Description

Technical Field

[0001] The utility model relates to the technical field of casting equipment, in particular to a pump-controlled mold hydraulic vibration device and a continuous casting machine. Background Art

[0002] The mold hydraulic vibration device is the core equipment in the continuous casting machine. Molten steel solidifies into a billet in the mold. The mold is fixed on the vibration frame of the vibration device and reciprocates with the vibration frame. The vibration of the mold is equivalent to the demolding function, aiming to prevent the billet from sticking and causing drawing cracks or steel leakage, and at the same time can also improve the surface quality of the billet. The specific implementation process is as follows: The mold makes a reciprocating vibration motion. When the mold moves upward, the adhesion between the newly formed billet shell and the mold is reduced; when the mold moves downward, for a short period of time, its speed is slightly greater than the billet drawing speed, that is, negative slippage is formed, so that a compressive stress process is generated during the formation of the billet shell, and the billet shell with a tendency to break is pressed and combined in the mold. The quality of the billet and the normal operation of the equipment are directly related to the smoothness, accuracy and vibration waveform of the mold vibration.

[0003] At present, the commonly used hydraulic vibration is hydraulic servo vibration, and its structural composition consists of a vibration unit, a driving hydraulic cylinder, a servo valve and a hydraulic pump station. Hydraulic servo vibration uses an electro-hydraulic servo valve to control the hydraulic cylinder to achieve sinusoidal and non-sinusoidal vibrations, and can conveniently realize the on-line adjustment and monitoring of amplitude, frequency and waveform. However, due to the use of an electro-hydraulic servo valve, there are disadvantages such as high requirements for oil cleanliness, high construction operation and maintenance costs, and low efficiency.

[0046] Embodiment 1:

[0047] As Figures 1 to 4 shown, the present utility model provides a pump-controlled crystallizer hydraulic vibration device, which includes a connecting frame 10 and at least one vibration unit 11 provided on the connecting frame 10. The vibration unit 11 includes: a fixed frame 20 connected to the connecting frame 10; a vibrating frame 21 movably provided within the fixed frame 20; a guiding mechanism connected between the fixed frame 20 and the vibrating frame 21; and a driving mechanism 30 for driving the vibrating frame 21 to vibrate up and down relative to the fixed frame 20. The driving mechanism 30 has a housing connected to the fixed frame 20, and a servo motor 31, a two-way hydraulic pump 33 and a driving hydraulic cylinder 34 connected in sequence are provided within the housing. The cylinder rod of the driving hydraulic cylinder 34 is connected to the vibrating frame 21 for driving the vibrating frame 21 to vibrate up and down.

[0048] For the pump-controlled crystallizer hydraulic vibration device described in the present utility model, the two-way hydraulic pump 33 is directly driven by the servo motor 31 to supply high-pressure oil to the driving hydraulic cylinder 34, and the reciprocating motion of the driving hydraulic cylinder 34 is realized by the commutation of the servo motor 31, avoiding the pressure loss of the workshop pipelines and servo valves, and having the advantage of saving electric energy.

[0049] The hydraulic vibration device of the pump-controlled mold according to the present utility model realizes the integration of the hydraulic drive system in the drive mechanism 30, cancels the huge hydraulic pump station system, servo valves, etc. in the existing products, eliminates the influence of the oil cleanliness problem on vibration, avoids the problem of servo valve blockage, and improves production efficiency.

[0050] The following will describe in detail the specific structures of the various parts of the hydraulic vibration device of the pump-controlled mold according to the present utility model, as well as the connection relationships between the various parts.

[0051] As Figure 1 and Figure 4 shown, the hydraulic vibration device of the pump-controlled mold according to the present utility model has a connecting frame 10 and a vibration unit 11, and the vibration unit 11 is installed on the connecting frame 10. The connecting frame 10 is a steel plate with a predetermined shape, and the vibration unit 11 can be connected to the connecting frame 10 by means of bolt connection.

[0052] Preferably, as Figure 4 shown, two opposite vibration units 11 are installed on the connecting frame 10, and the two vibration units 11 are spaced apart longitudinally along the connecting frame 10. One of the two vibration units 11 serves as an inner arc vibration unit, and the other serves as an outer arc vibration unit, and an arc-simulating movement can be realized. By making the amplitudes of the two vibration units 11 different to realize the arc-simulating movement, the amplitude of the inner arc vibration unit is smaller than that of the outer arc vibration unit, that is: the vibration unit 11 with a smaller amplitude serves as the inner arc vibration unit, and the vibration unit 11 with a larger amplitude serves as the outer arc vibration unit 11.

Under the drive of the drive hydraulic cylinder 34 and simultaneously under the guidance of the guiding mechanism, the vibration frame 21 can vibrate up and down relative to the fixed frame 20.

[0055] As Figure 3As shown in the figure, the drive mechanism 30 includes a housing, a servo motor 31, a two-way hydraulic pump 33, and a drive hydraulic cylinder 34. Among them, the housing is composed of a mounting plate 35 and a protective plate 36. The mounting plate 35 is connected to the fixed frame 20 by bolts. An installation space is formed between the mounting plate 35 and the protective plate 36. The servo motor 31, the two-way hydraulic pump 33, and the drive hydraulic cylinder 34 are all arranged in this installation space. The output shaft of the servo motor 31 is connected to the two-way hydraulic pump 33 through a coupling 32, which is used to drive the two-way hydraulic pump 33 to rotate and output high-pressure oil pressure. The two-way hydraulic pump 33 is connected to the drive hydraulic cylinder 34 through a pipeline, so as to realize the telescopic movement of the piston rod of the drive hydraulic cylinder 34. The output end of the piston rod is connected to the vibration frame 21 to drive the vibration frame 21 to vibrate up and down.
