Cut to Length Line (Cross Cutting Machine)

Description
Cut to length production line is made up of coil car, decoiler, entry support device, width adjustor device, leveling machine, gauge table, shearing machine, run out table, pneumatic discharge and stacker device, unloading table, pneumatic system, electrical system with computer PLC program control and hydraulic system. The rolling plate is unfolded and leveled. Then it is sized and sheared into the needed flat plate with a certain length.

Application
Cut to length production line is used for uncoiling, straightening, gauging, and crosscutting to length and stacking work. Cross cutting machine is widely used in cold or hot rolling carbon steel, tinplate, and all the other kinds of metal materials with surface coating.

Features
1. Cross cutting machine is controlled by PLC system or manually as required by the customer. It has PLC controlled single shaft feeder; the information of length, shearing numbers and speed can be input to the HMI (human machine interface).

2. When the needed shearing number is reached the cut to length production line can stop automatically.

3. The production speed can be adjusted. It has a gauge with high precision, and the whole line can work automatically and operate easily thereby producing smooth sheets.

Production Process of Cut to Length Production Line
Loading Coil → Uncoiling → Leveling → Edge Cutting → Looping → Precision Leveling → Sizing and Cutting off → Connecting in Certain Number → Connection
