The system may include a controller in electronic communication with the mechanical arms, the spray nozzles, the thermocouples, and the non-contact temperature sensors, that is configured to initiate a quenching process, receive temperature data, analyze the temperature data to determine a temperature difference value, determine that the temperature difference value exceeds a threshold temperature difference value, and adjust the quenching process if the temperature difference value exceeds the threshold temperature difference value.

Certain exemplary embodiments can provide a manufacturing method, process, machine, and/or system for continuously consolidating granular materials, creating new alloys and/or composites, and/or modifying and/or refining material microstructure, by using plastic deformation of feedstock(s) provided in various structural forms. Materials produced during this process can be fabricated directly and/or in forms such as, e.g., wires, rods, tubes, sheets, plate and/or channels, etc.

Production of a bulk Al-RE alloy body (product) using cast billets/ingots (cooling rates <100 C/s) or rapidly solidified Al-RE particulates (cooling rates 10.sup.2-10.sup.6° C./second) that have beneficial microstructural refinements that are further refined by subsequent consolidation to produce a consolidated bulk alloy product having excellent mechanical properties over a wide temperature range such as up to and above 230° C.

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.

An extrusion machine includes a main frame, a friction wheel, a tool holding device, a locking device and a tool unit supported on the tool holding device. Furthermore, a shielding unit with at least one first nozzle and at least one second nozzle is provided, wherein the nozzles are formed to emit a gas which is free of gaseous oxygen. The first nozzle is directed at a peripheral portion of the friction wheel. The second nozzle is arranged below a stripping area of the tool unit. Further, an extrusion machine has a sensor unit between the tool holding device and the tool unit and a method controls distance between two tool components of the extrusion machine. Furthermore, different extrusion machines as well as methods for changing friction wheels are provided.

The invention relates to a press for extruding metal material. The press comprises a hydraulic oil circuit for controlling one or more extrusion pistons movable within corresponding cylinders. Such a circuit comprises a fixed displacement, circulation pump operated by an electric motor with variable rotation speed. The hydraulic circuit comprises a main line and a branch line, along which a shutoff element is arranged. The hydraulic circuit comprises a hydraulic control unit comprising a pilot valve arranged along a pilot line provided with a first segment communicating with the main line and a second discharging segment. Said hydraulic unit is provided to move the shutoff element between an opening position and a closing position of the branch line according to the difference between the oil pressure upstream of the shutoff element and that in the first segment of said pilot line. The hydraulic circuit further comprises a control element which, in an activation condition, and as a result of the activation of said pilot valve, determines a gradual increase of the pressure in the first segment of said pilot line and a corresponding gradual closing movement of said shutoff element causing a consequent gradual increase of the thrust on the piston until the reference speed is reached.

An extrusion press device according to the present invention includes: an extrusion unit that includes a container configured to store an extrusion material and an end platen configured to support a die-from which the extrusion material is extruded; and a control unit configured to control operation of the extrusion unit, including container sealing force that presses the container against the die. The control unit performs control to apply complementary pressure corresponding to reduced container sealing force that is increased along with progression of extrusion, to the container in a direction of the extrusion during a period from start to completion of the extrusion.

One or more hollow billets are loaded onto an elongate mandrel bar for extrusion. The billets are transported along the mandrel bar to a rotating die. The billets are transported through fluid clamps, which engage the mandrel bar and provide cooling fluid to the mandrel bar tip, and through mandrel grips, which engage the mandrel bar and prevent the mandrel bar from rotating. One or more press-rams advance the billets through a centering insert and into the rotating die. A quench assembly is provided at an extrusion end of the extrusion press to quench the extruded material. A programmable logic controller may be provided to control, at least in part, operations of the extrusion press system.
