Special Machines for Dedicated Work:
We are the
preferred vendor for multiple companies for special
machines. As clients products are improved and changes
are made we compensate by revising or providing new
equipment.
We
enjoy working with the client during product development
for effective use of: materials, tolerances and
machines. We have found that working early with the
client saves the client labor, materials and capital
costs.
This
is an example of a custom machine unloading blanks from
a stamping press for an automotive manufacture.
This
machine utilizes:
-
Two large Indramat servo motors electronically
linked by PPC controller and belt drives.
-
Our machine matches contuinuous press operation by
montering press resolver. As press comes up to
speed the unloaders match speed perfectly.
-
When press is stopped at end of cycle the unloaders
automatically back out of the press window.
-
The operator uses a human machine interface (HMI) to
control the transfer operation:
-
Height of the unloader to match different dies.
-
Unloader starting
position in front of the die.
-
Distance the unloader travels into the die. Up
to 96” travel one direction each cycle.
-
Maximum strokes per minute, (SPM). System is
capable of up to 45 strokes per minute. We
automatically calculate maximum acceleration,
travel speed and deceleration for the operator.
Press speed is normally determined by the
capability of the operators being able to stack
the blanks; about 25 SPM.
-
We also supplied the cylinder operated knockouts
on the press. Cylinder operation during a cycle
is controlled by operator input on the HMI in
order to discharge the product from the die at
the proper time.
-
Each setting is stored in a recipe for many
different parts.
-
Operator has full manual functions of each
movement available in order to set up a new die
or assist with maintenance.
-
We
supplied two systems for the two new blanking
presses at the plant. Each system has reliably been
used over 10,000,000 cycles to date.
-
The following U-Tube videos were taken in our shop
and at clients plant. In order to demonstrate and
test the machine in our shop we use a press
simulator machine that we constructed.
