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 heat treatment is larger, can not directly as production tube, use, and for meeting instructions for use, need carry out online or 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 to realize by hold-down and balancing device; the adjustment of hold-down and balancing device completes under non-aligning state; hold-down and balancing device by leading screw, screw, turn hub and transmission device thereof etc. and form; because there is thread pitch between leading screw and screw; need to eliminate thread pitch; conventionally unit employing mechanical equilibrator is eliminated gap, but 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 overcomes the above problems by following scheme:
a kind of rotary hub type straightener hold-down and balancing device, comprise frame, in frame, be respectively arranged with drive motors and worm-gear speed reducer, the worm screw arranging on worm-gear speed reducer is connected with the output shaft of drive motors, on the worm gear arranging, be provided with the through hole with screw thread on worm-gear speed reducer, cored screw is screwed onto in through hole, on worm-gear speed reducer, be fixedly installed tubular hydraulic cylinder seat, on tubular hydraulic cylinder seat, be provided with hollow hydraulic cylinder, output shaft through hollow hydraulic cylinder outputs to downwards in the mesopore of tubular hydraulic cylinder seat, be provided with hemispherical groove turning on the end face of hub, in turning the inner chamber of hub, be provided with inner chamber boss, between hemispherical groove and inner chamber boss, be provided with balance through hole, inverted T-shaped trunnion shaft is connected with the output shaft of hollow hydraulic cylinder after the mesopore through balance through hole and cored screw from bottom to top successively, the bottom T shape platform of inverted T-shaped trunnion shaft is together with the apical grafting of the bottom of inner chamber boss, the bottom of cored screw is together with hemispherical groove apical grafting.
in the bottom that turns hub, be fixedly installed smoothing roll.
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 the damage to worm-gear speed reducer in turning hub adjustment process.
Accompanying drawing explanation
fig. 1 is structural representation of the present invention;
fig. 2 is the structural representation that the present invention cuts open along upper and lower vertical axis direction.
the specific embodiment
