Abstract
Description
La présente invention concerne une structure de tôles émaillées, ainsi qu'un procédé de fabrication d'une structure de tôles émaillées.The present invention relates to a structure of enamelled sheets, as well as a process for manufacturing a structure of enamelled sheets.
Elle concerne de manière générale le domaine technique de l'émaillage d'une structure en tôle comprenant une portion de raccordement dans laquelle deux tôles sont assemblées, par exemple par soudage.It generally concerns the technical field of the enamelling of a sheet metal structure comprising a connection portion in which two sheets are assembled, for example by welding.
Dans cette portion de raccordement, les tôles sont superposées bord contre bord.In this connection portion, the sheets are superimposed edge to edge.
Lors de l'émaillage d'une telle structure en tôle, l'émail en poudre, déposé par effet électrostatique, adhère parfaitement aux surfaces des tôles.When enamelling such a sheet structure, the powder enamel, deposited by electrostatic effect, adheres perfectly to the surfaces of the sheets.
En revanche, la poudre d'émail n'est presque pas déposée au niveau des angles et des tranches des bords des tôles.On the other hand, the enamel powder is hardly deposited at the level of the angles and edges of the edges of the sheets.
Après cuisson de l'émail, on observe la formation de parties agressives dans cette portion de raccordement, notamment au niveau des tranches des tôles.After baking the enamel, we observe the formation of parts aggressive in this connection portion, especially at the slices of the sheets.
En effet, les parties de tôle non recouvertes d'émail sont brûlées lors de la cuisson et présentent ensuite un aspect rugueux.Indeed, the parts of sheet metal not covered with enamel are burnt during cooking and then have a rough appearance.
La présente invention a pour but de résoudre l'inconvénient précité et de proposer une structure de tôles émaillées d'aspect parfaitement lisse après émaillage.The object of the present invention is to solve the drawback aforementioned and to propose a structure of enamelled sheets of aspect perfectly smooth after enameling.
La structure de tôles émaillées visée par l'invention comprend une portion de raccordement de deux tôles, les tôles étant superposées bord contre bord dans la portion de raccordement. The structure of enameled sheets targeted by the invention comprises a connection portion of two sheets, the sheets being superimposed edge against edge in the connection portion.
Conformément à l'invention, la portion de raccordement comporte un espace rempli d'émail entre les deux tôles, en regard de la tranche du bord d'une des deux tôles.According to the invention, the connection portion comprises a space filled with enamel between the two sheets, opposite the edge edge one of the two sheets.
Ainsi, les surfaces des deux tôles ne sont pas complètement jointives au niveau de la tranche du bord d'une des tôles.Thus, the surfaces of the two sheets are not completely joined at the edge edge of one of the sheets.
Au contraire, un espace rempli d'émail est prévu, permettant de former une réserve d'émail qui permet de recouvrir ainsi la tranche de cette tôle.On the contrary, a space filled with enamel is provided, allowing form a reserve of enamel which thus covers the edge of this sheet.
On évite ainsi, lors de la cuisson de l'émail, de brûler les tranches de tôle et on élimine par conséquent toute partie agressive dans la portion de raccordement de la structure de tôles émaillées.This avoids burning the slices when cooking the enamel of sheet metal and therefore eliminates any aggressive part in the portion of connection of the structure of enamelled sheets.
Selon une caractéristique préférée de l'invention, ledit espace est constitué d'un creux embouti dans une première tôle.According to a preferred characteristic of the invention, said space is consisting of a hollow stamped in a first sheet.
Ce creux formant une réserve d'émail, réalisé par emboutissage, permet de créer facilement un espace libre entre les deux tôles au niveau de la portion de raccordement.This hollow forming a reserve of enamel, produced by stamping, makes it easy to create a free space between the two sheets at the level of the connecting portion.
Selon une autre caractéristique préférée de l'invention, la tranche du bord de la seconde tôle est biseautée, l'extrémité de la tranche biseautée étant en regard dudit espace rempli d'émail.According to another preferred characteristic of the invention, the slice the edge of the second sheet is bevelled, the end of the beveled edge being opposite said space filled with enamel.
Par la formation d'un biseau, on favorise le dépôt d'émail sur la tranche du bord de la seconde tôle et on limite l'épaisseur de cette seconde tôle au niveau de l'espace rempli d'émail.By forming a bevel, the deposition of enamel on the edge edge of the second sheet and we limit the thickness of this second sheet at the level of the space filled with enamel.
L'extrémité biseautée de la seconde tôle peut ainsi être aisément noyée dans la réserve d'émail formée dans l'espace entre les deux tôles.The bevelled end of the second sheet can thus be easily embedded in the enamel reserve formed in the space between the two sheets.
Selon un autre aspect de l'invention, un procédé de fabrication d'une structure de tôles émaillées comprend les étapes suivantes :
- emboutissage d'un espace en creux dans une première tôle, parallèlement au bord de la première tôle ;
- fixation de la première tôle à une seconde tôle, les bords des deux tôles étant superposés et l'espace en creux de la première tôle s'étendant en regard de la tranche du bord de la seconde tôle ;
- dépôt d'une poudre d'émail de manière à former une réserve d'émail dans ledit espace en creux ; et
- cuisson de la poudre d'émail.
- stamping a hollow space in a first sheet, parallel to the edge of the first sheet;
- fixing the first sheet to a second sheet, the edges of the two sheets being superimposed and the hollow space of the first sheet extending opposite the edge of the edge of the second sheet;
- depositing an enamel powder so as to form a reserve of enamel in said hollow space; and
- baking the enamel powder.
Comme décrit précédemment, on réalise ainsi dans la portion de raccordement des tôles, une réserve d'émail qui permet de recouvrir la tranche du bord de la seconde tôle afin d'éliminer les brûlures de cette tranche et l'agressivité de la tôle après émaillage.As described above, in the portion of connection of the sheets, a reserve of enamel which covers the edge from the edge of the second sheet in order to eliminate burns from this section and the aggressiveness of the sheet after enamelling.
D'autres particularités et avantages de l'invention apparaítront encore dans la description ci-après.Other features and advantages of the invention will become apparent again in the description below.
