EMT-7R Air Cylinder Operation
The EMT-7R Air Cylinder option is a cost effective way of allowing the operator
hands free operation to maintain full control of the part being formed. This option
is
not recommended for Flanging Rolls or Spin In Collar Rolls as these rolls
require a stepping down of the top shaft and the travel on the air cylinder is
continuous and not able to stop & start during the forming process which is a
requirement for these rolls.
The air cylinder is initialized when the foot pedal is depressed and returns to its
home position when the foot pedal is released.
The air cylinder option comes standard with a closing speed adjustment valve
which is used to control the speed of the top shaft coming together to pinch the
material. Also included is a depth stop adjustment which allows the operator to
stop the top shaft at a predetermined depth for production operations. To adjust the
air cylinder to the desired depth use your thumb and adjust the Knurled Nut which
is located inside the window of the yellow finger guard. Screwing the Knurled Nut
down will shorten the stroke of the cylinder and lessen the depth of the profile
being formed. Raising the Knurled Nut will allow the rolls to come closer together
thereby allowing the profile to be deeper.
If for any reason the air cylinder must be removed to allow the operator to utilize
the standard hand crank that was shipped with your EMT-7R the following process
must be followed. First disconnect the air supply from your compressor to the unit.
Then remove the plastic air line from the top of the air cylinder that is connected to
the end of the speed control valve by pushing and holding the plastic ring in while
pulling on the air line. Next loosen the jam nut (shown in the picture above) and
then spin the air cylinder out of the threaded hole and thread in the hand crank.
