Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a cutting method for a honeycomb core used as a core material for a composite honeycomb sandwich panel or the like, and a mounting jig for cutting a honeycomb core.
[0002]
[Prior art]
For example, a honeycomb core is widely used as a core material laminated between two panels, that is, a core material for a so-called sandwich structure.
[0003]
This honeycomb core is formed by gathering a large number of cells into a honeycomb shape as a whole, and has mechanical characteristics such as high weight ratio strength. For example, an aircraft fuselage that requires light weight and high rigidity. Widely used in structural materials.
[0004]
However, since the cell walls forming each cell of the honeycomb core have low rigidity with respect to the load in the direction of tilting it, the cell walls fall down due to contact of the cutter blade during cutting, that is, cutting torque, Deformation, burrs, etc. may occur. For this reason, we are anxious about the fall of the surface accuracy of a cutting surface.
[0005]
A cutting method as a countermeasure is proposed by, for example, Japanese Patent Laid-Open Nos. 3-251329 and 6-179195.
[0006]
The former, Japanese Patent Laid-Open No. 3-251329, is a method in which a hard foamed plastic material is filled into a cell of a honeycomb core for cutting, and the latter, Japanese Patent Laid-Open No. 6-179195, is a fine particle inside the cell of a honeycomb core. After filling the non-metal in the shape, cutting is performed.
[0007]
Furthermore, as another method, the honeycomb core is placed on a jig, the lower part of the honeycomb core is immersed in liquid oil and fat, and then the oil and fat is hardened in a wax shape to fix the honeycomb core to the jig. A method of cutting is known.
[0008]
[Problems to be solved by the invention]
According to each of the above conventional examples, when the thickness of the honeycomb core is moderately large, cell wall collapse and burrs are prevented, and the surface accuracy of the cutting surface can be improved.
[0009]
However, in these conventional examples, when the thickness of the honeycomb core is thin, the plan view of the honeycomb core 100 is shown in FIG. 7A, and the longitudinal sectional view of the honeycomb core 100 is shown in FIG. When the edge of the honeycomb core 100 is formed into an acute wedge shape, in other words, when the thickness of the honeycomb core 100 is gradually reduced to sharpen the edge, the cutter 30 is subjected to cutting during the cutting process. Thus, it becomes difficult to sufficiently suppress the tilt deformation and burring of the cell wall 101 due to the cutting torque of 30 and the like, and as a result, the surface accuracy of the cutting surface, that is, the surface along the planned cutting line C is sufficiently secured There are things that cannot be done.
[0010]
This is because, for example, as shown in FIGS. 7A and 7B, in the portion where the thickness of the edge of the honeycomb core 100 is thin, the amount of the reinforcing material is insufficient as the thickness decreases. . Here, the reinforcing material is a member filled in the cell S in order to prevent the cell wall 101 from falling due to the cutting torque of the cutter 30 at the time of cutting. In the method of using hard foam plastic in the gazette, fine non-metal in JP-A-6-179195, or using fats and oils, the fats and oils correspond to the reinforcing material.
[0011]
In the cutting process of the honeycomb core 100, if the amount of such a reinforcing material is insufficient, when a load acts in a direction tilting with respect to the cell wall 101 due to the cutting torque of the cutter 30 or the like during the cutting process, Since the cell wall 101 cannot be held in a predetermined position, the cell wall 101 falls down as described above, and burrs or the like are generated, which may cause a reduction in surface accuracy of the cutting surface.
[0012]
Furthermore, when the amount of the oil or fat serving as the reinforcing material is insufficient, the oil or fat is lost due to vibration of the cutter 30 during cutting, and the bonding force of the honeycomb core 100 to the mounting jig is reduced. In particular, the loss of the oil and fat occurs remarkably at the periphery of the honeycomb core 100 shown by hatching in FIG. When cutting is performed with the cutter 30 in such a state, the honeycomb core 100 is lifted from the jig by the cutting torque of the cutter 30, and the surface accuracy of the cutting surface cannot be obtained.
[0013]
If the cut surface is not formed to have a uniform surface accuracy, that is, a flat surface, the panels 102 and 103 are bonded to the front surface side and the back surface side of the honeycomb core 100 as shown in FIG. When the sandwich structure is obtained, cracks may occur in the panels 102 and 103, or internal defects may occur due to gaps between the non-uniform cutting surface of the honeycomb core 100 and the panels 102 and 103. Is done. In other words, when the cutting surface of the honeycomb core 100 is non-uniform, the strength of the entire sandwich structure configured as a core material may be reduced.
[0014]
Therefore, the object of the present invention made in view of such points is to prevent the cell wall from falling and generating burrs even when the honeycomb core is thinly cut, and to ensure the surface accuracy of the cutting surface. A honeycomb core cutting method and a honeycomb core cutting jig are provided.
[0015]

[0019]
The invention of a mounting tool for cutting a honeycomb core according to claim 3 has a mounting surface for mounting the honeycomb core, and at least a lower part of the honeycomb core mounted on the mounting surface is made liquid by heating. In a mounting tool for cutting a honeycomb core, which is immersed in oil and fat and hardens the oil and fat to fix the honeycomb core on the mounting surface, a portion of the honeycomb core whose thickness is processed thinner than other portions If it is set as a thin processed part, the groove part for increasing the said fats and oils was provided in the part corresponding to the said thin processed part of the said attachment surfaces, It is characterized by the above-mentioned.
[0020]
According to the third aspect of the present invention, as in the first aspect of the present invention, the mounting surface is provided with a groove for increasing the amount of oil and fat in the portion corresponding to the thinned portion of the mounting jig. By increasing the bonding strength of the honeycomb core with respect to the cell wall, it is possible to prevent the cell wall from collapsing and the generation of burrs during the cutting with the cutter. In addition, problems such as oil and grease dropping off due to the vibration of the cutter during cutting are prevented, and the honeycomb core is not lifted from the mounting jig by the cutting torque of the cutter, etc. Accuracy is ensured.

[0027]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of a honeycomb core cutting method and a honeycomb core cutting jig according to the present invention will be described with reference to the drawings.
[0028]
(First embodiment)
A first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a plan view of the mounting jig 20 and the honeycomb core 10 fixed on the mounting jig 20, and FIG. 2 is a cross-sectional view taken along the line XX of FIG.
[0029]
In the following description, for the sake of convenience of explanation, regarding the honeycomb core 10 and the mounting jig 20 in the state of FIG. 1, the left part in the figure is the “rear end part”, the right part is the “front end part”, and the upper part The one end is referred to as “one end” and the lower end is referred to as “the other end”.
[0030]
The honeycomb core 10 to be cut in the present invention is a member formed by collecting a number of regular hexagonal cylindrical cells S into a honeycomb shape, and each cell S is formed of a foil-like substrate. It is surrounded by the cell wall 11.
[0031]
The honeycomb core 10 before cutting is formed in a substantially plate shape as shown in FIG. However, the honeycomb core 10 shown in FIG. 2 has the upper surface 12 formed horizontally, the lower surface 13 formed with the rear half 13a horizontally, and the front half 13b formed with the edge side inclined downward. . That is, the wall thickness T gradually increases in the first half. The shape of the lower surface 13 is determined in advance according to the shape of a panel (not shown) to be bonded after cutting. In the present embodiment, the case of cutting the honeycomb core 10 having the lower surface 13 as described above will be described as an example. However, the upper surface 12 and the lower surface 13 are both planar and are parallel to each other. Of course, the present invention can also be applied to the honeycomb core.
[0032]
Reference numeral 30 in the drawing is a cutter for cutting the honeycomb core 10, and a two-dot chain line straight line C indicates a planned cutting line by the cutter 30. In the present embodiment, as indicated by the planned cutting line C, the honeycomb core 10 is cut into a wedge shape with a sharp tip so that the thickness T gradually decreases as it moves to one end edge thereof. Is done.
[0033]
The mounting jig 20 is formed in a substantially rectangular plate shape in plan view. The mounting jig 20 is fixed on the cutting table 40 with a fastener (not shown) so that the lower surface 21 thereof is in close contact with the surface of the cutting table 40, and the upper surface side of the mounting jig 20 is around the periphery thereof. A flange portion 22 is erected. Of the upper surface, the surface surrounded by the flange portion 22 is an attachment surface 23 on which the honeycomb core 10 is placed, and the attachment surface 23 is formed in a shape matching the lower surface 13 of the honeycomb core 10. . That is, a horizontal surface 23a corresponding to the rear half 13a of the lower surface 13 of the honeycomb core 10 and an inclined surface 23b corresponding to the front half 13b are formed.
[0034]
A groove portion 24 is formed on the edge of the mounting surface 23 of the mounting jig 20, that is, on the tip side. Here, if a portion of the honeycomb core 10 whose thickness T is processed thinner than other portions is a thin-wall processed portion A, the thin-wall processed portion A is one of the honeycomb cores 10 as shown in FIG. From one end to the other end (hereinafter referred to as “longitudinal direction”), and the length in the longitudinal direction of the thin wall processed portion A is the same L1 as the length of the honeycomb core 10. . Here, the thin-wall processed portion A of the honeycomb core 10 is a portion of the honeycomb core 10 whose thickness becomes t (t <T) or less after cutting. The thin-wall processed portion A will be described in detail later. Describe.
[0035]
The groove portion 24 is provided in a portion corresponding to the thin wall processed portion A, and the groove portion 24 is set so that its length L2 is longer than the length L1 in the longitudinal direction of the thin wall processed portion A. Yes. The width W of the groove 24 is set to W1 in the portions 24a and 24b corresponding to one end and the other end in the longitudinal direction of the thin-wall processed portion A and the portion 24c corresponding to the center portion. In addition, the width W2 is set to be larger than the width W2 in the other portion, and the depth of the groove 24 is set to D.
[0036]
In order to fix the honeycomb core 10 to the mounting jig 20, oil or fat P as a reinforcing material is used. As the fats and oils P, for example, polyethylene glycol that becomes a liquid with high viscosity by heating and hardens at room temperature is used.
[0037]
Next, a method for cutting the honeycomb core 10 will be described.
[0038]
First, the mounting jig 20 is fixed on the cutting table 40 with a fastener (not shown).
[0039]
Subsequently, the honeycomb core 10 to be cut is placed at a predetermined position on the mounting surface 23 of the mounting jig 20. In this placement, the thin-wall processed portion A of the honeycomb core 10 is positioned so as to correspond to the groove portion 24.
[0040]
On the other hand, polyethylene glycol P as an oil or fat is heated to, for example, about 80 ° C. and melted to make a liquid with high viscosity. This liquid polyethylene glycol P is poured into the mounting surface 13 and the groove 24 of the mounting jig 20, and at least the lower part of the honeycomb core 10 is immersed in the polyethylene glycol P.
[0041]
After this injection, the polyethylene glycol P is allowed to cure at room temperature. The honeycomb core 10 is fixed to the mounting surface 23 of the mounting jig 20 by this curing.
[0042]
After fixing the honeycomb core 10, the cutter 30 is rotated and moved along the planned cutting line C, and unnecessary portions of the honeycomb core 10, that is, hatched portions above the planned cutting line C in the honeycomb core 10 are removed by cutting. .
[0043]
When the cutting of the honeycomb core 10 by the cutter 30 proceeds and the cutter 30 reaches the thinned portion A, conventionally, the polyethylene glycol P is chipped off by the vibration of the cutter 30, and the thinned portion A is removed from the mounting surface 23. There is a risk that the surface accuracy of the cutting surface may be lowered.
[0044]
However, in the present embodiment, since the groove portion 24 provided in the portion corresponding to the thin processed portion A and the lower portion of the honeycomb core 10 are filled with polyethylene glycol P as a reinforcing material and hardened, The thin-walled processed portion A is firmly held by the filled polyethylene glycol P, the bonding force between the mounting surface 23 and the honeycomb core 10 is increased, and the shape of at least the lower portion of the honeycomb core 10 is maintained. It is possible to prevent the thinned portion A from being lifted from the mounting surface 23 by the cutting torque or the like. Therefore, the cutting surface by the cutter 30 becomes a uniform smooth surface, and the surface accuracy of the cutting surface is ensured.
[0045]
Here, determination of the length L2, the widths W1 and W2, and the depth D of the groove 24 will be described. These dimensions are the mechanical strength after curing of polyethylene glycol P used as oil and fat, that is, the magnitude of the joining force when joining the honeycomb core 10 to the mounting surface 23, and the cutting of the honeycomb core 10 by the cutter 30. This also varies depending on the cutting torque acting on the thin processed portion A of the honeycomb core 10 from the cutter 30 and the thickness of the cell wall 11 during processing.
[0046]
Therefore, the dimensions of the groove 24 may be determined based on, for example, experiments. In other words, each dimension is determined so as to effectively prevent the thinned portion A from being lifted from the mounting surface 23 during cutting by the cutter 30 and exhibit a bonding force that can ensure the surface accuracy of the cutting surface. In addition, since it is necessary to remove the unnecessary polyethylene glycol P after the honeycomb core 10 is cut, in consideration of this, each dimension of the groove portion 24 is ideally minimized. It is preferable to set it so that the amount of polyethylene glycol P used is minimized.
[0047]
As is apparent from FIGS. 1 and 2, in the present invention, the groove portion 24 does not need to be provided so as to strictly correspond to the thin wall processed portion A. That is, the groove portion 24 may be provided corresponding to a portion of the honeycomb core 10 that requires further reinforcement with the polyethylene glycol P at the time of cutting with the cutter 30. In other words, the thin-wall processed portion A is not defined by the thickness t of the honeycomb core 10, but this thickness t is used as a guide only, and the portion of the honeycomb core 10 corresponding to the groove portion 24, that is, the reinforcement is necessary. It is reasonable to make the portion a thin processed portion A. The portion where the thickness of the honeycomb core 10 is thinner than t is not all the thin processed portion A, but the portion where the thickness is thinner than t and needs to be reinforced is the thin processed portion A.
[0048]
In the present embodiment, the groove width of the groove 24 is increased to W1 at both ends and the center in the longitudinal direction of the thin wall processed portion A to increase the bonding force. When the length in the direction is longer, for example, a portion W1 having a wide groove width may be provided between both end portions and the central portion.
[0049]
(Second Embodiment)
A second embodiment of the present invention will be described with reference to FIGS. 3 is a plan view of the mounting jig 20 and the honeycomb core 10 fixed on the mounting jig 20, and FIG. 4 is a cross-sectional view taken along line YY of FIG.
[0050]
Compared with the first embodiment, the present embodiment has a larger angle θ between the planned cutting line C of the honeycomb core 10 and the horizontal line, and the strength of the thin wall processed portion A is shown in FIGS. 1 and 2. When the height is higher than the honeycomb core, the groove widths of the portions 25a and 25b corresponding to both ends in the longitudinal direction of the thin wall processed portion A in the groove portion 25 are set to W1 as in the first embodiment. Unlike the first embodiment, the groove width of the portion 25c corresponding to the central portion may be set to W2 smaller than W1.
[0051]
(Third embodiment)
A third embodiment of the present invention will be described with reference to FIGS. FIG. 5 is a plan view of the mounting jig 20 and the honeycomb core 10 fixed on the mounting jig 20, and FIG. 6 is a sectional view taken along the line ZZ of FIG.
[0052]
When the length in the longitudinal direction of the thin wall processed portion A is long, as shown in FIG. 5 and FIG. 6, along the longitudinal direction of the groove portion 26, a portion having a wide groove width W 1 and a narrow groove width W 2. It is preferable to provide the portions alternately.
[0053]
According to the present embodiment, the bonding force of the honeycomb core 10 to the mounting jig 20 can be increased without increasing the groove width of the groove portion 26 as a whole. For example, a stronger bonding force than that of the first embodiment can be exhibited without unnecessarily increasing the amount of polyethylene glycol P used.
[0054]
Also in each of the first to third embodiments, the width of the groove where the bonding force needs to be increased is set wide, and the groove width of the unnecessary portion is made as narrow as possible. It is desirable to reduce the amount of glycol P.
[0055]
In the first to third embodiments, the example in which polyethylene glycol P is used as the oil for fixing the honeycomb core 10 to the mounting jig 20 has been described. However, the present invention has substantially the same function. It is also possible to use other than polyethylene glycol P, provided that
[0056]
The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the invention. For example, in each of the above embodiments, the case where the thin processed portion A has a wedge shape has been described. However, the present invention is not limited to this, and the upper surface and the lower surface of the honeycomb core 10 are not substantially parallel. However, the present invention can also be applied to a case where reinforcement is necessary at the time of cutting because the wall thickness is thin.
[0057]
Further, the case where the honeycomb core 10 is cut, that is, the case where the planar view shape of each cell is a hexagon has been described. However, the present invention is not limited to this, for example, the top view shape is a square or a rectangle. Also, it can be applied to corrugated cores and the like.
[0058]

Further, oil and fat are prevented from falling off due to the vibration of the cutter during the cutting process, and the honeycomb core is prevented from being lifted from the mounting jig by the cutting torque of the cutter, so that the surface accuracy of the cutting surface is ensured.
[0060]
Moreover, according to the above-described honeycomb jig cutting jig according to the present invention, the mounting surface of the mounting jig is provided with a groove portion for increasing the amount of oil and fat in the portion corresponding to the thin wall processed portion, and the mounting surface.
