What is the pressing force in stamping parts processing?

The punching force in the processing of stamping parts includes punching force, discharge force, pushing force and ejecting force. Calculating the punching force is the basis for selecting the press. 1. The punching force in the processing of stamping parts Fu003dLtτ where F punching force (N); L punching part peripheral length (mm); t material thickness (mm); τ material shear strength (MPa). 2. Unloading force, pushing force and ejecting force in stamping parts processing 1) Unloading force in stamping parts processing is the force required to unload the material hooped on the punch, that is, F unloading u003d k unloading F2) The pushing force in stamping parts processing is the force required to push the blanking parts out of the die hole along the punching direction, that is, F push u003d nk push F3) The pushing force in stamping parts processing is the blanking The force required for the part to eject the die hole against the blanking direction, namely F top u003d k top F in the k unloading force coefficient; k pushing force coefficient; k top ejecting force coefficient; n die memory The number of pieces, nu003dh/t (h is the height of the straight wall of the die edge, t is the thickness of the workpiece); F punching force (N).
