Automatic Tube End Expanding & Shrinking Machine
Intergrated machine to save labor.
Adjustable Feeding Hopper.
Customizable Feeding Stroke to meet different tube length and diameters.
The Automatic Tube End Expanding & Shrinking Machine is a highly efficient and versatile equipment designed to streamline the process of expanding and shrinking tube ends. It incorporates an automatic feeding device that allows cut pipe codes to be placed in the hopper, enabling the machine to complete the feeding process automatically. The feeding device utilizes a linkage structure to ensure precise and consistent feeding, processing one pipe at a time and eliminating material piling.

Features
This advanced system specializes in precision tube end forming for copper and aluminum tubes (Ø3–8mm diameter, 70–400mm length). Featuring a PLC-controlled automatic feeding hopper with adjustable width and pneumatic gripper transfer, it achieves 4–5 tubes/minute with ±0.05mm inner diameter tolerance. The rotary forging shrink head with casting shell ensures deformation-free processing while reducing operational noise, ideal for HVAC and refrigeration component manufacturing.
Intelligent Automation & Material Handling
The machine automates the entire workflow—from adjustable hopper feeding (70–400mm tube length) to pneumatic gripper transfer and unloading. Its linkage-based feeding mechanism prevents material jamming while the integrated tube detection system eliminates misfeeds, ensuring uninterrupted production and high throughput.
Precision Forging with Deformation Control
Equipped with a rotary-forged shrink head and custom cutting dies, the system maintains Φ1.9–10.0±0.05mm inner diameter accuracy. A patented tube-holding clamp secures materials during expansion/shrinking (30–50mm processing length), preventing distortion even at high speeds.
Flexible Configuration & Quiet Operation
Operators can customize feeding strokes via the HMI interface and rapidly adapt to varying tube dimensions. The vibration-damped forging structure and noise-optimized dies reduce sound emissions, enhancing workplace comfort without compromising the 2.2KW motor’s performance.
Industrial-Grade Durability
Built with heavy-duty casting components and a rigid 860kg frame, the machine withstands continuous 380V/3-phase operation. Maintenance-friendly access points and alloy tool heads extend service life for demanding production environments.
