  • Patent number: 9346096
    Abstract: Tool-holder gripper for a multiple change of tools in a horizontal radial press having a set of jaws moving radially and axially, comprising a handle, a tool-holder disc, and angular centring devices acting in conjunction with a front flange of the press to angularly align the tools and jaws. The gripper is further provided with a radial, axial centring portion configured to abut against the front surface of at least one radial jaw when the tools and jaws are axially aligned but still disengaged, so that the subsequent axial advancement of the jaws is accompanied by a simultaneous axial reversing of the gripper.

  • Patent number: 7553268
    Abstract: The present invention relates to a tool holding clamp for a multiple change of tools for radial presses, where said presses comprise a plurality of radial jaws (12, 12?) onto which the tools (14) are mounted and where tools and jaws are provided with complementary coupling means, such as radial pins (15) and relative slots (16). The clamp presents centering devices, working together with the radial press to guarantee alignment of said complementary devices when the tools are mounted onto the jaws of the press. A tool holding rack for radial presses also constitutes the object of the invention, and is provided with devices adapted to interacting with the tool holding clamp for positioning the tools onto said clamp in the position of alignment with the jaws of the press.

  • Publication number: 20070252385
    Abstract: The present invention relates to a holding back device for a pressure hose to a joint. The device comprises an anchoring member, a band, a rope and an incision plate adapted for penetrating, once the hose his extracted, into the cover of the hose for holding back the hose once it disconnects from the joint. The band further comprises a metal ring and a rubber sheath, adapted for allowing the hose expansion during the normal system operation.
