Wuxi Wonderly Industry Equipment Co., Ltd. presents the WDL-25 Fully Automatic Suspension Hot Spring Rolling Machine, a state-of-the-art, integrated production line designed for the high-speed and precise manufacturing of hot coil suspension springs. This advanced system handles a material diameter range of 10 to 25mm and is capable of producing cylindrical springs, single conical springs, and double conical springs with exceptional consistency and automation. Engineered for unmanned operation, the WDL-25 combines an automatic spring coiling machine, a 6-axis industrial robot, and a sophisticated central control system to deliver a complete, turnkey solution for automotive and industrial spring manufacturers.
The core of the system is the high-performance automatic spring coiling machine. It features a powerful 22kW main motor driving the rolling spindle, while precision is ensured by dedicated servo motors for pitch control (11kW) and outer diameter control (0.4kW). The machine incorporates functions like automatic feeding, mandrel clamping, and a tilting body for complex geometries. Heated wire rod (at 920°C-950°C) is precisely fed, positioned, and rolled into final spring shape with minimal deflection (below 3mm/M).
Automation is completed by a Yaskawa GP180 6-axis articulated robot. With a payload of 180kg and repeatability of ±0.05mm, this robust robot is equipped with a high-temperature fixture to automatically and reliably transfer the hot-coiled springs to the next processing stage. The entire production flow is orchestrated by an intelligent centralized control system featuring a Delta touchscreen. This system allows for easy parameter setting, remote monitoring via 4G connectivity, production data logging, and comprehensive alarm management, enabling seamless integration into smart factory environments.
