3. Machine Features:
1) Pre-stressed frame structure, carried out stress annealing relief treatment after welding, with high strength, stability and rigidity.
2) With 2-way feeding and repeated leveling function.
3) The machine mainly consists of machine frame, movable crossbeam, lower crossbeam, main transmission device, work roll assembly, support roll assembly, downpress mechanism, balance device, electrical control system, and loading/unloading roller table etc.
4) Need multiple reciprocating leveling for thin plates.
5) The main machine is equipped with side vertical roller to limit the deviation of steel plate during conveying.
6) The work rolls and support rolls are all carried out surface hardening treatment and flaw detection.
7) All the roll bearings are self-aligning roller bearings.
8) With motorized roller table at feeding and discharging end.
9) With Automatic feeding and discharging roller table to facilitate the feeding and exiting of the straightening machine. The feeding roller table is equipped with a plate centering device and the rollers are powered.
11) It's suitable for the leveling of medium plate, high-precision and high strength plates.
12) Digital display, PLC control. Visual input, edit, modify and store process parameters.
13) Siemens PLC and touchscreen to control the operation.
