Description

Technical Field

[0001] The utility model belongs to the field of hydraulic shears for steel billets, in particular to a hydraulic shear for steel billets of a continuous casting machine. Background Art

[0002] A steel billet is a product obtained by casting molten steel produced in a steelmaking furnace. It is a semi-finished product for producing steel. Since the steel billet is a semi-finished product of steel, it needs to be sheared to a specified length before subsequent processing. However, the steel billet shearing devices currently on the market are inconvenient to adjust the position of the shearing point of the steel billet during use. The position of the steel billet needs to be continuously adjusted during quantitative shearing of the steel billet. The inconvenience in adjustment due to the heavy weight of the steel billet greatly reduces the efficiency of the steel billet cutting and cannot meet people's use requirements. In addition, if the steel billet is not fixed during shearing, it may slip during the shearing process, resulting in substandard steel billets after shearing, resulting in waste of raw materials and losses to producers.

[0003] In contrast, a Chinese patent with announcement number CN 219944750 U discloses a large-angle steel billet hydraulic shear, including a shearing structure and an adjustment structure, wherein the shearing structure includes a shell, a shearing assembly and a through hole, wherein the shearing assembly is arranged in the shell, and the through holes are opened on both sides of the shell, and the adjustment structure includes a sliding assembly, two clamping plates and a first sliding column, wherein the sliding assembly is arranged in the shell, and the two clamping plates are connected to the sliding assembly, and the first sliding column is arranged in the shell, and the two clamping plates are both slidably connected to the first sliding column.

[0004] However, the above patented adjustment mechanism requires a separate motor to control the clamping mechanism, which has a relatively complex structure and is difficult to ensure the continuity of the clamping device working with the shearing device. Therefore, a new device must be designed. Utility Model Content
