Description
Technical field
The invention belongs to pressure vessel field shaping technique more particularly to a kind of composite L PG gas cylinders moulding process and
Device.
Background technology
Currently, liquefied petroleum gas cylinder available on the market is steel material, welding structure.Such as CN104972014A public affairs
A kind of moulding process and device of liquefied gas bottle are opened, molding steel cylinder is cumbersome with manufacturing procedure, quality is big and transports not
Just, perishable, do not have the defects of visual, service life is short and inspection cost is high, have explosion accident generation using intermediate frequency.Steel
The liquefied petroleum gas cylinder of matter can cause prodigious destructive power once bursting under high-pressure situations.Composite L PG gas cylinders are with it
It is light-weight, intensity is high, it is corrosion-resistant, do not explode, be see-through, service life is long, maintenance cost is low etc., and that excellent properties replace is traditional
Metal cylinder has broad application prospects.
CN103196031A discloses high molecular material welding liner filament wound composite gas cylinder and its manufacture
Method, it is relative complex and apply macromolecule welding equipment that cylindrical metal connector is moulded in the technique inside high molecular material
Liner is formed, however the influence factor of macromolecule welding procedure is more and elapsed time is long, oval tubular body and semicircle
Spherical moulding is that three-stage structure is welded into an entirety, it may appear that weld uneven surface and structural stress is non-uniform
Situation.
CN1196462A discloses compressed natural gas used as vehicle fuel composites gas cylinder and its manufacturing method, first, plastic inner container
Using rolling technique, shaping efficiency is poor compared with blow molding process and needs trepanning process, and secondly, winding process is twined using wet method
Around, compared with dry fibers wind speed difference, can cause glue waste and processing environment it is unclean, finally, production gas cylinder needs cover
External protection processed influences entire production efficiency and can not observe fluid change in bottle.
Invention content
For overcome the deficiencies in the prior art, a kind of composite L PG gas cylinders moulding process of present invention offer and device, production
Product good airproof performance, easily manufactured, light weight, service life is long, security reliability higher.
The technical solution adopted by the present invention to solve the technical problems is：
A kind of composite L PG gas cylinder moulding process, first blowing use bottleneck and body integration blow molding method
Liner, processing is carried out to the extra material of liner and forms the smooth liner in surface, to portions such as bottleneck mounting flange, valve seat, sealing rings
Part carries out liner using wrapping machine the high-speed coiling of reinforcing fiber layer, installs valve, Wrapping formed gas cylinder is put into injecting glue
Station, gel-injection mould is combined and seals, and the pressurization that glue is carried out by adhesive pouring nozzle is injected, and glue is enable to infiltrate through fibre
Each filament surface for tieing up layer keeps the internal pressure of liner to be consistently higher than the hydraulic pressure of gum-injecting port interior to prevent while injecting glue
The deformation of courage and fibrous layer；By heating and cool down curing molding of the mold realization to glue, finally adding handle, foot ring and preventing
Sheath.
The present invention is also realized by following measure：The blow mold of blowing device is the structure that surplus is blow molded with bottleneck,
Realize the integrated blow molding of bottleneck and body.The injecting glue shell of glue filling device is two-part structure, and connects bottleneck one end
Gel-injection mould be to be subject to distribution adhesive pouring nozzle and connection glue injection pipe on the separated symmetrical structure of busbar and mold, i.e., by gas cylinder
Be put into mold process, the symmetrical two parts of upper section die clamped into the sealing ring on the narrow flange of bottle mouth position first, then will under
Section die carries out Butt sealing with upper section die, and there are 2-5 millimeters of spatial margins between mold internal layer and gas cylinder.
The invention has the advantages that plastic inner container and the integral structure that bottleneck is a blow molding, save valve opening
Trepanning is processed；Aramid fiber is substituted using glass fibre, reduces cost；Dry fibers winding is more efficient；Seal pouring adds
Work cleans, and saves glue, and conveying is convenient；Using glue as protective layer, moulded products visuality is good, is able to observe that liquid level
Highly；Product hermeticity is good, easily manufactured, and light weight, service life is long, security reliability higher.
