In each embodiment of following explanation, exemplify the material of each component, but in whole embodiments each
The material of component is not limited to the content especially illustrated, and the present invention can be applied to arbitrary material.
(first embodiment)
Reference picture 1A to Fig. 2 D is to steel (first component) 10 is connect with the ca(u)lk engagement of aluminum pipe (second component) 20
Conjunction method is illustrated.
As shown in Figure 1A, steel 10 is made up of high strength steel, and in the shape of channel-style.Steel 10 possesses bottom
Wall (Part I) 11, distinguish from bottom wall 11 towards two side walls 12,13 of extension above vertical and from two side walls 12,13
The upper wall 14 that outside extends in the horizontal direction.The hole portion (the first hole portion) 15 that can be inserted for aluminum pipe 20 is provided with bottom wall 11.
Aluminum pipe 20 is made up of aluminium alloy, is circle in hollow form and section, is extended along axis L directions.Axis L is passed through in aluminum pipe 20
The center of the hole portion 15 of the heart and steel 10.
As shown in Figure 1B, for aluminum pipe 20 and steel 10, become by the way that aluminum pipe 20 is expanded from inner side towards outside
Shape and in conquassation figure upside end 21, engaged with the ca(u)lk of hole portion 15 of steel 10.Hole portion 15 on steel 10
Shape and size, using the shape similar to the cross sectional shape of aluminum pipe 20, preferably in the scope that can be inserted for aluminum pipe 20
It is inside as far as possible small.
Steel 10 is engaged with the ca(u)lk of aluminum pipe 20 according to following order execution.
As shown in Fig. 2A to Fig. 2 D, steel 10 is engaged with the ca(u)lk of aluminum pipe 20 using rubber (elastomer) 30.
First, as Fig. 2A, aluminum pipe 20 is inserted in the hole portion 15 of steel 10, rubber is inserted in the inside of aluminum pipe 20
30, and it is arranged at decompressor 40.Wherein, can also by aluminum pipe 20 inside it inserted with the state of rubber 30 to hole portion 15
Insert.Decompressor 40 possesses tabletting 43 and bearing block 42.Tabletting 43 has flat lower surface, and compressed steel is pressed using lower surface
Part 10 or rubber 30 processed.Bearing block 42 has flat upper surface, and steel 10 or rubber 30 are loaded in upper surface.
Rubber 30 uses the total length rubber longer than aluminum pipe 20 in the cylindrical shape for the diameter that can be inserted to aluminum pipe 20.Thus, setting
In the state of, rubber 30 is partly protruded from the upper end of aluminum pipe 20.Therefore, when decompressor 40 start punching press and bearing block 42 with
Tabletting 43 close to when, rubber 30 is pressed at first.But, rubber 30 need not be protruded necessarily from the upper end of aluminum pipe 20,
Can be coplanar with the upper end of aluminum pipe 20 or it be accommodated in the inside of aluminum pipe 20.
Then, as Fig. 2 B, the external force of compression is assigned to rubber 30 along axis L directions using decompressor 40.It is right
In rubber 30, the size with axis L directions diminishes and the dimension enlargement of radial direction.So make rubber 30 from axis L towards outside
Elastic deformation (expansion), makes the enlargement deformation of aluminum pipe 20.Also, as Fig. 2 C, further compressed by using decompressor 40,
Make the further enlargement deformation of aluminum pipe 20, while bending and pressing the end 21 of upside in the figure of aluminum pipe 20 towards steel 10
Burst, and engaged with the ca(u)lk of steel 10.
After ca(u)lk engagement, as Fig. 2 D, the rubber 30 of compression stress of decompressor 40 is eliminated by the bullet of itself
Property power and return to original shape, easily can be removed from aluminum pipe 20.
According to this method, make the equably enlargement deformation of aluminum pipe 20 by making rubber 30 towards lateral expansion, office can be prevented
The deformation in portion, mitigates the load relative to each component 10,20.Because, utilize the rubber 30 compressed along axis L directions
The property equably expanded from inner side towards outside, can be such that aluminum pipe 20 equably deforms.Thus, it is possible to chimeric precision is improved,
And improve bond strength.In addition, being than electro-magnetic forming or the simple method of other processing methods.
Electro-magnetic forming can be only applied to conductive material, and cross sectional shape, size are also limited by used coil.With
This is relative, and this method is unrelated with material, also in the absence of the limitation related to cross sectional shape, size.Furthermore it is possible to use to rubber
30 apply the equipment of compression stresses to perform, therefore, without electrically setting for the capacitor that Large Copacity is needed as electro-magnetic forming
It is standby.
As previously discussed, according to this method, two components can be engaged, low cost and many materials can be simply performed
Change.Thus, as described above, beyond two parts of high strength steel and aluminium alloy, also can be relative to various materials
Component uses this method.It is same in the following embodiments.
On the material of the rubber 30 inserted towards the inner side of aluminum pipe 20, for example preferably use polyurethane rubber, neoprene,
Any one of CNR rubber (neoprene+nitrile rubber) or silicon rubber.In addition, the hardness of these rubber 30 is excellent in terms of Shore A
Elect more than 30 as.
It should be noted that the component inserted towards aluminum pipe 20 is not limited to rubber 30.For example, such as Fig. 3 A and Fig. 3 B institutes
Show, rubber 30 can also be replaced and the fluid-filled component 32 for being internally sealed with gas or liquid is used.As long as in addition, energy
It is enough to make the enlargement deformation of aluminum pipe 20 towards lateral expansion under compressive forces, component in addition can also be used.It is preferred that
For with compression stress correspondingly towards lateral expansion when the component that is equably deformed as rubber 30.
In addition, as shown in Figure 4A and 4B, the shape and chi of the hole portion 15 set in the bottom wall 11 of steel 10
