Chicago Dreis & Krump IPR Series Plate Bender

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 our special hydraulic powered “quick gap set” is a real time saver during set up. The pinch roll is also tilt-able 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.
