Door-type holder vibration unit

Abstract

The invention provides a door-type holder vibration unit comprising a holder, a vibration frame, vibration generators and a vibration guide device. The vibration frame is mounted in the holder; the vibration guide device is fixed between the vibration frame and the holder; and the vibration generators are respectively mounted on the vibration frame and the holder. The door-type holder vibration unit is characterized in that: the lateral surface of the holder is in a U shape; a T-shaped door opening is arranged at the lower part of the front surface of the holder; the T-shaped door opening is internally provided with a lower plate spring and a vibration driving device, and the upper part is provided with a transverse groove with a movable frame and an upper plate spring. The vibration unit holder has high inherent frequency, and the vibration unit has the advantages of stable vibration, high strength, light weight and compact structure.

Description

technical field [0001] The invention relates to a crystallizer vibration device of a continuous casting machine, in particular to a door type fixed frame vibration unit. Background technique [0002] The purpose of crystallizer vibration is to facilitate "demoulding" and prevent the occurrence of breakout accidents caused by bonding between the billet and the copper wall of the mold during the solidification process. [0003] There are many types of slab crystallizer vibration devices. Currently, the vibration drive devices used in slab continuous casting machines are driven by mechanical vibration units and hydraulic vibration units. According to the vibration curves, there are sinusoidal vibration curves and non-sinusoidal vibration curves. The short-arm four-link type driven by the motor and the eccentric wheel driven by the motor are mechanical vibrations, and the amplitude, frequency and waveform cannot be adjusted online. The vibration accuracy is relatively low, and t...

Problems solved by technology

[0005] At present, there are two types of fixed frames for the hydraulic vibration unit of the slab crystallizer guided by the leaf spring. One is a solid structure, which is hollowed out at the place where the leaf spring and the vibration drive device are installed, and assembled after processing the mounting surface. This structure exists The structure is bulky, processing and installation require high precision, and it is difficult to adjust; the other is a thin plate structure, which is only reinforced at the position where the leaf spring and vibration drive device are installed. There are too many empty places, it is inconvenient to install and adjust the vibration unit, and the natural frequency of the fixed frame is low, which is easy to cause resonance when vibrating
