Custom Design & Build
Lomar engineers integrate 2 - tube endformers, a rotary draw bender, a CNC bender and 2 -inspection stations for 1/2" aluminum tube.
Process: Tube is hopper feed to a
pick & place transfer system to a rotary draw bender with a mandrel which
completes a 90° bend on one end of
tube. Tube is transferred to a 3-hit endformer for endforming a stop
bead, inspected, then transferred to 2nd bender (Chiyoda) via 6 axis
robot. Two additional bends are added, then robot transferred to a
2nd tube endformer to complete a endbead, inspected and then dropped onto
a unload conveyor.

To reduce product handling and improve efficiency.
Lomar designed an automated tube notching machine that consisted of: an
adjustable tube hopper for variable part lengths, length check for tube,
notching station, tab bending station and auto unload. Part to part
cycle time was just under 7 seconds.
Brazing application required unique part fixtures,
quench system and part dry off to be integrated with customer supplied
brazing unit. Lomar design and built several of these systems to
braze a carbon steel oil feed line to an alloy block.
Lomar engineers integrated a standard off the shelf cut
off saw with a Lomar Digital Length Gage and provided an extended table
for tube support. Digital length gage provides precise measurement
of tubing, automatic pneumatic clamp blocks hold tube in position during
the cut off.
Servo controlled Hose Cut-Off Machine easily adjust
for various hose diameters and lengths. Operator controls accelerate, decelerate and
payoff speeds.

To meet customers production requirements and cost
out/reduction in there existing process. A turn-key system was
designed which consisted of tubing pulled from coil and straighten, cut to length, auto loaded into first Lomar S1138 Rotary Endform
System, for multiple endforms, roll grooves and ferrule bead lock.
Tube transferred to second Lomar S1138 Endformer for multiple endforms and
fitting placement. Part to part cycle time is 7.0 seconds.
Assembly of charge port, peanut fitting and tube to accumulator can is accomplished with this custom designed weld station. Components are hand loaded into part fixture and cycle initiated. Stepper motors index the part and wire welder tip to weld each component in place. Weld curtain is automatically pulled into position to protect operator during process.
Lomar tube spin closing technology is an alternative to
traditional deep draw process for producing automotive air conditioning
mufflers, accumulators and receiver/dryers. Material capabilities
range from 1" to 3 1/2" diameter aluminum tubing.
