This National model 7-4 forging machine is designed for high-capacity industrial forging applications, capable of delivering a forging force of 1500 tons. It features four forming dies, enabling versatile production with a rate ranging from 45 to 70 parts per minute. The machine accommodates parts with a maximum weight of 14.3 lbs and supports a maximum cutoff diameter of 76 mm and cutoff length of 155 mm. The maximum die and punch kickouts are 155 mm and 70 mm respectively, allowing for efficient part ejection.
The forging machine supports part outer diameters up to 165 mm. Die diameters are specified as 228 mm for the first die and 298 mm for the second, third, and fourth dies. Punch diameters for all four stages measure 222 mm. The main motor has a power rating of 370 kW, providing robust energy for heavy forging tasks. The machine's net weight is approximately 495,000 lbs, indicating a substantial and stable industrial unit.
Equipped with a fully adjustable four-feed roll box with feed roll reversing capabilities, it offers precise control over material feeding. Pneumatically controlled feed roll gripping pressure and infinitely variable stock gauge adjustments with length readout enhance operational accuracy. The machine includes a water-cooled quill die, punches, feed rolls, and feed roller shaft.
Additional features include individually adjustable die kickouts, overload relief on each die kickout lever, individual die caps, adjustable punch holders, and punch shut height adjustments. A rapid kickout sleeve adjustor with hydraulic locknuts and a fully timed transfer drive with straight-line vertical opening and closing ensure smooth operation. The setup is supported by a transfer setup fixture and a recirculating oil lubrication system for maintenance efficiency.
The machine is installed inside an industrial building featuring overhead lighting and ventilation. It includes yellow safety railings and stairs leading to an elevated platform with multiple control panels and mechanical components. The floor shows signs of heavy use, consistent with industrial operation. The machine is currently under power but not in production.
