Model No.: SFP-2500
Specification of SHP Hairpin bender
Tube specification: 4 * 3/8" & 4* 1/2"
Length of hairpin: 200-2500
Structure & operation:
SHP8-2500 Model hairpin bender quoted here consist of:
1. Powered uncoiler station
2. A changeable rerounding & straightening system to allow for further diameter changes.
The rounding & straightening wheels are set on both the vertical and horizontal plane,
which will straight the tubes from the 2 plates. Each tube has 2 rounding wheels and 12 straighten wheels
The feeding system is a hydraulically driven friction feeding device, with air cylinders
controlling the actual pressure applied to the individual feed belts. When
feeding, individual air cylinders will apply proper pressure to each of the
belts. The upper and bottom belts will clamp one copper tube and feed to proper
length.when the proper length is almost achieved. The feeding speed will change
from fast to slow, and the air cylinder pressure on the belt will change from
high to low. Each air cylinder will lose almost all pressure when the tube it
is feeding reaches the final proper position against a Hard Stop plate. It will
hold that tube in place until all tubes have achieved the final proper
position. Thus all hairpin ends are in the same final location assuring both
the consistence of hairpin length and equality of leg lengths
3. A fixed location cutting system
The copper tubing cutting system utilizes outer rotating cutter blades to cut the tube. Lubrication takes place.
The feed belts reverse and separate the tube ends after cutting.
4. A Bending system
The bending system can move in
the length direction to produce hairpin of different lengths. The leg length is
set from the PLC and Programming is fully automatic
The bend system is servo driven.
This is allows for much better accuracy and less free play or back lash then the older type of
hydraulically driven bending heads found in many competitor's units.
5 In addition:
Change" Tube support booms are provided to support the guide tubes and
allow change from one length to another in less than 2 minutes
The Hairpinbender will be capable of receiving such special sets of bend tooling as may be
dictated by specific bend radius requirements and / or changes in tubing
diameter up to16mmmaximum.
A sensingdevice is provided in each lubrication tank to monitor the level of oil to
prevent operating the equipment without proper lubrication. A corresponding
diagnostic message will be displayed on the touch screen when the level is low
An tube pickoff device is included which will support the tubes while stripping and lay
them down in the tube collectors. This will produce straighter hairpins for
There is a tube end Sizer attachment to reopen the ends of the hairpins
that do not passover the mandrels
Automatic setup of the hairpin bender and leg length adjustments can be accomplished
through the use of a standard programmable controller interfaced with a touch
screen. This also provides diagnostic information for trouble shooting, Semi-automatic
control and manual actuation of all machine functions.
Additionally, The machine is capable of
automatically positioning to specific hairpin length. Both legs of hairpin are adjustable through
the touch screen and can be moved either independently or together by dedicated servo
motors. The motors are capable of running at both fast and slow speeds to decrease
setup time and facilitate precision adjustments. Over-travel switches on each axis help
protect the machine with digital readouts on the touch screen display the current and
target location in increments of 0.1mm. After the target location on each axis has been
reached, hydraulic Clamps lock in place to prohibit drifting.
Cable/hose carriers are provided to the back of the machine and the switch tower area to
prevent hose and cable damage and imprve the general esthetic of the equipment
Industry standard assemblies are also supplied-such as
1. Stripper tube pro
