Fully Automatic CNC Spring Coiling Machine

Fully Automatic CNC Spring Coiling Machine

The fully automatic CNC spring coiling machine is a modern core equipment for spring manufacturing that integrates CNC technology, multi-axis servo drive, and modular design. Its primary purpose is to achieve high-precision and high-efficiency automated production of springs. Compared to traditional spring coiling equipment, it completely eliminates reliance on manual intervention. Through digital control and coordinated operation of multiple mechanisms, it accurately completes the entire process from wire straightening to finished product cutting. It is widely suitable for the large-scale production of cold-coiled springs and has become an indispensable key piece of equipment in high-end manufacturing sectors such as automotive, industrial machinery, and medical devices, driving the spring manufacturing industry towards greater precision and intelligence.

Performance Characteristics: The fully automatic CNC spring coiling machine features a novel and aesthetically pleasing appearance with reliable, high-quality construction. Its feeding, cutting, and diameter reduction processes all employ a reducer ball screw structure. The couplings and motors utilize original Japanese servo motors, resulting in a more rational structural design that is easy to operate and maintain.

Working Principle: The working principle of the spring coiling machine involves the coordinated action of a series of mechanisms and components to process steel wire or spring steel strip into the desired spring shape. The CNC system acts as the "brain," typically integrating an industrial computer or PLC with a touchscreen, supporting a Chinese-language human-machine interface (HMI). Users can directly input parameters such as wire diameter, spring outer diameter, and number of coils for programming, and the system can store nearly a thousand spring programs, adapting to multi-variety production needs. Some high-end models are equipped with embedded systems to further enhance control precision.

Its main function is to produce springs, and its working principle involves the collaborative operation of several key mechanisms and components. These include the straightening mechanism, feeding mechanism, variable-diameter mechanism, pitch control mechanism, and cutting mechanism. Each mechanism has its specific function and role, working together to ensure precise spring manufacturing. The precision mechanical structure forms the core of the operation, consisting of the straightening mechanism, servo feed rollers, coiling mandrel, forming tools, and cutting mechanism. The straightening mechanism comprises two sets of rollers that eliminate the original bending deformation of the wire, ensuring feeding accuracy. The variable-diameter mechanism and pitch control mechanism precisely regulate the spring's outer diameter and pitch via cams or modular components, respectively.

Workflow: The workflow is highly automated: first, the wire is leveled by the straightening mechanism; then, it is precisely fed by the servo feed rollers, with the feed length accurately controlled by the rotation of the feed wheels. Under multi-axis coordinated control, the wire is fed to the coiling mandrel where forming tools shape it according to the set program, enabling complex processes like variable diameter and variable pitch. Finally, the cutting mechanism precisely severs the wire, completing the spring processing. Some high-end models also integrate features like wire break detection and program modification without stopping, further enhancing production continuity.

Development Trends: Fully automatic CNC spring coiling machines are evolving towards higher precision, greater integration, and increased intelligence. Key R&D focuses include optimizing precision control algorithms and upgrading multi-axis linkage technology to further improve machining accuracy and efficiency. Simultaneously, efforts are underway to integrate supporting units like spring grinding and tempering, forming a complete production line system. Furthermore, by incorporating industrial internet technologies, remote equipment monitoring and intelligent operation and maintenance are being realized, better adapting to flexible manufacturing and personalized production needs, thereby continuously leading technological innovation in the spring manufacturing industry.
