A bending machine is a mechanical device specialized in the bending of metal materials. It realizes the bending deformation of metal materials by applying force and controlling the movement of the table and other components.

There are many types and functions of bending machines, which can be used as both presses and bending machines. Some bending machines can work directly on sheet metal without the need for a clamping tool, while others require a clamping tool to assist in bending. The sheet metal is held in place by a clamping device and remains in place throughout the process. Bending machines use bending tools to shape the sheet metal and create the desired contour. The body and tools of a bending machine must be made of special materials to ensure that they can withstand the stresses of the process without being damaged.

A bending machine works by using force to compress a sheet of metal between two opposing (usually flat) dies. The sheet is usually fed into the machine and then bent to a desired angle. The degree of bending is usually determined by the size and shape of the dies and the pressure applied by the machine.

When metal is placed between two dies, the top die moves downward, pressing the metal against the bottom die. The pressure applied by the bending machine bends the metal into the desired shape and angle. The design of the machine allows precise control of the angle, depth and width of the bend. It drives punches and dies through different drive sources to bend repeatable metal sheets and form profiles. Different thicknesses and lengths of material require different bending forces.
