A bending machine is a forming machine tool (DIN 8586). Its purpose is to assemble a bend on a workpiece. A bend is manufactured by using a bending tool during a linear or rotating move. The detailed classification can be done with the help of the kinematics. [1] Universal bending machine for flat material
Roll bender machine. A roll bender is a mechanical jig having three rollers used to bend a metal bar into a circular arc. The rollers freely rotate about three parallel axes, which are arranged with uniform horizontal spacing.
Various applications are used to produce bar bending schedules which can be directly fed into CNC machines that cuts and bends the rebar to the desired shapes. The fabrication of the bars is scheduled and the placing/fixing sequence indicated, adding the elements required to support those bars during construction.
Values for the flexural strength measured with four-point bending will be significantly lower than with three-point bending., [7] Compared with three-point bending test, this method is more suitable for strength evaluation of butt joint specimens. The advantage of four-point bending test is that a larger portion of the specimen between two ...
Bending A chimney starter, a sample product of bending. Bending is a manufacturing process that produces a V-shape, U-shape, or channel shape along a straight axis in ductile materials, most commonly sheet metal. [1] Commonly used equipment include box and pan brakes, brake presses, and other specialized machine presses.
Within the trades rebar is known by a shorthand utilizing the bar diameter as descriptor, such as "four-bar" for bar that is four-eighths (or one-half) of an inch. The cross-sectional area of a bar, as given by πr², works out to (bar size/9.027)², which is approximated as (bar size/9)² square inches. For example, the area of #8 bar is (8/9 ...
Its popularity led bar bending to be continued for six more years until 1983. [8] One of the most notorious moments of strongman occurred during 1981 World's Strongest Man competition when Bill Kazmaier and Geoff Capes injured themselves [9] while attempting to bend the final iron bar of the event to declare the event winner.

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.
