Definitions

  • the object of the invention is to produce these inner cylindrical surfaces with high precision and in a simple, cost-saving manner.
  • the aim is to produce a high-precision, large, bowl-shaped surface that has a reproducibility that is closely tolerated in the manufacturing process.
  • Fig. 2 shows a longitudinal cross section through the molding tool
  • FIG. 3 shows a detail from FIG. 2.
  • a molding tool (1) is shown in section, with the aid of which the required high-precision surface is to be molded in a component (2), also shown as a sectional image.
  • the required high-precision surface (3) is molded on an outer cylinder.
  • the impression cylinder used is with the desired one Precision manufactured.
  • the component (2) is the bed of an inner drum imagesetter, which already has the rough geometry of the required area and which, among other things, is to have a high-precision inner cylindrical surface for receiving the film material.
  • the component (2) is positioned with respect to the molding tool (1) so that the position of the outer surface (3) of the molding tool (1) is in the desired later position.
  • the surface (3) to be molded must meet the requirements with regard to the desired accuracy and surface quality.
  • component (2) and impression tool (1) is shown in the side view in FIG.
  • another high-precision surface (5) is molded, which will later be used to hold another component. If necessary, other high-precision surfaces that are in close tolerance to each other can of course be molded, which will later be used to hold additional components.
  • the tool (1) and the component (2) must then be prepared accordingly.
  • the molded outer surface (3) later serves as a contact surface (3) for materials to be exposed.
  • the gap between the impression tool (1) and the workpiece (2) is filled with an impression compound (4).
  • FIG. 3 shows a detail A from FIG. 2, in which it is shown that the application of structures is also possible in the high-precision surface (3).
  • structures that serve as air channels (6) for the subsequent application of vacuum for sucking the film into the surface (3) can also be molded at the same time.
  • Such structures can advantageously be produced in such a way that a negative of the structure is applied to the surface of the molding tool, either by gluing on corresponding negative structures or, in the event that large structures are desired, by gluing on corresponding negative foils.
  • the impression material (4) After the impression material (4) has been introduced, it can harden and after the hardening, the impression tool is removed. It may be necessary to remove excess molding compound from the edges, which is done by plastering the impression surfaces. After the curing process, an area is obtained which corresponds to the quality of the outer cylindrical shape of the molding tool. It is also within the scope of the invention to mold the required area directly on an outer cylindrical shape, which has the shape of the impression tool (1), for example. In this case, carbon fibers or glass fibers which are impregnated with liquid epoxy resin can advantageously be wound onto the molding tool (1) at certain angles. After curing, a cylindrical tube is formed, which is separated into two halves, whereby two usable half-shells, each with a highly precise contact surface (3), are created. To ensure that the cylinder contour is not deformed when it is cut open, a layer structure made of carbon or glass fibers and honeycomb material that is matched to the dimensions must be provided.

Abstract

L'invention concerne un procédé de production de surfaces d'appui de haute précision pour matériaux à exposer à la lumière en technique de reproduction. Selon ce procédé, on produit un outil de moulage (1) ayant une surface d'appui (3) appropriée pour le matériau à exposer à la lumière. Une pièce (2) destinée à maintenir la surface d'appui de haute précision est préfabriquée de manière à ce qu'elle puisse recevoir l'outil de moulage avec une fente d'air entre ladite pièce et l'outil de moulage. La pièce et l'outil de moulage sont positionnés l'un par rapport à l'autre, la fente d'air étant maintenue, de manière à ce que la position ultérieure de la surface extérieure de l'outil de moulage soit déterminée par rapport à la pièce préfabriquée. La fente d'air est remplie de matière de moulage (4). Après durcissement de la matière de moulage, l'outil de moulage est enlevé.
