Machine Overview
In the heat exchanger manufacturing industry, many U-shaped hairpin tubes are needed. Traditional U-tube bending machines rely on hydraulic stations for drive, which consume a lot of energy and generate a lot of noise. It isn’t easy to ensure the consistency of products in production.
Especially, it’s difficult to control the angle of the complex-shaped U tube. To solve this series of problems, our servo motor-driven bending machine was born, a revolutionary equipment in the current heat exchanger industry.
The machine is Installation with a servo motor from a well-known brand, which has a reasonable gear speed ratio and outputs mighty power. It achieves a 45% reduction in energy consumption and does not generate noise during production.
The key parts of the bending position are designed modularly, which raises the efficiency and stability of replacing tools to a whole new level. This design not only realizes the low-cost production of multi-size applications, but also improves quality stability.

The advantages of tube bending machine
High-precision manufacturing
As we all know, the gap between the heat exchanger fin holes and tubes is minimal, which puts higher demands on the bending angle and verticality of the hairpin tubes. Otherwise, the tubes cannot be smoothly inserted into the fin holes. Therefore, CHANGHENG’s bending machine uses a servo motor to drive the bending tool, and the bending angle can be freely set, and the angle error will not exceed 0.1%.
Improvement of production efficiency
The tube return device is automatic, and the single cycle time is about 10-12 seconds. Compared with traditional machines driven by hydraulic presses, its production efficiency has increased by 3 times.
Free angle control
Since a servo motor drives the bending device, users can set the bending angle through a touchscreen. Whether your tube is U-shape or 7-shape, this machine can easily complete the production task.
Flexible adaptation
The bending device is modularly designed, so the machine can support a pipe diameter range of φ5-φ20mm, and the supported tube wall thickness is 0.2-0.8mm. This size range almost covers all metal tubes in the heat exchanger industry.

The advanced features of the Tube bending machine
- Intelligent control
The machine is Installation with a 7-inch touchscreen, which can preset multiple sets of bending angles and the length of material withdrawal, and supports the setting and recording of production.
Engineers only need to input the target output. When the output recorded by the equipment meets the requirements, it can automatically stop and emit an alarm sound.
- Customized design
The machines provided by CHANGHENG accept deep customization services. Customers only need to adjust parameters according to their production needs, such as the hairpin tube’s center distance, the bending angle and radius, and the tube’s length etc.
- Early warning system.
In order to keep the tube bending machine running smoothly for a long time, it is equipped with many sensors to monitor the operation of the equipment in real time.
If the motor is overloaded, workers operate illegally, there is a positioning offset, or the pipe material gets stuck, etc., the machine will automatically stop running and issue a warning to avoid damage to the machine and waste of materials.
The application scenarios of Tube bending machines
Heating, Ventilation, and Air Conditioning: used in manufacturing U-shaped heat transfer metal tubes, which are typically used in heat exchangers, evaporators, and condensers.
Refrigeration system: The heat exchange pipeline in processing cold chain equipment and the refrigerant circulation pipeline.
Automobile manufacturing: Pipelines need for the cooling system of new energy vehicle batteries and core pipe parts of the engine radiator.
Industrial waste heat recovery: This industry requires many metal tubes for circulating chemical media.
Summary
The hairpin Tube bending machine launched by CHANGHENG marks the realization of efficient and intelligent production of U pipes. Through the combination of precision manufacturing technology, an intelligent control system, and modular design, we solved the technical problems of high energy consumption and noise. We improved the production efficiency and the stability of quality.
Whether you want to improve your automation production level or meet the demand for output, choosing this equipment will become your core productivity.
