Therefore, a case will be described as an example in which the chain-shaped bus bar 35 is cut from a predetermined position to manufacture crank-shaped split bus bars 1A and 1B (hatched portions in FIG. 1) that form the bus bar 1.

First, a chain-shaped bus bar 35 patterned from two horizontal members 39A and 39B and a large number of vertical members 41 orthogonal to the horizontal members 39A and 39B in a checkerboard pattern is used as a base material. The predetermined position of 35 is cut line 43
Cut along A to 43G to obtain the desired split bus bar 1
A and 1B are manufactured.

As shown in FIG. 3, the cutter 45 for cutting the chained bus bar 35 includes a first vertical blade 47A and a second vertical blade 47B for cutting the lateral members 39A, 39B.
A first horizontal blade 49A, a second horizontal blade 49B, a third horizontal blade 49C, and a fourth horizontal blade 49D for cutting the vertical member 41 are provided at the upper and lower positions of the horizontal members 39A and 39B. The cutter 45 is relatively moved in the horizontal direction (the direction of the arrow in the drawing) to position it at the desired cutting lines 43A to 43G, and the vertical blade 4
Among the 7A to 47B and the horizontal blades 49A to 49D, only the corresponding blade is pressed by a striker (not shown) to perform cutting.

For example, when manufacturing the divided bus bar 1A shown in FIG. 1, the following steps (1) to (2) are performed. The horizontal members 39A and 39B are cut along the cutting lines 43A and 43B using the first vertical blade 47A and the second vertical blade 47B. Next, the cutter 45 is moved to move the second vertical blade 47B.
The cutting line 43C of the lateral member 39B is cut by using only. Next, the cutter 45 is moved to move the second vertical blade 47B.
The cutting line 43D of the lateral member 39B is cut by using only. Next, the cutter 45 is moved to move the second horizontal blade 49B.
And the cutting line 43 of the vertical member 41 using the third horizontal blade 49C.
Cut off E and 43F. Finally, the cutter 45 is moved to move the first vertical blade 47
A is used to cut the cutting line 43G of the lateral member 39A.

As described above, according to the method for manufacturing a bus bar of this embodiment, it is desirable that the chain-like bus bar 35 is patterned from the horizontal members 39A and 39B and the vertical member 41 in a cross pattern and is commonly used as a base material. Position lateral members 39A, 39
By cutting B or the vertical member 41, the divided bus bars 1A and 1B having a desired shape can be manufactured.
The cost of the bus bar 1 can be reduced. Also,
Since the vertical member 41 and the horizontal members 39A, 39B are simply cut by the cutter 45 corresponding to the chain bus bar 35, the divided bus bars 1A, 1B can be easily manufactured by a simple device.

In the above embodiment, the case where the two lateral members 39A and 39B are provided has been described.
The same can be applied to the case having three or more lateral members 39. Further, the cutter 45 has been described as having a plurality of vertical blades 47 and a plurality of horizontal blades 49, but a cutter having only one vertical blade 47 and one horizontal blade 49 may be used. However, in this case, the cutter needs to perform relative movement and positioning in the vertical and horizontal directions.

[0021]

As described above, according to the method of manufacturing a bus bar of the present invention, the bus bar having a desired shape is manufactured by cutting predetermined positions of the horizontal member and the vertical member with a cutter, so that the cost of the bus bar is reduced. be able to.

Further, the cutter is provided corresponding to the arrangement of the vertical member and the horizontal member, and is provided with a horizontal blade for cutting the vertical member and a vertical blade for cutting the horizontal member. Is used to cut the chained bus bar into a desired shape. Therefore, when cutting the horizontal member and the vertical member of the chain-like bus bar as the base material, the horizontal member is cut by the vertical blade, and the vertical member is cut by the horizontal blade to manufacture a divided bus bar of a desired shape. Therefore, the bus bar can be easily manufactured. Therefore, the cost of the bus bar can be further reduced.
