った。2. Description of the Related Art As a conventional processing line for a long object such as an H-section steel, a cutting process for cutting into a predetermined length after completion of a drilling process for forming a large number of through holes through which sewer pipes and bolts are inserted. It is usually done in order. As the speed of the processing line is increased, drilling work is being improved, and a drilling machine capable of high-speed processing is being developed. On the other hand, the processing speed is not so much improved as a post-cutting process, and the balance of the processing speed of this drilling-cutting processing line is broken,
When transporting to the cutting device side, the H-section steel that has been subjected to the drilling process is transported by a roller conveyor or the like, and the workpiece (H-section steel) after the drilling process is temporarily stored in standby. For example, as shown in FIG.
Numerical control units (NC) are connected to the drilling device 2 and the drilling device 53, respectively, and the H-section steel, which is a workpiece, is conveyed from the right side. Is perforated. After processing, the conveyor 54
Is conveyed to the cutting device 51. However, since the cutting operation takes time, the slide conveyor 5 provided in the middle is required.
5 or trays 55a, 55b, etc. The stored and drilled H-section steel is carried into the cutting device 51 and cut into a predetermined length, and the cut H-section steel is discharged by the slide conveyor 56. As described above, in the past, it was often stored temporarily in the storage storage unit.

の無端帯鋸状のベルトによる切断も行われていた。In this cutting apparatus, cutting is started by gradually approaching a cutting blade (round saw blade) called a cold saw from the side surface of the H-shaped steel, and the cutting is completed when the other side surface is cut. The cutting step was completed by retracting the rotary cutting blade from the H-shaped steel. In addition, cutting has also been performed using a seesaw-shaped endless band saw-shaped belt as a cutting blade.

ため、バンド・ソーでは限界である。However, such H
In the case of the band saw used in the cutting process in a section steel processing line, the width of the H section steel is usually about 1000 mm, and the H section steel is a thin blade having a thickness of about 1 to 2 mm. However, it was difficult to guide the cutting blade to the span for this cutting due to the structure of the cutting device, and the cutting speed (processing speed) could not be increased. Furthermore, in recent years, the width of the H-section steel is 1500 mm, which is often used.

なっている。[0005] As described above, since the conventional band saw has a long cutting time, two or more cutting machines are required for one drilling machine in terms of a processing line. Therefore, a space for the factory is also required correspondingly, and peripheral equipment for distributing to a plurality of band saw blades, such as a conveyor and a traverse, are required.

ている。In this case, the saw blade cannot be thickened due to the band / saw mounting structure, so the strength of the saw blade is not sufficient, so that the saw blade flows during the cutting operation and the squareness of the cut surface cannot be obtained. In addition, this saw blade is irreproducible and is not economical because it is disposable. Furthermore, the saw blade feed direction (cutting direction)
Is in one direction (up and down), so the cutting length of the H-shaped steel varies greatly depending on the cutting position. In such an intermittent cutting, vibration is large and greatly affects the life of the blade.

った。When a cold saw, which is a rotary blade, is used instead of the band saw, there is only one saw blade.
To cut a 00 mm H-section steel, a rotary blade having a diameter of 1400 mm or more was required. Since such a large rotary blade is heavy, mounting work, removal work and polishing work for regeneration are heavy labor, and it takes time, so that the processing time cannot be shortened as a whole. Furthermore, although the cutting speed is higher than the band saw blade, it is slower than the processing speed of the drilling machine, and the processing balance cannot be maintained one-to-one, requiring a sorting machine. As a whole, the processing line could not be speeded up.

An object of the present invention is to provide an H-section steel cutting device capable of increasing the processing speed of cutting and processing a large number of H-section steels in a short time.

を向上改善することができる。The above object of the present invention is attained by the following constitution. After punching at a predetermined location, the H-shaped steel is conveyed to the cutting section side by a conveying device, and the cutting blade is approached from the side of the flat plate of the H-shaped steel fixed at the cutting position, and the H-shaped steel is cut to a predetermined length by the cutting blade. In the H-section steel cutting apparatus for cutting, the two cutting blades arranged opposite to the two flat surfaces of the H-section steel fixed at the cutting position are brought close to both side faces of the H-section steel, and cut from both sides. One step, a second step of interrupting the cutting operation from both sides by the cutting blade leaving an uncut part in a part, and retreating both side cutting blades to an initial position, and one or both of the cutting blades The cutting blade is moved perpendicularly to the moving direction of the first step and stopped at a predetermined position, and the cutting blade is moved in parallel with the cutting direction of the first step, or the cutting blade is lowered after being moved in parallel, and the cutting blade is lowered. Cut in the direction to cut the uncut part left in one process And a fourth step in which after completely cutting the H-section steel, the cutting blade, which has contributed to the cutting in the previous step, is moved to the initial position while moving in the reverse direction to the third step. And a process. As a specific mechanism used in such a configuration, a fixing member holding each support member that supports each cutting blade arranged opposite to the two flat surfaces of the H-section steel is opposed to each other along the guide member, It has a configuration in which a driving source for moving in opposite directions and one or both support members are slidably held up and down.
Further, the cutting speed can be improved and improved by the fact that the cutting blade is a rotary blade.

加工することができる。According to the H-section steel cutting apparatus of the present invention, two cutting blades rotatably provided on each support member in the first step are mounted on the H-shaped steel cutting apparatus.
The cutting speed is reduced because the H-section steel is cut by moving forward on a straight line in opposition from both sides of the flat face of the section steel, and, moreover,
In the third step, the central uncut portion can be cut by one cutting blade, so that even a large H-section steel can be reliably cut in a short time without being affected by the diameter of the cutting blade. In addition, since the round saw blade is used, the cutting time is short, and the processing balance between the drilling operation and the cutting operation, which has been difficult in the conventional processing line, is maintained, and the processing can be performed in a one-to-one relationship.
