Definitions

  • the present invention relates to a radial press with a housing, an annular guide body arranged around the press axis and an outer pressure ring surrounding the guide body and rotatably mounted about the press axis, the guide body having a plurality of openings in which slides are guided in a radially displaceable manner , which are coupled to the pressure ring via its rotation in radial movements converting gear.
  • a radial press of the type mentioned above is known from DE 3331721 C2.
  • Each of the sliders is connected to the pressure ring via a link, each link being articulated on both the slide and the pressure ring. This results in a toggle-type gear arrangement between the pressure ring and the slides.
  • the known radial press of the generic type has not proven itself in practice.
  • the decisive factor here is that the handlebar arrangements - with practical dimensions of the radial press - are not suitable for transmitting the high pressing forces required in modern radial presses. Because, if the press stroke is to meet the usual requirements, they must be of relatively slim design due to their construction, so as not to impede the opening of the radial press.

  • each of the slides is assigned a wedge bevel arranged on a radial inner surface of the pressure ring
  • "wedge bevel” in the sense of the present invention means that the surface in question is not arranged on a circular path concentric to the press axis, but rather that the surface the "wedge bevel” increasingly approaches the press axis over a certain angle of rotation. If the pressure ring is rotated, the slides are moved synchronously radially inwards via the associated wedge gears, the wedge bevels of the pressure ring sliding on the slides.
  • the wedge bevels are designed as circular arc segments arranged eccentrically to the press axis.
  • the slides particularly preferably each comprise a base body and a pressure piece bearing on the associated wedge slope of the pressure ring, the contour of the pressure pieces being limited by two circular arc segments, one of which is flat on the associated wedge slope of the pressure ring and the other the other lies flat against a concave counter surface of the associated base body.
  • the pressure piece can be rotated within the shell-like counter surface of the associated base body of the slide. This enables the pressure piece to lie flat against the associated wedge slope of the pressure ring during the entire pressing process. Since the pressure piece lies flat against both the wedge bevel of the pressure ring and the base body of the slide, the corresponding dddd CQ 1
  • the drive devices are particularly preferably designed as linear drives with mutually parallel directions of action. This, in turn, is favorable with regard to driving the pressure ring free of transverse forces.
  • the linear drives are connected to the pressure ring via tension bands which rest on guide surfaces of the pressure ring.
  • each linear drive can be connected to the pressure ring via two tension bands in the form of a rope loop, the pressure ring each having a groove extending in the circumferential direction between the two associated guide surfaces.
  • the guide surfaces are particularly preferably designed in the form of circular arc segments whose center of curvature lies on the axis of rotation of the pressure ring, the linear drives being rigidly connected to the housing.
  • the pressure ring is constructed from two ring disks and a number of wedge pieces corresponding to the number of slides, which are arranged between the two ring disks. This enables cost-effective production of the pressure ring with high precision of the geometry of the wedge bevels.
  • any other suitable structure of the pressure ring is also considered, for example its manufacture as a gray cast iron part, which is machined only on the force application surfaces.
  • a number of press jaws corresponding to twice the number of slides is provided.
  • a press jaw is mounted in a stationary manner in each slide, and the other press jaws are each slidably supported on two adjacent slides on guide surfaces.
  • the number of slides is (only) half as large as the number of press jaws, this enables the slides to be dimensioned accordingly, which proves to be favorable in the sense of a robust design of the radial press according to the invention.
  • the arrangement of the guide surfaces results directly from the number of slides or press jaws. If four slides are provided for eight press jaws, the two guide surfaces of each slider form an angle of 135 ° with one another.
  • Press jaw is assembled from a base jaw and a press head attached to this.
  • FIG. 1 is a perspective view of a first embodiment of a radial press according to the present invention
  • Fig. 2 is a perspective view of a modification of the tool used in the radial press of FIG. 1 and
  • FIGS. 1 and 2 shows a press jaw set used in the tool for use in the radial presses according to FIGS. 1 and 2.
  • the housing 1 comprises a housing 1, which is essentially composed of two plates 2 and two panels 3. Only the two plates 2 are essential for the power transmission.
  • the linings 3 can thus be produced inexpensively and easily, for example by manufacturing them from a thin-walled sheet metal.
  • a guide body 4 is fixedly connected to the housing 1. This is formed by four segments 5, which are firmly connected to the two plates 2 of the housing and keep them at a distance. Each two adjacent segments 5 define an opening 6 between them, in each of which a slide 7 is radially displaceable (double arrow A). Each slide consists of a base body 8 and a pressure piece 9. The pressure pieces 9 each lie on one
  • the two drawstrings 22 of each rope loop 20 are in this way in their free areas not lying on the guide surfaces 23 of the pressure ring 11 in the same plane as the piston rod 18 of the associated plunger 17, the two corresponding planes assigned to the two plungers 17 relative to one another run in parallel.
  • a reset element 25 in the form of a double-acting hydraulic cylinder 26 is provided for opening the press. This acts between the cylinder of one of the plungers 17 on the one hand and the pressure ring 11 on the other.
  • the hydraulic cylinder 26 could directly engage the housing 1, for example one of the plates 2, or another component fixed to the housing.
  • the hydraulic cylinder 26 also serves as a rapid drive for rapid closing of the press until shortly before the start of the force pressing via the linear drives 16.

Abstract

Presse radiale qui comporte un boîtier (1), un corps de guidage (4) annulaire placé autour de l'axe (12) de presse et une bague de pression (11) externe entourant le corps de guidage (4) et montée rotative autour de l'axe (12) de presse. Le corps de guidage (4) comporte une pluralité de passages (6) dans lesquels sont guidés des coulisseaux (7) à coulissement radial couplés avec la bague de pression (11) par l'intermédiaire d'éléments de transmission qui convertissent la rotation (B) de la bague de pression en mouvements radiaux (A). Lesdits éléments de transmission se présentent sous forme de coins du fait que la bague de pression (11) possède sur sa surface interne radiale un nombre de faces inclinées (13) correspondant au nombre des coulisseaux (7).
