Abstract
The invention discloses a kind of cylinder and hold round technique, comprise the following steps: a, making inner support annulus；Inner support annulus is made up of fagging in multiple arcs, and in arc, the thickness of fagging is 10 12mm, and width is 100 150mm；B, welding: arc holds round plate and is welded on cylinder inboard wall, it is to use to be interrupted to weld that arc holds round plate and barrel soldering, and arc holds round plate two side weld and must stagger simultaneously.The present invention has and can make full use of the splicing of clout plate and make internal stay tool, reduces cost；It is convenient for measuring；The effectiveness comparison held round is good；Owing to holding round the few with material of frock, delivery weight can be alleviated, such that it is able to the advantage saving cost of transportation.
Description
Technical field
The open a kind of cylinder of the present invention holds round technique.
Background technology
At present, the conventional method that cylinder holds round is to use cross hang to hold round, and this mode is only suitable for sky diameter less than the holding round of cylinder of 1500 when going, for the cylinder more than 1500, hold round poor effect, if inner support length obtains inaccurate, more can cause mistake circle.For the cylinder more than 1500, use rice word to hold round, although this mode adds the strong point on circumference, can effectively improve the problem losing circle, but materials are many, be the most also unfavorable for measuring carrying out of work.
Summary of the invention
The invention aims to overcome above deficiency, it is provided that a kind of tool structure is simple, easily operation, to the measurement of finished product and strengthened attractive in appearance, frock material is less, and the cylinder that can reduce material cost and cost of transportation holds round technique.
The purpose of the present invention is achieved through the following technical solutions: a kind of cylinder holds round technique, comprises the following steps: a, making inner support annulus；Inner support annulus is made up of fagging in multiple arcs, and in arc, the thickness of fagging is 10-12mm, and width is 100-150mm；B, welding: arc is held round plate and is welded on cylinder inboard wall, arc holding round plate with barrel soldering is to use to be interrupted to weld, arc holds round plate two side weld and must stagger simultaneously, during welding, uses manual gas shield welding, leg height is less than or equal to 0.7 times of thickness of slab, fusion length is less than the discontinuity length of weld seam, according to cylinder inboard wall diameter, determines the number of fagging in arc, when in inner support annulus is by two pieces of arcs, fagging is spliced, in every piece of arc, the radian of fagging should be less than semicircle；When in inner support annulus is by three pieces of arcs, fagging is spliced, the radian of every piece is 150-160 degree；Allowing three during assembling mutually to stagger, when in inner support annulus is by four pieces of arcs, fagging is spliced, the radian of every piece is 100-120 degree, allows three and mutually stagger, by that analogy during assembling.
The present invention can make full use of the splicing of clout plate and make internal stay tool, reduces cost；It is convenient for measuring；The effectiveness comparison held round is good；Owing to holding round the few with material of frock, delivery weight can be alleviated, such that it is able to save cost of transportation；Better appearance.
Detailed description of the invention:
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, and this embodiment is only used for explaining the present invention, is not intended that limiting the scope of the present invention.
A kind of cylinder of the present invention holds round the detailed description of the invention of technique, comprises the following steps: a, making inner support annulus；Inner support annulus is made up of fagging in multiple arcs, and in arc, the thickness of fagging is 10-12mm, and width is 100-150mm；B, welding: arc is held round plate and is welded on cylinder inboard wall, arc holding round plate with barrel soldering is to use to be interrupted to weld, arc holds round plate two side weld and must stagger simultaneously, during welding, uses manual gas shield welding, leg height is less than or equal to 0.7 times of thickness of slab, fusion length is less than the discontinuity length of weld seam, according to cylinder inboard wall diameter, determines the number of fagging in arc, when in inner support annulus is by two pieces of arcs, fagging is spliced, in every piece of arc, the radian of fagging should be less than semicircle；When in inner support annulus is by three pieces of arcs, fagging is spliced, the radian of every piece is 150-160 degree；Allowing three during assembling mutually to stagger, when in inner support annulus is by four pieces of arcs, fagging is spliced, the radian of every piece is 100-120 degree, allows three and mutually stagger, by that analogy during assembling.
The present invention can make full use of the splicing of clout plate and make internal stay tool, reduces cost；It is convenient for measuring；The effectiveness comparison held round is good；Owing to holding round the few with material of frock, delivery weight can be alleviated, such that it is able to save cost of transportation；Better appearance.
