Description

collerette ou butée du petit tube porte-bille. 0" dernier est

lui de la pointe finie. les déchets de fabrication ayant une valeur presque nulle; en outre les opérations de décolletage et autres dorment lieu à une dépense en main d'oeuvre importante et le tout conduit à un prix de revient très élevés
L'invention a pour objet un procédé suivant lequel la pointe est obtenue de préférence par refoulage d'un petit tube
<EMI ID=5.1>
ensuite sertie lâche sur oe siège.
La. partie réduite en diamètre par un outil à tréfiler
<EMI ID=6.1> <EMI ID=7.1> la figure 8 montre, en coupe partielle, la pointe aise en place au bout du tube contenant la réserve d'encre.
Suivant l'invention, on part d'un petit tube métalli-
<EMI ID=8.1>
bout pour refouler le métal qui commence à gonfler dans sa partie découverte (figure 2) et s'écrase en formant la collerette^
<EMI ID=9.1>
par forage d'une pièce massive.
Par usinage mécanique on alèae ensuite la partie rétré-

L'opération par laquelle on torse la partie oyltndri-

collar or stopper of the small ball-holder tube. 0 "last is
<EMI ID = 3.1>
<EMI ID = 4.1>
him of the finished point. manufacturing wastes of almost zero value; in addition, bar turning and other operations result in a significant expenditure of labor and the whole leads to a very high cost price
The invention relates to a method according to which the tip is preferably obtained by upsetting a small tube
<EMI ID = 5.1>
then crimped loosely on this seat.
The part reduced in diameter by a drawing tool
<EMI ID = 6.1> <EMI ID = 7.1> FIG. 8 shows, in partial section, the tip easily in place at the end of the tube containing the ink reserve.
According to the invention, one starts with a small metal tube
<EMI ID = 8.1>
end to push back the metal which begins to swell in its uncovered part (figure 2) and crushes, forming the collar ^
<EMI ID = 9.1>
by drilling a solid piece.
By mechanical machining is then alèae the retracted part

ink passage.
The operation by which we twist the part oyltndri-

Other details of the process, in general, may vary within wide limits to suit the requirements.
