Description
Technical field
The present invention relates to be specially adapted for the control appliance that utilizes roll bending or the method for rolling mill for metal or its converted products, be used for the rolling of non-ferrous metal and alloy thin band.
Background technology
The work roll bending device of traditional six-high cluster mill, up-down rollers is provided with separately, and because of structural limitations, the inlet of each working roll bearing block or outlet need to arrange two hydraulic cylinders arranged side by side, as depicted in figs. 1 and 2.Every rolling mill need be installed 16 positive and negative roller cylinders, and pipeline is various, and maintenance is difficulty very.
Summary of the invention
Proposition of the present invention is intended to design the positive and negative roll-bending device of a kind of combined type based on six-high cluster mill, to reduce the influence of pipeline seepage to mill roll bending power, reduces the maintenance capacity of rolling mill hydraulic pipeline simultaneously.
Technical solution of the present invention is achieved in that
The positive and negative roll-bending device of a kind of combined type based on six-high cluster mill, constitute by 4 roller cylinders, described roller cylinder is contained in respectively between the upper working rolls and lower working rolls bearing block at fore side and transmission side entrance and exit place, the structure of 4 roller cylinders is identical, by top board, cylinder cap, fixed block, cylinder body, piston rod, ball ring, connecting rod, feather key, retaining ring, composite cylinder jacket and lower platen are formed, it is characterized in that: fixed block is fixed on the waist piece at window middle part of memorial archway, cylinder body is housed in the fixed block, its upper end connects cylinder cap, cylinder cap connects top board, and top board is contained in the T-slot of top working roll bearing block; Necking down is arranged at the bottom of cylinder body, suit composite cylinder jacket on it, and the bottom of composite cylinder jacket connects lower platen, and lower platen stretches in the T-slot of bottom working roll bearing block; Cylinder body and cylinder cap, piston rod are formed the roller hydraulic cylinder, and its plunger shaft has logical hydraulic fluid port; Piston rod also links into an integrated entity by ball ring, connecting rod, feather key and retaining ring and composite cylinder jacket, forms compound roller hydraulic cylinder, and logical hydraulic fluid port is arranged on its rod end chamber, and compound roller hydraulic cylinder moves with piston rod, and slides up and down along cylinder body; During the plunger shaft fuel feeding, hydraulic cylinder is two-way to be stretched out, and top board upwards compresses the top working roll bearing block, and lower platen compresses the bottom working roll bearing block downwards simultaneously, produces positive bending roller force, makes the distortion of upper working rolls and lower working rolls convex; During the rod end chamber fuel feeding, the two-way contraction of hydraulic cylinder, top board is strained the top working roll bearing block downwards, and lower platen is upwards strained the bottom working roll bearing block simultaneously, produces negative bending roller force, makes the distortion of upper working rolls and lower working rolls spill.
Between described fixed block and the composite cylinder jacket feather key is housed.
Described compound roller hydraulic cylinder is contained in the center hole of fixed block, can slide with the endoporus of cylinder body along fixed block when flexible.
Compared with prior art, advantage of the present invention is apparent, mainly shows:
1 hydraulic cylinder quantity is few, and pipeline quantity is few, is difficult for taking place seepage, and it is stable that bending roller force is easy to keep;
2 is simple and compact for structure, do not influence memorial archway rigidity;
3 maintenance capacities are little, and roll change is convenient;
Bending roller force equal and opposite in direction about in the of 4, direction is opposite, memorial archway is not produced additional force.

The specific embodiment
As Fig. 3～positive and negative roll-bending device of a kind of combined type shown in Figure 6 based on six-high cluster mill, constitute by four roller cylinders, be installed in respectively between the upper working rolls and lower working rolls bearing block at entrance and exit place of fore side and transmission side, four part-structures are basic identical, each roller cylinder is mainly by top board 1, cylinder cap 2, fixed block 3, cylinder body 4, piston rod 5, ball ring 6, connecting rod 7, feather key 8, retaining ring 9, composite cylinder jacket 10, lower platen 11 grades are partly formed, fixed block 3 usefulness bolts put together on the waist piece at window middle part of memorial archway 20, cylinder body 4, cylinder cap 2, piston rod 5 is formed the roller hydraulic cylinder, composite cylinder jacket 10 is enclosed within the cylinder body outside, and by connecting rod 7, ball ring 6 links to each other with the piston rod of retaining ring 9 with the roller cylinder, and the contact position between connecting rod 7 and piston rod 5 and the composite cylinder jacket 10 adopts ball ring 6 to carry out automatic aligning.Top board 1 is connected with cylinder cap 2 and stretches in the T-slot of top working roll bearing block 12, and lower platen 11 is connected with composite cylinder jacket 10 and stretches in the T-slot of bottom working roll bearing block 13.Compound roller hydraulic cylinder is positioned at the center hole of fixed block 3, can slide up and down along the fixed block endoporus when flexible.Between fixed block 3 and composite cylinder jacket 10, feather key 8 is set, prevents that the hydraulic cylinder rotation from limiting the flexible limit of hydraulic cylinder simultaneously.
During the plunger shaft fuel feeding, the hydraulic cylinder two-way extension, top board 1 upwards compresses top working roll bearing block 12, and lower platen 11 compresses bottom working roll bearing block 13 downwards simultaneously, produces positive bending roller force, makes the distortion of upper working rolls and lower working rolls convex.During the rod end chamber fuel feeding, the two-way contraction of hydraulic cylinder, top board 1 is tension top working roll bearing block 12 downwards, and lower platen 11 is upwards strained bottom working roll bearing block 13 simultaneously, produces negative bending roller force, makes the distortion of upper working rolls and lower working rolls spill.No matter just curved still negative curved, this acts on the bending roller force equal and opposite in direction of upper working rolls and lower working rolls bearing block simultaneously, and direction is opposite, can not produce additional force to memorial archway.
Operation principle:
During pair rolling, because the effect of roll-force, top working roll 14, bottom working roll 15 intermediate deformation are bigger, cause the band thick middle that shuts out, and both sides are thin; So during new roller grinding roller, generally roller is worn into camber, but can cause the band intermediate thin that shuts out so again, both sides are thick.
In order to solve this contradiction, adopt positive and negative roll-bending device now.Adopt negative curvedly when being new roller, the wearing and tearing back is adopted just curved.
When using new roller, generally have convexity in the middle of the roll itself, also produce hot convexity when rolling, the band intermediate thin that at this moment shuts out, both sides are thick, adopt negative roll-bending device now, make working roll forward bending in advance, working roll top working roll 14, bottom working roll 15 keep straight when rolling under the synergy of negative bending roller force and roll-force, are pressed against on intermediate calender rolls 16, the following intermediate calender rolls 17, make the thickness of strip that shuts out even, the negative bending deformation schematic diagram of roll is seen Fig. 4.After treating that roll polishes, the band thick middle that shuts out, both sides are thin, adopt positive roll-bending device this moment, make working roll back-flexing in advance, working roll keeps straight when rolling under the synergy of bending roller force and roll-force, is pressed against on the intermediate calender rolls 16, make the thickness of strip that shuts out even, the positive bending deformation schematic diagram of roll is seen Fig. 5.
