AC Coils Bender Fully Auto Return Bending Machine

I. Equipment Application

This copper tube bending machine is a specialized processing equipment integrating multiple processes. Its core functions cover automatic uncoiling, precise straightening, length cutting, and U-bending of coiled copper tubes. It can process continuous coiled copper tubes into U-shaped bending tubes that meet assembly standards in one go, achieving one-stop processing from raw materials to finished products. This equipment is specifically designed for the thermal equipment manufacturing industry and is mainly used in the core pipeline processing scenarios of products such as air conditioner condensers, air conditioner evaporators, storage water heaters, and instant water heaters. In the production process of air conditioners, water heaters, and other products, the U-shaped bending tube is a key connecting component for constructing heat exchange circuits. Its processing accuracy directly affects the sealing performance of the pipeline assembly, heat exchange efficiency, and overall machine operation stability. Traditional processing methods require multiple independent machines to complete the uncoiling, straightening, cutting, and bending processes separately. This not only results in cumbersome process connections and significant material transfer losses but also easily leads to poor product dimensional consistency due to adjustments in multiple machines. This equipment, through multi-process integration and automated control, effectively solves the pain points of traditional processes, significantly improving processing efficiency and product precision, providing core support for large-scale, standardized production in industries such as air conditioning and water heaters.

II. Core Specifications

The equipment specifications have been specifically optimized to flexibly adapt to the processing needs of different models of thermal equipment, balancing production efficiency and processing quality. Specific parameters and advantages are as follows:

- Compatible Copper Pipe Diameter: Φ5-22mm: This parameter accurately covers the commonly used copper pipe specifications for mainstream thermal equipment's U-shaped bends, comprehensively adapting to processing needs ranging from small-diameter copper pipes (e.g., Φ5mm, Φ7mm) for small household air conditioner evaporators, to medium-diameter copper pipes (e.g., Φ12mm, Φ16mm) for commercial central air conditioner condensers, and large-diameter copper pipes (e.g., Φ19mm, Φ22mm) for large storage water heaters. The equipment is equipped with quick-change adaptive tooling fixtures, eliminating the need for complex mechanical adjustments. Simply call the corresponding parameter template in the control system to quickly change between different pipe diameters, significantly improving production versatility and flexibility, and reducing debugging costs for multi-variety production.

- Number of pipes bent per cycle: 2, 3, or 5 pieces selectable: Adopting a multi-station modular design, it provides three different single-bending speeds to precisely match the production capacity and scenarios of different users. Each speed uses synchronous drive technology to ensure that multiple U-shaped pipes bent in the same batch are completely identical in size, guaranteeing consistency in mass production.

- Processing speed: 8-10 times/minute: Utilizing an optimized transmission mechanism and parallel process design, it achieves high-speed and stable continuous processing. This speed range can be flexibly adjusted according to the diameter, wall thickness, and bending accuracy requirements of the copper pipes being processed.

- Customized parameters: More parameters can be customized according to actual copper pipe specifications and needs: Considering the differentiated product needs of different users, the equipment supports comprehensive customization services. In addition to the standard parameters mentioned above, core components (such as bending dies and cutting tools) and control programs of the equipment can be customized and optimized according to the user's specific requirements for copper tube material (such as red copper and brass), wall thickness, U-tube opening size, bending angle tolerance, and cutting length accuracy. Furthermore, the machine body size and feeding/discharging methods can be customized according to the user's workshop layout and production line connection needs to ensure the equipment perfectly matches the user's personalized production requirements, improving the equipment's adaptability and practicality.
