Akyapak Model AHS Hydraulic
Four Roll Plate Bending Machines

Design & Standard Features of the Akyapak Model AHS:

Design:

• Four Roll design, reducing end flat, permitting single part entry and providing ease of plate alignment against side roll.

Drive:

• Top and pinch rolls individually driven via planetary gear reducers and hydraulic motors
• Automatic surface speed compensation between top and pinch rolls
• Drive protected against overload by relief valves

Electrics & Motors:

• Electric motor is totally enclosed, fan cooled type.
• Motors and other electrical equipment operate on 240/3/60 or 480/3/60 volts
• All operator controls are low voltage

Digital Readouts:

• Two digital readouts are provided, indicating precise position of the two adjustable side rolls.

Roll Adjustment:

• All three adjustable rolls are independently, hydraulically adjustable via push button on the operator’s console
• Leveling system insuring parallelism of all three adjustable rolls
• All three adjustable rolls have the ability to tilt, controlled directly from console
(Optional cone rolling attachment must be purchased to tilt rolls)
• Pinch roll set to adjustable pinch pressure

Roll Rotation:

• Machine supplied with two speed rotation, controlled by selector switch on operator’s console.

Bearings:

• All roll journals are mounted in roller bearings reducing friction and maintenance

Drop End:

• Hydraulically operated drop end (hinge) controlled from operator’s console
• Top roll raises when drop end is lowered for ease of part removal

Operator’s Console:

• All operator machine functions located in movable type console
• Functions include; roll adjustment, roll rotation, roll rotation speed, open / close of hinge and digital readouts.
• All roll movements are controlled by push buttons.

Safety:

• Emergency stop cable around perimeter of machine.
• Emergency stop button on operator’s console.
• Fixed steel guard around drop end.
• Instant braking of roll rotation when pushbutton is released.
