BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for bending flat electric wires, and more particularly to a method for bending flat electric wires to form bent portions required for wiring and wiring.

0002

2. Description of the Related Art Conventionally, this type of flat electric wire has been bent by a method outlined in FIGS. 7, 8, and 9.

That is, a backing plate 2 is placed along the bending position of the flat electric wire 1 to be bent (FIG. 7).

Next, the flat electric wire 1 is bent at the position of one end 3 of the backing plate 2 so that the backing plate 2 is sandwiched therebetween (FIG. 8).
).

[0005] After that, the flat electric wire 2 with the backing plate 2 bent
The bent portion 4 is formed on the flat electric wire 1 by pulling it out from between the wires (FIG. 9).

[0006]

In the conventional method, there is a problem in that the folds at the bent portion of the flat electric wire are loose, and the bent portion 4 of the flat electric wire 1 opens as shown in FIG.

For this reason, as shown in FIG. 11, after the bending process is performed, as a separate step, the fixed part of the bent part 4 where the flat electric wire 1 overlaps is wound with, for example, adhesive tape 5. It is necessary to fix the fold.

Alternatively, as shown in FIG. 12, the pressing plates 6 and 7 of the presser 8 are brought into contact with both overlapping surfaces of the flat electric wire 1, and the bent portions of the flat electric wire are pressed by the pressing plates 6 and 7. ing.

[0009] Therefore, in the conventional bending method,
When bending a flat electric wire, it is necessary to fix or press the bent part each time as necessary. In addition, the bending position is not stable at the desired constant position, and due to the rigidity of the wire, the folds at the bending part may not always be completely bent and may not open properly. There's a problem.

An object of the present invention is to solve the above-mentioned problems, so that the bending position of the flat electric wire is stabilized at a desired fixed position, the fold of the bending part is completely bent after the bending process, and
It is an object of the present invention to provide a method for folding a flat electric wire, which performs a reliable and stable bending process that does not open regardless of the rigidity of the electric wire, using a series of processing methods.

[0011]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a method for bending flat electric wires when bending flat electric wires, in which the wires are arranged facing each other with a gap at a predetermined interval. A flat electric wire is placed perpendicularly to the sandwich plate along one opposing edge of the sandwich plate, and a flat electric wire is placed on the portion of the flat electric wire located above the gap between the opposing edges of the sandwich plate. The edge portions of the folding plates are brought into contact with each other, and the flat electric wire is press-fitted by a predetermined length into the opposing gap between the sandwiching plates and bent, and then the folding plate is inserted from the press-fitted and bent flat electric wire. It is characterized in that the bent portion of the flat electric wire is pressurized by the opposing sandwich plates while being pulled out, and the bending process is performed in a series of steps.

0012

[Operation] The present invention makes the bending position constant by press-fitting a desired bending portion of a flat electric wire between two opposing sandwiching plates to a desired length using a folding plate and bending the wire. By continuing to press the wire with a sandwich plate, sufficient bending can be performed in a short time and in a series of steps regardless of the rigidity of the wire.

Embodiments will be described below based on the drawings.

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a diagram showing the main parts of a structure for carrying out the folding method of the present invention.

FIGS. 2 to 6 schematically show the folding process of the present invention.

The method for bending a flat electric wire according to the present invention will be explained below with reference to FIGS. 1 and 2 to 6.

Reference numerals 14 and 15 indicate sandwiching plates which are arranged with a predetermined gap between them, and are driven by the pressing section 12 in a direction in which their opposing surfaces approach and press against each other.

Reference numeral 13 denotes a folding plate, in which a flat electric wire 16 is folded and press-fitted vertically downward into the opposing gap between the sandwiching plates 14 and 15 by the folding portion 11, and when the press-fitting is completed, the flat electric wire 16 is pulled vertically upward. driven by.

Driving the pressure unit 12 that applies pressure to the sandwich plates 14 and 15 and setting the pressure force, driving the folding plate 13 up and down in the vertical direction, and bending the flat electric wire between the sandwich plates 14 and 15 of the folding plate 13. The control unit 1 controls the setting of the press-fit length.
Performed by 0.

Sandwich plates 14 set at predetermined intervals,
A flat electric wire 16 is placed along one opposing edge of the wire 15 (in this embodiment, the upper opposing edge) (FIG. 2).

[0021] Drive the folding plate 13 vertically downward;
The lower edge of the folding plate 13 is brought into contact with the bent portion of the flat electric wire 16 (FIG. 3).

Further, the folding plate 13 is driven downward, and a predetermined length of the flat electric wire 16 is press-fitted into the opposing gap between the sandwiching plates 14 and 15, and the flat electric wire 16 is bent (FIG. 4).

Next, the flat electric wire 16 is sandwiched between the plates 14 and 15.
The folding plate 13 is folded to a predetermined length into the gap between the facing surfaces of the folding plate 13, and then pulled out while the folding plate 13 is sandwiched therebetween (FIG. 5).

While pulling out the folding plate 13, the sandwiching plates 14 and 15 are bent and pressure is applied from both sides of the bent flat electric wire 16 to press and fix the fold of the bent portion of the flat electric wire 16 ( Figure 6).

After that, the pressure between the sandwich plates 14 and 15 is removed, and the flat electric wire 16 with the fixed crease formed is placed between the sandwich plates 14 and 15.
By extracting from between 15 and 15, a bent portion of a desired length can be stably formed in a short time.

The spacing between the sandwiching plates 14 and 15 facing each other is set to 0.5 to 5.0 mm in the case of a normal flat electric wire, and the thickness of the folding plate 13 is selected to be about 0.2 to 1.5 mm. Three types of electric wires with different rigidity, thickness 3mm, 2mm, 1.
As a result of bending five 5mm flat electric wires with bending lengths of 40mm, 30mm, and 20mm, the bending positions were stably secured, and even 24 hours after the bending process, It was confirmed that there were no samples in which the folds were too wide.

[0027]

As described above, the present invention is capable of press-fitting a flat electric wire to a desired length into the gap between two opposing sandwich plates using a folding plate, bending it, and then pulling out the folding plate and press-fitting the wire. Since the creases of the bent portion of the bent flat electric wire are pressurized and fixed by a sandwich plate, sufficient bending can be performed stably in a short time through a series of processing steps, regardless of the rigidity of the wire. The dimensional accuracy of bending is also improved.
