PROCEDE DE TRAVAIL A CHAUD, POUR COUPER, PERFORER ETC, DES MATERIAUX
OU METAUX DURS, DE NATURE QUELCONQUE.
L'objet de l'invention consiste en un procédé de travail grâ- ce auquel il est possible de perforer ou de tailler de fagon quelconque à chaud des métaux, même ceux qui, eu égard à leur compacité et leur na- ture particulières, sont considérés comme ne pouvant pas être sectionnés, même en utilisant les procédés thermiques les plus efficaces et les plus adéquats, actuellement en usage.
L'invention se base sur l'effet moléculaire provoqué, dans la structure interne de la matière soumise à la taille où à la perforation, par le fer ou autre matériau ferreux lancé sous pression.
Suivant la présente invention, en même temps qu'elle est soumise à l'action de la flamme chauffante-par exemple oxhydrique, oxya- cétylénique, etc- la pièce à sectionner est bombardée par des particules incandescentes du matériau ferreux réduit à l'état liquide par la même flam- me.
En pratique la mise en oeuvre de cette invention s'effectue en amenant une baguette du matériau ou composé ferreux-par exemple fer, acier, etc.- entre le bec de sortie du produit inflammable et le corps à tailler ou perforer, d'une manière similaire à celle déjà en usage pour la soudure autogène, oxyacétylénique, etc. Le jet de flamme, pro- duit par l'allumage du produit inflammable sortant sous pression du bec, attaque d'abord la baguette susdite de manière à la liquéfier petit à petit et ensuite à lancer violemment les particules produites, ainsi ren- dues incadescentes, contre le corps à sectionner ou tailler en vue de créer un vrai bombardement se joignant à l'action calorifique de la flamme.
Grâce au procédé de travail susdit, il est possible de tail- ler, forer ou de sectionner de n'importe quelle façon un matériau quel- conque qu'il soit de nature métallique ou non, comme par exemple la
<Desc/Clms Page number 2>
fonte, le bronze, la pierre, la brique, etc.
En adoptant la flamme oxhydrique ou oxyacétylénique, comme élément chauffant, on aura, grâce à l'opération susdite, des résultats décisifs, même pour des épaisseurs importantes, si on maintient la pression de travail du mélange inflammable légèrement supérieure à celle actuellement adoptée pour le sectionnement de matériaux moins durs.
L'application pratique de cette invention ne comporte pas l'emploi de chalumeaux ou becs spéciaux; en ce qui concerne le mélange du produit inflammable ou le réglage du jet de flamme, ceux qui sont habituellement prévus pour la soudure à flamme oxhydrique, oxyacétylé- nique, etc. sont suffisants.
REVENDICATIONS.
1. Procédé de travail à chaud,avec production de métal en fusion, pour couper, perforer ou sectionner de n'importe quelle façon en profondeur des matériaux ou métaux durs, de nature quelconque,- caracté- risé en ce que l'opération s'effectue à température élevée, obtenue grâce à un chalumeau ordinaire à découper, susceptible de brûler divers mélan- ges inflammables- oxhydrique, oxyacétylénique etc- et fortement comprimés, avec production simultanée de métal en fusion en vue d'effectuer un bom- bardement de particules de métal en fusion sur l'objet à couper, forer ou sectionner de manière quelconque, déjà porté au rouge par la même flamme chauffante.

HOT WORKING PROCESS FOR CUTTING, PERFORATING ETC, MATERIALS
OR HARD METALS OF ANY NATURE.
The object of the invention consists of a working process by means of which it is possible to perforate or cut in any way hot metals, even those which, having regard to their particular compactness and nature, are considered not to be severable, even using the most efficient and adequate thermal processes currently in use.
The invention is based on the molecular effect caused, in the internal structure of the material subjected to the size or to the perforation, by iron or other ferrous material launched under pressure.
According to the present invention, at the same time that it is subjected to the action of the heating flame - for example oxyhydrogen, oxy-ketylene, etc. - the part to be cut is bombarded by incandescent particles of the ferrous material reduced to the state. liquid by the same flame.
In practice, the implementation of this invention is effected by bringing a rod of the ferrous material or compound - for example iron, steel, etc. - between the outlet of the flammable product and the body to be cut or perforated, with a similar way to that already in use for autogenous, oxyacetylene welding, etc. The jet of flame, produced by the ignition of the flammable product exiting under pressure from the nozzle, first attacks the aforesaid rod so as to liquefy it little by little and then violently launch the particles produced, thus rendered incadescent. , against the body to be sectioned or cut in order to create a real bombardment joining the calorific action of the flame.
Thanks to the aforementioned working method, it is possible to cut, drill or cut in any way any material whether metallic or not, such as for example
<Desc / Clms Page number 2>
cast iron, bronze, stone, brick, etc.
By adopting the oxyhydrogen or oxy-acetylene flame as a heating element, thanks to the aforementioned operation, we will have decisive results, even for large thicknesses, if we maintain the working pressure of the flammable mixture slightly higher than that currently adopted for the sectioning of less hard materials.
The practical application of this invention does not involve the use of special torches or nozzles; as regards the mixture of the flammable product or the adjustment of the flame jet, those which are usually provided for welding with oxyhydrogen, oxyacetylene, etc. are sufficient.
CLAIMS.
1. Hot working process, with production of molten metal, for cutting, perforating or severing in any way in depth hard materials or metals of any kind, - characterized in that the operation s 'carried out at high temperature, obtained with an ordinary cutting torch, capable of burning various flammable mixtures - oxyhydrogen, oxyacetylene etc- and strongly compressed, with simultaneous production of molten metal in order to carry out a bombardment of particles of molten metal on the object to be cut, drilled or sectioned in any way, already heated to red by the same heating flame.
