Abstract
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.
Claims26
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.
A method for manufacturing exhaust gas cleaning devices including a housing and a gas-traversed insert clamped in the housing comprising the following steps:
- heating the housing in a machine tool;
- plastically deforming the heated housing in the machine tool;
- arranging the gas-traversed insert in the heated housing;
- and
- wherein said method is a calibration method comprising the following method steps:
- wrapping the gas-traversed insert with an insulation mat to provide a wrapped insert;
- heating the housing in the machine tool to provide a heated housing;
- arranging the wrapped insert in the heated housing;
- and
- plastically deforming the heated housing in the machine tool by reducing outside dimensions of the housing.
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. wrapping the gas-traversed insert with an insulation mat to form a wrapped insert;
- b. staring to heat the housing in a machine tool to increase the temperature of the housing;
- and
- c. arranging the wrapped insert in the heated housing while the housing is heated in the machine tool.
