Technical Field

[0001] The utility model relates to the technical field of steel correction, in particular to a steel hydraulic correction device. Background Art

[0002] Steel is indispensable in the production and processing of ships. Since steel may be deformed due to cutting force or extrusion force during cutting or storage, the steel must be shaped and corrected before it is applied to ships to reduce its deformation. In the prior art, the utility model patent with patent application number 202021298857.3 discloses a hydraulic straightening device for fine steel, which is mainly composed of a support plate and a pressure plate above the support plate. When shaping the steel, the steel is first placed on the support plate, and then the pressure plate is lowered by a hydraulic mechanism until the pressure plate contacts the steel, so that the pressure plate presses down on the steel, and the steel is corrected under the squeezing of the pressure plate and the support plate; the inventor believes that there are the following problems during use, because the steel will not only deform in the up and down directions, but also in the front and back directions, and the device in the above-mentioned prior art can only shape the steel in the up and down directions.
