2.7. FITTINGS - Foreword
To improve the feeder performance and increase its versatility, a
few optional devices are available which are listed and then de-
scribed below.
2.7.1 Bush-holder device - Description
2.7.2 Axial displacement device - Description
2.7.1 Bush-holder device - Description
It is attached to the front part of the bar feeder. Its func-
tion its to reduce bar vibrations to a minimum, by keep-
ing the bar centered during rotation through two half
bushes
A, which are coupled to form a round channel
with a diameter just slightly larger than that of the bar
being machined.
In many cases, this device can be used (by only
changing the diameter of the half bushes) to greatly
extend the range of diameters which can be machined
without having to replace the guide channel.
Operation
•
When the bar is dropped into the guide channel, the
two half bushes are open.
•
Closure is controlled by a pneumatic cylinder after
the feeder has completed the bar feeding cycle. Clo-
sure also controls lubricating oil flow for lubrication
and machined bar support purposes.
•
When the bar-pusher approaches the device, the
half bushes open up to allow its passage; oil flow is
then discontinued.
