Detailed description of the invention
Refering to Fig. 1 to 3, a kind of ten roller straighteners, including entablature assembly 1, sill assembly 2, columns assemblies 3, aligning
Roller 4, it is overall that entablature assembly 1 is fixedly connected into straightening machine frame by columns assemblies 3 and sill assembly 2, specifically, column
Assembly 3 be four and in the both sides being fixed on sill assembly 2 side by side on, often set columns assemblies 3 is by a root post and solid
Determining nut composition, entablature assembly 1 and sill assembly 2 are linked together and bear straightening force, columns assemblies 3 outer surface enters
Row chromium plating polishing, in smoothing roll 4 coordinates the frame entirety being arranged on entablature assembly 1 and sill assembly 2 composition successively,
Smoothing roll 4 is the most corresponding five groups arranged, smoothing roll 4 includes roll body 41, roll shaft 42, bearing 43, roller seat 44, protective jacket 45,
Roll shaft 42 is through roll body 41 is internal and interference fit is integral, and the two ends shaft shoulder engagement sleeves of roll shaft 42 is connected in bearing 43, bearing
In 43 internal cavities being fixed in roller seat 44, protective jacket 45 is wrapped in the outer surface of roller seat 44 and forms one, and protective jacket 45 can
What the iron scale preventing steel tube surface entered roll shaft 42 and bearing 43 coordinates face, and further, the outer surface of roll body 41 is hyperbolic
Bank face, bearing 43 is double-row self-aligning roller bearing, takes into full account that roll body 41 impacts and the operating mode of rotating speed, and bearing 43 lubrication is passed through
The most periodically oiling, the bottom of entablature assembly 1 is connected with butterfly spring bascule 13, and the top of sill assembly 2 is connected with
Lower butterfly spring bascule 24, upper five smoothing rolls 4 arranged are fixed together with upper butterfly spring bascule 13, lower five layouts
Smoothing roll 4 is fixed together with lower butterfly spring bascule 24, and affixed after up and down corresponding smoothing roll 4 axis same vertically
In face, entablature assembly 1 includes that the first power transmission shaft 11, screw-down 12, the first power transmission shaft 11 coordinate and is arranged on described pressing machine
Position, center in structure 12, screw-down 12 is connected with upper butterfly spring bascule 13 and is integrated, and five set screw-downs 12 are used
In upper five smoothing rolls 4 arranged being made pressure regulation, thus realize the opening degree regulation of five smoothing rolls 4 arranged, its
Regulative mode be by motor through decelerator (not shown) turn-screw, screw drive upper five arrange smoothing rolls 4 depress or
Pressing regulation, the upper butterfly spring bascule 13 that screw-down 12 is connected simultaneously is in order to eliminate pressure leading screw gap, in raising
Five smoothing roll 4 displacement accuracies arranged, its displacement accuracy is in the range of 0.1mm, and the corner of upper five smoothing rolls 4 arranged is adjusted
Joint is motorized adjustment, and has hydraulic locking function, and corner adjusts to be had mechanical scale and indicate, and sill assembly 2 includes the
Two power transmission shafts 21, reductor 22, pressing mechanism 23, second driving shaft 21 cooperates together with the trunnion axis of reductor 22,
The vertical axis cooperation of reductor 22 is arranged on the center, inside pressing mechanism 23, presses mechanism 23 and joins with lower butterfly spring bascule 24
Conjunction connects as one, and specifically, three, the centre of lower five smoothing rolls 4 arranged presses regulation by pressing mechanism 23, enters
The recurvation amount of three, the centre that line height regulation can realize lower five smoothing rolls 4 arranged adjusts, and lower five layouts is strong
Two, the edge of straight roller 4 does not regulates, and one of them has opens function soon, can control the rate travel of steel pipe, press mechanism
23 press regulates by motor through reductor 22 turn-screw, three, the centre work of lower five smoothing rolls 4 arranged of screw drive
Pressing regulation, the corner regulation of lower five smoothing rolls 4 arranged is identical with upper five smoothing rolls 4 arranged.
Ten all main drive rollers of smoothing roll 4 of ten roller straighteners, and respectively by a direct current generator by decelerator,
Gear distribution box and cardan shaft driving, mair motor band encoder forms speed closed loop with electric control system, it is ensured that ten alignings
Roller 4 speed sync, three, the centre of upper five smoothing rolls 4 arranged and lower five smoothing rolls 4 arranged can carry out Vertical Square
To altitude mixture control, ten smoothing rolls 4 can individually carry out angular adjustment simultaneously, and the steel pipe for different tube diameters can pass through
The altitude mixture control of smoothing roll 4 and angular adjustment, it is ensured that the roll surface of roll body 41 is intact with steel tube surface to be contacted.The outer surface of roll body 41
Having identical roll forming, roll shape curve is the quasi-hyperbola roll forming through actual verification, roller footpath, barrel length, roll spacing and
The design of angle is meeting on the premise of load intensity requires, it is ensured that steel pipe has with roll body 41 and sufficiently long contacts line, makes steel
Pipe has enough plastic deformation length in every pair of roll body 41, has enough stability in whole straightening process simultaneously,
Thus effectively ensure the flattening precision of steel pipe especially light-wall pipe and good surface quality, cold-drawn cold rolling for aligning it
After steel pipe aligning linear precision be 0.3mm/m, aligning hot finished steel pipe aligning linearity conservative value be 0.5mm/m, this be because of
For ovality and the surface quality reason of hot finished steel pipe, next to that a yield limit and the cost of ten roller straighteners asked
The equilibrium problem controlled.
In sum, the present invention ten roller straightener the smoothing roll of sill assembly by 2 change into 5 rollers and with upper beam in
Opposed layout, embodies pressure function as far as possible, improves aligning ovality and reduces straightening blind area, upper five smoothing rolls arranged
Need to again make, it is ensured that the parameter of smoothing roll is unified, so that the change row that steel pipe deforms enough on smoothing roll is long up and down
Degree.
Embodiment described above is only to be described the preferred embodiment of the present invention, the not structure to the present invention
Think and scope is defined.On the premise of without departing from design concept of the present invention, this area ordinary person technology to the present invention
Various modification that scheme is made and improvement, all should drop into protection scope of the present invention, the technology contents that the present invention is claimed,
All record in detail in the claims.
