ROTARY BRAZING
MACHINES
The rotary table brazing machine has been designed to allow rapid brazing
of copper/brass joints used in a variety of industries and also general spot heating and
hardening. The heating section is gas fired and can be used with low pressure Natural gas
or L.P.Gas. There are several models available with the main variance the number and type
of heating stations, provision of air and water cooling, the automation of the process and
the jig design. Various burner tip combinations are possible within capacity and other
machine limits.
Australian Combustion
Services Pty Ltd will provide an evaluation and recommendation from samples supplied.
PREMIX BURNER TIPS
There are
an assortment of burner tips available for the brazing machines with a variety of flame
shapes.
All are classified as
premix tips necessitating the appropriate air and gas-mixing device with individual air
and gas control valves.
JIGGING
Australian Combustion
Services Pty Ltd usually supplies full stainless steel jigging depending on the individual
contract and the customer's capabilities.
Our jig designs
incorporate several proven features to ensure fast changeovers, accurate positioning and
solder run and multiple joint capabilities where possible.
The standard rotating
machine arms incorporate a standardised jig base bar.
Two pins are used to
enable fast jig changing and interoperability between
machines and parts
PASTE BRAZING AND
SOLDERING SYSTEMS
Automatic paste
applicators provide accurate, repetitive positioning of braze paste on the joint.
These are usually fitted to rotary machines at a free station prior to the heating section
but have also found uses in standalone systems.
INFRARED TEMPERATURE
SENSING
The most
common method of cycling is using a timer to either remove the heat source or reduce the
flame to a low setting.
A better, more accurate approach utilises an infrared temperature sensor interfaced with
an accurate digital readout.
This is connected to the existing heat reduction or removal method.
The sensor is
positioned to monitor the actual joint temperature and ensure wastage is reduced. Changing
ambient temperatures, product changeovers, set up times and unauthorised adjustment of the
machines can cause waste. A more serious problem occurs if the alteration is not attended
to and faulty product slips through unnoticed. Although the unit will automatically
compensate the heat source for any departure from the required setting, an alarm can be
connected to warn the operator.
