Anyang Forging Press Since 1956
China National Forging Hammer Standard Drafter
The direct-drive electric screw press (servo direct-drive screw press) belongs to the third generation of precision CNC forging equipment. It eliminates the traditional intermediate transmission mechanisms such as friction discs, pulleys, and reduction gears, and uses a low-speed, high-torque permanent magnet synchronous servo motor to directly drive the flywheel-screw assembly. This directly transmits the motor torque to the screw, converting rotary motion into linear impact motion of the slide block. Forging is achieved by relying on the energy stored in the flywheel.
Working principle of the Direct Drive Electric Screw Press (J58ZK)
A servo direct-drive motor directly drives the flywheel to rotate, which in turn drives the screw to rotate. The screw-nut pair converts the rotational motion into the downward linear motion of the slider. The flywheel stores kinetic energy to complete the impact shaping. After the impact is completed, the motor reverses to drive the slider back. The flywheel speed and slider position are collected in real time by an encoder, and the PLC controls the impact energy, stroke, and number of impacts in a closed loop to achieve digital precision impact. A spring braking mechanism is provided to lock the flywheel when the machine stops, ensuring safety.
Direct Drive Electric Screw Press (J58ZK) Core Advantages:
Precise and Controllable Impact Energy:
Full closed-loop servo control allows for continuous adjustment of impact energy from 0-100%, ensuring high consistency in energy output per impact. This results in stable forging dimensional accuracy, reduced scrap rates, and suitability for precision die forging and stamping processes.
High Transmission Efficiency and Energy Saving:
Eliminating wear-prone components like gears and belts achieves a transmission efficiency of up to 90%, saving 10-25% energy compared to ordinary electric screw presses. Energy is output on demand, eliminating idling losses and reducing production electricity costs.
Low Failure Rate and Simple Maintenance:
Significantly shortened transmission chain reduces the number of easily damaged transmission parts. Eliminates issues like friction disc wear and belt aging replacement. Forced circulation lubrication and cooling for the screw and nut reduces thread burn-in. Daily maintenance workload is significantly reduced, extending equipment lifespan. Excellent process performance (stable): Strong resistance to eccentric loads; short impact contact time, low mold heating and impact stress, extending mold life by 20-30%; capable of single and multiple impacts, adaptable to various forging processes.
Production environment friendly (quiet):
Frictionless transmission noise during operation, low overall machine noise, retaining only the sound of forging and mold closing, improving the workshop working environment.
Intelligent, compatible with automated production lines: Touchscreen human-machine interface, digital parameter setting, fault self-diagnosis; supports loading and unloading linkage with industrial robots, compatible with fully automated forging production lines, supporting 24-hour continuous production .
