Definitions

  • the invention relates to a device for expanding and shaping can bodies, with a mandrel-like molding tool that can be inserted into the can body to be expanded from one side, and a counter tool.
  • the invention further relates to a method for expanding and shaping can bodies, in which a mandrel-like molding tool is inserted into a can body and moved against a counter tool.
  • This device has a hard and massive, block made of steel or any other harder material, cylinder-like cross-section, which along most of its height has a larger diameter corresponding to the inner diameter of the already expanded can body and a conical section on its upper part. A short section of reduced diameter is arranged above this conical section and corresponds to the inside diameter of the can body to be expanded.
  • the shaping block should be designed in such a way that it can be attached or accommodated to the can body to be expanded under pressure and adaptable.
  • the molding block may also have at its lower end its tool for forming a flange in the form of a steel disc, which is provided on its upper side with an annular groove trough-shaped cross section, which extends from the lower end of the cylindrical can body during expansion and shaping can be achieved and engaged.
  • the counter tool is used according to DE 100 40 173 AI to form a flange on the upper part of a can and also consists of a steel disc, which is provided on its lower, the molding block side with an annular groove trough-shaped cross-section and a small annular and projecting portion surrounding the inner periphery of the groove.
  • the protruding portion is engageably held at the top of the can body to be subjected to the expansion and molding process.
  • the can body By inserting the molding block into a prefabricated can body, the can body is formed on the outer surface of the molding block, the can body diameter being enlarged and a so-called "neck-in" being formed in a single processing step.
  • the mentioned grooves of the two steel disks slightly expand the respective can body end faces.
  • the can body shape corresponds to its outer jacket contour, ie the can body is cylindrical except for a slight upper area, the neck-in area.
  • a tool suitable for this purpose consists of a plurality of segments arranged in a circle, which carry the desired shape profile on the outside. If you insert the tool into the welded cylinder and move the mold segments radially outwards by means of a cone inside the tool, they widen and form the cylinder body.
  • the disadvantage of this method is that the cylinder body becomes polygonal and that the cylinder body material is locally stretched to a great extent, the frame shortening is uneven over the circumference and the expansion cannot be carried out to the end of the frame, because then there is no longer a sufficiently precise flange.
  • the embossing of shape designs can also be carried out with the so-called spin-flow shaping, which is a roll-print process that does not widen, but rather reduces the diameter of the welding frame at the shaping point. With this method, however, only simple rotationally symmetrical shapes can be produced.
  • the finished frame, the can body is produced with a diameter which is less than or equal to the smallest desired diameter of the finished part.
  • a first embodiment worked with two mandrel-like molds, which are inserted into the can frame on the opposite sides and deform the can frame by expansion and shaping until the respective end faces of the mandrel-like molds come to the end position.
  • the cross-sectional profiles of the two mandrel-like shaping tools are at least at their ends in partial areas a smaller distance from the longitudinal axis of the can than the corresponding partial areas further away from the mandrel end.
  • the mandrel ends have a maximum diameter which is smaller, the same or slightly larger than the diameter of the can body to be expanded.
  • the cross-sectional shape can taper towards the end of the mandrel at least over a partially axial region.
  • the end faces of the mandrel can be arranged or formed either perpendicular to the longitudinal axis of the mandrel, at an oblique angle, in a corrugated manner or in any other shape to the longitudinal axis of the mandrel. The latter also allows constrictions on the can frame to be formed which lie at an oblique angle, undulating or in any other shape with respect to the longitudinal axis of the frame.
  • the present invention also relates to a method using the mandrel-like molds described.
  • Fig. 1 is a schematic illustration of two mandrel-like
  • Molding tools that pass through are remotely movable, shown in the starting position before the frame deformation,
  • FIG. 2 shows a corresponding arrangement according to FIG. 1 with can forming tools which are moved towards one another over a partial stroke and
  • Fig. 3 shows the end position of the molds, in which the
  • Fig. 4 is a side view of the with a tool
  • Fig. 1 to 3 made frame profile
  • Fig. 10 shows a difference-widened, stackable frame with a rotationally symmetrical decorative shape.
  • the frame is welded to the smallest diameter of the shape profile or somewhat smaller and then brought to the final diameter outside the shape profile by inserting a molding tool on both sides or in special cases.
  • the shape of the mandrel ends and the mandrel determines the shape profile and the shell geometry. If, depending on the desired shape, the respective mandrel end is slightly larger or equal to the inside diameter of the welded frame, the can end should be lightly butted in an upstream forming step so that the mandrel can be inserted automatically. As can be seen in Fig.
  • two mandrel-like molds 1 and 2 which can be carried out through an opening of mutually opposite scrapers 3 and 4, serve as molds for the can frame 5, the ends of which are slightly conically bent, so that the mandrel ends of the Molds 1 and 2 can be easily inserted.
  • the open frame 5 is arranged in a manner known from the prior art between the wipers 3 and 4 by means of a conveyor, not shown, and is positioned relative to the longitudinal tool axis 6, which is also the longitudinal axis of the frame. In the state shown in FIG. 1, the mandrel-like molds 1 and 2 are in the upper and lower dead positions, respectively.
  • the molds 1 and 2 are moved towards one another in the direction of the arrows 7 and 8, respectively, and they widen the can frame 5 until the final state shown in FIG. 3 is reached.
  • the profile of the molds has been molded in a corresponding manner onto the can frame 5, which has a throat-like constriction 9 in its lower third, which is determined by the tapered profiles of the ends of the mandrel-like molds.
  • the end faces of the molding tools come to face contact in the final state shown in FIG. 3.
  • the molds 1 and 2 can be withdrawn again, the shaped frame remaining between the wipers 3 and 4 and then being conveyed away using transport means known in the art.
  • Fig. 5 shows a widened frame 10 with a shape as a protective bead 11, which can be formed by the fact that the mold inserted from below is guided almost to the other end of the frame opening and the mandrel-like mold is designed to be correspondingly shorter as a counter tool. In this case too, the end faces of the mandrel-like shaping tools that finally come to rest are aligned perpendicular to the longitudinal axis 6.
  • the constriction 13 as an annular profile, is not orthogonal to the longitudinal axis 6, but rather at an oblique angle or it is undulating. This is achieved by using two mandrel-like shaping tools with correspondingly configured mandrel ends, the end face of which is arranged in a plane lying at an oblique angle or undulating to the longitudinal axis 6 or in an obliquely angled, possibly curved surface. Since only widenings can be impressed into the can frame with the molding tools according to the invention, that is to say no undercuts, the conically tapering mandrel ends are to be designed in accordance with the desired shape of the constriction and its position.
  • the frame 14 shown in FIG. 7 is also asymmetrical and has two non-linear regions 15 and 16, in which it tapers to a smaller diameter, which in the intermediate region 17 extends through a certain one the mandrel end design given length dimension is constant.
  • the shape and position of the shape can generally be adapted to the printed image.
  • a rotationally symmetrical decorative shape and longitudinal profiles 19 can be seen, which are determined by the outer shell of the mold.
  • Two mandrel-like shaping tools can be used to produce this can body, the end faces of which come to the final deformation position in plane 20 within the can body.
  • a correspondingly enlarged configuration of the molding tool inserted from below can also create a lower shoulder 22 with an enlarged diameter, which can be the same or a different diameter as the upper cylindrical shoulder 23 of the frame.
  • the can frame 24 has an outer casing which, with the exception of small upper and lower sections 25, 26 with a cylindrical shape, extends in each case to the plane 27 and tapers, i.e. the can casing outer profile is largely concave.
  • FIG. 10 shows that two can bodies 5 according to FIG. 4 can also be stacked; The same applies to the other can frames.
  • the flared frame is circular with a corresponding mandrel design - apart from molded longitudinal profiles - and not necessarily polygonal.
  • the expansion of the sheet is uniform over the circumference, which allows a larger expansion with the same sheet elongation. There are no striking fluctuations in height. Formability is possible up to the end of the frame.
  • a desirably uniform reduction in sheet thickness occurs in the cylindrical part, while the original sheet thickness is retained in the shape-sensitive area.
  • the molds used are simple, robust and easy to retrofit or replace in existing systems if changed shape shapes are required.
  • the shape designs shown in the exemplary embodiments according to FIGS. 1 to 10 can be varied as desired, with deformation limits being small, apart from the general suitability of the sheet and the lacquer. As already mentioned, only undercut shapes cannot be created.
