A circular positioning disk (27) is arranged flexibly in the cavity of the shell (1); a bearing No.6 (22) and a bearing No.5 (21) are arranged between the positioning disk (27) and the feed disk (23); a bearing No.7 (24) and a bearing No.8 (25) are arranged between the shell (1) and the feed disk (23); the circumference of the feed disk (23) is provided with teeth, and the top plane of the feed disk (23) is provided with two symmetrical curved grooves (23-1), wherein a left knife block (9) and a right knife block (18) are arranged above the curved grooves (23-1); the knife blocks are provided with holes; a spring No.1 (10) and a knife No.1 (13) are arranged in the hole of the left knife block (9), while a spring No.2 (15) and a knife No.2 (14) are arranged in the hole of the right knife block (18); the pipe cutter cuts oil pipes through the rotation of the cutting knife, thereby avoiding deformation and shrinkage of the cutting faces of the oil pipes and creating convenient conditions for the aftertreatment of the of the cutting faces of the oil pipes.

Description

Rotary pipe cutter

Technical field

The utility model belongs to pipe cutting machinery, particularly a kind of rotary pipe cutter.

Background technology

At present, cut normally shear ram that preventer is with of the employed instrument of oil pipe in oil field brill, the workover treatment process, scissors moves along the oil pipe radial alignment, and cutting exists the fracture sectional dimension of shearing the back oil pipe and dwindles distortion like this, can't use to drag for anchor in the oil pipe and salvage once more.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned technical deficiency, provides a kind of fracture sectional dimension of cutting the back oil pipe not dwindle distortion, can make and drag for the rotary pipe cutter that anchor is beaten lawrencium once more in the oil pipe.

The technical scheme that the utility model technical solution problem adopts is: a kind of rotary pipe cutter of being made up of housing and loam cake, be characterized in being equipped with versatilely in the housing inner chamber positioning disk of annular, bearing six and bearing five are housed between positioning disk and feed plate, bearing seven and bearing eight are housed between housing and feed plate, circumference be on the feed shelter of tooth plane symmetry be provided with two curved grooves, symmetry is equipped with positioning disk versatilely in the radial hole of establishing on positioning disk, which is provided with left tool rest and right tool rest, tool rest is equipped with the hole, in the hole of a left side tool rest spring one and blade one are housed, spring two and blade two are housed in the hole of same right tool rest, blade one usefulness spacer pin one is fixing, blade dual-purpose spacer pin two is fixing, be equipped with little axle below left side tool rest and the right tool rest, little axle is contained in respectively in bearing three and the bearing four, bearing three and bearing four activity respectively are contained in the curved groove, feed shelter is meshed with gear, gear is located on the gear shaft, gear shaft is contained in bearing one and the bearing two versatilely, bearing one is fixed on the bearing support one, and bearing support is screwed on housing.

The beneficial effects of the utility model are: this pipe cutter avoids oil pipe cut end facial disfigurement to dwindle by the rotation cutting oil pipe of cutting blade, and the oil pipe place of incision is handled the condition that makes things convenient for of creating again.
