It can be realized by lazy-tongs 7 and be rotated synchronously forward or backwards；Intermediate upper roller 2 is located at two lower roll 1a and 1b middle upper parts, with
Intermediate upper roller support base 4 connects, and is lifted by elevating mechanism；Both sides upper roller 3a and 3b is connect with side upper roller support base 5, is passed through
Elevating mechanism synchronization lifting.
The elevating mechanism of the present invention is screw mechanism or hydraulic mechanism.
A gear two lower roll gears identical with parameter of the synchronous rotary mechanism 7 of the present invention engage simultaneously, make two
A lower roll rotates synchronously.
It is as follows using the device shaped sheet technique：
Make plate between up-down rollers, using a side upper roller, intermediate upper roller and a lower roll fixed plate, by another
One side upper roller positions plank；
Upper roller among lower roll is pushed, both sides upper roller is made to rise, carries out positive rolling formation, roll-in radius is small
In target shape radius；
Upper roller among lower roll is risen, so that both sides upper roller is pushed, carries out reversed rolling formation, roll-in radius is big
In target shape radius；
If you need to continue, the upper roller of the left and right sides is made to rise, is located at the upper roller among two lower rolls and pushes, carry out forward direction and be rolled into
Shape makes its roll-in radius be less than target shape radius, but more than last positive roll-in radius；
It again rises the upper roller among two lower rolls, so that both sides upper roller is pushed, carry out reversed rolling formation, make its roll-in radius
More than target shape radius, but less than last reversed roll-in radius；
Forward and reverse roll-in is repeated, workpiece radius is made to move closer to radius of target；If you need to stop roll-in, make to be located in two lower rolls
Between upper roller push, so that the upper roller of the left and right sides is risen, carry out positive roll-in, direct roll-in to target shape radius.
Technique effect：The forward and reverse multiple rolling device of five rollers of the present invention, compared with traditional unidirectional rolling equipment, by more
Secondary forward and reverse alternately roll-in, can eliminate or significantly reduce inside workpiece residual stress, reduce the rebound of workpiece, especially protect
Card is with the machining accuracy after the plate-type work machinery milling of muscle integral wall or milling.
