By adopting a pure connecting rod way, the structure of the device is simplified extremely, thus decreasing the outline size, lowering the equipment investment and the maintenance cost, and realizing the cleaning production; in the openness range of Phi 350 to Phi 1000mm , the centering precision is not over 0.5mm in the diameter direction.
Description
Technical field:
The utility model relates to a kind of centring means, the roller arrangement of especially feeling relieved.
Background technology:
At present, the centering roller arrangement is one of smelter seamless steel pipe visual plant of piercing one section on production line backstage, and main effect is to improve the rigidity of punching machine post rod and guarantee push rod and the high precision fixed core of hollow billet.Seamless steel pipe is in the process of piercing, push rod not only will rotate with hollow billet, but also to bear huge axial force, if at high temperature push rod does not have sufficiently high rigidity just will inevitably bend, like this to guarantee the hollow billet wall thickness all even perforation procedure be totally unfavorable smoothly.So, usually on perforation production line backstage one section arrange some groups of centering roller arrangements successively along the roll line direction, the centering roller arrangement is held push rod tightly in perforation procedure, mainly be that prevention is owing to the push rod insufficient rigidity occurs bending and deformation, guarantee the push rod center line on roll line, prevent hollow billet endoporus off-centre.In China seamless steel tube production enterprise, the version that perforation unit centering roller arrangement adopts is more, mainly contains pure linkage and geared linkage mechanism etc.But these structures mainly contain following characteristics and deficiency: the centering roller opening degree of (1) these structures all below Φ 400mm, only is suitable for using in middle-size and small-size punch; (2) adopt simple bar linkage structure, what adopt usually is the adjustable length lever, is difficult to guarantee that lever has sufficiently high rigidity, is difficult in the large-scale or super-huge punch and adopts; (3) geared linkage mechanism complex structure, device fabrication and maintenance cost are higher, and in addition, because the restriction of gear lubrication condition, operating environment is easily polluted, and operating cost is higher; (4) the roll structure form versatility of in the past feeling relieved is relatively poor, limited by the device space, and a kind of version is difficult in the perforation unit of other specifications and adopts.
The utility model content:
For remedying above-mentioned deficiency, pure connecting rod mode is adopted in this novel centering roller arrangement design, and its structure is mainly by formations such as frame 1, oil cylinder 2, oil cylinder 3, interlock plate 4, worm and gear lift 5, roller 6, lever 7, pull bar 8, lever 9, lever 10, pull bar 11, fixed axis 12, fixed axis 13, fixed axis 14, support 15, central shafts 16; Wherein: roller 6 has been the centering effect, reaches three rollers such as lower roll of being made up of two rollers by top roll, constitutes 3 clamping hollow billets of centering roll form.
Technical scheme:
Frame in the novel centering roller arrangement is a welding structure, by being bolted on the support 15; Employing is bolted to the moving interlock plate 4 that provides constraints of the driving below of the oil cylinder 3 above the frame left side and swings around its fixed axis 14, interlock plate 4 is by driving pull bar 8, pull bar 11 and oil cylinder 2 are given transmission of power on the lever 7 of its top, the lever 9 of one side, three levers such as lever 10 grades also rotate its central shaft 16 around three configurations separately synchronously, thereby realize that the roller of being made up of three rollers 6 carries out high precision fixed core, be positioned at the worm and gear lift 6 at position, frame 1 lower-left by bolting, it mainly is an opening degree scope of controlling this centering roller arrangement by the pendulum angle scope of the interlock plate 4 that provides constraints.The oil cylinder 2 major control top rolls that the frame upside is set in perforation procedure play the effect of pull bar, and 2 work of punch off oil cylinder drive upwards swing of top roll, and hollow billet is transferred to roll line by punch backstage poking device.
Lever 7 and interlock plate 4 can swing and be connected with each other by oil cylinder 2 around fixed axis 12 and fixed axis 14 separately respectively, lever 9 and lever 10 shared fixed axis 13, and they link to each other with interlock plate 4 with pull bar 8 by pull bar 11 respectively.
Determine the maximum opening degree of centering roller according to the specification of waiting to pierce hollow billet, centering roller maximum opening degree is to realize by screw mandrel Position Control interlock plate 4 pendulum angles of adjusting worm and gear lift 5.Oil cylinder 2 piston rods all stretch out during operate as normal, and hollow billet pierces process to be finished, and oil cylinder 2 piston rods withdrawal top roll is opened separately, and hollow billet is transferred to by roll line.The synchronous on-off of centering roller arrangement middle roller 6 is to be controlled by stretching of oil cylinder 3, and roller 6 closes when stretching out, and roller 6 is opened during withdrawal.Used a pair of oil cylinder is realized the three-roller linkage and the top roll single action of roller 6 as power resources.Interlock plate 4 one sides are provided with oil cylinder 2, and oil cylinder 2 belows one side is provided with worm and gear lift 5, and the top is provided with roller 6.Lever adopts foundry goods, and has increased cross dimensions, has improved the integral rigidity of centering roller arrangement, helps realizing high precision fixed core.
Beneficial effect:
Adopted novel link mechanism, realized that device structure farthest simplifies, overall size reduces, and equipment investment and maintenance cost reduce has also realized cleaning production; Lever wherein all adopts foundry goods, has guaranteed the integral rigidity of this device, improves centering precision and product size precision; In Φ 350～Φ 1000mm opening degree scope, centering precision is no more than 0.5mm in diametric(al), has not only realized high precision fixed core, and big opening degree scope makes it possess very strong versatility.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is novel centering roller arrangement structural representation.
