The utility model discloses a nodular cast -iron pipe hydraulic pressure coalignment, simple structure, in the gyro wheel for forked tail form, moves the roller train and decide the steel pipe that interval between the roller train can compatible all kinds of diameter through the regulation, and the laminating is closely, move the roller train and the realization of hydraulic pressure elevating gear is passed through in the variable -spacing adjustment decided between the roller train, labour saving and time saving, drive arrangement have speed adjustor, can adjust the slew velocity of steel pipe, the quality of improvement product.
Description
Technical field
This utility model is related to a kind of hydraulic straightening device, and in particular to a kind of ductile iron pipe hydraulic straightening device
Background technology
In ductile iron pipe manufacturing enterprise, such trouble is often met with, i.e.,：DN80-400 × 6000mm centrifugal castings
The small dimension cast tube of iron pipe production, it from centrifugal tube casting machine extract when majority can be in bending, this kind of cast tube Jing graphitizing annealings
After process, although its bending take a favorable turn, but such as DN80, DN100, DN125 and DN150 small dimension cast tube still has a certain amount of
Buckling phenomenon can not be completely eliminated.Swan-neck is flowed into after ductile iron pipe finishing line, is directly being applied if not dealing with
Lining operation is when carrying out cement lining operation, and its task difficulty is larger, and it is irregular that socket two ends are clearly present thickness of inner lining, coated lining quality
Bad, there is the presentation quality of more defective effect cast tube on surface, needs to be done over again in process of production often or adopts manually to enter
Row is repaired, and is brought compared with burden to production.It is at home to adopt people in most manufacturers if processing this kind of pipe
Work method carries out alignment with jack, and when carrying out alignment process in this way, swan-neck must hang out from production line, alignment
Process time length, inefficient, and can not be by swan-neck school completely is good and alignment request up to standard, this processing mode is also undesirable.
The content of the invention
In order to solve the above problems, the utility model proposes a kind of ductile iron pipe hydraulic straightening device.
The technical solution of the utility model is：A kind of ductile iron pipe hydraulic straightening device, including in frame, bottom of the frame
Feel at ease dress hydraulic lift, be connected on hydraulic lift be used for hydraulic lift provide power hydraulic pump and
In hydraulic cylinder, the fixed plate of hydraulic lift upper end installation, the dynamic roller group by fixing axle in fixed plate, frame
Three groups of portion's installation are determined to be carried in roller group, the driving means for driving steel pipe rotation of frame front end installation, driving means
