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： To improve forming performance in a smart mill allowing implementation of required forming by moving a forming tool arranged in a stand of a pipe mill automatically to a predetermined position.
Non-drive type breakdown rolls BD exclusive to bending are arranged in multiple stands. Drive roll DR stands exclusive to driving are arranged in stages in front of and behind each DR stand. The drive roll DR is configured to apply thrust to a central portion of a raw material using an upper flat roll and a lower flat roll, and has thrust control means and driving rotation number control means for applying thrust required for passage through the step using the drive rolls DR in multiple stages entirely and controlling the thrust. Applying the thrust under pressure control to the central portion of the material using the upper and lower flat rolls at the DR stand provides a definite roll reference diameter and feeds the raw material at a constant speed and thrust, making it possible to ensure thrust required for various product diameters or thicknesses.-

摘要： In a method for manufacturing a metal pipe from a metal plate using a forming tool, the position of the tool is optimized simply and correctly by incorporating individuality of the raw material plate into setting of the tool position.
As a preparatory stage, a forming process is analyzed by simulation for each plate. Based on result of the analysis, correlation between a deformed shape value of a raw pipe and tool position information is acquired. Then, the forming process for each plate is stored as correlation between the deformed shape value of the raw pipe and the tool position information. During pipe manufacturing, a deformed shape value of the raw pipe is measured actually while a plate is passed. On the basis of the actually measured deformed shape value, a forming process for the raw pipe is expected and assumed (by using the correlation). Tool position information necessary for implementing the expected and assumed forming process is retrieved from the stored correlation. The retrieved tool position information is realized at a stand array.-

摘要： [Problem to be solved] To provide a squeeze device of excellent economic efficiency and excellent workability for electric resistance welded pipe manufacturing having a simple configuration, achieving size reduction and weight reduction easily, and allowing operation in roll changing to be performed simply.
[Solution] The squeeze device includes: a U-shaped fixed stand 10 with an open top; and a slidable roll support plate 60 inserted into the U-shaped fixed stand 10 through the open top of the U-shaped fixed stand 10 and held in the U-shaped fixed stand 10 in a manner allowing taking off of the roll support plate 60. The roll support plate 60 supports right and left side rolls 40 in a pair and an upper roll 50 on an upstream-side main surface in a manner allowing the side rolls 40 and the upper roll 50 to move in screw down directions. The roll support plate 60 has space 61 for passage of the pipe-shaped material formed at a position surrounded by these rolls. The space 61 is a part of a cutout-shaped opening opened toward a lower edge of the roll support plate 60. Each of the right and left side rolls 40 in a pair is a tilted roll with a corresponding roll shaft 42 tilted outwardly toward a higher position.-

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.
