Description

Technical Field

[0001] The utility model relates to the technical field of ingot starters, in particular to an ingot starter of a crystallizer. Background Art

[0002] The dummy bar is one of the important devices for continuous steel casting and ironmaking. The dummy bar consists of a dummy head, a transition piece and a rod body. Before pouring, the dummy head and part of the transition piece enter the crystallizer to form the movable "inner bottom" of the crystallizer. After pouring begins, the molten steel solidifies and condenses with the dummy head. The dummy bar is pulled by the straightening machine to continuously pull the billet out of the crystallizer until the dummy head is cut off and separated from the billet by the flame cutting machine behind the straightening machine and enters the dummy bar storage device;

[0003] The published document CN202321811583.7 (ingot head flipping device) records that by connecting the first connecting rod transmission assembly and the second connecting rod transmission assembly to the output end of the clamping drive assembly and symmetrically arranging them in opposite directions, the clamping drive assembly synchronously drives the first connecting rod transmission assembly and the second connecting rod transmission assembly to move in opposite directions, thereby driving the first clamp and the second clamp to move closer to or away from each other, thereby realizing the action of synchronously clamping or releasing the ingot head, which is easy to operate and has high clamping efficiency; however, the clamp used for clamping and flipping the ingot head in the published document is located at the front of the entire device, and the ingot head is heavy. When the clamp clamps and flips the ingot head, it is easy to cause the center of gravity of the entire device to deviate, which may cause the device to tip over. Therefore, we have introduced a new crystallizer ingot head. Utility Model Content

The left side of the front end, the right side of the front end, the left side of the rear end and the right side of the rear end of the bottom plate 11 are fixedly connected with stable support feet 13. The two first telescopic cylinders 2 are respectively fixedly connected with the two mounting grooves 14, and the ingot head body 6 is located inside the flip placement groove 12. By arranging stable support feet 13 at the four corners of the base 1 used for supporting the device, the ground contact area of ​​the base 1 can be increased to a certain extent, so that the stability of the device during use is higher.

[0026] In this embodiment, the flipping mechanism 5 includes a servo motor 51, and the output end of the servo motor 51 is fixedly connected to a fixing plate 52.
