Utilizing after the first and second grasping device 30,50 separates the side of controlling, the interval line 14 of regulation, come rotating drive processing with ball-screw 73 by the processing of processing with actuator 70 with servomotor 72, with driven member 74 contact component 76 is moved with processing towards square line 14 along Y direction.And, make contact component 76, specifically the arc sections 76a square line 14 of being controlled by the first and second grasping device 30,50 from side and both sides contacts.And, moving along Y direction with further making this contact component 76 after square line 14 contacts from the side, as shown in Figure 7 and Figure 8, the part of contact component 76 contacts of the side's of making line 14 is outstanding to side that is the Y direction of square line 14.Like this, a part of broad ways of the side's of making line 14 fin 12b that formation is given prominence to from the lateral margin of main part 12a so that the shape that turns back is outstanding.
At this moment, the arc sections 76a of the contact component 76 that the side's of making line 14 is outstanding to the side contacts with the party's line 14, owing to the party's line 14 is processed to the shape that turns back along this arc sections 76a, so can access along the fin 12b of the shape of the expection of this arc sections 76a.
In addition, although square line 14 from by the first and second grasping device 30,50 parts of controlling by bending, but as shown in Figure 8, because the end at the contact component 76 that faces pressing component 36,56 stepped wall 36a, 56a is formed with respectively the 36b of R section, 56b, thus the party's line 14 along the 36b of this R section, 56b by bending.Therefore can avoid this bending part is applied excessive pressure.
In addition, because contact component 76 possesses from flange part 76b, the 76c of thickness direction clamping side line 14, even the therefore thickness direction square line 14 less than Width for example, because the thickness direction of flange part 76b, 76c clamping the party line 14, therefore when the party's line 14 is given prominence to the side, can prevent that the party's line 14 from deforming at thickness direction.
Wherein, when making the square line 14 of being controlled by the first and second grasping devices 30,50 outstanding to the side, make this first and second grasping device 30,50 close to each other along square line 14.This first and second grasping device 30,50 movement utilize first and second to control and mobilely carry out with actuator 40,60.Particularly, utilize servomotor 42,62 separately to come rotating drive ball- screw 43,63, with the first and second driven members 44,64 the first and second grasping devices 30,50 are moved along X-direction.
This first and second grasping device 30,50 movement are carried out in the mode that the length that does not make the square line 14 that forms above-mentioned fin 12b changes.The first and second grasping devices 30,50 are approached with identical speed mutually be positioned at its middle contact component 76, form thus the fin 12b of the shape that turns back.Like this, do not change before and after the formation of fin 12b by the length that makes the square line 14 that forms fin 12b, thereby the party's line 14 action outstanding to the side become easily, and the state of affairs generation that the party's line 14 extends when avoiding the side's of making line 14 outstanding to the side.Therefore the square line 14 that can avoid consisting of busbar 12 extends in fin 12b and state of affairs generation that the sectional area of the side's of making line 14 reduces, makes its electrical characteristics to change.
Although control making the party's line 14 air spider device 22 that outstanding time side line 14 is transferred device 21 to the side, but control mobile the first driven member 44 with actuator 40 because this conveying device 21 itself is arranged at first, thereby this conveying device 21 is mobile with the first grasping device 30.Therefore the first grasping device 30 does not change with the interval of conveying device 21, and can eliminate the undesirable condition that the interval because of the first grasping device 30 and conveying device 21 changes and produces.
Like this, after forming fin 12b, remove controlling of the first and second grasping devices 30,50 the other side's lines 14.This is by above-mentioned Width cylinder 33,53 and make cramping parts 37 side's of leaving lines 14, meanwhile by separately thickness direction cylinder 32,52 and pressing component 36,56 is separately risen from square line 14.Remove thus controlling of the other side's line 14.And by first and second control mobile with actuator 40,60 will be between the first and second grasping devices 30,50 expansion and turn back to the interval of regulation.Meanwhile will process with servomotor 72 with the processing of actuator 70 by processing and use round about rotating drive of ball-screw 73, and with driven member 74 this contact component 76 be moved with processing to the direction of the side's of leaving line 14, and turn back to initial state.Finish to form thus the fin forming process of fin 12b.
Alternately repeat such derivation operation and fin and form operation, obtain busbar for example shown in Figure 9 12, this busbar 12 from the lateral margin of main part 12a with the interval of expection and form the fin 12b of connection usefulness of the shape of expection with the quantity of expection.Busbar 12 among Fig. 9 illustrates and is formed with: turn back with fin 12b, a place of the chevron that is spaced apart of regulation everywhere and form the fin 12b of U word shape and at both ends with cantilever-shaped outstanding fin 12c.Wherein, for the fin 12b of chevron with turn back and form the fin 12b of U word shape, the interval of the regulation by making the square line 14 of being controlled by the first and second grasping devices 30,50, the amount of movement of contact component 76 change, and can separately finish thus.In addition, for the fin 12c at both ends, though not shown, utilize the first or second grasping device 30 or 50 side's of controlling lines 14, and contact component 76 contact with end from this first or second grasping device 30 or 50 outstanding square lines 14, and then give prominence to side that is the Y direction of square line 14.The end of bending side's line 14 thus, thus the both ends that are formed on main part 12a are with cantilever-shaped outstanding fin 12c.In addition, the busbar 12 among Fig. 9 only is an example, but is not limited to this.
Therefore, in the manufacturing installation and manufacture method thereof of busbar of the present invention, by being carried out bending machining, the square line 14 that is extruded in advance obtains busbar 12, this busbar 12 is formed with slenderly the main part 12a that extends and from the assigned position of this main part 12a to the outstanding fin 12b of the direction of reporting to the leadship after accomplishing a task with this main part 12a, therefore can save was tabular operation with the square line crimp after the bending machining in the past like that, can be more in the past than the manufacturing process of simplifying busbar 12.In addition, owing to not needing the in the past required metal die that is used for crimp, therefore can reduce the burden of metal die management and obtain more cheap busbar.
