Definitions
- the invention relates to a method for pouring a metallic Semifinished product in a cast component according to the generic term of claim 1.
- the object of the invention is to the adhesion of inserts over the prior art to improve and cost-effectively.
- the method according to the invention according to claim 1 consists in that an insert before insertion into a casting tool roughened by high pressure water jets. By the high pressure water jetting the surface will be cleaned and it will be advantageous undercuts on the surface of the insert which leads to a good clamping of the cast metal lead after its solidification.
- the insert is preferably a metallic insert. Under certain conditions and surface properties can also use intermetallic components; Carbide, metal-ceramic composites, Metal matrix composites (MMC), intermetallic ceramic composites, Ceramics or inorganic Natural materials are used as inserts
- the roughening of the surface according to the invention is preferably carried out by one or more flat jet nozzles that are elliptical Opening has.
- Such nozzles deliver in contrast to full jet nozzles with a circular opening to one expanded surface beam and a groove-free Surface.
- the application of several nozzles reduced at the same time the processing time.
- an exit angle of the high pressure water jet between 20 and 34 °.
- a particularly convenient way the surface economically and quickly roughen is the application of a field of jets, which are preferably arranged perpendicular to the surface.
- Methods are hypereutectic aluminum-silicon alloys.
- Semi-finished products made of such materials have hard silicon rich phases and relative to the surface soft aluminum rich phases.
- the hard, silicon-rich Phases are torn out by water jetting 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 pretreated cylinder liner is in a die casting tool positioned on quills, the tool is closed and a resulting mold cavity, which is a cylinder crankcase depicts is pressurized (about 800 bar) filled with a liquid aluminum alloy (AlSi9Cu3).
- AlSi9Cu3 a liquid aluminum alloy
- the aluminum flows around the cylinder liner and penetrates into the areas of the undercuts 13 on.
- After solidification of the aluminum creates a solid Clamping between the solidified aluminum and the surface the cylinder liner (interface).
- the adhesive strength this interface is twice as high as one Interface with sandblasted surface of the insert.
- the method according to the invention can be applied to all common casting methods, where inserts are pourable applied become. These include, in particular, conventional die-casting, squeeze casting, thixocasting, thixomolding, chill casting, Sand casting, precision casting and, if appropriate, temperature-resistant Inlay all types of iron casting.
- the parameters mentioned in the previous example are on optimized for a specific application. Depending on the application the parameters may vary as follows.
- the distance between the nozzle opening and the surface of the insert can be between 10 mm and 30 mm.
- the pressure of Water jet is between 1500 bar and 2000 bar, the exit angle between 25 ° and 34 °.
- the rotation speed of the insert is between 100 and 1000 / min, where the feed rate of the nozzle or the nozzle field varies between 2 mm / s and 50 mm / s.
- the last two parameters are especially important for the nature of the surface, namely the shape and Frequency of undercuts, the microscopic surface roughness and the macroscopic flatness (avoidance of groove formation).
- the shape and Frequency of undercuts namely the shape and Frequency of undercuts, the microscopic surface roughness and the macroscopic flatness (avoidance of groove formation).
- the microscopic surface roughness namely the shape and Frequency of undercuts, the microscopic surface roughness and the macroscopic flatness (avoidance of groove formation).
- For non-rotationally symmetrical inserts is due to a rotation of the insert during the Water jet dispensed.
- the nozzle array or single nozzle is conventional Systems for high-pressure water jetting with thick and difficult to move Supply lines connected.
- the free movement the nozzles is therefore limited.
- the insert part to be irradiated relative to the nozzle field or to move to the nozzle. In a simple case occurs this, as described in the example, by rotation. In in other cases, the relative movement is carried out by a suitable Facial expressions or by robots.
