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 [0001] The invention relates to a seamless steel pipe production equipment for a metallurgical enterprise, in particular to a pressing balance device on a hub-type straightening machine for producing small-diameter pipes. Background technique [0002] The steel pipe after hot rolling or heat treatment has a large curvature and cannot be used directly as a finished pipe. In order to meet the use requirements, the steel pipe needs to be straightened on-line or off-line. The rotary hub type straightening machine is a kind of straightening machine. The main components of the main machine are: frame, straightening roller, pressing balance device, pressing balancing device and upper and lower roller adjustment device, etc. The adjustment of the existing straightening roller gap is realized by pressing the balance device. The adjustment of the pressing balance device is completed in the non-straightening state. The pressing balance device is composed of a screw, a...
