摘要:
The present invention relates to a cooking vessel comprising a vessel body (2) having a partially coated, textured stainless steel inner surface (3) having a plurality of ribs (10) rising above recesses (15) having bottoms (16) covered with a non-stick coating (7). The ribs (10) have uncoated tops (11) and sides (12) that are separate from the bottoms (16) of the cavities (15). The sides (12) connect the tops (11) to the bottoms (16). The tops (11) rise above the non-stick coating (7) covering the bottoms (16). According to the invention, the non-stick coating (7) rises over the sides (12) from the bottoms (16) towards the tops (11) without exceeding the height of the tops (11), and the bottoms (16) and the sides (12) have a rough surface (6) under the non-stick coating (7). The present invention also relates to a method for producing a cooking vessel.
摘要:
A method for fixing an additional bottom (4) to the external surface of the bottom (3) of a container (1), characterized in that the additional bottom and the container are mutually fixed by coining in a die with a male part (9) and a female part (8) which are connected to the footing and the moving slider of a press.
摘要:
A cutting device for cutting a metal bar into thin plate-like pieces, said cutting device comprising a supporting frame (1), which supports the metal bar (9) to be cut, and a cutter plate (2) substantially transverse to the metal bar for carrying out the cutting, said cutter plate comprising a straight and planar inner surface (3) oriented in a direction parallel to the cutting face at the end of the metal bar, an outer surface (4) on the side facing towards the piece (16) to be cut off, and a cutter (5) connecting the inner and outer surfaces and provided with a cutting edge (6). The cutting edge (6) of the cutter (5) is at a distance from the plane determined by the inner surface (3) towards the outer surface (4), so that there is between the inner surface and the cutting edge a connecting surface (7) deviating from the direction of the inner surface.
摘要:
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:
The invention is related to a method for joining two or more metal parts (1, 2) together. According to the invention, the joining is carried out by using roll forming techniques by placing the metal parts (1, 2) on top of each other on the form face (7) of a tool (4) which is made to rotate, and by arranging the topmost part (1) in linear roll contact with a forming tool (6) which is also in rotational movement, whereby the malleable deformation of the metal in the slot between the tools integrates the parts together. A mesh or perforated plate (2) of harder metal in particular can be joined to the sheet-like part (1) of a softer metal by using roll forming, by making the metal ingredient of the latter to penetrate the apertures (12) in the former. The invention can be applied in the manufacture of frying pans or other cooking vessels which are provided with induction-heated bottoms by joining, for example, a magnetic steel mesh or perforated plate to the bottom of a vessel made of aluminium, as part of the forming of an aluminium blank into the form of a vessel by using roll forming.
