Clamping dies for press brakes: quick‑change & high precision

System overview: how clamping dies deliver repeatability

Clamping dies lock the die in a repeatable seat for fast tool changes. Performance depends on bed‑ram parallelism, seat stiffness and the quality of guides/stops. Mechanisms can be mechanical, pneumatic or hydraulic—all require clean, flat interfaces.

Target: L–C–R angle variation ≤ ±0.5° and level Δ ≤ 0.05–0.10 mm after changeover.

Installation, alignment and post‑change verification

1. Degrease seat and bearing faces; correct high spots with a straightedge.
2. Present clamping die and tool; snug in a cross pattern.
3. Sweep every 200–300 mm with a dial indicator: Δ ≤ 0.05–0.10 mm.
4. Center punch‑V with gauges/straightedge; shim only if required.
5. Record torque/crowning and L–C–R angles on a witness coupon.

Standardize the procedure per machine/shift to reduce variability.
