The bed/die holder is the stationary base that supports and secures the lower die. It provides a rigid, flat surface against which the upper ram presses the workpiece, ensuring accurate and repeatable bends by absorbing bending forces and preventing die movement or deflection.
Common materials include cast iron and steel alloy. Material grades such as 45# or 42CrMo are referenced to Chinese standards GB/T 699 and GB/T 3077, with higher grades used for heavy-duty applications to enhance rigidity and wear resistance.
Key parameters include working width (1000–6000 mm), working length (2000–12000 mm), thickness (50–300 mm), flatness and parallelism tolerances (0.02–0.10 mm/m and 0.03–0.15 mm/m per ISO 1101), surface hardness (HRC 40–55 per ISO 18265), maximum load capacity (100–2000 kN/m), weight (500–15000 kg), and operating temperature (-10 to 60 °C). These must be matched to the press brake and application.
Always confirm model-specific values and standards with the legal manufacturer or supplier. The listed ranges are directory references and may vary. Check that the holder's working length matches your press brake bed, load capacity exceeds your bending force, and tolerances meet your accuracy requirements.
