Abstract

The invention relates to a heavy-duty storage and processing block, consisting of plates (1) stacked flat on top of one another and glued to one another at their respective contact surfaces (2, 3). The invention is characterized in that the panels (1) are waterproof, glued multiplex panels, the structure of which is aligned parallel to the printing surface and each panel is pegged to the respectively adjacent panel.

Description

The invention relates to a Schwerlastlager- and processing block, according to the preamble of claim 1.

Heavy workpieces or machines are placed on mobile load carriers for further processing. The position d. H. The location of this load carrier is freely selectable and can therefore be used for any location and also for a variety of workpieces. With regard to their own weight, these may, despite their ability to take on heavy loads, not be too heavy themselves, so that they are also easily displaceable.

In the DE 3223282 C2 is a stackable load carrier described with the different substructure heights can be formed. Due to its spatial structure, this load carrier is only partially suitable for large loads. For the purpose of saving weight as a hollow body formed carrier, are also inadequate because of their low intrinsic stiffness and the associated vibration affinity. Therefore, formed as a hollow body metallic carrier have proven to be in total unsuitable.

In order to obtain a vibration-resistant workpiece carrier, which can absorb large loads and is easily displaceable, cube-shaped pads have been created, which are composed of individual plates. The plates are glued together. However, these cubes have a relatively short life, since the composite of the individual plates is not permanently guaranteed by the extremely high weight loads. The bond dissolves and the cubes split, so that when placing the workpieces, there is also a great risk of accidents.

The present invention is therefore an object of the invention to improve a workpiece carrier of the type mentioned in terms of its handling and its permanent applicability.

This is solved by a heavy load bearing and machining block according to the main claim. Further features of the invention are described in the dependent claims.

According to the invention, the heavy load bearing and processing block comprises stacked plates which are glued together at their respective contact surfaces.

The invention is characterized in that the plates are water-bonded multiplex plates whose structure is aligned parallel to the printing surface and each plate is pegged to the respective adjacent plate. This ensures that on the blocks of the invention z. B. such cast iron and steel parts can be stored for the purpose of processing them, which can have a weight up to 100 t. It is inventively achieved that the allowable load capacity of 1/3 of the support surface is at least 15 t, which in turn means that a force of 450 KN on 1/3 of the support surface on the edge of the block causes no damage. The aligned parallel to the pressure surface structure pattern of the plates prevents splitting at high weight loads.

By using beech wood as the board material, a high inherent hardness is achieved because beech wood is a heavy and hard wood with a Brinell hardness of 34 N / mm ² . With a selected gluing quality of AW 100, the gluing can be described as water-resistant. This is particularly important in order not to have to limit the variety of processing steps to be performed on the resting workpieces because of the support block properties.

The invention prefers for the gluing of the plates to each other a Holzkaltleim the minimum quality 1 K wood glue D4. This gluing is classified as a waterproof glue.

The block can be cube-shaped or quared-shaped, which can be varied by the number of individual plates.

The bearing surface is the area of the block that is subject to high wear. For this reason, the invention provides that the top plate, which forms the support layer, from a hard paper plate, preferably a Pertinaxplatte the minimum quality HP-PF CP 201 according to DIN EN 60893 is provided. This is interchangeable by means of stainless steel screws mounted on the top multiplex board.

In blocks with greater pitches is provided in a preferred embodiment of the invention that this is penetrated by at least one threaded rod having at its free end a nut which compress the outermost multiplex plates, including the intervening multiplex plates. This leads to an increased and permanent connection of the plates with each other.

In order to allow a practical handling of the blocks, the invention provides that the heavy-duty bearing and processing block has on at least two opposite sides in each case one, a carrying handle receiving trough. The handles are sunk in the trough and the entire engagement is flat, d. H. there are no obtrusive hardware over the outside.

In order to achieve the greatest possible horizontal alignment of the workpiece without shims and chocks, a high degree of height equality must be achieved even when combining a block group. Since, however, the multiplex plates have a relatively high thickness tolerance, the greatest possible height uniformity of all blocks must be achieved with the combination of different plate thicknesses. There may be a tolerance of max. +/- 1-2 mm occur.

The invention will be described below with reference to the drawings with reference to a preferred embodiment. In the drawings show:

1 a heavy duty storage and processing block according to the invention in a perspective view,

2 the heavy load bearing and machining block without upper wear plate and

3 a cross section of the heavy load storage and processing block.

The Schwerlastlager- and processing block has a cubic shape and is made up of individual stacked multiplex plates 1 together. To a workpiece, for. B. to store a heavy casting, preferably several such blocks are used. The multiplex plates 1 become one with each other at their contact surfaces 2 . 3 glued To achieve an additional durability of the connection, these are pegged together. For this purpose, preferably near the corner areas dowel holes 4 set and in the area of the respective plate contact surfaces 2 . 3 appropriate dowels 5 brought in. At relatively high bearing blocks is by the introduction of threaded rods 6 achieved an additional connection security. For this purpose, the multiplex plates are penetrated with preferably at the corner, near the dowels, each with a bore. Both the lowest multiplex panel and the upper multiplex panel 1a be with a Senkbett 7 provided in the one on the threaded rod 6 mother turned up 8th to come to rest. Supporting here is a washer 9 be used. The bearing surface 10 is from a hard paper plate 11 , preferably a Pertinax plate, formed. This is done by means of the screws 12 on the underlying multiplex board 1a attached. The finished block will be on its opposite sides 13 . 14 milled out and in the troughs formed thereby 16 with swinging handles 15 Mistake.
