3)       And placed ahead of working stations for performing Angle Steels fabrication, and J16 Angle Stiffener Steel Plate Straightening Machine;

4)       Wuxi JACK tailor made JF16 Sheet Metal Steel Plate Straightening Machine in test run before painting: (Fig.8)

5)       Workpiece Size: The max. size of sheet metal to be processed in this JF16 Steel Plate Straightening Machine is: 3200mm width/ 16mm thickness and 30m length;

2.       Structure of and Operation on JF16 Sheet Metal Steel Structure Straightening Machine:

1)       Straightening Roller Quantity in Sheet Metal Steel Plate Straightening Machine:

a)       There is one piece of straightening unit in one set of the Steel Plate Sheet Metal Straightening Machine;

b)       The straightening unit can be moved leftward and rightward under motor drive, for aiming on joint welding seam precisely;

2)       Operation on JF16 Steel Plate Sheet Metal Straightening Machine is relatively simple: There is a hand held operating pendant equipped with the machine, shown as below:

Operating pendant of Wuxi JACK JF16 Sheet Metal Steel Plate Straightening Machine: (Fig.9)

3)       Working Unit and Workpiece Protection in JF16 Steel Plate Sheet Metal Straightening Machine:

a)       The motorized supporting rollers can be elevated up and down within certain stroke (Here in JF16 is 40mm);

b)       The downward acting straightening roller can also descend down and ascend up under motor drive;

c)       In this way, the straightening roller and supporting rollers can be “moved away” during workpiece feeding into and out of the Steel Plate Straightening Machine, avoiding the hidden risks of bumping/ collision/ scratch.
