形成するのが通常である。Conventionally, when manufacturing a metal member of this kind, a roll forming machine is used, and a single metal strip material is continuously bent and formed by the roll forming machine to form the main body of the metal member, It is usual that the locking portion is also formed by folding back from the main body portion of the metal member or projecting as a ridge on the inside of the channel portion.

事態を招くことになる。DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, according to this method for manufacturing a metal member, the metal member is folded back with the same metal strip material as that of the main body portion of the metal member, although the locking portion of the other member is not required to have so much strength. Since they are formed as parts or ridges, a relatively large number of forming rolls are required only for forming these. In particular, there are many bending points, and when the angle of bending and folding is large, many forming rolls must be assembled accordingly. In addition to this, when turning back to an extremely small radius, small cracks are generated in the turning back part, and the metal strip material slides in contact with many forming rolls at the part where the turning up part and the ridges are formed and partially cuts. As a result, it becomes a minute metal piece, which may cause an indentation on the outer surface due to the fact that the metal piece adheres to the plate surface and comes into sliding contact with the forming roll.

Weld and join at a pitch of. At this time, if the main metal strip material M is held in a flat plate shape, the sub metal strip material S can be easily joined, which is preferable. Alternatively, the main metal strip material M may be partially flat, and the sub metal strip material S may be in contact with each other and partially rolled by a welding machine from above and below or from the left and right. Spot welding spots on the drawing x
Immediately after the welding process, as shown in FIG. 2, two auxiliary metal strips S, which are locking portions for attaching the glass run channels, are joined to different positions on the surface of the main metal strip M immediately after the welding process. . This sub metal strip material S
After joining, the main metal strip material M is sent to a cold roll forming machine 13 consisting of a group of rotationally driven rollers and is bent and formed as a main body of a metal member having a predetermined irregular cross-sectional shape. The main body has an inner surface m 1 and an outer surface m 1 as shown in FIG.
2 , a substantially groove-shaped channel portion having a bottom surface m 3 and a reinforcing portion m 4 that is curved and formed outward from the inner side surface m 1 , and the bottom surface m 3 and the back surface of the reinforcing portion m 4 are formed after this bending molding. The rotary spot welder 14 is configured to weld and join at a predetermined pitch. In this state, the sub metal strip material S is located at the end of the channel portion, and when it is formed as an extremely small locking portion without bending, it is immediately cut to a predetermined size by slicing to a predetermined size, so that the vehicle door frame It can be used as a material. On the other hand, when the sub metal strip material S is bent into a predetermined shape, it can be easily bent because the sub metal strip material S is formed of a thin plate. It is advisable to form a groove V as shown in FIG. 4 at a desired bending position along the line. This sub metal strip material S can be bent and formed by a forming roller 16 as shown in FIG. 5 so as to stand up from the plate surface of the main metal strip plate M, and the forming roller 16 does not have to be rotationally driven. The material S can be bent. Finally, the shaper may be finely shaped by passing it through a shaping device 17, for example, a die having an insertion hole of substantially the same cross section as the product outer shape, and cut into a predetermined size with a cutting machine 18.
