Publication number: 20150198351Abstract: A multi-shaft bending machine for bending two rectangular duct bodies, such as trunk lead hanger arms for a vehicle at the same time. Barrier pieces are installed in a mandrel including three rollers and a rectangular duct body support that forms a bending machine so that two rectangular duct bodies are not mutually influenced when a bending work is performed on the two rectangular duct bodies. A rotation plate is rotated by a plurality of shafts connected to a driving motor through clutch gears. Accordingly, a difference between strain rates on the outer and inner sides of a bending part can be reduced, lubricating oil injected into the oil grooves of the rollers performs a lubrication action, and the structure of a bending machine can become simple because the rotation plate is rotated by the plurality of shafts connected to the driving motor through the clutch gears.Type: ApplicationFiled: January 16, 2014Publication date: July 16, 2015Applicant: BEIJING JINGUMCHANG AUTOMOBILE HITECH CO., LTD.Inventors: Cheol HEO, Se Gil SHIN
