The proposed system is used for bending of flat bars of any length and any shape which requires bending at any location across the length of the flat bar. The proposed system facilitates the bending of flat bars at multiple required angles. Further, the system is operable by any person without any effort and does not require a skilled operator. The system mainly comprises a handle that needs to be operated in order to bend the flat bar wherein the flat bar is inserted into one of a plurality of grooves provided in the system. The groove is selected depending on the thickness of the flat bar. Said system is easy to install and can be easily dismantle at site as it only requires a table or bench for installation of the proposed system.

In one of the embodiments, the main shaft (104) and the handle (106) are configured to be connected to each other through welding, riveting, forging etc for the rigid connection. In a particular embodiment, length of the main shaft (104) and the handle (106) are configured to be 300 mm and 600 mm respectively wherein aforesaid lengths are subjected to vary depending on availability of space and thickness of the flat bar used for producing the hanger and seating. Further, a second guide plate (112) is configured to be fixedly connected to the main shaft (104) and the handle (106) as shown in figure. Said second guide plate (112) is configured to be of rectangular shape and is configured to be mounted on the main shaft (104) and perpendicular to the handle (106). In a particular embodiment, the second guide plate (112) is configured to be 80 mm long and 40 mm wide wherein said dimensions are subjected to vary. Further, the main shaft (104) is guided and supported through a plurality of hinges (108) wherein the main shaft (104) is free to rotate inside the hinges (108). The plurality of hinges (108) are configured to be hollow to provide free rotation of the main shaft (104). Further, the system comprises a first groove (116) and a second groove (118) of varying dimensions for accommodating the flat bars of different thicknesses.
