An insert including a taper is covered with a molten metal. A metal molded product with the insert joined thereto is generated by semi-cooling the molten metal to a press-fitting temperature which is higher than a recrystallization temperature of the molten metal and lower than a melting point of the molten metal. A fitting hole which is filled with the insert is formed in the metal molded product. The taper is fitted into the fitting hole. An undercut is not formed in front of a tip of the taper. The insert is press-fitted into the fitting hole while pressing and extending the fitting hole with the taper in a thinning direction of the taper at a press-fitting temperature. The metal molded product is further cooled with the press-fitting maintained.

The present invention provides a forging and pressing production management method, comprising the steps of: A. acquiring at least one characteristic of a fed material; B. correspondingly selecting, according to the characteristic of the material, at least one of the temperature, the pressure or a mold from among operating factors of the forging and pressing process; C. transporting the material according to the selection result; and D. processing the material until a finished product is produced. The present invention enables at least one material to be formed by hot melt and forging and pressing by itself without human operation, thereby completing the mass production of the material. Operating factors such as the pressure, temperature and mold required for formation are taken into account, and the identification requirements for the material are reduced, thereby realizing large-scale production.

The invention relates to a tool for realising a press quenching and tempering method for a rotational symmetric tool, in particular for a gear wheel, wherein the tool is at least in part manufactured as an additive and wherein, in an additively manufactured area of the tool, is formed at least one pipe for guiding a fluid.

A forge and method of forging is provided. The forge converts an asymmetric railroad rail to a symmetric railroad rail through a combination of vertical and horizontal forging operations. The rail is linearly translated to heating and forging stations on a roller table. The asymmetric to symmetric conversion can be completed without the need for reorienting the rail except along a single translational axis.

A press comprising: at least one press ram by means of which a press stroke can be carried out when the press is actuated; at least one first working station and a second working station, wherein the first and the second working station each has a tool lower part and a tool upper part, wherein a first forming stage is formed by means of the tool lower part and the tool upper part of the first working station, and a second forming stage is formed by means of the tool lower part and the tool upper part of the second working station; and a mechanical element for transmitting the press stroke to one of the first or second forming stages, wherein the press stroke can be transmitted to the first and the second forming stages independently from one another.

A kit for forming a forge table and a forge pot for use therewith to carry a fuel for combustion so as to generate heat for heating a metallic workpiece. The forge table includes a tabletop with a central opening for receiving the forge pot. The forge pot includes a container for supporting the fuel and an air chamber fluidically communicated with the container and including an opening for fluidic communication with an external airflow source which generates an airflow for subsequent conveyance to the container for combusting the fuel. Each kit comprises interconnectable components made from rigid non-combustible sheet material. The airflow source is mounted in fluidic communication with the chamber and there is provided an intermediary valve component supported on the same mounting pegs carrying the source that is movably supported on the pegs so as to be operable to control passage of the airflow to the chamber.

There is provided a press device which causes a slide to advance and retreat to forge a forming object by using a die heated to a predetermined temperature. The press device includes a determination unit that determines whether or not a press operation enters a stable forging period during which a mechanical load acting on the slide in a press direction is stable, and a controller that adjusts a force acting on the forming object from the die to deform the forming object, based on a predetermined measurement value, when the determination unit determines that the press operation enters the stable forging period.

A method and a plant for manufacturing fasteners, in particular screws, along an automated production line; the method comprising the following steps: feeding the raw material made of titanium; heating the raw material to a predefined temperature; cutting one or more pieces of a predefined length, in succession, from the heated raw material; deforming plastically each piece by means of one or more finishing stations, so as to obtain a fastener; heating, during the deforming step, the material that passes through each workstation to a predefined temperature; wherein the material manipulated along the production line during the feeding, heating, and deforming steps is automatically transported along the production line.
