Abstract
The tube body is a three-layer structure, the inner and middle layers are two superimposed stainless steel bellows with 9-19 of wave number, the misplacement of the weld seams of the two layers is about 180 deg, the outer layer is a screen casing weaved with stainless steel wire, which is closely nestling to the bellows and fixed on two ends of the bellows with weld hoops. The productive process consists of plate cutting, tubing, shunk-on, weaving, fixing with weld hoop etc.. The present invention will produce vortex while exhausting to avoid the direct-flow exhausting and features anti-fatigue, anti-vibration and reducing noise, and improves significiently the operational property of the automobile and prolongs the servic life of the automobile's engine and exhaust pipe.
Description
The present invention relates to the layout that a kind of vehicular propulsion combines with exhaust, relate in particular to a kind of metallic bellows hose specially used for automobile exhaust and production technology thereof.
Automobile engine exhaust pipe in use expands with heat and contract with cold and can cause axial displacement, advances at road and easily causes the damage of outlet pipe fracture or other link when jolting, and need set up the antivibration elastic compensating device by the exhaust pipeline section before silencing apparatus.
The objective of the invention is to remedy the deficiencies in the prior art and propose a kind of metallic bellows hose specially used for automobile exhaust and production technology thereof with good antivibration elastic compensating function.
Purpose of the present invention is achieved by the following technical programs.
This metallic bellows hose specially used for automobile exhaust, body is a corrugated, the two ends caliber equates with the outlet pipe caliber of adapted, and respectively with outlet pipe before, the stage casing is weldingly connected, it is characterized in that body is three stratiform structures, in, the middle level is that the wave number made from Stainless Sheet Steel of two superimposed is 9-19 bellows body, 180 ° ± 20 ° of two-layer weld seam dislocation, skin is to be close to bellows body and with the fixing stainless steel braiding silk screen outer cover in weldering hoop and body two ends.
The production technology of above-mentioned metallic bellows hose specially used for automobile exhaust is:
A, inner and outer pipes shear (corrosion resistant plate), reel, weld seam, inner and outer pipes suit (180 ± 20 ° of weld seam dislocation), shaped by fluid pressure, cleaning are deoiled;
B, stainless steel steel wire plying, braiding stainless (steel) wire outer cover;
C, stainless (steel) wire outer cover two ends are fixed on the inner and outer pipes that cover installs with weldering hoop.
The present invention is novel, easy for installation, do not change the automobile original structure, owing to be provided with ripple struction, in exhaust process, can produce eddy current, avoiding the direct current exhaust, and bullet stretchability, compressibility and the sheathed of its antifatigue, softness is freely in running can to make vent systems, durable in use, resist tired anti-vibration reducing noise sound, improve the usability of automobile significantly, prolong the working life of motor car engine and outlet pipe.Its production technology is practical, easy row.
Accompanying drawing is a structural representation of the present invention.
Below in conjunction with embodiment and contrast accompanying drawing the present invention is made an explanation.
Metal bellow with Jiangxi Isuzu Motors light truck outlet pipe adapted, 164.4 millimeters of pipe ranges, 57.5 millimeters of weldering hoop (1) external diameters, internal layer (2), middle level (3) are that the wave number of the two superimposed made with the OCr19Ni19 Stainless Sheet Steel of 0.4 millimeters thick is 9 bellows body, 180 ° ± 20 ° of two-layer weld seam dislocation, outer (4) are to be close to stainless steel mesh grid outer cover bellows body, that also fix with weldering hoop 1 and body two ends, weave by 115 ° of braid angles by 48 braids in this outer cover, and every braid is made up of 12 steel wires.Its production technology is as follows:
A, inner and outer pipes shear (corrosion resistant plate), reel, weld seam, inner and outer pipes suit (180 ± 20 ° of weld seam dislocation), shaped by fluid pressure, cleaning are deoiled;
B, stainless steel steel wire plying, braiding stainless (steel) wire outer cover;
C, stainless (steel) wire outer cover two ends are fixed on the inner and outer pipes that cover installs with weldering hoop.
Claims (2)
