Abstract
The utility model discloses an online hot-state width-adjusting device which is arranged on a crystallizer tank. The device comprises a servo motor, the servo motor is connected with a cycloidal speed reducer through a key, the cycloidal speed reducer is fixedly connected with the shaft end of a ball-screw pair through a key, a nut of the ball-screw pair is fixedly connected with a casing pipe through a key, and the casing pipe is connected with a crystallizer narrow-face inserter through a spherical twist joint device; and a lead screw of the ball-screw pair rotates so as to drive a nut of the ball-screw pair to rotate, and the nut of the ball-screw pair drives the casing pipe to make a linear motion. Because the casing pipe is connected with the crystallizer narrow-face inserter through the spherical twist joint device, the online hot-state width-adjusting device disclosed by the utility model is simple in structure, short in transmission chain, small in mechanical clearance and high in width-adjusting size precision, and can realize the accurate control of online hot-state width adjusting and prevent the width-adjusting size from drifting in the process of casting.
Description
Technical field
The utility model belongs to a kind of metallurgical continuous casting equipment of field shaping technique, particularly a kind of online hot Width adjusting device.
Background technology
Crystallizer is the strand former in the continuous casting steel machine, its function be with the high-temperature molten steel that continuously injects its inner chamber through forcing cooling, make it the strand that solidify out into gradually has desired section configuration and shell thickness.Because it is different that the client requires the continuous casting steel billet width specifications, thereby need the adjustment mould at narrow, the mould at narrow Width adjusting device is the equipment on the narrow limit of adjustment conticaster.
Along with the management of iron and steel enterprise is constantly progressive; The quality of product and automatic control level are required also increasingly high, to the requirement of mould at narrow Width adjusting device: the reliable strict locking in position behind high reliability, remote control and regulation, on-line monitoring, dynamic compensation, positive and negative two-way accurate adjustment location, the location, narrow limit tapering is stable and drift value is small.
There are a series of problems in the Width adjusting device that uses at present.At first, the Width adjusting device of trapezoidal screw nut structure is because the trapezoidal screw nut exists the gap bigger.The gap can increase under long-time larger axial force effect, thereby directly has influence on the axial location size of mould at narrow, and this phenomenon is called the tapering drift.The more important thing is to deposit between the worm and wheel of worm-gear speed reducer to be engaged on the gap, have influence on the axial location size of mould at narrow.
Above problem is the common problem of domestic steel mill, therefore presses for and will improve the existing mechanical Width adjusting device.
Summary of the invention
In order to overcome the defective of above-mentioned prior art, the purpose of the utility model is to provide a kind of online hot Width adjusting device, has easy to adjust, the reliable and stable stable and small characteristics of tapering drift value of auto-lock function, tapering that possess.
In order to reach above-mentioned existing purpose, the technical scheme of the utility model is achieved in that
A kind of online hot Width adjusting device; Be installed on the crystallizer water tank 9; Comprise servomotor 1, servomotor 1 is connected with gerotor reductor 3 through key 2, and gerotor reductor 3 is affixed with the axle head of ball screw assembly, 6 through key 4; The nut of ball screw assembly, 6 is affixed through key 7 and sleeve pipe 8, and sleeve pipe 8 is connected with crystallizer leptoprosopy insert 11 through ball twist joint device 10.
The utility model is simple in structure, and driving-chain is short, mechanical clearance is little, transfers wide dimensional accuracy high, can realize the accurate control that online hot accent is wide, prevents to transfer wide size drift in casting cycle, to occur.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
The specific embodiment
Be described in detail below in conjunction with the structural principle and the operation principle of accompanying drawing the utility model.
With reference to accompanying drawing; A kind of online hot Width adjusting device is installed on the crystallizer water tank 9, comprises servomotor 1; Servomotor 1 is connected with gerotor reductor 3 through key 2; Gerotor reductor 3 is affixed with the axle head of ball screw assembly, 6 through key 4, and the nut of ball screw assembly, 6 is affixed through key 7 and sleeve pipe 8, and sleeve pipe 8 is connected with crystallizer leptoprosopy insert 11 through ball twist joint device 10.
The operation principle of the utility model is: the nut of the moving lead screw pair 6 of the leading screw rotating band of ball screw assembly, 6 rotates, and the nut of thick stick secondary 6 drives sleeve pipe 8 and does rectilinear motion, because sleeve pipe 8 is connected with crystallizer leptoprosopy insert 11 through ball twist joint device 10.Servomotor 1 drives the position adjustment that gerotor reductor 2 can be realized the mould at narrow copper coin.In the servomotor 1 encoder can be installed, the location parameter of leading screw can be provided for the control system, servomotor 1 matching coding device can be realized remote control and regulation, on-line monitoring, dynamic compensation, accurate positive and negative two-way positioning function.
Among the figure: the 1-servomotor; The 2-key; 3-gerotor reductor; The 4-key; The 5-bearing block; The 6-ball screw assembly; The 7-key; The 8-sleeve pipe; 9-crystallizer water tank; 10-ball twist joint device; 11-crystallizer leptoprosopy insert.
