Abstract
The utility model discloses an integrated type silencer, comprising a cylindrical shell with a pipe-shaped structure. Two clapboard silencing pipe subassemblies are distributed in the shell symmetrically; each clapboard silencing pipe subassembly consists of a clapboard and a silencing pipe; the end parts of the shell and end covers form an integrated type structure; and the end covers are in necking structures. In the integrated type silencer, the two end parts of the shell are processed in a spinning manner to be gradually reduced to a preset size, so that the end covers integrated with the shell are formed; and the same exhausting and denoising effects as the existing exhausting system are achieved, and simultaneously as the shell and the end covers are formed by spinning the two ends of one straight pipe, the material consumption is obviously reduced compared with that of the traditional split type part assembly. In addition, in the integrated type silencer, the process is simple, the cost is low, the quality is good, the industrial chain can be shortened, the time and the labor are saved, and the manufacturing cost is further reduced. The utility model is suitable for the silencers.
Description
Technical field
The utility model relates to silencing apparatus, particularly a kind of integral type silencing apparatus.
Background technique
At present, three grades of silencing apparatuss before, during and after automobile engine exhaust system generally includes are to reach better exhaust and to eliminate anti noise.Wherein, silencing apparatus is made up of parts such as housing, hush tube, dividing plate and end caps usually, and end cap adopts the seaming form to be connected with intermediate suppressor case, so the manufacturing process complexity expends time in and manpower the manufacture cost height; And, because end cap and housing are two single parts, cause total stock utilization not high, total specific consumption is bigger, and seaming also has the risk of gas leakage later on.
Summary of the invention
The purpose of this utility model is to provide the integral type that a kind of technology is simple, with low cost and tightness is good silencing apparatus at above-mentioned deficiency, with the purpose that realizes enhancing productivity and reducing cost.
In order to realize above purpose, a kind of integral type silencing apparatus that the utility model provides, the housing that comprises cylindrical tubular structure, symmetric arrangement has two dividing plate hush tube sub-assemblys in this housing, described dividing plate hush tube sub-assembly is made up of dividing plate and hush tube, the end of described housing and end cap are integral structure, and described end cap is a throat structure.
Described end cap is a small cylindrical tubulose structure, is connected by the arc surface transition between this small cylindrical tubulose structure and the housing, like this, forms monolithic construction by the arc surface transition between described end cap and the housing, and technology is simple and tightness good.
Described dividing plate is provided with the dividing plate hole, and the diameter in this dividing plate hole is 4～6mm, arranges according to noise requirements in this dividing plate hole, and it is better to reduce noise effects like this.
Described housing is provided with the technology groove that is used to locate, to prevent its rotation.
It is thin that described hush tube is provided with card, and this card carefully has the effect of regulating back pressure and reducing noise.
Described hush tube is provided with aperture, and this aperture is arranged according to noise requirements, and it is better to reduce noise effects like this.
The utility model is contracted to predetermined size gradually by the two end part spinning with housing, thereby form the end cap that is structure as a whole with housing, when reaching the exhaust same, eliminated noise effect with existing vent systems, because housing and end cap adopt a straight tube two ends spinning to form, so than traditional split type part assembled material consumption obvious reduction is arranged; In addition, this silencing apparatus technology is simple, with low cost and quality is good, can shorten industrial chain, save time and manpower, further reduces manufacture cost; Again on the one hand, because housing and end cap are monolithic construction, so its tightness is better.
The utlity model has characteristics such as simple, the with low cost and tightness of technology is good.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the cross-sectional view of Fig. 1.
Fig. 3 is the structural representation of dividing plate hush tube sub-assembly.
Fig. 4 is the structural representation of dividing plate.
Among the figure: 1-housing, 1a-technology groove, 2-dividing plate, 2a-dividing plate hole, 3-hush tube, 3a-card are thin, 3b-aperture, 4-end cap, 5-cambered surface.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment: as shown in Figure 1, a kind of integral type silencing apparatus, the housing 1 that comprises cylindrical tubular structure, symmetric arrangement has two dividing plate hush tube sub-assemblys in this housing 1, described dividing plate hush tube sub-assembly is made up of dividing plate 2 and hush tube 3, described dividing plate 2 is sleeved on described hush tube 3 inner ends, and the two end part of described housing 1 correspondence respectively are integral structure with end cap 4, and described end cap 4 is a throat structure.This end cap 4 is a small cylindrical tubulose structure, is connected (referring to Fig. 2) by arc surface 5 transition between this small cylindrical tubulose structure and the housing 1.
As shown in Figure 4, described dividing plate 2 is provided with the dividing plate hole 2a that arranges according to noise requirements, and the diameter of this dividing plate hole 2a is 5mm.Described housing 1 is provided with the technology groove 1a (referring to Fig. 1) that is used to locate.
As shown in Figure 3, described hush tube 3 is provided with the thin 3a of card.Described hush tube 3 is provided with the aperture 3b that arranges according to noise requirements.
When the utility model is produced, at first hush tube 3 and dividing plate 2 are assembled formation dividing plate hush tube sub-assembly in advance; And then two dividing plate hush tube sub-assemblys are pressed into respectively in the housing 1, and housing 1 two ends spinning formed arc surface 5 and end cap 4 (before the blanking, earlier the excess stock at cambered surface 5 and end cap 4 places is removed), and guarantee that the outer end of hush tube 3 and the end cap 4 of housing fit tightly.This silencing apparatus is connected between back level silencing apparatus and the prime silencing apparatus, cooperatively interact, when reaching the exhaust same, eliminated noise effect with existing vent systems, because housing and end cap adopt a straight tube two ends spinning to form, so than traditional split type part assembled material consumption obvious reduction is arranged; In addition, this silencing apparatus technology is simple, with low cost and quality is good, can shorten industrial chain, save time and manpower, further reduces manufacture cost; Again on the one hand, because housing and end cap are monolithic construction, so its tightness is better.
