現れず，商品価値を損なうことはない．DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method of processing a profile. (Prior Art) In addition to H-shaped members and I-shaped members, various shaped members having various cross sections are manufactured and used. These profiles are often formed or deformed by rollers. In such a case, the cross-sectional dimension of the profiled product must be changed by the type of roller, and the margin of change in the product cross-sectional dimension due to the roller adjustment is small. Therefore, many rollers and replacement work are required. It was. In addition, since the web and the flange of the profile manufactured by the conventional method are flat, the profile easily peels off from the cement or the coating material, and the only resistance between the two is the frictional resistance without any snagging. The composite strength between the cement and the coating material and the profile was weak. Furthermore, in the conventional method, the width of the material cannot be changed unless the roller set is replaced, because the material stretches only in the length direction when the shape is deformed. In order to increase the width, it is conceivable to extend the area near the center of the cross section with a roller. In this case, however, only the part to be processed is likely to extend in the length direction, causing ripples, reducing the commercial value, and causing twisting and bending. occured. In the conventional method, irregular buckling occurs at the part where the width is to be reduced, which impairs the commercial value. (Problems to be Solved by the Invention) It is a first object of the present invention to provide a method of processing a profile capable of adjusting the cross-sectional dimension of the profile. A second object of the present invention is to provide a shaped material having excellent adhesion to cement and a coating material. It is a third object of the present invention to provide a method for changing the width without losing the shape of the profile. (Means for Solving the Problems) The present invention is configured as follows. 1) According to the present invention, as shown in FIGS. 1 to 6, a hollow portion is periodically formed at substantially the same position on the front and back sides of a web portion 1 or a flange portion 2 of a shaped material with a pair of rollers 3 interposed therebetween. This is a method of processing a shaped material characterized by raising the periphery of the part from the web surface and deforming this material in the width direction. When the concave portion is periodically deformed at substantially the same position on the front and back sides of the web portion 1 or the flange portion 2 of the profile between the roller pair 3, the material removed by the concave portion 4 flows in the width direction, and a part of the material is removed. As shown in FIG. 6, the raised portion 5 is raised from the web surface or the flange surface 6.
By doing so, the problems of the conventional method described above can be solved. That is, in the example of FIGS. 1 to 4, the cross-sectional dimension of the profiled material is increased by attaching the diaper to the web portion 1 to increase the web width, and in the example of FIG. Is expanded. Due to the presence of such a hole, the adhesiveness to cement and coating material is excellent, and the width can be changed without damaging the shape of the profile, such as waving or bending. 2) In the present invention, the rotating shaft 7 of the roller pair 3 may be parallel like a general roller processing machine. However, in order to increase the width and the bulging portion 5 around the concave portion, FIGS. As shown in FIG. 5, the web portion or the flange portion of the profile is periodically recessed at substantially the same position on the front and back with the rotating shaft 7 interposed between the roller pair 3 inclined in the profile longitudinal direction 8 with respect to the profile cross section. It is desirable to increase the web width or flange width of the profile by forming a part and making the periphery of this depression rise from the web surface or flange surface. Figures 1 to 5
As shown in the figure, when the roller pair 3 is inclined and the roller pair rotates in the direction of the thin arrow, a force acts on the material in the length direction and a force acts on the material in the width direction. When the rollers are tilted in opposite directions, the force for advancing the material in the width direction can be applied to the front and back of the material in opposite directions. When the web or flange is deformed by inclining the rotation shafts of the roller pairs in opposite directions, the material tends to flow in the width direction, and the web or flange width is easily widened. The climax also increases, and a great effect is achieved in achieving the object of the invention. 3) In the present invention, as shown in FIGS. 3 to 5, a greater effect can be obtained by providing a plurality of roller pairs. That is, a tensile force is applied to the material between the pair of rollers 3 in accordance with the inclination of the pair of rollers 3. At this time, a large tensile force can be generated by the engagement between the material and the roller. As shown in FIGS. 3 to 5, when the roller pair 3 is inclined and the roller pair rotates in the direction of the thin arrow, the force from the roller to advance the material in the length direction and the force to advance the material in the width direction. When the roller pair is tilted in the opposite directions as shown in FIGS. 3 and 4, the force for advancing the material in the width direction is applied between the roller pair in the opposite direction and the material therebetween. You can make it act. 4) In the present invention, preferably, as shown in FIG. 1 to FIG. 5, a hollow portion is periodically formed at substantially the same position on the front and back sides of the web portion 1 or the flange portion 2 of the shape member with the roller pair 3 interposed therebetween. The method of processing a profile according to any one of the above items 1) and 3), wherein the periphery of the concave portion is raised from the web surface, and the web width or the flange width is adjusted by a width determining roller pair 9 orthogonal to the roller pair. . That is, the first
As shown in FIG. 4 to FIG. 4, a recess 4 is formed in the web portion 1 or the flange portion 2 to increase the width, and then the width is adjusted by a pair of width determining rollers 9 or as shown in FIG. A recess is formed in the portion or flange, and the width is adjusted almost simultaneously or slightly after the width is widened, and the width is adjusted by the roller pair 3 'or the width determining roller pair having substantially the same posture. (Effects of the Invention) According to the present invention, a method of processing a profile in which the cross-sectional dimension of the profile can be adjusted becomes possible. Also. ADVANTAGE OF THE INVENTION By this invention, it becomes possible to provide the shape material excellent in adhesiveness with a cement or a coating material. Further, the present invention can provide a method of changing the width without losing the shape of the profile. According to the present invention, in addition to the H-shaped member and the I-shaped member, shapes having various cross sections can be manufactured. The present invention makes it possible to change the cross-sectional dimension of a profile product without changing the type of roller, and to change the product cross-section for roller adjustment. Since the profile produced by the method of the present invention has an ozone on the web or flange, the profile is easily adhered or mechanically bonded to the cement or the coating material, the frictional resistance is increased, and the cement or the coating material is bonded. The composite strength with the profile increases. In the present invention, it is possible to change the width without changing the roller set by expanding the material in the width direction at the time of shape deformation processing. According to the present invention, such a problem can be solved by absorbing the waving that tends to occur in the length direction at the portion to be processed and the bias of deformation that causes torsion or bending. In addition, the irregular buckling, which is a problem when the width is reduced, is absorbed by the depressed part in the present invention and does not appear on the overview, and does not impair the commercial value.
