The automobile exhaust decorative tail tube has the advantages of convenient use, easy processing, corrosion resistance, and capacity of smoothing the automobile exhaust relative to the flanged decorative tail tube.
Description
Technical field
The present invention relates to a kind of automobile exhaust decorative tail tube, be specifically related to a kind of automobile exhaust decorative tail tube.The invention still further relates to the processing method of automobile exhaust decorative tail tube.
Background technique
At present, the outlet end of the automobile exhaust decorative tail tube that people adopt is adding man-hour, generally all is provided with the crimping mouth.When packing, transportation, use, can avoid other objects are scratched or scratch.But also exist not enough: first processing is inconvenient, cost is high; It two is the exhausts that influence automobile, and is when promptly the automobile gas of discharging is through the tail pipe end, smooth and easy inadequately; It three is decorative tail tube ends of automobile exhaust pipe owing to be provided with wiredrawn edge, and the sediments that long-pending easily automobile is discharged finally causes automobile exhaust pipe to rot, lost efficacy.
Summary of the invention
The technical problem that (one) will solve
The purpose of this invention is to provide a kind of easy to usely, easy processing can guarantee automobile exhaust automobile exhaust decorative tail tube smoothly.The object of the invention also provides a kind of processing method of automobile exhaust decorative tail tube.
(2) technological scheme
In order to achieve the above object, the present invention takes following scheme:
Automobile exhaust decorative tail tube of the present invention, the end of this tail pipe is the curved surface shape, and edge is provided with the metal coat body in the curved surface end.
Wherein, the end curved surface shape of said tail pipe is formed a kind of decorative pattern shape at least.
Wherein, said metal coat body is convex shape along the longitudinal cross-section of tail pipe discharge directions.
Wherein, the end of said tail pipe comprises straight mouthful and angle.
The processing method of automobile exhaust pipe of the present invention has following steps:
1) end face that utilizes laser will make the tubing of automobile exhaust decorative tail tube cuts into the edge with certain curved surface;
2) metal powder material is rendered to the end of above-mentioned curved surface;
3) utilize laser that metal powder material is molten to above-mentioned cutting curved surface end;
4) with the energy of laser with the metal powder material fusion on the above-mentioned curved surface, at place, curved surface end, form smooth metal coat body.
Wherein, said step 2) also be included in the curved surface place powder is thrown in slightly protruding step.
(3) beneficial effect
(1) the present invention has changed the original inwardly structure of crimping owing to be provided with the metal coat body that is dimpling shape in the tail pipe end of automobile exhaust pipe, and waste gas can pass through tail pipe swimmingly during automobile exhaust; (2) the decorative tail tube end of automobile exhaust pipe does not have the crimping mouth, and partial impurities, sump oil and the dust etc. in the waste gas that automobile is discharged can not deposit in the tail pipe end of automobile exhaust pipe; (3) owing to be provided with the metal coat body in the tail pipe end of automobile exhaust pipe, this metal coat body is compared with automobile exhaust tail pipe steel has better corrosion resistance; (4) the decorative tail tube end of automobile exhaust pipe is processed to curve form, promptly forms decorative pattern in the tail pipe end of automobile exhaust pipe, has both increased effect attractive in appearance to automobile exhaust pipe, further makes automobile exhaust more smooth and easy again; (5) owing to adopted laser beam machining, the processing of automobile exhaust pipe is more convenient, and efficient is higher.

Among the figure: 1, automobile exhaust pipe tail pipe; 2, curved surface; 3, metal coat body.
Embodiment
Following examples are used to explain the present invention, but are not used for limiting scope of the present invention.
Referring to Fig. 1, Fig. 2:
1. a kind of automobile exhaust decorative tail tube of the present invention is provided with several curved surfaces 2 in the end of tail pipe 1; 2., be provided with metal coat body 3 at the place, end of this curved surface 2; 3., said curved surface 2 is processed circular arc, also can process the rectangle of rounding off, and from appearance, decorative tail tube 1 shape of automobile exhaust pipe just can form various decorative patterns, and is very attractive in appearance, helps automobile simultaneously and discharges tail gas more swimmingly.
Referring to Fig. 3: said metal coat body 3 is convex shape along the longitudinal cross-section of the discharge directions of automobile exhaust decorative tail tube.Just because of such convex shape structure is arranged, the tail pipe 2 of automobile exhaust pipe is smooth to the touch, neither can in packing, transportation, using process, hurt human body or scratch object, help automobile again and discharge tail gas swimmingly.
Referring to Fig. 1, Fig. 4, Fig. 5, Fig. 6, decorative pattern that tail pipe top-surface camber according to the invention is formed and the metal coat body on the tail pipe both can be located at the end of automobile exhaust pipe tail pipe for straight mouth, also can be located at the end that the automobile exhaust pipe tail pipe is an angle.
The processing method implementation step that the present invention is used for above-mentioned automobile exhaust pipe is following:
1) exhaust one end-grain cutting that utilizes laser will make the tubing of automobile exhaust decorative tail tube is slit into the edge with several curved surfaces 2.Laser beam is focused into very little luminous point, makes along reach very high specific power.The heat of light beam input at this moment (by transform light energy) is considerably beyond by material reflection, conduction or diffusion section, and material is heated to vapourizing temperature very soon, and evaporation forms hole.Along with light beam and material move relative to linear, make hole form the joint-cutting of narrower in width continuously.The side cut heat affecting is very little, does not have workpiece deformation basically.And laser beam cutting do not have burr, and fold, precision are high, are superior to the plasma cutting.Because laser cutting system can conveniently cut the workpiece of difformity and size, it often than die-cut, mould pressing process is more convenient; Although its processing speed is slower than stamping, it does not have mould consumption, need not to repair mould, also practices thrift the more mold exchange time, thereby saves processing charges, reduces product cost, so more worthwhile economically on the whole.
2) metal powder material is coated to the end of above-mentioned curved surface 2; At this place metal powder material is applied as slightly convex shape.
3) utilize laser that metal powder material is molten to above-mentioned end; This laser cladding is a kind of special metal surface enhanced technology, and it is the controlled heat that is derived from laser through utilization, metal powder material is melted be applied on the plate surface to reach the surface peening effect.This laser cladding can provide stronger metallographic bonding at metal powder material and these two kinds of intermetallics of sheet material, accompanies by the sheet material dilution of minimum degree simultaneously.The required heat of laser cladding is imported very little, thereby the heat-affected zone that is caused is also very little, and sheet material has only very little zone and metal powder material together to melt to produce the metallographic bond effect in the laser cladding process.And the heat energy input of this laser cladding can accurately be controlled, and the thermal distortion that is therefore produced is minimum, and the heat energy input of this very small amount can prevent that product from deforming, and is also minimum to the sheet material The properties simultaneously.
4) laser is molten to place, curved surface 2 ends with the metal coat material and forms smooth metal coat body 3.
The XY type multifunction laser processing machine system of Wuhan sky above Hubei and Hunan industrial lasers equipment Co., Ltd public offering is adopted in processing such as laser beam cutting of the present invention, laser cladding, laser bonding.
