Definitions

  • the locking means can be arranged in an eccentric, axially parallel recess in the journal bearing, preferably the bearing sleeve.
  • spring-supported detent ball and a number of detent recesses arranged circumferentially distributed over the end face of the scale carrier facing the relevant journal bearing can be formed in the radial spacing of the detent ball.
  • FIG. 2 shows a rear side view of the multiple punch in a partially broken diagram
  • a holder 58 is additionally formed on the lower part 10, which has a vertically oriented guide for a plunger 62 which bears against the pressure web 66 of the pressure lever 18 under the action of a support spring 60.
  • the spring-supported plunger 62 ensures that the pressure lever 18 is lifted in its upper end position from the rear ends 54 of the punch 56 held against its end stop 52 to form a free space 64 between the punch ends 54 and the pressure web 66.
  • the punching units are set free of pressure and can be easily adjusted in their mutual spacing within the lower part.
  • the structural unit consisting of square rod 34 and perforated units 20 can be removed with a handle from the lower part or inserted into it after loosening the set screw 42.
  • the scale carrier 24 has the shape of a round rod, on the ends of which axially projecting bearing journals 68, 70 are formed.
  • the round rod with the integrally formed bearing journals 68, 70 is expediently made of plastic by injection molding in the form of two longitudinally divided rod halves 25 (FIG. 4), which are locked together and / or glued together to complement the solid rod.
  • a plastic injection-molded part is placed on the longer journal 70 trained bearing sleeve 72 pushed on and secured at the end with a knob 74, which is attached to the bearing journal in a rotationally fixed manner, preferably glued, to prevent it from falling out.

Abstract

La présente invention concerne une perforatrice comportant un socle (10), au moins deux unités de perforation (20) à distance réglable, ainsi qu'un levier de pression (18) pivotant ou mobile sur le socle (10) pour assurer le déplacement des poinçons (56) disposés dans les unités de perforation (20). Pour pouvoir régler de manière simple et stable une pluralité d'écartements entre les perforations rencontrés habituellement dans la pratique, le socle contient un évidement (22) qui s'étend sur la longueur de fonctionnement de la perforatrice et dont le bord est ouvert vers le haut; cet évidement comporte un support de règle graduée (24) tournant autour de son axe longitudinal et présentant plusieurs échelles (24') visibles à travers l'ouverture du bord en différentes positions de rotation. Le porte-règle graduée (24) a la forme adéquate d'une barre ronde qui peut être verrouillée sur le socle (10) dans des positions de rotation prédéterminées.
