Definitions

  • the contour of the respective engagement surfaces does not necessarily have to be designed such that a thread is produced. Rather, the tool elements can be provided with a different (even non-uniform) shape instead of a thread, so that any internal or external contours can be created. If required, these contours can result in a closed circle (360 °).
  • the tool according to the invention for the non-cutting production of internal contours on workpiece recesses with a free cross-section or for carrying out cutting work of such workpieces from the inside to the outside has a plurality of tool elements which are arranged in the basic state such that they are recessed of the workpiece are insertable.
  • a spreader element brings the tool elements into a state of engagement by movement substantially perpendicular to the surface of the workpiece, in which the workpiece elements are pressed against the workpiece walls in such a way that they form the desired contour or perform cutting, notching or perforating work.
  • the number of tool elements is predetermined by the respective cross section of the workpiece.
  • the number of sides or corners of the polygon corresponds to the number of required leading and trailing tool elements. For example, if the workpiece has a rectangular profile, four leading and four lagging tool elements are required.
  • FIG. 6 shows an exemplary embodiment in which a sealing surface can be produced by a corresponding design of the tool elements in the area of the thread.
  • a sealing surface is to be provided if a closure means with a sealing function is to be introduced into the thread to be produced.
  • This sealing surface can be produced both in the case of external and internal threads by the tool elements and / or additional shape-supporting or shape-producing auxiliary elements 7. If undercuts are created when creating the sealing surface, separable counterholders 5 must be used.
  • Spring resets 4 can in particular be used as the resetting mechanism for tool elements. Feathers in various forms, e.g.

Abstract

Instrument pour la réalisation de profils extérieurs ou intérieurs sans enlèvement de copeaux sur des pièces à usiner et notamment pour la réalisation de filets extérieurs ou intérieurs. Cet instrument comporte plusieurs éléments (1) qui se trouvent disposés dans un état initial tel qu'ils puissent être introduits dans la pièce à usiner. De plus, un élément d'écartement (3) est prévu, qui amène les éléments (1) en position de contact, par un mouvement essentiellement perpendiculaire à la surface supérieure ou dans le sens radial. Les éléments (1) sont alors pressés contre la pièce à usiner (6) de sorte à façonner le profil voulu sans qu'il y ait un espace libre séparant lesdits éléments.
