Abstract

The invention relates to a process for manufacturing a muffler. The process has the advantages that: in right ceramic paper, edge lines of the right ceramic paper are determined to be 10mm far away from arched inner edge border lines of a right outer shell and a right inner shell inwards, and the right ceramic paper is cut in advance and placed between the right outer shell and the right inner shell for next welding; and in left ceramic paper, the edge lines of the left ceramic paper are determined to be 10mm far away from the arched inner edge border lines of a left outer shell and a left inner shell inwards, and the left ceramic paper is cut in advance and placed between the left outer shell and the left inner shell for the next welding. The process for manufacturing the muffler has the advantages of good sound insulation and heat insulation effect of the manufactured muffler, simplicity, and high accuracy.

Description

technical field [0001] The invention relates to a manufacturing process of a muffler, in particular to a manufacturing process of a double-pipe muffler. Background technique [0002] In the prior art, there are numerous mufflers, especially motorcycle mufflers. Most of the mufflers of conventional motorcycles have a single-layer structure, and most of the exhaust pipes connected to the muffler are also of a single-layer structure. [0003] The single-layer structure of the muffler assembly has many disadvantages, such as high noise, high surface temperature, easy to burn the user, and low mechanical strength. [0004] Another technical disadvantage of the prior art is that the right ceramic paper and the left ceramic paper are temporarily cut out compared to the outer shell when the right outer shell and the right inner shell are ready to be welded, or when the left outer shell and the left inner shell are ready to be welded. Low and inaccurate. Because the ceramic paper ...
