Description
Technical field
The invention belongs to machining equipment, relate in particular to a kind of overlarge-diameter high-precision ten-roller tube straightener.
Background technology
At present, in seamless steel tube production enterprise, cross-roll straightening machine is the most frequently used equipment of tube straightening.The cross roll straightening process is the most effectual way of tubing finishing.The general straightener that adopts, because roll spacing is less or roller is less (six rollers, seven rollers), transmission system is arranged the motor-decelerator-distributor box-cardan axis-smoothing roll modes that adopt more.Sometimes directly decelerator and distributor box are united two into one, make the associating distributor box.But this time,, be 1560mm so adjacent cardan axis length difference is also big because roll spacing is big.As the shortest cardan axis length is 2500mm, and (the roller range is big, and the too big cardan axis of knuckle is fragile) is then the longest reaches 8740mm, and needing increases additional support, has both increased cost, has also increased the roll change difficulty; Aspect tube straightener for pipe, the maximum φ 680mm of pipe diameter that the cross-roll straightening machine of present seamless steel tube production enterprise equipment can be aligned, and pipe diameter φ 400mm is above is six rollers, can't satisfy the aligning requirement of super-large diameter (φ 500～φ 920mm) high-accuracy weldless steel tube.
Summary of the invention
The present invention is the aligning demand that satisfies super-large diameter tubing, and the straightener of the ultra-large type ten-roller tube that can meet the need of market is provided, and the aligning pipe diameter can reach φ 920mm; The present invention adopts the vertical structure of roll straightening method, reaches the aligning purpose by the tubing alternating bending; Mainly constitute by: frame body, top roll adjusting device, reclining apparatus, straightening roller device, lower roll adjusting device, Left Drive device, right transmission device, cardan axis, distributor box, motor, decelerator, distributor box, protection oil cylinder, locking cylinder, rotating disk, slide, bearing pin, balancing cylinder, reducing motor, worm type of reduction gearing, support, pinion, gear wheel;
Its concrete technical scheme is: Left Drive device, right transmission device are divided into two group about frame both sides by two decelerators, four distributor boxes with symmetry by two direct current generators, form two distributor box forms of symmetrical oblique configuration, after driving distributor box by the motor gearing speed-reducer earlier, drive the straightening roller device that is arranged in the frame by ten corresponding cardan axis that dispose and carry out tube straightening, while two direct current generators keep the rotating speed unanimity by the speeds match servo-drive system of electric control gear; Ten smoothing rolls of straightening roller device divide five groups of formations, the skewed crossing of oblique balanced configuration symmetry roller is up and down, carry out lift adjustment by top roll adjusting device and lower roll adjusting device, the opening value of smoothing roll can be regulated between the 300-1000mm scope up and down, and the top roll adjusting device is identical with lower roll adjusting device structure and operation principle; Carry out the angle adjustment of straightening roller device by reclining apparatus, the smoothing roll angle adjustment can be regulated in 32-90 ° of scope; According to being rectified the steel pipe different-diameter, adjust suitable opening value and angle and realize φ 500～φ 920mm tube straightening; The present invention adopts each two distributor box form of being made up of two distributor boxes, can make whole transmission device reach, under the situation that does not increase the device space, can make the shortest elongated 1680mm of cardan axis, the longest cardan axis 1440mm that shortens, thereby reduce the length difference of adjacent cardan axis, layout is more reasonable.
Balancing cylinder and locking cylinder split and are arranged in parallel in upper rack, are ten respectively all, divide five groups, every group each two, are symmetricly set on respectively in the slide, and locking cylinder is connected with slide by bolt, and balancing cylinder is connected with slide by bearing pin; Balancing cylinder is used for eliminating the screw mandrel gap, guarantees roll gap adjustment required precision; Locking cylinder is by the locking rotating disk, and smoothing roll is not loosening when guaranteeing aligning.Balancing cylinder need not unclamp during the smoothing roll angle adjustment; Locking cylinder need not unclamp during the smoothing roll lift adjustment, Each performs its own functions for balancing cylinder, locking cylinder, the existing balance of solution, the public oil cylinder of locking need inconvenient defectives such as function switching, and balance, locking cylinder split and improved functional reliability, simplify the control of hydraulic pressure and electric-control system.
Four column sleeves guiding slide adopts Welding Structure, and the horizontal layout link connects balancing cylinder on the slide, and locking cylinder places in the slide (particular location is seen accompanying drawing 3), and (particular location is seen accompanying drawing 3, Fig. 4) arranges reclining apparatus in the slide side; Made full use of the slide space; Two guiding of slide are leant on cover and are arranged in lower, two guiding are leant on cover and are arranged in eminence in addition, four guiding of slide are leant on the four root posts location of cover by the frame body, improve the force-bearing situation of slide in the tube straightening process, reduce frame vibration, make the aligning process more stable, improve flattening precision (accompanying drawing 3 is seen in model position, position).
Reducing motor+worm and gear+gear-driven form, afterbody adopt a pair of gear drive; As shown in Figure 4: reducing motor and worm type of reduction gearing and pinion are fixed on the slide side by support; Gear wheel is fixed on the rotating disk; Angle adjustment realizes by the following method: reducing motor rotates by the worm type of reduction gearing driving pinion, and pinion drives dial rotation by driving gear wheel, realizes being fixed on rotating disk upper straightening roll angle adjustment.
The protection oil cylinder adopts the overhead buffer protection; Because straightener does not have the hydraulic protecting system; so possess fast discharging protection functions of the equipments; position by the locating hole on protection oil cylinder location cylindrical and the frame body; and be fixed on frame body top; put on the realization protection oil cylinder; it is oversize to solve existing frame body interior limited space and hydraulic protecting oil cylinder itself, changes problems such as operating very inconvenience.
Beneficial effect of the present invention: two distributor box forms that transmission device adopts two distributor boxes to form; The separate configuration form that top roll balancing cylinder and locking cylinder adopt; Adopt welded type four column sleeves guiding slide form; Adopt high accuracy angle modulation transmission device form; Adopt overhead buffer protection cylinder apparatus form; The present invention satisfies the aligning demand of super-large diameter tubing, and the aligning pipe diameter can reach φ 920mm.
