Stress State and Spring Back in V-bending Operations
Bending is one of the most common metal forming technology and it can be applied not only in sheet metal forming but also in forming of wires, rods, strips, pipes and bars. However, in car production, ship building and home appliance manufacturing sheet metal bending is most widely employed. One of the most significant sheet metal bending operations is V – Die bending. This process consists of ...
متن کاملEffect of Spring-back in V-tool Bending of High-strength Steel Sheet Metal Plates
B. Grizelj, J. Cumin, Mechanical engineering Faculty in Slavonski Brod, Slavonski Brod, Croatia D. Grizelj, Siemens, Zagreb, Croatia. This paper deals with the eff ects of technological parameters used in the V-die bending process, on the obtained product properties and dimensions. By variation of the tool geometry, several cases of steel sheet bending process are observed through the FEM simul...
متن کاملNumerical Simulation and Neural Network Prediction the Cold Bending Spring back for Ship Hull Plate
The accurate prediction of the spring back has great significance to the cold bending of plates. Based on the analysis of the square non pressure head CNC bending machine forming principle, the finite element model of the cold forming of the hull plate surface was established using the ANSYS/LS-DYNA finite element software. And the spring back computing research was done on the thickness of 8 m...
متن کاملSpring-back behaviour of thin metal foils in free bending processes
Metal foils attract a large field of applications, e.g. in micro-technology they are being used for sensors, actors, micro-electro-mechanical systems and in medical devices. Conventional sheet metal forming processes are in principle applicable for metal foil forming. Reducing the sheet thickness to the order of micrometers, however, causes various scaling effects. Therefore, the know-how of co...
