Description
Technical field
The present invention relates to a kind of stainless steel annealing pickling line, specifically refer to its brushing device inlet/outlet place band steel curvature correcting device.
Background technology
On hot-rolled stainless steel annealing and pickling line, the band steel of coming from hot rolling workshop is general all with certain curvature, raise up in the middle part of steel plate, the band steel of thinner thickness, generally can correct its convexity by the pressure of brush roll, band steel is flattened, can normally scrub, but for the curvature of the thicker band steel band of thickness, can not correct with the pressure of scrubbing roller, this curvature will make brushing device not scrub normally, make the wearing and tearing that brush roll is uneven, be easy to damage brush roll, as shown in Figure 1, brush roll 32 will be caused at band steel 33 intermediate raised portion and steel edge portion, the wearing part 31 excessively of lower brush roll 34 bristle 35, 36, the words of producing in these cases, in a short period of time, brush roll will be caused can not to continue to use, greatly reduce the service life of brush roll.
Summary of the invention
In view of this, the technical problem to be solved in the present invention is the band steel curvature correcting device providing a kind of brushing device inlet/outlet place, can correct the curvature of thickness compared with heavy gauge steel strip, brush roll is worn and torn more uniformly, effectively increase brush roll service life, reduce production cost.
For solving the problems of the technologies described above, technical scheme of the present invention is achieved in that a kind of band steel curvature correcting device of brushing device inlet/outlet place, comprises the top backing up roll of support belt steel, corrects lower correction roller and the hydraulic cylinder of the curvature of band steel; This top backing up roll, lower correction roller lay respectively at the upper and lower both sides of band steel; Hydraulic cylinder is provided with the displacement transducer recording its displacement, and top backing up roll, lower correction roller are separately fixed on upper backup roll base and lower correction roller base; This hydraulic cylinder is connected with lower correction roller base with upper backup roll base with rotating shaft respectively by swinging slide bar, stretching for the distance adjusting backing roll and correct between roller by hydraulic cylinder.
Further, described top backing up roll is arranged on band steel convex surface curvature side, corrects roller and is arranged on band steel concave surface curvature side.
Further, described top backing up roll roll surface scribbles rubber.
Further, described lower correction roller is provided with two, and symmetrical placement that form an angle mutually.
Further, described top backing up roll, lower correction roller strap have certain convexity, and pars intermedia is outwardly relative to both ends.
The technique effect that the present invention reaches is as follows: the band steel curvature correcting device at brushing device inlet/outlet place of the present invention, can correct the curvature of thickness compared with heavy gauge steel strip, brush roll is worn and torn more uniformly, effectively increases brush roll service life, reduces production cost.Further, top backing up roll, lower correction roller strap have certain convexity, and pars intermedia is outwardly relative to both ends.Lower correction roller is provided with two, and symmetrical placement that form an angle mutually, can reduce band steel widely due to curvature to reduce, and steel edge portion is to resistance during two lateral movements.The convexity of top backing up roll makes band steel make contact to linear contact lay, scratches belt steel surface.

Detailed description of the invention
As shown in Figure 2, the band steel curvature correcting device at brushing device inlet/outlet place, comprise hydraulic cylinder 5, displacement transducer 2, top backing up roll 15, lower correction roller 17, top backing up roll swings slide bar 4 and lower correction roller swings slide bar 6, displacement transducer 2 to be fixed on hydraulic cylinder 5, hydraulic cylinder 5 is connected with top backing up roll and swings slide bar 4, lower correction roller swings slide bar 6, top backing up roll swings slide bar 4, lower correction roller swings slide bar 6 respectively by connecting pin 1, 9 are connected on upper backup roll base rotating shaft 12 and lower correction roller base rotating shaft 19, upper backup roll base rotating shaft 12 and lower correction roller base rotating shaft 19 respectively with upper backup roll base 14, lower correction roller base 20 is connected, upper backup roll base 14, lower correction roller base 20 is connected by supporting roller bearing seat 13, lower correction roll bearing seat 18 is connected top backing up roll 15, lower correction roller 17.
Wherein, the hydraulic stem of hydraulic cylinder 5 is swung slide bar 6 with lower correction roller be slidably connected by lower correction roller swing sliding bar pin 7, slide rail 8, the cylinder body of hydraulic cylinder 5 swings sliding bar pin 11, slide rail 3 and top backing up roll by upper backup roll and swings slide bar 4, by above-mentioned connection, hydraulic cylinder 5 is for adjusting the distance between top backing up roll 15 and lower correction roller 17, displacement transducer 2 is for recording hydraulic cylinder 5 displacement, and upper backup roll 15 is for support belt steel 16, and lower correction roller 17 is for correcting band steel curvature.
Lower correction roller 17 is arranged on band steel 16 concave surface curvature side, top backing up roll 15 is arranged on band steel convex surface curvature side, wherein lower correction roller 17 and top backing up roll 15 roll surface are all with certain convexity, top backing up roll 15 is made with certain convexity, when being to prevent lower correction roller 17 from correcting band steel curvature, top backing up roll 15 makes contact to linear contact lay with band steel 16, and scratch belt steel surface, top backing up roll 15 roll surface scribbles certain thickness rubber; Lower correction roller 17 is also all with certain convexity, and correct roller 17 symmetrical placement at an angle for twice, can reduce band steel 16 widely due to curvature reduction, band steel 16 edge is to resistance during two lateral movements.
As shown in Figure 3, the use principle of this device is: first need the band steel 41 according to different in width, be that band steel flattens not with width during curvature with this width of steel 42() and thickness, calculate the roll gap amount needing adjustment, the computational methods of the roll gap amount of needs adjustment are: by identical with thickness (thinner thickness), the adjustment roll gap amount corresponding to band steel demarcation different in width band steel that width is different, then a curved line relation formula is gone out according to the actual data regression recorded, according to this relational expression during actual production, input strip width, the adjustment roll gap amount calculated deducts belt steel thickness and is the roll gap amount needing adjustment.
When incoming band steel is more open and more flat, thinner thickness, when curvature is less, operating personnel are set to off-line state this band steel curvature correcting device of the present invention, and top backing up roll 15 and lower correction roller 17 are full open position, apart from maximum.The uneven wear of the brush roll caused due to band steel curvature can be reduced by the present invention widely, thus extend brush roll service life, reduce production cost.
The above, be only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.
