    摘要: A method of manufacturing pipe body by which pipe body with precise quality and closely contacted seam can be made stably by pressing process, and pipe body manufactured by the method are provided. To manufacture a pipe body 1 made of metal with circular or polygonal cross section comprising a seam 5e and a wall 2 or plurality of walls 2, 3 and 4, a pipe-like intermediate product 14 is made by bending a metal plate 6 of which edges to be seam 5e have not yet contacted together. In case for prism pipe, the intermediate product comprises walls 5a, 5b to be contacted and be a wall including seam, and other walls, and both angles of both ends of one specified wall 15 of the intermediate product are larger than those of completed pipe. External forces are applied to adjoining walls 16, 16 of the one specified wall 15 so as for the one specified wall 15 to include convex portion 32 to outer side and for the seam 5e to be closely contacted together, then another external force is applied to the one specified wall 15 so as to be flat and to be the completed pipe 1. A spring back force tending the one specified wall to be back as original convex form is induced and it maintains the seam 5e in dose contacted condition. In case for cylindrical pipe, the intermediate product has an oval cross section with its seam contacted together, and an external force is applied in long axis direction of the oval so as for the oval to be circular and to be a completed pipe 1. A spring back force tends the pipe to be back as original oval form is induced and it maintains the seam 5e in close contacted condition.

    摘要: The present invention provides a pipe body of which the edge sections contact with each other stably and which can be formed only by means of only a press processing without performing a welding in mass-producing, wherein separation-prevented engagement due to deformation of at least one of the engagement sections absorbs the spring back in the press processing. Also, the present invention provides a pipe body, a metal plate for the pipe body and a forming method of the pipe body using the sheet metal for the pipe body. The pipe body includes a pair of edge sections 1e, 1f forming closed end surface by means of contact with each other, wherein surroundings of each edge sections 1e, 1f form a plane 1a jointly when each edge sections 1e, 1f are in contact with each other, and at the same time, engagement sections consisting of female engagement section 1g and male engagement section 1h engaged with each other are formed in the edge sections 1e, 1f and the edge sections 1e, 1f get in contact with each other closely by means of separation-prevented engagement due to deformation of at least one of the female and male engagement sections 1g, 1h.
