Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, by the following examples, it and ties
Attached drawing is closed, the present invention will be further described in detail.It should be appreciated that embodiment described herein is only to understand this
Utility model does not limit the utility model.
With reference to Fig. 1-Fig. 3, one embodiment of the utility model provides a kind of muffler, including cylinder, cylinder both ends diameter
The connecting tube at both ends is formed to convergence, air inlet pipe of one end connecting tube as muffler, other end connecting tube is as muffler
Escape pipe, and inserted joint casing is distinguished in air inlet pipe and an air outlet pipe, one end of each casing is designed with expanding step, expanding step
Outer wall and the inner wall of corresponding side connecting tube fit, each casing in addition to expanding step part, the outer wall at remaining position with
There are gaps for the inner wall of corresponding side connecting tube, are welded and fixed between air inlet pipe and an air outlet pipe and corresponding casing.
As shown in Figure 1, the cylinder 1 of muffler is an integral molding structure, the both ends diameter of cylinder 1 gradually tapers up to be formed accordingly
The connecting tube of side, air inlet pipe and an air outlet pipe of the connecting tube at both ends respectively as muffler, the air inlet pipe and an air outlet pipe of muffler
For connecting other exterior lines.
Referring to figs. 2 and 3, one end of casing 2 is equipped with expanding step 20, the outer diameter of expanding step 20 be greater than casing 2 other
The outer diameter at position, when casing 2 is plugged in muffler corresponding side connecting tube, 20 one end of expanding step of casing 2 is towards cylinder 1
Inside, expanding step outer wall 23 connect the fitting of inside pipe wall 11 with corresponding side, can prevent phase between the insertion end of casing 2 and connecting tube
To shaking or dislocation, while also meeting the outer wall 22 at 2 other positions of casing and the inner wall 11 of connecting tube there are gap, use is such
Fit system is welded and fixed with corresponding side connecting tube for casing and prepares.
As shown in figure 3, in the present embodiment, expanding step 20 is that casing 2 thickens section, is integrally formed knot with casing 2
Structure, in other embodiments, expanding step 20 is also possible to 2 flange of casing or expanding end is formed.
As another embodiment, expanding step 20 and casing 2 are non-integral molding structure, and expanding step 20 is annular
And there is certain wall thickness, expanding step 20 is weldingly fixed on around the home on the outer wall of casing 2, and is set to one end of casing 2, together
Sample, which meets expanding step outer wall 23 and connect inside pipe wall 11 with corresponding side, to fit, the outer wall 22 and corresponding side at 2 other positions of casing
There are gaps for the inner wall 11 of connecting tube.
Specifically, in the present embodiment, expanding step 20 should have certain axial length, to guarantee locating effect.
Further, when casing 2 is plugged on cylinder 1, copper sheathing pressure-mounting tooling can be used to install, copper sheathing pressure-mounting work tool
There is groove compatible with 2 profile of casing, casing 2 is partially disposed in recessed grain, and the partial-length being placed in groove is to cover
Pipe 2 exposes the length of cylinder 1, and one end of copper sheathing pressure-mounting tooling can offset with the connecting tube of 1 end of cylinder when installation, at this time by copper
Set press-fitting tool is separated with casing 2, and the depth that casing 2 is inserted into cylinder 1 is realized controllable, prevents from being inserted into too deep and shadow because of casing 2
Ring the erasure effect and quality of muffler.
It is worth noting that the use of this copper sheathing pressure-mounting tooling being to realize that casing 2 is inserted into a kind of side that depth is controllable in cylinder 1
Formula is not specifically to limit, and other modes installation casing 2 can also be used, need to only meet casing 2 and be inserted into the depth of cylinder 1 not
Influence the quality and erasure effect of muffler.
As shown in Fig. 2, the connecting tube at muffler both ends is machined to form chamfering 12, the chamfering of corresponding side in inner edge
Stacked solder area is formed between 12 and the outer wall 22 of casing 2, the stacked solder area of formation is used to that solder is arranged, and is used for subsequent casings
With the welding of corresponding side connecting tube.
Specifically, in the present embodiment, for solder ring 3, solder ring 3 is set in stacked solder area the solder used, and
Be set on the outer wall 22 of casing 2, when muffler, which is placed in brazier, to be welded, solder ring 3 fusing fill up connection inside pipe wall with
The fixation between muffler connecting tube and corresponding side casing is completed in gap between corresponding side sleeve outer wall.
As shown in figure 3, the inner wall of casing 2 is additionally provided with stopper protrusion 21, stopper protrusion 21 and expanding step 20 are placed in casing 2
It is ipsilateral, when exterior line is plugged on 2 inside of casing, stopper protrusion 21 and the end of exterior line offset, outer for limiting
The insertion depth of portion's pipeline prevents the erasure effect that muffler is influenced due to exterior line is inserted into too deep.
Specifically, stopper protrusion 21 is ring structure, it is arranged at the inner wall of casing 2.
In the present embodiment, 1 material of cylinder is stainless steel, and the material of casing 2 is copper.
