Like this, stepped wall 31a, 51a(Fig. 8 of utilizing Width cylinder 33,53 square line 14 to be pressed on pedestal 31,51) after, by thickness direction cylinder 32,52 by pressing component 36,56 from the top side of pressing line 14, be formed at the stepped wall 36a of pressing component 36,56,56a(Fig. 8) be positioned at the position of the side's of clamping line 14 in the width direction together with stepped wall 31a, the 51a of pedestal 31,51.That is, square line 14 leaves stepped wall 31a, the 51a of pedestal 31,51, by stepped wall 36a, the 56a of the pressing component 36,56 declined, the squeezed bad state of affairs of the party's line 14 can be avoided to occur.
Utilizing after the first and second grasping device 30,50 separates the interval side of the holding line 14 of regulation, processing servomotor 72 by processing actuator 70 carrys out rotating drive processing ball-screw 73, makes contact component 76 move along Y direction towards square line 14 together with processing driven member 74.And, contact component 76, specifically arc sections 76a are contacted by the square line 14 that the first and second grasping device 30,50 holds from side with both sides.And, after contacting from side with square line 14, make this contact component 76 move along Y direction further, as shown in Figure 7 and Figure 8, the part that the contact component 76 of the side's of making line 14 contacts to the side of square line 14 that is Y direction outstanding.Like this, a part of broad ways of the side's of making line 14 is given prominence to lapel shape and is formed from the outstanding fin 12b of the lateral margin of main part 12a.
Now, the arc sections 76a of the contact component 76 that the side's of making line 14 is outstanding to side contacts with the party's line 14, because the party's line 14 is processed to lapel shape along this arc sections 76a, therefore, it is possible to obtain the fin 12b of the shape of the expection along this arc sections 76a.
In addition, although square line 14 from by first and second grasping device 30,50 hold part by bending, but as shown in Figure 8, due to facing the stepped wall 36a of pressing component 36,56, the end of the contact component 76 of 56a is formed with R portion 36b, 56b respectively, thus the party's line 14 along this R portion 36b, 56b by bending.Therefore, it is possible to avoid applying excessive pressure to this bending part.
In addition, because contact component 76 possesses flange part 76b, 76c from the thickness direction side of clamping line 14, the square line 14 that therefore even such as thickness direction is less than Width, because flange part 76b, 76c clamp the thickness direction of the party's line 14, therefore, when the party's line 14 is outstanding to side, can prevent the party's line 14 from deforming in a thickness direction.
Wherein, when the square line 14 making to be held by the first and second grasping devices 30,50 is outstanding to side, make this first and second grasping device 30,50 close to each other along square line 14.The movement of this first and second grasping device 30,50 utilizes the first and second holding movement actuator 40,60 to carry out.Specifically, utilize respective servomotor 42,62 to carry out rotating drive ball-screw 43,63, make the first and second grasping devices 30,50 move along X-direction together with the first and second driven members 44,64.
The mode that the movement of this first and second grasping device 30,50 changes with the length of the square line 14 not making formation above-mentioned fin 12b is carried out.Therefore make the first and second grasping devices 30,50 mutually with the close contact component 76 be positioned in the middle of it of identical speed, form the fin 12b of lapel shape thus.Like this, do not changed before and after the formation of fin 12b by the length of the square line 14 making formation fin 12b, thus the party's line 14 action outstanding to side can be made to become easy, and the state of affairs that when avoiding the side's of making line 14 outstanding to side, the party's line 14 extends occurs.Therefore, it is possible to avoid forming, the square line 14 of busbar 12 extends in fin 12b and the sectional area of the side's of making line 14 reduces, state of affairs generation that its electrical characteristics are changed.
Although hold making the party's line 14 air spider device 22 that outstanding time side line 14 is transferred device 21 to side, but move because this conveying device 21 itself is arranged at the first holding the first driven member 44 using actuator 40, thus this conveying device 21 moves together with the first grasping device 30.Therefore the interval of the first grasping device 30 and conveying device 21 does not change, and the interval can eliminated because of the first grasping device 30 and conveying device 21 changes and the undesirable condition produced.
Like this, after formation fin 12b, the holding of first and second grasping device 30,50 the other side's lines 14 is removed.This makes cramping parts 37 side of leaving line 14 by above-mentioned Width cylinder 33,53, meanwhile makes respective pressing component 36,56 increase from square line 14 by respective thickness direction cylinder 32,52.Remove the holding of the other side's line 14 thus.And turn back to the interval of regulation by expanding between the first and second grasping devices 30,50 by the first and second holding movement actuators 40,60.Meanwhile by processing with the processing servomotor 72 of actuator 70 by processing ball-screw 73 rotating drive round about, make this contact component 76 move to the direction of the side's of leaving line 14 together with processing driven member 74, and turn back to initial state.Terminate the fin forming process forming fin 12b thus.
Alternately repeat such derivation operation and fin formation process, obtain the busbar 12 such as shown in Fig. 9, this busbar 12 forms the fin 12b of the connection of the shape of expection from the lateral margin of main part 12a with the interval of expection with the quantity of expection.Busbar 12 in Fig. 9 illustrates and is formed: the four fin 12b sentencing the chevron be spaced apart of regulation, a place turn back and formed U-shaped fin 12b and at both ends with cantilever-shaped outstanding fin 12c.Wherein, for chevron fin 12b and turn back and form the fin 12b of U-shaped, by making the interval of regulation, the amount of movement of contact component 76 of the square line 14 held by the first and second grasping devices 30,50 change, can separately complete thus.In addition, for the fin 12c at both ends, although not shown, but utilize the first or second grasping device 30 or 50 to carry out the side's of holding line 14, and make contact component 76 and the ends contact from the outstanding square line 14 of this first or second grasping device 30 or 50, and then to the side of square line 14 that is Y direction outstanding.The end of bending side's line 14 thus, thus the both ends being formed in main part 12a are with cantilever-shaped outstanding fin 12c.In addition, the busbar 12 in Fig. 9 is only an example, but is not limited thereto.
Therefore, in the manufacturing installation and manufacture method thereof of busbar of the present invention, busbar 12 is obtained by carrying out bending machining to the square line 14 be extruded in advance, this busbar 12 is formed with the main part 12a that slenderly extends and from the assigned position of this main part 12a to the fin 12b outstanding with the direction that this main part 12a reports to the leadship after accomplishing a task, therefore, it is possible to saving in the past such is the operation of tabular by the square line crimp after bending machining, the manufacturing process of busbar 12 can be simplified than ever.In addition, owing to not needing the in the past required metal die for crimp, therefore, it is possible to reduce the burden of metal die management and obtain more cheap busbar.
