Definitions

  • the invention relates to a method for producing a door leaf according to the preamble of the appended claim 1. Such a method and such a door leaf are known from the US-A-5897796 removable.
  • the DE 94 14 135 U1 describes a steel sheet door, in particular in fire protection training, with two sheet metal elements, namely one forming a door leaf broadside box and the other door leaf broadside forming lid.
  • the lid is connected at its edge regions with parallel to the broad side plane outwardly projecting edge strips of the box edges by spot welding.
  • An adjoining the connecting zone to the outside edge portion of the edge regions of the lid or the edge strips of the box edges is angled towards the formation of a stop region of a rebate on the box and engages over the connection zone.
  • the edge region of the lid has a first, one in its width, the ceiling of the fold-determining web forming bend and a second, the stop area forming angling, the latter the connection zone, are welded together in the box and cover by spot welding, in approximately web width spaced overlaps.
  • the cover is initially not completely transferred in its final angled configuration with respect to its prefolded edge region, so that the connection zone between edge strips of the box and the edge region of the lid so accessible after placing the box on the lid from both sides is that a spot welder can be set accordingly.
  • the prepared folded stop zone of the lid is further bent towards the box, so that the two bends of the edge region of the lid overlaps the point-welded connection zone between the edge strip of the box and the edge region of the lid at a distance.
  • the DE 94 14 135 U1 directed please refer to the DE 94 14 135 U1 directed.
  • the outwardly projecting edge areas of the lid and the box are also angled after spot welding such that the angled sections form a door rebate of the sheet steel door. Not only the edge area of the lid, but also the edge area of the box is angled at least once.
  • An object of the invention is to provide a suitable for the manufacture of fire doors manufacturing method referred to in the preamble of claim 1 type, with the door leaves in thick fold training or other door panels with a cavity enclosing the edge area are easier and less expensive to produce ,
  • the two existing sheet metal door leaf elements - box and lid - are joined together. This is preferably done by superimposing or superimposing the further preferred already (at least partially) pre-folded door leaf elements. Subsequently, the edge region of a first door leaf element is brought into its intended final shape, ie here angled so that the edge region of the first door leaf element surrounds the edge region of the second door leaf element at least partially overlapping. So here are the first door leaf elements folded after assembly and before joining. Subsequently, the then overlapping edge regions of the door leaf elements are welded overlapping from the outside by means of beam welding. This creates a welded overlap connection as in spot welding.
  • a great advantage of beam welding is that it can be done completely from the outside and without the need for engagement from the other side of the weld joint. Due to the Umfalzens the edge regions to each other, these are already pre-fixed and - if necessary after a centering - in an appropriate position to each other. In this way, can be completely dispensed with compressive clamping tools. If this proves to be advantageous or even necessary in individual cases with regard to the quality of the weld seam, a possible bending of the sheets during welding is prevented by fixing from the outside.
  • the centering operation can be achieved, for example, by simultaneous bending of the outer edge regions of the first, lying on opposite sides of the first door leaf element Door leaf element with located therebetween second door leaf element. The second door leaf element is thus centered between the angles to be bent each opposite outer edge regions.
  • the production process according to the invention is particularly suitable for producing door leaves in Dickfalzaus Unit.
  • the fold region of such a door leaf encloses a (empty or with filling materials, such as insulation materials, filled) cavity.
  • filling materials such as insulation materials, filled
  • great development efforts have been made to produce such door leaves.
  • spot welding was only on in the DE 94 14 135 U1 way shown, ie first box and lid were welded edge, then there was a bend of the protruding edge region to the thick fold.
  • jet welding saves the use since beam welding does not require an abutment and no other access to the inside of the thick rebate.
  • the edge regions which are completely angled away from one another in the relative position relative to one another, are preferably further welded by means of a laser welding apparatus.
  • the beam welding apparatus may be part of a manufacturing device for the door leaf, which further comprises a loading device for inserting the second door leaf element in the first door leaf element and a Umfalzvorraum for bending the edge regions of the first door leaf element around the edge regions of the second door leaf element.
  • the beam welding apparatus may comprise a stationary or movable laser welding head or a laser with special radiation optics.
  • the laser head or the beam optics can also be installed fixed, in which case the manufacturing device a conveyor system for the assembled door leaf elements, with which the assembled door leaf elements are conveyed relative to the beam welding apparatus.
  • the overlapping sheets were successfully welded in the seaming area without additional materials.
  • the quality of the weld can be positively influenced by the feed rate and the intensity of the radiation.
  • the advantage here is that welds high strength - even with higher strength than the starting material - arise, which do not need to be reworked. Any distortions of the welded surface can be covered on the visible side by a subsequent powder coating. It has thus surprisingly been found that the beam and in particular the laser welding method is fully comparable with respect to its quality with the previously used spot welding process. With regard to the handling can be achieved by the laser welding a simplification, since the sheets can be angled immediately at the time of assembly and are then ready in a pre-fixed position for the laser welding process available.
  • the method can also be carried out in a continuous manner, for example by successively folding over the edge of the lid placed on the box, in particular for embracing the edge of the box, and then blast-welding.
  • a continuous manner for example by successively folding over the edge of the lid placed on the box, in particular for embracing the edge of the box, and then blast-welding.
  • the method is particularly advantageous for producing door leaves provided with a rebate on at least one door leaf narrow side, but can also be used for producing door leaves with obtuse peripheral or narrow sides, wherein one of the door leaf elements engages around the other door leaf element with its edge region.
  • the steel guide head or the beam guiding optics of a beam welding device is brought to the welding point only from the outside.
  • the shape of the sheets at the edge ensures that an overlap takes place.
  • Many laser welders require a minimum gap of the overlapping door leaf elements to be joined at a maximum of 0.2 mm or less. This is according to the invention by the previous Abkantreae and possibly subsequent centering operations on the edge region, in particular at the rebate, guaranteed.
  • the beam welding processes enable a precise energy input with minimal distortions and minimal damage to the weld area.
  • the welding depth can be determined by known methods - see for example the DE 40 27 714 C2 and the prior art referred to therein - check, for example, such that the sheet metal part remote from the welding device is not completely welded through, and thus a corrosion protection layer lying on the inside is not damaged. Should there nevertheless be a tendency for the sheet metal parts to diverge despite any bias that may occur as a result of the folding or angling, the marginal area being pressed against one another, this can be prevented by additional external fixings during the welding.
  • the manufacturing apparatus for carrying out the method, there are a number of beam guiding heads on the market.
  • beam guiding heads which allow a working distance to the weld of up to 280 mm.
  • angles of attack with respect to the object can be varied within wide ranges.
  • Another advantage of the use of the beam welding method is that with this method not only overlapping of sheets of steel, but also sheets of other metals, such as in particular aluminum or aluminum-based sheets are welded together. Also, sheets of different materials are welded together, even in the lap joint without filler material. As a result, it is also possible to produce door leaves with different sheet metal qualities on their two broad sides in a simple manner, for example those which have a stainless steel sheet on one side and a hot-dip galvanized sheet on the other side.
  • FIG. 1 - 6 Various embodiments of a produced by a beam welding method, namely here a laser welding process, door leaf are shown, which has a half shell, here in the form of a lid 2 and a second door leaf element, a second half-shell, here in the form of a box 1 as a first sub-element.
