Aliuminio juostos tekstūruotu paviršiumi gamybos būdas ir įrenginysMethod and apparatus for producing a textured aluminum strip
Išradimas skirtas aliuminio arba aliuminio lydinio juostos tekstūruotu paviršiumi gamybos būdui ir įrenginiui pagal nepriklausomų išradimo apibrėžties 1 ir 5 punktų skiriamąsias dalis.The present invention relates to a method and apparatus for producing an aluminum or aluminum alloy strip with a textured surface according to the independent claims of claims 1 and 5.
Automobilių pramonėje yra naudojamos juostos ir skarda automobilio kėbulo dalims gaminti, kur, pavyzdžiui, skarda yra formuojama giliojo tempimo arba traukimo būdu. Šiam tempimui arba kitokiam formos pakeitimui turi būti naudojama tepimo priemonė. Taip valcavimo staklyne, sluoksniuojant juostas arba skardą, supaprastinamas ne tik formos pakeitimo procesas, bet ir pasiekiama optimali paviršiaus apsauga transportuojant ir saugant.In the automotive industry, bands and tin are used to make car body parts where, for example, the tin is formed by deep drawing or pulling. A lubricant must be used for this stretching or other deformation. This not only simplifies the process of reshaping the sheet or sheet, but also achieves optimal surface protection during transport and storage.
Šiuo metu įprastu būdu šaltai valcuota juosta juostos gamybos įrenginyje padengiama alyva arba bevandene sausa tepimo medžiaga ir toliau taip paruošta juosta kaip pusfabrikatis tiekiama užsakovui atitinkamų detalių gamybai giliuoju tempimu.At present, the cold rolled strip is routinely coated with oil or anhydrous dry lubricant in a belt fabrication plant, and the strip thus prepared as a semi-finished product is supplied to the customer for the production of the corresponding parts by deep drawing.
Įprastu būdu pagamintos aliuminio juostos apdoroto paviršiaus tekstūra atitinka darbo ritinėlių valcavimo šlifą. Ant pagamintos aliuminio juostos paviršiaus esanti darbui paruošta tepimo medžiaga santykinai blogai užtikrina patikimumą ir jos pasiskirstymą.Conventionally manufactured aluminum strips have a surface finish texture that corresponds to rollers on a roller. The ready-to-use lubricant on the surface of the fabricated aluminum strip provides relatively poor reliability and distribution.
Sausos tepimo medžiagos patikimumą ir pasiskirstymo savybes ant juostos paviršiaus žymiai pagerina šiurkštumo raštas, esantis ant juostos paviršiaus. Atitinkamais mikroreljefinės struktūros darbo ritinėlių paviršiais vykdomas skardos paviršiaus šiurkštinimas, kai, atitinkamai, šiurkštumo raštas pernešamas juostos šalto valcavimo ritinėliais.The reliability and the distribution properties of the dry lubricant on the web surface are greatly improved by the roughness pattern on the web surface. The respective surfaces of the working rolls of the microrelief structure are roughened by the tin surface, whereby the roughness pattern is carried by the rolled cold roll rolls, respectively.
Šiuo metu ant aliuminio juostos paviršiaus užnešto šiurkštaus paviršiaus patikimumo ir sausos tepimo medžiagos pasiskirstymo pagerinimas yra gaunamas naudojant darbo ritinėlius, kurie, pavyzdžiui, yra šiurkštinami apdorojant elektrokibirkštiniu būdu, elektroninės spinduliuotės būdu, arba PRETEX būdu. Visais šiais būdais gaunamas paviršiaus tekstūravimas, pasižymintis netvarkingu pasiskirstymu, uždaromis “tepimo priemonių kišenėlėmis”.Improvements in the rough surface reliability and dry lubricant distribution currently applied to the aluminum strip surface are achieved by the use of impellers, which are, for example, roughened by electrospray, electron beam or PRETEX. All of these give the surface a textured appearance, with an irregular distribution with closed "lubricant pockets".
Šiuo metu minėtas šiurkštumo raštas yra užnešamas ant juostos paviršiaus vykstant papildomam šalto valcavimo pratraukimui su nežymiu pratraukimo apspaudimu nuo maždaug 0,05 iki 15 %. Praktiškai šis papildomas šalto valcavimo pratraukimas yra siejamas su augančia produkcijos kaina. Be to, šiurkštumo rašto užnešimui privaloma numatytus darbo velenėlius su įprastu valcavimo šlifu kaitalioti su tekstūrinio valcavimo velenėliais.Currently, said roughness pattern is deposited on the surface of the strip with an additional cold-roll extension with a slight extension compression of about 0.05 to 15%. In practice, this additional cold-rolling extension is associated with the rising cost of production. In addition, for roughing, it is mandatory to alternate the intended working rolls with a conventional roller with a textured roller.
Šie minėti būdo ir įrenginio pavyzdžiai yra aprašyti EP-A 0945198.These aforementioned examples of method and device are described in EP-A 0945198.
Išradimo tikslas yra sukurti aukščiau minėtos rūšies būdą ir įrenginį, kurie sumažintų tekstūruotų juostų gamybos išlaidas. Tolimesnis tikslas yra supaprastinti gamybos įrangą, kadangi papildomas tekstūravimo pratraukimas sukelia gamybos pajėgumų praradimą.The object of the invention is to provide a method and a device of the aforesaid type which will reduce the cost of producing textured bands. A further aim is to simplify production equipment, since the additional texturing extension causes a loss of production capacity.
Tikslas pasiekiamas aliuminio juostos tekstūruotu paviršiumi gamybos būdu ir įrenginiu, kurio skiriamieji požymiai išdėstyti atitinkamai apibrėžties nepriklausomuose 1 ir 5 punktuose.The objective is achieved by means of a production of a textured aluminum strip and a device having the characteristics set out in the independent paragraphs 1 and 5 of the definition respectively.
Pagal šį būdą atskiras tekstūravimo praleidimas, priešingai, negu būde pagal technikos lygį, eliminuojamas iš technologinio proceso, taip sutaupant vieną valcavimo praleidimą.In this way, the individual texturing skip, in contrast to the state of the art, is eliminated from the technological process, thus saving one skipping skip.
Pagal geriausią būdo pagal šį išradimą įgyvendinimą šaltai valcuota juosta traukiama per valcavimo plyšį ir tekstūrinio valcavimo velenėliai sukasi spaudžiami prie juostos. Savaime aišku, tekstūrinio valcavimo velenėlius galima sukti aktyviau.In a preferred embodiment of the present invention, the cold rolled strip is pulled through a rolling slot and the rolls of the texture roll are pressed against the strip. It goes without saying that textured rolls can be spun more actively.
Atsiranda galimybė dėl juostos pastovaus storio visame plotyje tekstūrinio valcavimo velenėlius nustatyti teikiant pirmenybę pastoviai valcavimo jėgai.Due to the constant thickness of the bar over the entire width, it is possible to set the textured rolling rolls in favor of constant rolling force.
Ankščiau aprašytos juostos paviršiaus kaip sausos tepimo medžiagos nešiklio savybės suteikimui tekstūrinio valcavimo velenėliai yra šiurkštinami, geriausiai suteikiant mikroreljefąelektrokibirkštiniu būdu.To give the surface of the web as a dry lubricant as described above, the textured roller rolls are roughened, preferably by microrelief electro-sparking.
Buvo nustatyta, kad būdas pagal šį išradimą taip pat gali būti pritaikytas valcuotų juostų išlyginimui. Šiam tikslui pasiekti teigiama savybe gali būti tai, kad tekstūrinio valcavimo velenėliai yra numatyti su įprastais, turinčiais savybę paviršių apdoroti valcavimo staklynu, apdorojimui artinančiais nesudėtingais darbo valcavimo velenėlių valcavimo šlifais. Valcavimo velenėlius čia šlifuoja tik jų apskritimine kryptimi, tai yra valcavimo šlifas yra sudarytas iš daugelio lygiagrečių darbo valcavimo velenėlių apskritimu pasiskirsčiusių vagelių.It has been found that the method according to the present invention can also be adapted for the rolling of strips. A positive feature for this purpose may be that the textured roller rolls are provided with conventional roller mills approaching the surface of a rolling mill approaching the machining process. The roller rolls here are grinded only in their circumferential direction, that is, the roller roller is made up of a plurality of parallel working roller rollers.
Išradimo tikslui pasiekti taip pat tarnauja įrenginys, kuris yra išdėstytas tiesiogiai po šalto valcavimo staklyno, tekstūrinio valcavimo staklyno su tekstūrinio valcavimo velenėliais juostos judėjimo kryptimi. Tekstūrinio valcavimo velenėliai gali būti sujungti su varomąja įranga.Another object of the present invention is provided by a device which is positioned directly below the cold rolling mill, in the direction of web movement of the textured rolling mill with textured rolling rolls. Textured rolling rolls may be coupled to the drive unit.
Geriausias yra toks išdėstymas, kai tekstūrinio valcavimo staklyne tekstūrinio valcavimo velenėliai remiasi į tarpinius valcavimo velenėlius ir tarpiniai valcavimo velenėliai remiasi į atramos ritinėlius. Atramos ritinėliai gali būti išsidėstę keliais setais, išdėstytais tarpinių velenėlių ilgiu.The arrangement whereby the textured rolling rolls rest on the intermediate roll rolls and the intermediate roll rolls rest on the support rolls is the best arrangement. The support rollers may be arranged in several sets spaced along the length of the intermediate rollers.
Pageidautina, kad atramos ritinėliai būtų kinematiškai susiję su pastovia jėga, gaunama iš valdomų hidraulinių cilindrų.Preferably, the support rollers are kinematically related to the constant force obtained from the controlled hydraulic cylinders.
Dėl palyginti nedidelės apimties tekstūrinio valcavimo staklynas gali būti įtaisytas šalto valcavimo staklyno karkase.Due to the relatively small size of the textured rolling mill, it can be mounted on a cold rolling mill frame.
Kitos išradimo teigiamos savybės, požymiai ir detalės ryškėja iš tolimesnio geriausio išradimo įgyvendinimo pavyzdžio aprašymo, remiantis brėžiniais, kuriuose schematiškai pavaizduota:Other positive features, features, and details of the invention will be apparent from the following description of the preferred embodiment of the invention, taken in conjunction with the drawings in which:
Fig.1 įrenginio juostai tekstūruotu paviršiumi gaminti šoninis vaizdas;Fig. 1 is a side view of a strip for producing a textured surface;
Fig.2 tekstūrinio valcavimo staklyno vaizdas iš priekio;Fig. 2 is a front view of a textured rolling mill;
Fig.3 skersinis pjūvis per valcavimo staklyno išdėstymą pagal fig.2.Figure 3 is a cross-sectional view through the layout of the rolling mill according to Figure 2;
Fig. 1 pavaizduotas įrenginys, skirtas aliuminio juostai tekstūruotu paviršiumi gaminti, turi šalto valcavimo staklyną 1 su dviem darbiniais velenėliais 2, 3, tarp kurių yra suformuotas valcavimo plyšys 4, ir du darbinius velenėlius remiančius atramos velenėlius 5, 6. Darbiniai velenėliai 2, 3 ir atramos velenėliai 5,6 paprastai yra įtaisyti karkase 7.FIG. 1 illustrates an aluminum strip for producing a textured surface having a cold rolling mill 1 with two working rolls 2, 3, between which is formed a rolling slot 4, and two supporting rolls supporting the working rolls 5, 6. Working rolls 2, 3 and supports the rollers 5,6 are usually mounted in a frame 7.
Karkase 7 taipogi yra įmontuotas mažesnis, lyginant su šalto valcavimo staklynu 1, tekstūrinio valcavimo staklynas 8.The frame 7 is also equipped with a smaller one compared to a cold rolling mill 1 and a textured rolling mill 8.
Kaip parodyta fig. 2 ir fig. 3, tekstūrinio valcavimo staklynas 8 turi du tekstūrinio valcavimo plyšį 9 ribojančius tekstūrinio valcavimo velenėlius 10, 11, kurių kiekvienas remiasi į tarpinių velenėlių 12, 13 porą. Kiekviena tarpinių velenėlių 12, 13 pora remiasi į atramos ritinėlius 14, 15, sugrupuotus į penkis komplektus po tris. Atramos ritinėliai 14, 15 yra išdėstyti strypuose 16, 17, kurie nusidriekia per visą valcavimo plotį. Viršutinis strypas 16, spaudžiamas hidrauliniais slėgio cilindrais 18, atsiremia į viršutinę rėmo dalį 19; apatinis strypas 17 guli tiesiai ant apatinės rėmo dalies 20. Abi rėmo dalys 19, 20 per kėlimo arba nuleidimo cilindrus 21, 22 gali būti judinamos viena link kitos arba viena nuo kitos, tai yra, esant reikalui, tekstūrinio valcavimo plyšys 9 gali būti atidarytas, kai nereikalingas joks tekstūravimo etapas, arba, kai reikia, gali būti nustatyta tam tikra tekstūravimo praleidimui būtina jo dimensija. Valcavimo jėga yra reguliuojama hidrauliniais slėgio cilindrais 18 ir dėl to tekstūravimo metu ant juostos yra nustatomas jos apspaudimas pagal visą storį.As shown in FIG. 2 and FIG. 3, the textured rolling mill 8 has two textured rolling rolls 10, 11 which limit the textural rolling slot 9, each of which rests on a pair of intermediate rolls 12, 13. Each pair of intermediate rollers 12, 13 rests on support rollers 14, 15, grouped into five sets of three. The support rollers 14, 15 are arranged in bars 16, 17 which extend over the entire rolling width. The upper rod 16, pressed by hydraulic pressure cylinders 18, rests on the upper part 19 of the frame; the lower rod 17 lies directly on the lower part of the frame 20. The two frame parts 19, 20 can be moved towards each other or from one another via the lifting or lowering cylinders 21, 22, that is, the textured rolling slot 9 can be opened, when no texturing step is required, or when necessary, some dimension can be set for skipping texturing. The rolling force is controlled by the hydraulic pressure cylinders 18 and, as a result, the entire thickness of the web is determined during texturing.
Paviršiaus tekstūros užnešimui ant šoninio skritinio 23 užvyniotą šaltai valcuotą juostą, ją pasukus per pasukimo skritinį 24, nukreipia horizontalia x judėjimo kryptimi į šalto valcavimo staklyno 1 valcavimo plyšį 4. Kai juosta 25 išeina iš valcavimo plyšio 4, ji patenka į tekstūrinio valcavimo staklyno 8 tekstūrinio valcavimo plyšį 9. Juostai 25 išėjus iš tekstūrinio valcavimo staklyno 8, ji kreipiama per pasukimo skritinius 26, 27 ir po to užvyniojama ant suktuvo 28. Juostos storis tarp tekstūrinio valcavimo staklyno 8 ir antrojo pasukimo skritinio 26 yra tikrinamas storio matavimo įtaisu 29. Antrasis pasukimo skritinys 26 tuo pačiu metu tarnauja tekstūruotos juostos 25 lygumui tirti.For applying the surface texture to the side roller 23, the cold-rolled strip is rotated through the rotation roller 24 and is directed horizontally x in the rolling slot 4 of the cold rolling mill 1. The strip 25, after leaving the textured rolling mill 8, is guided through the turning rollers 26, 27 and then wrapped on a roller 28. The thickness of the strip between the textured rolling mill 8 and the second turning roller 26 is checked by a thickness gauge 29. the roll 26 simultaneously serves to investigate the smoothness of the textured strip 25.
Šalto valcavimo staklyno 1 darbiniai valcavimo velenėliai 2, 3 yra sukami ir juosta 25 slenka valcavimo velenėliais per valcavimo plyšį 4. Tekstūrinio valcavimo velenėliai gali suktis aktyviai arba jie gali ir nesisukti. Jeigu tekstūrinio valcavimo ritinėliai 10, 11 nesisuka, tuomet juosta 25 per tekstūrinį valcavimo staklyną 8 yra tempiama. Tempimas atliekamas naudojant suktuvą 28. Stabdymas tekstūrinio valcavimo velenėliais 10-11 sukuria įtempimo reguliavimo efektą kuris leidžia pagerinti tekstūruotos juostos 25 lygumą.The working rolls 2, 3 of the cold rolling mill 1 are pivotable and the web 25 slides on the rolling rolls through the rolling slit 4. The textured rolling rolls may rotate actively or may not rotate. If the textured rolling rolls 10, 11 do not rotate, then the web 25 is pulled through the textured rolling mill 8. Stretching is performed using a spinner 28. Braking with textured rolling rolls 10-11 produces a tension adjustment effect that allows the smoothness of the textured web 25 to be improved.
Tekstūrinio valcavimo velenėlių 10, 11 skersmuo yra akivaizdžiai mažesnis, negu besisukančių šalto valcavimo staklyno 1 darbinių valcavimo velenėlių 2, 3 skersmuo. Tai leidžia pagerinti juostos paviršiaus tekstūrą taip, kad tam reikia naudoti mažesnio apspaudimo praleidimą. Tekstūrinio valcavimo velenėlio skersmuo gali būti apie 350 mm.The diameter of the textured rolling rolls 10, 11 is clearly smaller than the diameter of the rotating cold rolling mill 1, working rolls 2, 3. This allows you to improve the surface texture of the tape so that it requires less compression skipping. The diameter of the textured rolling roll may be about 350 mm.
