Based on the above and conbination with a practical example, this paper presents a calculative method for flanging force.

Design of compound punching die for shaft cover with blanking-drawing-piercing-flanging-trimming;

Finite element simulation of titanium alloy sheet flanging process;

Analysis and Application of Inverse Flanging Line Based on Sheet Forming simulation;

Taking the front floor as an example, mainly introduced the hoisting wedge driver installed in active pressing material core and making use of reverse wedge driver to form the up flanging structure.

The forming conditions of flanging-drawing workpiece are more difficult to predict than single drawing one.

Accroding to the flanging die for cylindrical part, die using sliding punch to flang is designed.

The forming technology of rear shock absorber cap is analyzed,and its drawing die,flanging die and spinning die structure are also introduced.

Stamping tube preform parts used flanging die is not only improve productivity,but also reduce the cost of die design and manufacture,various tube preform part could be made through change part structure of flanging die.
