摘要:
A metal 3D printer is disclosed for fabricating metal articles by depositing molten metal onto a print bed. The metal 3D printer has a print head having a crucible and nozzle. The crucible melts metal and the nozzle deposits the molten metal onto the print bed. The 3D printer further includes an induction heating system to heat the print head and a heated print bed disposed below the nozzle. The metal 3D printer also has a computer numerically controlled (CNC) gantry for moving the print head and the print bed relative to each other along X, Y, and Z axes. Shielding gas may be directed proximate to the crucible or the nozzle. The feedstock for the printer may be a plurality of wire strands braided together. A mesh overlay may be positioned on top of the print bed.

摘要:
The invention relates to an induction head (1) for welding multilayer stacks (48) for printed circuits and the like, wherein an inductor core (3) associated with an excitation inductance (6) is cooled by air or another gaseous fluid, which circulates in a path provided in the induction head. A second inductor core (4) cooperates with the first one to guide a magnetic flux to at least one junction area of a multilayer stack (48) interposed between the cores (3, 4): the cooling fluid laps the junction area of the multilayer stack, thus facilitating the detachment of the head at the end of the welding process.

An induction heating apparatus includes a susceptor defining a reaction chamber. A housing is spaced from the susceptor opposite the reaction chamber and defines a port. A void space is defined between the housing and the susceptor. An induction coil extends through the port and is disposed within the void space for conducting an electric current to heat the susceptor to heat the reaction chamber. A flange comprises a metal material and is coupled to the housing at the port for sealing the port with the induction coil extending through the flange. An isolator is disposed between the flange and the housing to prevent the electric current from passing into the housing.

L'invention concerne un moule comprenant une première partie (101) comportant une carcasse (111) sur laquelle est rapportée une zone moulante (112) constituant une interface (115) mécanique entre ladite zone moulante et la carcasse, et comportant des inducteurs (132) s'étendant selon une direction dite longitudinale dans des cavités (131) entre ladite interface (115) et la zone moulante (112) et un dispositif de refroidissement (140) s'étendant à l'interface entre ladite zone moulante et la carcasse.
摘要:
A device is described for magnetic heat induction and subsequent heat exchange to mobile streams of matter. The device can provide efficient heating of moving gaseous, liquid, or solid masses. A cold mass is made to flow past an induction heated workpiece, whereby the cold mass becomes heated via thermal transfer from the workpiece to the cold mass. The device can include a material susceptible to heating by magnetic induction that is inserted into a tube or other containment structure. The tube can be the transport conduit for the material to be heated. An induction coil can surround the tube. The coil can be connected to a high energy LC (inductance-capacitance) resonance circuit. Resonance generates magnetic flux in the coil. The flux can interact with the workpiece inside the tube. Heat can be generated in the workpiece and can then be transmitted to the cold mass as it is conveyed past the workpiece.

Eine Induktionsheizeinrichtung (11) für eine Kochstelle einer Kochfeldmulde (50) ist als autarke Baueinheit ausgebildet. Dazu weist sie eine Trägereinrichtung (20) auf, welche neben der Induktionsspule (13) einen Bauteilträger (31) mit Leistungselektronik (33) und Steuerelektronik (37) trägt. An diese Induktionsheizeinrichtung (11) sind lediglich Steueranschlüsse (59) für Steuersignale hinsichtlich der Leistungsbeaufschlagung sowie eine direkte Verbindung zu einem Netzanschluss (57) vorzusehen. Die Steuerelektronik (37) übernimmt selber die Leistungsbeaufschlagung an der Leistungselektronik (33). Vorteilhaft sind diese Induktionsheizeinrichtungen (11) von den äußeren Abmessungen aufgebaut wie herkömmliche Strahlungsheizkörper (55).
摘要:
An apparatus and method to complete a lateral wellbore that can be utilized for existing or new wells. The apparatus can be set in tension with positive confirmation on surface of correct orientation and position. Additionally, the apparatus does not restrict the internal diameter of the liner or the central wellbore and permits full access to both the lateral and the primary wellbore below the junction. The invention includes a tie back assembly (140) disposed at an upper end of a liner string (135). The tie back assembly (140) includes a hanger (150), a packer (145) and a tubular housing (175). The housing includes a liner window (155) formed in a wall thereof to permit access to the lower primary wellbore. An inner tube (185) is disposed within the housing and includes a key (180) disposed on an outer surface for alignment with a window (105) formed in a wall of the casing and a no-go obstruction (190) with is constructed and arranged to contact a lower portion of the casing window to axially locate the tie back assembly in the primary wellbore.

The invention relates to a shrinking device (1) for shrinking a rotary tool (5) into a central receiving opening of a toolholder (3) which holds said rotary tool (5) in a press fit. The device comprises an induction heating device (15, 18) for thermally expanding the toolholder (3) in the area of the receiving opening. A cooling device (51, 53) with at least one cooling collar (53) which can be placed on the toolholder (3), in physical contact with the same, and through which a liquid coolant can flow, is provided for cooling the receiving opening area of the toolholder. This liquid cooling considerably reduces the overall time span needed for the shrinking process.
