Definitions

  • the invention relates to a sleeve and a clamping tool for use in a system consisting of a clamping tool and at least one sleeve.
  • the sleeves are mounted by means of air pressure.
  • the carrier cylinders for the sleeves are relatively simple, while the sleeves themselves are complex. Examples are in the EP 0 865 933 A1 and in the EP 1 361 073 A2 shown.
  • the sleeves consist of several layers to allow mounting and clamping.
  • the EP 1 327 522 A1 discloses a tightening tool for use in a system of a tightening tool and at least one sleeve, comprising an inner body having a central axis and an outer body having a central axis coaxial with the central axis of the inner body, the inner body and the outer body being formed in the region of their faces to form Tie rods are firmly and pressure-tightly connected to each other and a means for applying the pointing to its central axis surface of the outer body with pressure is provided. Similar devices are also known from EP 1 004 455 A2 and from the EP 1 703 745 A1 known.
  • the clamping tool is characterized in that the outer body in the region between the tie rods has a material with a lower modulus of elasticity than that of the remaining material of the outer body.
  • the sleeve can be made entirely of a castable material.
  • the castable material may be an elastomeric or thermosetting plastic, in particular an epoxy resin, or else a metal or a metal alloy.
  • the castable material may be mixed with the modulus of elasticity and / or the stiffness and / or the conductivity-increasing and / or the weight-reducing fillers, in particular glass fibers, glass balloons, aramid fibers, carbon fiber, electrically conductive fibers and band-shaped materials.
  • the sleeves are thus produced in a casting process that can be carried out both in vacuum and under normal atmospheric pressure or overpressure.
  • the clamping tool takes into account the requirement that for high-quality printing and embossing applications a very homogeneous clamping of the sleeves on a carrier core or a tensioning shaft must be ensured.
  • Conventional segmented mechanical or hydraulic tensioning systems are detrimental to high quality printing because any undulations, pressure differences across the circumference or length of the tensioning means and differential strains on the surface of the tensioning means have a negative impact on the subsequent printing result.
  • An inventive clamping tool can be used for producing a sleeve.
  • FIG. 3 a clamping tool is shown, in which the part of the outer body 10 is formed with a high modulus of elasticity in the longitudinal direction with different wall thicknesses.
  • the wall has a higher wall thickness in its end regions A, C than in the middle region B.
  • the regions B with the smaller wall thickness then expand more strongly than the A, C with a greater wall thickness.
  • the variable thickness profile is not found on the surface, the surface in the unexpanded state, for example, be cylindrical or conical, without having a camber on the surface. This increases the useful tensioning travel and makes the machining of the lower modulus material of the coating 22 easier.
  • the result is a clamping tool that has a very homogeneous bending compensation and high bending stiffness and can transmit large forces.
  • FIG. 4 A method for the production of sleeves according to an embodiment of the invention is disclosed in FIG. 4 illustrated.
  • a manufacturing core is preferably used which has the features of the clamping tool according to the present invention.
  • the manufacturing core 100 is expanded to the desired inner dimension of the sleeve.
  • the manufacturing core 100 is enclosed with an outer mold 110 such that a cavity 120 between the manufacturing core 100th and outer shape 10 results.
  • This cavity 120 is then cast with pourable material, which is optionally mixed with fillers.
  • the castable material is cured, the sleeve 140 is completed.
  • the expansion of the manufacturing core 100 is canceled, as seen in panel (b), so that the sleeve 140 is ready for removal.
  • the outer jacket 110 can be removed or, according to a variant, which is shown in FIG. 6, at the same time form the outer tube of the sleeve. It can be provided, before the casting into the cavity 120 functional elements 150, such as identification chips to introduce.
  • FIG. 7 shows an air cylinder 200, as it is found, for example, in a modern flexographic printing press.
  • an adapter 210 is located on the air cylinder 200.
  • the adapter is expanded via a connection 218 with the aid of a fluid medium, for example hydraulically , and thus ensures by extension of the pressure chamber 216 for the necessary frictional engagement between the air cylinder 200 and the sleeve 220. If the clamping pressure is removed, so either the sleeve 220 and the adapter 210 can be deducted from the air cylinder 200.
