Electro Mechanical Pyramid Type Plate Bending Machines are the
most popular plate bending machines working in India with over
a thousand machines in use.
They are designed for production of cylindrical shells used
for pipes, storage tanks, chimneys, pressure vessels, etc.
These heavy duty plate bending machines employ the orthodox
three roller pyramid principle. Bottom rolls are fixed and are
driven by a system of gears and worm reduction gear box
whereas the top roll has a vertical up and down movement
through (a) Screws adjusted manually in model TPH. (b) Separate
Motor + Reduction gear box in model TPVP. The housings are
steel fabricated with large bearing surace area. The rolls are
of wear resistent forged steel and are amply dimensioned to
keep deflection to the minimum. Screw jack is provided to keep
the top roll horizontal when the formed shell is to be
extracted by retracting the trunion. Horizontal grooves are
provided throughout the length of rolls for additional
gripping and correct feeding. Indicators are provided at both
ends for correct top roll pressure.
(For Model TPVP) For conical bending the top roll can be
inclined disengaging the clutch at one end of the Wsorm Gears |
