Definitions

  • the invention relates to a machine for producing Can bodies, especially of frames for molded cans, with one Rotary body with several stations, each, especially provided with a spreading tool at least one of one with a control curve in the Engaged cam roller can be actuated Tool part is assigned that is parallel to Rotation axis of the rotating body guided and provided for the application of an axial compressive force is.
  • a spreading tool is known from US Pat. No. 5,022,254. where one instead of an elastic stamp several segments distributed over the circumference are used, with the spreading segments - on an axial movement hindered - by an axially moving conical mandrel be moved radially outward.
  • cam-controlled drives The main disadvantage of cam-controlled drives is that the cam roller has significant forces must record or transfer, these forces with increasing output (can frames / time unit) or corresponding speed and thereby increasing Mass forces are also increasing. Correspondingly high the wear of the components.
  • the invention is therefore based on the object Device of the type mentioned at the beginning improve that the susceptibility to wear of the components even with large output reduced and their Life span will extend accordingly.
  • the cam roller with the central joint one Knee joint is connected, being from the outer Joint points of the knee joint connection a joint point with the one intended to transmit a compressive force Tool part and the other pivot point with the Rotational body is connected.
  • the intended tool parts are those on the cam roller forces acting or to be transmitted by it same load on the tool part is significantly reduced. In this sense, the fact that due to the geometry of the knee joint itself on End of the stroke or at the end of the molding process single can frame if a large force of that Applying the tool part is only proportional absorbing or closing low force from the cam roller is transferred.
  • a very space-saving and yet effective Embodiment arises when the cam roller directly on one of the levers or handlebars Knee joint connection, especially on the rotating body articulated lever, is mounted.
  • the drive 10 for a molding machine has one Rotating body 11, which is about a vertical axis 12 is rotatably mounted and driven.
  • the rotating body 11 has evenly distributed on the circumference, each guides 13, 14 arranged one below the other, in which Quill 15 slidable parallel to the axis of rotation 12 are performed, which are used to operate tools, eg. B. serve to spread the segments of spreading tools.
  • Spreading tools are e.g. B. in U.S. Patent 5,022,254 described, the central conical disclosed there Inner shaft instead of at the end of a piston rod on the upper end of the quill 15 is to be thought.
  • a double handlebar or a double joint bracket 16 (on each side of the quill 15 is a handlebar or one Articulated strap arranged) articulated via a bolt 17.
  • the head 18 At the free end of the double hinge bracket 16 is between the two individual tabs the head 18 one more fork-shaped handlebar or lever 19 on a common Bolt 20 hinged.
  • the forked end 21 of the lever 19 is articulated on a bolt 22, which on a Bearing holder 23 is attached.
  • the axis of the pin 22 extends tangentially with respect to the axis of rotation 12 and is the same distance from it as that Longitudinal central axis 15 'of the quill 15.
  • the bearing holder 23 is firmly connected to the rotating body 11.
  • Fig. 1 shows the drive in the lower end position of the Quill 15, while in Fig. 2 its upper end position is shown.
