Embodiment Construction

[0031] figure 1 A honeycomb body 1 is shown, which has a casing 2 and a honeycomb structure 3 . The honeycomb structure 3 consists of sheet metal layers 4 which are at least partially structured so as to form a volume for a fluid to flow through. For the sake of clarity, the structure of the sheet metal layer 4 has been omitted in the figure. A measuring sensor 5 fastened in a flange part 6 is mounted in the honeycomb body 1 . This flange part 6 is connected to the hole rim 7 of a hole 16 formed in the bushing 2 . The honeycomb structure 3 has a volume 11 without the sheet metal layer 4 for receiving the measuring sensor 5 .

[0032] This empty volume 11 can be produced in different ways and methods, for example holes can be made before or even after stacking or winding by known cutting / separating techniques such as sinker etching (Sinkerodieren), laser cutting, water jet / high pressure water cutting Wait to make. In addition, it is also possible to separate / cut apart at l...

Abstract

Method for producing a honeycomb body (1) with a honeycomb structure (3), a sleeve (2) and a flange part (6) for a measuring sensor (5) on the sleeve, the The method comprises the following steps: manufacturing the casing (2) from a sheet metal; making a hole (12) in the sheet metal at a predetermined position with a hole edge (7) as the edge; installing the flange (6) on the hole edge (7) in the casing (2); put the honeycomb structure (3) into the casing (2); and carry out a common heat treatment process so that the casing (2) and the honeycomb structure (3) Connect with flange (6). The connection of the flange part ( 6 ) to the sleeve ( 2 ) can advantageously be integrated into an already existing heat treatment process, which makes production simple and fast and thus reduces costs.

Description

technical field [0001] The invention relates to a method for producing a honeycomb body with a honeycomb structure, sleeves and a flange part for a measuring sensor, and also to a method for producing a honeycomb body with a flange part for a measuring sensor honeycomb body. Background technique [0002] In vehicle construction, honeycomb bodies are frequently used as catalyst substrates within the framework of devices for the catalytic conversion of combustion exhaust gases of internal combustion engines. In the range of increasingly strict legal limit values ​​for the permissible concentrations of pollutants in the exhaust gases of internal combustion engines emitted into the environment, it is necessary to use exhaust gas purification systems whose performance is adapted, for example, to the composition of the exhaust gases. This is usually achieved by means of a regulated exhaust gas purification system with a measuring sensor in the area of, for example, the catalyst s...
