Description
Technical field
The present invention relates to a kind of scale removal cutter, particularly a kind of pipe material inner wall scale removal cutter.
Background technology
In oil and gas industry, the oil pipe use of going into the well is influenced by underground environment, and tube inner wall is attached with the alkali dirt to some extent, and these alkali dirts influence the effective drift diameter of oil pipe.Need during well workover that the oil pipe that trips out ground is carried out the alkali dirt and remove, recover the standard latus rectum of oil pipe, this is one of requisite operation in the oil pipe reparing process.
Existing pipe material inner wall scale removal cutter generally is a rigid blade, and the blade tactical diameter is fixed, and diameter is less than normal, when removing the alkali dirt, always leaves one deck alkali dirt ring and can not remove.Though can improve cleaning effect through repeatedly removing, can not reach the degree of thorough removing alkali dirt ring.
Summary of the invention
The present invention provides a kind of pipe material inner wall scale removal cutter that improves descale effect in order to solve the deficiencies in the prior art.
The technical solution adopted for the present invention to solve the technical problems is: a kind of pipe material inner wall scale removal cutter, comprise cutter hub, and the fixedly connected knife bar in described cutter hub rear end, described cutter hub front end is provided with the guide cuts sword, and the outside, middle part of described cutter hub is provided with the elasticity cutting edge.
Described cutter hub afterbody is provided with spiral and sets upright cutting edge.
Described cutter hub inside is provided with the cleaning water channel, described elasticity cutting edge bottom is provided with boss, described boss is provided with briquetting, described briquetting is fixed on the elasticity cutting edge on the cutter hub by screw, and described elasticity cutting edge bottom is provided with groove, is provided with spring in the described groove, described spring one end connects groove, the other end communicates with cleaning water channel, and described cutter hub outside also is provided with chip area, and described chip area is provided with hole for water spraying.
Described elasticity cutting edge bottom is provided with two grooves and two springs, and described elasticity cutting edge is symmetricly set on the both sides at cutter hub middle part.
Described knife bar can rotate, and can the front and back rectilinear motion.
Described knife bar rear end is fixedly connected on the knife bar by screw thread.
Compared with prior art, cutter hub of the present invention front end guidance cutting edge in process is advanced in rotation can be removed the most of obstinate alkali dirt of tube inner wall; The elasticity cutter head is close to tube inner wall under the two-way function of spring, the carbide alloy on the elasticity cutter head can be removed the however, residual base dirt ring of tube inner wall, and spiral is set upright cutting edge and set upright cutter hub and also can remove the alkali dirt.Alkali dirt bits under the cutting flow out from chip area under the flushing of water under high pressure, reach the effect of cleaning.Adopt structure of the present invention, can removing tube inner wall alkali dirt in full force and effect, there is not alkali dirt ring in the tube inner wall of removing behind the alkali dirt.The present invention also can be used for the inwall dirt removal of other tubing series products.
