What is the function of the toothed ring clamp in the die?
So that the material in the shear zone is in the three direction compressive stress state; the material is pressed to avoid the bending and tensile deformation of the sheet metal; after the blanking is finished, the material is discharged again
A V - shaped rib around a certain distance from the workpiece contour. The action of the ring clamp is to prevent the metal sheet other than the shear zone and into the shear zone during the blanking,
The difference between the precision die and the ordinary die is that the V ring shaped clamp is adopted. The so-called ring gear plate is defined on the platen or die
