The course of work of forward and reverse multiple rolling device is exemplified below.
Sheet material is put into forward and reverse multiple rolling device, it is upper using two lower rolls and in two lower roll middle upper parts
Roller clamps sheet material, and the upper roller height of descending profile conveys the upper roller of sheet material top to side, positions sheet material.Rise the upper roller of side
Highly, decline the upper roller pressure sheet material of two lower roll middle upper parts, positive roll-in for the first time is carried out to sheet material, radius is small after roll-in
In the radius of target of workpiece.The upper roller height of descending profile, rises the upper roller of two lower roll middle upper parts, using two upper rollers and
Lower roll below in the middle of two upper rollers depresses sheet material, reversely roll-in for the first time is carried out to sheet material, radius is more than work after roll-in
The radius of target of part.Judged whether to need to continue roll-in according to the size and performance of sheet material, continue forward and reverse roll-in if desired,
Then rise the upper roller height of side, decline the upper roller pressure sheet material of two lower roll middle upper parts, sheet material is carried out next time positive
Roll-in, its roll-in radius is less than the radius of target of workpiece, but more than the radius after last positive roll-in；Descending profile again
Upper roller height, rises the upper roller of two lower roll middle upper parts, using two upper rollers and in the middle of two upper rollers below lower roll
Sheet material is depressed, reverse roll-in next time is carried out to sheet material, its roll-in radius is more than the radius of target of workpiece, but anti-less than last
To the radius after roll-in, repeatedly forward and reverse roll-in is so carried out until workpiece radius is close to radius of target.Terminate roller if desired
Pressure, then rise the upper roller height of side, declines the upper roller pressure sheet material of two lower roll middle upper parts, direct roll-in to target half
Footpath, terminates roll-in.
