Description
Technical field
The utility model is related to cutter field, more particularly to a kind of oil-gas pipeline perforating cutter.
Background technology
Oil, natural gas, chemical pipeline etc. when laying, typically using buried or overhead form.Repaiied to pipeline
Answer, relocate, connect collateral branch's line, change valve when, it is necessary to carry out perforate operation in the case of with pressure or not with pressure.Generally,
Pipeline tapping is unable to fire operation, can only carry out operation with special tapping equipment, the welded flange pipe nipple first on perforate pipeline,
Then valve and tapping equipment are installed, perforate is carried out after pressure inspection：Tube wall is drilled through with centre drill to play the role of positioning, using tubular
Perforating cutter carries out perforate.
Existing perforating cutter, has that preponderance, handling be hard, perforate effect is poor, is solution problem above
Devise a kind of oil-gas pipeline perforating cutter.
The content of the invention
The utility model provides a kind of oil-gas pipeline perforating cutter, including cutter hub, and described cutter hub is cylindrical shape, described
Cutter hub on Middle face be provided with plugging hole, the surrounding of described plugging hole is uniformly provided with four clamping holes, above described cutter hub
Uniform between edge and four clamping holes to be laid with eight lightening holes, described plugging hole, clamping hole and lightening hole are through hole；
It is welded with described cutter hub bottom surface outer rim and is provided with a circle cutter tooth；Described cutter tooth is stepped tooth wide at the top and narrow at the bottom.
Further, described cutter hub material is Q345C steel plates.
Further, described cutter tooth material is cobalt-containing high speed steel.
The beneficial effects of the utility model are：A kind of oil-gas pipeline perforating cutter described in the utility model, conveniently makes
Loaded and unloaded with clamping manipulator, it is lightweight, save material；And perforate effect is good.
Brief description of the drawings
Fig. 1 is top view of the present utility model；
Fig. 2 is front view of the present utility model；
Wherein：1- clamps hole；2- lightening holes；3- plugging holes；4- cutter hubs；5- cutters tooth.
Specific embodiment
It is described in detail referring to the drawings below with reference to embodiment of the present utility model.
A kind of oil-gas pipeline perforating cutter, including cutter hub 4, described cutter hub 4 is cylindrical shape, above described cutter hub 4
Middle part is provided with plugging hole 3, and the surrounding of described plugging hole 3 is uniformly provided with four clamping holes 1, the described upper edge of cutter hub 4 and
Uniform between four clamping holes 1 to be laid with eight lightening holes 2, described plugging hole 3, clamping hole 1 and lightening hole 2 are through hole；
It is welded with the described bottom surface outer rim of cutter hub 4 and is provided with a circle cutter tooth 5；Described cutter tooth 5 is stepped tooth wide at the top and narrow at the bottom.
Further, the described material of cutter hub 4 is Q345C steel plates.
Further, the described material of cutter tooth 5 is cobalt-containing high speed steel.
Principle：
Described plugging hole 3 is used to connect tapping machine during oil-gas pipeline perforating cutter operation；The described convenience of clamping hole 1
Described oil-gas pipeline perforating cutter is loaded and unloaded using clamping manipulator；Described lightening hole 2 is in the oil-gas pipeline described in guarantee
While with the opening capability of perforating cutter, the weight of described cutter hub 4 is alleviated, save material.
Cutter tooth 5 is neither too hard, nor too soft using cobalt-containing high speed steel material, and toughness is good.
The above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as protection domain of the present utility model.
