YJ-320 Pushing the Limits of Cold Coiling - Emerging for EV Demand
Under the overarching trends of net-zero emissions and energy efficiency, Electric cars are gradually replacing gasoline-powered vehicles. While electric vehicles do away with components like engines and gearboxes, the batteries that power them are significantly heavier. A good load-bearing suspension system brings comfort and safety on the ride, and the suspension spring plays an important role in it.
The suspension spring primarily bears the vehicle's weight and provides flexibility to reduce the impact of vibrations and bumps, especially during sharp turns and on uneven road surfaces. A spring with a larger diameter and higher tensile strength provides better support for the additional load. However, manufacturing springs with larger diameters and higher tensile strengths poses significant challenges for spring manufacturers.
The YJ-320 spring machine emerged as a groundbreaking solution to this challenge. By further improving the cold coiling technology, it can manufacture suspension springs with diameters up to 22mm and tensile strengths up to 2,000 MPa. The mechanical design of the YJ-320 not only emphasizes strength but also integrates operability and safety. It is equipped with advanced Japanese Yaskawa servos and control system and in-built patented spring editing software to meet the future demands of the electric vehicle market.
The cold coiling process is more popular than the hot coiling process. Apart from the complex forming process and geometric limitations, the hot coiling process requires a lot of energy during spring production and is unfriendly for the working environment of the production line. The manufacturing process is not as eco-friendly as the cold rolling process.
SIMCO has always been a leading brand in large cold coiling spring machines. In the 2016 CASMI show in the USA, SIMCO was the first to showcase an EJ-250 coiling machine capable of producing springs with 20mm OT wire, demonstrating its technical prowess in suspension spring production.
