摘要:
The present invention relates to a method for manufacturing a formed piece of aluminium or some other relatively soft metal. In accordance with the invention, a slice is cut from a rod of aluminium or some other raw-cast metal; the slice forms a blank (3), which is placed on the mould surface (10) of a mould tool (5) rotating about its axis (4), and which is formed using a roll forming tool rotating about its axis (6) inclined to the axis of the mould tool and being in linear rolling contact with the blank surface. The blank is then formed to a substantially disc-shaped piece of plate between the opposite rotating tools (5, 7). The method may be part of the manufacturing process of a frying pan or kettle so that the roll formed piece may comprise the bottom and collar of the utensil, which is bent to form the sides of the cooking utensil at the next pressure turning stage; or, alternatively, the rol formed piece may be fastened as the bottom to a separately manufactured utensil by linear pressing. The formed piece may also be deep-drawn to a globe of a street light, or it may be used as a traffic sign, or as a lid for a soft-drink can.

Le procédé pour former un décor comprend les étapes suivantes:
a) on attaque chimiquement, au moins ladite face de l'ustensile (1) former sur celle-ci des microcavités (3) d'accrochage; b) on applique directement sur des zones prédéterminées de ladite face délimitant le décor (2), une composition à base de résine fluorocarbonée et d'un pigment coloré; c) on chauffe pour faire cuire la résine fluorocarbonée dudit décor; d) on applique sur ladite face, y compris ledit décor, une surface de pressage (4), avec une pression suffisante pour éliminer les microcavités (3) situées à l'extérieur des zones recouvertes par le décor (2) (voir figure 2).

L'article est constitué à partir d'une plaque réalisée en un premier métal (1) relativement mou. Il présente sur l'une de ses faces un élément métallique (2) sous forme de feuille ajourée ou de grille réalisé en un second métal ou alliage plus dur que celui de la plaque (1), ledit élément métallique (2) étant fixé sur ladite plaque par matriçage ou frappe pour l'encastrer au moins partiellement dans cette dernière. Application notamment pour des récipients culinaires.

The present invention relates to a method for obtaining an item of cookware, comprising the following steps of: - producing or providing a blank from a textured sheet of stainless steel having at least one textured face, - stamping the blank in order to form a cap (2) having an inner face (3) and an outer face (4), the outer face (4) having parts in relief corresponding to the textured face of the blank, - optionally, partially covering the outer face (4) of the cap (2), - carrying out a mechanical finishing treatment of the free surface of the outer face (4) of the cap (2) in order to expose the stainless steel at the parts in relief of the free surface of the outer face (4) of the cap (2). The present invention also relates to an item of cookware comprising a stamped cap (2) made of stainless steel having an inner face (3) and an outer face (4), wherein the outer face (4) of the cap (2) has a textured free surface (5).
摘要:
A tank comprising a vessel wall (11) and a bottom (12) fixed to said vessel wall (11). The bottom (12) comprises a portion (14) obtained by chip-removing machining. The tank can be used for a machine for kneading foodstuff substances in which the tank can be driven in rotation by driving means of driving said machine. The aforesaid portion (14) is prearranged for direct engagement with the aforesaid driving means of the kneading machine.

A process for the manufacture of cooking vessels, in particular pots and/or pans in a relatively soft metallic material, with a plate in a metallic material of high hardness applied to the bottom of the vessel, performs a stable connection among said parts with no mechanical and/or thermal trauma for the materials and comprises the steps of: providing a plate (1) provided with a plurality of points (6) projecting from a surface (4) thereof; inducing, by compression, the penetration of said points (6) and the adhering of said surface (4) at the bottom (20); and stretching said bottom (20), thereby causing the deformation and the clutching of said points (6).
摘要:
A process for the manufacture of cooking vessels such as pots or pans and the like allows to obtain an apparent and long-lasting coined bottom, invisible inside the vessel, and comprising the steps of providing a flat member (1) in a metallic material apt to be formed into a vessel (15); depositing one or more outer coating layers (4) on a first surface (2) of said flat member (1); coining said first surface (2) at one coining region (6) thereof housed in a bottom region (14) of the vessel (15) to be formed, determining recesses (7) of predetermined depth; depositing one or more inner coating layers (10) on the second surface (3); and removing, at said bottom region (14), a thickness of said first surface (2) with said one or more inner coating layers (4), lower than said predetermined depth.

Le procédé consiste à fixer par frappe sur la face (2) de la plaque (1) revêtue d'anti-adhésif une grille (3) ou une feuille ajourée en métal plus dur que l'aluminium de manière à encaster au moins partiellement ladite grille (3) ou feuille ajourée dans ladite face (2) de la plaque (1)
摘要:
Ce dispositif de fixation de pièces d'un appareil électroménager, dont l'une au moins est une pièce d'assemblage métallique (4) en forme de tôle ou de plaque comprend un élément d'assemblage et de sertissage (5) faisant saillie de l'une des faces de ladite pièce d'assemblage métallique (4) et dont la structure est issue de ladite pièce. La partie de ladite pièce d'assemblage métallique (4) formant ladite base dudit élément d'assemblage et de sertissage (5) s'étend jusqu'au niveau de l'autre face de ladite pièce d'assemblage métallique (4). Le volume de la partie saillante dudit élément d'assemblage et de sertissage (5) correspond sensiblement à celui d'un déplacement de matière (7), obtenu par réduction locale de l'épaisseur autour de la base et autour du côté de l'élément d'assemblage et de sertissage (5).
