Detailed description of the invention
First, after being furtherd investigate by the phenomenon crushed in encapsulation process to catalytic-converter substrate, inventor finds the special nature due to liner, and its pressure is process (as shown in Figure 1) over time.Within the originally short period of gasket compression, its pressure can sharply rise, and this pressure sharply risen can cause very large impact to catalytic-converter substrate, and the crushed accident of catalytic-converter substrate often occurs.
The present invention is just based on the technical scheme of the technical solution problem drawn after above-mentioned theory analysis.Due to the liner shown in Fig. 1 pressure performance with the time there is obvious relation, at liner by the initial stage compressed, the pressure of liner far away higher than the pressure that the liner normal service phase presents, so introduce the concept of carrier substitute in the present embodiment.By method of the present invention, pressure when allowing liner occur extreme value pressure acts on carrier substitute, after treating that relaxing appears in the pressure of liner, real catalytic-converter substrate is stuffed into again, setting like this, the surge pressure of liner can be avoided to be acted directly on catalytic-converter substrate by the very first time, also just reduce the crushed probability of catalytic-converter substrate.
