Description
Technical field
The present invention relates to a kind of to metallic article, especially steel band or thin plate carry out the device of leveling, this device has one first and one second smoothing roll pair, wherein the smoothing roll of each smoothing roll pair is adjacent to be provided with, the first and second smoothing roll pairs are provided with opposed to each other, to on a transport path of determining by smoothing roll, on smoothing roll, be passed through by the goods of leveling, and the intermediate space between the adjacent smoothing roll of a smoothing roll pair is provided with a smoothing roll of another smoothing roll pair opposed to each other respectively, and this device has the scaffold that is arranged on the transport path both sides, therein or by this framework smoothing roll be can be rotated to support on its end.
Background technology
By the known a kind of such device of EP 1025921 B1.In this document, use same common notion " rolling leveling " for leveling.And the notion of " leveling " is emphasized is the result of leveling process, promptly a plane, smooth goods, and the notion of " rolling leveling " it is to be noted that this process realizes by smoothing roll.These two notions are synonyms in the application's scope.
Uneven metallic article, as exist edge wave, center wave and/or vertically the metal tape of wave must carry out leveling continuing first being processed.
As shown in Figure 1, described metallic article 1 is passing through guiding on the throughput direction 19 shown in the arrow at one on the smoothing roll 2,3 on the transport path when leveling, and wherein metallic article obtains the bending of an alternation.By smoothing roll 2,3 when crooked the outer edge area of described goods 1 obtain a tension and inner peripheral area obtains a compression.When the tension of this outside greatly when surpassing elastic limit of materials, then goods are in this position extension.Be bent upwards and on its another side, produce thus tension and extension at these goods on the next smoothing roll the opposing party.One will make these goods obtain a littler extension when crooked on its curvature direction and obtain bigger extension during bending on a direction opposite with curvature in the curvature that exists in goods before the leveling.
Increase continuously and the bending of goods is reduced on throughput direction 19 continuously in the distance between the opposed smoothing roll, therefore remove curvature that in goods, exists or wave by the bending of a series of alternations.When leveling, remove curvature that in goods, exists or wave by this method by the bending of a series of alternations.
Smoothing roll according to use occasion needs varying number.Usually for thick milling material, as the thin metallic article of the leveling comparison of steel sheet-pile wall (Spundwandeisen) or rail, need smoothing roll still less when carrying out leveling as thin plate.
Described smoothing roll can be rotated to support in its end respectively inside the scaffold that is arranged on the transport path both sides or by scaffold and supports.Bearing in secondary each side of this common smoothing roll all is included in a public scaffold the inside.A leveling equipment has four scaffolds in this case: the smoothing roll pair on fore side, the smoothing roll pair on driving side, the pair of the smoothing roll below fore side and the smoothing roll pair below driving side.
Because scaffold also comprises the essential immersion mutually of smoothing roll, this scaffold is processed into the waveform (see figure 3) in its side of facing, smoothing roll can be adjusted to little spacing thus, and scaffold is leaned mutually and therefore limit lateral feeding.In the perforate that can only be provided for the smoothing roll rolling bearing certainly with smoothing roll " crest " of a size substantially the inside.
Although adopt wavy shaped configuration also can with this smoothing roll bearing, around the material thickness of the scaffold of smoothing roll axle journal and the smoothing roll axle journal that in bearing, rotates design corresponding less (see figure 4), make scaffold not exceed or only exceed slightly the diameter of rolling roller at the bearing journal place thus.If smoothing roll bearing, too thick around the material thickness or the smoothing roll axle journal of the scaffold of smoothing roll axle journal then makes scaffold and opposed scaffold collide.
But smoothing roll bearing, scaffold and smoothing roll axle journal are under the tangible mechanical load when leveling.Therefore efforts be made so that in practice these structure members have high as far as possible mechanical strength.But because above-mentioned restriction this point can not reach enough degree according to prior art, therefore the fracture of smoothing roll bearing, scaffold or smoothing roll or smoothing roll axle journal always often appears at present.
When several smoothing rolls 3 by supporting roller 4 when supporting the leveling process crooked, the situation according to prior-art devices as shown in Figure 2 is such, especially increases the danger of fracture.Can also make selectable intermediate calender rolls 5 between smoothing roll 3 and supporting roller 4, they prevent that supporting roller 4 is pressed into smoothing roll 3.Usually down smoothing roll 3 is by supporting roller 4 bendings and upper straightening roll 2 is not crooked by supporting roller 4.
External bearings must make the smoothing roll axle journal remain on and realize bending on its position simultaneously together when smoothing roll is realized above-mentioned bending.Therefore scaffold is hung swingably.Supporting force acts on the smoothing roll bearing journal when bending.Than the bearing journal of minor diameter to the crossover position of bigger aligning rolling roller since notch effect place under the bending stress.Take place especially easily because the fatigue fracture that rotoflector stress causes at this crossover position.
When the fracture of scaffold and smoothing roll takes place, must at first remove the goods that are arranged in device.For this reason usually must be under the situation of longer steel band with steel strip cutting, this is that the steel band that also causes mostly that takes a lot of trouble devalues.A band section that is arranged in device is often seriously damaged when scaffold or smoothing roll fracture, to such an extent as to this band section no longer can be used, this will produce additional cost.Have to change the scaffold of damage or the smoothing roll of fracture at last.What therefore follow the fracture of scaffold or smoothing roll is that tangible output descends and cost increases.
For fear of this point, with relatively short interval maintenance leveling equipment, wherein smoothing roll and scaffold are replaced behind given hours run in advance.Usually not only upgrade the smoothing roll of fracture under the situation of this external smoothing roll fracture, but for fear of other smoothing roll with change relevant replacing part and rupture in the near future and change all smoothing rolls at least in advance.This point produces tangible material and cost, but because other smoothing roll fracture may bring bigger defective, therefore also essential this material of tolerance and cost.
Used decades and owing to improve material progress has been arranged aspect the load of smoothing roll and its scaffold though be used for the device of leveling metallic article, smoothing roll and scaffold fracture remain distinct issues at present.
Summary of the invention
Therefore the objective of the invention is, a kind of approach be provided, how the device that is used for the leveling metallic article for above-mentioned form avoid scaffold and smoothing roll fracture and can increase service life and maintenance shop every.
This purpose is achieved thus by the device of an above-mentioned form, the scaffold of described two smoothing roll pairs on the side of transport path, be preferably on the both sides of transport path and be provided with mutually in the axial direction with staggering, at least one scaffold of a smoothing roll pair puts between the scaffold of other the mutual opposed smoothing roll pair that is arranged on the transport path both sides.
In according to device of the present invention along the scaffold of the first and second smoothing roll pairs of transport path setting like this smoothing roll axially on be misplaced mutually, they can not leaned in the hypothesis in-movement of smoothing roll pair mutually, but the side is passed through each other.Since scaffold this be misplaced space that structure uses for the external support framework no longer be subjected on perpendicular to transport path and direction perpendicular to axial direction other opposed smoothing roll pair respectively the restriction that respectively is close to scaffold.Therefore big and therefore described scaffold, smoothing roll bearing or smoothing roll axle journal can bear bigger load.
One puts between the scaffold of each other smoothing roll pair of transport path both sides perpendicular to transport path and perpendicular to this scaffold that axially extends to of transport axis always according to bigger scaffold of the present invention." put in " at this and to mean, from the side, promptly smoothing roll axially on look, it is following and upper support framework and lower support framework be we can say (with being misplaced on smoothing roll is axial) " overlap joint " that the following seamed edge of a upper support framework is positioned at the last seamed edge of a lower support framework.Bigger scaffold especially can make the enlarged diameter of a section and therefore reduce the danger of smoothing roll fracture, puts in its scaffold the inside separately by smoothing roll of this section.
Obtain one in the reliable solution that has higher service life aspect scaffold, bearing and the smoothing roll axle journal by the present invention.Reduce thus on using because corrective maintenance and safeguard the additional period that produces according to the leveling equipment of device of the present invention or equipment.Production efficiency has been enhanced.Can prolong the blanking time of maintenance in advance, this is embodied in the increase of production efficiency equally.Reduce the M R expense that is used for defective scaffold and scaffold and smoothing roll combination.

The specific embodiment
The Fig. 1 that has addressed in the above schematically represents, how described metallic article 1 is passing through on by smoothing roll 2,3 determined transport paths at one on by the throughput direction shown in the arrow 19 on the smoothing roll 2,3 when leveling.Described smoothing roll 2 constitutes one first smoothing roll secondary 10 and one second smoothing roll pair 11 of described smoothing roll 3 formations.The smoothing roll 2,3 of a smoothing roll pair 10,11 is adjacent to respectively be provided with.As what see in Fig. 1, the secondary 10 and second smoothing roll pair 11 of described first smoothing roll is provided with opposed to each other.
Fig. 2 illustrates one and according to prior art metallic article is carried out the device of leveling.As what seen, described smoothing roll 2,3 has a rolling roller 12 at the transport path position, acting on by its described smoothing roll will be by the goods of leveling, and it is rotatably mounted by the bearing journal 8 that puts in scaffold 6,7 respectively on its end.Several smoothing rolls 3 of the second smoothing roll pair 11 are by being used to support the supporting roller 4 and intermediate calender rolls 5 bendings of leveling process in the arrangement illustrated.This bending causes the relevant smoothing roll 3 of the second smoothing roll pair 11 and the load of its scaffold 7 to increase.
Fig. 3 illustrates the side view of Fig. 2.Described scaffold 6,7 is processed into waveform on a side of facing, the smoothing roll 2,3 of opposed smoothing roll pair 10,11 can be adjusted to a little spacing thus, and scaffold 6,7 is leaned and limit lateral feeding thus mutually.As shown in Figure 3, because the wave-like of scaffold makes for the space of smoothing roll supporting use very restricted.
Fig. 4 illustrates the smoothing roll supporting at the device shown in Fig. 2 and 3 according to prior art.This scaffold 6 has a dead eye 14, puts in a bearing journal 8 of smoothing roll 2 in this dead eye.Design corresponding narrowly at the diameter of the 20 li dead eyes 14 in the edge of dead eye 14 and bearing journal 8, the material thickness of scaffold 6 corresponding to wave-like, so this scaffold 6 can not or can only surpass the diameter of rolling roller 12 slightly at bearing journal 8 places at the scaffold shown in Fig. 36.If scaffold 6 20 surpasses rolling roller 12 in the edge, then will make scaffold 6 with colliding at the opposed scaffold 7 shown in Fig. 3.
For at the embodiments of the invention shown in Fig. 5, the scaffold 6,7 of described two smoothing roll pairs 2,3 the both sides of transport path smoothing roll 2,3 axially on setting mutually with staggering.Described scaffold 6,7 this is misplaced structure and realizes so in the embodiment shown, makes the smoothing roll 3 of the second smoothing roll pair 11 have the longer length of smoothing roll 2 of ratio first a smoothing roll pair 10.Since scaffold 6,7 be misplaced structure in the embodiment shown the scaffold 7 of the second smoothing roll pair 11 in drawing perpendicular to smoothing roll 2,3 axially on stretching, extension be not subjected to the restriction of the scaffold 6 of the first smoothing roll pair 10.Therefore the scaffold 7 of the described in the embodiment shown second smoothing roll pair 11 can more constitute significantly and therefore with carrying.Therefore the scaffold 6 of the first smoothing roll pair 10 puts between the scaffold 7 of the second smoothing roll pair 11 that is arranged on the transport path both sides in an illustrated embodiment.
Fig. 6 is illustrated in the embodiment shown in Fig. 5 with a side view.By this accompanying drawing as can be seen, the scaffold 6,7 of two smoothing roll pairs 10,11 puts in mutual overlapping part 17 perpendicular to transport path, and this position has a height h.Height h overlapping or overlapping part 17 preferably be at least a smoothing roll 2,3 rolling roller 12 diameter D 5%, preferably at least 10%, can act at the transport path position by this diameter will be by the goods 1 of leveling.In Fig. 6 height h surpass transport path, be smoothing roll the rolling roller place smoothing roll 2,3 diameter D 40%, promptly about 50%.
Have a unique scaffold 6,7 in each side of transport path respectively for each smoothing roll pairs of two smoothing roll pairs 10,11 in an illustrated embodiment, this will make the mechanical load of scaffold 6,7 improve and the processing of simplification device.But replace one unique, support 11 or 12 smoothing rolls 2 therein, 3 scaffold 6,7 also can be furnished with a plurality of less scaffolds, and in a plurality of less scaffolds, only support the smoothing roll 2 of smaller amounts, 3, support a unique smoothing roll 2,3 under special circumstances even only.
For support the leveling process also can with the smoothing roll 2,3 of the embodiment shown in Fig. 5 and 6 with can pass through supporting roller 4 and intermediate calender rolls 5 bendings in shown in Figure 2 according to one type of prior art syringe is the same.For more clear in Fig. 5 and 6 not shown supporting roller 4 and intermediate calender rolls 5.Scaffold 7 must make smoothing roll 3 remain on its position and realize crooked simultaneously together when described smoothing roll 3 is crooked like this.Described scaffold 7 is swingingly hung.
For the reason of machinery advantageously, two smoothing roll pairs 10,11 are provided with up and down and make down smoothing roll 3 bendings of smoothing roll pair 11.Because can realize on overstriking ground for the scaffold 7 of the second smoothing roll pair 11 in the embodiment shown in Fig. 5 and 6, the smoothing roll 3 of the second smoothing roll pair 11 is arranged on below the smoothing roll 2 of the first smoothing roll pair 10.
Fig. 7 illustrates two adjacent scaffolds 6,7 of described embodiment with the details cross-sectional view, and they have attached smoothing roll 2,3.As shown in the figure, described smoothing roll 2,3 puts in scaffold 6,7 the insides of its subordinate respectively with a section 18.Is a bearing journal 8 for the smoothing roll 2 according to the first smoothing roll pair 10 of prior art supporting basically on this section 18, and it is surrounded by journal bearing 13 in scaffold 6.This bearing journal 8 has one and compares littler diameter d * with the diameter D of leveling rolling roller 12.As shown in Figure 7, the space of using for the scaffold 6 of subordinate is because the smoothing roll 3 of the second smoothing roll pair 11 is restricted to very narrowly, so the material thickness of the scaffold 6 between the nearest smoothing roll 3 of the bearing journal 8 and the second smoothing roll pair 11 is 20 corresponding thinner in the edge.Therefore the scaffold 6 of the smoothing roll 2 of the second smoothing roll pair 10 and its subordinate is relative carries lessly.But this point does not have defective, because have only the smoothing roll 3 of the second smoothing roll pair 11 because crooked placing under the load of increase.
The smoothing roll 3 of the described second smoothing roll pair 11 puts in scaffold 7 the insides of its subordinate by a section 18, and this section has the diameter d identical with the rolling roller 12 of the smoothing roll 3 of the second smoothing roll pair 11.Therefore this smoothing roll 3 can bear very large load, thereby makes the special pettiness of its risk of breakage.Section 18 is constituted with the diameter d bigger than the diameter D of the rolling roller 12 of smoothing roll 3, put in the scaffold 7 of its subordinate by the described smoothing roll 3 of this section.When described section 18 was made of the bearing journal 8 of overstriking, the smoothing roll 3 by this section second smoothing roll pair 11 put in its scaffold separately, has been reduced to pettiness sufficiently for the described risk of breakage in most of application scenarios.
Usually advantageously, the smoothing roll 3 of the second smoothing roll pair 11 puts in its scaffold 7 the insides separately by a section 18, its diameter d be at least the second smoothing roll pair 11 smoothing roll 3 rolling roller 12 diameter D 55%, preferably be at least 66%.According to another favourable feature suggestion, smoothing roll pair, preferably the smoothing roll 3 of the second smoothing roll pair 11 puts in separately scaffold 7 the insides by a section 18, wherein the diameter d of this section 18 is greater than the diameter d * of section 21, by this section another, preferably the smoothing roll 2 of the first smoothing roll pair 10 puts in its scaffold 6 the insides.
Because at two scaffolds 6 shown in Fig. 7,7 be misplaced structure and the scaffold 7 of the smoothing roll 3 of the second smoothing roll pair 11 is extended in fact arbitrarily perpendicular to transport path far and therefore have an almost thickness arbitrarily around dead eye 14 circularly, this thickness only is subject to the distance of two adjacent smoothing rolls 3 of scaffold 7, and described smoothing roll 3 is positioned at the dead eye the inside.In order to get rid of the danger of scaffold 7 fractures as far as possible, should between the material thickness of scaffold 7, dead eye 14 and supporting diameter 8, select an optimum value.For example can advantageously stipulate, the material thickness of circular scaffold 7 around dead eye 14 be at least dead eye 14 diameters 25%, be preferably 40%.The material thickness of described in the embodiment shown in fig. 5 scaffold 7 is at least 50% of dead eye 14 diameters at the edge of the scaffold 7 20 circular dead eyes 14 that center on each direction.
In its dead eye 14 separately, additionally has a cod 15 respectively at two scaffolds 6,7 shown in Fig. 7 for described journal bearing 13.Sealing ring 16 sealed bearing holes 14 also make journal bearing 13 dustproof and moistureproof.
The structure that is misplaced of described scaffold 6,7 not only can realize in mode shown in Figure 5.And can put between the scaffold 6 of the first smoothing roll pair 10 at the one or more scaffolds 7 that make the second smoothing roll pair 11 on the side of transport path and on the opposite side at transport path one or more scaffolds 6 of the first smoothing roll pair 10 are put between the scaffold 7 of the second smoothing roll pair 11.In order in this selectable structure, on perpendicular to axial direction, also to have enough spaces, must make smoothing roll 2,3 usually by bearing journal 8 supportings with the width extending of scaffold 6,7 for scaffold 6,7 than macrostructure.Can make smoothing roll 2 then, 3 put in scaffold 6,7 the insides of another smoothing roll pair 10,11 separately by bearing journal 8, therefore described scaffold 6,7 can extend and covering or overlapping perpendicular to transport path further with the difference of the diameter of the diameter of rolling roller 12 and bearing journal 8.
Described device is an element that is used for the leveling equipment of rolling leveling or rolling leveling metallic article 1, especially thin plate and steel band.This device except described device, also comprise a series of other for the essential parts of operation, but they constitute according to prior art usually and therefore repeat no more.The parts that belong to this type of for example are one, and be used for will be by the feed arrangement of leveling goods, and one is used for the drive unit of smoothing roll or also can is a cross feed device, can regulate two distances between the smoothing roll pair corresponding to lamella thickness by it.In this leveling equipment, can drive or draw described smoothing roll.Described device is particularly useful for an extension-crooked leveling equipment.
