DEMO WDM HYDRAULIC PINCH PYRAMID ANGLE BENDING ROLL
MODEL AR31 ♦ YEAR: 2013
Stock No. 9474
This Machine is constructed at our plants here in Liberty, KY, using
predominantly domestic and many off-the-shelf components.

The Frame is fabricated from structural steel and plate sections, then
machined at all main and critical areas, providing a rigid, durable, and
practical framework for the machine.

The Arbors/Shafts are of heat treated chromium/molybdenum steel and are of
ample size to carry bending loads with minimum deflection.

The Bearings are of rolling element type, which results in minimum power
loss; and the main bearings are of sealed spherical roller type, which
are inherently self-aligning to compensate for shaft and frame deflection.

The Drives are either directly driven with hydraulic motors or through
in-line type planetary drives with overall efficiency in excess of 95%
Each arbor/shaft is individually driven and equalized hydraulically.

Roller Speed is infinitely variable from 0 to 23 max. on all machines.

Roll Adjustment speed is also infinitely variable from 0 to max. on all
machines. On Model 41 and larger, this adjustment is independent of
rolling speed adjustment.

Standard Dies are accurately machined and through hardened for long life.
Standard universal dies allow the user to roll angle leg in and leg out,
tees leg in and leg out, flat on flat and on edge, and square bars.

Special Dies allow the user to roll round bars, pipe, and tubing in
circles or spirals, I-beam and channel can be rolled on flange or on edge.
Some WDM machines have been fitted to roll the following: aluminum
extrusions, airfoil shaped pipe, high ratio flat on edge, and half
pipe on strip

Guide Rolls are through hardened steel and run on rolling element
type bearings. On the small machines, they are adjusted manually.
The larger machines have either partial or complete hydraulic adjustment.
(See specifications section)

Operating Position All machines up to the Model 60 can be operated in
either horizontal or vertical positions, with shafts extending either
upward or outward from machines. Larger models must be built for one
or the other operating position.

Hydraulic System is of quiet design and uses state-of-the-art type
components with the reservoir in integral part of the machine frame.
This results in added heat dissipation.

Lubrication annually at most points is adequate for normal operating duty.

Electrical system is housed in NEMA 12 type enclosures. It is installed
to the NFPA 79 code.

Machine Functions are controlled via push button type controls mounted
on control pendant. Special controls are available.

Roll Position indicators are of dial/pointer type, as standard.
The machine can be fitted with some of our Series 42 Controls which
offer electronic digital readout(s) with or without presets.
