Description
Technical field
The utility model is related to bulging fields, and in particular to a kind of large ring bulging mechanism.
Background technology
Bulging is inside pipe or to pass to highly pressurised liquid, gas in slab side or be put into rigid body petal, forces pipe, plate
Plastic deformation, the process for stamping and forming of workpiece is made.In actual production, the expanding method of generally use mainly has rigid mould swollen
The methods of the bulging of shape, solid soft mode bulging, hydraulic expanding-forming, raising and cylinder type hollow blank.Wherein for big type ring
For part, the mode for mostly using hydraulic expanding-forming greatly in the prior art is processed.Hydraulic expanding-forming is shaped under no Frotteurism,
It is few deformation non-uniform phenomenon occur compared with other expanding methods.However the bulging equipment of large ring in the prior art,
Its structure is sufficiently complex, needs to realize the bulging to ring with commutating structure progress displacement using many sliding blocks.Especially
Be for diameter 3~10m, even diameter more than 10m ring for, existing bulging equipment be even more structure it is extremely complex,
Production is high with use cost and bulging efficiency is also universal low.
Utility model content
The purpose of this utility model is to provide a kind of large ring bulging mechanisms, to solve to be used for large size in the prior art
The problem of bulging device structure of ring is complicated, inefficiency, realize it is simple, bulging processing efficiently is carried out to large ring
Purpose.
The utility model is achieved through the following technical solutions：
A kind of large ring bulging mechanism, including supporter that outer surface is cylindrical, the support body sidewall is circumferentially
The groove of annular is set, the pouch of annular, flexible ring body are set in the groove, the expansion ring body is located at the outside of pouch,
Inlet tube, exhaust pipe are connected in the pouch.
The problem of for bulging device structure complexity, the inefficiency for being used for large ring in the prior art, this practicality is new
Type proposes a kind of large ring bulging mechanism, and the outer surface of supporter is cylindrical, convenient for annular is arranged in the side wall of supporter
Groove, the pouch of setting annular and flexible ring body, expansion ring body are located at the outside of pouch in groove, are that pouch is located at groove
The internal deeper position of relative telescopic ring body so that including pouch, flexible ring body connect inlet tube outside, in pouch for being passed through
Hydraulic oil, exhaust pipe is for the gas inside pouch to be discharged in input hydraulic pressure oil.When the utility model is used, bulging will be needed

Use cost.In addition, pouch is due to being located at the relatively deeper position of inside grooves in the utility model, when supporter level is put
When setting, pouch is limited by recess sidewall in the up-down direction so that pouch is mutual with supporter in expansion process
Active force can be offset by recess sidewall, the active force hundreds and thousands of tons easily for the bulging operation of large ring,
And the utility model using support body sidewall groove structure, directly overcome the problems, such as this, without additionally going to limit using other structures
Expansion of the pouch processed towards upper and lower directions, it is ensured that the acting in flexible ring body of high degree is capable of in the acting of hydraulic coupling, is reduced
The loss of idle work improves the working efficiency of the utility model.
Preferably, the inlet tube, exhaust pipe are pierced by from recess sidewall to supporter.Inlet tube, exhaust pipe from
Recess sidewall is pierced by, it is ensured that bulging operation will not be interfered and be influenced, improve the stability in use of the utility model.
Preferably, the supporter is annular in shape.Reduce conducting oneself with dignity, carrying easy to remove, reducing cost for supporter.
Preferably, the expansion ring is arranged elastic ring in vitro；The flexible ring body is by several staggered outer sector circulars
Block, interior wing ring block composition；The outer surface of several outer sector circular blocks constitutes the outer surface for ring body of stretching, and the interior wing ring block is located at phase
In notch between adjacent two outer sector circular blocks.It is the outer sector circular block being intervally arranged, the flexible ring body of interior wing ring block composition, China and foreign countries
The outer surface for fanning ring block constitutes the outer surface for ring body of stretching, and is that the outer surface of two neighboring outer sector circular block is in contact with each other, jointly
The outer surface for constituting ring body of stretching, since outer surface is connected between two adjacent outer sector circular blocks, according to the shape of fan ring,
It is intermediate that necessarily there is notch, therefore interior wing ring block is arranged in the notch between two outer sector circular blocks.Outer sector circular block, interior wing ring block
Inside have pouch blocking, being arranged elastic ring in outside is blocked.This programme during the work time, when being filled in pouch
When hydraulic oil, pouch pushes ring body of stretching to expand outward, pushes each outer sector circular block to be moved outward, while pushing interior wing ring
Block carries out displacement in the notch between two neighboring outer sector circular block so that the expansion ring body in this programme can be stretched outward
Contracting expansion, greatly improves the service life and working efficiency of flexible ring body.After the completion of bulging operation, lay down in pouch
When hydraulic oil, under the reset force effect of elastic ring, and automatically outer sector circular block, interior wing ring block can be resetted, into one
Step reduces manpower consumption, improves working efficiency.
Preferably, side of the two sides of the interior wing ring block respectively with the outer sector circular block of both sides fits.It is interior wing
The left and right sides of ring block is bonded with the side of the outer sector circular block of both sides respectively so that when interior wing ring block carries out displacement in notch,
It can be slided along the side of both sides outer sector circular block, it is ensured that stabilization of the interior wing ring block in moving process avoids interior wing ring
Block loosens.
Preferably, the elastic ring is rubber ring.Using rubber it is excellent elasticity from outside block outer sector circular block and meanwhile really
It protects and excellent reset capability is provided.
Preferably, the outer sector circular block, interior wing ring block are made by steel.Ensure that the utility model has enough
Rigidity and intensity.
Preferably, the supporter is made by steel.Ensure that the utility model has enough rigidity and intensity.
Preferably, the pouch is made by rubber material.Ensure that pouch has well after being filled with hydraulic oil in pouch
Elastic force, it is ensured that pouch can apply sufficient motive force to flexible ring body.
The utility model compared with prior art, has the following advantages and advantages：
1, a kind of large ring bulging of the utility model mechanism, simple in structure, easy to operate and ultrahigh in efficiency can be realized
Simply, the purpose that bulging processing is efficiently carried out to large ring, greatly reduces compared to traditional large-scale bulging equipment
Production and use cost.
2, a kind of large ring bulging of the utility model mechanism, using the groove structure of support body sidewall, without additionally making
Go limitation pouch towards the expansion of upper and lower directions with other devices, it is ensured that the acting of hydraulic coupling is capable of acting on for high degree and is stretched
In contracting ring body, the loss of idle work is reduced.
