Abstract
This utility model relates to a kind of silencer muffler partition plate that can limit fusion length, belongs to a kind of automotive muffler partition plate.Including clapboard body, at dividing plate circular cross-esction, output the arc groove that width is 1mm, the arc length of this arc groove be with core sealing of tube at fusion length.Advantage is novel structure, fusion length welding is accurately, weld seam is relative to core pipe axial plane angle accurate positioning, compared with infinite place groove dividing plate, in the case of equivalent material, owing to flange slot treatment defines the length of welded seam, 100% meets design verification length requirement, controls welding wire consumption simultaneously, and welding wire use cost decreases, weld interval reduces, and entirety shortens weld interval.In conjunction with this 2 point, this structure has obvious advantage in terms of standardization and cost declining, also assures that position while welding endurance quality simultaneously.
Description
Technical field
This utility model belongs to a kind of automotive muffler partition plate, when dividing plate and core sealing of tube, limits fusion length.
Background technology
The waste gas discharged when the major function of gas extraction system is to be worked by electromotor and noise are by gas extraction system
The gases such as reaction, noise reduction process, H2O, the CO2 after being processed by tail pipe are discharged in air.Owing to electromotor is arranged
Going out gas temperature high, gas extraction system needs to be converted into harmful substance by chemical reaction the gases such as H2O, CO2, and will realize
Reducing the purpose of noise, therefore gas extraction system internal structure is complicated, to structure durability and meet discharge function and have harsh specification
Requirement.
Dividing plate and core sealing of tube are as one of main connected mode of gas extraction system internal structure, it is common that by dividing plate punching,
Flange, core pipe welds through circular hole with dividing plate at flange, owing to flange is circular, therefore is difficult to control to core pipe and turns over dividing plate
Weld length and weld seam relative level angle at limit, weld length can reduce again welding efficiency when ensureing.Especially manual welding
Time, it is difficult to ensure that welded seam extension consistency.
The control of fusion length directly affects whether acoustic filter allomeric function lost efficacy, whether cost control increases: weld seam is long
Degree deficiency, when dividing plate flange and core sealing of tube, endurance quality is poor, the most cracking then causes noise elimination function to lose efficacy；Fusion length
Long, welding wire consumes big, increases assembly weld interval, reduces production efficiency, then increases cost and quality guarantee detection difficulty.
Summary of the invention
This utility model provides a kind of silencer muffler partition plate that can limit fusion length, to solve to weld when core pipe welds with dividing plate
The seam unmanageable problem of length.
This utility model adopts the technical scheme that: include clapboard body, and at dividing plate circular cross-esction, outputing width is
The arc groove of 1mm, the arc length of this arc groove be with core sealing of tube at fusion length.
This utility model one embodiment is that clapboard body selects stainless steel material B436L, 441 or 409.
This utility model one embodiment is clapboard body thickness range 1-1.5mm.
The utility model has the advantages that novel structure, accurately, weld seam is relative to core pipe axial plane angle in fusion length welding
Accurate positioning, compared with infinite place groove dividing plate, in the case of equivalent material, owing to flange slot treatment defines welded seam
Length, 100% meets design verification length requirement, controls welding wire consumption simultaneously, and welding wire use cost decreases, weld interval
Reducing, entirety shortens weld interval.In conjunction with this 2 point, this structure has obvious advantage in terms of standardization and cost declining, with
Time also assures that position while welding endurance quality.

Detailed description of the invention
Including clapboard body 1, at dividing plate circular hole 102 flange, output the arc groove 101 that width is 1mm, this arc groove
Arc length is and the fusion length of core pipe 2 weld.
Clapboard body selects stainless steel material B436L, 441 or 409.
Clapboard body thickness range 1-1.5mm.
Operation principle, core pipe 2 inserts dividing plate circular hole 102, and core pipe 2 welds with clapboard body 1 at flange stopper slot 101,
The welding starting the arc, receipts acnode are the two ends original position of stopper slot, by flange stopper slot welding arc control fusion length.
