HVAC Equipment Servo Vertical Tube Expander Expansion Machine for
Air Conditioners
1. Product Range
WONDERY is a professional manufacturer of HVAC equipment. We have
the full range HVAC equipment
such as high speed fin press machine, automatic vertical tube
expander machine, automatic hairpin bender,
aluminum and copper pipe straightening and cutting machine. We have
auomatic and manual machines to
meet the different production needs in HVAC equipment.
2. Structural features of Vertical Expander Machine
2.1 The vertical tube expander machine adopts vertical arrangement,
load and unload work piece by operator,
which can expand, flare and fold tubes in one cycle.
2.2 Length adjustment of second expansion is done by motor reducer,
sprocket and chain which drive thread
bar to rotate synchronously, thread bar connect with coder and the
length change can be showed on the
PLC terminal screen.
2.3 The lower supporter between the two controlling end plates can
realize rise and descend synchronous
through the motor and worm gear box, Pneumatic lock. You can also
choose lower thread bar rotary coder
so as to realize length change can be showed on the touch screen
screen.
2.4 Expanding rod quick fixed, pneumatic lock and expanding rod
protective device are fixed on the machine.
The protective device will stop operating automatically to avoid
damaging expanding rod, once expanding rod
run into unexpected case and bend.
2.5 Receiver is provided with locking structure, which will not be
pulled out when unload and it is also
convenient for changing the specification. In order to take out the
work piece conveniently.
2.6 The vertical tube expanding machine door use compound structure
of steel and aluminum.
2.7 The vertical tube expander is provided with two guide systems,
guide column and slide guide rail.
The complete machine has good rigidity.
2.8 The whole template is processed by imported machine center with
high precision, which can be
changed with each other when the specification is changed.
2.9 Design A.B.C …… Codes to replace of coil height input for easy
operation
Manager, once customer select the part no, the machine adjust
automatically and the operator does
not have to press any button to move the expander plates up or
down., what’s more set Passcode for
Flare and Reflare Process.
2.10 Expanding shrinkage evenly for Middle Support Plate with +/-2%
under
permitting with fin quantity adjustment.
2.11 Follow customer’s design for bullet locking topic.

4.Standard of acceptance:
4.1 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 1/1000
width of work piece.
4.2 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.
4.3 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.
4.4 After flaring and folding the tolerance is: ≤Φ0.2mm.
4.5 Work piece should move steadily.The max holes can be expanded,
flared and folded in one cycle:
120 holes for Φ7.
