Background technology
Flagpole, as the modal outdoor facilities of daily life, spreads all over factory, school and Party and government offices.She is a kind of propagandizing form of showing national image and enterprises and institutions' cultural traits.
At present, most outdoor flagpoles are manufactured by pure stainless steel tube welding, not only high expensive, and because pure stainless steel tube wall thickness, bending strength are low, after month after month exposing to wind and rain, just flexural deformation even fractures gradually throughout the year, not only have a strong impact on country and enterprises and institutions' image, also easily caused contingency.
Summary of the invention
Problem to be solved by this invention is to provide a kind of stainless steel composite pipe material and safe welding technique, manufacture and design the compound flagpole of a kind of high-strength stainless steel, can reduce flagpole manufacturing cost, can increase substantially again bending strength, keep flagpole durable in use, indeformable, not bending, do not fracture.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is:
1, material is selected:
Take Q235 cold rolled precision welded tube as base tube, outer multiple 304 stainless-steel thin-wall pipes, are manufactured and are become high-strength stainless steel pipe (hereinafter to be referred as stainless steel composite pipe) by the axial cold-drawn of wolfram steel mould by cold drawing tube machine.
The stainless steel composite pipe that described flagpole uses, its specification is respectively:
Epimere: external diameter ￠ 89mm, wall thickness 2.5 mm (wherein 304 stainless steel tube wall thickness 0.5mm, cold rolled precision welded tube wall thickness 2.0mm), length: 3 meters.
Stage casing: external diameter ￠ 102mm, wall thickness 3.0 mm (wherein 304 stainless steel tube wall thickness 0.8mm, cold rolled precision welded tube wall thickness 2.2mm), length: 3 meters.
Hypomere: external diameter ￠ 127mm, wall thickness 4.0 mm (wherein 304 stainless steel tube wall thickness 1.0mm, cold rolled precision welded tube wall thickness 3.0mm), length: 6 meters.
2, welding:
The stainless steel composite pipe that flagpole is used, arranges along horizontal axis direction by upper, middle and lower segment.
First epimere stainless steel composite pipe is injected in stage casing stainless steel composite pipe to approximately 100～150mm, evenly fixing with steel plate bar around, definitely guarantee epimere after fixing and stage casing stainless steel composite pipe central axis point-blank.
Put in stage casing stainless steel composite pipe with common straightcarbon steel basic electrode, epimere is injected in the pipe of stage casing approximately to the stainless steel composite pipe of 100～150mm and stage casing inwall and steel plate bar is welded together.
By pure stainless steel reducer pipe, (one end internal diameter is equal to epimere stainless steel composite pipe external diameter again; other end internal diameter is equal to stage casing stainless steel composite pipe external diameter); one end cover is multiple around epimere stainless steel composite pipe; one end is connected with the stage casing stainless steel composite pipe mouth of pipe, then uses 304 pure stainless steel electrodes uniform welding, reconditioning, polishing under argon shield.
The stage casing stainless steel composite pipe that has welded epimere is injected in hypomere stainless steel composite pipe to approximately 100～150mm, repeat above-mentioned steps, complete welding, reconditioning, the polishing of whole flagpole upper, middle and lower segment stainless steel composite pipe.
The required annex of flagpole, comprises heading, wax rope, pulley etc., by flagpole designing requirement buying and installation.
The invention has the beneficial effects as follows, can reduce manufacturing cost, can increase substantially again bending strength, keep flagpole durable in use, indeformable, not bending, do not fracture.
