[0027] The technical solution of the utility model is described in detail below in conjunction with specific embodiments:

[0028] Specifically, in a specific embodiment of the present utility model, one end of the first leaf spring 4 is fixed to the vibration table 1, and the other end is fixed to the vibration base 2.

[0033] Specifically, in the specific embodiment of the utility model, the first leaf spring 4 and the second leaf spring 6 have the same size specifications. Among them, the cross-section of the first leaf spring 4 and the second leaf spring 6 can be a trapezoidal cross-section shape, so that when the leaf spring is subjected to pressure, the stress can be better dispersed and the bearing capacity of the leaf spring can be improved. More specifically, the cross-section of the first leaf spring 4 and the second leaf spring 6 is an isosceles trapezoid, so that the elastic coefficients in the vertical and horizontal directions are relatively close, so that the force performance of the leaf spring in different directions is more balanced.

[0034] Specifically, in the specific embodiment of the utility model, the distances between the pin holes at both ends of the first leaf spring 4 and the second leaf spring 6 are the same.

[0037] To be more specific, continuous casting production is an advanced steel production technology. Its basic principle is to pour liquid steel into a continuous casting machine with cooling water. Under the condition of automated control, the cooling water is continuously circulated to make the molten steel gradually solidify and form billets, and finally the required steel is obtained. Continuous casting technology is widely used in many steel industries such as pipe making, wire, plate, strip steel and alloy steel. It can produce seamless steel pipes, welded steel pipes, hot-rolled wire, plate, cold-rolled strip steel, hot-rolled strip steel, galvanized strip steel, high-strength alloy steel and other products.

[0038] In the production process of the continuous casting machine in the prior art, the vibration tables currently used will have different degrees of polarization. Polarization can cause various product quality problems such as transverse cracks and angular cracks in the ingot, and even production accidents such as steel leakage. Polarization problem of vibration device The vibration devices currently used do not have a special anti-polarization mechanism. The single-cylinder driven or double-cylinder four-link vibration table controls the polarization amount by controlling the length of the connecting rod and the bearing clearance on both sides of the vibration. After the vibration device has been used for a period of time, the bearing clearance becomes larger and the polarization amount is bound to increase. The four-cylinder or multi-cylinder vibration device relies on the vibration accuracy of the electric cylinder or hydraulic cylinder to control the polarization. Therefore, the polarization amount of the vibration device depends on the manufacturing and control accuracy of the electric cylinder or electro-hydraulic cylinder. When one of the four cylinders or multiple cylinders fails or has a control error, polarization is also inevitable.

[0039] The anti-polarization mechanism for the continuous casting vibration device involved in the utility model can be installed on the inner arc side or the outer arc side of a single-cylinder, double-cylinder or multi-cylinder vibration table, or installed on the inner arc side and the outer arc side at the same time. The device can greatly reduce the polarization amount, so that the polarization amount of the vibration table is reduced by the influence of bearing wear and drive component control error.

[0040] The utility model relates to an anti-polarization mechanism for a continuous casting vibration device, which comprises: a vibration table 1, a vibration base 2, a first leaf spring upper support 3, a first leaf spring 4, a second leaf spring upper support 5, a second leaf spring 6, a first leaf spring lower support 7, a second leaf spring lower support 8, and a leaf spring adjustment bolt assembly 9. The first leaf spring lower support 7 and the second leaf spring lower support 8 are installed on the vibration base 2; the first leaf spring upper support 3 and the second leaf spring upper support 5 are installed under the vibration table 1. One end of the first leaf spring 4 is connected to the first leaf spring lower support 7 by bolts and a pin, and the other end is connected to the first leaf spring upper support 3 by bolts and a pin. Similarly, one end of the second leaf spring 6 is connected to the second leaf spring lower support 8 by bolts and a pin, and the other end is connected to the second leaf spring upper support 5 by bolts and a pin.

[0041] Among them, the first leaf spring 4 and the second leaf spring 6 are the same leaf springs, with the same size, the same material, and the same distance between the pin holes at both ends. The processing surfaces of the first leaf spring upper support 3 and the second leaf spring upper support 5 for installing the leaf springs are parallel and have the same processing surface size; the processing surfaces of the first leaf spring lower support 7 and the second leaf spring lower support 8 for installing the leaf springs are parallel and have the same processing surface size. In addition, the distance between the processing surfaces of the first leaf spring upper support 3 and the second leaf spring upper support 5 for installing the leaf springs is equal to the distance between the processing surfaces of the first leaf spring lower support 7 and the second leaf spring lower support 8 for installing the leaf springs. During installation, ensure that the first leaf spring 4 and the second leaf spring 6 remain parallel, so that the first leaf spring 4 and the second leaf spring 6 form a flexible parallel four-link. When the vibration device vibrates, since the first leaf spring lower support 7 and the second leaf spring lower support 8 are fixed on the vibration base 2, and the first leaf spring upper support 3 and the second leaf spring upper support 5 are fixed on the vibration table 1, the vibration table is constrained by the first leaf spring 4 and the second leaf spring 6 to maintain horizontality, thereby realizing the function of preventing the vibration table from polarizing. That is, in the embodiment of the utility model, two groups of leaf springs of the same length and material are installed on the inner arc or outer arc side of the vibration table to form a flexible parallel four-bar linkage. The two groups of leaf springs are installed in parallel, one end of the leaf spring is fixed on the vibration base, and the other end is fixed on the vibration table surface. It can be installed on the inner arc side or outer arc side of a single-cylinder, double-cylinder or multi-cylinder vibration table, or on the inner arc side and the outer arc side at the same time. In summary, the anti-polarization mechanism for the continuous casting vibration device involved in the embodiment of the utility model can greatly reduce the polarization amount compared with the prior art, so that the polarization amount of the vibration table is reduced by the influence of bearing wear and drive component control error, thereby realizing the technical function of preventing the polarization of the vibration table surface, and having significant technical effects.
