1000 Ton / 10000 kN
Oversized Powertrain Fine Blanking Press
The HF-1000 handles the powertrain components that push smaller presses past their limits — heavy truck differential side gears, large-diameter transmission gears, differential carriers and torque-converter housings where blank diameters exceed 250 mm and material thickness reaches 22 mm. A 1000-ton triple-action hydraulic press with a 1100×1100 mm working table and 600 mm ring gear platen, it delivers the force density and platen area that oversized powertrain dies demand.
Typical applications: Heavy truck differential side gears, transmission gear clusters, differential carriers, large industrial sprockets, railway braking components
Consider a heavy truck differential side gear: 22 mm thick 20MnCr5 carburizing steel, 280 mm blank diameter, with a gear tooth profile that requires 100% shear edge across the full involute for noiseless meshing at operating load. On a conventional press, the 280 mm blank diameter exceeds the platen diameter, producing uneven V-ring impingement toward the outer edge — the V-ring loses contact, the material tears through rather than shears, and the gear tooth profile shows die-roll exceeding 25% of material thickness. The HF-1000's 600 mm ring gear platen fully covers the 280 mm blank, and the 2500 kN counter-pressure clamps the full cross-section flat, producing a gear tooth with die-roll below 10% and a shear edge that meets NVH (noise, vibration, harshness) specifications without downstream gear grinding.
The triple-force architecture is what makes oversized powertrain fine blanking possible at this scale. At 10000 kN of blanking force, the 200 kW hydraulic system with accumulator assistance maintains the controlled blanking speed (5-35 mm/s) that prevents adiabatic heat buildup in the shear zone — a critical factor on thick carburizing steel where excessive heat softens the die-roll zone and destroys the work-hardened edge structure. Each force system — main ram, V-ring impingement, counter-pressure — runs on an independent hydraulic circuit, enabling full programmability of the force profile through the CNC controller. The press ramps V-ring force to maximum before blanking begins, holds counter-pressure constant through the shear, and triggers ejection at a programmable point in the return stroke.
Each HF-1000 undergoes full-tonnage blanking trials during factory acceptance testing — not just hydraulic pressure verification, but actual part production on customer-specified material. Documented results cover tonnage curve, ram parallelism across the die area, V-ring engagement uniformity, and edge-quality measurement on the produced sample. For defense and aerospace applications, the press can be configured with enhanced process monitoring, full-force sensor feedback, and documented traceability of all critical components — meeting the documentation and quality requirements of highly regulated industries.
