Sheet Bending Machine

a machine for bending and straightening metal sheets and strips. Sheet-bending machines with a rotary bending beam are designed for cold linear bending to produce parts of various shapes, as well as pipes on mandrels; to form flanges and closed contours; and for straightening sheet material.A brake is a metalworking machine that allows the bending of sheet metal. A cornice brake only allows for simple bends and creases, while a box-and-pan brake also allows one to form box and pan shapes. It is also known as a bending machine or bending brake or in Britain as a sheet metal folder or just a folder.The bar bending machine consists of an electric motor, a coupling, a circular plate, a worm gear drive, and an extended shaft. An electric motor transmits power to a gearbox, which decreases speed and increases torque. A circular plate bends the bar using this gearbox.Most tubes, though, are bent one of four ways: ram-type bending, roll bending, compression bending, or rotary draw bending.
