Bed/bolster plate is the rigid foundation component of a precision hydraulic stamping press that supports the die and workpiece during metal forming operations.
The bed/bolster plate is a critical structural component in precision hydraulic stamping presses, serving as the stationary base that provides a flat, rigid, and vibration-dampening surface for mounting the lower die. It absorbs and distributes the immense forces generated during stamping operations (typically ranging from 100 to 10,000 tons), ensuring dimensional accuracy and stability. This component maintains precise parallelism with the ram/slide assembly, prevents deflection under load, and often incorporates T-slots, bolt patterns, or standardized mounting features for die installation. Its design directly influences press rigidity, part quality, and tooling longevity.

Technically, the 'bed' refers to the main structural frame of the press, while the 'bolster plate' is the removable or integrated mounting surface attached to the bed. In practice, 'bed/bolster plate' describes the combined functional unit that supports dies.
Flatness should be checked annually under normal use, or every 500,000 cycles in high-production environments. Immediate inspection is required after any crash or overload event.
Yes, worn or damaged surfaces can be machined and re-hardened, but material removal must not exceed 10% of original thickness. Severe damage typically requires replacement.
