Abstract
The utility model discloses an opening and closing mechanism of a straightening rack. The opening and closing mechanism of the straightening rack comprises an upper rack and a lower rack. An upper straightening roller system and a rectification roller are arranged in the upper rack. Three sets of lower straightening roller systems which correspond to the upper straightening roller system and the rectification roller are arranged in the lower rack. An elevation mechanism which can drive the three sets of the lower straightening roller systems to move vertically are arranged in the lower rack. An oil cylinder is arranged on the lower rack. The oil cylinder drives the upper rack to move vertically and corresponds to the lower rack. The oil cylinder drives the upper rack to move vertically and corresponds to the lower rack which is parallel to the upper rack in motion. When a straightening unit works, if the upper rack swings in a deflected mode, the straightening rollers and the rectification roller can slide on the surface of a strip and cause scrapes on the strip. The opening and closing mechanism of the straightening rack can eradicate the scrapes. Surface quality of the strip is improved, the straightening unit can work normally, continuous tension leveling of the strip can be achieved and use capability of equipment is improved.
Description
Technical field
The utility model relates to the finishing equipment in a kind of aluminium process equipment, specifically the curved strong frame open-and-close mechanism in a kind of stretch bending-straightening machine.
Background technology
The structure of aligning frame in the existing stretch bending-straightening machine, generally comprise the upper straightening roll system, column and the rectification roll that are fixed on the upper spider, also comprise the lower replaceable straightening roller system that is fixed on the lower bearing bracket, upper spider and lower bearing bracket are to carry out the folding operation by the jointed shaft that is arranged on frame one side with the oil cylinder that is positioned at the jointed shaft opposite side; When upper spider is opened, three groups of replaceable straightening roller systems on the lower bearing bracket drop on lowest order by elevating mechanism, carry out the threading operation, or do not use curved strong roller work, only carry out the pure extension operation; When curved strong working, after threading finishes, start oil cylinder upper spider is pulled to horizontal position, the column that is fixed on the upper spider has been pressed on the lower bearing bracket, at this moment, the working roll of the replaceable straightening roller system in the upper spider and the lower roll surface of rectification roll are just in time in the position of machine alignment, replaceable straightening roller system on the lower bearing bracket according to technological requirement, rises to respectively the travel position of requirement by elevating mechanism, strip is carried out the stretch bending finishing, adopt such equipment can realize that strip carries out the stretch bending finishing work.
But because upper lower bearing bracket is by the hinge folding, for smooth folding frame, matched in clearance is all adopted in hinge and its hole that matches, this gap is by the amplification of the radius of gyration, the upper spider that oil cylinder is left behind still can be in the middle of work, produce a certain amount of up and down ripple pendulum, smoothing roll scratches in the wiping of strip surface.For example, hinge is the minimum 0.01mm of being of the fit clearance δ of ф 70 H7/g6, be 0.059mm to the maximum, when oscillating oil cylinder reaches total travel 310mm, upper spider 1 clockwise angle of oscillation β=11 degree, as calculated, the hinge fit clearance is under the amplification of radius of gyration R=1570mm, the hinge other end upper spider pulling cylinder bracket deviation △ of place can reach 3mm ~ 17.7mm, although be fixed on the cambered surface that column lower surface on the upper spider has been processed into R365, the deviation that adapts to upper spider swings, but it can't eliminate the replaceable straightening roller system that is fixed on the upper spider and rectification roll when the upper spider beat, slip on strip surface, thus cause the wiping on the plate face to scratch, have a strong impact on plate face quality.For this reason, the curved strong unit in the stretch bending-straightening machine is mostly on the shelf at present, only as a kind of pure extension equipment for straightening usefulness, has greatly wasted device resource.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of smoothing roll scratches problem in the wiping of strip surface curved strong frame open-and-close mechanism that solves.
In order to solve the problems of the technologies described above, curved strong frame open-and-close mechanism of the present utility model comprises upper spider and lower bearing bracket, is provided with upper straightening roll system and rectification roll in the upper spider; Be provided with replaceable straightening roller system under three groups corresponding with upper straightening roll system and rectification roll in the lower bearing bracket, also be provided with in the lower bearing bracket and can drive the elevating mechanism that replaceable straightening roller system moves down in the vertical direction under three groups; Oil cylinder is installed on the lower bearing bracket, and the hydraulic oil cylinder driving upper spider is lower mobile in the vertical direction with respect to lower bearing bracket.
The left and right sides of described upper spider is provided with guide pillar simultaneously; Be installed with the fairlead that can make guide pillar keep vertical direction to move on the described lower bearing bracket.
After adopting above-mentioned structure, upper spider is moved up and down with respect to lower bearing bracket is parallel; When effectively having effected a radical cure curved strong unit and having devoted oneself to work, the wiping that the curved strong roller that the beat of upper spider causes and rectification roll produce in the slip of strip surface scratches, improve surface quality of strips, thereby can allow curved strong unit normally devote oneself to work, the real continuously elongated bending straightening of realizing band, the use ability of raising equipment.
Description of drawings
Fig. 1 is the structural representation of the curved strong frame open-and-close mechanism of the utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, curved strong frame open-and-close mechanism of the present utility model is described in further detail.
As shown in the figure, curved strong frame open-and-close mechanism of the present utility model comprises upper spider 1 and lower bearing bracket 2, is provided with upper straightening roll in the upper spider 1 and is 3 and rectification roll 4; Be provided with in the lower bearing bracket 2 with upper straightening roll be 3 and corresponding three groups of rectification roll 4 under replaceable straightening roller system 5, also be provided with in the lower bearing bracket 2 and can drive under three groups in the vertical direction lower mobile elevating mechanism 6 of replaceable straightening roller system 5; Oil cylinder 9 is installed on the lower bearing bracket, and it is lower mobile in the vertical direction with respect to lower bearing bracket 2 that oil cylinder 9 drives upper spider 1.The left and right sides of upper spider 1 is provided with guide pillar 7 simultaneously; Be installed with the fairlead 8 that can make guide pillar 7 keep vertical direction to move on the lower bearing bracket 2.
