Definitions

  • the present invention relates to a method for producing a hybrid component formed from a cast component and a coupling component according to the features in the preamble of patent claim 1.
  • hybrid components in various fields. This is understood to mean components made from two mutually different materials which, in principle, can not be coupled to one another without problems, for example by thermal joining.
  • a hybrid component can also be understood as meaning components, wherein components are coupled which are basically formed from the same material or similar material alloys, but the component is manufactured successively with two different production methods.
  • connection carrier are coupled at their ends with casting nodes by casting.
  • the side members are poured directly.
  • Object of the present invention is to show a manufacturing method for hybrid components, which is just improved in the connection region of both components and greater shaping degrees of freedom, in particular for the production of Hohlg machinebauieri provides.
  • the sand core is initially provided, which particularly preferably passes through the coupling component.
  • the forming of the sand core can take place, for example, in a core casting machine.
  • the coupling element which is also preferably designed as a hollow component, is then positioned in the core casting machine.
  • the sand is poured in, so that the sand in particular passes through the coupling component, at least this but supporting or supporting is formed.
  • the sand is then consolidated by sand core manufacturing methods known in the art.
  • this can be done by a cold box or other solidification or curing of the sand material, for example with hardening gas.
  • the sand core thus provided thus acts, on the one hand, for the production of the cavity during the actual casting process, and, on the other hand, as a carrier or positioning of the coupling component.
  • the production of the hybrid component is therefore to be understood as meaning that an aluminum casting production method for producing a cast body with an already previously produced coupling component is likewise coupled from an aluminum alloy.
  • the coupling component is preferably an extruded component.
  • the hybrid component here refers to the definition that first the coupling component is self-completed and positioned using the sand core and then cast around with a cast material for the production of the cast component.
  • the coupling component is formed like a ring or sleeve-like.
  • ring is inevitably not here to understand circular, but only that it is designed as a closed hollow component with two open end sides, thus as a sleeve, so that the sand core can pass through the coupling member.
  • the hybrid component itself is particularly preferably provided as an axle auxiliary frame or motor vehicle auxiliary frame.
  • an axle auxiliary frame generally has two cross members and two longitudinal members, wherein particularly preferably at least one cross member acts as a cast component and the coupling components are cast into the cast component for coupling to the longitudinal members.
  • the fixation of the coupling component is thus produced by a positive coupling with the sand core.
  • the sand core provided with the coupling component is then inserted into a casting mold, in particular into a mold.
  • the casting mold is poured out with a casting material which at least partially surrounds the sand core and the coupling component.
  • the coupling component preferably projects at least partially out of the finished cast component.
  • the coupling component is designed as a connection component, then a further element or component can be connected to the protruding part or region, for example by thermal joining.
  • the sand core is discharged, which is carried out in particular by a shaking or shaking.
  • the sand core for example, is blown out pneumatically.
  • the casting itself can be carried out, for example, as a low-pressure or Vakuumkokilleng automatmaschinen.
  • an axle auxiliary frame is produced by the method according to the invention, wherein a cross member of the axle auxiliary frame is produced by casting in each lateral connection points as a cast hollow component.
  • a cross member of the axle auxiliary frame is produced by casting in each lateral connection points as a cast hollow component.
  • the attachment points or vertices also referred to as a node
  • the coupling components are either the longitudinal members of the axle auxiliary frame itself or else designed as a connecting component or connecting flange, so that the actual longitudinal members are then coupled to the connecting flange by a further method step. This is done in particular by thermal joining.
  • the coupling components are for this purpose in particular also made of light metal, in particular as aluminum extruded profiles formed. However, they can also be used as sheet metal forming components, for example, from a steel material, be formed. As a casting material, a steel material or a light metal material is particularly preferably used.
  • the surface of the coupling components is furthermore preferably chemically cleaned before casting and in particular before coupling with the sand core. In particular, this can be done by cleaning with nitric acid or soda. With particular preference, the cavity of the casting tool itself is filled with inert gas. This also avoids the formation of an oxide coating during casting.
  • FIG. 1 shows a Achscousrahmen 1 produced according to the invention as a hybrid component in a schematic plan view.
  • the Achscousrahmen 1 has a cross member, also referred to as a transverse bridge 2, on, according to the invention as Cast hollow component is formed.
  • the transverse bridge 2 passes into two longitudinal members 4, wherein the longitudinal members 4 are in turn coupled to each other via a further cross member 5.
  • the Achscousrahmen 1 is prepared such that initially the side members 4 are coupled to an existing in the transverse bridge 2 sand core 7 and then the transverse bridge 2 is molded onto the sand core 7. After completion of the casting process, the sand core 7 is shaken out.
  • FIG. 2 shows an alternative embodiment variant FIG. 1 , wherein shown here in the coupling point 3, a Anitatisflansch 6 is poured.
  • the connection flange 6 is thus first produced by casting with the transverse bridge 2, wherein after completion of the casting process and / or shaking the sand core 7, the side members 4 are then coupled to the Anitatisflansche 6 and joined, for example, with these cohesively.
  • FIG. 3 shows a cross-sectional view along section line III-III of FIG. 1 , It can be clearly seen here that the transverse bridge 2 is designed as a hollow component, here represented as a partially open c-shaped component in cross section. This is achieved by first providing a sand core 7 and, coupled with the sand core 7 in an interlocking manner, bringing an end region of the longitudinal member 4 illustrated here into connection. The longitudinal member 4 is thus inserted with the solidified sand core 7 in a mold and cast around casting material, so that the transverse bridge 2 is formed by the cast material. Subsequently, the sand core 7 is shaken out.
  • FIG. 4 shows a side view of a sand core 7 according to the invention, which is positively coupled to a connecting flange 6.
  • FIG. 5 shows a longitudinal sectional view through the illustration according to FIG. 4 , Good to see in the FIGS. 4 and 5 in that the sand core 7 engages in a form-fitting manner through the connecting flange 6, thus the coupling component.
  • the Anitatisflansch 6 is fixed in position and can not slip by introducing the cast material during the casting process.
  • the sand core 7 has, on the image plane shown on the left side of an area which according to the formation of the cavity FIG. 3 in the transverse bridge 2 is used.
  • the illustrated on the image plane right part of the sand core 7 is used during the casting process for placement in the casting mold and / or for sealing the cavity from the environment.
