Manufacturing method of flanging press-fitting tool for metal heat shield of automobile catalytic converter

1. The utility model belongs to the technical field of automobile catalytic converters, and particularly relates to a flanging press-fitting tool for metal heat shields of automobile catalytic converters.

Background technique:

2. The automobile catalytic converter is the most important external purification device installed in the automobile exhaust system. It can convert harmful gases such as co, hc, and nox discharged from automobile exhaust into harmless carbon dioxide, water and carbon dioxide through oxidation and reduction. Nitrogen. Automobile catalytic converters will generate a lot of heat when they are working. If they are not insulated, it will affect the working conditions of other working parts of the automobile. Now automobile catalytic converters usually use metal heat shields for heat insulation.

3. However, in the existing metal heat shield production process, due to technical reasons, several vertical flanges will be left on the sealing seam of the metal heat shield. If it is not processed, it will affect the metal heat shield in the car. On the installation work. Usually the flanging is hammered manually with a hammer, and then the car is installed after being flattened. However, a metal heat shield construction worker usually needs to smash for about 20 minutes, which is labor intensive, slow in work speed, and low in work efficiency. The high cost of enterprises is not conducive to large-scale and large-scale production activities. In order to solve the above-mentioned problems, the utility model proposes a flanging press-fitting tool for the metal heat shield of the automobile catalytic converter.
