Description
Technical field
The present invention relates to pipe fitting cleaning equipment, in particular to steel pipes with straight inner burr cutters.
Background technique
When steel-pipe welding, to guarantee good welding effect, semi-enclosed cabinet generally is placed in by soldering tip and to Coiling Welded Pipe
It is interior, while being conveniently passed through protective gas, Mars splashes when also avoiding welding.But after steel pipe partial welding,
Weld seam is directly exposed to air, due to the difference of air themperature and weld seam own temperature, can make weld seam from high temperature directly to
Low-temperature transformation, during which steel pipe seam can reduce the intensity of itself, so that the stability in use of steel pipe drops because of the cataclysm of temperature
It is low, steel pipe seam desoldering can be directly contributed when serious；And it can be generated inside and outside steel pipe near weld seam in welding a certain amount of
Burr, so that the flow velocity decline of steel pipe tube fluid when in use, and the protrusion of commissure is also easy to be corroded, and then causes to weld
Integral strength declines at seam, reduces the service life of steel pipe；Traditional inner-burr cleaning equipment mainly focuses on weld seam and weld seam
The removing of solder residue at periphery and protrusion, and for be scattering into when welding the solder residue of steel pipe inner wall other parts with
And then cleaning is not thorough protrusion.
Summary of the invention
The purpose of the present invention is to provide steel pipes with straight inner burr cutters, can carry out to the burr on steel pipe inner wall thorough
Bottom cleaning, to improve the service life of steel pipe.
The purpose of the invention is achieved by the following technical solution:
Steel pipes with straight inner burr cutter, including cylinder, central axis, fixed plate and pedestal, fixed plate will be connected thereto
The cylinder upper end it is closed, the pedestal is fixedly connected with the lower end of cylinder, and surface middle part is fixed on the base
Screw rod, central axis activity extends downwardly behind fixed plate middle part, and is provided with screw thread in the middle along the axis direction of central axis
Through-hole, the screw rod matched with tapped through hole extend to cylinder upper end after running through tapped through hole, are provided on the central axis
The cutting sheet of multiple arcs, multiple cutting sheets and central axis are hinged and are evenly distributed on the outer circle wall of central axis, and
It is provided with multiple scallop holes being connected to tapped through hole on its external wall along the radial direction of central axis, and scallop hole is located at adjacent two
Between cutting sheet, multiple connecting rods corresponding with scallop hole are equipped on screw rod outer wall, connecting rod extends outwardly after running through scallop hole,
And it is fixed with block on the extended segment of connecting rod, the axial direction along the cylinder is provided with multiple adjustment holes on its outer circle wall, cuts
Pitch cutting extends outwardly after running through adjustment hole, limited block is additionally provided on the cylinder inner peripheral wall, in use, the one of limited block
Side is arc-shaped concave and arc-shaped concave is contacted with the arc out conductor of cutting sheet.
When the invention works, screw rod runs through tapped through hole, is made according to the specific size of pipe diameter by rotating screw rod
Relative motion occur between screw rod and central axis, and block is driven while connecting rod moves in scallop hole to move, it is real
Spacing between existing block and cutting sheet increases or reduces, and the position of multiple cutting sheets is forced to change, i.e., cutting sheet is logical
The outwardly extending part of toning knothole increases or reduces, so that the annulus constituted when the blade tip movement of multiple cutting sheets
The internal diameter of domain sizes and steel pipe matches, and then drives center axis rotation, cutting on central axis by external driving equipment
Pitch cutting rotation, starts to be purged the dirt on steel pipe inner wall, and the dirt in barrel body rotation after a few, on steel pipe inner wall
Projecting height reduce, screw rod is rotated once again at this time, so that the outwardly extending part of cutting sheet increases, to expand the clear of cutting sheet
Radius is managed, realizes the secondary cleaning to steel pipe inner wall, is then cleared up dirt thoroughly, and steel pipe inner wall will not be caused to damage,
To improve the transfer efficiency of steel pipe.Further, multiple cutting sheets are evenly distributed on the outer circle wall of central axis, so that cutting
Piece can change it by blade angle regulating mechanism according to the size of steel pipe caliber and remove radius, increase at any time or reduce and cut
The removing range of pitch cutting, increases use scope of the invention；And when the angular adjustment of cutting sheet utmostly when, i.e. cutting sheet
Arc out conductor and adjustment hole side wall when contacting, the arc-shaped concave of limited block is also contacted with cutting sheet arc lateral wall, to reinforce
The stability of strutting system of cutting sheet in use, avoid active force suffered by cutting sheet and reaction force to itself generate compared with
Big impact reduces cutting sheet and the probability that stress fractures occurs.
The block is fan-shaped, and the inner arc surface of block is contacted with the outer circle wall of central axis.Preferably, fan-shaped
Block inner sidewall is contacted with the outer circle wall of central axis, and its end face is then contacted with the inner arc surface of cutting sheet, when screw rod stops
After rotation, the end face of block is directly contacted with cutting sheet is transformed to face contact by point contact, i.e., after cutting sheet stress, block
Stable support can be provided, for it to improve the cleaning efficiency of burr.
The outer diameter value of the connecting rod is one third of the scallop hole along the axial dimension of central axis.It is multiple to be in a horizontal state
Scallop hole is along the radially uniform distribution of central axis, and in the axis direction of central axis, the outer diameter value of the connecting rod is scallop hole edge
The one third of the axial dimension of central axis, it is ensured that connecting rod has enough activity spaces, to realize between block and cutting sheet
The adjusting of spacing size.
It is provided with the discharge hole being connected to inner barrel on the base.In fixed plate bottom, the solder residue of accumulation is direct
It is discharged by discharge hole, improves cleaning effect.
Compared with prior art, the present invention having the following advantages and benefits:
1, steel pipes with straight inner burr cutter of the present invention drives center axis rotation by external driving equipment, is located at center
Cutting sheet rotation on axis, starts to be purged the dirt on steel pipe inner wall, and in barrel body rotation after a few, steel pipe inner wall
On the projecting height of dirt reduce, rotate screw rod once again at this time, so that the outwardly extending part of cutting sheet increases, cut with expanding
The cleaning radius of pitch cutting realizes the secondary cleaning to steel pipe inner wall, then clears up dirt thoroughly, and will not make to steel pipe inner wall
At damage, to improve the transfer efficiency of steel pipe；
2, steel pipes with straight inner burr cutter of the present invention, when the angular adjustment of cutting sheet utmostly when, i.e. cutting sheet
When arc out conductor and adjustment hole side wall contact, the arc-shaped concave of limited block is also contacted with cutting sheet arc lateral wall, to reinforce cutting
The stability of strutting system of pitch cutting in use avoids active force suffered by cutting sheet and reaction force from generating itself larger
Impact, reduce cutting sheet and the probability that fractures of stress occur.
