Description
Technical field
The present invention relates to a kind of steel pipe spinning machine and utilize the steel pipe processing technology of this spinning machine, especially overlength size seamless steel tube reducing subtracts wall processing spinning machinery.
Background technology
At present, seamless steel pipe spinning machine processing mode is mainly steel pipe axial-rotation, and the spinning roller being distributed in steel pipe surrounding is driven by external force and realizes spinning along steel pipe axial feed.During steel pipe rotary pressing processing, there is dimensional discrepancy and bend due to original steel pipe, steel pipe rotary is beated comparatively large, and problems such as splitting roller, electric current transfinites, easily appears in spinning wheel unbalance stress, is difficult to realize six meters of upper full-scale steel pipe Continuous maching.
Summary of the invention
The present invention is directed to above-mentioned defect, object is to provide a kind of swinging steel pipe spinning machine, and this spinning machine can realize the rotary pressing processing of overlength seamless steel pipe.
The technical solution used in the present invention is for this reason: comprise revolving body (1), is provided with the spinning cavity passed for steel pipe (5), plug (4) in revolving body (1); Described revolving body (1) side is provided with some spinning wheels (2); Described spinning wheel (2) can revolving body (1) autorotation relatively; Described steel pipe (5), plug (4) are driven across spinning cavity rectilinear motion by driving mechanism (1).
Described revolving body (1) side is provided with four spinning wheels (2), is distributed in symmetrically on revolving body (1).
Described each spinning wheel (2) establishes governor motion (3), automatically regulates the contact of each spinning wheel (2) and steel pipe (5).
Frame is provided with some centering bodies (7), it is arranged on lathe base (8).
Steel pipe processing technology, carry out according to following steps:
1) first by being lining among steel pipe (5) in plug (4), by steel pipe (5) through spinning cavity, and the centering of steel pipe (5) and revolving body (1) is realized by centering body (7);
2) steel pipe (5) is driven to do rectilinear motion by driving mechanism (1), revolving body (1) is driven to rotate relative to steel pipe (5) by mair motor (6), spinning wheel (2) rotates also with revolving body (1) and steel pipe (5) produces contact friction, makes spinning wheel (2) rotation realize processing steel pipe;
3) governor motion (3) be arranged on each spinning wheel (2) is controlled by controller, and the carrying out according to the contact signal adaptive between spinning wheel (2) and steel pipe (5) regulates, and keeps the stationarity between spinning wheel (2) and steel pipe (5).
Advantage of the present invention is: 1) revolving body of the present invention only does self rotation, and axial location maintains static, and steel pipe, axially across also moving axially, changes original processing mode; Mode steel pipe originally does axial-rotation, spinning wheel axially moves and rotation in spinning process, and this kind of mode all rotates, therefore due to the error manufactured and install due to steel pipe and spinning wheel, therefore easily beat in process, have impact on crudy; And steel pipe of the present invention does not do and rotates, only axially move, therefore its probability of beating is less, and due to the adjustment of governor motion, can adjust the contact between spinning wheel and steel pipe at any time, therefore it can ensure crudy; 2) the present invention is in spinning process, is realized the rotation of spinning wheel by the friction between spinning wheel and steel pipe, and owing to there is rotation, its friction mode becomes a friction, and its wearing and tearing are less, and spinning wheel can have longer service life; 3) the present invention carries out the fixing of steel pipe by plug, spinning cavity and thimble, and plug carries out liner to steel pipe, and spinning cavity carries out fixing steel pipe from outside, driving mechanism and thimble are fixed from both sides steel pipe; Therefore the present invention's fixing by some points, the parts of spinning machine necessity are utilized to double as fixture, therefore compact conformation, steel pipe fix, and spinning cavity, plug well support from inside and outside two ends steel pipe, effectively avoid steel pipe beating in process; Ensure crudy; 4) and because steel pipe pass through from spinning cavity, and spinning wheel is fixed on revolving body, be equivalent to spinning wheel and steel pipe one like this, even if there is radial minor motion in steel pipe, spinning wheel also can be moved thereupon, thus reduce relative bounce amount between the two, thus improve steel pipe crudy.

Detailed description of the invention
The circular spinning revolving body 1 of the present invention at the uniform velocity rotates around self axle, and make revolution motion, revolving body 1 is circumferentially uniformly distributed four spinning wheels 2, the inner spinning cavity forming hollow.Plug 4 liner, in steel pipe 5, fixes non rotating relatively with steel pipe 5, together through the spinning cavity of revolving body 1.Spinning 2 is taken turns in steel pipe 5 exterior surface, and applies certain pressure effect to steel pipe 5, realizes subtracting wall processing to steel pipe 5 undergauge circumferentially along with revolving body 1 rotates.Spinning wheel 2, by frictional force driven rotary, realizes rotation, reduces wear.Meanwhile, plug 4 is driven by hydraulic cylinder 9, with steel pipe 5 together uniform rectilinear through revolving body 1, realizes the rotary pressing processing to steel pipe 5.
Each spinning wheel is equipped with lifting regulating mechanism 3, for regulating different drafts, steel pipe 5 is processed into different finished sizes.Multiple spinning wheel 2 can synchronous adjustment, realizes rapid adjustment, also can adjust respectively, finely tune after meeting the wearing and tearing of spinning wheel 2.
In process, lathe base 8 is furnished with multi rack centering body 7, realizes steel pipe 5 and revolving body 1 centering.
Because revolving body 1 only do self rotate, position maintains static, steel pipe 5 axially across, solve revolving body 1 driving problems, can realize ultralong steel tube processing.The electric part of spinning machine controls and hydraulic restraint feed system composition primarily of revolving body 1 mair motor 6 and rotating speed thereof.
Spinning wheel 2 symmetry of the present invention be distributed in steel pipe 5 outer surface, make the surperficial uniform force of steel pipe 5, each specification, material etc. according to concrete processing steel pipe of its number is determined.
As shown in Figure 1, steel pipe 5 internal lining mandrel 4 of the present invention, outside is spacing by spinning cavity, and two ends are supported by hydraulic cylinder 9, centering thimble respectively.
The present invention further can arrange multiple spinning cavity on the path of steel pipe 5, to support steel pipe 5.
Spinning wheel 2 of the present invention can establish pressure sensor, pressure between real-time detection itself and steel pipe 5, and regulate pressure between steel pipe 5 and spinning wheel 2 as information by governor motion 3, simultaneously by the speed of gyration of controller conservative control steel shaft to translational speed and revolving body 1.
