Description

Technical Field

[0001] The utility model relates to the field of bending machines, in particular to an anti-warping mechanism of a bending machine. Background Art

[0002] A press brake is an important mechanical tool used for sheet metal processing. It forms the sheet metal into the desired contour by applying force to the workpiece. This machine is mainly used for bending and forming metal sheets. It can handle a variety of sizes and shapes from small parts to large workpieces, thereby bending the sheet metal to the desired angle shape according to the needs of the user.
