Description

Technical Field

[0001] This application relates to the field of crystallizers, and more particularly to a vibration mechanism for crystallizers. Background Technology

[0002] The crystallizer is the billet forming equipment in continuous steel casting and is the core component of the continuous casting machine. If the crystallizer remains stationary, the billet will break or crack, resulting in scrap. A crystallizer vibration device can support the crystallizer and drive it to vibrate up and down at a given amplitude and frequency, making demolding easier and preventing the billet from sticking to the water-cooled wall of the crystallizer during solidification, thus preventing billet breakage. A commonly used leaf spring vibration device replaces the guide arm on the short-arm four-bar linkage with a spring plate, eliminating the need for four bearings and lubrication, effectively improving the horizontal misalignment problem of the vibration device. Simultaneously, a balance spring is used in the mechanism for buffering and balancing the load. However, these types of vibration devices mostly use an electric motor for power transmission, resulting in a complex structure, complicated disassembly and maintenance, large footprint, and high cost.

The first T-shaped vibration frame 5 has a T-shaped structure and is positioned above the first fixed frame 3 and the first positioning seat 2. The bottom two sides of the middle end of the first T-shaped vibration frame 5 are respectively hinged to the middle of the two first leaf springs 4. The second T-shaped vibration frame 6 has a T-shaped structure and is positioned above the second fixed frame and the second positioning seat. The bottom two sides of the middle end of the second T-shaped vibration frame 6 are respectively hinged to the middle of the two second leaf springs. One end of the first vibration arm 7 is hinged to the upper part of the first fixed frame 3, and the other end is hinged to one end of the connecting beam 9. The middle part of the first vibration arm 7 is hinged to the upper part of the middle end of the first T-shaped vibration frame 5. One end of the second vibration arm is hinged to the upper part of the second fixed frame, and the other end is hinged to the other end of the connecting beam 9. The middle part of the second vibration arm is hinged to the upper part of the middle end of the second T-shaped vibration frame 6. Meanwhile, the connecting beam 9 is parallel to the upper surface of the base 1. The driving end of the driver 8 is connected to the middle part of the connecting beam 9 to drive the connecting beam 9 to vibrate up and down.

[0028] It should be noted that, in this embodiment, one end of the first leaf spring 4 is fixedly connected to the lower part of the first fixing frame 3, and the other end is fixedly connected to the first positioning seat 2. Simultaneously, one end of the first leaf spring 4 is fixedly connected to the lower part of the first fixing frame 3, and the other end is fixedly connected to the first positioning seat 2.

[0029] In addition, a connecting lug 10 is fixedly installed on the middle part of the connecting beam 9, and the driver 8 is located directly below the connecting lug 10. The driving end of the driver 8 is hinged to the connecting lug 10 to drive the connecting beam 9 to vibrate up and down.

[0030] It should be noted that in this embodiment, the driver 8 is fixedly installed on the base 1 and can be driven by a hydraulic servo cylinder.

[0031] It should be noted that in this embodiment, the two first leaf springs 4 are symmetrically arranged with respect to the middle end of the first T-shaped vibration frame 5, and the two second leaf springs are symmetrically arranged with respect to the middle end of the second T-shaped vibration frame 6.

[0033] After the crystallizer is placed on the first T-shaped vibrating frame 5 and the second T-shaped vibrating frame 6, they are fixed to the corresponding first T-shaped vibrating frame 5 and second T-shaped vibrating frame 6 respectively by positioning pins; when the hydraulic servo cylinder is activated, the power output end of the hydraulic servo cylinder vibrates up and down, thereby driving the first vibrating arm 7 to vibrate up and down around the hinge point on the first fixed frame 3, and the second vibrating arm to vibrate up and down around the hinge point on the second fixed frame, which in turn drives the first T-shaped vibrating frame 5 to vibrate up and down at the hinge point with the first vibrating arm 7, and drives the second T-shaped vibrating frame 6 to vibrate up and down at the hinge point with the second vibrating arm; and, due to the two lower first leaf springs 4 Both ends of the two second leaf springs are fixed, and the hinge point between the middle of the first leaf spring 4 and the first T-shaped vibration frame 5 vibrates up and down with the first T-shaped vibration frame 5. The hinge point between the middle of the second leaf spring and the second T-shaped vibration frame 6 vibrates up and down with the second T-shaped vibration frame 6. Therefore, the first leaf spring 4 can effectively buffer the up and down vibration of the first T-shaped vibration frame 5, and the second leaf spring can effectively buffer the up and down vibration of the second T-shaped vibration frame 6. It can also prevent them from getting stuck, reduce the load of the first T-shaped vibration frame 5 and the second T-shaped vibration frame 6 on the vibration device system itself, and prevent the lateral displacement of each moving part during vibration.

[0034] In summary, the vibration mechanism for crystallizers proposed in this application solves the problems of complex structure, heavy weight, large footprint, and inconvenient replacement associated with traditional leaf spring crystallizer vibration devices. It optimizes the structure of traditional leaf spring crystallizer vibration devices, making the overall structure simpler, reducing weight, saving manufacturing costs, and making hoisting and replacement more convenient, thus broadening its applicability. Furthermore, the device is easy to disassemble, simple to maintain and replace, and has low manufacturing costs. It uses hydraulic transmission, and the cost of easily damaged parts is low, making it economical and practical.
