MECON  30,000 lb. Capacity x 48” Width Coil Handling System

Proposed Solution:

Coil car model 300cc with powered top rolls.

  • 30,000LBS capacity
  • A coil car with power lift of 20″, 110” travel, hydraulic system common to uncoiler.
  • Dual scissor stabilizer to support top of car when loaded off center.

Uncoiler model 300btj48 with optional side shift.

  • Single spindle uncoiler, with threading / rewinding drive, and air brake.
  • 4 segment mandrel with ramp style hydraulic expansion.
  • Uncoiler side shift, 18″ of travel.  The uncoiler is mounted on bronze bearings and is shifted sideways by a hydraulic cylinder for easy alignment of the coil to the process.  Uncoiler may be shifted during processing or loading.
  • The mandrel is 4 segments, with wedge style expansion and is hydraulically expanded/retracted.  Id range 19″ to 24.5″, O.D. max. 60″ with coil car (optional 72″max O.D.)

Heavy Duty HD48 Threading – Coil over arm with power wheel. Peeler / coil breaker.

  • The over arm clamps onto the coil to contain the coil end when the straps are cut.
  • The wheel is powered by a hydraulic motor and drives the coil to thread the start of the coil to the input pinch rolls of the straightener.
  • The coil breaker lifts to press the strip against a flattening block on over arm and thus de-kink the start of the strip.  This allows easy threading of steel into straightener.

Powered Straightener model 5-4str48bu

  • 11 hardened and ground rolls running on precision needle bearings,
  • 2 entrance pinch rolls, 5.000″ diameter, close onto material to drive starting edge thru straightener, not required to change straightener settings for threading,
  • 2 exit pinch rolls, 5.000″ diameter, open for threading, close for running,
  • 7 straightening rolls, 4.000″ diameter, 4 lower rolls all driven, 3 upper rolls idle,
  • Individual power adjust upper rolls, position shown on .001″ graduation counters.
  • Straightener drive. Variable Frequency AC Motor control with AC induction motor.
  • Speed 0-60 fpm. Infinitely variable.
  • These drive systems give very smooth acceleration and deceleration with no sudden shocks to the material or drive components, and thus extend machine life and limit material marking.
  • The drive system will be upgraded to 30 hp (to support the required feed/SPM requirement) to match the capacity of the straightener and the 30,000 lbs. coil.  Material guidance
  • Coil peeler and breaker guide material into straightener.
  • Entrance vertical guide rolls to track the material.
  • Exit ramp rolls support strip as it exits straightener and drops into loop.

Requirement: Cut to length system

Material: 16-26GA steel
Coil Weight:  20,000lb coils
Width Material: 28 ½” to 54″
Cut lengths:  6 ¼ to 82 1/2”
Floor space: 55ft
Coil loading beside uncoiler

Important Considerations:
Tight tolerance on length.
Out of square causes problems
Flatness
Rewinding of partial coils
Coil Handling streamline and automate
Stacking system, even stacking very important
Minimize marking.
