Abstract

PURPOSE:To form the section of a shape steel after shearing according to an original drawing and to check the occurrence of harmful burr by shearing the lateral, side of a shape steel through the lowering of an upper movable cutting edge, and then shearing the longitudinal side of the shape steel through the oscillation following the above motion of the upper movable cutting edge. CONSTITUTION:A shearing tool is divided into a fixed cutting edge 31 to shear the lateral side of a shape steel 27 and a pair of fixed cutting edges 33 to shear its longitudinal side, and the fixed cutting edge is formed so as to freely move forth and back, and can be optionally fixed by a fixed cutting edge regulating device 41. Next before the shape steel 27 passes through a hole part formed of a movable cutting edge and the fixed cutting edge, the fixed cutting edge is moved back to lengthen a distance between the shape steel 27 and the fixed cutting edge, and just before the shape steel is stopped and sheared, advanced and fixed to extremely shorten the distance between the shape steel and the fixed cutting edge into an adhering state. On the other hand, the upper movable cutting edges 11, 11a are formed in a bisected type, and oscillatably attached to an upper movable attaching board 4, and after the upper movable cutting edges 11, 11a are lowered to shear the lateral side of the shape steel 27, the upper movable cutting edges 11,11a are oscillated to shear the,longitudinal side of the shape steel 27.

2. Description of the Related Art In the online cutting of rolled steel,
For simple cross-sections such as plates, bars and wires, it is relatively easy to shear, but for complex cross-sections such as H-section steel, there is no efficient shearing method that can be applied online. .

As a method for cutting a steel material having a complicated cross-sectional shape such as an H-section steel, there is a method using a circular saw, a band saw, or gas cutting, but the method using the band saw or gas cutting has a long cutting time and is highly efficient. Since they do not match, a method using a hot saw or a cold saw is most commonly used for online cutting of rolled steel.

The method using a cold saw is to cut by frictional heat between a saw blade and a steel material. The cutting surface is rough and large burrs are generated, and chips are scattered.
The noise at the time of cutting was very large and there was a problem in the work environment. Further, since a large amount of cooling water is used to extend the life of the blade, there is a problem of rusting on the surface of the steel material.

As a cutting method for solving these problems concerning the cutting of such rolled H-section steel, cutting with a shear is considered, but a single-cut for cutting the currently used light-weight H-section steel, etc. In the case of a shear, due to the mechanism of the fixed blade and the movable blade, a large gap between the blade and the steel material cannot be secured, and therefore it is not suitable for online cutting of rolled H-section steel.

[0007] On the other hand, as a conventional example, the actual development of Sho 55-1657
There is a guillotine-type double-cut shear shown in Japanese Patent No. 23. As shown in FIGS. 12 (A) and 12 (B), this is steel material 5
The vertical lower blade 52a that shears the vertical side 53a of 3 and the horizontal lower blade 52b that shears the horizontal side 53b of the shaped steel are integrally arranged in a concave shape surrounding the steel material. The upper blade 51 having the blade tip 55 and the upper blade inclined portion 54 is lowered to shear the steel material 53. Since the points where the moving blade (upper blade) contacts the steel material are concentrated, the lower blade 52 rubs against each other. The blades have a short life because they have heat, and the gap between the lower blade (fixed blade) and the steel material cannot be made large, so it is not possible to cope with changes in the cross-sectional area and size of the steel material. However, it has not been generally adopted due to problems such as roughened shear surface. For this reason, it is not suitable for online cutting of shaped steel.

As described above, according to the present invention, after the horizontal side of the shaped steel is sheared in the same machine by the double-cut method, the upper movable blade divided into two parts leaves the vertical fixed blade in a substantially adhered state. By shearing the vertical side, it becomes possible to perform shearing much more efficiently than the conventional method, and the cross section of the shaped steel after shearing maintains the original drawing and does not cause harmful burrs and is fixed. By adopting a movable fixed blade system, scratches and the like on the surface of the shaped steel did not occur, and it became possible to apply it to online fixed length cutting of as-rolled products such as rolled H-shaped steel.
