WebForging force calculation As shown in Figs. 2-4, simulation results of forging force during extrusion, pre-forging and final forging stages are figured. The abscissa represents the stroke of the ram, thereto, right end indicates the bottom position of the ram, ... Forging force (kN) Energy (kJ) Valid stroke (mm) Extrusion stage 61000 788 120 ... WebDrawing ratio (m) = 0.75 → K = 0.90. 0.80 → K = 0.62. 0.82 → K = 0.52. 0.85 → K = 0.42. 0.90 → K = 0.20. When the drawing ratio is the same in both initial drawing and redrawing, the K value will be larger in redrawing. This is due to the effect of work hardening of the material. The drawing force obtained by calculation appears ...

WebFor piercing a hole: Tonnage = d * t * 80 Equation 1. In this equation d is the punch diameter in inches, t is the material thickness in inches, and it gives the tonnage in tons. This was a very simple and effective way to estimate the tonnage of all the holes pierced. Let us look at how this rule of thumb was derived. WebStep i) To decide the dimensions to be used in the calculations: Data: h=25mm 2a=200mm w=200mm=constant Step ii) To determine the condition of friction between die and work … WebMar 1, 2024 · The punching force (F) is a function of the shear strength (S), workpiece thickness (t), and the perimeter of the hole (P). You can calculate the punching force using the formula: F = P \times S \times t F = P × S × t If the shear strength is unknown, you can estimate that using the material's tensile strength (T). hubsan h107c+02 lipo 1s 3.7v 520mah battery
