Abstract
The invention discloses a turnable puncher top centering roll device which solves the problem that the rolling pace is seriously affected when a mill roll of the existing equipment is changed. The turnable puncher top centering roll device comprises a pair of turnable oil cylinder permanent seats (3) arranged at the top end of a puncher frame (1) and upper hinge shafts (4); a pair of turnable shaft core permanent seats (10) are arranged on the puncher frame (1) above a top centering roll frame (2); turnable shafts (11) are arranged on the turnable shaft core permanent seats (10); an upper hinge hole seat (12) is arranged at the right end on the top surface of the top centering roll frame (2); a right hinge hole seat (9) is arranged on the right side surface of the top centering roll frame (2); a right hinge shaft (8) is arranged in the right hinge hole seat (9); the upper hinge shafts (4) penetrates through a bottom end lug ring (5) of an oil cylinder (6); and a shaft end lug ring of an output shaft (7) of the oil cylinder (6) and the right hinge shaft (8) are strung together. The turnable puncher top centering roll device realizes mill roll rapid replacement and opening degree automatic adjustment.
Description
Technical field
Patent of the present invention relates to centering roller device in a kind of novel machine, particularly centering roller device in the machine in a kind of seamless steel pipe hot-rolling production line perforation unit.
Background technology
At present, centering roller device mainly comprises in the domestic general machine: hydraulic cylinder, three swing-bar mechanisms, three Centering Rolls, two cover linkages, frame and lift form.Its installation is first centering roller device in the machine to be hung on main frame plane rail and V-type rail by crane, dialled in by one section on backstage and to transfer to hydraulic cylinder in the device to dial in installation position in the punch main frame, make after the inclined-plane on the centering roller frame is adjacent in inclined-plane on the main frame and the machine, with the pull bar that is installed in main frame centering roller device in the machine is fixed on the main frame again.When needs change roll, dialling in the hydraulic cylinder of transfering in the device by one section on backstage dials out to it outside main frame, then hung away by crane, after finishing, roll to be changed hung on main frame plane rail and V-type rail by crane again, transfer to the device hydraulic cylinder to dial in the main frame installation position by dialling in, strained by pull bar.The defective that exists: the one, because when changing roll, the centering roller device spended time is many in the lifting machine, affect production output, require more and more sooner for modern Steel Tube Industry rolling rhythm, the efficient requirement is high, can not satisfy its requirement; The 2nd, need the manual adjustments lift to adjust the opening degree size that three Centering Rolls form during the pipe of rolling different size, to realize the guiding of different size hollow billet, to adjust slowly, cost manpower and time are many, and the opening degree size adjustment is inaccurate; The 3rd, because causing in main frame casting complexity, the machine, this structure on the centering roller frame inclined-plane and V-type face processing difficulties are arranged, cost is high; And the centering roller device center easily causes push rod crooked inaccurate with centering, the influence of rolled quality away from the host center line position in the formation machine.
Summary of the invention
The invention provides a kind of turnover piercing mandrel plug centering roller device, solved existing equipment need to be with machine when need changing roll in centering roller device dial in the technical problem of the influence of rolled rhythm that dial-out brings.
The present invention is by the above problem of following solution:
A kind of turnover piercing mandrel plug centering roller device, comprise the piercing mill housing and top Centering Roll frame, be provided with a pair of overturning oil cylinder holder on the top of the piercing mill housing, be provided with hinge at the overturning oil cylinder holder, the piercing mill housing above the Centering Roll frame of top is provided with a pair of upset axle center holder, holder is provided with trip shaft in the upset axle center, end face upper end in top Centering Roll frame is provided with the hinge hole seat, right flank in top Centering Roll frame is provided with right hinge hole seat, in right hinge hole seat, be provided with right hinge, the bottom earrings cross-under of oil cylinder is on upper hinge, and the axle head earrings of the output shaft of oil cylinder and right hinge cross-under are together.
Between the lower end that comes directly towards the Centering Roll frame and the piercing mill housing, be provided with set bolt, be provided with displacement transducer at the driving oil cylinder that comes directly towards Centering Roll.
The present invention has realized the quick-replaceable roll and has automatically regulated the requirement of opening degree size, prevents the bending of push rod, has realized accurate centering, has improved product yield and quality, and simple in structure, and control is convenient.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of right apparent direction of the present invention.
The specific embodiment
A kind of turnover piercing mandrel plug centering roller device, comprise the piercing mill housing 1 and top Centering Roll frame 2, be provided with a pair of overturning oil cylinder holder 3 on the top of the piercing mill housing 1, be provided with hinge 4 at overturning oil cylinder holder 3, the piercing mill housing 1 above top Centering Roll frame 2 is provided with a pair of upset axle center holder 10, be provided with trip shaft 11 at upset axle center holder 10, end face upper end in top Centering Roll frame 2 is provided with hinge hole seat 12, right flank in top Centering Roll frame 2 is provided with right hinge hole seat 9, in right hinge hole seat 9, be provided with right hinge 8, bottom earrings 5 cross-under of oil cylinder 6 are on upper hinge 4, and the axle head earrings of the output shaft 7 of oil cylinder 6 and 8 cross-under of right hinge are together.
Between the lower end that comes directly towards Centering Roll frame 2 and the piercing mill housing 1, be provided with set bolt 13, be provided with displacement transducer at the driving oil cylinder that comes directly towards Centering Roll.
The present invention does not need centering roller device in the machine is placed on plane and the V-arrangement face, and be adjacent to without the inclined-plane, solved main frame casting complicated and the inclined-plane above the Centering Roll frame and V-arrangement face processing difficulties problem, reduced cost, and shortened the distance of the interior centering roller device center of machine from the host center line, prevented that push rod is crooked, has improved rolling quality.When changing roll, take first by needs the set bolt 13 that is locked on the Centering Roll frame apart, set bolt 13 is rotated to Centering Roll frame opposite location throws off itself and Centering Roll frame, the retraction of roll change hydraulic cylinder piston club head is driven the Centering Roll frame, centering roller device in the machine after being rotated into horizontal position, vertical position is maintained static, can change roll, behind the complete roll to be changed, roll change hydraulic cylinder piston club head stretches out drive Centering Roll frame and is returned to original position, then set bolt 13 is rotated to connecting position the Centering Roll rack locking is got final product.
The invention solves the interior centering roller device of existing punch machine exists roll changing time long; Manual adjustments three roller opening degrees cost manpower and time are many, and regulate inaccuracy; Main frame casting is complicated, centering roller frame processing difficulties in the machine, cost is high and the frame of disembarking far easily cause push rod crooked and feel relieved inaccurate, the problem of influence of rolled quality.
