Silencer manufacturing method and silencer

Abstract

The invention relates to the technical field of silencers, in particular to a silencer manufacturing method and the silencer. The manufacturing method comprises the steps that a barrel-shaped silencershell body with an opening at one end is pulled out through a deep drawing and stretching integrated forming mode, wherein the shell body is provided with a cover part and a side part which are integrally formed, the cover part is located at one end of the shell body, and the side part is located on the circumferential side of the shell body; and one end, with the opening, of the shell body is arranged towards an inner audio assembly in the silencer, the shell body is correspondingly assembled at the two ends of the inner audio assembly. Therefore, compared with an original method in which the silencer is manufactured by carrying out welding and seam locking on a metal plate after the metal plate undergoes edge rolling, and then an edge cover is installed, the noise reduction function ofthe silencer is guaranteed, meanwhile, machining and mounting steps of the original part edge cover are reduced, and then the complex repetition of the part and the waste of materials are reduced; andmeanwhile, the barrel-shaped silencer shell body with the opening at one end is manufactured through the deep drawing and forming mode, so that the uniformity of the size of the part of the silenceris better, and the stability of the quality of the silencer is guaranteed.

Description

technical field [0001] The invention relates to the technical field of mufflers, in particular to a method for manufacturing a muffler and the muffler. Background technique [0002] At present, in the fields of generator sets, construction machinery, agricultural machinery, all-terrain vehicles, and garden tools, users have higher and higher requirements for the control of noise pollution and air pollution. For mufflers, their function and quality requirements are also increasing accordingly. [0003] Such as Figure 1 to Figure 4 As shown, the existing muffler mainly includes a housing 11, an inner sound pipe 13 accommodated in the housing 11, an inner sound plug 14 and a partition 12, which are arranged at both ends of the housing 11 for blocking the two ends of the housing 11. The side cover 16 at the end, and the air inlet pipe assembly 17 and the air outlet pipe assembly 18 installed on the inlet and outlet of the housing 11. [0004] In the manufacturing process of t...
