Definitions

  • the invention relates to a tub or a washing drum of a washing machine with a jacket and at least one side wall of thin-walled sheet metal parts, which are partially provided with the strength-enhancing indentations, and also an embossing tool for producing a structural surface on the side wall.
  • a washing machine with a rotatably mounted in a tub drum is shown with a shell and two top surfaces, wherein the jacket is made of a metal sheet having a directed towards the drum interior arch structure of polygons.
  • the top surfaces may be provided with curved polygons.
  • the invention has the object of providing a tub and / or a washing drum of a washing machine of thin-walled sheet metal parts in such a way that he / she has sufficient rigidity in itself.
  • the invention is also based on the further object of providing a particularly simple embossing tool for the production of a structural surface on a device part consisting of thin-walled sheet metal.
  • a flat, finely divided structure 5 impressed can also be provided on the other side wall of the tub 1.
  • a honeycomb-shaped structure surface 8 is embossed in the material of the side walls 7.
  • the individual honeycomb of this structure surface 8 are arranged and executed in their radially zuenden size so that the existing between the individual, embossed as recesses honeycomb raised webs 11 on its extension between the radially inner and the radially outer boundary line 9 and 10 of the honeycomb Structure surface 8 have one of the likewise radially extending between the radially inner and the radially outer boundary line 9 and 10 extending straight radial lines 12 course.
  • the connecting paths formed by the webs 11 between the boundary lines 9 and 10 have a soft spring characteristic which effects a good noise damping.
  • the embossing of the structure 5 or the structural surface 8 takes place by means of an embossing tool shown schematically in FIG. 3.
  • This stamping tool has two jaws 13 and 14. On one jaw 13, a die 15 corresponding to the structure 5 or the structural surface 8 is attached. The other jaw 14 is smooth in the region 15 opposite the female mold 15. On the smooth surface of an elastically deformable material (eg, a known under the brand name Vulkollan ® polyurethane elastomer) existing coating 17 is applied.
  • an elastically deformable material eg, a known under the brand name Vulkollan ® polyurethane elastomer
  • the material of the side walls 4 and 7 is pressed by the die 15 against the pad 17.
  • the material of the lining 17 is compressed more strongly at the points where the die 15 has elevations 18.
  • the lining 17 presses corresponding recesses (for example honeycombs) into the material of the respective side wall 4 or 7
  • Use of the elastically deformable lining 17 makes it unnecessary to have a separate die formed as a counter-die to the die 15.
