Sample can be as the tube-like piece for appropriate purpose, and technical solution provided by the present invention reaches corresponding purpose.Also, to the greatest extent
Pipe will be illustrated mainly in subsequent explanation by taking delivery pipe as an example, but manufacturing method provided by the invention can be used for as
The manufacture of other tube-like pieces such as cylinder, oil cylinder.
For ease of understanding, it in subsequent explanation, describes to utilize manufacturer provided by the invention first by taking delivery pipe as an example
Then the preferred structure of delivery pipe made from method is described in detail the committed step of manufacturing method provided by the invention, this
Field those of ordinary skill from comprehension in the explanation of the preferred structure and committed step and can implement the right that is appended of the present invention
Every technical solution that claim is limited.
With reference first to shown in Fig. 1, using delivery pipe a kind of made from the manufacturing method of the present invention, which includes supervisor
1st, the fiber for being respectively arranged at the pipe connections 2 (such as flange) at the both ends of the supervisor 1 and being coated on the peripheral surface of supervisor 1 is answered
Condensation material layer 3.With traditional technology similarly, the delivery pipe of this structure can easily utilize supervisor by appropriate setting
1 wear-resisting property and the high characteristic of the specific strength of fiber composite layer 3, with ensure delivery pipe is wear-resisting, before explosion-proof performance
The purpose of putting, realizing lightweight.
Importantly, with reference to shown in Fig. 2 and Fig. 3 b, in delivery pipe provided by the invention, it is set to the pipe of the end of supervisor 1
Fluted 21 are formed on the peripheral surface of connector 2.Fiber composite layer 3 includes the axially extending axial direction fibre along supervisor 1
31 and along the circumferentially wound in the first circumferential fibers 32 on the axial direction fibre 31 of the supervisor 1, which is located at
Axial direction fibre 31 is locked to pipe connections 2 in the groove 21.It should be noted that of the present invention be formed in Guan Lian
Groove 21 on fitting 2 can be formed as various appropriate structures, as long as it can be convenient for making the first circumferential fibers 32 in axial direction
Axial direction fibre 31 is securely locked, avoids first circumferential fibers 32 in axial float, belongs to the conception range of the present invention.It should
The preferred structure of groove 21 will be described in detail in subsequent preferred embodiment.In addition, herein and undulation degree as described below
The extending direction of material, it can be understood as form the extending direction of the fiber yarn 4 of the fibrous material.For example, 31 edge of axial direction fibre
It is axially extending, that is, refer to the first then described fiber yarn 41 and axially extend.
By above-mentioned setting, during delivery pipe is manufactured, can (for example, twining silk head using multiple) simultaneously in an axial direction
Fiber yarn 4 (being specially the first fiber yarn 41) is laid with, to be rapidly formed axial direction fibre 31, convenient for effectively improving fiber lay down
If the manufacture efficiency of efficiency and delivery pipe.Also, it since the axial direction fibre 31 axially extends, can more uniformly be laid with
On supervisor 1, and can its tensile resistance be greatly axially being played, improve the axial strength of delivery pipe and be responsible for 1 and pipe
Bonding strength between connector 2.In addition, axial direction fibre 31 is locked in the groove 21 of pipe connections 2 by the first circumferential fibers 32
It is interior, for being firmly attached the pipe connections 2, avoid coming off under the effects that material impact.Since pipe connections 2 mainly use
This mode is connected on supervisor 1 and (can not depend on the modes such as welding and ensure bonding strength), therefore will not quenching to supervisor 1
Hardness, which can generate, to be significantly affected, and ensure that the wearability of delivery pipe.
If it can thus be seen that merely for improve manufacture efficiency and improve pipe connections 2 axial bonding strength purpose,
Axial direction fibre 31 may not necessarily axially extend, but with appropriate helical angle (0 °~90 °), it can equally utilize first week
Improve axial bonding strength to the locking effect of fiber 32, so as to need not excessively pay close attention to itself and master when being laid with axial direction fibre 31
The degree of engagement of pipe 1, so as to improve manufacture efficiency.Similarly, the first circumferential fibers 32 also need not be as shown along perpendicular to master
The direction extension of the center line of pipe 1, but can tilt and prolong along the track of the groove 21 for example when groove 21 is inclined to set
It stretches, as long as axial direction fibre 31 can be locked in groove 21 by it.
It should be understood that the present invention is not precluded and pipe connections 2 is fixed to master in advance for example by way of spot welding
The end of pipe 1, the step of in order to implement covered fiber composite layer 3.I.e. delivery pipe of the invention can be laid with
Remain to keep the connection of supervisor 1 and pipe connections 2 when stating axial direction fibre 31, but this connection is not intended as both offers connection by force
The main source of degree, but as a kind of pretreatment mode for facilitating the processing step for implementing covered fiber composite layer 3.
Under this situation, pipe connections 2 can also be pre-attached to the end of supervisor 1 by other means, for example, can be by 1 inserting of supervisor
Into pipe connections 2.However, this mode unnecessarily makes the modified internal diameter in the inner cavity of delivery pipe, it is not only possible to hinder
Flowing of the material in the inner cavity, and increase material and convey the active force of pipe fitting, larger axial force is easily generated, into
And lead to increased wear, Joint failure.For this purpose, in a kind of preferred embodiment of the present invention, pipe connections 2 are coaxially
(such as passing through welding) is docked to the end for being responsible for 1, and the pipe connections 2 have identical internal diameter with supervisor 1.So as to conveying
Pipe has the substantially invariable inner cavity of internal diameter, effectively reduces interaction in the axial direction between material and delivery pipe.
As shown, the peripheral dimension of the main part of pipe connections 2 is typically larger than the peripheral dimension of supervisor 1, and first
Circumferential fibers 32 make the locking of axial direction fibre 31 axial direction fibre 31 to generate prestressing force in itself, are easy to cause fiber yarn
It is difficult to be bonded the surface of supervisor 1 or pipe connections 2 well, makes between fiber composite layer 3 and supervisor 1 or pipe connections 2
Gap is generated, which will cause fiber composite layer 3 that can not play its effect well.In addition, being laid with axial direction fibre
When 31, it may cause fiber yarn that cannot strictly axially extend due to the problems such as precision so that axial bonding strength is not
It can achieve the effect that anticipation.For this purpose, with reference to shown in Fig. 3 g, in a kind of delivery pipe of preferred embodiment, fibrous composite
Layer 3 further includes the second circumferential fibers 33, which is responsible for 1 port around the direction of the pipe connections 2, and
It is circumferentially wound on axial direction fibre 31, so as to which axial direction fibre 31 be made to be fitted in well on 1 peripheral surface of supervisor and answered with pre-
Power.Since axial direction fibre 31 can be not only tightly engaged on supervisor 1, but also in tight state, therefore can effectively play
Its due effect is obviously improved the overall performance (particularly axially intensity) of delivery pipe.From the foregoing it can be seen that
During manufacturing delivery pipe, the winding of the second circumferential fibers 33 should be wound in the first circumferential fibers 32 to be completed to carry out later, this will
It is described in detail in the manufacturing method of subsequent delivery pipe.
Above-mentioned axial direction fibre 31 is mainly used for improving the axial strength of delivery pipe, can not improve explosion-proof performance, and if should
Axis fiber 31 is exposed to outside, since it is circumferential evenly distributed, it is easy to be come off in outer masterpiece under (as collided).Cause
This, in further preferred embodiment of the present invention, fiber composite layer 3 further includes the spiral shell being wound on axial direction fibre 31
Fiber (not shown) is revolved, optionally, which can also wind above-mentioned first circumferential fibers, 32 and second circumferential fibers 33.
So as to which fiber composite layer 3 has the outer layer that the internal layer of the composition of axial direction fibre 31 and spiral fiber are formed on the whole so that
Delivery pipe both has larger axial strength, it may have good explosion-proof performance.
Preferably, the helical angle of the spiral fiber is 70 °~90 °.31 energy of axis fiber just as described above, of the invention
It is enough axially to give full play to its tensile resistance, therefore ensure that the axial strength of delivery pipe.In this case, spiral fiber twines
Around to have larger helical angle, so as to mainly play a role in the circumferential, for preventing supervisor 1 excessively swollen radially
It is swollen and make delivery pipe have good explosion-proof performance.
It is understood that axial direction fibre 31 of the present invention, the first circumferential fibers 32, the second circumferential fibers 33 and spiral shell
Rotation fiber is only used for distinguishing the difference of set-up mode and the form being arranged on after being responsible on 1 when it is laid with or winds, not by it
Substantially different fibrous composites is defined to, for example, these fibers can be formed by same group of fiber yarn 4.This is especially
Suitable for the situation that axial direction fibre 31 and spiral fiber is made to be formed by same group of yarn fibers 4, because this can enable in axis
Fiber 31 be laid with after the completion of without staple fibre yarn 4 can continuous winding screw fiber, twine silk head 6 etc. without replacement
Tool, to have higher manufacture efficiency.It is alternatively possible to twining silk head 6 using same group winds the first circumferential fibers 32 and the
Two circumferential fibers 33.
It is just as described above, it cannot be there are gap, to keep away between fiber composite layer 3 and supervisor 1 and pipe connections 2
Exempt from the intensity of influence delivery pipe, the peripheral dimension of the main part of pipe connections 2 is typically larger than the peripheral dimension of supervisor 1, the ruler
Very little drop is easy to above-mentioned gap be caused to generate (during especially winding screw fiber) in setting fiber composite layer 3.Therefore,
The circumferential surface of pipe connections 2 should slowly be transitioned into supervisor 1 close to the end of supervisor 1.For this purpose, consider above-mentioned helical angle size,
And combine Fig. 2 to Fig. 3 g, in a kind of delivery pipe of preferred embodiment, the end peripheral surface of the close supervisor 1 of pipe connections 2
Be formed as edge towards the tapered circular cone table top in the direction of the supervisor 1, and the taper of the circular cone table top is 1:5.8~1:1.3, so as to
So that the pipe connections 2 are slowly varying with about 5 °~20 ° of the gradient, until having at the port towards supervisor 1 with being responsible for 1 phase
Same outer radial dimension.So as to, on the one hand, lock axial direction fibre 31 and with prestressed in the first circumferential fibers 32
In the case of, it still is able to conveniently set up the second circumferential fibers 31, in order in the case where not making 31 transition of axial direction fibre tight
Appropriate prestressing force is provided；On the other hand, even if spiral fiber is wound with larger helical angle, also can after winding with Guan Lian
Fitting 2 (practical to be and the axial direction fibre 31 on the pipe connections 2) good fit, so that delivery pipe has good explosion-proof
Energy.
In illustrated preferred embodiment, pipe connections 2 are formed as a kind of rotary structure, with good manufacture work
Skill (as being convenient for turnery processing).In order to form the groove 21 for winding the first circumferential fibers 32, the peripheral surface of the pipe connections 2
On be formed with axially disposed multiple stage portions 22, so as to, between adjacent stage portion 22 formed groove 21.It is appreciated that
It is, as long as the size formed on the peripheral surface of pipe connections 2 changes and can form the Step-edge Junction of the groove 21
Structure, all can be stage portion 22 of the present invention.In the preferred embodiment, the separate supervisor of at least two stage portions 22
1 side is provided with the first circumferential fibers 32, to provide enough axial bonding strengths.In the present invention, although set up axial direction
Fiber 31 can make it greatly axially play tensile resistance, but the fixed form only locked by the first circumferential fibers 32 can
It can be difficult to reliably connect pipe connections 2 and supervisor 1.For example, under larger responsive to axial force, it is circumferential to may result in first
Fiber 32 causes pipe connections 2 to come off the lockout failure of axial direction fibre 31.By setting multiple grooves 21 and multiple tracks
One circumferential fibers 32, the connected deficiency of axial direction that the initial purpose of the acquisition present invention can be avoided to and may be brought.
Further, each stage portion 32 is respectively truncated cone and is arranged in order in an axial direction in pipe connections 2
On peripheral surface (stage portion 32 of i.e. each truncated cone is end to end), and the big end of the truncated cone is directed away from the one of supervisor 1
Side.During the first circumferential fibers 32 are wound, the problems such as due to performance accuracy, the first circumferential fibers 32 of initial wrap are difficult to
It falls in the bottom end of groove 21 (the large and small end joint of i.e. adjacent truncated cone), it is impossible to positive lock axial direction fibre 31, the axial direction
Prestressing force on fiber 31 can also reduce or disappear with the slip of the first circumferential fibers 32 in an axial direction.And above-mentioned preferred structure is just
In by applying certain pulling force (such as on following second fiber yarns 42) when winding the first circumferential fibers 32, so as to make
First circumferential fibers 32 are fallen in 21 bottom end of groove, and are resisted against on the large end face of truncated cone, with positive lock axial direction fibre 31
And the prestressing force on the axial direction fibre 31 is avoided to reduce.
A kind of structure of delivery pipe to being provided using manufacturing method of the present invention is illustrated above, above-mentioned delivery pipe
Each structure feature can be used in the appropriate case in the manufacturing method of subsequent tube-like piece.On this basis, it can also carry
For a kind of transport system, which includes multiple above-mentioned delivery pipes, and multiple delivery pipe is right successively by pipe connections 2
