The automobile-used corrugated tube of this utility model is compared with the automobile-used oil return pipe of prior art, has an advantage in that, this utility model Simple in construction, does not use quality of rubber materials, and resistance to elevated temperatures is good, can be arranged in the place close to thermal source, reduces quality risk, Meanwhile, the song of corrugated regions is had mercy on characteristic, with the installation of personnel convenient to operate and in use can absorb and offset vibration Effect, effectively prevents the generation that stress is concentrated.
Accompanying drawing explanation
Fig. 1 is the structural representation of automobile-used corrugated tube embodiment one;
Fig. 2 is the structural representation of automobile-used corrugated tube embodiment two.
Detailed description of the invention
Below in conjunction with accompanying drawing, further illustrate specific embodiment of the utility model.
As it is shown in figure 1, the utility model discloses the embodiment of a kind of automobile-used corrugated tube.This corrugated tube be a kind of thin-walled not Rust corrugated steel pipe, this corrugated tube comprises: body 101, and is arranged on body 101 ripple needing bending or absorption to vibrate position Stricture of vagina structure 102.
Body 101 uses stainless steel material to make, and its two ends are provided with flange or joint, is connected by flange or joint mechanical Turbocharger or electromotor.
The external diametrical extent of body 101 is 12 millimeters to 16 millimeters.The wall thickness of body is 0.3 millimeter to 0.5 millimeter.
Further, corrugated tube wall thickness is an important geometric parameter, and (rigidity and work should for the key property of corrugated tube Power) depend on the physical dimension of corrugated tube, it is particularly depending on its wall thickness.The wall thickness of corrugated tube and internal diameter have certain ratio Relation, for the corrugated tube of inside diameter ranges 10 ~ 100mm, the ratio of wall thickness and internal diameter is 0.0006 ~ 0.05.If the thickest, it is soft Soft must be very poor;If the thinnest, its bearing capacity is restricted.Therefore, various corrugated tubes must be according to concrete use bar Part and performance requirement, according to the corresponding relation of internal diameter Yu wall thickness, select rational wall thickness.
If corrugated tube is a kind of high-pressure bellows, in order to reduce rigidity and the stress of corrugated tube, body 101 needs to be designed as Multiple structure, total wall thickness of the body 101 of this multiple structure and the ratio of internal diameter are less than or equal to 0.05.
Continuous print ripple struction 102 is formed by hydraulic pressure on body 101.
Wave mode refers to the corrugation pattern after axially cutting open and shape, and the bellows-shaped of corrugated tube affects corrugated tube Rigidity, displacement and bearing capacity.The shape of ripple struction 102 comprises: U-shaped, c-type, S type, V-type, or above-mentioned any bellows-shaped Combination.
The pitch of waves is corrugated tube and the important parameter of wave mode structure thereof, affects effective length and the performance of corrugated tube.This practicality In novel, the pitch of waves of ripple struction is directly proportional to body wall thickness, and the variation tendency of the pitch of waves is to increase with the increase of internal diameter.Ripple The pitch of waves of structure accounts for the percentage ratio of internal diameter of tube body and is inversely proportional to internal diameter of tube body, and the pitch of waves accounts for the percentage ratio of internal diameter then with the increase of internal diameter And reduce.
The corrugated tube thickness of convolution refers to the Breadth Maximum in outer corrugated portion axial face, and after the pitch of waves determines, the thickness of convolution is the most directly Affect the radius of corner of waveform angle, crest and trough.After the pitch of waves and the thickness of convolution determine, i.e. determine at waveform angle, crest and trough Figure angular radius.
The axial overall length of corrugated tube corrugated portion claims the effective length of corrugated tube, or claims the active length of corrugated tube.Ripple Stricture of vagina number and effective length are two parameters being closely related.In order to ensure to have when corrugated tube works reliable stability, this practicality The axial overall length of novel middle ripple struction and the ratio of outer tube diameter are less than or equal to 1.3.
If needing long effective length, can get up with two or more bellows-weldings, being connected into long ripple Stricture of vagina pipe, it would however also be possible to employ the corrugated tube of the method direct forming length such as single-bellow continuous.To the long ripple in addition to metal hose Pipe, in order to ensure its structural stability, it is necessary to interiorly or exteriorly arranges guide elements at corrugated tube.
As in figure 2 it is shown, be automobile-used corrugated tube embodiment two, in embodiment two, corrugated tube comprises rustless steel body 201, arranges Ripple struction 202 on body 201 equipment.
Further, body 201 is additionally provided with machine kinking structure 203.Body 201 after machine is curved is arranged on according to design requirement Engine end or turbocharger end, specifically to meet interface size and status requirement.
The curved technique referring to be carried out the bending of steel pipe by bending machine of machine.External diameter is D, and wall thickness is that the body 201 of t is by moment of face When the effect of M bends, outside tube wall tension stress effect, tube wall is thinning;Inner side tube wall tension stress effect, tube wall becomes Thick.And the shape of cross section is owing to being become approximate ellipsoidal by the effect of F1 and F2 with joint efforts from circle, when deflection is excessive, Outside tube wall can crack, and inner side tube wall there will be wrinkling.
The deformation extent of body 201, depend on relative bending radius R/D and the size of relative thickness t/D numerical value, R/D and T/D value is the least, represents that deformation extent is the biggest.For ensure corrugated tube forming quality, it is necessary to control deformation extent in tolerance band, The body 201 bending forming limit depends not only on mechanical property and the machine bending method of material, but also considers that the use of pipe fitting is wanted Ask.
The curved forming limit of body 201 machine should comprise following content: 1) if pipe fitting has the requirement of ovality, control Make its section and produce distortion;2) if pipe fitting has the requirement of strength bearing interior pressure, the forming limit of its wall thickness reduction is controlled; 3) in stretcher strain district, outside, maximum elongation strain produces rupture less than material plasticity permissible value;4) inboard compression deformation In district, unstability will not be exceeded and wrinkling by the thin-wall construction part of circumferential compressive force effect.
Although content of the present utility model has been made to be discussed in detail by above preferred embodiment, but it should be appreciated that The description stated is not considered as restriction of the present utility model.After those skilled in the art have read foregoing, for Multiple amendment of the present utility model and replacement all will be apparent from.Therefore, protection domain of the present utility model should be by appended Claim limit.
