Description

Vibration absorber for vibrating table with compensation performance

technical field

The utility model relates to a vibration absorber, in particular to a vibration absorber for a vibrating table with compensation performance.

Background technique

The vibrating table is a commonly used equipment for the production of steel blanks. It includes the vibrating table for the special-shaped billet continuous casting machine and the non-sinusoidal mold vibrating table for the slab continuous casting machine. It is widely used in the mold vibration process required for the continuous casting of steel billets. During continuous casting, mold vibration is very effective in improving the lubrication between the strand and the mold interface. Due to the introduction of the invention of the vibrating crystallizer, the large-scale application of continuous casting technology in industry can be realized. It can be said that mold vibration is a prerequisite for successful pouring and an important milestone in the development of continuous casting.

In the general vibration table installation, it is necessary to install a pipeline vibration elimination device on the vibration table, which is of great significance to the reliability and stability of the vibration table. At present, the pipeline vibration elimination device of the vibrating table is connected by an ordinary 90° compound metal hose, as shown in Figure 1 and Figure 2, which includes a metal hose 101 and an outer braided mesh sleeve 102, and the shock absorber 90 The bending connecting pipe 2 and the flange 3 located at the outer end of the shock absorbing tube; the vibrating table has the characteristics of large horizontal and vertical amplitudes. It does not have longitudinal and horizontal stretching performance, and because it has no ability to resist vibration, the general actual use period is only about half a month, and the expensive maintenance costs and maintenance frequency bring huge losses to production.

Utility model content

The purpose of the utility model is to provide a vibration absorber for a vibration table with compensation performance, which has the advantages of strong shock absorption performance, long service life, compactness and practicality.

The utility model is achieved in this way, a shock absorber for a vibration table with compensation performance, which includes a connecting flange at the end and a turning connecting pipe at the middle, characterized in that the connecting flange and A compound damping pipe composed of double bellows is connected between the turning connecting pipes. The composite damping tube includes a first bellows and a second bellows, and the first bellows and the second bellows are parallel structures. The vertical and horizontal compensation amounts of the shock absorber are 30mm and 20mm respectively.

Preferably, the first bellows and the second bellows are both made of 0.8mm 304 stainless steel plate material; the first bellows and the second bellows are hydraulically formed.

Preferably, the turning connecting pipe is a right-angle smooth turning structure.

The beneficial effects of the utility model are: the vibration absorber disclosed by the utility model compensates and eliminates the vibration waves from the vibrating table through its excellent longitudinal and transverse stretchability, has a long service life, and has a good vibration elimination effect, making the vibration absorber Repair costs and frequency are greatly reduced, reducing the impact of shaker maintenance on production.

Detailed ways

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model will be further described.

As shown in Fig. 3 and Fig. 4, the utility model is realized in such a way that the shock absorber for a vibrating table with compensating performance includes a connecting flange 3 at the end and a turning connecting pipe 2 at the middle, which The structure is that the double bellows is connected between the connecting flange 3 and the turning connecting pipe 2 to form a compound damping pipe 1 . Preferably: the composite damping tube 1 includes a first bellows 101 and a second bellows 102, the first bellows 101 and the second bellows 102 are in parallel structure, and the turning connection between the two composite damping tubes 1 Tube 2 is a right-angle smooth transition structure. Through the compound shock absorber 1 with double bellows structure, the shock absorber has longitudinal and transverse expansion and contraction properties for the vibration waves from the vibrating table, and it can eliminate the vibration through compensation. The vertical and horizontal compensation amounts of the shock absorber are respectively It is 30mm and 20mm, which can well meet the vibration elimination requirements of the existing vibration table.

And, the more preferred design structure of the compound damping tube 1 is: the first bellows 101 and the second bellows 102 are made of 0.8mm 304 stainless steel plate material; and the first bellows 101 and the second bellows 102 are Hydroforming. By changing the original metal hose netting part into a 0.8mm thick 304 stainless steel plate, and a two-layer metal bellows formed by hydraulic pressure, the composite damping tube 1 has a good performance with the transmission of vibration waves. Excellent longitudinal and lateral stretchability, and good flexibility, the vibration is eliminated through compensation.

When the vibration absorber for the vibration table is actually used, the original half-month service life can be extended to three months, and the service life of the device has been increased by six times, which greatly reduces the maintenance cost and frequency of the vibration absorber, and reduces maintenance costs. Economic loss caused by delays affecting production efficiency. When in use, the flange 3 at both ends of the shock absorber is installed and connected, the overall installation is simple and fast, and the operation is easy. After actual use, it has the characteristics of strong shock absorption performance and long service life.
