Bending process is one of the most significant fields of application of sheet metal die. In bending process, it is quite vital that the product should have the desired angle. Furthermore, in order to obtain the desired angle in the bent parts, spring-go and spring-back amounts must be known. In this study, 30o, 60o and 90o bending processes were applied to S235JR (1.0038) sheet metal having 3, ...

sheet metal components design and manufacture need a great deal of experience and know-how. strip layout design is usually done with trial and error until best design for strip layout is finally achieved. knowledge for the system is formulated from plasticity theories, experimental results, and the empirical knowledge of field experts. in this paper, an algorithm which can automatically design ...

The V-die bending force is an important parameter in respect of press machine capacity selection, but it has not been the focus previous research. Furthermore, while various modified formulas proposed research were calculated using theory, they are insufficient for predicting actual force. Based on mechanism, a new formula this study, which generated only allowance zone also legs next to zone. ...

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 ...

A 3D mathematical model of orthodontic archwire with rectangular curve is established. Simplified 3D solid model of orthodontic archwire bending robot, which is consistent of bending die, support structure and archwire are established by Creo software, then the simplified model of bending die is put into ANSYS Workbench. Material parameters the contact condition and boundary conditions are set ...

This paper combines adaptive network fuzzy inference system (ANFIS) and finite element method (FEM) to study the die shape optimal design in sheet metal bending process. At first, the explicit dynamic FEM is used to simulate the sheet metal bending process. After the bending process, the springback is analyzed by using the implicit static FEM to establish the basic database for ANFIS. Then, the...

Effect of retained austenite characteristics on V-bending in ultrahigh-strength TRIP-aided steel sheets with bainitic ferrite matrix (TBF steel) was investigated for automotive applications. tests were performed a servohydraulic testing machine at processing speed 1 mm/min using 88-degree V-punch (2.0 mm punch radius), V-die (12 die gap, 0.8 shoulder and rectangular specimen (50 length, 5 width...

one of the most prominent industries is bending, while using rotary draw bending method is known to be the most conventional approach for thin wall tube bending. pressure die is one effective tool which boosts the tube during the process and eventually improves the bending quality. other effective parameters are mandrel and the amount of clearance between tube and mandrel. in the present study,...
