Description
Technical field
The utility model relates to a kind of inner support annulus more particularly to a kind of correction and the inner support annulus for preventing barrel distortion.
Background technique
The relatively thin pressure container cylinder of wall thickness is in assembly, handling, welding, the influence for being heat-treated self gravity in addition, such as
Certain measure cylinder is not taken to be easy to generate biggish deformation, especially for the big cylinder of thin-walled, diameter, it is easier to go out
The problems such as existing cylinder recess, ovality increase, generates large effect to subsequent manufacture.Once there is cylinder recess, ellipse
Overproof problem is spent, the correcting process very complicated for meeting the requirements cylinder can greatly increase manufacturing cost and extend manufacture week
Phase.Pressure container cylinder relatively thin for such wall thickness should have corresponding device to carry out correction after molding to shell rolling simultaneously
Cylinder is prevented to be deformed in assembly, handling, welding, heat treatment process.
Summary of the invention
Technical problem to be solved by the utility model is: a kind of inner support annulus corrected and prevent barrel distortion is provided,
Solve the problems, such as that the relatively thin pressure container cylinder of wall thickness is easy to produce moderate finite deformation.
In order to solve the above-mentioned technical problem, the technical solution of the utility model there is provided a kind of correction and prevents cylinder from becoming
The inner support annulus of shape, which is characterized in that including annulus, the outer diameter of annulus and the internal diameter of cylinder are consistent, and annulus is by two semi-ring groups
At, be fixedly connected between two semi-rings by pressing plate, be all provided between the both ends of two semi-rings it is jagged, indentation, there be equipped with for supportting
Pushing away for being corrected tightly and to cylinder and fix by annulus is pulled pin.
Preferably, 1~8 deformation opening and 2~4 connecting holes are equipped on each semi-ring of the annulus.
Preferably, the pressing plate is equipped with and the homogeneous matched connecting hole of the connection hole site sum number amount on annulus.
Preferably, it is fixedly connected between the pressing plate and annulus by bolt, nuts and washers.
Preferably, the annulus with a thickness of 10~160mm, the ring width of annulus is 50~800mm.
Preferably, the pressing plate with a thickness of 5~80mm.
It is preferably, described that push away the two sides angle pulled pin consistent with the Notch angle of annulus.
Preferably, the consistency of thickness for pushing away the thickness and annulus pulled pin, pushing away the two sides angle pulled pin is 3 °~30 °.
Preferably, the two sides of the notch between two semi-rings are equipped with pressing plate.
It is met the requirements using the circularity that the inner support annulus of the utility model can effectively correct thin-wall barrel, and can be effective
Cylinder is prevented to be deformed in assembly, handling, welding, heat treatment process.The correcting process for meeting the requirements cylinder is relatively simple
It is single, it reduces manufacturing cost and shortens the manufacturing cycle.The inner support annulus of the utility model is divided to two valves, is easily installed, removes and repeats
It utilizes.

Specific embodiment
To be clearer and more comprehensible the utility model, hereby with preferred embodiment, and attached drawing is cooperated to be described in detail below.
The utility model is a kind of correction and prevents the inner support annulus of barrel distortion, as Figure 1-Figure 4, by annulus 1,
Pressing plate 2 pushes away 3, bolt of pulling pin, nuts and washers composition.Annulus 1 is divided to for two valves, i.e., is made of two semi-rings, the outer diameter of annulus 1
It is consistent with the internal diameter of cylinder 4,1~8 deformation 6 and 2~4 connecting hole of opening is set on each semi-ring of annulus 1.According to cylinder
4 wall thickness and diameter, plate thickness used in annulus 1 are 10~160mm, and the ring width of annulus 1 is 50~800mm (such as Fig. 1 institute
Show)；
Connected between two semi-rings by pressing plate 2, pressing plate 2 with a thickness of 5~80mm, pressing plate 2 be equipped with on annulus 1
Hole site sum number amount homogeneously matched connecting hole is connected, is fixed by bolt, nuts and washers (as schemed between pressing plate 2 and annulus 1
Shown in 1)；
Be all provided between the both ends of two semi-rings of annulus 1 it is jagged, push away pull pin 3 be set to annulus 1 two semi-rings and two
Indentation, there between pressing plate 2 is corrected and fixes to cylinder 4 for stretching and by annulus 1, push away pull pin 3 thickness and circle
The consistency of thickness of ring 1, pushing away the 3 two sides angle of pulling pin is 3 °~30 °, and consistent with the Notch angle of annulus 1 (as shown in Figure 1).
As shown in figure 4, utilizing the circularity and steel of the stretching and combination annulus 1 that push away 3 gradients of pulling pin when assembly inner support annulus
Property, so that 4 internal diameter of cylinder is reached unanimity with 1 outer diameter of annulus, to achieve the purpose that correct cylinder roundness and prevent barrel distortion.Cylinder
For body 4 after the weldering of roll-forming longitudinal joint is appropriate, the inner support annulus 5 of 4 liang of properly installed the utility model in circumferential weld end of cylinder can correct the circle of cylinder
