Definitions

  • the invention relates to a holding device for printing forms designed as hollow cylinders in mold production, in particular in the electroplating sector.
  • Hollow cylinder printing forms are mainly used in packaging printing.
  • the tightness must also be guaranteed. ie there must be no electrolyte in the interior of the hollow cylinder printing form reach.
  • hollow cylinder printing forms have been held mainly by chucks which clamp the hollow cylinders by means of hydraulics on the end faces (JP-59-16 753, JP-61-26 37 54).
  • the hollow cylinders are provided with conical bores on the end faces.
  • an annular seal presses against the cylinder end wall and thus seals the gap between the holding device and the hollow cylinder.
  • the invention has for its object to provide a spatially small, technically inexpensive holding device for hollow cylinders of the type mentioned and for the purpose explained.
  • a holding device for hollow cylinder printing plates according to the preamble of claim 1 is characterized according to the invention by a ratchet device attached to each end of the adapter ring facing the hollow cylinder inside with a plurality of star-shaped, spring-loaded pawls, which, when the adapter ring is pressed into the respective hollow cylinder end, the inside end face of a insert the respective end of the hollow cylinder end, which is firmly connected to the inner wall of the hollow cylinder, and secure the adapter ring against falling out.
  • the small adapter pieces which are inserted on both ends into the conical bore of the discs fixed to the inside of the cylinder, are clamped by the pawl mechanism. This prevents the adapters from falling out again after being pressed into the conical round bore.
  • the outside of the adapter rings attached flange shoulders with a seal pressing against the cylinder face ensure a certain additional axial bracing, but also a secure seal against the penetration of electrolyte into the hollow cylinder interior.
  • the adapter parts according to the invention offer additional advantages in connection with a correspondingly adapted crane transport system when handling the hollow cylinder printing plates in a galvanic system.
  • the hollow cylinders can be safely transported by means of a crane traverse, which grips the hollow cylinder with a form fit.
  • the necessary current and torque for rotating the hollow cylinders in the electroplating system can be ensured by means of quills in the electroplating system within axially displaceable sealing tubes which prevent the penetration of electrolyte.
  • FIG. 1 shows an end face of a hollow cylinder printing form 1 (hereinafter referred to only as a hollow cylinder), into which a ring, called a round blank 2, with a conical inner bore is inserted.
  • Essential for the holding device according to the invention is an adapter ring 4, which is pressed into the axial bore of the round blank 2 and, as can be seen in FIG. 2 (left), engages with the conical inner bore of the round blank 2 due to a conical axial approach reached.
  • the adapter ring 4 is connected on the side facing the interior of the hollow cylinder 1 to a retaining ring 9, the diameter of which is slightly smaller than the inside end diameter of the round blank 2.
  • the retaining ring 9 is offset from one another by 120 ° in the example 3 shown
  • the hollow cylinder 1 can be lifted by means of a crane traverse 10 with axially displaceable positive and non-positive clamping jaws 11 in order to transfer the electroplating system shown schematically in FIG become.
  • sealing tubes 13 held by sleeves 12 are attached before the actual machining.
  • the sleeves 12 engage in a correspondingly adapted axial bore 4b of the adapter ring 4, so that reliable guidance, transmission of current and torque is ensured with a complete seal at the same time.
  • the spring-loaded pawl mechanism with the pawl 5 can be released by inserting the pin into the bore 14 by means of a pin, not shown, so that the adapter rings 4 can be removed for another, different use.

Claims (3)

  1. Dispositif de support de formes d'impression en forme de cylindres creux (1), pour la réalisation de formes, en particulier dans le domaine galvanoplastique, les extrémités frontales du cylindre creux (1) présentant chacune un alésage axial conique et une bague d'adaptation (4) qui est insérée dans ledit alésage axial conique et munie extérieurement d'un épaulement de bride (8) circulaire avec une bague d'étanchéité (7) appliquée contre la paroi frontale du cylindre, caractérisé en ce qu'il comporte un dispositif d'encliquetage rapporté à l'extrémité respective de la bague d'adaptation (4) tournée vers l'intérieur du cylindre creux, avec plusieurs cliquets (5, 6) disposés en étoile et commandés par ressort qui, lorsque la bague d'adaptation (4) est enfoncée dans l'extrémité respective du cylindre creux, passent derrière la surface frontale intérieure d'un flan circulaire (2) inséré dans l'extrémité considérée du cylindre creux, située du côté frontal, et solidaire de la paroi intérieure du cylindre creux.
  2. Dispositif de support selon la revendication 1, caractérisé en ce que la bague d'adaptation (4) présente un alésage axial par l'intermédiaire duquel les cliquets (5) peuvent être déplacés, au moyen d'une tige, contre la précontrainte respective du ressort, pour débloquer le serrage.
  3. Dispositif de support selon les revendications 1 ou 2, caractérisé en ce qu'il comprend trois cliquets (5) montés de manière pivotante et respectivement à une distance angulaire de 120°, dans une bague de fixation (9) couplée avec la bague d'adaptation (4).
