Description
Technical field
It the utility model is related to forming high pressure in pipe field, more particularly to a kind of sawtooth pattern for sealing pipeline port
Cut somebody's hair structure.
Background technology
Axial direction plus side thrust carries out feed supplement while forming high pressure in pipe is by being pressurizeed to tubing internal filled liquid, forces
Tube billet fits to mold cavity under the pressure effect of pressure medium, realizes a kind of technique of pipe shaping.In its tubing
The pressure of portion's topping up pressurization is generally up to 100MPa-400MPa, and most formation of parts need to also keep one under its high pressure conditions
The packing state of section time can be only achieved preferable forming effect, therefore the quality of its end sealing structure, directly influence superelevation
Can pressure condition be realized, be got a desired effect so as to have influence on tubing part forming, so end sealing structure is fine or not
It is most important for internal high pressure forming technique.
Traditional end sealing is processed into cone using both ends of the surface are cut somebody's hair, and the conical surface is pushed down into end surfaces reality in responsive to axial force
Now seal.Using such a sealing structure, often during press-in of cutting somebody's hair, pipe feeding resistance is caused to increase or be stuck in mould
In die cavity, make mould or cut somebody's hair abrasion, deformed damaged, the service life and the reliability of work for have a strong impact on mould, cutting somebody's hair.Separately
Outside, the radial dilatation of the mouth of pipe is easily caused using such a end sealing, the difficulty of pipe feed supplement can be increased, causes tube wall during shaping to become
Thin or rupture, situation severe patient will cause to cut somebody's hair directly stuck in mold cavity with pipe fitting.
Sealing structure disclosed in Chinese invention patent CN101011715, it is not only complicated, and easily cause a both ends left side
Bulging at right pilot hole.Adopting the structure, cut somebody's hair complicated, anufacturability is poor, and manufacturing cost is high, and rubber is softer,
Because internal pressure is big, abrasion is very easy to, it is often necessary to change, not only increase cost, and lose time.
Sealing structure disclosed in Chinese utility model patent CN202097262U, is adopted the structure, and is cut somebody's hair in big axle
To under thrust, the pipe material that pipe end contacts with thrust platform of cutting somebody's hair easily collapses, at this moment due to conical surface seal face
In the presence of, cut somebody's hair continue feeding during can equally easily cause the radial dilatation of the mouth of pipe, increase the difficulty of pipe feed supplement, hold
Tube wall is thinning when easily causing shaping or ruptures；And when the heavy platform processing of the pipe end conical surface has mismachining tolerance, the heavy platform of the pipe end conical surface is deep
Spend deeply and mouth of pipe radial dilatation easily occur and the heavy platform depth of pipe end is dived and the bad situation of conical surface seal face sealing easily occurs excessively.
Utility model content
The utility model is solves existing technological deficiency, there is provided a kind of sawtooth pattern for sealing pipeline port is cut somebody's hair knot

The utility model is further elaborated below in conjunction with the accompanying drawings.Fig. 1 is referred to Fig. 4.
The utility model discloses a kind of sawtooth pattern for sealing pipeline port and cut somebody's hair structure.Structure of cutting somebody's hair 10 is in cone
Type, it includes correcting section 102, toothed segment 103, thrust platform 104.Toothed segment 103, thrust platform are sequentially provided with after correcting section 102
104.Correcting section 102, toothed segment 103, the cross sectional shape of thrust platform 104 are identical, and its shape is according to the pipe end degree of lip-rounding that need to be processed
It is identical with the shape of pipe end depending on shape.Because pipeline is generally circular in cross section, correcting section 102, toothed segment 103, thrust platform 104
Section it is preferably circular, correcting section 102, form the boss of toothed segment 103, thrust platform 104 is preferably cylindrical type.Correcting section
102nd, toothed segment 103, thrust platform 104 press cone-shaped arrangement, and the section of the minimum boss of toothed segment 103 is bigger than correcting section face, only
It is bigger than the section of the maximum boss of toothed segment 103 to push away platform 104.During work, pipeline 20 to be processed is first put into the inside of mould 30, so
The both ends of 10 sealing pipeline of pusher header structure 20, by then toward water filling in pipeline 20, being molded pipeline 20.Below, respectively to leading
Positive section 102, toothed segment 103, the operation principle of thrust platform 104 are described further.
Correcting section 102：It is provided with chamfering 101, and main function is that guiding is cut somebody's hair into pipeline 20.In order to prevent conventional junction
There is the stuck phenomenon of correcting section because manufacture perpendicularity of cutting somebody's hair is bad in structure.Correcting section 102 is also slightly smaller than pipeline inner port, in order to
Fully ensure that pipeline 20 and the axiality of structure 10 of cutting somebody's hair, it is ensured that axial side-thrust stepless action is in 20 liang of pipe ends of pipeline, simultaneously
The sealing air-tightness of enhancing pipeline 20 ensures that internal high pressure can be established normally.Originally the correcting section 102 of structure of cutting somebody's hair 10 is than general knot
Structure it is short.
Toothed segment 103：For stretching into sealing pipeline 20 in pipeline 20 and providing axial thrust to pipeline 20, it is located at and led
The side of positive section, including multistage sectional area is by small boss, the joint face of boss described in multistage and the center of the structure of cutting somebody's hair
Line is vertical, and the less boss of sectional area is more than the sectional area of correcting section 102 close to the sectional area of correcting section 102 and the boss, convex
For platform to be cylindric, toothed segment 103 sets three to five sections of boss to extrude to form three to five and enclose rigidity with pipe end inwall and contact sealing
Circle, preferably five sections.The straight line and the angle of the center line for structure 10 of cutting somebody's hair that the convex edge of table of multistage is linked to be are 15 °~20 °,
In the angular range, the sealing ring that boss forms pipe end is more rigid, further, it is preferable to be 18 °.When structure 10 of cutting somebody's hair
When compressing axially pipe end, the multistage boss in toothed segment 103 produces axial compression with pipe end inwall, and the scene-affinity of multistage boss is in
The tight inwall of pipeline 20 is tightly stung in the presence of thrust, the inwall of pipeline 20 is plastically deformed multi-turn rigidity Contact Seal ring；
Due to the knot of small thrust platform that multi-turn is formd in plastic deformation caused by the inwall part of pipeline 20 extruded with toothed segment 103
Structure, the boss of toothed segment 103 are evenly steady to axial force caused by the inwall of pipeline 20 so that axial supplement is more equal
It is even；The small thrust platform structure formed, which will not also produce radial load under the continuous effect of thrust avoiding problems the conventional belt conical surface, to be pushed away
The drawbacks of pipe end radial dilatation caused by the lower pipe end of head effect is acted on by component is brought, can effectively eliminate pipe port expansion and
It is stuck in mold cavity phenomenon so that charging feed supplement it is more smooth, beneficial to the shaping of pipeline.
Thrust platform 104：For the side wall to conjunction pipeline 20 port with when the toothed segment 103 provides axial thrust deficiency
Make up axial thrust and the further port of sealing pipeline 20.Its structure is one against toothed segment 103 and is more than toothed segment 103
Cylinder, when toothed segment 103 produce axial thrust deficiency when, at this moment thrust platform 104 can farthest press pipeline 20 and manage
End, making up axial supplement thrust ensures the smooth progress of feed supplement energy, at the same time forms thrust sealing ring enhancing sealing.
