The Design of Small Three Roller Bending Machine
Abstract: As a special one, the bending machine occupies an important position in the basic industral processing . It is widely used in boiler, shipbuilding, oil, wood, metal structures and other machinery manufacturing industries.This article is a design of the symmetrical three rollers bending machine.The article expresses the structure and the force analysis of the bending machine. In this very strcture , the  upper roller will press downward to offer the stress , and two lower rollers will whirling to provide the torque.Meanwhile , the power has been choosed as the YZ160L-6 belong YZ series electric motor whose working efficiency will definitely surpass the Y electric motor , and it is generally utilized in the condition which contains the slight shock .Besides, the speed reducer which is involved in the whole design utilized the structure of the three expansion.
