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.
