CHICAGO DREIS & KRUMP Model IPR 4250 Bending Roll 50"
Chicago Dreis & Krump offers initial pinch bending rolls for
rolling sheet metal and light plate. Initial Pinch Rolls
with electric/hydraulic power are capable of rolling full or
partial cylinders from 16 gauge mild steel to 1/2 inch
plate. The lower pinch roll with the special hydraulic
powered "quickgap set" is a real time saver during set up.
The pinch roll is also tiltable for cone rolling. Hydraulic
operation of the drop end for ease of material removal is an
added convenience.
As with all Chicago bending rolls, the frames are made of
heavy welded construction. The rolls are made from forged
steel and heat treated to RC 45. Spherical roller bearings
on all three rolls minimize friction loss. The rear bending
roll is equipped with an LED readout indicting its position
for accurate forming. Positioning of the rear bending roll
is done hydraulically and allows the operator to tilt it for
cone forming. An emergency stop button and keylock on/off
power switch are centrally located on the control panel.
