Problems solved by technology

However, in practical applications, the servo hydraulic cylinder has the disadvantages of complex system, large amount of maintenance, and high input price; the disadvantage of the servo electric cylinder is that the electric cylinder composed of a servo motor driven ball or roller screw, the crystallizer The up and down vibration is achieved by the frequent forward and reverse rotation of the servo motor. The wear of the ball or roller screw is inevitable. Therefore, it is necessary to add a thin oil lubrication station to lubricate the ball or roller screw. The input price is also low. High, and the workload of repairing the electric cylinder is not small, the vibrating arm must meet certain requirements, so it is subject to certain restrictions in popularization and application

Abstract

The invention discloses a vibration generating device for changing the vibration amplitude of a continuous casting crystallizer through an eccentric wheel. The vibration generating device comprises avibration arm. The vibration arm is connected with one end of a connecting rod, the other end of the connecting rod is connected with an eccentric part of the eccentric wheel, and the eccentric wheelis connected with a drive device. The drive device comprises a motor, and an output shaft of the motor is rigidly connected with the rotary center of the eccentric wheel. The drive device drives the eccentric wheel to rotate in a reciprocating manner forwards and reversely, the eccentric wheel drives one end of the vibration arm to move through the connecting rod, and the other end of the vibration arm drives the continuous casting crystallizer to vibrate. The maximum rotating angle of the eccentric wheel decides the vibration amplitude of the continuous casting crystallizer. The motor drivesthe eccentric wheel to swing back and forth, so that vibration of the vibration arm is achieved; and the movement trail of the eccentric wheel is decided by the vibration amplitude of the vibration arm, so that the vibration amplitude of the vibration arm is modified at will according to actual requirements. The invention further discloses a method for changing the vibration amplitude of the continuous casting crystallizer.

Description

technical field [0001] The invention relates to a vibration generating device of a mechanical continuous casting crystallizer, in particular to a vibration generating device for changing the amplitude of the continuous casting crystallizer through an eccentric wheel. The invention also relates to a method for varying the vibration amplitude of a continuous casting mold. Background technique [0002] Mold vibration is one of the core technologies of continuous steel casting, and the device for generating mold vibration is the heart part of mold vibration. At present, there are roughly three types of devices for generating mold vibration in the continuous casting industry: [0003] 1. Mechanically driven sinusoidal vibration generating device; [0004] 2. Mold vibration generator driven by servo hydraulic cylinder; [0005] 3. The crystallizer vibration generator driven by the servo electric cylinder. [0006] The first type of vibration generating device is composed of AC...
