Description of the Related Art Conventionally, in order to form a metal plate into a spherical shape by using a mold, the metal plate to be formed is entirely pressed by upper and lower dies. In the case of small-volume production, a desired curved surface is formed by manual beating. In order to form a metal plate into a spherical shape, unlike a gutter-like shape whose cross section in one direction is formed in a curved shape,
It is necessary to form the cross section in two orthogonal directions so as to be both curved. That is, a metal plate (thin plate) like a gutter
Can be easily formed by a roller (press) device, but cannot be easily formed into a spherical shape by using a roller (press) device.

Is partially pressed. Then, the press working process is performed for each feed, and the metal plate 30 is sequentially pressed by the feed pitch so that the metal plate 30 is pressed by the male mold 10.
When it is discharged from between the female and female 20, a molded article having a curved surface as shown in FIG. 4 is formed. A molded article having a curved surface formed in this manner is used, for example, as a corner member of a building having a curved corner. It is not necessary for the feeding step and the pressing step to correspond one-to-one. For example, an irregular processing method such as feeding several times in small increments and pressing once may be used.

A press die formed by simply cutting a sheet material into a predetermined shape and laminating a large number of them easily leaves traces on the surface of the metal plate, but a press die whose pressing surface is formed smoothly by cutting processing If so, the generation of traces by pressing can be prevented as much as possible. As described above, the present invention has been described variously with reference to preferred embodiments. However, the present invention is not limited to the embodiments, and it is needless to say that many modifications can be made without departing from the spirit of the invention. That is.
