Description
Technical field
Patent of the present invention relates to centering roller arrangement in a kind of novel machine, particularly centering roller arrangement in the machine in a kind of seamless steel pipe hot-rolling production line perforation unit.
Background technology
At present, the centering roller arrangement mainly comprises in the domestic general machine: hydraulic cylinder, three swing-bar mechanisms, three centering rollers, two cover linkages, frame and lift are formed.Its installation is earlier centering roller arrangement 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 arrangement 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, hung away by crane then, 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, centering roller arrangement spended time is many in the lifting machine, influence production output, require more and more sooner for modern steel pipe industry rolling rhythm, efficient requires height, can not satisfy its requirement; The 2nd, need the manual adjustments lift to adjust the opening degree size that three centering rollers 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 inclined-plane and V-type face processing difficulties are arranged, the cost height on the centering roller frame; And centering roller arrangement center causes push rod crooked inaccurate with centering, the influence of rolled quality away from the host center line position easily in the formation machine.
Summary of the invention
The invention provides a kind of turnover piercing mandrel plug centering roller arrangement, solved the existing equipment roller arrangement of feeling relieved in need be with machine when needing to change roll and dialled in the technical problem of the influence of rolled rhythm that dial-out brings.
The present invention overcomes the above problems by following scheme:
A kind of turnover piercing mandrel plug centering roller arrangement, comprise punch frame and top centering roller frame, be provided with a pair of overturning oil cylinder holder on the top of punch frame, the overturning oil cylinder holder is provided with hinge, punch frame above the top centering roller frame is provided with a pair of upset axle center holder, upset axle center holder is provided with trip shaft, end face upper end at top centering roller frame is provided with the hinge hole seat, the right flank of top centering roller 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 last hinge, and the axle head earrings of the output shaft of oil cylinder and right hinge cross-under are together.
Be provided with set bolt between the lower end that comes directly towards the centering roller frame and punch frame, the driving oil cylinder of top centering roller is provided with displacement transducer.
The present invention has realized quick replacing roll and has regulated the requirement of opening degree size automatically, 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 arrangement, comprise punch frame 1 and top centering roller frame 2, be provided with a pair of overturning oil cylinder holder 3 on the top of punch frame 1, overturning oil cylinder holder 3 is provided with hinge 4, punch frame 1 above the top centering roller frame 2 is provided with a pair of upset axle center holder 10, upset axle center holder 10 is provided with trip shaft 11, end face upper end at top centering roller frame 2 is provided with hinge hole seat 12, the right flank of top centering roller 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 last 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.
Be provided with set bolt 13 between the lower end that comes directly towards centering roller frame 2 and punch frame 1, the driving oil cylinder of top centering roller is provided with displacement transducer.
The present invention does not need centering roller arrangement 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 roller frame and V-arrangement face processing difficulties problem, reduced cost, and shortened the distance of roller arrangement center from the host center line of feeling relieved in the machine, prevent the push rod bending, improved rolling quality.When changing roll, take by needs the set bolt 13 that is locked on the centering roller frame earlier apart, set bolt 13 is rotated to centering roller frame opposite location throws off itself and centering roller frame, the withdrawal of roll change hydraulic cylinder piston club head is driven the centering roller frame, centering roller arrangement in the machine after being rotated into the level position, vertical position is maintained static, can change roll, behind the intact roll to be changed, roll change hydraulic cylinder piston club head stretches out drive centering roller frame and is returned to original position, then set bolt 13 is rotated to the connection position roller frame locking of feeling relieved is got final product.
The invention solves the roller arrangement of feeling relieved in the 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 cause far easily push rod crooked and feel relieved inaccurate, the problem of influence of rolled quality.
