Definitions

  • the invention relates to a method for pouring a metallic semifinished product into a cast component according to the preamble of claim 1.
  • Cast components in particular light metal cast components are often reinforced by inserts that are integrated by pouring into the component. These inserts represent local material improvements such. B. better wear resistance, higher mechanical strength or thermal resistance.
  • the object of the invention is to improve the adhesion of inserts over the prior art and to make cheaper.
  • the inventive method according to claim 1 is that an insert is roughened by high pressure water jets prior to insertion into a casting tool.
  • the high-pressure water jetting the surface is cleaned and there are produced advantageous undercuts on the surface of the insert, which lead to a good clamping of the cast metal after its solidification.
  • the insert is preferably a metallic insert. Under certain conditions and surface properties also intermetallic components; Carbide, metal-ceramic composites, metal matrix composites (MMC), intermetallic ceramic composites, ceramics or inorganic natural materials can be used as inserts
  • the roughening of the surface according to the invention is preferably carried out by one or more flat jet nozzles, which has an elliptical opening.
  • Such nozzles in contrast to full-jet nozzles with a circular opening, provide an expanded surface jet and a groove-free surface. The use of several nozzles at the same time reduces the processing time.
  • an exit angle of the high-pressure water jet between 20 and 34 °.
  • a particularly convenient way to roughen the surface economically and quickly is to use a field of nozzles that are preferably perpendicular to the surface.
  • Hypereutectic aluminum-silicon alloys Very suitable for roughening the surface according to the inventive method are hypereutectic aluminum-silicon alloys.
  • Semi-finished products made from such materials have hard silicon-rich phases on the surface and relatively soft aluminum-rich phases.
  • the hard, silicon-rich phases are torn out by the water jets and leave the desired undercuts on the surface.
  • the distance 9 between the nozzle opening and the cylinder liner 5 is 12 mm.
  • the rotational speed of the cylinder liner 5 is 600 revolutions per minute.
  • the nozzle field 1 describes a longitudinal movement along the longitudinal axis of the cylinder liner at a speed of 10 mm / s.
  • the blasting medium water contains a neutral cleaner with a concentration of approx. 1.5%.
  • the jet medium emerges from the nozzle 3 in the form of a water jet 7 and describes an opening angle ⁇ of 30 °.
  • the water jet 7 has at the outlet from the nozzle opening to a pressure of 1900 bar.
  • a surface 11 is generated, as shown in Fig. 2 .
  • the surface 11 has undercuts 13, which results from the breaking out of silicon-rich phases, not shown here.
  • the average roughness Ra of the surface thus produced is 8.4 ⁇ m, the average roughness Rz is 55.3 ⁇ m.
  • the thus pretreated cylinder liner is positioned in a die casting tool on quills, the tool is closed and a resulting mold cavity, which forms a cylinder crankcase, under pressure (about 800 bar) with a liquid aluminum alloy (AlSi9Cu3) filled.
  • AlSi9Cu3 a liquid aluminum alloy
  • the aluminum flows around the cylinder liner and penetrates into the regions of the undercuts 13.
  • After solidification of the aluminum creates a firm clamping between the solidified aluminum and the surface of the cylinder liner (interface).
  • the adhesive strength of this interface is twice as high as that of a sandblasted surface interface of the insert.
  • the method according to the invention can be applied to all common casting methods in which inserts are pourable. These include, in particular, conventional die casting, squeeze casting, thixocasting, thixomolding, chill casting, sand casting, precision casting and all types of iron casting with temperature-resistant inserts.
  • the parameters mentioned in the previous example are optimized for a specific application. Depending on the application, the parameters can vary as follows.
  • the distance between the nozzle opening and the surface of the insert may be between 10 mm and 30 mm.
  • the pressure of the water jet is between 1500 bar and 2000 bar, the exit angle between 25 ° and 34 °.
  • the rotational speed of the insert is between 100 and 1000 / min, wherein the feed rate of the nozzle or the nozzle array varies between 2 mm / s and 50 mm / s.
  • the nozzle field or the single nozzle is in conventional plants for high-pressure water jetting with thick and difficult to move Supply lines connected.
  • the free movement of the nozzles is therefore limited.
