Definitions

  • the invention relates to a thermoforming tool for forming soils of two-piece cans, in particular beverage cans, but also aerosol cans.
  • Can production is high volume production where high reliability is important.
  • the beverage cans are produced there each in a multi-stage shaping process, which includes, inter alia, a step for producing a cup shape, which is referred to as a cup.
  • the prepared cups are first ironed in a further shaping process and then deformed at their bottom. This deformation process is a deep-drawing process that is performed on the thin-walled, relatively filigree uncut box. After performing the bottom forming operation, the semi-finished box must be removed from the thermoforming tool and transported further. You must neither get stuck in the thermoforming tool, nor move uncontrollably.
  • the plunger is preferably provided with ventilation openings to allow air to escape from the can as the plunger retracts into the semi-finished can.
  • the lower mold part is provided with a lifter which separates the semi-finished can from the central mandrel and the hold-down ring after completion of the bottom forming operation and leads to a defined position .
  • the ejector is preferably moved by a relatively weak spring means. The movement that he performs overall is preferably greater than the stroke of the hold-down.
  • the lifter closes with the hold-down with open thermoforming tool preferably on an upper level.
  • the ejector is flush with a lower edge of the molding surface of the blank holder.
  • the lifter goes through each stroke a path that is the sum of Niederhalterhub and Ausheberhub.
  • the hold-down and the lifter are each formed annular or sleeve-like. Preferably, they are concentric with each other and arranged concentrically to the centrally located dome.
  • the hold-down device and the ejector are preferably arranged so as to be movable axially relative to one another.
  • the spring means provided for actuating the lifter is preferably supported between the hold-down device and the lifter.
  • the spring means consists of a plurality of compression springs, which are arranged in pockets provided for the lifter and axially oriented.
  • FIG. 1 a machine 1 is illustrated, which is used for can production and there performs at least the step of forming the can floors, but optionally also performs the so-called stripping.
  • the machine 1 comprises a tool 2 to which an upper tool part and a lower tool part 4 belong.
  • the upper tool part is formed as a punch 3 and fixed to a plunger 5, which performs according to arrow 6, a reciprocating motion.
  • the lower tool part 4, however, is arranged, at least preferably, stationary, so that the tool 2 continuously opens and closes according to the periodic movement of the plunger 5.
  • the tool 2 is in the FIGS. 2 to 4 illustrated separately in different stages of work.
  • the punch 3 has, for example, a substantially cylindrical basic shape, its lower end face facing the lower tool part 4.
  • the punch 3 and the tool part 4 can, as in FIG. 1 represented, side by side or alternatively also be arranged one above the other or in another orientation to each other.
  • the end face 7 of the punch 3 corresponds to the inner shape of the container bottom to be produced.
  • a central concave surface 8 seen from the outside is surrounded by an annular rib 9, which is adjoined by an annular, approximately conical, preferably slightly concave outer surface 10. This connects to the cylindrical shell 11 of the punch 3.
  • the lower tool part 4 has, corresponding to the punch 3 and its shapes, in particular the shapes of the end face 7, in the center a fixedly arranged dome 12. This has on its side facing the end face 7 on a surface 13, whose shape corresponds substantially to the shape of the surface 8.
  • the dome 12 is a separate one inserted in the lower tool part 4, preferably stationarily mounted element, the in the schematic representation according to FIG. 2 not further illustrated.
  • an annular hold-down 14 Around the dome 12 around an annular hold-down 14 is arranged. This has on the side facing the plunger 3 a forming surface 15, which is preferably approximately conical and is adapted in shape to the outer surface 10.
  • the molding surface 15 serves to act on an outer zone 16 of a bottom 17 of the container 18 during the forming process with a defined, directed against the punch 3 clamping force to control the transformation of the central region of the bottom 17.
  • the hold-down device 14 is movably mounted in the lower tool part 4. The direction of movement coincides with an arrow 19, which also indicates the direction of movement of the punch 3.
  • a die cushion 20 is provided, which is formed for example in the form of a pneumatic cylinder. This is preferably via a plurality of pressure pins 21, 22 with an end face of the blank holder 14 in abutment, which faces away from the punch 3.
  • annular gap is preferably formed, whose diameter preferably at least substantially coincides with the diameter of the rib 9.
  • a sleeve-shaped lifter 23 is arranged, which is movable in the direction of the arrow 19.
  • the lifter 23 has an upper annular preferably flat and integrally formed end face 24.
  • the hold 14 and the Ausheber 23 At rest, ie with open thermoforming tool 1 are the hold 14 and the Ausheber 23 in its highest possible position.
  • the lifter 23 rests against the hold-down 14 in the case of an annular shoulder 25.
  • a spring means 26, for example in the form of a first compression spring 27, a second compression spring 28 and optionally further not illustrated compression springs holds the lifter 23 in this position. This position is in FIG. 5 separately illustrated.
  • the upper end face 24 of the lifter is approximately at the level of the upper end 29 of the mold surface 15 or slightly above it.
  • the compression springs 27, 28 are supported at one end on the lifter 23 and at their respective other end on the hold-down 14 and a screwed-on ring 30 from this.
  • FIG. 2 on the left the corresponding recess introduced below into the lifter 23 is cut to receive the first compression spring 27.
  • the corresponding recess for the second compression spring 28 is shown hidden.
  • the punch 3 is moved away from the lower tool part 4 and thus out of the container 18.
  • the hold-down 23 leads the bottom 17 of the container 18 initially away from the surface 13.
  • the sticking of the container 18 to the hold-down 14 or its forming surface 15 is subsequently prevented by the lifter 23.
  • the spring means 26 pushes the container 18 on its bottom side molded rib further up.
  • the container 18 with finished bottom 17 is on the upper end face 24 of the lifter 23 and can thus be continued by a parts transport device for further processing.
  • a lifter 23 has been inserted, which is sleeve-shaped and disposed between downholder 14 and dome 12.
  • the ejector 23 is biased by a spring means 26 against the working direction of the punch 3 with a force which is substantially lower than the force exerted on the hold-down force.
  • the spring means 26 can by Compression springs 27, 28 may be formed, which may be arranged in front Axialausnaturalept the lifter 23. This release force can be varied by changing the compression springs or their number.
