Definitions

  • the invention relates to a method and a device for clamping and / or pressing an object with at least two tools.
  • the invention is therefore based on the object of proposing a method and a device which run or function with the highest precision.
  • This object is achieved in that only one of the tools is influenced from the outside against the object, while the other tools are pressed against the object while deflecting the direction of force of the first tool.
  • the operating force of the one tool is simultaneously directed to a preferably symmetrical lever mechanism, deflected there by 180 degrees and the second tool is moved in the opposite direction to the first tool. As a result, additional support of the object is not necessary.
  • Another very advantageous embodiment of the invention lies in the fact that the force acting from outside to operate the tools acts on two inclined surfaces arranged symmetrically to the force axis, which are moved towards one another and thus against the object under the influence of the operating force.
  • a device is characterized in that a first tool is slidably mounted on two parallel guides and is provided with a bridge, at which the operator is introduced in the middle and the two ends of which are connected to two rotatably mounted levers, which in turn are connected to the second tool in Make a connection and move it in the opposite direction to the first tool.
  • the force introduced into the first tool is divided and a part is deflected through the rotatably mounted levers by 180 degrees, whereby the second tool loaded with this part moves against the first tool, the object to be clamped or pressed between both tools is clamped.
  • a further device is characterized in that two symmetrically arranged surfaces are arranged on a first longitudinally displaceably mounted tool, which are connected to inclined surfaces arranged on two further tools and move these against each other.
  • two additional tools are controlled synchronously by one tool, so that simultaneous engagement of all tools on the object to be clamped or pressed is ensured.
  • the symmetrical surfaces provided on the first longitudinally displaceable tool are designed as rotatably mounted rollers. This enables particularly easy operation of the other tools.
  • a further advantageous embodiment of the invention is characterized in that two push rods are attached to the bridge of the first tool, which are connected at their end by means of a crossbar which carries two plungers, each with one end with one arm of the rotatably mounted Levers are connected, the other arm of which is connected to a bridge of the second tool via push rods.
  • This embodiment of the invention enables a largely loss-free deflection of the actuating force for the second tool.
  • the further tools are each mounted on two parallel guide rods. This ensures a perfect parallel movement of the individual tools and thus an exact grip on the object.
  • two compression springs are arranged between the two further tools, the windings of which extend around the parallel guide rods. This ensures that the two tools return to their starting position removed from the object after being relieved by the first tool.
  • a further embodiment according to the invention is that the further tools are provided at their end facing the first or second tool with a contact surface with which these tools rest against the first or second tool in their retracted end position. This on the one hand prevents the object from being overstretched by the other tools, but on the other hand ensures that the object is completely pressed.
  • the inner tool is provided with an inner bore and radially extending slots extending therefrom, which subdivide the inner tool into individual segments, and if an axially displaceable punch is provided in the interior of the inner bore, which the internal tool expands when retracted. This makes it possible to apply the external tools to the object without considerable pressing pressure and then to generate it by the stamp of the internal tool.
  • the inner tool is designed as a sonotrode of an ultrasonic welding device.
  • FIGS. 1, 2 denote an oval can in FIGS. 1, 2, which is wound from a one-piece blank 2 of cardboard and is closed along a longitudinal seam 3.
  • the cardboard blank is coated with plastic and can therefore be welded or sealed.
  • the can 1 is closed with an identical cover 4, which is slightly drawn inwards.
  • the edge 5 of this cover is U-shaped, so that the respective end of the jacket blank 2 can be enclosed in this edge 5 and sealed with it.
  • the device 10 shown in FIG. 3 for sealing the lid into the can has a first tool 11, one end of which is provided for engaging the edge of the lid 4 and is designed accordingly.
  • the other end of this tool is connected to a piston rod 12 of a cylinder 13 which presses the tool against the cover.
  • a bridge 14 is fastened to the tool 11, with which the first tool is mounted so as to be longitudinally displaceable on two guides 15 and 16 running parallel to one another.
  • a push rod 17, 18 is attached, both of which are also attached to the two ends of a crossbar 19.
  • two symmetrical lever mechanisms each one have rotatably mounted two-armed lever 20,21, one arm of which is connected to the crossbar 19 via a plunger 22,23 and the other arm of which is connected to a further bridge 26 via a further pushing plunger 24,25 to which a second tool 27 is fastened.
  • This second tool 27 works exactly the same way as the first tool 11, but to the same extent.
  • the bridge 26 is mounted on two guides 28 and 29 which run parallel to one another and are longitudinally displaceable.
  • Two rotatably mounted rollers 30, 31 and 32, 33 are provided on both bridges 14 and 26, which are arranged symmetrically to one another and act on inclined surfaces 34, 35 and 36, 37, respectively.
  • These inclined surfaces 34 to 37 are connected to two further tools 38 and 39, which act on two further opposite sides of the cover, whereby this is acted upon by tools over its entire circumference, the rollers 30 to 33 bringing these additional tools together via the Cause inclined surfaces.
  • These further tools 38, 39 are also connected by guide rods 40, 41, compression springs 42, 43 being wound around these guide rods, which press the two tools 38, 39 apart.
  • the two further tools 38, 39 are provided on both sides of their actual contact surface with a contact surface 44, 45 and 46, 47, respectively, with which these tools contact the already partially retracted first and second tools 11 and 27.
  • the device is also equipped with a central inner tool 48 which engages in the retracted section of the cover 4.
  • This inner tool 48 is provided with a central inner bore 49, in which a punch (not shown) engages, which is axially displaceable and conical. From the inner bore 49 extend radially outwardly extending slots 50 through which the inner tool is so flexible that it can be expanded by the punch. The pressure required on the lid edge for sealing can thus be applied by the inner tool. But it is also possible that To pull together the external tools even further, and to apply the welding pressure from the outside.
  • the heat necessary for welding the plastic cover to the plastic coating of the container jacket can be applied in that the inner tool 48 is designed as a sonotrode of an ultrasonic welding device. But it is also possible to apply the necessary amount of heat from the outside e.g. to be applied to the lid by hot air blowers or heat radiation.
