Method for producing a shaped part, and a shaped part

Abstract

A method for producing a shaped part may include providing a first layer consisting of a first sheet metal material and at least a second layer consisting of a second sheet metal material, forming a preliminary composite comprising the first layer and the at least second layer, plating the preliminary composite, and forming the preliminary composite to obtain the shaped part using a flow turning, compression or deep drawing method. The plating may be done before or during the forming process. At least one of the first layer or the second layer may be heated for the plating and/or the forming. The shaped part may be formed by compressing the preliminary composite with a pressing body, and the pressing body may be moved parallel or perpendicular to an axis of symmetry during the compression.”

         13 . A method for producing a shaped part, the method comprising:
 providing a first layer comprising a first sheet metal material and a second layer comprising a second sheet metal material;   forming a preliminary composite that includes the first layer and the second layer;   plating the preliminary composite; and   forming the preliminary composite to obtain the shaped part by way of flow turning, compression, or deep drawing,   wherein plating the preliminary composite is performed before or during the forming of the preliminary composite to obtain the shaped part.   
     
     
         14 . The method of  claim 13  comprising heating at least one of the first layer or the second layer for the plating. 
     
     
         15 . The method of  claim 13  wherein the preliminary composite is formed such that the shaped part is rotationally symmetrical to an axis of symmetry at least in some regions. 
     
     
         16 . The method of  claim 15  wherein the shaped part is formed by compressing the preliminary composite with a pressing body, wherein the pressing body is moved parallel or perpendicular to the axis of symmetry during the compression. 
     
     
         17 . The method of  claim 13  wherein the first sheet metal material is different than the second sheet metal material. 
     
     
         18 . The method of  claim 17  wherein the first sheet metal material and the second sheet metal material are comprised of an iron material. 
     
     
         19 . The method of  claim 17  wherein the first sheet metal material and the second sheet metal material are comprised of a nonferrous material. 
     
     
         20 . The method of  claim 13  comprising securing the first layer and the second layer for the plating. 
     
     
         21 . The method of  claim 13  comprising positioning the preliminary composite in a die. 
     
     
         22 . The method of  claim 21  comprising clamping the preliminary composite in the die by way of a spring element. 
     
     
         23 . The method of  claim 13  comprising positioning the preliminary composite in an at least partially-contoured receiving region of a die for the plating. 
     
     
         24 . The method of  claim 13  comprising positioning the preliminary composite on a shape-determining tool body for the plating and the forming. 
     
     
         25 . The method of  claim 24  wherein the shape-determining tool body is a round blank. 
     
     
         26 . A shaped part fabricated by a method comprising:
 providing a first layer comprising a first sheet metal material and a second layer comprising a second sheet metal material, wherein the first sheet metal material comprises an iron material with a carbon fraction of more than 0.1% by weight;   forming a preliminary composite that includes the first layer and the second layer;   plating the preliminary composite; and   forming the preliminary composite to obtain the shaped part by way of flow turning, compression, or deep drawing,   wherein plating the preliminary composite is performed before or during the forming of the preliminary composite to obtain the shaped part.   
     
     
         27 . The shaped part of  claim 26  wherein the carbon fraction in the iron material of the first sheet metal material is more than 0.25% by weight. 
     
     
         28 . The shaped part of  claim 26  wherein the carbon fraction in the iron material of the first sheet metal material is more than 0.5% by weight. 
     
     
         29 . The shaped part of  claim 26  configured as a joint head.
