Method for manufacturing exhaust gas ducting device

摘要

A method for manufacturing exhaust gas ducting devices provides each device with an outer housing having an insert clamped therein, wherein the insert comprises a substrate traversed by exhaust gas, and an elastic compensating element surrounding the substrate. The method includes spreading each individual compensating element on a base and deforming the compensating element substantially vertical to the base by exerting a pressure such that the entire compensating element is subjected to a full-surface load. Then a setpoint deformation of the compensating element is determined, which is necessary to achieve a specified setpoint pressure. The method further includes determining at least one parameter of the substrate individually, placing the compensating element around the substrate, and mounting the insert thus obtained in an outer housing having inside dimensions that correspond to outside dimensions of the insert with the determined setpoint deformation.

1. A method for manufacturing exhaust gas ducting devices, in particular exhaust gas cleaning devices, which each have an outer housing with an insert clamped therein, wherein the insert comprises a substrate traversed by exhaust gas, and an elastic compensating element surrounding the substrate, including the following steps:
a) spreading each individual compensating element on a base separately from the substrate and deforming each compensating element substantially vertical to the base by exerting a pressure, wherein the entire compensating element is subjected to a full-surface load, b) determining a setpoint deformation of the compensating element necessary to achieve a specified setpoint pressure based on the pressure and associated deformation from step a), c) determining at least one parameter of the substrate individually, d) placing the compensating element around the substrate subsequent to deforming the compensating element, and e) mounting the insert thus obtained in the outer housing having inside dimensions that correspond to outside dimensions of the insert with the determined setpoint deformation.
