Description

COUPLED ANTI-CUT MATERIAL AND PRODUCTS OBTAINED
Technical field
The invention relates to an anti-cut coupled material for the production of anti-cut products in general, such as bolts, hinges, hinges, and harpoons, walls of safes and armored walls, locks for doors and windows of houses or commercial premises, capable of withstanding attempted break-ins carried out, for example, with flexible and similar cutting tools.
State of the art
Currently, there are a wide variety of anti-cut materials known and available on the market.
In the case of locks for locks, they are normally made up of steel bars operated by a lock fixed to a door or window leaf to engage and disengage a counter plate on command and thus lock the door or window.
The materials of the known type are generally satisfactory for ease of use and availability, but have various disadvantages regarding their security against break-ins carried out with cutting tools.
In particular, it has been found that steel bars, although made of the best alloy, can hardly withstand the cutting action of rotating tools such as cutting discs of a flexible.
There is therefore a need to be able to have an anti-cut material that improves the ability of the lock to resist break-in attempts by cutting.
Aim of the invention
With this invention, it is intended to overcome the disadvantages of the already known solutions and to propose a method for producing bolts capable of obtaining products with improved mechanical characteristics, particularly anti-cut and at low production cost.
Summary of the invention
These purposes have been achieved by means of a material according to at least one of the attached claims.
A first advantage is that with the material of the invention, it is possible to produce bolts, anti-cut walls, door hinges, locking systems in general with high resistance to cutting. A second advantage of the invention is that the products obtained with the material can be produced with easily available technologies and with materials at a relatively limited cost compared to the anti-break-in performances offered.
List of drawings
These and other advantages will be better understood by those skilled in the art from the following description and the accompanying drawings, given as a non-limiting example, in which:
Fig.1 schematically shows a lock equipped with a bolt produced with the material of the invention;
Fig.2 schematically shows the stages of a method of the invention;
Fig.3 shows a bolt produced with the material of the invention; Fig.4 shows a second embodiment of a bolt core according to the invention;
Figs.5a, 5b, 5c respectively show an anti-cut wall according to the invention in an exploded view before production, in a box form for its production, and in a sectional view once produced.
Detailed description
With reference to the accompanying drawings, an anti-cut coupled material is described, comprising a resistant body 1 made of a material with high wear resistance, chosen for example from ceramic materials such as alumina, boron carbide or silicon carbide, stably coupled with an external metal foil 2 preferably made of steel, aluminum or brass.
In the context of the present invention, stably coupled should be understood as a coupling between body 1 and foil 2 for which even after the cutting of the metal foil, for example in an attempted break-in, the ceramic body remains applied to the foil, and this also in the event of a breakage of the ceramic body.
According to the invention, it has been found that ceramic material, when subjected to the action of a tool capable of cutting metal, is capable of resisting tool erosion due to its high hardness. In the event of breakage, the ceramic material fractures along different and discontinuous fracture lines compared to the line of action of the cutting tool, such as a blade or a disk.
For example, a suitable ceramic material for use is a ceramic material with a Vickers hardness greater than 1500 and up to about 2500 Vickers in the case of boron carbide. Consequently, the coupled material will not be cut, except by tools capable of cutting ceramic material, as long as the ceramic body 1 and the metal blade 2 maintain their coupling.
In a first embodiment, the resistant body is formed by a core precisely and stably contained within a metal sheath or casing, and the coupling is maintained stable by the geometric containment of the ceramic body within the metal blade.
In figures 1 , 3, and 4, an exemplary application is shown in which the material is used to produce a latch C for locks S in which the body is formed by a ceramic core, for example, cylindrical or parallelepipedal, and the metal blade is a sheath 2, for example, a sleeve of steel, aluminum, or brass, that covers and contains the ceramic body. In figure 4, the case is shown in which the core is formed by ceramic discs or sectors 5 placed inside the sheath.
In a second embodiment of the material, the resistant body is formed by a ceramic body stably coupled by gluing to said metal blade.
Figures 5a-5c show a preferred application of the material to obtain an anti-cutting wall P. Figure 6 shows a preferred embodiment in which anticutting locking pins 20 of a door 21 of a vault 22, such as a bank vault, are produced by the treatment of the invention.
In the example described, also schematically shown in figure 2, the wall P is obtained from a coupled material according to the invention subjected to the following stages:
F1 ) cleaning of the surface 3 of the body 1 and the coupling surface 4 of the blade 2, preferably by shot peening, sandblasting, or burnishing until any surface impurities are removed. Preferably, the cleaning stage is carried out by shot peening at sixteen Almen degrees, for example, by using four centrifugal rotators of 5 kw, and can be followed by a depolluting stage to remove any residues left by the cleaning stage. F2) coating the surface 3 of the body 1 and the coupling surface 4 of the blade 2 with a gripping agent, also called primer or glue;
F3) drying the body 1 and the blade 2 in the absence of humidity, preferably at a temperature between 15°C and 25°C;
F4) preheating the body 1 and the blade 2 until the surface viscosity of the gripping agent is reduced, heating at a temperature preferably between 50°C and 200°C to promote the subsequent bonding of a polymer compatible with the gripping agent, which in this stage is sticky to the touch.
F5) coupling the body to the blade with an intermediate thermosetting polymer layer 12 composed of a polymer with two or more components, of which at least one is compatible with said gripping agent.
It is specified that within the scope of this description, the polymer component compatible with the adhesive is intended to mean a component capable, in combination with the adhesive, of establishing an adhesive bond between the polymer and the coated surface of the adhesive.
F6) Hardening and complete activation of the bond between the polymer and the adhesive preferably by heating the coupled body and the intermediate polymer layer to a temperature preferably between 50 and 150 degrees Celsius, preferably 100°C.
Preferably, the coupling phase with the polymer can be carried out by pouring the polymer into a containment mold 10 of the plate until the gap 11 between the ceramic body 1 and the metal plate 2 is filled so that the polymer forms a binding layer P.
Preferably, the gap can be created by spacers 8 positioned between the ceramic body 1 and the metal plate 2 before insertion into the mold.
In further application examples, the intermediate polymer layer can be obtained, for example, by coating, immersion, or spraying of the polymer.
The invention has been described with reference to a preferred embodiment, but it is understood that equivalent modifications can be made without departing from the scope of protection granted.
