[0003] In the "Method and Device for Brazing Metal Honeycomb Body with Brazing Materials" published on July 27, 1994 with the application number 93107689.7, it was mentioned that the metal honeycomb body for motor vehicles was introduced in German patent DEA2302746 or DEA2924592 The method of welding with brazing materials has the disadvantages of requiring too much brazing material to make the method uneconomical, and secondly, alloying the plate with the brazing material to affect the characteristics of the plate; also mentioned some The method of welding with adhesives and brazing materials, which is more or less uneconomical or difficult to produce
The process is complicated and many special parts are required

Embodiment Construction
[0009] What the embodiment of the present invention will manufacture is as figure 1 The metal honeycomb carrier for motorcycles shown includes an outer cylinder 1, a flat sheet 2, and a corrugated sheet 3. The waveform of the corrugated sheet 3 can be sinusoidal or triangular. Such as figure 2 As shown, in this embodiment, corrugated sheet 3 is connected with flat sheet 2 by spot welding at 5 centimeters of flat sheet 2 incisions earlier, and the spot welding head of this spot welding machine has four, and each spot welding head has a The power supply is powered, and there are four welding points 4 in one welding. The number of spot welding heads depends on the width of the plates, and the purpose is that the two plates can be firmly connected. Insert the slit of the flat plate that has been welded with the corrugated sheet into the winding machine, which is installed on the frame of the spot welding machine. The flat sheet 2 is first overlapped and wound to form a core, an...

The present invention relates to the production process to a kind of metal honeycomb carrier for motorcycle to carry tail gas purifying catalyst. The producing process includes spot welding to connect corrugated sheet and plate sheet by using one spot welder with at least four spot welding heads and in the position 3-7 cm away from the cut of the plate sheet, winding while spot welding, slightly tightening the wound core, jacketing outer cylinder, and spot welding connecting at the two ends of core and at the contacts between core end and outer cylinder. The production process is simple and suitable for production in large scale.
Description
technical field [0001] The invention relates to a manufacturing method of a metal honeycomb carrier used for carrying a catalyst for purifying motorcycle exhaust gas. Background technique [0002] With the improvement of people's living standards, motorcycles are becoming more and more popular, and the direct discharge of its tail gas without purification is more and more serious to air pollution. For this reason, many cities have adopted restrictive measures to motorcycles, and the national environmental protection department will also issue strict policies to limit the discharge of motorcycle pollutants. The main measure to control motorcycle pollution is to install an exhaust catalytic converter, and the catalyst carrier is the main component of the exhaust catalytic converter. It can be ceramic or metal. A catalyst is coated on it to achieve carbon monoxide, Catalytic conversion of hydrocarbons and nitrogen oxides into carbon dioxide and water puri...
