Description

  

  Punaise et procédé pour sa fabrication.    L'objet de la. présente invention est un       procédé    pour la, fabrication de     punaises,    par       emboutissage    de plaques faisant saillir la  pointe d'un point quelconque de la plaque, la       punaise    réalisée selon     @ce    procédé étant     ,ainsi     obtenue de façon que le métal qui la     co:nsti-          tue.    reste en une seule pièce et sans solution  de :continuité.  



  Le dessin annexé montre, à titre     d'exem-          ple,    une forme d'exécution     de    l'objet de l'in  vention.  



  La     fib.    1 est une coupe axiale de la,     pla-          que        destinée    à être emboutie;  La,     fig.    2 est une :coupe axiale de la pu  nel.ise finie:  La.     fig..    3 est une vue en plan depuis le  haut :correspondant à. la.     fib.    2.  



  La, plaque 1, circulaire et de diamètre D',  (St     soumise    à. la poussée -d'un -doigt     d'embou-          i        issa.be,    non représenté, qui pousse partielle  ment le métal de 1 dans une forme     d'emb:ou-          t:

  is.@a.be.    Cette poussée fait saillir du métal  de la, plaque la. pointe 2 pourvue au milieu    d'un     évidement    3 dû à l'introduction du doigt       d'emboutissage.    Le métal qui -constitue la  pointe     2)    étant emprunté à la. plaque originale  1, le diamètre extérieur de celle-ci diminue de  <I>D' à D".</I> L'emboutissage laisse subsister un  congé 4 reliant la face 5 de la plaque avec       l'extérieur    de la pointe 2 et un congé 6     re-          li.a.nt    la face 7 de la plaque avec     l'évidement     intérieur 3 de la pointe 2.



  Pushpin and method for its manufacture. The object of the. present invention is a process for the manufacture of tacks by stamping plates projecting the tip from any point of the plate, the pin produced according to this process being, thus obtained so that the metal which co: nsti -          kill. remains in one piece and without solution of: continuity.



  The accompanying drawing shows, by way of example, an embodiment of the object of the invention.



  The fib. 1 is an axial section of the plate intended to be stamped; The, fig. 2 is an: axial section of the finished pu nel.ise: Fig. 3 is a top plan view: corresponding to. the. fib. 2.



  The, plate 1, circular and of diameter D ', (St subjected to. The thrust -of a -digt d'embou- iissa.be, not shown, which partially pushes the metal of 1 into a form of emb: or- t:

  is. @ a.be. This thrust protrudes from the metal of the plate. tip 2 provided in the middle with a recess 3 due to the introduction of the stamping finger. The metal which -constitutes the point 2) being borrowed from the. original plate 1, the outside diameter of the latter decreases from <I> D 'to D ". </I> The stamping leaves a fillet 4 connecting the face 5 of the plate with the outside of the tip 2 and a fillet 6 connects the face 7 of the plate with the interior recess 3 of the tip 2.
