The system offered is comprised of a combination coilcradle-feeder-straightener. The coil cradle and feeder-straightener are both driven by servodrives. The system is designed to run with no loop, the cradle drive and straightener drive are matched electronically.
The servo-drive responds to the press cam switches, and feeds an exact amount each press stroke.
Model 200CSF40 Coil Staging Ramp Cradle Uncoiler, Feeder-Straightener with Servo Pilot Release
-CAPACITY 20,000 LB.
-MAX. OD 72″
-MIN. ID 18″
-MAX. THICKNESS 0.312″
-PASSLINE HEIGHT 52″ TO 58″ POWER ADJUSTMENT
Based on review of the most difficult materials on the specification list we recommend the 6STR40 straightener.
Machine frame and drive sizing will match the straightener capacity listed for the 6STR40 series straightener.
Coil Storage ramp:
-The coil is loaded onto a coil storage ramp waiting for the current coil to run out.
-The ramp raises to create a down slope for the coil to roll toward the cradle rolls in the run position.
– The coil is supported on 2 hardened cradle rolls
– Cradle rolls are driven by a servo-gearmotor
– Cradle side plates are self-centering and are power adjusted.
– the coil rolls into the cradle and is cushioned by the peeler roller as it reaches the cradle rolls.
– the peeler roller is then used to bend the start of coil away from the coil and deflect it into the straightener.
-A six roll straightener is used to provide easier control and adjustment of the material. The last roll allows the operator to fine tune the strip up or down more simply than with 7 or 5 roll style straighteners.
-rolls are 1045 steel, 6.000″ diameter, induction hardened to 56-58 Rc, and diameters are precision ground. Bearings are Heavy Duty needle rollers running on hardened inner races with seals.
-The upper 3 rolls of the straightener are not driven and are individually adjustable.
-Straightener rolls are adjusted by hydraulic motors, roll position is indicated by digital counters with .001″ resolution.
-Feed rolls are 1045 steel, 6.000″ diameter, induction hardened to 56-58 Rc, precision ground, shot peened and chrome coated for excellent wear resistance and grip.
-2 entry feed rolls, upper and lower roll driven, grip the strip to drive material thru straightener without resetting. Upper roll is lifted/lowered by 2 hydraulic cylinders 4″ diameter. Rolls open up to 1″ clear for easy threading.
-2 exit feed rolls, upper and lower roll driven, grip the strip to drive material thru straightener without resetting. Upper roll is lifted/lowered by 2 hydraulic cylinders 4″ diameter.
-entry ramp rolls support material to ensure smooth flow into straightener.
-hardened vertical side guide rolls align the strip to the tooling. Rolls are supported on steel slides and locked into position individually.
-The rolls are driven by a Servo-gearmotors.
-Centralized automatic lubrication system for the cradle, straightener and feeder rolls.
– The machine is supported by worm screw jacks. The jack feet act as levelling pads and rest on bars attached to the floor, or side shift frame.
2 guide posts mounted to the front mount plate prevent side movement.
Drives cabinet: Main disconnect, contactors, fusing, controls and drives.
Machine mounted operator station:
Control switches, and Touch screen HMI for Length, speed, and parameter inputs.
AutoStart, AutoStop, Feed Index, JogREV, JogFWD, Mode Select, Front shift Left/Right, Rear Left/Right
Optional Pilot release of straightener rolls. (at 40 spm requires 60deg pilot angle)
The upper rolls frame is connected by 2 shafts with eccentric pivots to ensure accurate holding of the roll position. The shafts are rotated by a servomotor. Pilot release timing is controlled by press camswitch.
