An electric fan includes a plurality of blades and an electric motor for rotating the blades. The electric motor includes a stator and a rotor rotatable relative to the stator about an axis. The rotor includes a backing ring and a diecast rotor can. The can includes a non-machined sidewall that is diecast integrally as part of the rotor can. The sidewall extends about the axis. The rotor can is diecast in an overlying relationship with at least part of the backing ring, with the sidewall and backing ring being securely interengaged so as to restrict relative shifting therebetween.

Method for the aluminothermic welding of rails, involving the steps of: —triggering an aluminothermic reaction in a crucible, —pouring the metal resulting from said reaction into the mold so as to fill the molding cavity from the rail flange, —after filling the cavity, triggering a second aluminothermic reaction above the rail head, and pouring the metal resulting from said reaction into the cavity in the region of the rail head. The mold used in the method is designed to fit over the ends of two rails to form a molding cavity comprising a crucible positioned above the rail head region so that it can be fed with molten metal of the cavity via a secondary passage.

A metering unit (14) for molten lead is paired with the molding cavity (13) of a molding block (6). The metering unit (14) includes a cylinder (1), to which molten lead is supplied via a blockable line (8), and a piston (2), which can be lifted in order to transfer molten lead into the molding cavity (13) in order to cast pole connectors onto battery plate lugs.

A brake component for a motor vehicle may include a body and at least one cable positioned within the body. The at least one cable may include a plurality of wires positioned relative to one another, each of the plurality of wires having a surface in sliding contact with surfaces of adjacent wires of the plurality of wires. During braking of the motor vehicle, sliding movement of the surfaces of the plurality of wires relative to each other may dampen a resonant frequency of the component.

A method for integrally forming a non-metal part (50) and a metal part (60). The method comprises the following steps: A, arranging the transparent non-metal part (50) in a mold; B, arranging the metal part (60) on the periphery of the non-metal part (50) in the mold, the metal part being a continuous structure located on the periphery of the non-metal part (50); C, heating the metal part (60) so that the metal part (60) is formed into semi-solid metal defined in a mold cavity; D, extruding the semi-solid metal through the mold, so that the semi-solid metal is combined with the periphery of the non-metal part (50) in a seamless mode; and E, quickly cooling the semi-solid metal located on the periphery of the non-metal part (50), so that the semi-solid metal is formed into amorphous metal combined with the periphery of the non-metal part (50) in a seamless mode. The method is simple and practicable, the rate of finished products is high, the metal part obtained through extrusion has high compactness and strength, and the difficulty in follow-up surface treatment of the metal part is reduced.
摘要:
A metal casting has a metal casting base body into which at least one metal insert body (1) is cast. The metal insert body has anti-twisting part-contours and is connected to the metal casting base body in a positively locking manner by the casting-in. To simplify the production of a stable metal casting, the metal insert body (1) has an elongate shape with a longitudinal axis and an outer mold contour with an unround cross section interrupted in the longitudinal direction by annular grooves (11-13) that fix the cast-in metal insert body (1) in the axial direction.

A method for forming a control arm is provided. The method includes providing an insert and a mold and also includes overcasting the insert within a metal in the mold. The insert defines a recess that is shaped for receiving a mating component. After the insert is overcast within the metal, the mating component may be positioned or mounted within the recess of the insert. A related control arm is also provided.

Methods for manufacturing a turbine nozzle are provided. A plurality of nozzle segments is formed. Each nozzle segment comprises an endwall ring portion with at least one vane. The plurality of nozzle segments are connected to an annular endwall forming a segmented annular endwall concentric to the annular endwall with the at least one vane of each nozzle segment extending between the segmented annular endwall and the annular endwall.
