Definitions

  • the jet shape compressed air line 38 is connected to the outlet of the cleaning unit 56 via a second pressure regulator 62 and a further 2/2 solenoid valve 64.
  • the output of the cleaning unit 56 is finally connected via a further pressure regulator 66 to a compressed air motor 68 which works on a diaphragm pump 70.
  • the control part 82 can count the pressing cycles on the basis of the output signal of the displacement sensor 46. If desired, only every second, third, etc. sheet of metal can be sprayed with lubricant if the deformation of the sheet of metal is only slight, so that the lubricant left by a previous sheet of metal in the mold for one, two or more subsequent ones Sheet metal is sufficient.
  • the output of the A / D converter 170 is additionally connected to a digital differentiating circuit 180.
  • the table speed signal thus obtained is converted into the lead signal in a computing circuit 182, the computing circuit 182 receiving a further signal via a line 184 which corresponds to the velocity of the droplets in the droplet cone.
  • This further signal can e.g. be derived from the output signal of a pressure sensor (not shown) which is pressurized with the pressure of the atomizing air.

Abstract

L'invention concerne une tête de pulvérisation (28) qui produit un brouillard de gouttelettes conique. Ladite tête de pulvérisation (28) est pourvue de deux canaux d'air de formage (156) diamétralement opposés situés à proximité de l'orifice de sortie du brouillard. Les jets d'air de formage sortant de ces canaux aplatissent le brouillard de gouttelettes de telle manière que ce cône de brouillard présente un grand angle d'ouverture dans une direction et un petit angle d'ouverture dans l'autre direction. Un tel brouillard aplati permet de recouvrir des surfaces partielles d'une pièce à usiner avec une couche de liquide en épousant particulièrement bien les contours.
