Present invention aims at a kind of forward and reverse multiple rolling device of five rollers of offer, when eliminating or significantly reducing unidirectional roll-in
Inside workpiece residual-stress value, reduce workpiece resilience.The device is put into sheet material according to the size and performance parameter of sheet material
Multiple roll-in between the up-down rollers of forward and reverse multiple rolling device, first makes workpiece bows radius be less than radius of target, then makes work
Part bending radius is more than radius of target, then is moved closer to by required roll-in number of times to radius of target, required for being finally reached
Radius of target.
The above-mentioned purpose of the present invention is achieved through the following technical solutions：
The forward and reverse multiple rolling device of five rollers of the present invention is main by two lower rolls 1a and 1b, middle upper roller 2, side upper roller 3a
And 3b, support 6, middle upper roller support base 4, side upper roller support base 5 are constituted, it is characterised in that two described lower rolls 1a and 1b
It is connected with support 6, synchronous axial system forward or backwards can be realized by lazy-tongs 7；Middle upper roller 2 is located at two lower roll 1a and 1b
Middle upper part, is connected with middle upper roller support base 4, is lifted by elevating mechanism；Both sides upper roller 3a and 3b is supported with side upper roller
Seat 5 is connected, and passes through elevating mechanism synchronization lifting.
The elevating mechanism of the present invention is screw mechanism or hydraulic mechanism.
Two lower roll gears of a gear and parameter identical of the synchronous rotary mechanism 7 of the present invention are engaged simultaneously, make two
Individual lower roll synchronous axial system.
Technique effect：The forward and reverse multiple rolling device of five rollers of the present invention, compared with traditional unidirectional rolling equipment, by many
Secondary forward and reverse alternately roll-in, can eliminate or significantly reduce inside workpiece residual stress, reduce the resilience of workpiece, especially protect
Demonstrate,prove with the machining accuracy after the mechanical milling of muscle integral wall plate-type work or milling.

Embodiment
Particular content of the present invention and the course of work are illustrated below in conjunction with the accompanying drawings.
The forward and reverse multiple rolling device of five rollers is main by the 1a of the lower roll I and 1b of lower roll II, middle upper roller 2, the 3a of side upper roller I
And the 3b of side upper roller II, support 6, middle upper roller support base 4, side upper roller support base 5 are constituted, the described 1a of lower roll I and the 1b of lower roll II
It is connected with lower roller support 6, synchronous axial system forward or backwards can be realized by lower roll synchronous drive mechanism 7；Under middle upper roller 2 is located at
The 1a of roller I and the 1b middle upper parts of lower roll II, are connected with middle upper roller support base 4, are lifted by elevating mechanism；The 3a of side upper roller I and side
The 3b of upper roller II is connected with side upper roller support base 5, passes through elevating mechanism synchronization lifting；One of lower roll Synchronous Transmission rotating mechanism 7
Two lower roll gears of gear and parameter identical are engaged simultaneously, make two lower roll synchronous axial systems.
Fig. 1 is apparatus structure schematic diagram, and device is mainly by lower roll, middle upper roller, side upper roller, support, intermediate calender rolls support base
And the part such as side upper roller support base is constituted；
Fig. 2 is apparatus structure front view；
Fig. 3 is sheet material positioning schematic diagram before roll-in starts, and utilizes a side upper roller, middle upper roller and a lower roll fixed plate
Material, sheet material is positioned by another side upper roller；
Fig. 4 is positive roll-in schematic diagram, and positive roll-in is carried out using the upper roller of two lower rolls and two lower roll middle upper parts；
