Description
Technical field
The present invention relates to friction stirring connecting method and friction-stir conjugant, particularly, the present invention relates to following friction stirring connecting method and the friction-stir conjugant by adopting the method to be formed, this friction stirring connecting method comprises: hardware is coincided with one another; Make instrument compress a hardware, join another hardware to make this hardware in friction-stir engaging process.
Background technology
In the prior art, typically via adopting fusion weld, using the mechanical engagement of rivet or other parts or make the hardware be made up of the different metal material of such as iron and aluminium etc. be engaged with each other by other joint method.In the mechanical engagement using rivet or bolt, need rivet or other assembling parts for engaging, this causes undesirably, and cost increases, weight increases and other problem.Because these situations, as the method for jointing metal component, carry out friction-stir joint (FSW:FrictionStirWelding) in recent years.As shown in figure 12, friction-stir engages and comprises: make that hardware 101 and 102 coincides with one another, rotational engagement instrument 103 joining tool 103 is compressed a hardware 101 and make the softening frictional heat of this hardware 101 to produce and make this hardware 101 of joining tool 103 injection, make the rotatory force produced by instrument 103 stir this hardware 101 and another hardware 102 and make hardware experience Plastic Flow.Thus this hardware 101 and another hardware 102 is made to be engaged with each other.
In this friction stirring connecting method, the terminal part place engaged at friction-stir when puller 103 defines hole (hereinafter referred to as tooling hole) 104 ((b) and Figure 13 see Figure 12).When defining tooling hole 104, the interface 105 between this hardware 101 and another hardware 102 is exposed.In this case, if such as interface 105 is exposed to water, then can produce less desirable electrolytic etching (electrolyticcorrosion).Position residing when the terminal part that friction-stir engages refers to that friction-stir has engaged.Namely, when from one end to the other side carrying out friction-stir joint, terminal part refers to the position at other end place, and when carry out friction-stir joint to one end and this is engaged into that behavior returns to middle position further, instrument is pulled out at the position of this centre, the position of centre residing when terminal part finger has closed.
In addition, when by using friction-stir joint to make the component be made up of different metals (iron and aluminium) be engaged with each other, the interface between hardware is caused to create fragile intermetallic compound (such as Fe undesirably because of introducing a large amount of heat in the process of fusion weld

3), this problem causing bond strength to reduce.
In addition, when carrying out making the friction-stir of another metal 102 of the non-injection in the front end of instrument 103 engage (when the friction-stir carrying out making the front end of instrument 103 be retained in and do not arrive in a metal material 101 another metal material 103 engages), the front end of interface 105 and instrument 103 needs each other as much as possible close to increase bond strength.In this process, if the front end of instrument 103 is too near by interface 105, then instrument 103 can be pulled out when a hardware 101 is attached to instrument 103, and this causes the bottom of tooling hole 103 damaged and the terminal part of this hardware 101 is penetrated into another hardware 102 by tooling hole 104.If the interface between hardware 101 and 102 105 (part that iron and aluminium contact with each other) is exposed by the tooling hole 104 as through hole subsequently, then can there is electrolytic etching at the position of exposing, cause the reduction of bond strength.As mentioned above, though when do not make instrument 103 front end injection another metal material 102, in some cases interface 105 also can friction-stir engage terminal part place expose undesirably.In this case, if such as interface 105 is exposed to water, then electrolytic etching can be there is in interface.In addition, although principle makes the shorter bond strength of the distance between the front end of instrument 103 and interface 105 larger, run counter to ground with expectation, bond strength reduces undesirably.
Because these situations, propose the friction stirring connecting method of the friction stirring connecting method of such as patent document 1 and patent document 2 explanation etc.
In order to fill the through hole at the terminal part place that friction-stir engages, patent document 1 discloses: brief termination engages, then packing material is arranged in tooling hole, then again carries out friction-stir at this tooling hole place and engage air-tightness and the watertightness of improving the junction surface at terminal part place.
The friction-stir that patent document 2 discloses between the hardware be made up of different metal material engages, even if specifically disclose the terminal part place engaged at friction-stir arrange the surplus metal section of such as protuberance etc. and make the tooling hole when terminal part forms tooling hole also not become through hole, the interface between hardware is therefore prevented to expose or be subject to electrolytic etching.

Summary of the invention
The problem that invention will solve
But the method that patent document 1 illustrates has following problem:
Namely, the method that patent document 1 illustrates needs to carry out packing material to be arranged at after once performing friction-stir and engaging in the tooling hole at the terminal part place that friction-stir engages with the step that the step in fill tool hole and again carrying out engages.Therefore, step number is added undesirably.
The friction stirring connecting method that patent document 2 illustrates has following problem:
(1) the terminal part place owing to engaging at friction-stir is provided with surplus metal section, and the weight therefore being engaged the product produced by friction-stir increases undesirably.
(2) when use such as telescopic material (extruded material) etc., the metal material with homogeneous thickness patent document 2 can not be used to illustrate method.Therefore, the method has the low shortcoming of the free degree of Material selec-tion.
(3) distance between the front end of instrument and interface is being formed with the position of surplus metal section of tooling hole than except all the other positions director except this surplus metal section.On the other hand, known distance between the front end of instrument and interface is set as that little value can improve bond strength, and this distance is set as that large value can reduce bond strength.Therefore, in the method that patent document 2 illustrates, the bond strength of the interface in surplus metal section is less than the bond strength of the interface in the position except surplus metal section.Result, if import stress in the parts by using the method to engage, the position the closer to surplus metal section that then bond strength is relatively low more early produces breakage, crackle may be caused to produce from damaged part and proceed to other position gradually, water can enter the position of this breakage, therefore electrolytic etching occurs.
Because these situations achieve the present invention, the object of the present invention is to provide a kind of following friction stirring connecting method and friction-stir conjugant: this friction stirring connecting method in friction-stir engaging process, make the hardware be made up of different metal material be engaged with each other and the contact site preventing different hardwares to contact with each other exposes at junction surface, and provide a kind of following friction stirring connecting method and friction-stir conjugant especially: this friction stirring connecting method makes the bond strength at the terminal part place engaged at friction-stir with roughly equal at the bond strength at the position except terminal part, and special additional step need not be set or special structure is set in hardware, even if such as tooling hole is exposed to water also can prevent electrolytic etching, and this friction stirring connecting method is suitable for having the metal material of roughly homogeneous thickness.

Prevent the interface between hardware from exposing, do not need to arrange packing material or other parts after friction-stir engages.Namely, only engage relevant step to friction-stir just enough, the quantity of step can not increase.
Prevent interface from exposing, do not need for terminal part arranges surplus metal section.Thus weight can not increase.
Even if when use such as telescopic material etc., the material with homogeneous thickness, the interface between hardware also can be avoided to expose, hence improve the free degree of Material selec-tion.
Distance between the interface of the terminal part engaged with friction-stir due to the front end of instrument can be reduced to distance the shortest as far as possible, and the distance therefore between the front end of instrument and the interface of terminal part can be substantially equal to the distance at the position except terminal part.Thus, the bond strength of terminal part can be made to be substantially equal to the bond strength at the position except terminal part.Therefore, even if introduce stress in the conjugant by using the method to engage, be also difficult to breakage occur, this is because conjugant has roughly homogeneous, high bond strength on whole conjugant.Even if occur damaged, terminal part does not have the risk of premature breakage yet.Result, because the conjugant by using this method to engage can not be damaged, therefore water can not enter the interface between hardware, even if or also can not form when the terminal part that friction-stir engages contacts with the peripheral part of hardware the gap allowing water to enter, can electrolytic etching be avoided thus.
