During the precision alignment phase of high-speed stamping presses, this adjustable clamping segment secures the blank holder ring to the press ram with repeatable accuracy. In progressive-die setups, the segment’s wedge-shaped profile slides into a matching slot on the ram, allowing operators to fine-tune the blank holder pressure without disassembling the tool stack. This adjustment is critical when running materials of varying thickness or when switching between mild steel and aluminum coils, as it prevents wrinkling on the draw radius while avoiding excessive thinning at the punch edge. On automated transfer lines, the same segment enables quick die changes by letting maintenance crews pre-set the blank holder force offline, then lock the segment in place with a single bolt during tool swap. The design also compensates for thermal expansion during long production runs, maintaining consistent flange control across the entire stroke.
