Embodiment

Particular content of the present utility model and its course of work are illustrated below in conjunction with the accompanying drawings.

The forward and reverse repeatedly rolling device of the four-roller is mainly by the 1a of lower roll I, the 1b of lower roll II, upper roller 2a, upper roller 2b and support 3 And two upper roller support bases 5 form, the described 1a of lower roll I, the 1b of lower roll II are connected with support 3, can synchronously be turned forward or backwards Dynamic, the upper roller 2b positioned at the 1a of lower roll I, the upper roller 2a of the 1b middle upper parts of lower roll II and side connects with two upper roller support bases 5 respectively Connect, two upper roller support bases 5 realize independent movement up and down by elevating mechanism, and upper roller 2a can active rotation.Elevating mechanism can be with It is hydraulic mechanism or mechanical mechanism；Two lower roll gears of a gear and parameter identical of synchronous rotary mechanism 4 engage simultaneously, Make the 1a of lower roll I, the 1b synchronous axial systems of lower roll II, upper roller 2a has independent rotating mechanism 6 so as to active rotation.

Fig. 1 is apparatus structure schematic diagram, and device is mainly by parts such as support, two lower rolls, two upper rollers, upper roller support bases Form；

Fig. 2 is that sheet material positions schematic diagram before roll-in starts, between sheet material is put into the up-down rollers of device, among two lower rolls The upper roller of top is pushed clamping sheet material and it is positioned using side upper roller；

Fig. 3 is positive roll-in schematic diagram, and sheet material is carried out just using two lower rolls and positioned at the upper roller of two lower roll middle upper parts To rolling formation, radius is less than radius of target after roll-in；

Fig. 4 is reverse roll-in schematic diagram, and the upper roller positioned at two lower roll middle upper parts rises, and side upper roller declines, and utilizes two Upper roller and the lower roll below two upper rollers centre carry out reverse rolling formation to sheet material, and radius is more than radius of target after roll-in.

The course of work of forward and reverse repeatedly rolling device is exemplified below.

Sheet material is put into forward and reverse repeatedly in rolling device, uses two lower rolls and upper in two lower roll middle upper parts Roller clamps sheet material, 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, rise the upper roller of two lower roll middle upper parts, using two upper rollers and The lower roll of lower section depresses sheet material among two upper rollers, reverse 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.Judge whether to need to continue roll-in according to the size of sheet material and performance, 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 are less than the radius of target of workpiece, but more than the radius after last positive roll-in；Descending profile again Upper roller height, rise the upper roller of two lower roll middle upper parts, use two upper rollers and the lower roll below two upper rollers centres 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, decline the upper roller pressure sheet material of two lower roll middle upper parts, direct roll-in to target half Footpath, terminate roll-in.
