Definitions
- the invention relates to a method for producing a door leaf according to the preamble of appended claim 1 and a door leaf which can be produced therewith according to the preamble of appended claim 15. Such a method and such a door leaf can be found in DE 94 14 135 U1.
- This publication describes a sheet steel door, in particular in fire protection training, with two sheet metal elements, namely a box forming the broad side of the door leaf and a cover forming the broad side of the door leaf.
- the edge areas of the lid are connected to the edge strips of the box edges which project outwards parallel to the broadside plane by spot welding.
- An edge section of the edge regions of the lid or the edge strips of the box edges adjoining the connection zone to the outside is angled towards the box to form a stop area of a fold and engages over the connection zone.
- the procedure according to DE 94 14 135 U1 is such that the cover, which has an original extension that extends beyond the edge strips of the box, is first placed on the bent edge strips of the box, which strive outwards, and with these is welded by spot welding. Then the edge section going beyond the edge strips of the box is bent back after spot welding.
- the edge area of the cover has a first bend forming a web defining the width of the fold and thereon a second bend forming the stop area, the latter being the connection zone in which the box and cover are welded to one another by spot welding overlaps about web width spaced.
- the lid is initially not completely transferred in its final angled configuration with regard to its pre-folded edge area, so that the connection zone between the edge strip of the box and the edge area of the lid after placing the box on the lid from both sides in such a way. It is common that a spot welder can be attached accordingly. Only after spot welding has been carried out is the prepared folded stop zone of the lid further bent toward the box, so that the two bends of the edge area of the lid overlap the spot-welded connecting zone between the edge strips of the box and the edge area of the lid with a distance.
- DE 94 14 135 U1 For further details, reference is expressly made to DE 94 14 135 U1.
- the edge regions of the cover and the box which protrude outwards are also angled in such a way after spot welding that the angled sections form a door rebate of the sheet steel door.
- the edge area of the lid, but also the edge area of the box is angled at least once.
- the manufacturing method according to DE 94 14 135 U1 is still considered to be in need of improvement in that a gap remains between the U-shaped angled edge portions of the cover and the peripheral surfaces of the box, which gap with regard to the visual appearance or viewed as disadvantageous with regard to a later powder coating of the door leaf.
- a shoulder on the peripheral surfaces - hereinafter also referred to as narrow sides or front sides of the door leaf - on which the leg end of the U-shaped edge portions of the cover rests to form a door rebate.
- Sheet steel doors used as interior doors have long been on the market, in which the box and the lid are glued to one another in the rebate area with their overlapping edge areas. This training is only suitable for normal purposes and not for fire doors. In addition, large quantities of adhesive are required for mass production.
- An object of the invention is to make a manufacturing method of the type mentioned in the preamble of appended claim 1 that is also suitable for manufacturing fire protection doors simpler and with less effort.
- Another object of the invention is to provide a manufacturing method of the type mentioned in the preamble of claim 1, with which door leaves with a thick rebate configuration or other door leaves with an edge region enclosing a cavity can be produced more easily and with less effort.
- a door leaf that can be produced with such a method is the subject of the subsidiary claim.
- the two door leaf elements made of sheet metal - box and lid - are first put together. This is preferably done by superimposing or pushing the door leaf elements, which are more preferably already (at least partially) pre-folded.
- the edge region of a first door leaf element is then brought into its intended final shape, ie angled here in such a way that the edge region of the first door leaf element at least partially overlaps the edge region of the second door leaf element.
- the door leaf elements are first folded after joining and before connecting. Then the overlapping edge areas of the door leaf elements are welded overlapping from the outside by means of beam welding. In this way, a welded overlap connection is created as in spot welding.
- a great advantage of beam welding is that it can be done entirely from the outside and without the need for intervention from the other side of the welded joint. Due to the folding over of the edge regions to one another, these are also already pre-fixed and - if appropriate after a centering process - are in a suitable position with respect to one another. In this way, compressive clamping tools can be completely dispensed with. If this proves to be advantageous or even necessary in individual cases with regard to the quality of the weld seam, any bending of the metal sheets during welding is prevented by fixation from the outside.
- the centering process can be carried out, for example, by simultaneously angling the outer edge regions of the first lying on opposite sides of the first door leaf element Door leaf element with a second door leaf element located between them. The second door leaf element is thus centered between the opposite outer edge regions to be angled.
- the manufacturing method according to the invention is particularly suitable for manufacturing thick rebate door leaves.
- the rebate area of such a door leaf encloses a cavity (empty or filled with filling materials such as insulation materials).
- great development efforts have been made to manufacture such door leaves.
- welding processes such as spot welding processes, this was only possible in the manner shown in DE 94 14 135 U1, i.e. First, the box and lid were welded on the edge, then the protruding edge area was bent to form the thick rebate.
- the use of beam welding processes saves you the effort, since with beam welding processes you do not need a counter bearing and no other access to the inside of the thick rebate.
- Embodiments of the invention use, for example, electron beam methods or preferably a laser welding method as the beam welding method.
- the edge regions which are angled in the intended relative position to one another are further preferably welded using a laser welding apparatus.
- the beam welding apparatus can be part of a manufacturing device for the door leaf, which also comprises an insertion device for inserting the second door leaf element into the first door leaf element and a folding device for angling the edge regions of the first door leaf element around the edge regions of the second door leaf element.
- the beam welding apparatus can have an immobile or movable laser welding head or a laser with special beam optics.
- the laser head or the beam optics can also be installed stationary, in which case the manufacturing device has 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 in the rebate area were successfully welded without any additional materials.
- the quality of the weld can be positively influenced by the feed rate and the radiation intensity.
- the advantage here is that welds of high strength - even with higher strength than the starting material - are produced, which do not have to be reworked. Any warpage of the welded surface can be covered on the visible side by a subsequent powder coating.
- the quality of the beam and in particular the laser welding process is fully comparable to that of the spot welding process previously used.
- a simplification can be achieved by the laser welding process, since the sheets can be angled immediately when they are joined and are then ready for the laser welding process in a pre-fixed position.
- the method can also be carried out continuously, for example by successively folding over the lid edge placed on the box - in particular for gripping the box edge - and then beam welding.
- door leaf bodies of different heights or different widths, including two-fold folds could be produced by converting quasi an endless belt and then separating them into individual door leaves with a suitable height or width without retrofitting or with only a small retrofitting of the manufacturing device.
- the method is particularly advantageous for producing door leaves provided with a fold on at least one narrow door leaf side, but can also be used for producing door leaves with bluntly designed peripheral or narrow sides, one edge of the door leaf element encompassing the other door leaf element.
- the steel guide head or the beam guide optics of a beam welding device are only brought to the welding point from the outside.
- the shape of the sheets at the edge area ensures that there is an overlap.
- Many laser welding devices require a minimum gap of the overlapping door leaf elements to be joined together of at most 0.2 mm or less. According to the invention, this is guaranteed by the previous bending processes and possibly subsequent centering processes at the edge area, in particular at the fold area. advantage.
- the beam welding methods enable a precise energy admission with mi- 1 nimalen distortions and minimal adverse effects on the weld area.
- the welding depth can be checked using known methods - see, for example, DE 40 27 714 C2 and the prior art mentioned therein - for example in such a way that the sheet metal part remote from the welding device is not completely welded through and thus does not have a corrosion protection layer on the inside is damaged. Should there nevertheless be a tendency for the sheet metal parts to diverge in spite of a possible pre-tensioning caused by the bending or angling, which presses the edge areas against one another, this can be prevented by additional external fixings during the welding.
- beam guiding heads on the market for constructing the manufacturing device for carrying out the method.
- laser welding heads that allow a working distance from the welding point of up to 280 mm.
- the angle of attack in relation to the object can be changed over a wide range.
- first prototype beam welding machines that allow welding beam deflection with movable reflector elements, as has been known for a long time in laser marking systems.
- Another advantage of using the beam welding process is that this process can be used to weld not only overlap connections of steel sheets, but also sheets made of other metals, such as, in particular, aluminum sheets or sheets based on aluminum. Sheets made of different materials can also be welded together, even in an overlap joint without any additional material. As a result, door leaves with different sheet metal qualities can also be produced in a simple manner on their two broad sides, for example those which have a stainless steel sheet on one side and a hot-dip galvanized sheet on the other side.
- 1 - 6 cross sections through a circumferential area, provided with a fold, of a door sheet made of sheet metal, in particular sheet steel, produced by means of a beam welding process; 7 shows a peripheral surface area of a door leaf formed from sheet metal that is made blunt during a welding process; and
- FIG. 8 shows various steps for producing a door leaf according to FIG. 2.
- 1-6 show various embodiments of a door leaf manufactured using a beam welding process, namely here a laser welding process, which as a first partial element is a half-shell, here in the form of a cover 2 and as a second door leaf element a second half-shell, here in the form of a Box 1 has.
- the two door leaf elements 1, 2, which consist of sheet metal, namely here of coated or uncoated steel sheet, are welded to one another at their edge regions 3, 4. They enclose a door leaf interior 5, which is filled with conventional insulation or fire protection materials (not shown).
- the two door leaf elements 1 and 2 are formed from sheet metal, namely sheet steel here.
- the box 1 forms the door leaf broad side 6 of the door leaf and the cover 2 forms the other door leaf broad side 7 of the door leaf.
- the door leaf is provided with a fold 9 - in the form of a thick fold enclosing a cavity.
- the fold 9 has a stop area 10 for the door leaf.
- the box 1 has a step on its edge region 3 with a first step section 11 running parallel to the door leaf broad side 6 and a second step section 12 adjoining it perpendicular to the door leaf broad side at a distance from the stepped region of the narrow side 8 ,
- the edge area 3 of the box 1 is thus angled twice in relation to the non-stepped area of the narrow door leaf 8.
- the edge region 4 of the cover 2 is angled twice in order to form the fold 9.
- a first bend forms a web 19, the width of which determines the thickness of the fold 9.
- the second bend 20 forms or has the stop area 10 of the fold 9.
- the edge region 4 of the cover 2, with its two bends 19, 20, encompasses the two step sections 11 and 12 of the edge region 3 of the box 1 forming the step.
- the sheets 1 and cover 2 forming the sheets lie overlapping one another at these edge regions 3 and 4 to each other.
- the box 1 and the lid 2 are welded at their overlapping edge regions 3 and 4 by a laser weld seam 21 in the region of the stop region 10.
- the laser weld seam 21 connects the second bend 20 of the edge area 4 of the cover 2 to the first step section 11 of the edge area 3 of the box 1.
- only the edge sections of the edge areas 3 and 4 located at the stop area are laser welded together.
- the embodiment according to FIG. 4 corresponds essentially to the embodiment according to FIG. 1, but here the second step section 12 at the edge area 3 of the box is shorter than the web 19.
- the box 1 thus does not extend over the entire thickness of the door leaf.
- the two door leaf elements 1 and 2 are held here by a filling, not shown, which is clamped between the two door leaf elements 1 and 2 in the door leaf interior 5 and the first laser weld seam 21 made after the edge region 4 has been bent into the overlap with the step of the edge region 3.
- the embodiment according to FIG. 5 essentially corresponds to the embodiment according to FIG. 2, but here a strip section 24 running parallel to the region of the cover 2 forming the door leaf broad side 7 is also connected to the second step region 12.
- the strip section 24 runs parallel to the door leaf broad sides 6, 7. It serves as a supporting support for the cover 2. The distance between the flat region of the box 1 forming the door leaf broad side 6 and the strip section 24 determines the door leaf thickness.
- the two edge regions 3 and 4 of box 1 and cover 2 run parallel to one another and are oriented in the same angled striving.
- the door leaf narrow side 8 of the box 1 has no step in the embodiments according to FIGS. 3 and 6.
- the edge region 3 of the box 1 protrudes outwards at the level of the inside of the flat region of the cover 2 which forms the door leaf broad side 7.
- the edge area 3 of the box 1 is here provided with a first bend 25, which rests on the flat area of the cover 2 forming the door leaf broad side 7, and with a second bend 26, which is angled parallel to the web 19 of the cover 2 and runs against it is.
- the angled portion 25 is connected by a laser weld seam 27 to the flat region of the cover 2 which forms the broad side 7 of the door leaf.
- Another laser weld seam 28 connects the web 19 to the second bend 26.
- the edge regions 3 and 4 end with the second bend 26 of the box edge region 3 or with the web 19 of the lid edge region 4.
- the fold 9 is thus left open on its support region 10 with a groove which serves to accommodate a door sealing element (not shown).
- the fold 9 is designed as a thick fold. With this design, the sheets of the box and lid in the rebate area are laser welded from the outside. This means that there is no need to provide tools that engage in the groove to form a counter bearing during the welding process. The groove can thus also be made very narrow.
- the two edge regions 3 and 4 are angled again, directed back towards the box 1. Accordingly, the edge region 3 of the box 1 has a third bend 30, which extends parallel to the second bend 20 forming the contact surface 10 of the fold 9 and is connected to it by a further laser weld seam 31.
- FIG. 7 shows, the overlapping arrangement and connection by means of laser welding is possible even if the narrow side of the door leaf 8 is blunt.
- the lid 2 and the box 1 are each provided with 2 bends at their edge regions 3 and 4, the two bends 19 and 20 of the lid 2 overlapping the edge region 13 of the box 1 and with this by means of laser welding - see the laser welding device with laser welding device 40 and movable reflector elements 41, 42 - connected.
- the box 1 and the lid 2 are first placed one on top of the other, the box 1 already being prefabricated with the step sections 11 and 12.
- the two bends 19, 20 of the cover 2 are bent into the intended position and thus the two door leaf elements 1 and 2 are fixed to one another, as is shown in sub-figure b).
- the two laser welding seams 21 and 22 are attached by means of laser welding heads 43 and 44 (part figure c).
- the laser welding heads 43 and 44 can be moved longitudinally to the door leaf, as indicated in sub-figure d).
- the laser welding seams 21, 22 can be continuous or, as shown in the partial figure d), interrupted.
- the laser welding head 43 or its optics is held stationary and the door leaf is moved away from it.
- a single welding head 43 is used to form both laser welding seams 21, 22, the laser welding head 43 being movable via a robot arm.
- electron beam welding can also be used.
