Description
Technical field
The present invention relates to pipe machining equipment, is a kind of hot-melting fixture manufacturing multiple tube for metal tube plastic lining.
Background technology
Pipeline transportation be with pipeline as the means of transportation of a kind of long distance delivery liquids and gases goods and materials of means of transport, have freight volume large, take up an area less, the pipeline transportation construction period is short, expense is low, pipeline transportation is safe and reliable, continuity is strong, pipeline transportation consumes energy less, cost is low, profitable advantage.Pipe is the main member forming pipeline, pipe has steel pipe by material, cast iron pipe, concrete reinforced pipe, non-metallic pipe is several, multiple tube is the chemical building material pipeline of a new generation, especially steel-plastics composite pipe, compared with traditional composite metal plastic pipe or plastic conduit, the high strength of existing steel pipe, stretching resistance, the creep resisting advantage of low-expansion coefficient, there is again the extra-strong corrosion resistant of plastic tube, the smooth non-scaling of tube wall, the feature that fluid resistance is little, and be embedded in underground and can seek track with magnetic-metal detector, bear external pressure ability to stablize, its service life is considerably beyond steel pipe and plastic tube.Exploitation, the production of steel-plastics composite pipe production line have good economic benefit and social benefit.
At present, the multiple tube that state inner metal tube plastic lining is produced is metal tube and plastic tube with heating in medium frequency mode hot melt compound, due to aperture > φ 200mm, the multiple tube size of length > 7m is large, length is long, heating in medium frequency carries out hot melt compound tense, gas between metal tube and the plastic tube of liner is not easily discharged, therefore, easily because gas interlayer produces the Separation phenomenon of freestone bulge between the plastic tube of liner and metal tube, have a strong impact on the quality that metal tube plastic lining manufactures multiple tube, reduce service life.
Summary of the invention
Technical problem to be solved by this invention is: the shortcoming overcoming prior art, provides that a kind of structure is simple, easy to operate, hot melt is effective, repair demolition is quick, the hot-melting fixture manufacturing multiple tube for metal tube plastic lining of long service life.
The scheme of technical solution problem of the present invention is: a kind of hot melt exhaust fixture manufacturing multiple tube for metal tube plastic lining, it is characterized in that: it comprises core body, overcoat, exhaust ring and breather pipe, described core body cylinder is identical with the hole size of inner lining plastic tube, the hydraulic cylinder piston rod that the outer end of core body and fuse machine support are arranged is connected, core body axially arranges passage, described overcoat inner surface is identical with the exterior surface dimension of inner lining plastic tube, overcoat and core body are connected and outer end shutoff, overcoat inner surface and core body cylinder form the cannelure of axially open, described exhaust ring is the annular ring along arranging several steam vents week, exhaust ring and overcoat are tightly connected, breather pipe one end is communicated with in inner lining plastic tube by the passage of core body, the other end is communicated with air compressor machine, switch and Pressure gauge are set between breather pipe and air compressor machine.
In the cannelure that described overcoat inner surface and core body cylinder are formed, sealing ring is set.
Using method of the present invention is:
1) fixture of the present invention is installed
First be placed on fuse machine by fixture of the present invention, core body and hydraulic cylinder piston rod are connected, and breather pipe is tightly connected with the passage of core body and air compressor machine, switch and Pressure gauge respectively;
2) on fuse machine, hot melt is carried out
The metal tube installing inner lining plastic tube is placed on workbench by a, is started the carriage member of clamping device, make the metal tube having installed inner lining plastic tube coaxial with hydraulic cylinder by operating desk;
B sprays releasing agent on the fixture and bellmouth mould of invention;
C drives hydraulic cylinder by hydraulic control device, and drive fixture of the present invention and bellmouth mould to clamp at socket and bellmouth two ends the metal tube having installed inner lining plastic tube, by switch control rule, be inner lining plastic tube inner inflatable by breather pipe simultaneously;
D opening operation platform walking switch and starting power regulate and start heating, and the metal tube having installed inner lining plastic tube enters intermediate frequency heater heating hot melt, and meanwhile, the gas that hot melt produces is discharged, until complete hot melt by the steam vent of exhaust ring.
The beneficial effect that the present invention is used for the hot-melting fixture of metal tube plastic lining manufacture multiple tube is: breather pipe of the present invention can ensure that inner lining plastic tube inside has certain air pressure, make the better hot-melt adhesive of inner lining plastic tube on metal tube, gas during heating between inner lining plastic tube and metal tube can be discharged in time by the steam vent of exhaust ring, avoid between the plastic tube of liner and metal tube easily because gas interlayer produces the Separation phenomenon of freestone bulge, improve quality and service life that metal tube plastic lining manufactures multiple tube, there is structure simple, easy to operate, hot melt is effective, repair demolition is quick, the advantage of long service life.
