Definitions

  • the present invention relates to a radial press with two press yokes and a plurality of press jaws, the press yokes being arranged in a plane perpendicular to the press axis, diametrically opposed to one another with respect to the press axis and being able to be moved in a straight line by means of a drive unit in a direction of movement transverse to the press axis , and wherein at least some of the press jaws mounted in the press yokes have sliding surfaces, each of which cooperates with a control surface of a press yoke or an adjacent press jaw in such a way that when the two press yokes approach each other, all press jaws are moved uniformly towards the press axis.
  • the task on which the present invention is based is derived from this, which consists in creating a radial press of the type mentioned at the outset which can be implemented as a table-top device, possibly even as a tool of an industrial robot.
  • the drive unit comprises at least one cross slide assigned to a press yoke and displaceable relative to one another transversely to the direction of movement of the press yokes, the movement of which is converted into a movement of the assigned press yoke via a deflection device.
  • the radial press according to the invention is thus characterized by an indirect drive of at least one of the two press yokes, in that the movement of at least one cross slide, which can be displaced relative to one another transversely to the direction of movement of the press yokes, is converted into a movement of the press yoke in question via a deflection device, for example, implemented as a wedge gear.
  • the drive unit enables an extremely compact structure of the radial press, which can be designed as a table-top unit due to its small size, which cannot be achieved with the conventional structure.
  • the invention thus provides for the first time a compact radial press with a flat tool - in the direction of the press axis.
  • the construction of the radial press according to the invention enables various particularly preferred developments, which, as will be explained below, have very considerable practical advantages over the prior art.
  • the radial press according to the invention has two cross slides, so that each press yoke is assigned its own cross slide. In this way, a radial press with a double press stroke results without the overall size increasing too much.
  • a radial loading opening is provided (see below). Furthermore, with such a radial press according to the invention equipped with two transverse slides, it is advantageous that - with a symmetrical structure of the press - the press axis does not move during the pressing process. This is particularly beneficial when the press is used in conjunction with an industrial robot.
  • a radial press according to the invention, equipped with two cross slides need not necessarily be constructed symmetrically. Rather, the deflection devices assigned to the two cross slides can be designed differently, for example by having wedge gears with different pitches. In this case, a cross slide with the associated press yoke for rapid adjustment and the other cross slide with the associated press yoke for force adjustment of the press jaws could be used.
  • the radial press has a common housing in which the at least one cross slide and at least one of the press yokes are guided. If the radial press according to the invention (only) has a cross slide, the other press yoke is expediently fixed in the Housing stored. In the case of radial presses according to the invention with two cross slides, the housing is expediently designed in such a way that both cross slides and both press yokes are displaceably guided in it. In connection with the extremely compact construction of the radial press explained above, such a common housing leads to a high degree of rigidity, so that even comparatively small radial presses can work with high forces.
  • the structurally very compact design of the radial press according to the invention even enables the housing to have a one-sided radial loading opening in accordance with a further preferred embodiment of the invention. Even the interruption of the (otherwise generally largely closed) housing by such a one-sided radial loading opening does not lead to an impermissibly high reduction in rigidity due to the extremely compact construction of the radial press according to the invention.
  • the possibility of radial loading of the radial press is, however, a very considerable advantage in practice compared to those radial presses that can only be loaded axially, since in this way the radial press is also suitable for machining workpieces that, due to their complicated shape, cannot be handled by the tool can be pulled, for example when pressing in the middle of a hose.
  • the radial loading opening also makes this development of the radial press according to the invention particularly suitable for automated use, for example by arranging the radial press as a pressing tool on the arm of an industrial robot. The Due to its radial loading opening, the radial press can be guided from the side over pre-assembled workpieces stored in a suitable device.
  • the one-sided radial loading opening explained above is particularly preferably arranged transversely to the direction of movement of the press yokes to one another.
  • At least one press jaw adjacent to the loading opening is particularly preferably divided into two press jaw segments.
  • the feature characterizing the radial press according to the invention comes into play, according to which at least one cross slide acting on one of the two press yokes is provided for introducing the pressing forces into the pressing jaws; because this cross slide enables such a large stroke of the press yoke in question that the radial loading opening is opened without simultaneously leading to a large structural volume of the press.
  • This cross slide enables such a large stroke of the press yoke in question that the radial loading opening is opened without simultaneously leading to a large structural volume of the press.
  • the design according to the invention also enables a modular concept in which different radial presses (for example with / without radial loading opening, different strokes, different drives) can be produced with a high proportion of identical components.
  • the at least one cross slide is designed as a hydraulic piston, which is sealingly guided in a section of the housing designed as a hydraulic cylinder.
  • the hydraulic piston performing the function of the transverse slide can itself be embodied in a wedge shape in order to provide a wedge gearing which converts its movement into a movement of the press yoke in question.
  • the cross slide also combines the functions of the hydraulic piston of the drive unit and an inclined guide of the deflection device; the result is the highest degree of compactness of the radial press.
  • the cross slide designed as a hydraulic piston in accordance with the development of the invention explained above can in particular have at least one longitudinal bore — designed as a blind bore, in which a piston rod is guided in a sealing manner. If a longitudinal bore with a piston rod is provided for each cross slide, the latter has a sealing head which divides the longitudinal bore of the cross slide into two hydraulic working spaces. Each of the two hydraulic work rooms is located with one the piston rod penetrating hydraulic channel in connection. In this way, without this increasing the size of the radial press, a so-called rapid drive is produced, with which the cross slide can be pulled back to open the press and can be advanced when the press closes at a relatively high speed and relatively little force until the press jaws come on fit the workpiece.
