After formal bonding process finishes, will give prominence to material from basal component 2 excisions.
Figure 15 a and Figure 15 b mean the figure of the heat transfer plate 41 after the formal bonding process of present embodiment.Heat transfer plate 41 is formed with surface plasticity region W3 by bonding process.Because surface plasticity region W3 dwindles because of thermal contraction, therefore, heat transfer plate 41 may form in surperficial Za side the back-flexing of concavity.Particularly be shown in a～place, place j of surperficial Za of heat transfer plate 41, place a, the c of four jiaos of heat transfer plate 41, the bending of f, h have the tendency of remarkable performance.Place j represents the central place of heat transfer plate 41.
(5) correction process
In correction process, use to correct and to use throw G, from the back side Zb of basal component 2 stirring that rubs.Correction process is the operation of carrying out for the bending that elimination produces in above-mentioned bonding process.In the present embodiment, correction process comprises: the rectification friction agitating procedure that radiation wire ground rubs and stirs; And the bight friction agitating procedure that the bight of basal component 2 is rubbed and stirred.
As shown in Figure 16 a, in correcting friction agitating procedure, rub and stir and form and pass through the radial plastification of central place j ' region.; set the path that friction is stirred, make respectively connecting on the straight line of place a ' and place h ', be connected on the straight line of place d ' and place e ', be connected on the straight line of place f ' and place c ', be connected on the straight line of place g ' and place b ' the rub starting position (S of stirring of setting respectively m5, S m6, S m7, S m8) and end position (E m5, E m6, E m7, E m8), and the distance from each starting position to central place j ' is equated with the distance from central place j ' to each end position.
After setting the path of the friction stirring of correcting friction agitating procedure, rectification is pressed into each starting position with throw G, along each path (straight line), make to correct and move with throw G.In correcting friction agitating procedure, with the stirring that rubs of the bonding process amount of being pressed into about equally.As shown in Figure 16 b, plastification region, the back side W41～W44 forming in correcting friction agitating procedure expands in eight directions radially with respect to central place j '.
As shown in Figure 16 b, in bight friction agitating procedure, in each bight of the place of basal component 2 a ', place c ', place f ' and place h ', carry out the friction of emphasis and stir.That is, in formation, corresponding to one side 2a side in the bight of place a ', set the starting position S that friction is stirred m9and end position E m9, in another side 2b side, set the position S that turns back r9.Then, rectification is being pressed into starting position S with throw G m9and towards turning back position S r9after movement, make to correct with throw G at the position S that turns back r9turn back, and at end position E m9depart from.Also can carry out same operation in each bight of place c ', place f ' and place h '.Due to the agitating procedure that rubs by bight, can, to the correction process that particularly emphasis is carried out in the bight of crooked large basal component 2, therefore, can further improve the flatness of heat transfer plate 41.
In the present embodiment, in bight friction agitating procedure, correct and use the track of throw G to form the form formation of diagonal quadrature with each bight, but be not limited to this.Only need to consider the size of bight bending and suitably set the path that friction is stirred.In bight, the friction W47, back side, plastification region, the W45Yu back side, plastification region, the formed back side of the agitating procedure W46Yu back side, plastification region plastification region W48 forms point symmetry with respect to central place j ' respectively.By this, the bending of surperficial Za side and the back side Zb side of heat transfer plate 41 can be eliminated evenly, thereby the flatness of heat transfer plate 41 can be improved.
(6) face cutting process
In face cutting process, use known end mill(ing) cutter etc. to carry out face cutting to the back side Zb of heat transfer plate 41.As shown in Figure 16 b, at the back side of heat transfer plate 41 Zb, produce to correct punching (not shown) with throw G, owing to being pressed into groove (not shown) that each throw produces and burr etc.Therefore,, by carrying out face cutting process, can make the back side Zb of heat transfer plate 41 form smoothly.In the present embodiment, as shown in figure 17, the thickness Ma of face machining sets for also larger than the thickness Wa of plastification region, back side W42.By this, owing to removing plastification region, back side W41～W44 of the back side Zb that is formed at basal component 2, therefore, can realize the homogeneity of the character of basal component 2.In addition, because plastification region, back side W42 etc. does not expose from back side Zb, so design etc. is also better.
In the present embodiment, the thickness of face machining is set for also larger than the thickness in plastification region, the back side, but is not limited thereto.The thickness of face machining for example also can be set for also larger than the length of correcting the stirring pin G2 that uses throw G.
In addition, in the present embodiment, use the rectification with stirring pin G2 to carry out correction process with throw G, but also can with throw, carry out correction process with the rectification without stirring pin G2.Owing to utilizing this throw, can make the degree of depth in plastification region, the back side shoal, therefore can reduce the thickness of face cutting.By this, because the part of face cutting is less, so the loss of basal component 2 tails off, and can reduce costs.
According to the 4th embodiment described above, even if the thermal contraction causing because of bonding process makes heat transfer plate 41 bendings, also the stirring that can rub by the back side Zb at basal component 2, eliminates the bending producing at surperficial Za, thereby can easily improve the flatness of heat transfer plate 41.That is, owing to being formed at plastification region, the back side W41 to W44 of the back side Zb of basal component 2, because of thermal contraction, dwindle, therefore, in the back side of heat transfer plate 41 Zb side, compression stress is from each bight side of basal component 2 towards central side effect.By this, in the formal formed bending of bonding process, be eliminated, can improve the flatness of heat transfer plate 41.
In addition, according to the 4th embodiment, due to docking section J3, the J4 of cover plate 42 and groove 43 to engage the once mobile stirring that rubs with throw F, therefore, compare with the first embodiment, can omit significantly operation formality.In addition, because the back side Zb to basal component 2 carries out bight friction agitating procedure, therefore can carry out the rectification of emphasis to crooked large bight particularly, can improve the flatness of heat transfer plate 41.

Heat transfer plate 61 shown in Figure 19 mainly comprises the cover plate 54 of pipe 53 and inaccessible groove for the thermal medium of the groove (not shown) that central authorities have the basal component 2 of peristome 52, the surperficial Za that is embedded at basal component 2 cuts out.
Thermal medium observes to overlook the inside that the criss-cross modes be hollow are embedded in basal component 2 with pipe 53.The peristome 52 that thermal medium is exposed to basal component 2 with pipe one end of 53 and the other end.From the thermal medium that comes across peristome 52, with one end of pipe 53, supply with heat, from the other end, hot type is gone out and transfer heat to basal component 2.
Cover plate 54 and the docking section of basal component 2 are to be engaged and with throw F, carried out the operation roughly the same with the 4th embodiment and rub to stir and engage by use.By this, at the surperficial Za of basal component 2, be formed with to overlook and be roughly the criss-cross surface plasticity of hollow region W60.
On the one hand, as shown in figure 20, the back side Zb of heat transfer plate 61 is identical with surperficial Za, is formed with to overlook to observe to be the criss-cross back side of hollow plastification region W61.The starting position S that friction in this correction process is stirred mand end position E mbe set in any point of basal component 2.In correction process, with the stirring that rubs of the roughly the same amount of being pressed into of bonding process.In addition, back side plastification region W61 is used to correct with throw G, with continuous track, rub stirring and form.
As the heat transfer plate 61 of the 6th embodiment, also can set the path that friction stirs so that be formed at respectively the surperficial Za of heat transfer plate 61 and the W60He back side, the surface plasticity region plastification region W61 of back side Zb forms roughly the same shape.By this bonding process and correction process, the shape that is formed at the surperficial Za side of heat transfer plate 61 and the plastification region of back side Zb side is roughly the same, therefore, can eliminate evenly the bending of heat transfer plate 61, thereby can improve flatness.
According to the 6th embodiment, the length of the track that the length of the track that the friction of carrying out in the surperficial Za side of basal component 2 is stirred and the friction that Zb side is carried out are overleaf stirred about equally, but form than engaging and use throw F also little owing to correcting with throw G, therefore, the degree of finish of correction process is also less than the degree of finish engaging by operation.
Correction process is not limited to the path of the friction stirring of above-mentioned the first embodiment to the six embodiments, and can set various paths for.The alternate manner in the path of below, the friction in correction process being stirred explains.

As described above, the track that correction process only need stir corresponding to the friction of the bonding process of carrying out at basal component 2 and suitably set the path that friction is stirred.
In description of the present embodiment, to basal component 2, be to overlook to observe to be foursquare example and to be described, but other shape also can.
The 7th embodiment
In the correction process of above-mentioned the first embodiment to the six embodiments, with correcting with throw G, the back side Zb of basal component 2 to be rubbed to stir, do crooked rectification, but be not limited thereto.In the correction process of the 7th embodiment, the bending moment being produced by tensile stress acts on the surperficial Za side of basal component 2 from the back side Zb of heat transfer plate 1 (basal component 2), thereby corrects the bending by the formed heat transfer plate 1 of above-mentioned bonding process.In the correction process of present embodiment, only need correct from the pushing of the following stated, impact correct and roller correct these three kinds of methods, choose any one kind of them above.
Figure 22 means the stereogram of the preparatory stage that the pushing of the 7th embodiment is corrected.Figure 23 means the side view that the pushing of the 7th embodiment is corrected, and Figure 23 a means the figure before pushing, and Figure 23 b represents the figure in pushing.Figure 24 means the top view of the pressing position that the pushing of the 7th embodiment is corrected.Figure 25 means the figure that the roller of the 7th embodiment is corrected, and Figure 25 a is stereogram, and Figure 25 b means the side view before pushing, and Figure 25 c means the side view in pushing.
In the correction process of the 7th embodiment, use the heat transfer plate 1 of the first embodiment to explain.
(pushing is corrected)
After carrying out bonding process with the main points identical with above-mentioned the first embodiment, remove the burr that stir generation because of friction, and as shown in figure 22, the back side Zb of heat transfer plate 1 overturning towards top, the central place j ' of Zb (with reference to Fig. 7 b) configures the first tabular auxiliary part T1 overleaf.And in the surperficial Za side of heat transfer plate 1 four jiaos, configure tabular the second auxiliary part T2, T2 and the 3rd auxiliary part T3, T3.That is, the second auxiliary part T2 and the 3rd auxiliary part T3 are disposed at both sides across the first auxiliary part T1.The first auxiliary part T1 to the three auxiliary part T3 push the member that becomes butt material or pedestal while correcting, and are also the members for fear of damage heat transfer plate 1.The first auxiliary part T1 to the three auxiliary part T3 are so long as the material softer than heat transfer plate 1 for example can be used aluminium alloy, vulcanie, plastics, timber.The first auxiliary part T1 to the three auxiliary part T3 only need be according to the mechanical characteristic of heat transfer plate 1 and crooked curvature, and setting can make heat transfer plate 1 correct crooked enough thickness towards the contrary side deflection of bending.
As shown in Figure 23 a and Figure 23 b, after each auxiliary part of configuration, use known pressing device P, from the back side Zb of heat transfer plate 1, press.The drift Pa of pressing device P is pressed against to the first auxiliary part T1, and presses with the pressing force of regulation.When utilizing pressing device P to exert pressure to heat transfer plate 1, as shown in Figure 23 a and Figure 23 b, the first auxiliary part T1 presses heat transfer plate 1 towards downside, the second auxiliary part T2 and the 3rd auxiliary part T3 press the both end sides of heat transfer plate 1 towards upside, so on heat transfer plate 1, effect has bending moment.Because this bending moment makes tensile stress, act on the surperficial Za side of heat transfer plate 1, therefore heat transfer plate 1 is protruded to deflection towards downside forcibly.
The pressing force of pressing device only need be done suitable setting according to the thickness of heat transfer plate 1 and material, as shown in Figure 23 b, preferably makes to protrude under the surperficial Za side direction of heat transfer plate 1, makes bending moment effect and produces tensile stress at surperficial Za.
In addition, in the present embodiment, as shown in figure 24, not only to central place j ', also can be to also pressing near the place b ' of the back side Zb of heat transfer plate 1, place d ', place e ' and place g '.Intermediate location on each limit of the back side Zb that comprises heat transfer plate 1 is that position H2～H5 of place b ', place d ', place e ' and place g ' configures the first auxiliary part T1, and utilizes pressing device P to press.By this, heat transfer plate 1 can be corrected evenly, and flatness can be further improved.
And in the present embodiment, the set positions of pushing is in five positions, but is not limited thereto, only need suitably set corresponding to the bending of the heat transfer plate 1 producing because of bonding process.
(impact and correct)
Then, impact is corrected and is explained.Approximate with pushing rectification owing to impacting rectification, so omit concrete diagram.So-called impact is corrected and is referred to such as utilizing the percussion tools such as hammer to correct resulting from the bending of heat transfer plate.Impact to correct except replace pressing device P with percussion tools such as hammers heat transfer plate 1 is impacted this point, all the other correct roughly the same with pushing.
In impacting rectification, after configuring auxiliary part in the same manner with pushing rectification, with reference to Figure 23 and Figure 24, from the back side Zb utilization of heat transfer plate 1, such as percussion tools such as plastic hammers, impact heat transfer plate 1.Due to when impacting heat transfer plate 1, the surperficial Za side generation tensile stress at heat transfer plate 1, therefore makes heat transfer plate 1 forcibly to downside deflection projectedly (with reference to Figure 23 b).By this, can correct the bending of heat transfer plate 1 and become smooth.In addition, identical with pushing rectification, impact as required position H2～H5 (with reference to Figure 24) of the back side Zb of heat transfer plate 1, thereby can correct evenly heat transfer plate 1.
Impact to correct with pushing and correct and compare, owing to having omitted the formality of preparing pressing device etc., therefore can easily carry out operation.In addition, impacting and correct because operation is easy, is therefore effective to little and thin heat transfer plate 1.And, after being preferably in and impact correcting and to finish, remove the burr that produce due to impact.In addition, as long as percussion tool can impact heat transfer plate 1, be not particularly limited its kind, but be preferably for example plastic hammer.
(roller rectification)
Then, roller is corrected and explained.After carrying out bonding process with the main points identical with the first embodiment, remove the burr that produce because of friction stirring, and as shown in Figure 25 a, the back side Zb of heat transfer plate 1 is overturn towards top, the first auxiliary part T1 of long plate shape is configured to central place j ' (with reference to Fig. 7 b) and the parallel longitudinal by back side Zb.And, the second auxiliary part T2 of long plate shape and the 3rd auxiliary part T3 are configured to edge and the parallel longitudinal in the surperficial Za side of heat transfer plate 1.That is, the second auxiliary part T2, the 3rd auxiliary part T3 are disposed at both sides across the first auxiliary part T1.
Then, at the upside of the first auxiliary part T1, configure orthogonally roller R1 with the first auxiliary part T1, at the downside of the second auxiliary part T2, the 3rd auxiliary part T3 and the second auxiliary part T2 and the 3rd auxiliary part T3, configure orthogonally roller R2.That is, as shown in Figure 25 b, heat transfer plate 1 upside with the state configuration protruded between roller R1, R2, via the first auxiliary part T1 to the three auxiliary part T3, by roller R1, R2, clamped.
The first auxiliary part T1 to the three auxiliary part T3 are the butt materials while carrying out roller rectification, are also the members of avoiding making heat transfer plate 1 damage.The first auxiliary part T1 to the three auxiliary part T3 for example, so long as than heat transfer plate 1 soft material also, can be used aluminium alloy, vulcanie, plastics, timber.
When roller R1, R2 close to each other and while bringing pressure to bear on heat transfer plate 1, as shown in Figure 25 b and Figure 25 c, the first auxiliary material T1 presses heat transfer plate 1 towards downside, the second auxiliary part T2 and the 3rd auxiliary part T3 press the both end sides of heat transfer plate 1 towards upside, therefore, there is bending moment to act on heat transfer plate 1.Because this bending moment makes tensile stress, result from the surperficial Za side of heat transfer plate 1, therefore, heat transfer plate 1 is protruded to deflection towards downside forcibly.
In addition,, as shown in Figure 25 a, when roller R1 is towards arrow α direction rotation, roller R2 during towards arrow β direction rotation, roller R1, R2 relatively move towards arrow γ direction (roller direction of transfer) with respect to heat transfer plate 1.In addition,, when roller R1 is towards arrow β direction rotation, roller R2 during towards arrow α direction rotation, roller R1, R2 relatively move towards arrow δ direction (roller direction of transfer) with respect to heat transfer plate 1.
Therefore, the position that acts on the bending moment of heat transfer plate 1 is followed this to relatively move and moves, so, to downside, protrude deflection to heat transfer plate 1 being forced to property of integral body.Therefore, by repeatedly carrying out this, relatively move and move back and forth, can correct gradually bending.And the first auxiliary part T1 to the three auxiliary part T3 only need set for and can make heat transfer plate 1 correct crooked enough thickness towards the contrary side deflection of bending according to the curvature of the mechanical characteristic of heat transfer plate 1 and bending.
In addition, also can, roller R1, R2 are carried out after correction process along longitudinal rotation of heat transfer plate 1, make roller R1, R2 along transverse rotation.That is, make the first auxiliary part T1 to the three auxiliary part T3 and laterally configuration abreast, and configure orthogonally roller R1, R2 with the first auxiliary part T1 to the three auxiliary part T3.Then, roller R1, R2 are moved back and forth in the horizontal.By this, can correct evenly heat transfer plate 1.
In addition, at this, to the back side Zb that makes heat transfer plate 1 towards on carry out detorsion operation and be described, but also can not overturn and make surperficial Za towards on carry out detorsion operation.Now, because each above-mentioned member of formation is symmetrical in table, therefore the description thereof will be omitted.
According to the 7th embodiment described above, even if the surperficial Za of heat transfer plate 1 is due to bonding process, thermal contraction makes heat transfer plate 1 bending, also can at the back side of basal component 2 Za, produce tensile stress by making bending moment effect, thereby can easily improve the flatness of heat transfer plate.
