[Prior Art] A step-by-step forming process in which a rod-shaped tool abuts against the surface of a metal plate material and which is sequentially formed along the contour line in accordance with the shape of the shaped article is disclosed in Patent Document 1 below. . [Patent Document 1] Japanese Laid-Open Patent Publication No. 2002-144 (European Patent Publication No. 1147832A2). [Disclosure] [Problem to be Solved by the Invention] Fig. 1 is a perspective view of a product produced by sequential molding processing by applying the present invention. In the whole product, the second molding portion 20 having a three-dimensional shape is protruded from the center portion of the first molding portion 10 having a cross-sectional shape bent in a two-dimensional shape. Fig. 5 through Fig. 9 show a process for producing the article 1 by a usual sequential forming process. The jig 100 for forming on the stage 50 is a first model member 1 1 0 having a first molded portion 1 对应 corresponding to the product, and a second model member corresponding to the second molded portion 20 of the product. 1 2 0. -5- 1288671 (2) The metal plate 1 4 0 as the work material (material) is in the plane, and its periphery is supported by the work object 1 3 0 and the work object] 5 0 work object support 1 3 0 is The tool 110 can be lowered from the top of the second model member so that the axis can be moved in the vertical direction of the water in the vertical direction. Figure 6 is a summary of the sequential forming process, the path of Figure 7. As shown in Fig. 6 and Fig. 7, the workpiece is formed into a product shape by forming the entire workpiece by the path Ρ 2 in which the first molding portion diameter Ρ 1 and the second molding portion are formed. As shown in Fig. 8, the sequential forming processing tool 160 is formed by moving the upper surface of the workpiece 1 40 on the parallel X-axis and advancing only at a pitch Ζ in the z-axis direction. In the eighth, although the processing tool 160 is successively formed, it is actually supported. The y which moves along the contour line is displayed by the three tools 160. That is, once the pitch P of the advancement is made constant, the contour line is formed. When the interval between the paths in which the curvature radius of the curved surface of the first molded portion is changed is widened, the formability is deteriorated. Therefore, the advancement pitch is reduced and the formability is improved, and the entire length of the forming path is increased, and the processing time is increased. Bad longevity. (9) (a) is a state in which the first forming unit 1 〇 and the second forming unit 20 are processed in the state in which the sequential forming process is completed, and the material shape is controlled in accordance with the outer peripheral shape of the product. . . The successive flattening directions and the roads that are not formed are applied in a plane-by-plane shape, and each figure on the side of the graph is a 1st story. Further, along the time of the big time, the neighboring cockroach will produce the crop 1 400 〇 140 -6 - 1288671 (3) The appropriate trimming (t r i m m i n g ) is processed C 1 to obtain the product i. In the work material 140, the end material having the space 1 42 which is cut by the trimming process is left, which is a cause of deterioration of the yield of the material. The present invention provides a sequential forming process which can solve the above problems. Method and device. [Means for Solving the Problem] In order to achieve the above object, the third-order shape successive molding method of the present invention prepares a workpiece having a curved surface corresponding to the first molding portion, and a part of the workpiece is subjected to sequential forming processing. The second forming portion of the three-dimensional shape is processed. Then, the sequential forming processing apparatus is provided with a platform for holding the workpiece around the workpiece and a platform for carrying the workpiece, and a sequential forming tool equipped for the vertical direction of the platform, and is provided corresponding to the curved surface of the workpiece. There are work support and work folder. [Embodiment] Figs. 2 to 4 are explanatory views showing a method of producing a product by sequential forming processing of the present invention. In the present invention, the forming jig 200 disposed on the stage 50 is a model member 220 provided only with the second forming portion corresponding to the product. The metal plate 240 as a work material (material) is processed in advance on the curved surface having the first molded portion and the same dimensional surface of the product. -7- 1288671 (4) The workpiece holder 203 is a pedestal surface 232 having a surface conforming to the workpiece 240. Similarly, the workpiece holder 250 has a gripping surface 253 that coincides with the curved surface of the workpiece 240. At the time of processing, the sequential forming processing tool 260 and the platform 50 move relative to each other along the plane shape of the second forming portion on the X-Y plane, and the sequential forming processing tool 2 60 is toward the Y axis. The relative movement of the direction is controlled such that the successive forming tool 250 is moved along the first forming portion, that is, along the curved surface of the workpiece 240. Further, as the processing progresses, only the sequential forming processing tool 2 60 is moved at a predetermined pitch P 2 , and the second forming portion is processed in the same manner as the normal sequential forming process. As shown in Fig. 4, the workpiece 240 is given a second-order curved surface in advance. Since the second molding portion of the third dimension is formed only by successive molding, the molding path is shortened, and the processing time is also shortened.
