Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a conjugate and a coupling method.
[0002]
[Prior art]
Conventionally, as a method of joining two metal members, there are joining methods such as cold welding method, hot welding method, explosive pressure bonding method, diffusion method, etc. in addition to methods such as welding, bonding, rivet bonding, and bolt bonding. It is known to do.
[0003]
First, the cold welding method is a method in which two metal members are pressed and joined to each other in a cold state (room temperature state) without heating. In addition, the hot welding method is a method in which the two metal members are heated to a high temperature and joined together by pressure welding in order to facilitate joining. As a result, the two metal members are fused in the vicinity of the joint surface, and an intermetallic compound is produced in part, thereby forming a strong bonded body.
[0004]
However, in the cold pressure welding method and the hot pressure welding method, since it is necessary to apply a large surface pressure to the metal member, it is difficult to form a clad plate made of a thick plate member or a wide member. Further, a surface treatment for cleaning the joint surface is necessary. Furthermore, when a brittle intermetallic compound grows in the vicinity of the joint surface, processing becomes difficult, and when atomic vacancies grow, joint strength decreases. Further, when the metal member is made of a brittle material, or when the two metal members are made of different materials having a large difference in plastic deformability, joint failure occurs. Furthermore, in the hot welding method, when the difference in thermal expansion between the two metal members is large, the combined body may be warped.
[0005]
In addition, the explosive bonding method is a method of joining two metal members in a vacuum state by exploding the explosive. However, since explosives are used, the danger is high and the energy consumption is low. It gets bigger. Further, when the metal member is made of a brittle material, the metal member is cracked by an impact caused by an explosion. In addition, loud explosions can cause noise problems.
[0006]
Furthermore, the diffusion method is a method in which a metal member is heated to diffuse one metal into the other metal and join, but when a brittle intermetallic compound grows, processing becomes difficult and atomic vacancies also occur. As the thickness grows, the bonding strength decreases. Further, when the metal member is heated, an oxide film is likely to be generated on the bonding surface, and when the oxide film grows, a bonding failure occurs. Further, when the difference in thermal expansion between the two metal members is large, the combined body may be warped.
[0007]
In view of this, there has been proposed a joining method for joining two metal members by plastically deforming a protruding portion formed on one metal member and filling a groove formed on the other metal member (Japanese Patent Application Laid-Open (JP-A)). 2000-311932 gazette and Japanese Patent Publication No. 57-46931 gazette).
[0008]
As a result, the two metal members can be firmly bonded without causing problems in the joining method such as the cold welding method, the hot welding method, the explosive bonding method, and the diffusion method.
[0009]
[Problems to be solved by the invention]
However, in the conventional coupling method, a large force is applied to the protrusion formed on the metal member to cause plastic deformation. Therefore, since the apparatus used for coupling | bonding needs to generate | occur | produce a big force, it enlarges and the manufacturing cost will become high. In addition, the energy consumption of the device increases. And the cost of the conjugate | zygote formed with the said coupling | bonding method will also become high.
[0010]
The present invention solves the conventional problems, and presses the convex portion formed on one member against the cusp-shaped protrusion formed on the concave portion formed on the other member to cause plastic flow, It is an object to provide a bonded body and a bonding method capable of firmly bonding a plurality of members by an easy operation without using special equipment and without consuming a large amount of energy. .

The peak protrusion is fixed to the bottom surface. Is.

[0034]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0035]
FIG. 1 is a cross-sectional view showing a joined body in the first embodiment of the present invention, and FIG. 2 is a perspective view showing a base material and a joined material before joining in the first embodiment of the present invention.
[0036]
In the figure, reference numeral 10 denotes a combined body composed of a base material 11 in which a concave groove 13 as a concave portion is formed and a binding material 21 in which a rectangular ridge 23 as a convex portion is formed. Here, the base material 11 and the binding material 21 have a substantially rectangular parallelepiped shape, as shown in FIG. The concave groove 13 is formed on a surface 12 as a concave forming surface facing the binding material 21 of the base material 11 so as to extend in the longitudinal direction of the base material 11, and has a narrow inlet 14 and a wide width. It consists of a back part 15. Further, at the center portion of the bottom surface 16 of the groove 13, a pointed ridge 17 is formed as a pointed protrusion extending in the same direction as the groove 13. That is, the concave groove 13 in the present embodiment has a Y-shaped cross-sectional shape as shown in FIGS. The pointed ridges 17 are formed integrally with the base material 11.
[0037]
On the other hand, as shown in FIG. 2, the rectangular ridges 23 are formed so as to extend in the longitudinal direction of the bonding material 21 on a surface 22 as a protrusion forming surface facing the base material 11 of the bonding material 21. Is done. Here, in the state before joining, as shown in FIG. 2, the width of the rectangular ridge 23 is constant and slightly narrower than the width of the inlet 14 of the concave groove 13. The rectangular ridges 23 are formed integrally with the binding material 21.
[0038]
And when the said base material 11 and the coupling | bonding material 21 are combined, if the said rectangular protruding item | line 23 is inserted in the ditch | groove 13, the flat front-end | tip 24 of the said rectangular protruding item | line 23 will be the said pointed protruding item | line 17 1 and is deformed by causing plastic flow, and the vicinity of the tip of the rectangular ridge 23 has a shape branched to both sides of the ridge 17 as shown in FIG. It enters the inner part 15 of the concave groove 13. As a result, the rectangular ridge 23 in the present embodiment has a substantially Y-shaped cross-sectional shape as shown in FIG. Therefore, the base material 11 and the binding material 21 are combined to form the combined body 10. The positional relationship between the base material 11 and the binding material 21 may be reversed. For example, the binding material 21 may be positioned on the upper side and the base material 11 may be positioned on the lower side. Further, the base material 11 and the binding material 21 may be arranged side by side or may be in an oblique positional relationship.
[0039]
Here, the material of the base material 11 is, for example, an iron alloy such as an aluminum alloy, steel, stainless steel, or cast iron, a copper alloy such as a magnesium alloy or brass, or a metal such as gold or silver. It may be ceramics such as alumina or silicon nitride. The material of the binder 21 is, for example, an iron alloy such as aluminum alloy, steel, stainless steel, cast iron, a copper alloy such as magnesium alloy or brass, or a metal such as gold or silver. It may be a resin such as plastic.
[0040]
The combination of the base material 11 and the binding material 21 is a combination in which the base material 11 is harder than the binding material 21, that is, the base material 11 is relatively hard. Any combination is possible as long as the combination 21 is made of a relatively soft material. In the present embodiment, the base material 11 is an iron alloy, more specifically, S45C defined in JIS, and the binding material 21 is an aluminum alloy, more specifically, A1050 defined in JIS. is there.
[0041]
In the present embodiment, when the combined body 10 is configured, the flat tip 24 of the rectangular ridge 23 formed on the bonding material 21 is pressed against the peak 18 of the ridge 17 formed on the base material 11. Then, it deforms by causing plastic flow, and the vicinity of the tip of the rectangular ridge 23 is branched to both sides of the pointed ridge 17 and enters the inner portion 15 of the groove 13. Therefore, the base material is such that the flat tip 24 of the rectangular ridge 23 formed on the bonding material 21 is pressed against the peak 18 of the peak ridge 17 formed on the base material 11 to cause plastic flow. 11 material is required to be harder than the material of the binder 21.
[0042]
In addition, the combination of the material of the base material 11 and the binding material 21 is such that the material of the base material 11 is the material of the binding material 21 only when the base material 11 and the binding material 21 are joined. Any combination may be used as long as it is harder, and any combination may be used before and after bonding.
[0043]
Therefore, when the base material 11 and the binding material 21 are the same material, only the binding material 11 may be heated and softened when the base material 11 and the binding material 21 are bonded. In this case, when the base material 11 and the binding material 21 are joined, the binding material 21 is relatively softer than the base material 11. Therefore, when the flat tip 24 of the rectangular ridge 23 formed on the bonding material 21 is pressed against the peak 18 of the peak ridge 17 formed on the base material 11, it causes plastic flow and deforms. And the front-end | tip vicinity part of the said rectangular protruding item | line 23 becomes the shape branched to the both sides of the peak protruding item | line 17, and since it approachs into the back part 15 of the said groove 13, the base material 11 and the binding material 21 are couple | bonded. The
[0044]
Furthermore, if the material of the base material 11 becomes harder than the material of the binding material 21 when the binding material 11 is heated and softened, the material of the base material 11 is higher than the material of the binding material 21 at room temperature. A combination that is soft may be used.
[0045]
Next, the deformation state of the binding material in the present embodiment will be described in detail.
[0046]
FIG. 3 is a first diagram showing a deformed state of the binder in the first embodiment of the present invention, and FIG. 4 is a second diagram showing a deformed state of the binder in the first embodiment of the present invention. is there.
[0047]
First, the binding material 21 is moved upward from the state shown in FIG. 2, and the rectangular ridge 23 is made to enter the inlet 14 of the concave groove 13 of the base material 11. In this case, it is sufficient that the base material 11 and the binding material 21 move in a relatively approaching direction, and the base material 11 may be moved downward. In the present embodiment, the base material 11 The case where 11 is fixed and the binding material 21 is moved upward will be described.
[0048]
And if the front-end | tip 24 of the said rectangular protruding item | line 23 further approachs toward the back | inner part 15 from the inlet 14 of the said recessed groove 13, the peak protruding item | line 17 formed in the center part of the bottom face 16 of the said recessed groove 13 will be shown. It is pressed against the peak 18. Here, when the binding material 21 is further moved upward, in the vicinity range 19 of the portion where the tip 24 of the rectangular ridge 23 contacts the peak 18, the peak 18 is moved as shown in FIG. The plastic flow that originates occurs. In addition, plastic flow does not occur in the portion of the rectangular ridge 23 other than the vicinity range 19 of the portion in contact with the peak 18. Thus, since the range where the plastic flow in the rectangular ridge 23 occurs is narrow, the plastic flow can be caused by moving the binder 21 with a slight force.
[0049]
Subsequently, when the binding material 21 is further moved upward, as shown in FIG. 4, in the vicinity range 19 of the portion where the rectangular ridge 23 contacts the peak 18, the peak 18 continues to be the starting point. However, plastic flow does not occur in the portion of the rectangular ridge 23 other than the vicinity range 19 of the portion in contact with the peak 18. And the front-end | tip vicinity part of the said rectangular protruding item | line 23 branches to the both sides of the peak protruding item | line 17, and penetrates into the inner part 15 of the said groove 13. Even in the state shown in FIG. 4, since the range in which the plastic flow in the rectangular ridges 23 occurs is narrow, the binder 21 can still be moved with a slight force, and the vicinity of the tip of the rectangular ridges 23 is sharpened. The head ridges 17 can be branched on both sides.
[0050]
Subsequently, when the binding material 21 is further moved upward, as shown in FIG. 1, the surface 12 on which the concave groove 13 is formed in the base material 11 and the rectangular ridges 23 in the binding material 21 are formed. The surfaces 22 are in contact with each other and are in close contact with each other. Further, the vicinity of the tip of the rectangular ridge 23 branches to both sides of the pointed ridge 17, enters the inner portion 15 of the groove 13, and contacts the bottom surface 16. As a result, the rectangular ridge 23 has a substantially Y-shaped cross-sectional shape and is fitted into the concave groove 13, so that the base material 11 and the binding material 21 are combined, and the combined body 10 is Composed.
[0051]
As shown in FIG. 1, there is a gap 27 between the deepest portion of the back portion 15, that is, between both side portions of the bottom surface 16 and the vicinity of the tip of the rectangular ridge 23. Will occur. The size of the gap 27 can be adjusted by adjusting the size of the cross-sectional area of the groove 13 and the cross-sectional area of the rectangular ridge 23 in a state before the coupling as shown in FIG. That is, if the cross-sectional area of the groove 13 is made larger than the cross-sectional area of the rectangular ridge 23, the gap 27 becomes large, and if the cross-sectional area of the groove 13 is the same as the cross-sectional area of the rectangular ridge 23. The gap 27 disappears.
[0052]
Further, diffusion bonding may occur in a portion where the side surface of the groove 13 and the side surface of the rectangular ridge 23 are strongly pressed against each other. For example, aluminum and copper are likely to cause diffusion bonding even at low temperatures. Therefore, when one of the base material 11 and the binding material 21 is made of an aluminum alloy and the other is made of a copper alloy, it is considered that diffusion bonding occurs. Also, when the binder 21 is heated and softened, the temperature becomes high, and diffusion bonding is likely to occur. As described above, when diffusion bonding occurs, the concave groove 13 and the rectangular ridge 23 are firmly bonded, and thus the bonding between the base material 11 and the bonding material 21 becomes strong.
[0053]
The degree of sharpness of the peak 18 of the peak ridge 17, that is, the central angle of the peak 18 can be appropriately changed.
[0054]
FIG. 5 is a first view showing the central angle of the peak formed in the base material in the first embodiment of the present invention, and FIG. 6 is formed in the base material in the first embodiment of the present invention. FIG. 7 is a second diagram showing the central angle of the peak, and FIG. 7 is a third diagram showing the central angle of the peak formed on the base material in the first embodiment of the present invention.
[0055]
In FIG. 5, the angle of the central angle of the peak 18 of the peak ridge 17 is 60 degrees, and the inclination angle of the side surface of the back portion 15 is equal to the inclination angle of the side surface of the peak ridge 17. In FIG. 6, the angle of the central angle of the peak 18 of the peak ridge 17 is 90 degrees, and the inclination angle of the side surface of the back portion 15 is the inclination angle of the side surface of the peak ridge 17. equal. In FIG. 7, the angle of the central angle of the peak 18 of the peak ridge 17 is 120 degrees, but the inclination angle of the side surface of the back portion 15 is the side surface of the peak ridge 17 in FIG. 5. Is equal to the inclination angle.
[0056]
The degree of sharpness of the cusp 18 of the ridge 17, that is, the central angle of the cusp 18 and the inclination angle of the side surface of the back part 15 are not limited to the examples shown in FIGS. It can be arbitrarily changed in consideration of the material of the base material 11 and the binding material 21.
[0057]
Moreover, the cross-sectional shape of the inlet 14 of the concave groove 13 can also be changed as appropriate.
[0058]
FIG. 8 is a first diagram showing another shape of the entrance of the concave groove formed in the base material in the first embodiment of the present invention, and FIG. 9 is a diagram of the base material in the first embodiment of the present invention. It is a 2nd figure which shows the other shape of the entrance of the formed ditch | groove.
[0059]
In FIG. 8, the width of the back side portion 14b of the inlet 14 of the concave groove 13 is constant, but the front portion 14a is a curved surface with R (R), and the width becomes narrower as it approaches the back side portion 14b. It has become. Thus, when the rectangular ridge 23 of the binding material 21 is inserted into the groove 13, the rectangular ridge 23 is recessed even if there is a deviation in the relative position or angle between the rectangular ridge 23 and the groove 13. It can be smoothly inserted into the groove 13. In addition, the magnitude | size of R, ie, a radius, can be determined suitably, for example, the whole inlet 14 may be a curved surface. Further, the front portion 14a may be a tapered inclined surface instead of a curved surface.
[0060]
In FIG. 9, the inlet 14 of the concave groove 13 is a tapered inclined surface, and the width becomes narrower as it approaches the inner part 15. Thus, when the rectangular ridge 23 of the binding material 21 is inserted into the groove 13, the rectangular ridge 23 is recessed even if there is a deviation in the relative position or angle between the rectangular ridge 23 and the groove 13. It can be smoothly inserted into the groove 13. The taper angle can be determined as appropriate, and the range of the inclined surface can be determined as appropriate.
[0061]
In addition, the cross-sectional shape of the rectangular ridge 23 of the binding material 21 can also be changed as appropriate.
[0062]
FIG. 10 is a first view showing another shape of the rectangular ridge formed on the binding material in the first embodiment of the present invention, and FIG. 11 is formed on the binding material in the first embodiment of the present invention. FIG. 12 is a third diagram showing another shape of the rectangular ridge formed on the binding material in the first embodiment of the present invention. .
[0063]
In FIG. 10, the width of the rectangular ridge 23 of the binding material 21 is constant, but both side ends 24 a of the tip 24 are curved surfaces with R, and the width of the flat portion of the tip 24 is the width of the rectangular ridge 23. It is narrower than the width of the side surface 23b. As a result, when the rectangular ridges 23 of the binding material 21 are inserted into the concave grooves 13 of the base material 11, even if there is a deviation in the relative position or angle between the rectangular ridges 23 and the concave grooves 13, The strip 23 can be smoothly inserted into the concave groove 13. In addition, the magnitude | size of R, ie, a radius, can be determined suitably. Furthermore, both side ends 24a of the tip 24 can be formed as tapered inclined surfaces instead of curved surfaces.
[0064]
Further, in FIG. 11, the entire side surface 23 b of the rectangular ridge 23 is a tapered inclined surface, and the width becomes narrower as it approaches the tip 24. Thus, when the rectangular ridge 23 of the binding material 21 is inserted into the groove 13, the rectangular ridge 23 is recessed even if there is a deviation in the relative position or angle between the rectangular ridge 23 and the groove 13. It can be smoothly inserted into the groove 13. The taper angle can be determined as appropriate, and the range of the inclined surface can be determined as appropriate.
[0065]
Further, in FIG. 12, a notch 24 b is formed in the flat portion of the tip 24 of the rectangular ridge 23. The notch 24 b is a minute V-shaped recess, notch or groove, and is formed at a position corresponding to the peak 18 of the peak ridge 17 in the base material 11. The depth and angle of the notch 24b can be determined as appropriate. For example, the depth of the notch 24b can be about 3 mm, and the angle can be about 60 degrees. It is desirable that the angle of the notch 24b is substantially the same as the central angle of the peak 18 of the corresponding peak ridge 17.
[0066]
In this way, by forming the notch 24b in the flat portion of the tip 24 of the rectangular ridge 23, the tip 24 of the rectangular ridge 23 is pressed against the tip 18 of the pointed ridge 17, and plastic flow occurs. At this time, plastic flow easily occurs from the portion of the notch 24b, and the tip 24 of the rectangular ridge 23 easily branches to both sides, so that the binder 21 can be moved with a very slight force.
[0067]
Further, the material of the pointed ridges 17 in the base material 11 can be different from the material of other parts of the base material 11.
[0068]
FIG. 13 is a first diagram showing the configuration of the base material in the first embodiment of the present invention, and FIG. 14 is a second diagram showing the configuration of the base material in the first embodiment of the present invention.
[0069]
In FIG. 13, the pointed ridge 17 is formed separately from the base material main body 11a, and the bottom surface of the pointed ridge 17 is at the center of the bottom surface 16 of the groove 13 in the base material main body 11a. , Glued and fixed by an adhesive. The adhesive may be made of a resin such as an epoxy resin, or may be made of a metal such as a solder or a brazing filler material.
[0070]
As a result, the base material main body 11a having the groove 13 is formed of a soft material, only the pointed ridge 17 is formed of a hard material, and the pointed ridge 17 is fixed to the bottom surface 16 of the groove 13. can do. For example, after forming the base material main body 11a from a soft material having good workability, the sharp protrusion 17 made of a hard material is fixed, so that the processing is easy and the rectangular protrusion of the binder 21 is formed. Thus, the base material 11 having the pointed protrusions 17 having a hardness sufficient to cause plastic flow in 23 can be obtained. Further, for example, the base material body 11a is formed of a material that is likely to cause diffusion bonding with the binding material 21, and then the pointed protrusions 17 made of a hard material are fixed, whereby the base material 11 and the binding material 21 are fixed. Bonding can be strengthened.
[0071]
Further, in FIG. 14, the pointed ridge 17 formed separately from the base material main body 11 a is fitted into the fitting recess 16 a formed in the bottom surface 16 of the concave groove 13 in the base material main body 11 a, The bottom surface 16 is fixed. In this case, since a part of the peak ridge 17 is fitted into the fitting recess 16 a, the peak ridge 17 is firmly fixed to the bottom surface 16. Further, the bottom surface of the ridges 17 may be adhered with an adhesive, or the adhesive may be omitted.
[0072]
Furthermore, the cross-sectional shape of the groove 13 can be changed as appropriate.
[0073]
FIG. 15 is a first view showing another shape of the groove formed in the base material in the first embodiment of the present invention, and FIG. 16 is formed in the base material in the first embodiment of the present invention. FIG. 17 is a second view showing another shape of the recessed groove, and FIG. 17 is a third view showing another shape of the recessed groove formed in the base material in the first embodiment of the present invention.
[0074]
In FIG. 15, the cross-sectional shape of the groove 13 is substantially V-shaped, and the shape is such that the inlet 14 in the substantially Y-shaped groove 13 shown in FIGS. 1 to 7 is omitted. In this case, the peak 18 of the peak ridge 17 is close to the surface 12 of the base material 11. In addition, in FIG. 16, the cross-sectional shape of the concave groove 13 has a shape in which the side wall of the back portion 15 of the concave groove 13 shown in FIGS. In this case, the bottom surface 16 of the concave groove 13 shown in FIGS. 1 to 7 is omitted. Further, in FIG. 17, the cross-sectional shape of the concave groove 13 is such that the inlet 14 of the concave groove 13 shown in FIG. 16 is omitted.
[0075]
In the present embodiment, the case where the concave portion is a groove has been described. However, the concave portion is not necessarily a groove, and may be a shape such as a hole or a hollow. Good. In this case, the convex portion also has a shape like a corresponding projection.
[0076]
Thus, in the present embodiment, it is formed on the base material 11 made of a relatively hard material, is composed of the narrow inlet 14 and the wide back portion 15, and has a pointed ridge at the center of the bottom surface 16. A rectangular ridge 23 of a binding material 21 made of a relatively soft material is inserted into the groove 13 provided with 17. Then, the rectangular ridge 23 causes plastic flow starting from the peak 18 in a vicinity range 19 of a portion where the rectangular ridge 23 contacts the peak 18 of the peak ridge 17. 13, the coupling material 21 is coupled to the base material 11 to form the coupled body 10.
[0077]
Therefore, since the range in which plastic flow occurs in the rectangular ridges 23 is narrow, the binding material 21 can be moved with a slight force, and the vicinity of the tip of the rectangular ridges 23 is branched to both sides of the pointed ridges 17. be able to. Therefore, it is possible to easily form the joined body 10 made of different materials without applying special equipment by applying a slight force and consuming a little energy.
[0078]
In addition, any combination may be used as long as the base material 11 is made of a relatively hard material and the bonding material 21 is made of a relatively soft material, and thus the base material 11 made of various materials. And the binding material 21 can be combined.
[0079]
Furthermore, as long as the binder 21 can be heated and softened, the binder 21 and the base material 11 may be the same material, or the binder 21 is a relatively hard material at room temperature. The combination consisting of may be sufficient.
[0080]
Next, a second embodiment of the present invention will be described. The description of the same structure and the same operation as those in the first embodiment will be omitted.
[0081]
FIG. 18 is a perspective view showing a base material and a bonding material before bonding in the second embodiment of the present invention.
[0082]
In the present embodiment, the base material 11 has a plate shape extending in the lateral direction in the figure, and a plurality of, for example, four concave grooves 13 are formed. On the other hand, the binder 21 also has a plate shape extending in the lateral direction in the figure, and a plurality of, for example, four rectangular ridges 23 are formed. The other points are the same as in the first embodiment.
[0083]
Then, the plate-shaped base material 11 and the binding material 21 are joined by being fitted into the four concave grooves 13 corresponding to the four rectangular ridges 23, and the opposing surfaces 12 and 22 are brought into close contact with each other. Thus, a clad plate is formed.
[0084]
As described above, in the present embodiment, the plate-shaped base material 11 in which the plurality of concave grooves 13 are formed and the plate-shaped bonding material 21 in which the plurality of rectangular ridges 23 are formed are combined to face each other. By bringing the surfaces 12 and 22 into close contact with each other, a clad plate can be easily formed without using special equipment and consuming a large amount of energy.
[0085]
Next, a third embodiment of the present invention will be described. The description of the same structure and the same operation as those of the first and second embodiments will be omitted.
[0086]
FIG. 19 is a cross-sectional view showing the shape of the pointed ridge formed on the base material in the third embodiment of the present invention.
[0087]
In the present embodiment, a plurality of pointed ridges 17 are formed on the bottom surface 16 of the groove 13 of the base material 11.

[0090]
In the present embodiment, a method for forming a recess having a pointed protrusion on a base material will be described. The concave groove 13 as the concave portion in the first to third embodiments can be formed by machining such as electric discharge machining, but in the present embodiment, it is formed by plastic working.
[0091]
First, as shown in FIG. 20A, the pressing portion 52 of the drilling tool 51 is pressed against the recess forming surface 12 of the base material 11. Here, the pushing portion 52 has a shape extending in a direction perpendicular to the drawing in order to form a concave groove. In addition, the pushing portion 52 is formed with a concave portion 53 for forming a pointed ridge. In this case, the drilling tool 51 is pressed against the recess forming surface 12 of the base material 11 until the pressing portion 52 is pressed into the base material 11 by a predetermined amount.
[0092]
As a result, the concave groove 13 including the pointed ridge 17 is formed in the base material 11. In this case, as shown in FIG. 20B, the cross-sectional shape of the concave groove 13 is such that the widths of the inlet and the back are substantially equal. Moreover, the recess forming surface 12 is curved.
[0093]
Therefore, the flat pressing surface 56 of the pressing tool 55 is pressed against the recess forming surface 12 of the base material 11. As a result, as shown in FIG. 20C, the cross-sectional shape of the concave groove 13 is such that the inlet is narrow and the back is wide. Further, the recess forming surface 12 is also corrected and becomes flat. Thereby, the concave groove 13 having a predetermined cross-sectional shape can be easily formed in the base material 11 by plastic working.
[0094]
The shape of the drilling tool 51 can be determined as appropriate in accordance with the shape of the recess formed in the base material 11. For example, the pushing portion 52 of the drilling tool 51 has a shape as shown in FIG. In this case, a recess 53 for forming the peaked ridge 17 is formed so as to extend in the longitudinal direction of the push-in portion 52.
[0095]
Further, for example, when the recess formed in the base material is not a recess but a cylindrical recess, a drilling tool having a pushing portion 52 having a shape as shown in FIG. 21B can be used. . In this case, the pushing portion 52 has a substantially cylindrical shape, and is formed with a recess 53 for forming a pointed projection.
[0096]
Furthermore, rolling can be performed as plastic working. In this case, in order to form the concave groove 13 continuously by rolling the base material 11, as shown in FIG. 22 (a) and FIG. 22 (b), a rolling roll 57 having a flange 58 is provided. use. In the figure, the number of the collars 58 is three, but can be selected as appropriate. In addition, FIG.22 (b) is A arrow view of Fig.22 (a). In addition, a recess 59 for forming the peaked ridge 17 is formed on the periphery of the flange portion 58.
[0097]
Then, the rolling roll 57 is rolled while being pressed against the recess forming surface 12 of the base material 11, thereby forming the groove 13 having the pointed ridges 17 in the base material 11 as shown in FIG. Is done. Subsequently, a rolling roll (not shown) that does not include the flange portion 58 and has a smooth peripheral surface is rolled while being pressed against the concave portion forming surface 12 of the base material 11, so that the cross-sectional shape of the concave groove 13 is as shown in FIG. As shown in 20 (c), the entrance is narrow and the back is wide. Further, the recess forming surface 12 is also corrected and becomes flat. Thereby, the concave groove 13 having a predetermined cross-sectional shape can be formed in the base material 11 by rolling. In this case, the base material 11 may be moved with respect to the rolling roll 57, or the rolling roll 57 may be moved with respect to the base material 11.
[0098]
The plastic working in the present embodiment may be hot working performed by heating the base material 11 or cold working performed without heating the base material 11. Whether it is hot working or cold working can be appropriately determined in consideration of the material of the base material 11, the drilling tool 51, the pressing tool 55, the performance of the device that drives the drilling tool 51 and the pressing tool 55, and the like.
[0099]
Next, a fifth embodiment of the present invention will be described. In addition, the description about what has the same structure as the said 1st-4th embodiment and the same operation | movement is abbreviate | omitted.
[0100]
FIG. 23 is a diagram showing a method of forming a combined body in the fifth embodiment of the present invention.
[0101]
In the present embodiment, the base material 11c and the binding material, which are formed by continuously rolling the raw material material 11a of the long base material and the raw material material 21a of the binding material to continuously form the concave grooves 13b and the rectangular ridges 23a, respectively. Next, a method of forming the clad plate 10a as a combined body by forming 21b and then continuously bonding the base material 11c and the binding material 21b will be described.
[0102]
First, a long binding material 21a having a cross-sectional shape as shown in FIG. 23A is rolled by rolls 31a and 31b as shown in FIG. ), A bonding material 21b having a plurality of rectangular ridges 23a formed on the surface 22a is continuously formed.
[0103]
On the other hand, a long base material 11a having a cross-sectional shape as shown in FIG. 23D is rolled by rolls 32a and 32b as shown in FIG. ), The base material 11b in which the plurality of grooves 13a are formed is continuously formed. In this case, the roll 32a or 32b has the same configuration as the rolling roll 57 in the fourth embodiment.
[0104]
Here, as for the cross-sectional shape of the said recessed groove 13a, the width | variety of an inlet_port | entrance and a back part is substantially equal, as FIG.23 (f) shows. Subsequently, the raw material 11b of the base material is rolled by rolls 33a and 33b as shown in FIG. 23 (g), and as shown in FIG. 23 (h), a plurality of grooves 13b are formed on the surface 12a. The base material 11c formed in the above is continuously formed. Here, as shown in FIG. 23 (h), the cross-sectional shape of the concave groove 13b is such that the inlet is narrow and the back is wide.
[0105]
Then, as shown in FIG. 23 (i), the binding material 21b and the base material 11c are pressed against each other by the rolls 34a and 34b with the surface 22a and the surface 12a facing each other. Then, the clad plate 10a is continuously formed by fitting into the concave grooves 13b corresponding to the respective rectangular ridges 23a and bringing the surface 22a and the surface 12a into close contact with each other.
[0106]
Thus, in the present embodiment, the base material in which the long base material 11a and the binding material 21a are rolled to continuously form the concave grooves 13b and the rectangular ridges 23a, respectively. 11c and the binder 21b are formed. Subsequently, the base material 11c and the binding material 21b are pressed against each other by the rolls 34a and 34b. Then, the rectangular ridges 23a are fitted into the concave grooves 13b, and the surfaces 22a and 12a are brought into close contact with each other to form the clad plate 10a continuously.
[0107]
Therefore, the clad plate 10a can be continuously formed, and the throughput of the production process of the clad plate 10a is improved. Note that the surface 22a and the surface 12a are not necessarily in close contact with each other, and in this case, the method in the present embodiment may be applied to form a combined body in a fifth embodiment to be described later. .
[0108]
Next, a sixth embodiment of the present invention will be described. In addition, the description about what has the same structure as the said 1st-5th embodiment and the same operation | movement is abbreviate | omitted.
[0109]
FIG. 24 is a cross-sectional view showing a combined body in the sixth embodiment of the present invention.
[0110]
In the present embodiment, the height dimension of the rectangular ridge 23 formed on the surface 22 of the bonding material 21 is considerably larger than the depth dimension of the groove 13 formed on the surface 12 of the base material 11.

And when this rectangular protruding item | line 23 was fitted to the ditch | groove 13, and the coupling body 10 was formed, as shown in the figure, the surface 22 of the coupling | bonding material 21 and the surface 12 of the base material 11 left | separated. It becomes a state.
[0111]
Thereby, a space 25 having a closed cross section is formed between adjacent rectangular ridges 23. Since the space 25 is continuous in the longitudinal direction of the combined body 10, that is, the direction perpendicular to the paper surface of FIG. 24 and has a closed cross section, the space 25 serves as a flow path for circulating a fluid such as gas or liquid. Can be used.
[0112]
For example, warm water can be circulated in the space 25 so that the combined body 10 can be used as a radiator for room heating, or a refrigerant can be circulated in the space 25 to cool the combined body 10 to a refrigerator or the like. It is also possible to use a combined vessel 10 as a furnace wall of a combustion furnace by circulating water or steam in the space 25.
[0113]
The cross-sectional area of the space 25 can be changed as appropriate by changing the height dimension and the interval of the rectangular ridges 23.
[0114]
Thus, in the present embodiment, the bonded body 10 is in a state where the surface 22 of the bonding material 21 and the surface 12 of the base material 11 are separated from each other.

In this case, only the vicinity of the rectangular convex shape 35 that is a portion that functions as a binding material when the unit members 31 are bonded to each other is heated. Thereby, when the rectangular convex shape 35 of the other unit member 31 is fitted into the concave groove 34 of one unit member 31, the rectangular convex shape 35 is relatively softer than the concave groove 34. For this reason, when the flat tip of the rectangular ridge 35 is pressed against the peak of the ridge formed in the groove 34, it causes plastic flow and deforms. And since the front-end | tip vicinity part of the said rectangular protruding item | line 35 becomes the shape branched on the both sides of the pointed protruding item | line and it penetrates into the back part of the said ditch | groove 34, adjacent unit members 31 are couple | bonded.
[0119]
Thus, in this Embodiment, the unit member 31 adjacent can be couple | bonded and the coupling body 36 can be formed. Therefore, for example, when the unit member 31 is a strip-shaped plate member, a wide-area plate-shaped member suitable for a wall or a floor can be easily formed as the combined body 36.

It is also possible to form the concave grooves 13 on both surfaces of the single base material 11 and to connect the binding material 21 to both sides of the base material 11.
[0128]
Thus, in the present embodiment, the base materials 11-1 and 11-2 are bonded to both sides of the bonding material 21 to form the sandwich-shaped bonded body 10. Therefore, for example, when the binder 21 is a resin plate-like member and the base materials 11-1 and 11-2 are steel plate-like members, a vibration-absorbing steel plate can be manufactured.
