を溶接するように構成されている。 First, a conventional method will be described by taking as an example the cutting of a steel strip when laser beam welding the steel strip. 1 to 5 show a laser beam welding device, in which a gate-shaped fixing frame 2 is fixed to a base 1, and first upper and lower clamps 3, 4 that hold a leading steel strip 5a. The lower clamp 4 is fixed to the base 1 and the fixed frame 2, and the upper clamp 3 is fixed to the base 1 and the fixed frame 2.
is supported by a cylinder 6 attached to the fixed frame 2. The cylinder 7 moves the movable frame 8, and among the second upper and lower clamps 9 and 10 that hold the trailing steel strip 5b, the lower clamp 1
0 is fixed to the movable frame 8, and the upper clamp 9 is supported by a cylinder 11 provided on the movable frame 8. A rail 12 is disposed on the first upper clamp 3, and a laser emitted from a welding torch 13 movably disposed along the rail 12 is used to separate the leading and trailing steel strips 5a and 5b. The butt portion is configured to be welded.

Blades 18 and 19 are fixed in parallel. Further, the cylinder 2 fixed to the shear frame 14
The upper blade holder 21, which is vertically movably supported by
23 are fixed in parallel. In this way, a set of first guillotine shears 24 is created by the first upper and lower blades 22, 18, and a set of second guillotine shears is created by the second upper and lower blades 23, 19. 25 are integrally constructed.

突合せ部を溶接する。 In cutting and welding the materials to be welded using the above-mentioned apparatus, first, the leading steel strip 5a is cut using the first upper and lower clamps 3 and 4, and the trailing steel strip 5b is cut using the second upper and lower clamps 9 and 10, respectively. Hold. Next, the shear frame 14 is moved to the position shown in FIG. 3, and the upper blade holder 21 is lowered by the cylinder 20. When the upper blade holder 21 is lowered, the rear end of the leading rigid band 5a is connected to the first guillotine shear 24.
As a result, the front ends of the trailing steel strips 5b are simultaneously cut by the second guillotine shear 25. Next, the shear frame 14 is moved back to the position shown in FIG. 2, and the movable frame 8 is moved closer to the fixed frame 2 by the cylinder 7, and the cut ends of the trailing steel strips 5a and 5b are brought into abutment. Then welding torch 13
A laser is emitted from the welding section to weld the abutting portions of the leading and trailing steel strips 5a and 5b.

先、後行鋼帯５ａ，５ｂの一方を切断する場合に

ると非常に大きな切断力を要するという欠点があ
つた。 By the way, in the conventional cutting method as described above, the leading and trailing steel strips 5a and 5b were simultaneously cut using two sets of integral guillotine shears 24 and 25.
Previously, this method required twice as much force as when cutting one of the trailing steel strips 5a and 5b, and had the disadvantage that a very large cutting force was required when the steel strip became thicker.

後行鋼帯５ｂを切断する方法が提案された。 As a cutting method that eliminates this drawback, the method shown in FIG.
As shown in FIG. 7, a set of guillotine shears 24
A method has been proposed in which the leading steel strip 5a is first cut as shown in FIG. 6, and then the trailing steel strip 5b is cut as shown in FIG.

突合せ側が変形するという問題があつた。 However, when using such a method, as shown in FIG. 8, the trailing steel strip 5b is pushed down by the upper blade 22 when cutting the trailing steel strip 5b,
There was a problem in that the abutting side of the trailing steel strip 5b was deformed between the start of cutting and the completion of cutting.

ことを目的とするものである。 This invention was made in view of the above-mentioned circumstances. First, one of the two sets of guillotine shears is cut off to be welded, and then the other guillotine shear is used to cut the other workpiece. The object of the present invention is to provide a method for cutting a material to be welded, which reduces the cutting force and does not cause deformation of the material.
以下、この発明を一実施例について説明する。
この発明においては、従来と同様に一体構成の２

る。 The present invention will be described below with reference to one embodiment.
In this invention, as in the past, two
Using a set of guillotine shears, the leading and trailing steel strips 5a,
If the thickness of the steel strip 5b is below a certain level, a large cutting force is not required, so as shown in FIG. 24 and 25 at the same time.
第９図、第１０図は、先、後行鋼帯５ａ，５ｂ

鋼帯５ａ側へ前進させて両者の切断面を突合せ、
次工程のレーザビームによる溶接を行う。 Figures 9 and 10 show leading and trailing steel bands 5a and 5b.
This shows the cutting method when the thickness of the plate is above a certain level. When the leading and trailing steel strips 5a and 5b are thick plates, first, as shown in FIG. 9, only the rear end portion of the leading steel strip 5a is cut by the first guillotine shear 24. Then, as shown in FIG. 10, only the front end of the trailing steel strip 5b is cut by the second guillotine shear 25. Then, as in the conventional case, the trailing steel strip 5b is advanced toward the leading steel strip 5a side, and the cut surfaces of the two are butted,
The next step is welding using a laser beam.
以上のように、先行鋼帯５ａと後行鋼帯５ｂを
順次に切断することにより、ギロチンシヤーの有
すべき切断力を著しく低減でき、かつ、後行鋼帯
に変形を与えることがない。 As described above, by sequentially cutting the leading steel strip 5a and the trailing steel strip 5b, the cutting force that the guillotine shear should have can be significantly reduced, and the trailing steel strip will not be deformed.

断寸法の精度が悪くなるおそれがある。 In addition, in the above cutting method, if the first guillotine shear 24 cuts the preceding steel strip 5a and then the first upper and lower clamps 3 and 4 hold the preceding steel strip 5a, the preceding steel strip 5a will be cut during cutting. Since the force acting in the direction of the plate surface of the band 5a disappears after cutting,
As shown in FIG. 11, the rear end of the preceding steel plate 5a may protrude outward (width d 1 ) from the cutting line. In this state, when the second guillotine shear 25 cuts the front end of the trailing steel strip 5b, the first guillotine shear 24 also performs a cutting operation when cutting the trailing steel strip 5b.
Leading steel strip 5a by first guillotine shear 24
The end of will be cut by width d 1 . For this reason, there is a risk that the rear end surface of the preceding steel strip 5a may become rough and the accuracy of cutting dimensions may deteriorate.
このような問題を解消するためには、第１２図

が２度切断されないようにすればよい。 In order to solve this problem, as shown in FIG. 12, when cutting the trailing steel strip 5b, it is necessary to
a from the cutting line of the guillotine shear 24 in the direction of the clamps 3 and 4 to a position (width d 2 ) where the cut end of the preceding steel strip 5a does not come into contact with the first guillotine shear 24 even if the cutting operation is performed again; Leading steel strip 5a
All you have to do is to prevent it from being cut twice.

る。 As described above, according to the present invention, one of the two sets of guillotine shears that operate simultaneously first cuts one workpiece, and then the other guillotine shear cuts the other workpiece. Therefore, the cutting force can be reduced without deforming the material to be welded during cutting, and the device can be made smaller and lighter.
