Description
Affiliated technical field
The utility model relates to the special equipment that a kind of spirally welded pipe is produced, particularly the equipment that the diameter and the circularity of spirally welded pipe pipe end certain-length is expanded adjustment.
Background technology
In the installing engineering of larger hydrocarbon pipeline, the butt joint between the steel pipe in the pipeline is connected, require tube end diameter and circularity must reach certain technical requirements.But the steel pipe of directly making at present need carry out hole enlargement to its termination and handle, and just can make its port diameter and circularity reach instructions for use.
Summary of the invention
The purpose of this utility model provides a kind of steel tube head expanding machine that at normal temperatures steel tube head is carried out the hole enlargement processing, so that the diameter of steel tube head and circularity reach instructions for use.
The technical solution of the utility model is: this steel tube head expanding machine is by main frame, main frame auxiliary equipment, hydraulic pressure and lubricating system, and electrical system is formed, its main frame is provided with can be along the slide of horizontal plane slip, portal frame is installed on slide, portal frame is provided with vertically moving installing rack, and installing rack one side is equipped with oil cylinder, and its opposite side is equipped with the hole enlargement unit; The support disk of this hole enlargement unit is connected with installing rack; Support disk is provided with a plurality of module groups (also claiming wedge) that can move radially along support disk, cooperate on its module group removable die blade is installed, this die blade directly contacts with the steel pipe inwall when hole enlargement is operated, the polygonal pyramid body with a plurality of inclined-planes of hole enlargement unit is installed in the piston rod head that oil cylinder stretches out, and each inclined-plane is corresponding with each the module group on the support disk and constitute and to be slidingly matched on the polygonal pyramid body.By adopting said structure, when hole enlargement is operated, when under the driving of the cone that is installed in the oil cylinder piston club head at oil cylinder piston when mobile in a certain direction, cone then make the module group that is close on the cone inclined-plane along support disk expansion radially outward move, the circumference that the module group is constituted increases, at this moment, in-oil cylinder hydraulic coupling affacts on the steel pipe inwall through cone, module group successively, make the stressed outside expansion in steel tube head position, produce plastic deformation after making pipe wall material take place to flow, the realization hole enlargement is handled.
The utility model has the advantages that,, can carry out the termination hole enlargement to the steel pipe of different inner diameters, but the hole enlargement scope is big by the module group of replacing differing heights and the die blade of different-thickness, high efficiency, the operating accuracy height, stable and reliable for performance.
Below in conjunction with accompanying drawing the utility model is further specified.

The specific embodiment
According to Fig. 1 and Fig. 2, the utility model main frame is provided with slide 5, portal frame 3 is installed on slide 5, portal frame 3 is provided with can be along the vertically mobile installing rack 6 of the track on this, installing rack 6 left sides are connected with hole enlargement unit 1, and the right side is connected with oil cylinder 2, are connected with the lifting device 4 that is used to promote installing rack 6 on the top of installing rack 6, oil cylinder 2 inner carriers are provided with a Control Shaft 7, and Control Shaft 7 is connected with sensing mechanism 9 by control mounted thereto cover 8.When hole enlargement was worked, the path increment of its oil cylinder can transmit by axle 7 and control cover 8, by 9 perception of sensing mechanism, forms the control signal in order to control oil cylinder stroke amount, guarantees by the precision of hole enlargement pipe end.
According to Fig. 3-Fig. 6, polygonal pyramid body 1-1 is installed on oil cylinder piston bar 2-1 head in the hole enlargement unit, support disk 1-6 is connected with installing rack 6 on the portal frame, at a plurality of T-slots of being radially distributed with of support disk 1-6, be equipped with in the groove and can only radially slide along support disk and can not be along the axially movable T shape of support disk piece 1-5, the piston rod of T shape piece 1-5 and the little cylinder diameter hydraulic cylinder 1-4 that is installed in the T-slot outer end is by being threaded, T shape piece 1-5 is connected with module group 1-2 by screw rod 1-7 simultaneously, on module group 1-2 top die blade 1-3 is installed, between the T-slot on the support disk 1-6, also be provided with radial groove, the wear-resisting 1-8 of inserting is installed in the groove, makes it between supporting disk 1-6 and module group 1-2 that is die holder, constitute sliding friction and pay.The characteristics of this hole enlargement cellular construction are, after the steel tube head hole enlargement finishes, the cone 1-1 of the piston rod 2-1 head of oil cylinder 2 makes drawback movement under oil cylinder piston drives, at this moment, being subjected to the path hydraulic cylinder 1-4 that the nitrogen accumulator exerts pressure then transmits by T shape piece 1-5 pressure to module group 1-2, the circumference that module group 1-2 is constituted dwindles, and can make the hole enlargement mould easily from being withdrawed from the expanding steel tube.This pressure transferring structure has played module group 1-2 equally when steel tube head expands hole enlargement and cone 1-1 keeps the effect that is adjacent to.
According to Fig. 7, Figure 10 and Figure 11, the Control Shaft of installing on the oil cylinder 27 is connected with the tooth bar 9-1 of sensing mechanism 9 by control cover 8, tooth bar 9-1 and the travelling gear 9-2 engagement that is installed on the installing plate 9-4, travelling gear 9-2 is in transmission connection by the turning cylinder formation of idler gear and Lineside encoding unit 9-3, when the piston of oil cylinder 2 moves, its path increment is converted to the rotational motion of encoder 9-3 turning cylinder through tooth bar 9-1 and gear 9-2, and be converted to electric impulse signal, be used to control the stroke accuracy of oil cylinder 2, guaranteed by the precision of hole enlargement pipe end.
According to Figure 12, when the utility model uses, be arranged in parallel by two expanding machines, the discharging of staggering is not disturbed when its centre-to-centre spacing can guarantee the independent separately hole enlargement in the left and right two ends of steel pipe mutually.Hole enlargement unit and portal frame, the constituting body of oil cylinder can be along the slide move left and right, and hole enlargement unit and oil cylinder can move up and down along portal frame simultaneously.Each expanding machine is joined a cover material-supporting device, to finish the coarse positioning between steel pipe and the hole enlargement unit.The hole enlargement unit move axially and move up and down the accurate location of finishing to steel tube head.
Adopt the utility model structure, also can be made into and be applicable to other expanding technology, as the steel pipe integral hole enlargement, the expanding machine of steel ring hole enlargement, steel cylinder hole enlargement etc.
