An apparatus for forging a hollow body from a pre-perforated hollow block includes forging tools that can be driven radially in relation to a forging axis, a clamping head which is displaceable on a guide bed in the direction of the forging axis and includes collet chucks for the hollow block, and a mandrel carriage which is arranged on the side of the clamping head facing away from forging tools, which is displaceable independently of the clamping head along the guide bed, and whose mandrel bar provided with the forging mandrel penetrates the clamping head coaxially to the forging axis. In order to provide advantageous constructional conditions the mandrel carriage includes an axial actuating drive for the mandrel bar and can be coupled in a tension-proof manner to the clamping head.

A forging die device is provided with an upper die 10 and a lower die 20. At least one die 10 (20) of the upper die 10 and the lower die 20 has a die holder 12 (22) which surrounds the outer periphery of the die 10 (20) and holds the die 10 (20). The die holder 12 (22) is configured to bear the radial tensile stress (tensile force) received by the die 10 (20) during forging. By this means, the die 10 (20) can be miniaturized.

A manufacturing method of press-molded article of the present invention comprises a step of placing a member to be pressed in a press molding apparatus and a step of pressing a flat plate portion of the member to be pressed by bringing a first press portion and a second press portion closer to each other. A first opposing surface and a second opposing surface, while facing to each other, keep in contact with the flat plate portion during pressing. In the press step, a thick part is formed on the flat plate portion by allowing a part of a material of the flat plate portion to flow, in a press direction, into a thickened portion-forming section formed on the first opposing surface. The second opposing surface is moved to the press direction as the flat plate portion is pressed by the first press portion and the second press portion.

A pipe fabrication apparatus includes a fabrication module having a guide adapted to support a cylindrical component, at or adjacent a first end of the component, at two discrete and space apart locations on an exterior surface of the component, and a bed for supporting the cylindrical component at a position distal the first end such that a longitudinal axis of the component is aligned with a central axis of the fabrication module in order to allow additional cylindrical parts to be quickly and easily coaxially aligned with the component for the purposes of tack welding the two items together prior to full seam welding.

A forging die device is configured in such a manner that die heating heater plates 11, 21 are disposed respectively between a die 1 which is held at the outer periphery by die holders 12, 22, and die holding means 14a, 24a composed of heat insulating plates 13, 23 and die plates 14, 24, and the die holders, the die holding means and the die plates are integrated together. After the preheated die 1 is placed on the heated die holding means, the die 1 is heated by heating means, and forming surfaces 10a, 20a of the die are heated to a required temperature immediately before forging.

This document presents a system and method for presenting the invention as a tool that provides the ability to bend and shape rebar type material with less stress on the human body aiding in preventing common injuries that occur from standard rebar tools and processes and it provides portability so that all work can be done at the job site saving time and money from having to go to a workshop to fabricate unique shaped rebar parts.

A processing line material clear out devices and methods are disclosed. The device is particularly useful for clearing metal billets from induction heating units, but may be used for many other processes having sequentially ordered materials traveling down a conveyor or other processing line. In one example of the invention, a reciprocating push rod rack is used to sequentially deposit and remove at least two push rods used to abut and clear the downstream billets. A push rod advance device is used to interlink independent, sequential push rods positioned on the billet track. On clearing of the billets, the push rods are retracted, removed from the billet track and stored on the push rod rack for ready use.
