... in, the ring on the face of the die presses the lower layer of sheet material into the groove of the rivet shank, creating a positive lock (from closure) overlaid by nonpositive radial compressive stresses (view 4). The advantages of the punch riveting process are illustrated in Fig. 1 , which shows...

... through the punch: the ram force. Fine-blanking makes use of multiple forces created by a blanking plate, a vee-ring plate, a punch, and an ejector. The ejector maintains pressure against the punch throughout the upward stroke. The three main forces in a fine-blanking cycle—clamping vee-ring force...
