In recent years, as the demand for stainless steel channel materials as building materials, interior decoration materials, etc. has increased, there has been a demand for inexpensive and highly decorative channel materials. Further, the channel material 9 includes a web portion 91 and a flange portion 92, as shown in FIG. The web portion 91 and the flange portion 92 form an inner corner portion 901 and an outer corner portion 902.

That is, as shown in FIG. 7, the channel material 9 is defined to have a substantially U-shape according to the JIS standard (channel material). Therefore, the channel material 9 generally has a curved surface R at the inner corner portion 901. As shown in FIGS. 7 and 8, both inner sides 921 and 922 of the flange portion 92 have a taper T. Therefore, as shown in FIG. 8, when this channel material 9 is used as a rail of a food processing machine operating section, when the roll 4 is placed on the lower inner side 922, the taper T exists and the two do not come into close contact. As a result, the outer peripheral surface of the roll 4 and the lower inner side 92 of the channel material
2, and the roll 4 cannot be placed inside the channel material 9. Moreover,
Sufficient space for placing the roll 4 on the lower inner side 922 cannot be secured. Further, when the channel material 9 is attached and fixed by placing a bolt (not shown) on the lower inner side 922 of the channel material 9, a gap S is similarly generated, causing a problem. The present invention has been made in view of these conventional problems, and it is an object of the present invention to provide a method of manufacturing a channel material in which the internal angle portions are substantially right angles.

種金属の平板がある。[Means for Solving the Problems] The present invention relates to a method for manufacturing a channel material, in which the inner corner portion and the outer corner portion where the flange portion and the web portion constituting the channel material come into contact form a substantially right angle. The method includes an intermediate processing step of processing a flat metal plate into an intermediate material by bending it at the boundary between a flange portion and a web portion, and a roll processing step of processing an internal corner portion of the obtained intermediate material while locally heating it. The method for producing a channel material is characterized in that the angle of the inner corner portion is 85 to 90 degrees, and the length of the inner corner portion is 0.5 to 2 times the thickness of the plate. The internal angle portion is a portion of the channel material where the inner surface of the web portion and the inner surface of the flange portion are in contact with each other, that is, the portion forming an internal angle of the channel material (angle α in FIG. 1). and,
The angle α of the interior angle portion is 85 to 90 degrees. Here,
The reason for setting the angle to 85 to 90 degrees is that if the angle is less than 85 degrees, sufficient space for objects such as rolls (pulleys) and bolts to be placed on the lower inner side cannot be secured. on the other hand,
If the angle exceeds 90 degrees, as shown in the prior art, an inclined gap will be created between the lower inner side of the channel material and the above-mentioned ornament, and the two will not come into close contact with each other (see FIG. 8). Further, the length (M) of the interior corner portion is 0.5 to twice the plate thickness (L) from the center of the interior corner portion (see FIG. 1). This is because if it is less than 0.5 times, a curved surface portion will remain at the center of the inner corner portion, while if it exceeds twice, there will be waste in machining. The plate thickness (L) is the plate thickness near the internal angle of the angle material. The inner surface of the angle member may expand outward beyond the length of this inner corner portion. Further, the outer corner portion of the channel material is a portion where the outer surface of the web portion and the outer surface of the flange portion are in contact with each other, that is, the portion forming the apex angle at both ends of the channel material. The angle (β) of the outer corner portion is preferably 85 to 90 degrees, and the length of the outer corner portion is preferably 0.5 to 2 times the plate thickness. As a result, the outer corner portions can better butt against architectural members, interior decoration materials, etc., and their adhesion can be improved. The method for manufacturing the above channel material is to use a roll having the shape shown in Figure 4 to form an intermediate material by bending a flat metal plate at the boundary between the flange and web parts, and to form an intermediate material by bending the metal flat plate at the boundary between the flange and web parts, and using a roll having the shape shown in Figure 4. Form a molded intermediate material. Then, when rolling the intermediate material, the periphery of the inner corner part is heated to a predetermined temperature by high frequency heating, and the roll processing is performed using the roll shown in FIG. 5, so that the angle of the inner corner part is 85~ It is made of a channel material whose angle is 90 degrees and the length of the outer corner portion is 0.5 to 2 times the thickness of the plate. Further, as the metal flat plate, there is, for example, a long thin flat steel plate, a thick billet, a bloom, or other steel material rolled into a flat plate shape. In addition to the flat steel plates mentioned above, there are flat plates made of various metals such as titanium flat plates.

Therefore, an object such as a roll can be placed on the lower inner side of the channel material to bring them into close contact with each other. Further, unlike conventional channel materials, no gap is created between the above-mentioned ornament and the lower inner side. In addition, sufficient space can be secured on the lower inner side for placing the above-mentioned ornaments.

As shown in Fig. 4, the upper roller has protrusions at two locations.
It consists of a roll 24 and a lower roll 25 having V-shaped grooves at two locations. In the above-mentioned rolling process, the intermediate member 1A is bent at right angles in the direction opposite to the protruding portion thereof, and the intermediate member 2B is continuously formed. Further, the intermediate member 1A is a lower roller.
The V-shaped groove of the lever 25 compresses the outer corner portion of the protruding portion while maintaining the perpendicular state as it is, and both side portions are formed. Further, the curved inner corner portion on the opposite side to the outer corner portion is shaped while maintaining the curved state by the V-shaped protrusion of the upper roll 24. In this way, the W-shaped intermediate material 1B shown in FIG. 4 is formed. Note that this molding is performed by warm working.

。In this way, the channel material 1 shown in FIG. 1 with an angle α of 85 to 90 degrees at the inner corner portion and an angle of 85 to 90 degrees at the outer corner portion can be obtained using the roll processing machine described above. I can do it. Also, the length M of the interior corner part is shown in Figure 1.
As shown in , it was 0.5 to 2 times the plate thickness L. In the present invention, a hot working process is employed to form a substantially right-angled protrusion on one side of a flat metal plate, so that internal stress is less likely to occur in the channel material. In addition, since a right-angled protrusion is formed between both sides,
The outer corner portion tends to have a substantially right-angled shape. As shown in FIG. 1, the channel material 1 obtained as described above has an internal angle of 87 degrees, and a length M of the internal angle is 0.5 to 2 times the plate thickness L. . Further, when this channel material 1 is used as a pulley rail, it has a horizontal and wide lower inner side 121, so that a wide roll 4 can be installed. When attaching the channel material 1 to other attachment members via attachments such as bolts, a wide range of attachments can be installed with good adhesion.
