Definitions

  • the invention relates to a method for improving the accuracy of stanzp elected laminated cores, in particular of stanzp elected electrical steel cores.
  • the punching package of sheets is a example of the EP0133858 A1 Known method for producing laminated cores in a single operation.
  • the individual sheets cut out in a known progressive tool are stacked on top of one another and joined together by an integrated method described in more detail below in the tool.
  • slugs are punched by an embossing process, leaving a slug hole in the form of a blind hole in the single sheet. In this hole, the slugs of the individual sheet produced in the next punching are pressed during the cutting process.
  • the strength of the resulting composite sheet is dependent on the clamping force with which the slugs sit in the Butzenlöchern, which in turn depends on the dimensions of slugs and Butzenlöchern. These dimensions must be in close tolerances and their temporal consistency depends on various factors such as tool wear and tolerances in the material properties of the sheets. In addition, the slugs must be manufactured and joined with sufficient positioning accuracy with respect to the slug holes. If the rigorous Gebung from Butzen to Butzenloch too low, the composite sheet can separate again.
  • the invention is therefore an object of the invention to improve the process of Stanzbierens such that the committee or the required rework is minimized by mutually releasing sheets and non-plane-parallel laminated cores.
  • the slugs can be pre-embossed for better dimensional stability, the slug holes are pre-punched accordingly.
  • Fig. 1 is an advantageous embodiment of a located in a first side of a single sheet Butzenlochs (10) with three distributed over the outer circumference, in the otherwise circular cross-section of the Butzenlochs protruding lugs (11) to see.
  • a circular slug (15) can be seen on the opposite second side of the single sheet.
  • Fig. 2 is a section of a Butzen- or Butzenlochgargestation a follow-on composite tool for producing inventive single sheets with a recess (53) for forming a nose (11) providing embossing punch (50), a hold-down (55) and a male (56) to see ,
  • the single sheet (1) lies above the bore (57) in the male part (56).
  • the pressure of the descending stamping die (50) of the slug (15) and the slug hole (10) is embossed.
  • the diameter of the bore (57) and thus the outer diameter of the slugs (15) is greater than the pitch circle diameter (54) of the lugs, but smaller than the foot diameter (12) of the Butzenlochs (10).
  • the slugs (15) clamp on the lugs (11), which they plastically deform when pressed in the nerierstation the follow-on composite tool (not shown).
  • the noses (11) can thereby flow into the gap, which results from the difference between the outer diameter of the Butzens and the base diameter (12) of the Butzenlochs (10).
  • Fig. 3 schematically shows a laminated core, which consists of the stamping of the slugs (15) in the corresponding slug holes (10) interconnected individual sheets.
  • Fig. 4 shows a section of a single sheet with embossed Butzenloch (10) and three evenly distributed over the hole circumference lugs (11) in plan view. Evident are the foot diameter (12) and pitch circle diameter (54).
  • Fig. 5 is the corresponding die (50) of the follow-on composite tool with recesses (53) to see the formation of the noses.
  • the invention is not limited to the embodiment with lugs (11) in the slotted hole (10).
  • lugs (11) in the slotted hole (10).
  • a Dahlberggeometrie in Butzenloch denkar instead of the noses a Dahlberggeometrie in Butzenloch denkar. It is also conceivable to attach the toothing on the outer diameter of the Butzens 15 and to equip the Butzenloch circular or also with a tooth geometry.
