The technical field to which the invention relates.
This invention relates to a cell stainless steel panels used for exterior or interior finishing works in construction of buildings, as well as to a method and apparatus for its production, while the panel is made from a pair of stainless steel plates and the honeycomb structure is inserted between them and connected by soldering, has increased strength and durability.
The level of technology
Currently, the panels used for exterior or interior finishing works for construction of buildings of medium or large size, are made of aluminum or stainless steel.
In the case of a honeycomb of aluminum, they are made of aluminum honeycomb structure is inserted between two aluminum plates and strongly connected with them with glue. As in the case of honeycomb aluminum honeycomb aluminum structure and exterior of the aluminum plate are connected to each other by glue, it makes it easier to manufacture, but are so constructed panel, particularly when used for exterior finishing work, under the influence of the external environment for a long time, suffer from oxidation of the adhesive, while the cracks, though very small, arise is when twisting or bending of the material depending on the needs, greatly reduce their longevity.
Aluminum has a low resistance to salts and, thus, the honeycomb aluminium panels can be less durable when used on the sea coast.
To eliminate these disadvantages, use cell panel of stainless steel which is more durable and wear resistant than aluminum, but in this case, use the same method of manufacture as in the case of honeycomb aluminium, i.e. use glue to connect the honeycomb structure made of stainless steel and stainless steel plates, and on the surface of stainless steel form the passive coating or membrane of iron and chromium, significantly deteriorating the bonding that often leads to delamination under the influence of the external environment.
For this reason, some existing cell stainless steel panels are made from a pair of stainless steel plates and aluminum honeycomb structure, which is inserted between the plates and stick them with glue, but the strength of the panels is not as high as desirable, because the bonding of two heterogeneous materials is unlikely to be perfect.
The basis for this invention is the task of solving the problems inherent in existing cellular panels of aluminum iliatova the stainless steel panels by making honeycomb panel, stainless steel, a material more durable and more durable than aluminum, namely by preparing plates of stainless steel; subsequent installation on the plate of sheet solder-coated flux on both surfaces; the location of the cellular structure of the stainless steel on the specified sheet solder; another sheet of solder, also covered with flux on both surfaces, the above mentioned honeycomb structure; the location of the other plate, stainless steel top of the whole structure; and, finally, the compression of the top and bottom of the whole stack in the press; and soldering by heating the entire structure, preferably at a temperature of 200°C-300°through the inclusion of heaters located inside the press.
This invention solves problems, in particular, exfoliation, inherent in the use of adhesives in the manufacture of honeycomb panels stainless steel, through the introduction of both sheets of solder covered with flux, for subsequent soldering heat.

The preferred embodiment of the invention
Below is a detailed description of the preferred exemplary embodiment of the invention, namely cell stainless steel panels, and method and device for its production, with reference to the drawings.
In the manufacture of honeycomb stainless steel according to this invention the two plates 2, 2' stainless steel feature, as shown in figure 1, opposite each other and between these two plates 2, 2' stainless steel insert cell structure 3, and thereby form a honeycomb panel 1 made of stainless steel.
Then, as shown in figure 2, between the honeycomb structure 3 stainless steel covered arc 91 and plate 2 stainless steel solder paste 5, covered on both surfaces also flux 91. Then, as shown in IG, plate 2 made of stainless steel with the solder 5, is covered with a flux 91 on both surfaces, on the lower side, and the other plate 2' stainless steel, has a different solder 5', also covered with flux 91 on both surfaces, on the upper side, a solder 5, 5' opposite each other, and then the honeycomb structure 3 stainless steel covered arc 91 on both contact surfaces is inserted between two stainless steel plates in contact with the upper solder 5 and the bottom solder 5'; next, a honeycomb structure made of stainless steel shrink and solder the heating plates 2, 2' stainless steel.
The solder 5, is covered with a flux 91, most preferably in the form of a sheet.
Thus, the plates 2, 2' stainless steel is placed on the outside, and a honeycomb structure 3 stainless steel insert between the plates 2, 2' located intermediate the solder 5, 5'; the connection of the cellular structure 3 stainless steel plates 2, 2' stainless steel comply with sheets of solder 5, 5', covered on both surfaces with flux 91. The bond of each wall 4 of each of the holes of the honeycomb structure 3 with the adjacent walls of the carry out using the usual well-known adhesives or spot welding.
When this bond the honeycomb structure 3 stainless steel plates 2, 2' of stainless steel is blowing steel should be firmly with sheets of solder 5, 5'covered with flux 91, while the binding of each of the contact wall 4 of each hole honeycomb structure made of stainless steel with adjacent walls must be strong enough to prevent their separation.
Since the cellular structure 3 stainless steel firmly in place during melting and solidification of the solder 5 and the flux 91, the wall of each hole honeycomb structure may be bonded to each other with sufficient strength to retain their shape.
Plates 2, 2' stainless steel and honeycomb structure 3 stainless steel according to this invention is fastened by soldering using a flux 91 and solder 5 in the form of a sheet at a low temperature, and therefore, the delamination cannot occur under any external conditions, and because binding occurs at low temperature, on the outer surfaces of the plates are no signs or traces of fasteners, spoiling the appearance of the panels.
For the implementation of the method of manufacturing a honeycomb 1 stainless steel according to this invention begins, as shown in figure 4 and figure 5 on the graphic, with the filing (stage S1) stainless steel plates, cut to the appropriate size, followed by floor (stage S2) of these plates 2, 2' flux 91 on their inner sides.
Then (stage S3) on plate 2, 2' from the stainless steel column steel was placed a sheet of solder 5, 5', covered on both surfaces with flux.
Then the plate 2 stainless steel located underneath the sheet of solder 5, is covered with a flux 91 on both surfaces, and the plate 2' stainless steel above her sheet solder 5', also covered with flux 91 on both surfaces, is placed within the press 6 so that the solder sheets 5, 5' come in contact with them (stage S4).
A honeycomb structure 3 stainless steel is inserted between the two plates 2, 2' stainless steel with intermediate spaced two sheets of solder 5, 5' (stage S5).
The two plates 2, 2' stainless steel and honeycomb structure 3 stainless steel grip and fasten soldering temperature, preferably at a temperature of 200°C-300°using heaters 7, 7', established in press 6 (stage S6).
In this case, the flux 91 may be caused to or on the inner surface of the plates 2, 2' stainless steel or both contact surfaces of the honeycomb structure 3 made of stainless steel, or on both surfaces of two sheets of solder 5, 5'. Any way, provided that the flux 91 is applied between the two plates 2, 2' stainless steel, solder sheets 5, 5' and the cellular structure 3 made of stainless steel.
