Method for producing a thin-walled rotationally symmetric component from aluminium or an aluminium alloy

Abstract

A method for producing a thin-walled rotationally symmetric component from aluminium or an aluminium alloy in a die-casting process. The die-casting process operates with a double casting cavity, in which the shell of the component is produced without recesses, and the recesses are made in the shell by cutting.

What is claimed is: 
     
         1 . A method for producing a thin-walled rotationally symmetric component from aluminium or an aluminium alloy, the method comprising:
 performing a die casting process using a double casting cavity to produce a shell of the component without recesses; and   delivering shells to a cutting unit;   clamping the shells; and then providing recesses on a peripheral surface of the shells by cutting.   
     
     
         2 . The method of  claim 1 , wherein the cutting takes place before or after a metal cutting of the component shell. 
     
     
         3 . The method of  claim 1 , further comprising turning the shells at a respective inner surface thereof, and then turning the shells at a respective outer surface thereof. 
     
     
         4 . The method of  claim 1 , wherein clamping the shells comprises clamping against bearing surfaces of the shells on a respective inner surface thereof, and then clamping against bearing surfaces of the shells on a respective outer surface thereof. 
     
     
         5 . The method of  claim 1 , further comprising forming bearing surfaces using tooth flanks of an inner tooth, the tooth flanks serving as a bearing surface. 
     
     
         6 . The method of  claim 5 , wherein the tooth flanks define a positioning of the cylindrical components on a supporting surface of a production line. 
     
     
         7 . The method of  claim 6 , wherein the positioning of the components take place in a metal cutting station, a bearing cutting station and a measurement-based registration station. 
     
     
         8 . The method of  claim 6 , wherein the positioning is realized via cast-on bosses on the components. 
     
     
         9 . The method of  claim 1 , wherein the cutting comprises moving the components both radially and axially in a direction of the longitudinal axis. 
     
     
         10 . The method of  claim 1 , wherein the cutting comprises laser cutting, water jet cutting, or drill head cutting.
