Straightening Machine for Sheet Metal

説明

 

 

The machine’s main processes include:

 

Unwinding and Feeding

 

The included decoiler ensures smooth and automatic unwinding.

 

Leveling

 

Multiple staggered leveling rollers are used. Normally 9 rollers (4 upper rollers and 5 down rollers) are used to process 2.0mm thick sheets, while 13 rollers (6 upper rollers and 7 down rollers) are used for sheets 2.5-3.0mm thick coils. Repeated straightening can eliminate internal stresses and unevenness, then get a perfectly flat sheet suitable for subsequent precision processing or direct use. All rollers are made from Cr12 mould steel and fine processed to make sure long life and leveling effect.

 

 

Slitting

 

After the sheet is leveled, it passes through a slitting head equipped with multiple pairs of circular blades (upper and down). These blades can slit the wide coil into several narrow strips of the desired width, based on the set width. For example, a 1-meter-wide steel coil can be slit into five 20-centimeter-wide strips.

 

 

Shearing

 

After slitting (or without slitting), the flat sheet (or strip) is conveyed to the cut-to-length mechanism. When the material length reaches the set length, the machine will do automatically shearing. For example, a continuous steel strip can be cut into rectangular sheets measuring 1000mm x 200mm.
