Abstract

A vibrating device for a crystallizer comprises a fixed beam, a vibrating table and servo cylinders. The vibrating device is characterized in that the vibrating table is connected with the fixed beam through an upper connecting rod and connected with servo cylinders through a lower connecting rod; the lower connecting rod is a cranked lever; and the turning point part of the lower connecting rod is connected with the fixed beam. In the vibrating device, the vibrating table and the crystallizer are driven by a connecting rod mechanism; the sinusoidal and non-sinusoidal arc-imitated vibrations of the crystallizer and the single-cylinder drive are realized by controlling the angles of the connecting rods; the hydraulic servo cylinder can be accessibly interchanged with the electric servo cylinder; and the arc-imitated precision and the vibrating precision are improved. In addition, the vibrating device has the advantages of simple structure, low cost, safety, reliability and good stability, is helpful to prolong the service lives of the servo cylinders.

Technical field

The utility model is applied to little square-round billet continuous casting machine engineering, relates to a kind of mould vibration device.

Background technology

Mould vibration device is a kind of visual plant in the conticaster.In order to prevent from crystallizer, to cohere with copper coin the process of setting and drawing crack or bleedout accident occur sticking from the molten steel that pans flow down; and be convenient to mould adobe blocks; crystallizer drives by vibrating device and makes periodic vibration according to oscillating curve; change the relative position of molten steel face and crystallizer wall; simultaneously, cohere by adding the covering slag minimizing.The more employing twin-tub of existing vibrating device drives, the structure more complicated, and cost is higher.

The utility model content

The purpose of this utility model is to provide a kind of mould vibration device simple in structure.

The purpose of this utility model is to realize like this, a kind of mould vibration device, comprise built-in beam, shake table and servoBcylinder, it is characterized in that: described shake table is connected with described built-in beam by last connecting rod, be connected with described servoBcylinder by lower link, described lower link is that curved bar and its flex point place are connected with described built-in beam.

An above-mentioned end and the above-mentioned shake table of going up connecting rod is hinged on hinge A place, the other end and said fixing beam are hinged on hinge B place, one end of above-mentioned lower link and described shake table are hinged on hinge C place, above-mentioned flex point place and described built-in beam are hinged on hinge D place, and the intersection point of the line of the line of described hinge A, hinge B and hinge C, hinge D is the center of circle of the basic radius of conticaster.This structure can guarantee that crystallizer imitates arc along the basic radius of conticaster and move, and improves the vibration precision, and makes vibration steadily, and is safe and reliable.

For by regulating the gap that produces after the long-term operation of compensation vibration device, avoid the influence of gap to the vibration precision, guarantee the long-term accuracy of vibrating device, the jointed shaft at above-mentioned hinge A place adopts eccentric shaft.

Above-mentioned servoBcylinder is arranged on inner arc and peripheral hardware protective cover.

For whole drive unit and outside adverse circumstances are isolated, guarantee that servoBcylinder moves in good environment, improve the life-span of servoBcylinder, adopt the compressed air sealing protection in the above-mentioned protective cover.

In order to slow down vibration, reduce the load of drive unit, be provided with buffer unit between above-mentioned shake table and the built-in beam.

Above-mentioned buffer unit is a spring.

Above-mentioned servoBcylinder can be hydraulic servo cylinder, also can be the electrical servo cylinder.

The utlity model has following beneficial effect, the utility model drives shake table and crystallizer by linkage, and the imitative arc vibration of angle realization crystallizer by control link comprises sine and non-sinusoidal oscillation, realized the single cylinder driving simultaneously, and hydraulic servo cylinder and electrical servo cylinder can accessiblely exchange, and have not only improved precision of simulated arc and vibration precision, and simple in structure, cost is low, safe and reliable, good stability, and help prolonging life-span of servoBcylinder.
