摘要： Disclosed are a forming apparatus and method that are able to form a required sectional profile by a variety of forming methods, such as roll forming, die forming or shoe forming, etc., when forming round tubing, angled tubing or open forming stock, are able to perform the required forming in any of these forming processes without losing the manufacturability of conventional roll forming and imparting minimal additional deformation to the formed stock, and that can manufacture high-quality goods with high dimensional precision. Disclosed is a forming apparatus that is constituted to be able to substantially realize the use of, for instance, a large forming roller by using an endless shoe block train, in which a multiplicity of individual shoe blocks, which have a pass on their rotating curved faces, and which pass is able to continuously move in the circumferential direction on an endless track, are connected to provide the same curvature radius and length as a required arc segment of a virtual large-diameter circle to the surface of the endless track of the forming segments that come in contact with the stock being formed.

摘要： An object of the present invention is to provide a forming method and a forming machine in which in forming e.g., a round steel pipe, predetermined forming can be performed with less additional deformation imparted to a workpiece without deteriorating the productivity of the conventional roll forming, thereby manufacturing a high-quality product with high dimension precision. To achieve this object, the present invention provides a forming method and a forming machine, which adopt a rotating unit which rotatably moves on an endless track a die train having dies with outwardly directed and swingable forming passes in a breakdown step at an early forming stage, and in which the forming pass of each die holds the edge of the workpiece to rotatably move the die by changing the die to a predetermined angle, thereby realizing bending, so that problems due to twisting onto forming rolls and high locally-caused contact stress can be greatly reduced.
