Abstract
The invention discloses a rotating hub type under-pressure balancing device of a straightener and solves the problem about poor balancing reliability of existing mechanical balancing device of equipment. The rotating hub type under-pressure balancing device of the straightener is characterized in that a worm gear (10) arranged on a worm gear and worm speed reducer (14) is provided with a through hole (9) with a screw fastener, a hollow screw (8) is screwed in the through hole (9), a tubular hydraulic cylinder seat (15) and a hollow hydraulic cylinder (16) are fixedly arranged on the worm gear and worm speed reducer (14), a hemispherical groove (4) is reserved on the top surface of a rotating hub (2), a cavity boss (7) is arranged in an inner cavity of the rotating hub (2), a balance through hole (3) is reserved between the hemispherical groove (4) and the cavity boss (7), an inverted T-shaped balance shaft (5) sequentially penetrates through the balance through hole (3) and a central hole of the hollow screw (8) from bottom to top to be connected with an output shaft (17) of the hollow hydraulic cylinder (16), and the bottom end of the hollow screw (8) is abutted against the hemispherical groove (4). The rotating hub type under-pressure balancing device is adjustable in balance force and easy to mount and maintain.
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 narrow tube.
Background technology
Flexibility of steel pipe after hot rolling or the heat treatment is larger, 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 lower bascule is realized; the adjustment of hold-down and balancing device is finished under non-aligning state; hold-down and balancing device by leading screw, screw, turn hub and transmission device thereof etc. and form; 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, do not solved balance reliability that mechanical equilibrator that existing equipment adopts exists high and install and adjust all inconvenient technical problems of maintenance.
The present invention is by the above problem of following solution:
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 at worm-gear speed reducer is provided with the through hole with screw thread, cored screw is screwed onto in the through hole, be fixedly installed tubular hydraulic cylinder seat at worm-gear speed reducer, be provided with the hollow hydraulic cylinder at tubular hydraulic cylinder seat, the output shaft that passes the hollow hydraulic cylinder outputs to downwards in the mesopore of tubular hydraulic cylinder seat, be provided with hemispherical groove at the end face that turns hub, in turning the inner chamber of 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 passes the balance through hole from bottom to top successively is connected with cored screw and is connected with the output shaft of hollow hydraulic cylinder behind the mesopore, 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 fixedly installed smoothing roll in the bottom that turns 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 turning hub, and both sphere-contacts prevent in turning the hub adjustment process damage to worm-gear speed reducer.
