Definitions
- the present invention relates to a method for closing the edges in sandwich panels with a core made of plastic and cover layers made of metal or plastic on both sides, a sandwich panel processed by the method and a device for carrying out the method.
- edge seals are predominantly made using edge number pails (e.g. blockboard), edging profiles or filling the edges with subsequent sanding of the edges.
- edge number pails e.g. blockboard
- the edges of the sandwich panel have a relatively open structure with a honeycomb core or foam core. This provides inadequate structural surface for attaching edge profiles or for connecting to other panels.
- the object of the present invention is to provide a method for sealing the edges of sandwich panels of the type described above in a simple manner even more reliably, even if the core is made of non-thermoplastic material at least in the central part of the panel should exist.
- This object is achieved according to the invention in a method of the type defined in the introduction by the features of the characterizing part of claim 1.
- Particular embodiments of the invention are defined in the dependent claims.
- thermoplastic core material near the edge is melted in a controlled manner and, if necessary, the top layers (which may be reinforced with glass fibers).
- the contact pressure is maintained until the individual honeycomb webs lie on top of one another and consequently full material has formed.
- These webs are thermoplastic connected to each other by the advancing hot tool.
- the shape of the edge is determined by the shape of the hot tool. All known shapes (round, square, multi-level, oval, etc.) are possible.
- the edge contour created during the hot pressing process can also be machined after cooling. For example, a hole can be drilled into which a threaded insert is inserted. The compacted material has now created a local situation that has a high mechanical strength.
- the edge produced is very impact-resistant and, as an outstanding advantage, cannot be removed practically, since it is made from the composite of the plate and not from additional material. If the edge trim produced is damaged, it can be repaired simply and inexpensively by applying heated thermoplastic material (eg polypropylene) locally. After cooling, the excess material can simply be sanded mechanically.
- heated thermoplastic material eg polypropylene
- the invention also relates to a sandwich panel produced by the method and a device for carrying out the method.
- the latter is characterized by the features of the characterizing part of claim 10.
- the edge seal can also be e.g. be made as a tongue and groove connection. This makes it possible to string the sandwich panels together as required.
- the sandwich panel is fixed on the assembly table to produce the edge seal.
- the hot tool made of steel is located according to the desired side contour and can be rotated and moved.
- the contour is created by controlled movement to the side of the plate by melting and running the thermoplastic material to the end. After the cooling process, the side stop is retracted and the end is made.
- the method also works on curved or arched sandwich panels, even if the cover layers consist of non-thermoplastic material t, for example metal.
- the method according to the invention places low demands on the cutting of the sandwich panel and its angularity. It is simply melted a little more at the points that do not immediately touch the hot tool. Especially with large sandwich panels, a precise cut is included associated with high costs. This is not necessary in the method according to the invention.
- Figure 1 shows purely schematically the various process steps for closing an edge of a honeycomb core panel.
- FIG. 2 shows a representation similar to FIG. 1 of a variant of the method
- Fig. 3 shows a panel with a base core made of non-thermoplastic material, which core is replaced at the edge portions to be closed by thermoplastic material.
- FIG. 1 a shows a sandwich panel with a honeycomb core 1 and cover layers 2, 3 made of thermoplastic material, the right-hand edge 4 of which is to be closed. This is done by means of a tool 5 which can be used both as a hot pressing tool and as a cooling tool.
- a heating medium H is passed through the channel 6 to heat the tool 5. If the tool is used for cooling, the heating medium H is replaced by a cooling medium K.
- the panel is fixed on a table (not shown) and moved with the heated tool 5 against the edge 4 to be sealed.
- the contact surface 7 of the tool 5 is designed in such a way that the heated cover layer edge sections 2a, 3a are brought together and the honeycomb core edge section la (likewise heated and in melt) melts in a controlled manner under compression with the cover layer sections. This is illustrated by Fig. 1b. If the edge section created by the hot pressing process is now cooled (for example by the cooling tool according to FIG. 1c), the clean edge termination according to FIG. Id results.
- the compressed core material la is fused to the cover layer material 2a, 3a (the material of the cover layer edge sections 2a, 3a can also be slightly compressed).
- FIG. 2 of the drawing shows a variant of the method, the same reference symbols being used for the different parts as in FIG. 1.
- the tool can be provided with an auxiliary device 8 (shown in dashed lines) if necessary.
- Figure 3 of the drawing finally shows a panel with cover layers 2, 3 made of plastic or metal and a basic core 1 'made of a non-thermoplastic material.
- cover layers 2, 3 made of plastic or metal
- basic core 1 ' made of a non-thermoplastic material.
- the portions 1 "of the core 1 near the edge are replaced by thermoplastic material (honeycomb or foam structure).
- cover layers 2, 3 consist of thermoplastic preformable material
- an edge seal according to FIG. 1 can also be made here.
- cover layers 2, 3 consist of non-thermoplastic material, e.g. Aluminum or steel is to be followed to form the edge closure according to Figure 2.
