Auto Deburring Cleaning Machine for U-Bend Tubes

This equipment is a highly integrated multifunctional processing machine, combining metal polishing, deburring, cleaning and hairpin bending in one unit, specially developed for the refined processing of heat exchanger small U-shaped pipes (hairpin pipes). It breaks the traditional single-process processing mode, realizing the one-stop forming and surface treatment of key heat exchange pipeline parts, and becomes a core supporting equipment in the heat exchanger pipeline production line.

Purpose

This machine is mainly used for high-precision deburring and deep cleaning of small U-shaped pipes for heat exchangers, and can also synchronously complete the standardized hairpin bending forming of pipe fittings. Targeted at the defects such as burrs, oil stains and metal debris left after pipe bending, it thoroughly removes impurities and sharp edges, effectively improving the sealing performance and heat exchange efficiency of finished pipe fittings. It can perfectly connect with the front-end Automatic Return Bending Machine (also known as Automatic Return Bender) for semi-finished product supply, and its post-processing effect is fully compatible with the process standards of special Return Bend Cleaning Machine, providing a reliable quality guarantee for the subsequent assembly of heat exchanger pipelines.

Working Process

The Cleaning Machine For Return Bend machine adopts fully automatic continuous operation logic, without manual handover in the whole process, realizing smooth and efficient processing from raw parts to finished products. The complete processing flow is as follows:

- Automatic Feeding: The raw pipes or semi-finished bent parts are automatically and orderly conveyed into the processing station, ensuring stable and continuous feeding and matching the production rhythm of the Automatic Return Bender.

- Deburring & Cleaning & Polishing: Integrated polishing and deburring treatment is carried out on the pipe ends and inner and outer walls, combined with deep cleaning to remove oil stains and debris, achieving the same cleanliness as the special Cleaning Machine For Return Bend.

- Clean Water Rinse: Thoroughly rinse the residual cleaning agent and impurities on the pipe surface to avoid affecting subsequent assembly and use performance.

- Rapid Drying: Use hot air circulation drying to quickly remove moisture inside and outside the pipe, preventing secondary contamination and rust.

- Automatic Discharge: The processed qualified U-shaped pipes are output in a centralized manner, facilitating subsequent collection and assembly operations.

Product Advantages

- High Integration: Integrates bending, polishing, deburring and cleaning functions, reducing equipment layout space and workpiece transfer time, and improving overall production efficiency.

- Strong Line Compatibility: Can be seamlessly embedded into the return bend processing line, cooperating with Automatic Return Bending Machine and special cleaning equipment to form a complete automated production system.

- Stable Processing Quality: Uniform deburring and cleaning effect, no damage to the pipe body, suitable for mass and stable production of small U-shaped pipes for heat exchangers.

- Fully Automated Operation: Simple operation, low labor intensity, stable equipment operation, effectively reducing the defective rate of pipeline parts.

Application Scope

Widely used in the manufacturing of air conditioners, refrigerators, industrial chillers and other heat exchange equipment, dedicated to the forming, deburring and cleaning of small U-shaped hairpin pipes, and can be used in conjunction with supporting bending and cleaning equipment to meet high-standard industrial production needs.
