Background technology
In metal processing industry, strip straightening, as the important procedure of finishing link, is the terminal link that plate shape of finished product etc. is controlled.The straightening process of band has experienced the technical development processes such as roll straightening, tension force stretching aligning, stretch-bend leveller.Present stage, the most extensive with the use of stretch-bend leveller.Stretch-bend leveller can be realized the good aligning of band in theory.
But the restriction due to aligning unit resistance straightening unit frame for movement, has different leveling effects to different metal; For the poor supplied materials of porch plate shape, apply the technological parameter of same specification product, final leveling effect is also barely satisfactory; The lubricating oil that may use in bending straightening process, the impurity that may contain in lubricating oil or particle, easily cause pollution or blemish that strip surface is new.
Due to reason mentioned above, when the production of stretching-bending straightener group portioned product, do not drop into bending straightening unit and only use tension force stretching straightening function.In this case, owing to lacking other profile regulation means, cannot effectively correct plate shape.
Utility model content
The purpose of this utility model is to overcome the deficiency existing in the straight technology actual production of existing stretch bending sedan-chair, and a kind of variable convex tension roller system for sheet metal strip pure extension aligning is provided.
The purpose of this utility model is achieved through the following technical solutions:

The specific embodiment
Adopt variable convex jockey pulley, by the fluid pressure of the seal oil chamber between center roller and axle sleeve, control, can realize the roll surface contacting with band and there is certain convexity, thereby reach the object of the flatness defect that improves sheet metal strip.
As shown in Figure 1, sheet metal strip pure extension is variable convex tension roller system 1 for aligning, comprise at least one seal chamber 104 and hydraulic system of between axle 101, roller shell 103, roller shell 103 and axle 101, forming, the in-line 106 being connected with seal chamber 104 is connected with swivel coupling 109 through pressure transmitter device 108, the return line 105 being connected with seal chamber 104 is connected with swivel coupling 109, and swivel coupling 109 accesses to hydraulic system by pipeline; Hydraulic system comprises Hydraulic Station 111 and pressure-regulating valve group 110, and Hydraulic Station 111 is connected with pressure-regulating valve group 110 by pipeline, and pressure-regulating valve group 110 is connected with swivel coupling 109 by pipeline.Hydraulic system is input to pressure-bearing liquid in seal chamber 104, if desired, pressure-bearing liquid in seal chamber 104 also can flow back into Hydraulic Station 111 through return line 112, and roller shell 103, under the pressure-acting of pressure-bearing liquid, strain occurs, and realizes the variation of roller shell 103 surperficial convexitys.
Fluid enters into pressure-regulating valve group 110 from Hydraulic Station 111, herein, the pressure of liquid, flow etc. obtain certain control, then enter swivel coupling 109, swivel coupling 109 is mainly used in carrying fluid effect to revolving meber, the fluid that the fluid of input swivel coupling 109 is low-pressure.Pressure transmitter device increases to desired pressure value by fluid pressure, and this process is controlled.Then by pressure transmitter device 108 by the pressure setting of fluid to desired value and be transported in seal chamber 104.Roller shell 103 and clad 113 produce strain under the effect of pressurized fluid, i.e. so-called roll surface convexity.The band contacting with clad 113, under the acting in conjunction of tension force and roll surface convexity, band produces axial 100 distortion, thereby improves band 300 in the defect of this direction.
Between roller shell 103 and axle 101, be interference fit, generally the sealing of seal chamber is that interference fit by axle 101 and roller shell 103 guarantees.Leakage for preventing that variable convex tension roller system from declining and producing pressure-bearing liquid in possible stress lower seal performance, also can increase sealing device 102 if desired, and the position of sealing device 102 may be, but is not limited to the both ends of the surface of roller.
The fluid of lower pressure (not higher than 12MPa), after swivel coupling 109, is input in pressure transmitter device 108 and pressurized fluid pressure is increased and reach the pressure of expectation.Generally, pressure transmitter device 108 output end pressures become multiple or ratio to change with input pressure, and the variation of this pressure is controlled.The pressure of inputting the pressure-bearing liquid in seal chamber 104 by change makes roller shell 103 that strain occur.In the situation that some is possible, need to will be positioned at the pressurized fluid release of seal chamber, now, pressurized fluid can be back to Hydraulic Station 111 by return line 105, swivel coupling 109 and return line 112.
Sheet metal strip pure extension aligning can be used in combination by variable convex tension roller system 1, at least comprises accordingly 2 variable convex tension roller systems.
As shown in Fig. 2～4, the quantity of seal chamber 104 can be 1 or 2.The position of seal chamber can be in axial 100 optional positions.Thereby can be used for band 300 aligning of the defect of 100 diverse locations vertically.As shown in Figure 1, the defect tool that band 300 is positioned to axial 100 middle parts has a better role.As shown in Figure 4, to band 300 both sides, the defect tool at axial left side and place, right side has a better role.
Roller group 3 consists of the variable convex tension roller system with identical inner structure or different structure, as Fig. 5, by two identical variable convex tension roller systems 1, is used in combination; As Fig. 6, by four identical variable convex tension roller systems 1, be used in combination.When being used in combination, band 300 orders are through different variable convex jockey pulleys, and the actual tension force being subject to of band can increase successively or reduce successively.Based on this principle, can prevent band to be broken by unsuitable tension force.In fact, no matter which kind of is used in combination mode, and one or more variable-crown roll can replace to common cylindrical roller.
Be close within the scope of full band length the function that variable convex jockey pulley can provide tension force stretching and horizontal (strip width direction) plate shape to adjust.The plate shape that variable convex jockey pulley both can have been realized is to a certain degree adjusted, and can coordinate with miscellaneous part, system simultaneously, produces the needed tension force of deformation of strip.After variable convex jockey pulley is used in combination, the active force that band is applied can make band realize strain and plastic deformation.Reduce the dependence to bending straightening module, greatly reduced the possibility of the defects such as strip surface generation cut.The various variable convex jockey pulleys with multi-form or quantity seal chamber can be used in combination, in order to the plate shape of strip width direction diverse location is improved.Under the acting in conjunction of tension force and roll surface convexity, realize adjusting and the improvement of sheet metal strip plate shape.The large function of adjusting two of variable convex tension roller system is integrated in strip straightening tension force stretching and transverse plate shape, can random groups in real time, on-line operation.
It is to be understood that: the above is only preferred embodiment of the present utility model; for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
