Definitions

  • a first solution according to the invention consists in providing a band-shaped or plate-shaped semifinished product of a metallic material, punching out an annular blank from the semifinished product and then finishing it to form a piston top part, and the finished piston top part with a piston bottom part to form a piston is connected.
  • a second solution according to the invention consists of providing a band-shaped or plate-shaped semifinished product of a metallic material, finishing at least one surface of the band-shaped or plate-shaped semifinished product, punching out an annular piston upper part from the semifinished product and finally with a piston lower part is connected to a piston.
  • the present invention is characterized in that a particularly simple, feasible with a few manufacturing steps and thus cost-effective method for producing a piston is provided.
  • a piston upper part can be provided that is available in a particularly simple manner from any suitable material.
  • it is, for example, possible to provide a piston with a particularly resistant and temperature-resistant piston upper part in a simple and cost-effective manner.
  • a semi-finished product made of a steel material is used, so that the finished piston satisfies the requirements in the engine operation in an optimal manner.
  • a hot or cold rolled steel material is particularly well suited.
  • the finished upper piston part can be connected, for example, by welding or soldering with a piston lower part to a finished piston.
  • the piston can then be finished as needed.
  • Fig. 1 shows an embodiment of a piston according to the invention in section
  • Fig. 3 shows another embodiment of a according to the invention
  • annular blank 25 is punched out.
  • the blank 25 is machined along at least one surface, for example by grinding or turning.
  • this surface forms the piston bottom 11a of the piston upper part 11.
  • the finished piston upper part 11 is connected to a piston bottom part 15 to form a piston 10, for example by soldering or welding, such as friction welding, electrode welding or laser welding.
  • soldering or welding such as friction welding, electrode welding or laser welding.
  • the piston 10 may then be finished as needed.
  • the semi-finished product 22 can be further processed prior to punching by at least one of its surfaces 26 is machined plan, for example. By grinding or turning. Subsequently, an annular piston upper part 11 is punched out. The plane machined surface 26 forms the finished piston 10, the piston head 11 a of the piston upper part 11 forms. Subsequently, the finished upper piston part 11 is connected as described above with a piston lower part 15 to a piston 10.
  • FIG. 3 shows an exemplary embodiment of an annular piston upper part 111 punched out of a semifinished product 22.
  • the piston upper part 111 has a circumferential lower recess 127, which in the finished piston is part of a circumferential one Cooling channel forms, see. the cooling channel 21 in Figure 1.
  • the recess 127 is formed by the punching tool is provided in a conventional manner with a corresponding embossing mold. Thus, the recess 127 is formed simultaneously with the punching operation.
  • the central opening 113 of the annular piston upper part 111 forms part of a combustion bowl in the finished piston, cf. the combustion bowl 13 in FIG. 1. The same naturally also applies to the production of a blank from the semifinished product 22.
