Description

Technical Field

[0001] The utility model relates to the field of muffler main shell molding devices, in particular to a muffler main shell molding device. Background Art

[0002] Muffler refers to a noise reduction device that can be used for air flow ducts with noise transmission, such as pipes and elbows with sound-absorbing linings or pipes with sudden changes in cross-sectional area and other discontinuous acoustic impedance, to attenuate or reflect the noise in the pipe. The former is called a resistive muffler, the latter is called a reactive muffler, and there are also impedance composite mufflers.

[0003] The main shell of the muffler can be processed into a tile shape or rolled into a pot shape. The shell of the pot-shaped muffler is formed by a round mandrel and the shell material is bitten or welded to be installed as a whole, and the welded parts are installed into the interface; the pot-shaped muffler is composed of an inner pipe, a turning elbow and an intermediate bottom plate, and then the outer bottom plate is connected to the shell by a groove or welding;

[0004] The main function of a muffler is to reduce the exhaust noise of the engine. This noise reduction effect is crucial for a variety of places, such as schools, hospitals and offices, because these places are usually sensitive to noise; through specific design and materials, the muffler effectively absorbs and reduces the noise generated by the engine exhaust, thereby ensuring that the impact on the surrounding environment and personnel is minimized; this not only improves the overall performance of the vehicle or equipment, but also provides users with a more comfortable and quiet working or driving environment.
