Description
Technical field
The present invention relates to a kind of argon arc welding machine auxiliary equipment, specifically refer to steel-tube internal rag cutter.
Background technology
When steel-pipe welding, for ensureing good welding effect, generally by soldering tip with treat that Coiling Welded Pipe is placed in semi-enclosed casing, when conveniently passing into protective gas, while also avoiding welding, Mars splashes everywhere.But after steel pipe partial welding, weld seam is directly exposed in air, due to the difference of air themperature and weld seam self temperature, can make weld seam by high temperature directly to low-temperature transformation, steel pipe seam is because the cataclysm of temperature during this time, can reduce the intensity of self, the stability in use of steel pipe is reduced, when serious, can directly cause steel pipe seam sealing-off; And near weld seam, inside and outside steel pipe, all can produce a certain amount of burr in the time of welding, make the steel pipe flow velocity decline of tube fluid in use, and the projection of commissure is also easily corroded, and then cause commissure bulk strength to decline, the service life of having reduced steel pipe; Traditional inner-burr cleaning equipment is mainly focused on the solder residue at weld seam and weld seam periphery place and the removing of projection, and the solder residue and the projection that during for welding, are scattering into other parts of steel pipe inner wall are cleared up not thorough.
Summary of the invention
The object of the present invention is to provide steel-tube internal rag cutter, can carry out, without dead angle cleaning, improving the serviceability of steel pipe to the projection that the solder residue of steel pipe inner wall and when welding produce.
Object of the present invention is achieved through the following technical solutions:
Steel-tube internal rag cutter, comprise central shaft, on described central shaft, be provided with three cambered blades, three described cambered blades and central shaft are hinged and lay respectively on 1/3rd outer walls of central shaft, fixed head is installed at central shaft upper and lower two ends and cambered blade is arranged between two fixed heads, on described fixed head, be also provided with block, one side of block is that arc-shaped concave and arc-shaped concave contact with the arc out conductor of cambered blade, also comprises the blade angle governor motion being arranged between cambered blade.When the present invention works, drive central shaft to rotate by outside driving arrangement, the cambered blade being positioned on central shaft rotates, and starts the solder residue on steel pipe inner wall and projection to remove, three cambered blades are positioned on 1/3rd outer walls of central shaft and are hinged with central shaft, make cambered blade to change it by blade angle governor motion according to the size of steel pipe caliber and remove radius, the removing scope that increases at any time or dwindle cambered blade, has increased practicality of the present invention, blade angle governor motion of the present invention adopts connected mode and simple structure flexibly, in ensureing that cambered blade is good fixing, angle between quick adjustment cambered blade and central shaft, shorten improper process time of the present invention, the solder residue of steel pipe inner wall and the cleaning efficiency of projection are improved, ensure the serviceability of steel pipe, in the time that the solder residue of central shaft arc of rotation shape blade and steel pipe inner wall and projection contact, the active force that cambered blade is suffered and reaction force produce larger impact to itself, be arranged on the block on fixed head, can the angle of cambered blade and central shaft arrive when maximum be also simultaneously arc sheet be subject to impacting maximum in, for cambered blade provides support, avoid cambered blade impaired.
Described blade angle governor motion comprises connecting rod and brace, connecting rod, brace are connected with inside arc with the arc outside of adjacent two cambered blades respectively, on brace, have deep-slotted chip breaker, on connecting rod, have internal thread hole, on deep-slotted chip breaker inwall, screw thread is installed, also comprise screw rod, described screw rod is through internal thread hole and deep-slotted chip breaker threaded engagement.In the time that the steel pipe of different tube diameters size is carried out to inner wall cleaning, rotating screw bolt, the threaded engagement in screw rod and deep-slotted chip breaker, and then make the angle of cambered blade and central shaft become large, brace and connecting rod all adopt metal alloy material, and ensureing provides stable support to cambered blade.
On described deep-slotted chip breaker, rule is installed.In the time adjusting the corner dimension of cambered blade and central shaft, need to synchronously adjust three cambered blades, to avoid cambered blade with steel pipe inner wall loose contact or not contact, the rule arranging can provide standard for the adjustment of cambered blade, the cleaning scope of three cambered blade institutes radiation is consistent with pipe diameter, ensures good cleaning effect.
Also comprise shutter, described shutter is arranged between two adjacent cambered blades and the two ends of shutter are connected with two fixed heads respectively.In the time that cambered blade is cleared up steel pipe inner wall, removed solder residue and the projection of getting off by cambered blade and can between blade and blade, mutually collide, affect cleaning effect; The shutter arranging can by can be by the solder residue of having disposed and protruding centralized collection the fixed head place to central shaft bottom, reduce the impact of solder residue on cleaning process.
Be arranged on the fixed head of described central shaft bottom and have discharge opening.Solder residue in the accumulation of fixed head bottom is directly discharged by discharge opening, has improved cleaning effect.
The present invention compared with prior art, has following advantage and beneficial effect:
1, steel-tube internal rag cutter of the present invention, blade angle governor motion adopts connected mode and simple structure flexibly, in ensureing that cambered blade is good fixing, angle between quick adjustment cambered blade and central shaft, shorten improper process time of the present invention, the solder residue of steel pipe inner wall and the cleaning efficiency of projection are improved, ensure the serviceability of steel pipe, in the time that the solder residue of central shaft arc of rotation shape blade and steel pipe inner wall and projection contact, the active force that cambered blade is suffered and reaction force produce larger impact to itself, be arranged on the block on fixed head, can the angle of cambered blade and central shaft arrive when maximum be also simultaneously arc sheet be subject to impacting maximum in, for cambered blade provides support, avoid cambered blade impaired,
2, steel-tube internal rag cutter of the present invention, in the time that the steel pipe of different tube diameters size is carried out to inner wall cleaning, rotating screw bolt, threaded engagement in screw rod and deep-slotted chip breaker, and then the angle that makes cambered blade and central shaft becomes large, brace and connecting rod all adopt metal alloy material, and ensureing provides stable support to cambered blade.
