Description
Technical field
This utility model relates to automobile exhaust silencing equipment parts technical field, is specially a kind of SCR dividing plate group die.
Background technology
The acoustic wave filter structure of existing band dividing plate typically uses and the dividing plate of inwall full contact type, i.e. selects the dividing plate mated completely with housing section, by dividing plate and housing interference fit, or completes the assembling of dividing plate and housing by the way of resistance welding.Because of dividing plate and the whole peripheral contact of housing, even if by interference fit or resistance welding mode, but owing to manufacturing factor or service wear, local location is still had to there will be the slight gap of elongate, the meeting turbulization when high-speed gas passes through gap by air-flow, and then produce ear-piercing howling, not only have impact on acoustic attenuation performance, and add the source of noise.Therefore, market is badly in need of a kind of diaphragm structure that can efficiently solve this problem of howling that slight gap between dividing plate and housing produces.And existing dividing plate occurs that the air inlet mouth of pipe is few and the mouth of pipe of giving vent to anger is few, it is unfavorable for air inlet and aerofluxus.
Utility model content
The purpose of this utility model is to provide a kind of SCR dividing plate group die, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model following technical scheme of offer: a kind of SCR dividing plate group die, including dividing plate one, dividing plate two, the air inlet mouth of pipe one, give vent to anger the mouth of pipe one, air dispelling hole one, the air inlet mouth of pipe two, give vent to anger the mouth of pipe two and air dispelling hole two, it is characterized in that: described dividing plate one upper end is provided with two air inlet mouths of pipe one, dividing plate one lower end is provided with two mouths of pipe one of giving vent to anger, it is provided with air dispelling hole one in the middle of dividing plate one, described dividing plate two upper end is provided with two air inlet mouths of pipe two, dividing plate two lower end is provided with two mouths of pipe two of giving vent to anger, it is provided with air dispelling hole two in the middle of dividing plate two, the described air inlet mouth of pipe one, give vent to anger the mouth of pipe one and air dispelling hole one is evenly distributed on dividing plate one, the described air inlet mouth of pipe two, give vent to anger the mouth of pipe two and air dispelling hole two is evenly distributed on dividing plate two.
Preferably, described dividing plate two edge has breach.
Preferably, described dividing plate two is provided with fabrication hole.
Preferably, described dividing plate one and dividing plate two all use cambered design, and thickness is 2.5mm.
Compared with prior art, the beneficial effects of the utility model are: this SCR dividing plate group die, by having breach at dividing plate two edge, ear-piercing howling is produced, it is ensured that excellent acoustic attenuation performance so that manufacture qualification rate higher when avoiding air by slight gap between dividing plate and housing, product quality is more stable, and the air inlet mouth of pipe is sufficient with the mouth of pipe of giving vent to anger, it is adaptable to the acoustic filter of all kinds of band dividing plates, and simple in construction, use reasonable in design and easy to spread.
