In the era of intelligent and precision-driven automotive production, servo motor-driven electric screw presses have emerged as indispensable core equipment. By integrating advanced servo control technology with mechanical transmission, these presses have revolutionized key processes such as component assembly and precision forming in automotive manufacturing. They not only meet the stringent requirements for quality and efficiency but also align with the industry’s trends toward energy conservation, environmental protection, and flexible production.

Core Working Principle and Technical Advantages

The servo motor-driven electric screw press features a servo motor as its power source. Through belt transmission, the motor’s rotational force is transferred to the flywheel, and the flywheel then converts this rotational motion into vertical linear motion of the slider to complete pressing, assembly, or forming tasks. Its closed-loop control system enables real-time monitoring and adjustment of pressure, position, and speed, creating technical advantages that traditional hydraulic or pneumatic presses cannot match.

Micron-level Precision Control: It achieves a positioning accuracy of ±0.01mm regardless of load or speed, with pressure precision reaching ±0.25%FS . This ultra-high precision ensures the accurate assembly of critical automotive components, avoiding damage caused by over-pressure or under-pressure.

Flexible Production Adaptability: It can store and call hundreds of customized pressing programs, allowing quick switching between different product specifications without the need for additional hard stops on tooling . This flexibility perfectly suits the modern automotive industry’s trend of multi-variety and small-batch production, significantly reducing mold debugging time .

Energy Conservation and Low Maintenance: Compared with traditional hydraulic presses, it saves up to 80% energy, with standby power consumption as low as 50W . Its simple servo electric system eliminates hydraulic oil pollution risks and reduces long-term operational and maintenance costs .

Key Applications in Automotive Production

The servo motor-driven electric screw press plays a pivotal role in various critical processes of automotive manufacturing, covering core components such as engines, transmissions, and body structures.

Engine Assembly: It is widely used for pressing cylinder heads, cylinder liners, piston rings, and valve seats . The precise pressure control ensures tight fitting of these components, directly affecting the engine’s power output, fuel efficiency, and service life.

Transmission Manufacturing: For high-precision components like gears and bearings, the press supports multi-stage composite pressing modes, meeting strict requirements for assembly consistency and compatibility .

New Energy Vehicle Production: It adapts to the forming and assembly needs of new energy vehicle components such as battery casings. Its flexible processing capabilities cater to the rapid iteration of new energy vehicle models .

Body Structure Processing: In body stamping, it achieves one-time forming of complex parts through dynamic pressure adjustment, reducing scrap rates and shortening production cycles .

Future Development Trends

As the automotive industry evolves toward electrification, intelligence, and lightweighting, servo motor-driven electric screw presses are moving toward deeper intelligence and integration. Future models will leverage AI algorithms for adaptive parameter optimization, predicting maintenance needs to minimize downtime . Modular design will be further promoted to support faster customization and integration into automated production lines . Additionally, energy recovery technology will be upgraded, with brake energy recycled and reused to achieve even higher energy efficiency .

In conclusion, servo motor-driven electric screw presses have become a cornerstone of modern automotive manufacturing, driving improvements in product quality, production efficiency, and sustainability. Their technical advantages and flexible application capabilities make them an essential choice for automotive manufacturers pursuing high-precision and intelligent production. As technology advances, these presses will continue to innovate, contributing significantly to the transformation and upgrading of the global automotive industry.
