Working principle of hydraulic deflection compensation mechanism

During the bending process, the slider and the workpiece undergo a certain amount of deformation due to stress, resulting in inconsistent angles of the bent workpiece, especially for hot-rolled plates such as stainless steel, which have large rebound forces and errors. This series of bending machines adopts a worktable hydraulic automatic deflection compensation mechanism, which is composed of a set of oil cylinders installed in the lower worktable. The position and size of each compensation oil cylinder are designed based on the deflection compensation curve of the slider and worktable finite element analysis. Hydraulic compensation is achieved through the relative displacement between the front, middle, and rear three vertical plates to compensate for the protrusion of the neutral plate. Its principle is to achieve protrusion through the elastic deformation of the steel plate itself, so its compensation amount can be adjusted within the elastic range of the worktable.
