Description
Technical field
The present invention relates to silencer production technical field, more particularly to a kind of support meanss for silencer pressure core.
Background technology
Automotive muffler, is mainly used in the noise produced during the engine work for reducing motor vehicle, and its principle is automobile row
Tracheae is made up of two different pipelines of length, and the two pipelines are first separated to cross again, due to the length difference of the two pipelines
The half of the wavelength of the sound wave sent equal to automobile so that two row sound waves are interfered in superposition and cancelled out each other and decrease sound
By force, reduce the sound for being transmitted through coming, so as to play the effect of noise reduction.Silencer internal arrangement the metal sound insulation of many meshes
Disk, when waste gas from exhaust main enters silencer, makes post airflow diversion by multichannel, then is mutually impacted by each point of air-flow, makes
Air-flow velocity slows down, and by multiple such process, reaches that waste gas is slowly flowed out by blast pipe, waste gas pressure is slowed down to reach
Power, reaches the purpose of noise reduction.
Due to the designing points of silencer, the blast pipe in silencer is that stage casing bending, a two ends have different length
There is the capping positioned at end in the tubular member of enlarging, the vertical direction set along tracheae.Have in capping and docked with blast pipe
Lid mouthful, in order to ensure being tightly connected for silencer, the design bore of lid mouth is less than the mouth of pipe of blast pipe, and bore is inconsistent resonable
By above ensure that silencer effectively use.
Silencer, due to producing impulse force to dividing plate during pressure core, can cause the deformation of dividing plate when carrying out pressure core technique,
Cause the percent defective of product high.
