HOGI servo ring making machine (also known as a fully automatic servo circle clamps or CNC servo ring making machine) is metal wire/tube processing device that uses a servo motor to precisely control wire feeding, coiling, and cutting. It is widely used to continuously coil metal wires clamps (such as steel wire, iron hoops, copper wire, and stainless steel wire) into circular, elliptical, or polygonal loops.
I. Key Features and Technical Advantages
* High-Precision Control: The wire feeding mechanism is driven by a servo motor, achieving a feeding length accuracy of ±0.1 mm with minimal tolerances for circumference and diameter, thereby resolving the issue of cumulative errors common in traditional mechanical coiling machines.
* Digital, Intelligent Operation: Equipped with a PLC and touchscreen human-machine interface (HMI), the system automatically calculates pulses and completes processing upon inputting the wire diameter, loop diameter/circumference, and production quantity, eliminating the need for frequent mechanical gear adjustments.
* Multifunctional Integration: Combines automatic straightening, precise wire feeding, coiling, and hydraulic/servo cutting into a single unit. Some high-end models support “coiling + automatic butt welding (butt/lap welding)” in a continuous production line.
* Flexible Processing: Supports forward and reverse wire feeding as well as multi-segment curve control, enabling the production of not only closed loops but also semicircles, arcs, ellipses, and irregular shapes.
II. Working Principle and Structural Components
* Straightening Mechanism: A set of longitudinal and transverse straightening rollers removes bending stress from the wire, ensuring smooth wire feeding.
* Servo Wire Feeding Mechanism: A servo motor drives high-hardness wire-pressing rollers to achieve precise, slip-free, fixed-length wire feeding.
* Forming Mechanism (Forming Claws/Crank Wheels): Based on the preset curvature, the forming wheels work in conjunction with the guide wheels to bend the metal wire to the desired diameter.
* Cutting Mechanism: Once the coil reaches the set circumference, a hydraulic or servo-driven cutting tool instantly severs the wire, completing the single-coil processing.

Servo Ring-Making Machine
Also known as: Coiling Machine, Ring-Making Machine, Wire Coiling Machine. The mainstream design features servo wire feeding combined with hydraulic cutting. Compared to older hydraulic ring-making machines, it offers higher dimensional accuracy in wire feeding, better consistency in ring diameter, and lower noise levels.
Applications
Processes iron wire, galvanized wire, stainless steel, copper wire, and flat iron to form full circles, half-circles, and multi-coil spirals;
Applications: barrel hoops, dust collector cages, fan guards, rebar benches, metal crafts, guardrail components, etc.
Core Structure
1. Straightening Mechanism: Multiple sets of rollers straighten the wire
2. Servo Wire Feed Shaft: A servo motor and encoder control the feed length, determining the precision of the coil circumference
3. Forming Die Wheels: Replacing the dies changes the finished coil diameter
4. Hydraulic Cutting: Hydraulic shears cut the material after forming is complete
5. PLC Touchscreen: Input wire diameter, coil diameter, and quantity; Chinese and English interfaces; supports manual, automatic, and jog mode debugging
6. Optional Configurations: Integrated loop-forming and butt-welding machine, specialized dies for flat iron, automatic unloading
* Cutting Methods:
* Hydraulic cutting: High torque, moderate cost; suitable for medium- to thick-gauge wire.
* Servo cutting: Faster speed, low noise, oil-free; suitable for applications requiring high cleanliness or high-frequency, high-speed production.
* Automation Expansion Options: Determine whether to integrate an automatic feed rack, robotic part retrieval, or automatic butt-welding mechanism to form an automated production line.
HOGI’s independently designed fully automatic loop-forming and butt-welding machine leads the industry in terms of functionality, stability, quality control, and precision. Featuring hydraulic cutting, resistance butt welding, and servo control, it fully automates the entire production process—from loop forming to cutting and welding. Furthermore, this loop-forming machine supports fast, slow, and feed modes; with servo control, it operates fully automatically once the parameters are set. The machine incorporates imported components, significantly extending its service life.
