, it has a uniform density, so that the overall shape is simple and a changed composite shape cannot be obtained, and the applications etc. are limited. there were.

Secondly, it was used with its cell end face oriented in the direction in which an external force acts. That is, for strength reasons, the use of the surface facing the cell end face at right angles to the direction in which the external force acts, that is, the cell size direction, has not been performed because the strength becomes weak. Thus, it has been pointed out that the use is limited because the use surface is directionally limited.

Thirdly, generally, in order to improve the strength, the cell size is reduced to increase the cell density, or the material thickness is increased. However, as a result, the weight is increased, and there is a problem that the characteristics of the honeycomb structure cannot be utilized.

Fourthly, it was pointed out that the expandable honeycomb structure was more time-consuming to manufacture and the yield was worse and the material was wasted more than the corrugated honeycomb structure.

 In the prior art, such a point was pointed out.

The present invention has been made in order to solve the problems of the conventional example in view of such a situation, between the flat plate material consisting of the parallel plate and the partition plate, by alternately assembling the corrugated plate material, The shape and size of each cell change, the use surface is not limited in direction, the weight ratio strength is excellent, and the manufacturing is easy and the yield is good. The purpose is to propose a honeycomb structure.

"Means for Solving the Problems" The technical means of the present invention for achieving the object is as follows.

In this honeycomb structure, corrugated sheet materials in which corrugated irregularities are continuously bent and formed and flat plate materials are alternately assembled.

In the corrugated plate material, the size of the space formed by the corrugated irregularities gradually changes.

The flat plate member is composed of a plurality of parallel plates arranged in parallel at a predetermined interval, and a partition plate which is inclined and connects the parallel plates.

"Operation" The present invention operates as follows because it is constituted by such means.

In this honeycomb structure, corrugated sheet materials whose space size gradually changes are alternately assembled in the spaces between the flat plate materials in which the parallel plates are connected by the inclined partition plates.

Therefore, in this honeycomb structure, firstly, the cells formed are gradually changed in shape and size, and the density is gradually changed. That is, since each cell is partitioned and formed by each space of the corrugated sheet material and the parallel plate or the partition plate of the flat plate material, its shape and size gradually change.

Secondly, its surface of use is not directionally restricted. That is, the parallel plates of the flat plate member are connected and reinforced by the partition plate, and the corrugated plate member is interposed therebetween. Therefore, the surface perpendicular to the cell end surface, that is, the cell size direction is also strongly reinforced by such a partition plate. Therefore, it is of course possible to use the cell end surface facing the direction in which the external force acts, and also to use the surface facing the cell end surface at a right angle.

Thirdly, the weight-specific strength is also excellent. That is, as described above, since the flat plate member is strongly reinforced by the partition plate and the like, the overall strength is remarkably superior to that of the same weight.

Fourthly, since it is manufactured by assembling the corrugated plate material to the flat plate material, the manufacturing is easy and the yield is good.

"Examples" Hereinafter, the present invention will be described in detail based on examples shown in the drawings.

First, the configuration and the like will be described in order of the outline of the honeycomb structure and the manufacturing method thereof.

 The outline of the honeycomb structure is as follows.

FIG. 1 is a front view showing a first embodiment of the present invention.
FIG. 2 is a front view of the second embodiment. FIG. 3 is a front view of the third embodiment. FIG. 4 is a front view of the fourth embodiment.

In this honeycomb structure, corrugated sheet materials 1 in which corrugated irregularities are continuously bent and formed, and flat plate materials 2 are assembled alternately.

First Wave plate 1, the size of the space 1 ₁ is formed by irregularities of the waveform has changed gradually. That is, the pitch or the wave height of the waves or by gradually changing the both, the space 1 ₁ of size formed as folding gap is changing gradually.

The flat plate member 2 is composed of a plurality of parallel plates 3 arranged in parallel vertically in the drawing at predetermined equal intervals, and a partition plate 4 which is inclined and connects the parallel plates 3. That is, in the illustrated example, the partition plate 4 is formed by bending in a polygonal line shape with equal pitch and equal height, and is interposed between the parallel plates 3, and the tops and valleys of the top and bottom parallel plates 3 are respectively interposed. It is firmly joined and fixed by adhesives, brazing materials, etc.

Various arrangement positions of the partition plates 4 can be considered. For example, in the first embodiment shown in FIG. 1, the valleys and the peaks of the upper and lower partition plates 4 are aligned at substantially the same position via the single parallel plate 3. In the second embodiment of FIG. 2, the partition plates 4 are laterally displaced from each other by a half pitch with respect to the first embodiment, and the opposing portions of the upper and lower partition plates 4 are all parallel. . In the third and fourth embodiments shown in FIGS. 3 and 4, the partition plate 4 is further laterally displaced from the second embodiment by a quarter pitch.

In the fourth embodiment of FIG. 4, intervening plates 5 are vertically provided between the tops and valleys of the partition plate 4 and the parallel plate 3, and their upper and lower ends are joined and fixed. By including such an intervening plate 5, the honeycomb structure of the fourth embodiment has an advantage that the flat plate member 2 is strongly connected and reinforced and the strength is extremely excellent.

The corrugated sheet material 1 is filled in the space defined by the parallel plate 3 and the partition plate 4 of the flat plate material 2 as described above. The top and valley of each corrugation of the corrugated sheet material 1 are joined and fixed to the parallel plate 3 or the partition plate 4 with an adhesive, a brazing material, or the like. In this way, for example, a honeycomb structure as in the first, second, third and fourth embodiments is formed. That is the independent space by the respective space 1 ₁ parallel plate 3 and the partition plate 4 of the wave plate material 1, with each cell 6 of the hollow columnar shape is formed. Then, these cells 6 are aggregated in a plane to form a honeycomb structure.

 The outline of the honeycomb structure is as described above.

 Next, an example of the manufacturing method will be described.

FIG. 5 is used to explain the method of manufacturing the corrugated sheet material 1.
The figure is a perspective view of the corrugating device 7, and (2) is a perspective view of the manufactured corrugated sheet material 1. The corrugating device 7 is provided with a pair of corrugating rollers 8 which are driven to rotate. For example, triangular corrugated teeth are formed on the outer circumference of the corrugating rollers 8 at equal intervals, and the corrugating rollers 7 and 8 have a substantially gear shape. There is. Then, by passing a long plate 9 which is a metal foil of material between the corrugated rollers 8 of the corrugated device 7, conventionally, as shown in FIG. 5 (1), the corrugated uneven shape is formed. The corrugated sheet 10 having the same size of the space to be formed was continuously bent.

Now the wave plate 1 used in the present application, the size of the space 1 ₁ is formed by irregularities of as described above waveform has been processed bent so as to change gradually. Therefore, in manufacturing the corrugated sheet material 1 with the illustrated corrugating device 7, the following first, second, and third cases can be considered.

First, at the time of manufacturing, one of the corrugated rollers 8 is moved toward and away from the other so that the axial distance between the two is controlled so as to gradually change. Then, the bent corrugated sheet material 1 is formed so that the wave pitch is the same and the wave height is gradually changed. By thus the height of the wave is changed, the size of the space 1 ₁ is formed a wave plate 1 is obtained in which changes gradually.

Secondly, the number of rotations of the corrugated rollers 8, 8 is changed at the time of manufacturing, and the rotation is controlled so that the rotation becomes slower or faster. As a result, the bent corrugated sheet material 1 is formed into a corrugated sheet in which the wave pitch gradually changes and the wave height is the same. By changing the pitch of the waves in this way,
Wave plate 1 is obtained size of the space 1 ₁ is formed is changed gradually.

Thirdly, the above-described first and second are used together, and control is performed so that both the axial distance and the rotational speed of the corrugated rollers 8 change during manufacturing. Then, the bent corrugated sheet material 1 is formed in such a manner that both the pitch and height of the waves gradually change, as shown in FIG. 5 (2). By changing the pitch and height of the waves in this way, the space formed 1 ₁
The corrugated sheet material 1 whose size is gradually changed is obtained. The corrugated sheet material 1 is manufactured as described above, for example.

Of course, the corrugated rollers 8 and 8 of the corrugated device 7
The corrugated sheet material 1 having various uneven shapes other than those shown in the drawing can be manufactured by variously changing the shape and the number of teeth of the uneven teeth, and is used for the honeycomb structure of the present invention.

 The manufacturing method and the like are as described above, for example.

 The above is the description of the configuration and the like.

 The operation and the like will be described below.

In this honeycomb structure, the flat plate member 2 and the corrugated plate member 1
Are assembled alternately. That this honeycomb structure, the space between the inclined separation plate 4 flat plate 2 which is parallel plate 3 fixedly connected by, wave plate 1 that varies the size of the space 1 ₁ it is gradually is filled, alternately It is assembled and fixed.

Therefore, this honeycomb structure has the following first, second, third, fourth
It becomes like.

The first formed cells 6 gradually change in shape and size and gradually differ in density. That is, each cell 6 of the honeycomb structure, because it is defined and formed by a parallel plate 3, or the partition plate 4 of the space 1 ₁ and the flat plate 2 wave plate 1, the shape and the size is changed gradually There is. And the corrugated sheet material 1 is
Since various shapes are easily obtained as described above, honeycomb structures having various cell 6 shapes can be easily obtained.

Secondly, the honeycomb structure is not limited in its direction of use. That is, the parallel plates 3 of the flat plate member 2 are connected and reinforced by the partition plate 4, and the corrugated plate member 1 is interposed therebetween. Therefore, the surface that is perpendicular to the cell end surface, that is,
The cell size direction, for example, the vertical direction in FIG. 4 is also strongly reinforced by the partition plate 4 and the like. Therefore, the cell end face, that is, the first, second, and
It can be used with the cell end face in Figures 3 and 4 facing,
It is also possible to use it by directing the surface perpendicular to the cell end surface, that is, the surface formed by the upper and lower parallel plates 3 in FIGS.

Thirdly, this honeycomb structure is also excellent in weight specific strength. That is, as described above, since the flat plate material 2 is strongly reinforced by the partition plate 4 and the like, the overall strength is remarkably superior to that of the same weight.

Fourthly, this honeycomb structure is manufactured by filling and assembling the corrugated sheet material 1 in the space defined by the parallel plate 3 and the partition plate 4 of the flat plate material 2.
Therefore, it is easier to manufacture and has a higher yield than the conventional expansion type.

 The above is the description of the operation and the like.

[Effects of the Invention] As described above, the honeycomb structure according to the present invention exhibits the following effects by alternately assembling corrugated plate materials between flat plate materials including parallel plates and partition plates.

First, the shape and size of each cell change gradually, and the density gradually changes, so that the overall shape can be obtained in various unique composite shapes, which are widely used in various applications.

Secondly, the use surface is not directionally restricted. That is, it is possible to use the cell end surface facing the direction in which the external force acts, and it is also possible to use the surface facing the cell end surface at a right angle, that is, the cell size direction. In this way, the usage surface can be selected at any time, so it is easy to use.
The range of use is greatly expanded.

Thirdly, it has excellent strength to weight ratio. In other words, it is light and has excellent strength, such as being extremely strong against various external forces such as compression, shearing, bending, and twisting without increasing the cell density and keeping the material thickness thin.

Fourth, it has the features of a so-called corrugated type, such as easy manufacture, good yield, and no waste of material.

As described above, all the problems existing in this type of conventional example are swept away at once, and the effect exhibited by the honeycomb structure of the present invention is remarkably great.
