Review of Spring Back for Rod Bending Machine

V. C. Patel | Kaushal Prajapati | Rathwa Harish | Rathava Falgun | Tadvi Hardik

Abstract: The most sensitive feature of the sheet metal forming is the elastic recovery during unloading, called spring back. Sheet metal forming is one of the prominent methods to convert blank sheet material into a product. In sheet metal forming, proper allowance of its tools must be given to the elastic recovery, due to the nature of elastic property which is called spring back. So theoretically and practically experiment and analysis of bending material, the bending process depend on material mechanical properties like hardness, strength, flexibility, ductility, brittleness etc. and find proper angle maximum bending and material recover to require angle. Like we aspect 45 degree bending angle so, we will bend max of (45 degree LIKE 50 degree) so, 5 degree recover and we get 45 degree angle. The angle made on die (suppose we get 45 degree and we produce die valley angle is 50 degree).

Keywords: Elastic deformation spring back, Bar or rod of different material, plate, angle measurement tools angometer
