Automatic Tube Expander Machine for Heat Exchanger Coils
Core Purpose & Application Scope
This integrated Portable Tube Expander Machine is a high-efficiency automatic processing equipment specially developed for heat exchanger coil production, with the core purpose of expanding the pipe of heat exchanger coils. It combines precision tube expansion technology and auxiliary bending performance, aiming to solve the key processing needs of copper tube forming and fitting in heat exchanger manufacturing. Whether it is household air conditioning heat exchangers, industrial HVAC heat exchangers or small chiller heat exchange components, this machine can complete stable and efficient pipe expansion operations, ensuring tight bonding between copper tubes and heat exchange fins, tube sheets and other accessories, effectively improving the sealing performance and heat transfer efficiency of heat exchangers.
As a representative Portable Heat Exchanger Expander, it not only has the flexible mobility of a Mobile Expander, but also absorbs the structural stability of a Horizontal Tube Expander Machine, breaking the limitations of traditional fixed expansion equipment. It is suitable for assembly line production, on-site maintenance, small-batch customized processing and other multiple scenarios, truly realizing efficient processing with strong adaptability.
Main Technical Parameters
This automatic tube expander is equipped with optimized parameter configuration to meet the diversified processing needs of heat exchanger manufacturers, with core main parameters as follows:
- Applicable Copper Tube Diameter: Φ7-Φ25mm. This diameter range covers all mainstream copper tube specifications for heat exchanger coils, compatible with thin-walled copper tubes, conventional standard copper tubes and other common materials. The automatic expansion mechanism ensures uniform force during the processing, avoiding common defects such as tube cracking, deformation and dimensional deviation, and realizing high-precision forming of pipes of different diameters without frequent replacement of tooling.
- Expansion Length: Customizable according to buyer's requirement. The machine adopts adjustable positioning structure and intelligent control system, which can accurately set and control the expansion length according to the actual size of heat exchanger coils. Whether it is short-distance local expansion or full-length integral expansion, it can be flexibly adjusted, fully matching the personalized processing requirements of different styles and structures of heat exchangers.
- Expansion Speed: 5-11meter/ min. Equipped with an efficient automatic drive system, the expansion speed supports stepless adjustment, which can be set according to copper tube diameter, material thickness and processing accuracy requirements. This speed range takes into account high production efficiency and stable processing quality, ensuring continuous and smooth operation of the equipment and greatly improving the production efficiency of heat exchanger coil processing lines.
