Definitions

  • the invention relates to a forming machine, in particular a mechanical press, with two machine parts which can be moved in a straight line relative to one another, the one machine part being guided on planar guide surfaces of the other machine part with planar guide surfaces running parallel and perpendicular to one another on counter guide surfaces having counter guide surfaces.
  • the mechanical presses can be toggle, articulated, crank or eccentric presses _ with under drive or top drive _.
  • the machine parts are then the press frame and the press housing or the ram and the stand.
  • each guide surface In a known forming machine of the type mentioned (US-A-3 568 498, Fig. 1, 2), only a single counter-guide element is assigned to each guide surface.
  • Each of these counter-guiding elements consists of a plate abutting the associated guide surface, which has a ball socket recess on its back, in which a spherical cap part which is adjustable perpendicular to the direction of movement of the machine parts lies. With these configurations, eccentric force attacks should be better absorbed. Since only one countermeasure organ is provided for each guide surface, these countermeasure organs must be proportionate be large.
  • the execution of the counter-guide elements as plates with a ball socket recess on the back is also complex since the counter-guide elements are wearing parts.
  • the invention has for its object to develop a forming machine of the type mentioned so that the manufacture of the guide is simplified and a simpler adaptation of the associated guide members is possible.
  • each guide surface is assigned at least two counter-guide elements which are arranged with each other in the direction of movement, and that each counter-guide element is designed as a spherical cap made of a lubricious material, with its flat spherical surface on the associated guide surface and with its spherical spherical surface a corresponding spherical segment surface of a ball socket body which is adjustable approximately perpendicular to the direction of movement in the associated machine part.
  • the invention is based on the finding that when two counter-guide elements are arranged one above the other per guide surface, the counter-guide elements can be so small that the overall technical effort is less despite the doubling.
  • the production of the wearing counter-guiding elements as spherical caps is much easier and cheaper than the embodiment as a plate with a ball socket recess on the rear.
  • it is to be regarded as advantageous that the guide surfaces and flat surfaces of the spherical caps Due to the pivotability of the spherical caps in the ball socket bodies, which is possible in all directions, it can be automatically adjusted under all circumstances and hydrodynamic lubrication ensured. Manual rework is not necessary during production.
  • the counter-guide elements are arranged parallel to the two guide levels, there is no longer any mutual interference by force components.
  • the individual countermeasures can be delivered independently of one another and depending on the respective local conditions and requirements.
  • the spherical caps can be replaced quickly and easily from the outside if they wear out, without the need for time-consuming machine disassembly.
  • the elements can be arranged in a frame guide so that the frame deformations caused by loading lead to a reduction in play and thus to a more precise guidance.
  • the mechanical presses shown in the figures have two machine parts 1, 2 which can be moved in a straight line relative to one another (press frame and press housing or ram and stand).
  • One machine part 1 is in Direction of movement 3 extending guide surfaces 4, 4 'guided on counter-guide elements 5 of the other machine part 2.
  • the counter-guide elements 5 are ale spherical caps 6 made of a slidable material, with their flat spherical surface 7 on the associated guide surface 4, 4 'and with their spherical spherical surface 8 each on a corresponding spherical segment surface 9 of a ball socket body which is adjustable perpendicular to the direction of movement 3 in the associated machine part 2 10 concerns.
  • the spherical caps 6 consist of bronze or plastic or bronze and a plastic insert which has the flat spherical surface 7.
  • the ball socket body 10 is screwed into the associated machine part 2 with an external thread and is braced against this machine part 2 by means of a rear threaded shaft 11.
  • Each guide surface 4, 4 ' are assigned at least two, generally four, counter-guide elements 5 located at the corners of a rectangle.
  • four of these counter-guide elements 5 are assigned to the outer guide surfaces 4, which are parallel to the frame plane.
  • the frame 1 perpendicular to these guide surfaces 4 lying inner and outer guide surfaces 4 '. The arrangement is such that the frame 1 'is guided with its inner guide surfaces 4' only on upper pairs of counter-guide members 5 and with its opposite outer guide surfaces 4 'only on lower pairs of counter-guide members 5.
  • each guide surface 4, 4 'four, at the corners of a rectangle lying guide elements 5 are assigned.
