Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of automobile engine intake tube and integration system fabrication technique thereof, its structure is simple, reasonable in design, and production technology is simple, reduces production cost.
Technical scheme of the present invention is achieved in that a kind of automobile engine intake tube comprises bend pipe and gradual change pipeline section, it is characterized in that, described bend pipe and gradual change pipeline section are integrated, and described bend pipe front end is provided with front annular projection, and the rear end of gradual change pipeline section is provided with rear annular projection; Described automobile engine intake tube entirety adopts melting aludip material to make.
Present invention also offers a kind of integration system fabrication technique of automobile engine intake tube, comprise the following steps:
A) cut, according to length of run size, automatic gas cutting machine cuts open circles materials in the tube;
Chamfering, on beveler, is carried out in the material two ends cut by b) chamfering;
C) expander, installs machine for shrinking mold, is transferred to maximum by draw stroke, and examination is expanded.Control length by adjustment stroke, carry out expander, the shape of processing gradual change pipeline section;
D) bend pipe, bending machine installs mould by frock number and harmonizes, and it is curved that starting device mixes up angle examination, qualified rear beginning bend pipe work, the bending angle of processing bend pipe;
E) revolve bag, rotary packing machine finds mould accurately by frock number, install and harmonize, screw out described front annular projection and the ring-type bulge of rear annular projection two place respectively.
Preferably, the thickness of described step open circles materials in the tube a) is 1.5mm.
The invention solves the defect existed in background technology, there is following beneficial effect:
Automobile engine intake tube provided by the invention adopts melting aludip material to make, its compact conformation, reasonable in design, the automobile engine intake tube produced, its bend pipe and gradual change pipeline section are integrated, smooth surface is smooth, camber line is smooth, air inlet pipe can be made when being connected with flexible pipe by the forward and backward annular projection arranged at bend pipe and gradual change pipeline section two ends, fixation.The integration system fabrication technique that this invention provides, eliminate the pressure check operation after traditional welding, polishing, welding, surperficial antirust treatment and the multiple working procedure such as zinc-plated, make production technology simple, reduce labour intensity and the production cost of workman, improve production efficiency and add economic benefit.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
A kind of automobile engine intake tube as depicted in figs. 1 and 2, comprises bend pipe 1 and gradual change pipeline section 3, and bend pipe 1 and gradual change pipeline section 3 are integrated, and bend pipe 1 front end is provided with front annular projection 2, and the rear end of gradual change pipeline section 3 is provided with rear annular projection 4; Automobile engine intake tube entirety adopts melting aludip material to make.Melting aludip is the aludip of cold-rolled steel sheet through aluminizing, the engineering properties therefore with cold-rolled steel sheet also has the characteristic such as heat resistance, corrosion resistance, heat reflectivity of aluminium outward, this melting aludip is called AL-COT, and full name is Hot Dip Aluminium Coated Steel.The main component of the overlay coating of this melting aludip is Al-Si (8 ~ 10%), has good heat resistance.In addition this aludip good processability, its extension property and the rate of curving functional, bending machine can not leave fold and bending trace after bending, can ensure that finished surface is smooth.Front annular projection 2 in air inlet pipe and the outside dimension of rear annular projection 4 2mm ~ 3mm larger than the outside dimension of corresponding bend pipe 1 and gradual change pipeline section 3, when air inlet pipe can be made like this to be connected with flexible pipe, make Hose Jacket on front annular projection 2 and rear annular projection 4, difficult drop-off, makes flexible pipe fixing reliable.
