[0002] A continuous casting machine is a device used in steel production, which is mainly used to continuously cast liquid molten steel into solid billets. The continuous casting machine pours high-temperature molten steel from a ladle into a tundish and then injects it into a crystallizer through an immersed nozzle; the molten steel cools in the crystallizer and forms a billet shell, which is then pulled out through a billet drawing machine and further cooled and solidified in a secondary cooling zone to form a continuous cast billet. During the processing, hydraulic shears are required to cut the billets. The existing hydraulic shears for continuous casting machines can basically meet daily use needs. However, if the billets are not fixed during the shearing process of the hydraulic shears, the shearing accuracy is easily affected by offset, and the clamping position of the mechanism needs to be adjusted according to different billet sizes, which affects the practicality of the hydraulic shears. At the same time, most of the existing hydraulic shears are fixed on the continuous casting machine. In order to meet different cutting needs, they can only be arranged in a single manner, which affects the processing efficiency of the continuous casting machine. Therefore, it is very necessary to design a hydraulic shear for continuous casting machine billets. Summary of the Invention
