Lingxie Intelligent Riveting Equipment Empowers the New Energy Vehicle Industry

New energy vehicles are undergoing a comprehensive upgrade featuring lightweight design, high safety, intelligence and high efficiency. Steel-aluminum hybrid bodies, integrated die-casting technology, power battery packs, chassis structural parts, motor and electronic control components impose far stricter requirements on connection processes than traditional fuel vehicles. Traditional welding suffers from thermal deformation, brittleness of dissimilar materials and damage to battery cells, while manual riveting delivers low precision and poor consistency, failing to meet mass production and safety standards.

As a professional manufacturer deeply engaged in the riveting industry for many years, Changzhou Lingxie Intelligent Equipment independently develops a full range of products including intelligent press riveting, radial riveting, servo press-fitting and automated riveting equipment. It effectively addresses technical challenges in the manufacturing of new energy vehicles, and fully empowers the lightweight transformation, safety upgrading and intelligent mass production of the new energy vehicle industry with domestic high-end intelligent riveting technology.

1. Industry Transformation: New Energy Vehicles Drive Comprehensive Innovation in Riveting Technology

There are essential differences between new energy vehicle manufacturing and traditional fuel vehicle manufacturing. Battery packs account for 30%–40% of the total vehicle weight, so vehicle lightweighting is essential to extend driving range. Hybrid application of steel, aluminum alloy, high-strength steel, copper-aluminum composite materials and composite materials has become standard configuration. Battery packs require IP67 high sealing performance, vibration resistance, high temperature resistance and freedom from high-temperature damage. Vehicle bodies and chassis demand ultra-high fatigue resistance, crash resistance and long service life. Meanwhile, automakers are in urgent need of flexible, automated and data-based production lines to support efficient mixed-line mass production of multiple vehicle models.
During dissimilar material connection, traditional welding easily generates brittle intermetallic compounds, resulting in greatly reduced joint strength, high rejection rate due to thermal deformation, and high temperature damage to battery separators and electronic control components. Conventional manual riveting features low precision, frequent false riveting and missing riveting, low efficiency and no data traceability, which cannot comply with ISO26262 functional safety and batch quality control requirements for new energy vehicles.
Cold-forming intelligent riveting has become the optimal core connection solution for new energy vehicle manufacturing, thanks to its advantages of zero high temperature, compatibility with dissimilar materials, high-precision mechanical interlocking, excellent sealing performance and full-process controllability.
Following industry trends and targeting exclusive process demands of new energy vehicles, Lingxie Intelligent has built a multi-dimensional intelligent riveting equipment system integrating standard machines, automated solutions and non-standard customization. It covers full scenarios including press riveting, radial riveting, servo precision press-fitting, automatic feeding riveting and robot integrated riveting.
