Abstract
A branch-type encapsulated joint for the connection of main and branch hoses. It is characterized in that: the encapsulated joint comprises of main encapsulated pipe [7], branch encapsulated pipe [5] and the internal extruding ring [8] which is set at the joining place in between the main encapsulated pipe and branch encapsulated pipe set on the internal wall surface of the encapsulated joint. This sort of joint can be applied to prevent the stress concentration at the joint place between the main pipe and branch pipe, thus greatly improve the pulse pressure resisting performance of the encapsulated pipe.
Description
Technical field
The utility model relates to a kind of rubber product, specifically, relates to the jointing that a kind of rubber hose is used.
Background technique
Being widely used in each department of national economy based on the rubber hose of conveying material, particularly, is the automobile sebific duct of representative with the car, and in recent years along with developing of automobile industry, its looks have had very big change.For small-sized, compactness and the high-power that realizes car, the sebific duct that is used to transmit oil, vapour, cooling liquid etc. has many requirements to make multichannel ramiform structure, so that can be contained in the less space, playing originally need be than the function on the multitube road of large space.Because this class sebific duct need bear certain pressure mostly, so must adopt enhancement layer
The multi-layer structure of (fabric or wire) is because its complex forming technology can not be made multichannel ramiform sebific duct with the mould pressing process of general gum goods.Usually need make basic straight type or curved sebific duct earlier,, peg graft, wrap one deck glue at main sebific duct and the seam crossing that props up sebific duct and strengthen method such as seam and make then by perforate.The ramiform sebific duct of so making occurs stress the person in charge easily with the arm splicing position and concentrates, and becomes to cause the early stage weak link of damaging of sebific duct.For example, a kind of car vent systems ramiform sebific duct is arranged, its performance assessment criteria of dispatching from the factory is: every 2s pulsatile once in 150 ℃ of hot airs, pressure 2bar, do not leak for 100,000 times, in fact, with the ramiform sebific duct of above-mentioned conventional method manufacturing after having born 1000 subpulse pressure, cracking or leakage will take place in the encapsulate joint, do not satisfy car design office requirement.
Summary of the invention
The utility model is intended to overcome the shortcoming of the existing ramiform sebific duct person in charge and arm seam joints, provides a kind of concentrated hidden danger that can eliminate stress, the novel structure encapsulate joint that joint strength is enhanced.
The utility model is to realize like this, it provides a kind of ramiform sebific duct person in charge to be connected with arm and uses the encapsulate joint, it is characterized in that the formation of described encapsulate joint comprises: main encapsulated pipe, branch encapsulated pipe and be arranged on the internal projecting ring of main encapsulated pipe and branch encapsulated pipe joint on the encapsulate inner nosepiece wall face.And each component part of described encapsulate joint comprises that main encapsulated pipe, branch encapsulated pipe and internal projecting ring constitute by the injection moulding pressure injection is whole.Like this, whole joint does not have seam and so on vulnerable area, and the High Temperature High Pressure that forms when adding injection moulding can guarantee the person in charge of formed encapsulate joint and ramiform sebific duct and the outer wall strong bond of arm, guarantees essential joint strength and durability.
For fear of forming stress concentration point the person in charge of ramiform sebific duct and the seam crossing of arm, the utility model specially on encapsulate inner nosepiece wall face main encapsulated pipe and branch encapsulated pipe joint be provided with the internal projecting ring that is embedded in this seam, make sebific duct do the time spent bearing pulsating pressure, internal projecting ring can produce the effect of buffering and stress dispersion, for reaching this purpose, according to the basic design principles of rubber product, this internal projecting ring has fan-shaped section, more helps stress and disperses.
In order to make the encapsulate joint not only have enough intensity but also to be unlikely to too to increase the volume of ramiform sebific duct, influence the assembly space of whole mechanical device, the size of described encapsulate joint is preferably:
The wall thickness of main encapsulated pipe and branch encapsulated pipe is respectively the ramiform sebific duct person in charge and a thickness of pipe wall 0.5～2 times;
The length of main encapsulated pipe is 1.5～2.5 times of external diameter of ramiform sebific duct arm, 2～5 times of the wall thickness that the length of branch encapsulated pipe is responsible for for the ramiform sebific duct.
By above-mentioned visible effect of the present utility model is conspicuous, structure at first of the present utility model has comprised main encapsulated pipe and branch encapsulated pipe, and it is again to constitute by injection moulding is whole, thereby at seam crossing humidification is arranged all for the person in charge and the arm of ramiform sebific duct, particularly be responsible for glue-line section configuration with the seam crossing encapsulate joint of arm just as the flange-like flange, thickness obviously increases, and can guarantee enough strength and stiffness, thereby can effectively prevent the fatigue damage of rubber.Secondly, internal projecting ring the problem of stress concentration that has solved seam crossing is set, further improved the ramiform sebific duct and be responsible for durability with the arm joint.
Description of drawings
Fig. 1 is the schematic representation that the ramiform sebific duct uses the conventional bag cemented joint; Fig. 2 is the schematic representation that the ramiform sebific duct uses the utility model encapsulate joint.
Label among the figure is: 1,4---the arm of ramiform sebific duct; 2---traditional encapsulate joint; 3,6---the person in charge of ramiform sebific duct; 5---branch encapsulated pipe; 7---main encapsulated pipe; 8---fan-shaped section internal projecting ring.
Embodiment
Below in conjunction with accompanying drawing, by embodiment the utility model is further described in detail, but the utility model is in no way limited to this embodiment.
Embodiment
Referring to accompanying drawing 1, the drawing schematic representation that this former foreign side of a kind of ramiform sebific duct that is Passat B7 type motorcar engine vent systems is used provides.The person in charge's of ramiform sebific duct [3] wall thickness is 5mm, internal diameter 51.5mm, and the wall thickness 3.5mm of arm [1], internal diameter 24mm is with the internal diameter 18.5mm that is responsible for the joint.The wall thickness 5.5mm of encapsulate joint [2].Requirement can be born every 2s once in 150 ℃ of hot airs, the pulsating pressure of pressure 2bar is tested 100,000 times, do not take place to leak and damaged, but the sebific duct of making by this encapsulate joint is in the pulsating pressure test of regulation, joint area often promptly leaks less than 1000 subpulses.Afterwards, use the utility model encapsulate joint as shown in Figure 2 instead, the size constancy of the person in charge of ramiform sebific duct [6] and arm [4] wherein, the encapsulate joint is made of branch encapsulated pipe [5], main encapsulated pipe [7] and the internal projecting ring [8] that is arranged on main encapsulated pipe and branch encapsulated pipe joint on the encapsulate inner nosepiece wall face, this internal projecting ring gos deep into the ramiform sebific duct to be responsible in the seam of [6] and arm [4], and having fan-shaped section, whole encapsulate joint forms by injection moulding Integratively pressure injection.Wherein, the length 48mm of main encapsulated pipe, wall thickness 5.5mm, the length 6mm of branch encapsulated pipe, wall thickness 5.5mm.
Joint leakage or damaged through 100,000 subpulse pressure effects, does not take place in the ramiform sebific duct that adopts this encapsulate joint more than 98% in the pulsating pressure test of afore mentioned rules.
