Method and machine tool for manufacturing exhaust gas cleaning devices

摘要

A machine tool for manufacturing exhaust gas cleaning devices, in particular diesel particulate filters and catalysts that have a housing and a gas-traversed insert clamped in the housing, comprises at least one tool, in which the insert is clamped in the housing. A heating device that heats the housing is integrated in the tool. In a method for manufacturing exhaust gas cleaning devices, the heated housing is plastically deformed in a machine tool, and the insert is inserted into the housing.

主权项

1. A method for manufacturing exhaust gas cleaning devices including a housing and a gas-traversed insert clamped in the housing comprising the following steps:
a. heating the housing in a machine tool; b. plastically deforming the heated housing in the machine tool; c. arranging the gas-traversed insert in the heated housing; and d. clamping an insulation mat including a binder between the gas-traversed insert and housing, wherein the temperature of the heated housing liquefies the binder in the insulation mat.
