Surname man, becomes the preferred fuels of urbanite.In these need the building of use pipe gas, civilian dark kitchen, open type
The gas safe in kitchen is especially prominent, and the appropriate design of the water pipe clean of this kind of building is seemed the most urgent and necessary.
Civilian dark kitchen, open type kitchen pipeline gas supply are complicated system engineerings, need gas company from
The many-sides such as design, construction, management, operation, service are strict with, and combine the ventilating system in kitchen, warning system
The many-sides such as system, required pipe part, the acceptance of work take appropriate measures, and I is implemented civilian dark kitchen, open type kitchen
The gas networks design in room is arranged particularly important, on the premise of guaranteeing design specification, and the workmanship of gas-fired kitchen pipeline
The most particularly significant.
Gas-fired kitchen pipeline uses steel pipe at present, and uses screwed connection, and general gas-fired kitchen pipeline is to secretly set, its
May be provided in the tube seat on wall or piping shaft, it is possible in being arranged on the couter-ceiling that non-combustible material is constituted or in pipe trench, the pipe secretly set
The tube seat on road should arrange dodge gate and vent, it is ensured that the safety of use.
For the gas-fired kitchen pipeline that each family is different designed by other, it needs to select various length steel pipe, but existing
When having technology to manufacture gas-fired kitchen pipeline, there is certain error in obtained fished pipe in length, causes and is arranging
During gas-fired kitchen pipeline, need pipe cutting again, reduce efficiency of construction, improve construction cost, also destroy steel pipe simultaneously
Original structure.
Summary of the invention
Present invention aim at solving above-mentioned technical problem present in prior art, it is provided that gas-fired kitchen pipeline manufactures
Technique, molding of being bored a hole by pipe obtains steel pipe, and cutting seam and cutter sweep that steel tube surface is arranged mutually adjust alignment, enter in batches

Bonding, then steel pipe is put in anticorrosive paint, steel pipe can be pulled after being totally submerged out, adhesive tape is torn, on steel pipe after dry
Stay one to cut seam clearly, again steel pipe is carried out preservative treatment.Then fixed length cutting is conducted batch-wise, by 5～10 steel pipes
It is passed on backing roll 11, the most mutual square of steel pipe, the phenomenon that steel pipe stacks must not occur.Control hold-down devices 12 more at the uniform velocity
Decline, steel pipe pushed down by pressure roller 15, in order to avoid pressure roller 15 leaves cut to steel tube surface, can before pressure roller 15 contacts with steel pipe,
Steel pipe is laid one layer of bed course.Then wash away emery wheel 7 with cooling-lubricant, be then turned on motor 4, control motor 4 rotating speed
2000～3000 revs/min, recycling positioner about 10 adjusts cutting bed 9, and cutting seam is quickly moved to the left side of emery wheel 7,
Then utilize positioner 10 to control cutting bed 9 the most at the uniform velocity to slide, often move 1cm and carry out position between emery wheel 7 and cutting seam
Alignment work, when emery wheel 7 and cutting seam consistency from top to bottom, uniform descent control panel 3, emery wheel 7 is fixed length cutting at cutting seam
Steel pipe, cutting speed controls at 1.2m/min.After the equal fixed length cutting of steel pipe, focus on waste material with hairbrush and rag.
After every batch of Steel pipe fixed length cutting, using shower nozzle that draw-in groove 8 is carried out clear water flushing work, shower nozzle is by the centre of draw-in groove 8
Position is sprayed to two ends, and spray angle keeps 10～30 °, then with rag, draw-in groove 8 is carried out wiping.
(i) steel pipe cutting part edge reconditioning: select burr removing device that the cutting part of steel pipe is carried out edge reconditioning,
The anterior angle of the cutting edge of cutter head being controlled at 20～30 °, relief angle controls, at 6～10 °, to use cutter head deburring.
(j) steel pipe second time inspection: steel pipe second time inspection is identical with the front three process inspection of inspection for the first time, increases
4th procedure inspection, carries out compression test to steel pipe sampling air pressure testing machine, and each pressing time continues 4～6min, when
After test pressure reaches 1.5MPa, keep voltage stabling control 10～12min, the resistance to compression situation of inspection outer wall of steel pipe.Steel pipe resistance to compression is surveyed
Examination pressure be above standard test pressure time, technical staff is negotiable determines other tolerance.
K () packs: to checking qualified steel pipe to stack respectively according to product material, specification, and do corresponding mark, then enter
Row packing work, then focuses on underproof steel pipe, recycles.
Qualified pipe is carried out pickling processes by the present invention, removes oxide skin and corrosion thing, the pickling processes on pipe surface
Rear surface cleaning light, is difficult to loss of gloss and fades, and not yellowing improves the quality of pipe；Pipe perforation molding obtains high-quality, high-strength
Degree steel pipe；The cut place of the steel pipe after surveying length is arranged cutting seam, is specially and sticks an adhesive tape in the cut place of steel pipe, and will
Adhesive tape is made in order, ending bonding, then is put into by steel pipe in anticorrosive paint, can pull steel pipe out, by glue after dry after being totally submerged
Band tears, so that it may stays one to cut seam clearly on steel pipe, so utilizes positioner 10 to control cutting bed 9 the most at the uniform velocity
Slide, often move 1cm and carry out position alignment work between emery wheel 7 and cutting seam so that emery wheel 7 and cutting seam consistency from top to bottom, then
Fixed length cutting is conducted batch-wise, and owing to steel pipe is clamped between backing roll 11 and pressure roller 15, in cutting process, steel pipe does not haves
Position shift phenomenon so that between length and the full-length of required steel pipe of the steel pipe after cutting deviation control 2mm with
In, improve cutting accuracy；To the edge reconditioning of steel pipe cutting part, remove the burr of cutting part, improve flatness；The most just may be used
