China SX-120T Automatic Bonell Transfer Machine - Advanced Spring Production Equipment from Reliable Suppliers & Factory

Product Information
SX-120T Automatic Bonnell Transfer Machine
SX-120T is a fully automatic production equipment for Bonnell spring cores with a higher degree of intelligence. Adopting a servo system based on bus control, it can realize the positive and negative arrangement of any spring with advanced functions and performance. The production efficiency reaches about 120 Bonnell springs coiled and assembled per minute.
SX-120T significantly streamlines the production process. Its intelligent features enable seamless operation, reducing human intervention. As a result, it becomes a game-changer for manufacturers aiming to boost productivity and maintain top-notch quality in Bonnell spring core production.
In a single cycle, the wire is coiled, shaped, heat-treated, face-to-face transferred, and assembled into a unit. The system is fully integrated with a digital servo control system.
Core Performance
- Special face-to-face assembly: Solves all incline issues that occur when pressing Bonnell units.
- Customized spring shapes: Available on request to meet specific production needs.
- High Speed: Operates at 110-120 springs/min.
- Roll Packing: Perfectly optimized and suitable for roll packing.
- Helical wire clamping: Available as an option.
Spring Direction Control
Supports multiple alignment configurations:
- Standard setup
- Face-to-face assembly
- Alternating row knots (one row knots face left, one row knots face right) which minimizes the diagonal line deviation to less than 1cm.
- DIY setup (e.g., 5 spring knots face left, 5 spring knots face right).
Frequently Asked Questions (FAQ)
QWhat is the maximum production speed of the SX-120T?
The SX-120T features high-speed operation, coiling and assembling approximately 110 to 120 Bonnell springs per minute.
QHow does the face-to-face assembly solve the incline issues?
By utilizing a specialized face-to-face transfer and assembly design, the machine eliminates the physical inclination that typically occurs when pressing assembled Bonnell spring units.
QWhat spring direction control modes are available?
The machine offers four modes: Standard mode, Face-to-face assembly, Alternating row knots (one row left, one row right to limit diagonal deviation to under 1cm), and custom DIY configurations (e.g., 5 knots left, 5 knots right).
QAre the spring cores produced by this machine suitable for roll packing?
Yes, the structured alignment and high-quality assembly of the spring cores produced by the SX-120T make them highly suitable for roll packing.
QWhat processes are integrated into a single machine cycle?
In one continuous cycle, the SX-120T automatically performs wire coiling, shaping, heat treatment, face-to-face transferring, and final assembly into a complete unit.
QCan I customize the spring shapes with the SX-120T?
Yes, customized spring shapes can be accommodated and configured upon request to meet your specific manufacturing needs.
