*Machine as equipped is guaranteed to form a 1-3/4" thick mild steel plate to
24" diameter x 10' long steel tube with flats not exceeding two times metal
thickness or 3-1/2". When equipped with standard 25" top roll this machine has
a rated capacity of 2-5/8" mild steel plate plate to 60" diameter x 10' long.
The entire machine and gearcases are designed and built by WDM staff. WDM has
been continually building rolls for the last twenty three years. WDM has well
over 1000 machines in the manufacturing field.
HEAVY DUTY DRIVES
The high torque drives are designed and manufactured to provide the very high
forces required to enable the operator to roll 24" tubes in one pass. These
gear cases are of robust design and manufactured locally by Wildcat Ridge
The hydraulic system is designed using mainly standard, off the shelf American
made components. The large bending roll cyclinders are manufactured by WDM
using standard seals and replacement items. Off the shelf components are used
whenever possible throughout the entire system. The hydraulic fluid is
filtered when leaving and again when returning to the tank.
SPECIAL SMALL DIAMETER TOP ROLL
The top roll is accurately machined from a chromium molybdenum alloy steel,
through hardened to 28-32 RC, with the surface flame hardened to 55-60 RC,
.150" to .200" deep.
OVERHEAD SUPPORT SYSTEM
The overhead support system stiffens the top roll during the pre-bending
stages of the forming operation. It can be moved out of the way to complete
the less stressful finish bend. Should the support not be required for the
operation, it can be rotated 100 degrees out of the way. The support can also
be raised 48" to provide clearance for smaller diameter tubes.
WDM uses premium efficiency electric motors and well designed hydraulic
systems to conserve energy. In the interest of energy conservation, this
machine will be equipped with dual 30 HP systems in lieu of one 60 HP system.
Because of the relatively small size of the work piece, we believe only one 30
HP system will be required to provide satisfactory performance. The second
unit will be available any time time higher speeds are required.
