Hydraulic Vertical Tube Expanding Expander Machine For HVAC Equipment
Hydraulic Vertical Tube Expanding Expander Machine for HVAC Equipment Air Conditioners
1. Feature of structure
The heat exchanger tube expander machine adopts vertical arrangement, load and unload work piece lift door,
which can expand, flare and fold tubes in one cycle.
Length adjustment of second expansion is done by motor reducer, sprocket and chain which drive thread bar
to rotate synchronous, thread bar connect with coder and the length change can be showed on the PLC
terminal screen. The vertical tube expanding machine is a professional machine involved in HVAC production lines.
2. Technical Parameters of Vertical Expander

4.Standard of acceptance
Tolerance between top side and low side of work piece after expanding:
If the width of work piece ≤800mm, the tolerance is 0.8mm. If the width is more than 800mm
tolerance is 1/1000mm width of work piece.
Tolerance between left side and tight side of work piece after expanding:
If the length of work piece ≤800mm, tolerance is 0.8mm. If the length is between 800-1200mm
tolerance is 1mm. If the length is over 1200mm tolerance is 1/1000 length of work piece.
The length tolerance after expanding:
If the length of work piece ≤1200mm, tolerance is less than 1.2mm. If the length of work
piece ＞1200mm, the tolerance is 1/1000 length of work piece.
After flaring and folding the tolerance is: ≤Φ0.2mm.
Work piece should move steadily.
The max. expanding capacity of expanding, flaring and reflare tubes IN ONE STROKE: 220holes.
