Description
Technical field
The present invention relates to field GRP pipe matching used Filament-wound Machine fiberglass pipe fitting manufacturing equipment and the techniques such as a kind of petrochemical industry, municipal administration, particularly a kind of equipment of making of Filament-wound Machine fiberglass pipe fitting and manufacturing process.
Background technology
Pipe fitting is as the matching component of a kind of indispensability of pipeline, its quality is directly connected to the security of operation of whole pipe network system, and the tubing products that current GRP pipe field is applied, be manual Wrapping formed, the problems such as ubiquity production efficiency is low, production technology is backward, quality is unstable, especially the epoxy tubing products of high pressure grade, requires very high to product quality, but the hidden danger of quality problem existed is also more outstanding.Be mainly manifested in:
1, production efficiency is low.False twist's moulding process makes pipe fitting, and need multiple operation mutually to coordinate, lay-up process complexity causes preparatory process required time very long; Meanwhile, due to the limitation of manual operation physical efficiency aspect, cannot realize high-caliber quick winding, production efficiency is lower, required manually more, and during continuous seepage especially in enormous quantities, this aspect is restricted larger.
2, quality is unstable.False twist's moulding process makes the full armrest sense of pipe fitting and ensures product quality, the factor such as tension force control, alignment control variation in winding process is very large, operation technique between employee, qualification etc. all can cause very large impact to product quality, cannot realize proper standardized production, quality stability is poor.
3, product ply angles is unreasonable, poor mechanical property.False twist's moulding process makes pipe fitting, due to the limitation of equipment, mould and technique, for making the not sliding yarn of silvalin in winding process, ensureing product axial strength, product adopts the sandwich structure of " glass fiber yarn+Multiaxial Fiberglass Fabrics " to carry out alternately being wound around, between two kinds of different materials, tension force is different, interlaminar shear strength is low, and being easy to mass defects such as producing layering, make somebody a mere figurehead, is also the quality problems that the pipe fitting of false twist's moulding process making often occurs.
4, presentation quality is poor.The pipe fitting that false twist's moulding process makes controls the factors such as inequality, linear disorder due to tension force, in products solidifying forming process, material cross-links reaction can be expanded, cause product surface out-of-flatness smooth, follow-uply to need through a large amount of manual polishings to repair product surface.
5, production cost is high.More and more higher along with cost of labor, the cost of labor that false twist's moulding process makes needed for pipe fitting is more and more higher, especially skilled operative employee, and due to technical threshold higher, staff training and the skills training time long; During continuous seepage in enormous quantities, the production efficiency of tubing products and cost of labor have become maximum obstruction.

(4) carry out orientation winding 3-5 circle when manually connecing yarn to come off to being wound around the sliding yarn of yarn, startup automatic winding pattern, requires automatically to be wound around according to Lay up design;
(5), after tube manufacture completes, mould and Total Product are put into baking oven and carries out heating cure, heating and temperature control is at 120-150 DEG C, and hardening time is not less than 1h, determines according to products thickness;
(6) cool after having solidified, when being cooled to below 50 DEG C, carry out the finishing demoulding, and complete the cleaning of mould and assemble with for subsequent use.
In addition, need to further describe: the course of work of pivoted arm (7), manipulator (2) and Wound Dies (5) is as follows:
(a) through the glass fiber yarn that arrangement and glass fabric by after strainer (8) through the bootstrap block (6.8) being wound around fixture (6), one end is clamped on the pneumatic chuck (22) on pivoted arm (7); Pneumatic chuck (22) adopts self-locking cylinder to carry out folding control, and when pivoted arm (7) rotates to fixed position, clutch air cylinder (21) promotes clutch block and connects pneumatic circuit, drives self-locking cylinder thus makes pneumatic chuck (22) opening and closing; In pneumatic circuit, pressure test device is installed, detects clutch loop and self-locking cylinder opening and closing state; Pivoted arm (7) radius of gyration can regulate according to the radius of gyration of Wound Dies (5);
When () is wound around and starts b, pivoted arm servomotor (16) drives pivoted arm (7) to be rotated counterclockwise 90 degree; Pivoted arm (7) by level be rotated counterclockwise 90 degree to plumbness time, spindle servo electric machine (15) drive shaft (13) driven mold (5) and pivoted arm synchronous rotary; Pivoted arm (7) and mould (5) synchronously continue to rotate, and when pivoted arm (7) occurs dry and astringent with fibrous material, are wound around fixture (6) and are dodged by the rotating band kinetodesma material of manipulator; Manipulator (2) coordinates pivoted arm (7) and mould (5) synchronous rotary after 2 weeks, and stop operating at pivoted arm (7) stop position, now fibrous material has been wound on mould (5), after relieving fibrous material opened by clutch air cylinder (21) action pneumatic chuck (22), pivoted arm (7) rotates to waiting for position, and operation of starting completes;
C () is formally wound around beginning spindle servo electric machine (15) drive shaft (13) driven mold (5) and starts to rotate, be wound around fixture (6) under the drive of manipulator (2) slowly near mould (5) simultaneously, until silvalin is pressed on mould (5) by compact heap (6.6): manipulator (2) and spindle servo electric machine (15) enter loop synchronizer, drive mould (5) to rotate and be wound around fixture (6) compression silvalin simultaneously, and keep vertical with mould normal plane, what silvalin was laddering is wound to mould (5) surface from level to level; While being wound around, the spacer pin of adjustment of tonicity mechanism (8), makes silvalin tension force be in OK range; And by adjusting nut (6.2) adjustment compact heap (6.6) thrust on mould, carry out the secondary adjustment of silvalin tension force; Compact heap (6.8) can be changed because winding process is different with bootstrap block (6.8), can clear up, be used alternatingly with acknowledgment copy after being wound around under fast dismantling;
D the fixture overcoat (6.5) being wound around fixture (6) is pulled down by (), fixture main shaft (6.1) leading portion position is processed with calibration thimble (6.10) and dismountable dial indicator holder (6.9) and dial gauge (6.11), for the calibration use that manipulator is programmed.
The invention has the beneficial effects as follows: product is with glass fibre and epoxy resin for main raw material(s), and machine programming nonstick system of control is standby as calculated forms; Owing to adopting the automatic control operation of manipulator, the running orbit of its fiber in manufacturing process is relative to false twist, be all had significantly to promote in precision or speed, and the winding of glass fiber yarn low-angle can be realized, improve product axial strength.Old manual winding process due to glass fiber yarn winding angle large, product axial strength is poor, must increase multiaxial fabric or other glass fabric to improve product axial strength, but another problem brought is exactly cause due to the difference of reinforcing material that product interlaminar shear strength is poor, easily layering.And this invention can to realize the pure silvalin of product Wrapping formed, well solve the problems referred to above.
