Description
Technical field
The present invention relates to a kind of steel pipe processing device, especially a kind of cleaner for inner wall of steel pipe that is used for elongated stainless steel disc inside pipe wall cleaning.
Background technology
Steel pipe is behind machining deformation, and can there be impurity such as some lubricant greases and metallic particles in its inner wall surface, if do not remove totally, can influence the steel pipe service life and the scope of application.Present small-sized seamless steel pipe internal wall cleans the general liquid medium that adopts earlier steel pipe is carried out soaking and washing; Clean with spray gun by the workman is manual again; In this process, be easy to cause cleaning fluid to leak; If be splashed to the operating personnel and can damage on one's body, and cleaning fluid leaks and can influence cleaning performance and efficient.Minority cleaner for inner wall of steel pipe complex structure, cost is high, is not suitable for using producing.In addition; Present cleaning device; Like Chinese patent 200820153201.5 disclosed a kind of seamless steel pipe internal wall cleaning spray guns, be to lean on the spray power of shower nozzle that the steel pipe inwall is cleaned, because shower nozzle spray power is limited; So this cleaning spray gun is not suitable for elongated stainless steel coil pipe, can't elongated stainless steel disc inside pipe wall be cleaned up.
Summary of the invention
The present invention will solve the shortcoming of above-mentioned prior art, provides a kind of rational in infrastructure simple, cleans cleaner for inner wall of steel pipe safely and effectively, and the inwall that is specially adapted to elongated stainless steel coil pipe cleans, and satisfies the production demand.
The present invention solves the technical scheme that its technical problem adopts: this cleaner for inner wall of steel pipe; Comprise water pump, four-way change-over valve; Four-way change-over valve be provided with water inlet pipe, drainpipe and about two tube connectors, the end of two tube connectors is connected with sleeve pipe respectively, has the cavity that is communicated with tube connector in the sleeve pipe; And the front end of sleeve pipe forms the socket joint hole that is complementary with steel tube end part, and cavity is connected with the socket joint hole.During use, stainless steel coil pipe two is inserted in respectively on two sleeve pipes, leads to cleaning fluid toward water inlet pipe through water pump; Through four-way change-over valve; Flow out in the stainless steel coil pipe from the tube connector in left side and to wash, tube connector flows back into four-way change-over valve from the right side again, discharges from drainpipe then.After the four-way change-over valve switching-over, then tube connector flows out cleaning fluid from the right side, and tube connector flows back to from the left side again.Rely on the power of water pump like this, add the effect of four-way change-over valve, cleaning fluid just can wash in steel pipe repeatedly back and forth, thereby elongated steel pipe inwall is cleaned up.
Further, said cleaner for inner wall of steel pipe also has at least one and places the emery cloth group in the steel pipe, and the inner, socket joint hole is provided with limiting section, and the radial height of said limiting section in sleeve pipe is greater than the wall thickness of steel pipe.Emery cloth group is along with the impact of current, the inwall of friction steel pipe, thus further strengthen the effect that inwall cleans.And emery cloth is rolled into a ball under the effect of four-way change-over valve, flushing back and forth repeatedly, can with the steel pipe inwall clean more thorough.In the time of flushing, limiting section can guarantee that emery cloth group stays the steel pipe inwall, can not get into the sleeve pipe cavity, and the situation that causes stopping up the sleeve pipe inlet opening takes place.Cleaning is taken down an end of steel pipe after accomplishing from sleeve pipe, the group of the emery cloth in steel pipe water is gone out get final product.
Said cleaner for inner wall of steel pipe also has the anchor clamps that are used for fixing steel tube end part, and said sleeve pipe is located on the anchor clamps, and these anchor clamps are provided with base, the pressing plate that cooperatively interacts.Through the cooperation of base and pressing plate, can the end clips of steel pipe be fastened, in flushing, steel tube end part can not rocked, its maintenance is contacted with the tight of sleeve pipe, cleaning fluid can not leaked.
Said anchor clamps are provided with the clamping cylinder that is connected with air pump, and said pressing plate is fixed on the end that clamps cylinder piston rod; Be provided with reversal valve between said clamping cylinder and the air pump.Like this, can automatically steel tube end part be clamped through controlling cylinder.
Said anchor clamps are provided with the cylinder that holds out against that is connected with air pump, and hold out against between cylinder and the air pump and be provided with reversal valve, and said sleeve pipe is fixed on this end that holds out against cylinder piston rod.Like this, can automatically sleeve pipe and steel tube end part be held out against, keep closely contact through controlling cylinder.
Said anchor clamps are frame structure, and are divided into front and back two parts by dividing plate, and said sleeve pipe is positioned at frame rear portion, and said base and pressing plate are positioned at frame front, and dividing plate and framework front side board are provided with the through hole over against sleeve pipe.Frame structure is convenient to installing and fixing of equipment, the various places of can applying in a flexible way.
Be connected to Pnenmatic automatic switch on the said water inlet pipe, when pressure is excessive, will close automatically, ensured the security of device.
Said limiting section surface is provided with sealing ring.Like this, what steel pipe just can be firm has been socketed in the sleeve pipe, and through clamping cylinder and holding out against cylinder each other to the positioning action of steel pipe, can not cause cleaning fluid to leak when steel pipe is cleaned, and improves the security of production and processing.
The effect that the present invention is useful is: of the present invention rational in infrastructure, simple, be particularly useful for elongated stainless steel coil pipe.The cleaning that effect through water pump, four-way change-over valve can circulate to the steel pipe inwall is repeatedly raised the efficiency, and through the clamping action of clamp mechanism to steel pipe, has improved the security of production and processing greatly.Whole device is simple and simple to operation, has not only reduced production cost, but also has improved security, is fit to apply.
