Description
Technical field
The present invention relates to pipeline enlarging technical field more particularly to a kind of bellmouth systems for silencer.
Background technique
Automotive muffler, is mainly used for the noise generated when reducing the engine operation of motor vehicle, and principle is automobile row
Tracheae is made of two different pipelines of length, the two pipelines first separate to cross again, due to the length difference of the two pipelines
The half of the wavelength of the sound wave issued equal to automobile is cancelled out each other and decrease sound so that two column sound waves are interfered in superposition
By force, reduce the sound for being transmitted through, to play the effect of noise reduction.Silencer internal arrangement the metal sound insulation of many meshes
Disk makes column airflow diversion by multichannel, then mutually impacted by each point of air-flow, makes when exhaust gas enters silencer from exhaust main
Air-flow velocity slows down, and by multiple such process, reaches exhaust gas and is slowly flowed out by exhaust pipe, slow down exhaust gas pressure to reach
Power achievees the purpose that noise reduction.
Due to the designing points of silencer, the exhaust pipe in silencer is that middle section bending, a both ends have different length
The tubular member of flaring has the capping positioned at end in the vertical direction of tracheae setting.Have in capping and is docked with exhaust pipe
Lid mouth, in order to guarantee the sealed connection of silencer, the design bore for covering mouth is less than the nozzle of exhaust pipe, and bore is inconsistent resonable
By the effective use that above ensure that silencer.
The flaring forming technique of metal tube mostly uses oil pressure punch forming process at present, is flared at the both ends of processing exhaust pipe
When structure, first tubular member lower end is placed on the work top of enlarging apparatus, upper mold is controlled by oil pressure unit and processes cast
The flaring of part upper end overturns tubular member after processing one end flaring, and replaces upper mold, expands again by the oil pressure unit processing other end
Mouthful.The equipment needs to be flared in two times and more mold exchange, and cumbersome, production efficiency is lower, and equipment work top is without radial direction
Positioning, twice processing easily lead to product two ends flaring decentraction.
The inconsistent offset being easy to cause in installation process of silencer nozzle bore, due to having the hidden danger of installation offset
In the presence of, therefore the inlet and outlet relative position of exhaust gas after installing just not can guarantee, and the position can not also be installed after examine
It tests, only can just discover whether problematic after automobile actual use, be overhauled again after discovery, not only reduce the whole of automobile
Weight, but also the driving experience of driver is deteriorated.
Summary of the invention
