Abstract
The utility model discloses a press-down balancing device of a turning hub type straightening machine. The press-down balancing device of the turning hub type straightening machine solves the problems that a mechanical balancing device of an existing device is not high in balancing reliability. The press-down balancing device comprises a worm wheel (10), a hollow screw rod (8) a tubular hydraulic cylinder base (15), a hollow hydraulic cylinder (16), a hemispherical groove (4), an inner cavity boss (7) and a balancing through hole (3). The worm wheel (10) is arranged on a worm and gear speed reducer (14) and is provided with a through hole (9) with screw threads. The hollow screw rod (8) is connected in the through hole (9) in a threaded mode. The tubular hydraulic cylinder base (15) and the hollow hydraulic cylinder (16) are fixedly arranged on the worm and gear speed reducer (14). The hemispherical groove (4) is formed in the top face of a turning hub (2). The inner cavity boss (7) is arranged in an inner cavity of the turning hub (2). The balancing through hole (3) is formed between the hemispherical groove (4) and the inner cavity boss (7). An inverted T-shaped balancing shaft (5) penetrates through the balancing through hole (3) and a middle hole of the hollow screw rod (8) from bottom to top in sequence, and then is connected with an output shaft (17) of the hollow hydraulic cylinder (16). The bottom end of the hollow screw rod (8) abuts against the hemispherical groove (4). The press-down balancing device of the turning hub type straightening machine is adjustable in balance force, and easy to install and overhaul.
Description
Technical field
The present invention relates to a kind of smelter seamless steel pipe production, particularly the hold-down and balancing device on a kind of rotary hub type straightener of producing minor diameter tubing.
Background technology
Tube bending degree after hot rolling or the heat treatment is bigger, can not directly use as production tube, for satisfying instructions for use, needs to carry out online or the off-line aligning to steel pipe.Rotary hub type straightener is a kind of of straightener, and its main frame chief component has: frame, smoothing roll, hold-down and balancing device, press bascule and up-down rollers adjusting device etc.The adjustment of existing smoothing roll roll gap is that pressured bascule is down realized; the adjustment of hold-down and balancing device is finished under non-aligning state; hold-down and balancing device is made up of leading screw, screw, commentaries on classics hub and transmission device thereof etc.; because having thread pitch between leading screw and screw; need to eliminate thread pitch; usually unit employing mechanical equilibrator is eliminated the gap, but the mechanical balance reliability is not high, installation, adjustment, maintenance inconvenience.
Summary of the invention
The invention provides a kind of rotary hub type straightener hold-down and balancing device, it is high and install and adjust all inconvenient technical problems of maintenance to have solved balance reliability that mechanical equilibrator that existing equipment adopts exists.
The present invention overcomes the above problems by following scheme:
A kind of rotary hub type straightener hold-down and balancing device, comprise frame, be respectively arranged with drive motors and worm-gear speed reducer in frame, the worm screw that arranges at worm-gear speed reducer is connected with the output shaft of drive motors, the worm gear that arranges on the worm-gear speed reducer is provided with the through hole of band screw thread, cored screw is screwed onto in the through hole, be set with tubular hydraulic cylinder seat at worm-gear speed reducer, tubular hydraulic cylinder seat is provided with the hollow hydraulic cylinder, the output shaft that passes the hollow hydraulic cylinder outputs to downwards in the mesopore of tubular hydraulic cylinder seat, the end face that changes hub is provided with hemispherical groove, in the inner chamber that changes hub, be provided with the inner chamber boss, between hemispherical groove and inner chamber boss, be provided with the balance through hole, the inverted T-shaped trunnion shaft is connected with the output shaft of hollow hydraulic cylinder after passing the mesopore of balance through hole and cored screw from bottom to top successively, the bottom T shape platform of inverted T-shaped trunnion shaft and the bottom apical grafting of inner chamber boss together, the bottom of cored screw and hemispherical groove apical grafting are together.
Be set with smoothing roll in the bottom of changeing hub.
Equilibrant force of the present invention is adjustable, is easy to install and maintenance, can better eliminate thread pitch, and screw rod adopts separate type with changeing hub, and both spheres contacts prevent in changeing the hub adjustment process damage to worm-gear speed reducer.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation that the vertical axis direction is cut open about the present invention edge.
The specific embodiment
A kind of rotary hub type straightener hold-down and balancing device, comprise frame 13, be respectively arranged with drive motors 12 and worm-gear speed reducer 14 in frame 13, the worm screw 11 that arranges at worm-gear speed reducer 14 is connected with the output shaft of drive motors 12, the worm gear 10 that arranges on the worm-gear speed reducer 14 is provided with the through hole 9 of band screw thread, cored screw 8 is screwed onto in the through hole 9, be set with tubular hydraulic cylinder seat 15 at worm-gear speed reducer 14, tubular hydraulic cylinder seat 15 is provided with hollow hydraulic cylinder 16, the output shaft 17 that passes hollow hydraulic cylinder 16 outputs to downwards in the mesopore of tubular hydraulic cylinder seat 15, the end face that changes hub 2 is provided with hemispherical groove 4, in the inner chamber that changes hub 2, be provided with inner chamber boss 7, between hemispherical groove 4 and inner chamber boss 7, be provided with balance through hole 3, inverted T-shaped trunnion shaft 5 is connected with the output shaft 17 of hollow hydraulic cylinder 16 after passing the mesopore of balance through hole 3 and cored screw 8 from bottom to top successively, the bottom T shape platform 6 of inverted T-shaped trunnion shaft 5 and the bottom apical grafting of inner chamber boss 7 together, the bottom of cored screw 8 and hemispherical groove 4 apical graftings are together.
Be set with smoothing roll 1 in the bottom of changeing hub 2.
Drive motors 12 drives commentaries on classics hub 2 by worm-gear speed reducer 14 drive screws 8 and moves up and down, and inverted T-shaped trunnion shaft 5 servo-actuated knee-actions are finished the roll gap adjustment of smoothing roll 1 different operating position simultaneously; For preventing that in changeing hub 2 adjustment processes to the damage of worm-gear speed reducer 14, screw rod 8 adopts separate type with changeing hub 2, both spheres contacts.
