Description
Technical field
The present invention relates to a kind of matching used fiber fw frps of the fields such as petrochemical industry, municipal administration GRP pipe
Equipment and manufacturing process is made in pipe fitting manufacturing equipment and technique, more particularly to a kind of fiber fw frp pipe fitting.
Background technology
Matching component of the pipe fitting as a kind of indispensability of pipeline, quality are directly related to the fortune of entire pipe network system
Row safety, and the tubing products that GRP pipe field is applied at present, are manual Wrapping formed, generally existing production efficiency
It low, the problems such as production technology is backward, quality is unstable, especially the epoxy tubing products of high pressure grade, will to product quality
Ask very high, but existing hidden danger of quality problem is also than more prominent.It is mainly manifested in：
1st, low production efficiency.Artificial winding moulding process makes pipe fitting, needs that multiple processes are mutually coordinated, and lay-up process is multiple
It is miscellaneous to cause preparatory process required time very long；Simultaneously as the limitation in terms of manual operation physical efficiency, can not realize high-caliber
Quick winding, production efficiency is relatively low, required artificial more, especially high-volume continuous production when this aspect it is restricted bigger.
2nd, quality is unstable.Artificial winding moulding process makes pipe fitting and ensures product quality, winding process by feel entirely
In the factors such as tension force, alignment control change very big, operation technique, qualification between employee etc. can be to product matter
Amount causes very big influence, can not realize proper standardized production, quality stability is poor.
3rd, product ply angles are unreasonable, poor mechanical property.Artificial winding moulding process makes pipe fitting, due to equipment, mould
The limitation of tool and technique, to make the not sliding yarn of silvalin in winding process, ensureing product axial strength, product uses " glass fibers
The interlayer structure of dimension yarn+Multiaxial Fiberglass Fabrics " carries out alternately winding, and tension is different between two different materials, interlayer
Shear strength is low, it is easy to generate the pipe fitting that the mass defects such as layering, aerial and artificial winding moulding process make and often go out
Existing quality problems.
4th, presentation quality is poor.The pipe fitting that artificial winding moulding process makes due to tension force is uneven, linear disorder etc. because
Element, product curing molding process in which materials, which crosslinks reaction, to be expanded, and cause product surface out-of-flatness smooth, subsequently need through
A large amount of manual polishing is crossed to modify product surface.
5th, production cost is high.With higher and higher, the people needed for artificial winding moulding process making pipe fitting of cost of labor
Work cost is higher and higher, especially skilled operative employee, and since technical threshold is higher, when staff training and skills training
Between it is long；During high-volume continuous production, the production efficiency and cost of labor of tubing products have become maximum obstruction.

At 120-150 DEG C, hardening time is not less than 1h, depending on products thickness；
（6）Cooled down after the completion of curing, finishing demoulding carried out when being cooled to less than 50 DEG C, and complete the cleaning of mold with
Assembling is with spare.
In addition, it is necessary to what is further described is：Pivoted arm（7）, manipulator（2）And Wound Dies（5）The course of work it is as follows：
（a）Glass fiber yarn and glass fabric by arrangement pass through strainer（8）Coiling fixture is passed through afterwards（6）'s
Bootstrap block（6.8）, one end is clamped in pivoted arm（7）On pneumatic chuck（22）On；Pneumatic chuck（22）It is carried out using self-locking cylinder
Folding control, pivoted arm（7）Clutch air cylinder when rotating to fixed position（21）Clutch block is pushed to connect pneumatic circuit, drives self-locking gas
Cylinder is so as to make pneumatic chuck（22）Opening and closing；Pressure test device in pneumatic circuit is installed, detects clutch circuit and self-locking cylinder
Conjunction state；Pivoted arm（7）The radius of gyration can be according to Wound Dies（5）The radius of gyration be adjusted；
（b）When winding starts, pivoted arm servo motor（16）Drive pivoted arm（7）It is rotated by 90 ° counterclockwise；Pivoted arm（7）By level
When state is rotated by 90 ° counterclockwise to plumbness, spindle servo electric machine（15）Driving spindle（13）Driven mold（5）With pivoted arm
Synchronous rotary；Pivoted arm（7）And mold（5）It synchronizes and continues to rotate, work as pivoted arm（7）When occurring dry and astringent with fibrous material, coiling fixture
（6）Fibrous material is driven to be avoided by the driving of manipulator；Manipulator（2）Coordinate pivoted arm（7）And mold（5）Synchronous rotary
After 2 weeks, and in pivoted arm（7）Stop position stops operating, and fibrous material has been wound to mold at this time（5）On, clutch air cylinder（21）
Act pneumatic chuck（22）Opening decontrols pivoted arm after fibrous material（7）To position is waited for, process of starting is completed for rotation；
（c）Formal winding starts spindle servo electric machine（15）Driving spindle（13）Driven mold（5）Start to rotate, twine simultaneously
Around fixture（6）In manipulator（2）Drive under slowly close to mold（5）, until compact heap（6.6）Silvalin is pressed on mold
（5）：Manipulator（2）With spindle servo electric machine（15）Into loop synchronizer, mold is driven（5）Rotate simultaneously wound fixture
（6）Compress silvalin, and keep it is vertical with mold normal plane, silvalin it is progressive be wound to mold from level to level（5）Surface；It twines
Around while, adjust tension mechanism（8）Spacer pin, fiber yarn tension is made to be in OK range；And pass through adjusting nut
（6.2）Adjust compact heap（6.6）Pressing force on mold carries out the secondary adjustment of fiber yarn tension；Compact heap（6.8）With draw
Guide block（6.8）It can be replaced because of winding process difference, can quickly remove and be cleared up after the completion of winding, replacing with acknowledgment copy makes
With；
（d）By coiling fixture（6）Fixture housing（6.5）It removes, fixture main shaft（6.1）Leading portion position is machined with calibration top
Needle（6.10）With dismountable dial indicator holder（6.9）And dial gauge（6.11）, for the calibration use of manipulator programming.
The beneficial effects of the invention are as follows：Product is programmed using glass fibre and epoxy resin as main raw material(s) through computer
It automatically controls and prepares；Due to automatically controlling operation using manipulator, the running orbit of fiber in the production process is opposite
In artificial winding, either have in terms of precision or speed and significantly promoted, and can realize that glass fiber yarn is small
Angle wound improves product axial strength.For old manual winding process since glass fiber yarn winding angle is big, product is axial
Intensity difference, it is necessary to increase multiaxial fabric or other glass fabrics to improve product axial strength, but bring another ask
Topic precisely due to the difference of reinforcing material and cause product interlaminar shear strength it is poor, easily be layered.And that product can be achieved is pure for the invention
Silvalin is Wrapping formed, solves the above problem well.
