Cut to Length Line Machine
CUT TO LENGTH LINES – FOR CR COILS /HR COILS
A cut to length line is generally used for jobs like uncoiling, straightening, measuring rolls, cross cutting to length and stacking of various metal such as Cold/Hot rolling coils, Stainless steel coils, Tin Plate coils, PPGI/GP/Alumunium coils.
FEATURES OF CUT TO LENGTH LINE :
- Our cut to length line uses roll feeding, AC servo drive/AC drive.
- It has full length NC control system that ensures fast positioning.
- It has a hard chrome plated surface and is durable and abrasion resistant for special coils material.
- It is used together with a hydraulic shear/Pneumatic clutch shear machine to carry out fast shearing and convenient clearance adjustment.
- Our cut to length line is suitable for hot rolling carbon steel, cold rolling carbon steel, tin plate coils, stainless steel coils and other kind of metals with coated surface.
SPECIFICATIONS & FEATURES
- We are manufacturer CTL lines from 750/1250/ 1650/2000/2500 mm coil width.
- Thickness of coils are varies from 0.20-3.00/6/8/12/ 16/20/25 mm of CRC, HR, Aluminium & SS material.
- Coil weight varies from 10/25/30/40 MT.
- Shearing machine are available both type. (Pneumatic clutch operated, Hydraulic & Servo Motor drive).
- Straightener/leveller machine rollers are made of alloy steels driven by gears and auxiliary gear box.
- Line speed from 25-100 meter per minute.
- Variable speed controlled lines.
- Encoder with PLC control base line-optional.
- NC servo motor high speed control line.
- Back tray, motorised conveyer or hydraulic stacker – optional.
- Flying Shear.
DETAILS OF CUT TO LENGTH LINE MACHINES
Coil Car with Saddle
Coil Car/ Lifter ease the work of loading the coil on De-coiler’s Jaws by coinciding the axis of both. Coil Car is power driven and can move to & fro the De-coiler on rails. Coil Car & Coil Lifter both can move up/down by hydraulic cylinder.
De-coiler/Un-coiler Unit
The de-coiler/uncoiling unit of our cut to length line allows several coil stocks to be pre-placed on the loading station. It is available with single head or double heads to suit different requirements.
Sheet Leveller
The leveller of our cut to length line may have various designs, from 4HI/6HI. The rolls can be adjusted manually, hydraulically or by motor. Roll is hardened to HRC 55-60. It provides good abrasion resistance and long service life.
Snubber & Pillar Table Assembly
Snubber is used for pressing the coil O.D. Snubber can be operated either hydraulically or pneumatically. Hydraulically operated pillar table facilitates the entry of sheet into straightener.
NC Servo Roll Feeder / Encoder
our cut to length line uses a pair of feed rolls, driven by an AC servo motor/AC drive, to feed the sheet precisely according to the set length.
They ensure fast positioning with higher accuracy. The rolls are adjusted by pneumatic cylinders. In case of tight line, the length measurement is done by encoder assembly.
Shearing Unit
It cuts the coil into sheets of desired length. We provide a range of shearing machine both mechanically & hydraulically operated. For higher stroke, pneumatic clutch is also provided with mechanical shearing machine.
Conveyor Unit
Conveyor unit is used to carry out the sheet, after that sheet goes to stacker unit for stacking.
Stacking Unit
Our cut to length line can be equipped with a pneumatic or electromagnetic stacking unit. It is equipped with a blower to protect the surface from scraping. Both longitudinal and transverse stacking are available.
Loop Table
Application:
Loop System Is Incorporated In Between 2 Line Equipment To Synchronize Line Speed Or Some Time To Avoid Tension Or Stretch On Material Being Processed.
Construction:
1. Steering Rolls Quad Table on Both Entry & Exit of Loop to Guide the Processing Material.
2. Loop Closing Table to Close the Loop pit for Entry of New Coil End.
3. Loop of sheet controlled from operator desk.
