Definitions

  • the invention relates to a method for producing a box-shaped box body for transport vehicles.
  • Such structures are already known in different embodiments. So you know box bodies, which are composed of individual, plate-shaped elements and connected in the edge areas, if necessary also in the flat areas, by means of rails. The assembly of such a box body is very time-consuming and therefore expensive. In addition, there is a comparatively high weight in the commonly used wooden panels.
  • box bodies which consist of composite panels with a PU foam core and GRP layers laminated thereon. Such structures are extremely expensive and complex to manufacture. A common feature of all three variants of the case of prior art box bodies is that there is only a limited or difficult repair option due to the multitude of materials.
  • the outer skin made of thin aluminum can be easily damaged, for example by knots, but that then substantial repairs are required for a repair, namely the removal of the inner wooden casing in order to be able to reach the repair site. If the aluminum replacement profiles are repaired, welding is not possible without extensive assembly work, since otherwise the adjacent materials would not be able to withstand the heat load.
  • the object of the present invention is to create a method for producing a box body which is particularly simple and quick to carry out and which requires only little mechanical outlay.
  • a case structure produced after this should have good tightness and weatherproofness, be light in weight and, if necessary, be easily recyclable.
  • a device for? Manufacture of a suitcase structure can be created, which is simple in construction and inexpensive and which is also easy to use, if necessary, by non-specialists.
  • a flat part consisting essentially of thermoplastic material, a support core and having a support core on both sides of this cover layer, the surface of which corresponds to at least two adjoining peripheral sides of the box body, in approximately lim ⁇ n-shaped areas corresponding to the edge boundaries of the adjoining ones , surrounding side walls of the box body are heated and folded there.
  • the essential assembly work for assembling the case consists in bending or bending a correspondingly dimensioned sandwich flat part under the influence of heat, so that afterwards at least the essential part of the case is practically available in one piece.
  • thermoplastic "material, multi-layered, a support core and having sandwich panels on both sides of these cover layers are joined together thermoplastic to form the flat part, whereby for this purpose a support core area for forming a receiving groove and of on one of the end faces to be connected the other sandwich panel stirnendig the covering layers partially removed and the core portion is inserted into the receiving groove 'and two de Sandwicholatten then under pressure and heat influence each other connected / earthed.
  • sandwich panels can be mass-produced practically irrespective of the size of the flat part and in terms of size.
  • the sandwich panels used can be produced practically endlessly in a specifiable width and can then be cut to length according to the circumferential length of a box body. If the width of the sandwich panel strand is not sufficient, a corresponding number of additional sandwich panel strands can be added to the side in the manner described above.
  • a support member from the mutually facing ends of the zi connecting walls. and from the other wall the end layers of the cover layers are removed in certain areas and that the cover layers of the support core-free region overlap is at least thermoplastic bonded to the top layer-free area of the other wall.
  • thermoplastic material is also welded here by the influence of heat and no additional connecting elements are required.
  • An advantageous embodiment of the invention provides that a preferably thermoplastic tube is inserted into the flat part, at least in the area of an intended development, and that the tube is warmed to bend the flat part and then the bending takes place.
  • the pipes used can be used as installation channels, especially for electrical wiring.
  • the heat can be supplied in the pipe area and in particular through the pipe. This supply of heat through the tube plastifies the bending area from the inside and is therefore particularly effective and quick.
  • the bending areas are determined by the position of the tubes and these form an additional edge stabilization.
  • the end profile can be formed by an aluminum profile, for example a square tube.
  • a profile made of thermoplastic can be used, which can be thermoplastic welded to the sandwich panel.
  • thermoplastic pipe is slit lengthways and provided with heating wires at the slit edges, that the pipe with the slit faces the inside of the bend in the area of an intended curvature between adjacent walls m the flat part or the sandwich panel (s) is used and that the slot edges are then placed together during thermoplastic bending and then fused.
  • an additional reinforcement of the corner areas can be achieved by melting together the slot edges spaced apart in the starting position in accordance with the intended bend. The necessary bending force is reduced during the bending process itself.
  • the invention also relates to a box-shaped box body for transport vehicles manufactured according to the method according to the invention.
  • This box body is characterized by walls bordering one another in at least one circumferential direction of the box body, forming at least an angular or U-shaped partial box body, which consist in one piece of a thermoplastic molded flat part having a support core with outer cover layers, and that the other, adjoining edges thereof and optionally other walls, in particular thermoplastic, are connected to one another.
  • the case structure provided provides considerable advantages in addition to the manufacture when used in conjunction with vehicles.
  • the box body has a high stability due to the use of sandwich panels at the same time low weight, the low weight being further favored by the elimination of the otherwise necessary connecting means such as connecting rails, corner rails, screws, angles and the like.
  • the weight can be reduced by more than 50%. For vehicles, this means a significant increase in the payload and thus the economy.
  • the thermoplastic, material connection of the case walls makes the case structure leakproof and weatherproof.
  • fastening elements are provided with an approximately spherical cap-shaped carrier body made of thermoplastic material, that the carrier body has on its concave side a transverse pin, preferably made of steel, spaced apart from the base of the carrier body, and its convex side is thermoplastic connected on the inside to a wall of the box body and engages the wall at least in some areas.
  • Such fasteners can be attached at any point on the box body, a thermoplastic welded connection being provided here as well.
  • the support body and the wall attachment point can be heated accordingly and the connection is made by pressing the two parts together.
  • Such fasteners are particularly well suited for lashing loads, for which purpose the fasteners are expediently arranged in rows on the inside of opposite walls of the box body and then practically form a replacement for the usual lashing rails.
  • the sandwich panel (s) has one or more compression areas produced by hot deformation as connection points for connecting sandwich panels to one another and / or for connecting to other parts, and that in these compression areas the cover layers are spaced apart from them by the support core Starting position, have a compression position with at least a reduced distance.
  • the box body has a high stability at these connection points due to the compression under the influence of heat, so that a corresponding power transmission is possible.
  • the connection points do not form a weak point within a composite system and the good strength properties of the sandwich panel or the case structure formed therefrom also have an effect on the overall construction. It is also important here that the two cover layers are included in the connection area and thus for the transmission of the force. Since the force is essentially absorbed through these cover layers, this is essential for high stability in the connection and connection area.
  • the invention also relates to a device for carrying out the method and for producing a box body.
  • This device is characterized in that it has a support for a sandwich plate consisting of essentially thermoplastic material, a support core and having cover layers on both sides of this cover layer, or a flat part formed of several sandwich panels connected to one another, and that the support has a heating zone on at least one of its edges.
  • thermoplastic flat parts or the like can be shaped, in particular folded, in a particularly simple manner, the thermoplastic plate being positioned on the support such that it lies along the heating zone with the intended bending area. If the heating zone is activated, the plate area protruding from the heating zone on the rare side can be angled with sufficient heating. In the simplest case, this is done by gravity, so that bending drives are generally not required. If necessary, the bending process can then be supported by hand.
  • An embodiment of the device according to the invention provides that the support is essentially formed by a support frame which has at least one heatable tube arranged at the edge as the heating zone.
  • a bending device can thus be implemented with little effort.
  • the cross-sectional shape and position of the heatable tube can be adapted to the respective requirements.
  • the support frame has heatable tubes arranged on the edge, preferably parallel opposite one another, which are preferably adjustable at least in their distance from one another. This means that thermoplastic sheets with areas spaced apart from each other can be folded at the same time.
  • the support frame is arranged in the course of a production line for box bodies and in particular adjoins a feed table for a flat part consisting of one or more sandwich panels and a subsequent roller conveyor for the removal of the part box body.
  • a feed table for a flat part consisting of one or more sandwich panels and a subsequent roller conveyor for the removal of the part box body.
  • the device for connecting flat part edges or sandwich plates that abut one another on the oblique side can have a pressing device with heated pressure stamps and / or heatable pressure rollers, which can preferably be positioned and pressed on opposite sides of the connection point of sandwich plates or flat parts.
  • connection points can be acted upon under the influence of heat in such a way that, on the one hand, material, thermoplastic welding and, on the other hand, consistently flat outer surfaces are formed.
  • the pressurization also results in a certain material compression, which contributes to a high stability in the connection area.
  • thermoplastic welding via integrated heating wires and the deformation for flat, continuous outer surfaces by means of pressure jaws or rollers.
