Review on Design and Analysis of Portable Rolling and Bending Machine

In this paper we are discussing about the difference in roll pressure distribution was assumed linear. Using this model rolling parameters such rolling force, torque and the developed curvature were easily calculated. Bending moment can be applied in suitable direction. In addition, employing a bending moment at entry of the roll gap in a symmetrical rolling process causes pressure difference on the rolls and warping at the outlet, as happens in an asymmetrical rolling process. In Portable bending machine is device which gives the less efforts of man and gives the required work properly of the construction and other metal fabricated areas. The base of this machine is mounted on the large C-clamp; This C-clamp is attaches to workbench surfaces up to 2" thick; a rubber base pad protects the mounting surface. The orientation of the jaws is adjusted by a single clamping bar mechanism to provide quick repositioning of the work. Instrument makers will find many uses for this versatile vice. This machine work smoothly and gives proper dimension of the required jobs. A beam deforms and stresses develop inside it when a transverse load is applied on it. In the quasistatic case, the amount of bending deflection and the stresses that develop are assumed not to change over time. Its one end having metal bending device & another end having Bench vice which is rotating about its Axis and hold work piece at any angle? The base plate is rotating of an angle 360 about its central Axis. This machine is used for heavy duty metals which are used in construction areas and multiple operations are performing on it. It is light in weight and portable attach to any work table in Industries, Workshop and Construction areas.
