Definitions

  • the invention relates to a method for producing a channel, in particular a hydraulic flow channel, in a workpiece made of cast steel, gray or spheroidal cast iron or a cast alloy, and to such a cast workpiece provided with a channel.
  • the manufacturing effort should be kept extremely low, but above all the shape of the channel should be arbitrary and thus to be designed to be aerodynamically efficient and also to be used for media which are under high pressure without this being able to escape. It is also an object of the invention to provide a workpiece provided with such a channel.
  • the method for producing such a channel in a cast workpiece is characterized in that a metal component, provided with the channel and having two or more parts in cross-section, is inserted into the mold before the introduction of the melt, and is partially cast into the workpiece is shed.
  • a tube preferably of circular cross section, formed from two or more hollow bodies arranged one inside the other can be inserted into the mold, but it is also possible to provide a hollow body consisting of materials with different melting points as the metallic component.
  • the metallic component In order to be able to establish a pressure-tight connection of the channel to a pressure medium line, the metallic component should furthermore be axially recessed at one or both ends in its outer region in such a way that it is partially enclosed on the front side by the potted material of the workpiece.
  • the workpiece formed according to the invention from steel, gray or spheroidal cast iron or a cast alloy with a channel provided in this, in particular a hydraulic flow channel, is characterized in that in this a metallic, the centrally arranged channel having two or two cross sections multi-part component is cast.
  • the metallic component can be formed from two or more tubes arranged one inside the other, preferably with a circular cross section, the inner tube made of alloy steel, for example chromium-nickel steel, made of copper, brass or a similar material and one or more of those connected to the workpiece outer tubes are made of steel.
  • alloy steel for example chromium-nickel steel, made of copper, brass or a similar material
  • this can also be composed of materials with different melting points.
  • the channel can be shaped in any way and thus designed to be streamlined and is also extremely true to size. If, in the mold, a metal component with two or more parts, which is provided with the channel and which is poured into the workpiece or partially cast with it, is inserted into the mold, the inner part of the component retains despite the high temperatures and which occur during casting of the workpiece the high pressure load its shape.
  • the outer part of the metallic component melts in whole or in part and thus creates a firm connection between the workpiece and the inner part of the metallic component, but deformations of the channel are thereby reliably excluded, since the inner part of the metallic component is protected from melting . This is due to the fact that the inner part of the metallic component absorbs only a small amount of thermal energy, this is rather retained by the outer part, so the heat gradient is large.
  • the channel can thus also be formed from a copper or brass tube.
  • the channel is extremely pressure-tight, even at high pressures, depending on the material of the inner part used, regardless of the cast material; Accordingly, a poor quality cast material can often be used.
  • the cast workpiece Due to the component having the channel, the cast workpiece is also solidified to a considerable extent.
  • the cast-in metallic component which forms an intimate bond with the material of the workpiece, and the parts of which fuse together or onto one another
  • the cast workpiece shown in FIG. 1 and designated 11 is designed as a kingpin and is provided with a channel 13 in its leg, the shape of which is designed to carry out lubricant.
  • a two-part metallic component 12 is cast into the workpiece 11, which consists of the two tubes a and b placed one inside the other.
  • the outer tube b is partially melted by the cast material of the workpiece 11 and thus connected to it, and this is also shrunk onto the inner tube a, so that the metallic component 12 is held firmly in the workpiece 11.
  • the ends of the metallic component 12 are each protruding into the mold over the associated end wall of the workpiece 11, so that no melt can get into the channel 13 and does not scale.
  • the metallic component 12 is held in such a way that it can expand in the longitudinal direction, so that tensions and the resulting deformations are excluded.
  • Metallic components 22, 22 'and 22 are cast into the casting workpiece 21 shown in FIGS. 2 to 4, which are of different designs and each have a channel 23.
  • the outer tube b is reset in the region of the end wall of the casting tool 21, so that its material is directly connected to the inner tube a. Since a workpiece cools more rapidly in the edge area than in the inside, it is also impossible in this embodiment that the inner tube a melts.
  • the metallic component 22 'cast into the workpiece 21 consists of materials a' and b 'with different melting points, according to FIG. 4 the metallic component 22 "is formed from three tubes a", b "and c" arranged one inside the other .
